技术领域technical field
本实用新型涉及对接接头技术领域，尤指一种分体式对接接头及其公接头和母接头。The utility model relates to the technical field of butt joints, in particular to a split type butt joint and its male and female joints.
背景技术Background technique
对接接头是广泛应用于管路间，具有快速扣接和快速拆卸的性能，对于一些与气体或液体相关的行业而言具有密不可分的关系。市场上的快速接头存在两类特点，第一类特点是结构简单、操作便捷，自动扣固及弹脱，但气密效果不太理想，尤其是压力越高的情况下，密封效果越差，并且动作不准确；第二类特点是结构复杂，组装慢，但气密性好，动作准确，可自动扣固及弹脱。Butt joints are widely used in pipelines, with quick buckle and quick disassembly performances, and have an inseparable relationship with some industries related to gas or liquid. There are two types of quick connectors on the market. The first type is characterized by simple structure, convenient operation, automatic buckle and spring release, but the airtight effect is not ideal, especially when the pressure is higher, the sealing effect is worse. And the action is not accurate; the second type is characterized by complex structure, slow assembly, but good air tightness, accurate action, and automatic fastening and springing.
目前，上述第二类的对接接头阀芯一般均采用一体式阀芯，即通过在公接头内的公阀芯和母接头的母阀芯上均设置用于放置密封圈的槽，以保证未对接时，公接头和母接头自身的气密性，进而保证对接接头的动作准确，可自动扣固及弹脱等功能。但是由于阀芯(即公阀芯和母阀芯)的尺寸较小，这样密封圈的尺寸也必须小，在较小尺寸的阀芯上加工用于容置较小尺寸密封圈的槽更是难上加难，不仅槽的加工困难；由于加工槽时，是有加工误差的，因此槽与密封圈之间的适配性差，导致密封圈无法安装，这样就导致整个对接接头的无法组装，浪费安装时间以及加工原料，增加了对接接头的生产成本和组装成本，导致其加工效率低；或密封圈可在槽内移动，这样导致在安装或使用过程中，密封圈在槽内存在移动，长时间使用中，更加会加剧移动现象，从而导致对接接头密封性降低，使得接头内的流体(即气体或液体)泄露，严重影响了对接接头的使用寿命和工作效率。At present, the spools of the above-mentioned second type of butt joints generally adopt integral spools, that is, grooves for placing sealing rings are arranged on the male spool in the male joint and the female spool of the female joint to ensure that no When docking, the airtightness of the male joint and the female joint itself ensures the accurate movement of the butt joint, and can automatically buckle and pop off functions. However, due to the small size of the spool (that is, the male spool and the female spool), the size of the sealing ring must also be small. The difficulty is even more difficult, not only the processing of the groove is difficult; because there are processing errors in the processing of the groove, the adaptability between the groove and the sealing ring is poor, resulting in the failure of the sealing ring to be installed, which leads to the inability to assemble the entire butt joint. Waste of installation time and processing raw materials, increase the production cost and assembly cost of the butt joint, resulting in low processing efficiency; or the sealing ring can move in the groove, which leads to the movement of the sealing ring in the groove during installation or use, During long-term use, the phenomenon of movement will be aggravated, thereby reducing the sealing performance of the butt joint, causing the fluid (ie gas or liquid) in the joint to leak, seriously affecting the service life and work efficiency of the butt joint.
因此，本申请致力于研究一种易加工的分体式对接接头及其公接头和母接头。Therefore, the present application is dedicated to researching an easy-to-process split butt joint and its male and female joints.

Due to the increased size of the groove, the compatibility between the seal and the groove is greatly improved, and the difficulty of installing the seal is greatly reduced. And because the matching valve core is set on one side of the seal, the position of the seal in the groove is fixed and it is not easy to move, thus ensuring the airtightness of the split male connector and prolonging the service life of the split male connector , which saves the processing cost, use cost and maintenance cost of the split male connector.

In addition, to make the drawings concise and easy to understand, in some drawings, only one of the components having the same structure or function is schematically shown, or only one of them is marked. Herein, "a" not only means "only one", but also means "more than one". In this article, the descriptions of up, down, left, right, front and back are for the drawings described and do not fully represent the actual situation.
在实施例一中，如图1和2所示，一种分体式公接头，包括：公阀体11，公阀体11沿轴向开设有第一流体通道111；活塞16，活塞16滑动设于公阀体11的第一流体通道111内；公阀芯体12，公阀芯体12套设于活塞16；公阀芯体12在其与活塞16接触的位置开有用于容置第一密封件13和配套公阀芯14的第一沟槽121。本分体式公接头1主要由公阀体11、活塞16、公阀芯体12以及设置在其上的第一密封件13和配套公阀芯14组成，上述各个部件均可根据实际需要的尺寸单独进行设计和加工，然后进行组装，单独加工各个部件的步骤较少且易于加工，更优的，由于第一密封件13和配套公阀芯14共同设置在第一沟槽121内，使得第一沟槽121的尺寸变大，使得沟槽更易于加工，且沟槽可一次性加工成型，非常简单，且易于操作，提高了产品的生产效率；且加工过程中因为沟槽尺寸大，加工完成且退刀时，不易出现加工毛刺或刺边，进而避免了密封件的无法安装或被割裂的现象。由于沟槽尺寸加大，密封件与沟槽的适配性大大提高，大大降低了密封件的安装难度。且由于配套阀芯抵设于密封件的一侧，使得密封件在沟槽内的位置固定，不易移动，从而保证了分体式公接头1的气密性，进而延长了分体式公接头1的使用寿命，节约了分体式公接头1的加工成本、使用成本和维护成本。本发明的产品实用性强，实用范围广，具有良好的市场前景。由于本分体式公接头1是通过各个部件组合形成的，因此，当分体式公接头1的某一部件损坏时，可通过更换、维修该损坏的部件即可，而无需整体替换，大大节约了本分体式公接头1的生产成本、使用成本、维护成本，符合我国优良的勤俭节约的传统美德。In Embodiment 1, as shown in Figures 1 and 2, a split-type male joint includes: a male valve body 11, the male valve body 11 is provided with a first fluid passage 111 along the axial direction; In the first fluid channel 111 of the male valve body 11; the male valve core body 12, the male valve core body 12 is sleeved on the piston 16; The sealing member 13 and the first groove 121 of the matching male valve core 14 . The split type male joint 1 is mainly composed of a male valve body 11, a piston 16, a male valve core body 12, a first sealing member 13 and a supporting male valve core 14 arranged on it, and each of the above components can be adjusted according to the actual size Designing and processing separately, and then assembling, the steps of separately processing each part are less and easy to process, and more preferably, because the first sealing member 13 and the matching male valve core 14 are jointly arranged in the first groove 121, so that the second The size of a groove 121 becomes larger, which makes the groove easier to process, and the groove can be processed and formed at one time, which is very simple and easy to operate, which improves the production efficiency of the product; and because the groove size is large during processing, the processing When the tool is completed and withdrawn, it is not easy to have processing burrs or burrs, thereby avoiding the phenomenon that the seal cannot be installed or is cut. Due to the increased size of the groove, the compatibility between the seal and the groove is greatly improved, and the difficulty of installing the seal is greatly reduced. And because the supporting valve core is set against one side of the seal, the position of the seal in the groove is fixed and not easy to move, thereby ensuring the airtightness of the split male connector 1 and extending the life of the split male connector 1. The service life saves the processing cost, use cost and maintenance cost of the split male connector 1. The product of the invention has strong practicability, wide application range and good market prospect. Since the split-type male connector 1 is formed by combining various parts, when a certain part of the split-type male connector 1 is damaged, the damaged part can be replaced and repaired instead of the whole replacement, which greatly saves costs. The production cost, use cost and maintenance cost of the split-type male connector 1 are in line with the excellent traditional virtues of diligence and thrift in our country.
在实施例二中，如图1和2所示，在实施例一的基础上，第一沟槽121包括第一子沟槽(图中未标示)和第二子沟槽(图中未标示)；第一子沟槽的底面与公阀芯体12的轴线之间的距离不小于第二子沟槽的底面与公阀芯体12的轴线之间的距离。且第一子沟槽远离第一流体通道111设置，其用于容置第一密封件13；第二子沟槽用于容置配套公阀芯14；配套公阀芯14抵设于第一密封件13靠近第一流体通道111的一侧(即远离分体式母接头2的一侧)。本实施例中，通过配套公阀芯14将第一密封件13抵设在远离第一流体通道111的一侧，由于配套公阀芯14为硬质材质，因此弹性材质第一密封件13被第一子沟槽的侧壁和配套公阀芯14这两个较硬材质的部件夹设在固定的空间内，使得第一密封件13被限制在预设空间内而不得移动，因此，随着分体式公接头1使用时间的延长，第一密封件13也不会出现移动的现象，从而保证了分体式公接头1长时间的密封性能，延长了分体式公接头1的使用时效。更优的是，用于容置第一密封件13的第一子沟槽的底面和用于容置配套公阀芯14的第二子沟槽的底面为阶梯状，即第一子沟槽的底面与公阀芯体12的轴线之间的距离大于第二子沟槽的底面与公阀芯体12的轴线之间的距离，这样配套公阀芯14在安装时，无法越过两个底面之间形成的肩部(图中未标示)，就不会出现在安装配套公阀芯14时出现配套公阀芯14挤压第一密封件13而导致第一密封件13变形而降低其与活塞16的活塞密封面161的适配性，受挤压的第一密封件13的径向尺寸变大而导致配套公阀芯14的密封面无法与活塞密封面161紧密贴合，进而可能导致分体式公接头1组装失败，且即使组装成功，本产品的密封性能仅仅只能依靠第一密封件13来实现，而第一密封件13是易耗产品，耐磨性能差且易变形，使用寿命短，进而影响本产品的使用寿命。进一步优选地，第一密封件13与第一子沟槽适当过盈配合，这样第一密封件13还可以缓冲配套公阀芯14安装或使用过程中与公阀芯体12之间的硬性接触，降低配套公阀芯14与公阀芯体12之间的机械磨损，进而延长其使用寿命，还避免机械碎屑进入本产品的第一流体通道111内流动的流体内，污染流体而带来的不良后果。In the second embodiment, as shown in Figures 1 and 2, on the basis of the first embodiment, the first groove 121 includes a first sub-groove (not marked in the figure) and a second sub-groove (not marked in the figure). ); the distance between the bottom surface of the first sub-groove and the axis of the male valve core body 12 is not less than the distance between the bottom surface of the second sub-groove and the axis of the male valve core body 12 . And the first sub-groove is set away from the first fluid channel 111, which is used to accommodate the first sealing member 13; the second sub-groove is used to accommodate the matching male valve core 14; the matching male valve core 14 is arranged on the first The side of the seal 13 close to the first fluid channel 111 (ie the side away from the split female connector 2 ). In this embodiment, the first sealing member 13 is arranged on the side away from the first fluid passage 111 through the matching male valve core 14. Since the matching male valve core 14 is made of hard material, the first sealing member 13 made of elastic material is The side wall of the first sub-groove and the matching male spool 14 are sandwiched in a fixed space by the two relatively hard parts, so that the first sealing member 13 is restricted in the preset space and cannot move. As the use time of the split male connector 1 is extended, the first sealing member 13 will not move, thereby ensuring the long-term sealing performance of the split male connector 1 and prolonging the service life of the split male connector 1 . More preferably, the bottom surface of the first sub-groove for accommodating the first seal 13 and the bottom surface of the second sub-groove for accommodating the matching male valve core 14 are stepped, that is, the first sub-groove The distance between the bottom surface of the groove and the axis of the male valve core body 12 is greater than the distance between the bottom surface of the second sub-groove and the axis of the male valve core body 12, so that the matching male valve core 14 cannot cross the two bottom surfaces when installed. The shoulders (not shown in the figure) formed between them will not appear when the matching male valve core 14 is installed, and the matching male valve core 14 will squeeze the first sealing member 13 and cause the deformation of the first sealing member 13 and reduce its compatibility with the first sealing member 13. The adaptability of the piston sealing surface 161 of the piston 16, the radial dimension of the extruded first sealing member 13 becomes larger, so that the sealing surface of the matching male valve core 14 cannot be closely attached to the piston sealing surface 161, which may cause The assembly of the split type male joint 1 fails, and even if the assembly is successful, the sealing performance of this product can only be realized by the first seal 13, and the first seal 13 is a consumable product with poor wear resistance and easy deformation. The service life is short, which in turn affects the service life of this product. Further preferably, the first sealing member 13 is appropriately interference-fitted with the first sub-groove, so that the first sealing member 13 can also buffer the hard contact between the matching male valve core 14 and the male valve core body 12 during installation or use. , reduce the mechanical wear between the matching male valve core 14 and the male valve core body 12, thereby prolonging its service life, and avoiding mechanical debris entering the fluid flowing in the first fluid passage 111 of the product, contaminating the fluid and causing adverse consequences.

When the product is docked or withdrawn from the docking process, the first stopper 15 can effectively prevent the phenomenon that the male valve core 12 and the first seal 13 slide towards the right due to friction when sliding friction with the piston 16 , thereby ensuring the stability and firmness of the male valve core body 12 and the first sealing member 13 in the first groove 121, thus further ensuring the good sealing performance and service life of the product. Of course, both the male valve core body 12 and the supporting male valve core 14 have a coaxial first through hole along the direction perpendicular to the axis of the male valve body 11; the first through hole is used to place the first fixing part (not marked in the figure, It is preferably pin shaft); through the first through hole on the male valve core body 12 and the matching male valve core 14 simultaneously through the first fixing piece, thereby realizing that the supporting male valve core 14 is fixedly arranged on the male valve core body 12, and at the same time This prevents the male valve core body 12 and the first sealing member 13 from slipping toward the right side due to frictional force when sliding friction occurs with the piston 16 .

在实施例十中，如图1和2所示，一种分体式对接接头，包括：上述任意所述的分体式公接头1和上述任意所述分体式母接头2，分体式公接头1与分体式母接头2相适配；分体式公接头1的公阀体11的第一流体通道111与分体式母接头2的母阀体21的第二流体通道212相对设置；分体式公接头1的公阀芯体12与分体式母接头2的母阀芯体22正对设置。基于上述分体式公接头1和分体式母接头2加工方便，成品率高，组装方便，密封性能好，使用寿命长，实用性强，适用范围广，具有良好的市场前景，因此，由上述分体式公接头1和分体式母接头2组装而成的本分体式对接接头同样具有上述优点。且由于本分体式对接接头的分体式公接头1和分体式母接头2是单独存在、且分体式公接头1和分体式母接头2的各部分是组装而成，每个部件可单独加工和生产，因此在本分体式对接接头的某一部件或某一个分体式接头损坏时，可通过更换、维修该损坏的部件即可，而无需整体替换，大大节约了本分体式对接接头的生产成本、使用成本、维护成本，符合我国优良的勤俭节约的传统美德。In the tenth embodiment, as shown in Figures 1 and 2, a split-type butt joint includes: any of the above-mentioned split-type male connectors 1 and any of the above-mentioned split-type female connectors 2, the split-type male connector 1 and The split female connector 2 is compatible; the first fluid channel 111 of the male valve body 11 of the split male connector 1 is opposite to the second fluid channel 212 of the female valve body 21 of the split female connector 2; the split male connector 1 The male valve core body 12 of the split type female connector 2 and the female valve core body 22 are arranged facing each other. Based on the above split male connector 1 and split female connector 2 are easy to process, high yield, easy assembly, good sealing performance, long service life, strong practicability, wide application range, and good market prospects, therefore, from the above points The split-type butt joint assembled from the body-type male connector 1 and the split-type female connector 2 also has the above-mentioned advantages. And because the split male connector 1 and the split female connector 2 of the split butt joint exist separately, and each part of the split male connector 1 and the split female connector 2 is assembled, each part can be processed and processed separately. Therefore, when a certain part of the split-type butt joint or a certain split-type joint is damaged, the damaged part can be replaced and repaired without the need for overall replacement, which greatly saves the production cost of the split-type butt joint , use cost, and maintenance cost are in line with my country's excellent traditional virtues of diligence and thrift.
在实际应用中，当分体式公接头1与分体式母接头2未处于对接状态时，公阀体11的第一流体通道111靠近分体式母接头2一侧的端部处于密封状态，母阀体21的第二流体通道212靠近分体式公接头1一侧的端部处于密封状态；当分体式公接头1与分体式母接头2处于对接状态时，公阀芯体12和母阀芯体22相互顶压，公阀体11的第一流体通道111和母阀体21的第二流体通道212处于连通状态。In practical applications, when the split male connector 1 and the split female connector 2 are not in the docking state, the end of the first fluid channel 111 of the male valve body 11 close to the split female connector 2 is in a sealed state, and the female valve body The end of the second fluid channel 212 of 21 close to the split type male connector 1 is in a sealed state; when the split type male connector 1 and the split type female connector 2 are in the docking state, the male valve core body 12 and the female valve core body 22 are mutually Push pressure, the first fluid channel 111 of the male valve body 11 and the second fluid channel 212 of the female valve body 21 are in a communication state.
当分体式公接头1和分体式母接头2对接时，如图2所示，由于公阀芯体12远离分体式母接头2一侧的端部固设在公阀体11的端座上，而活塞16是活动设于公阀体11靠近分体式母接头2一侧的第一流体通道111上；母阀芯体22远离分体式公接头1一侧的端部滑动设于滑动孔271上；因此，分体式公接头1靠近分体式母接头2时，活塞16会和母阀体21的母阀体端面213相接触，且公阀芯体12会和母阀芯体22相接触，当分体式公接头1继续靠近分体式母接头2时，活塞16被母阀体端面213抵向右滑动，而公阀芯体12却不动，此时公阀芯体12会将母阀芯体22向左抵压，使得母阀芯体22和公阀芯体12均向左运动，此时，配套公阀芯14与活塞16之间由相互密封连接状态转变成相互脱离状态，同样的，配套母阀芯24和母阀体21的母阀体密封面211之间也由相互密封连接状态转变成相互脱离状态；此时分体式公接头1的第一流体通道111和分体式母接头2的第二流体通道212相连通，因而流体可在分体式公接头1和分体式母接头2之间流动；此时，由于活塞16向右运动将第一压簧17向右压缩，使得公阀体11内的第一压簧17处于被压缩状态；由于母阀芯体22向左运动将第二压簧26向左压缩，母阀体21内的第二压簧26处于被压缩状态。When the split male connector 1 and the split female connector 2 are docked, as shown in Figure 2, since the end of the male valve body 12 away from the split female connector 2 is fixed on the end seat of the male valve body 11, The piston 16 is movably arranged on the first fluid channel 111 on the side of the male valve body 11 close to the split-type female connector 2; the end of the female valve core body 22 away from the split-type male connector 1 is slidably arranged on the sliding hole 271; Therefore, when the split-type male joint 1 is close to the split-type female joint 2, the piston 16 will be in contact with the female valve body end surface 213 of the female valve body 21, and the male valve core body 12 will be in contact with the female valve core body 22. When the male joint 1 continues to approach the split female joint 2, the piston 16 is pushed to the right by the end face 213 of the female valve body, while the male valve body 12 does not move. At this time, the male valve body 12 will push the female valve body 22 to the right. The left presses, so that both the female spool body 22 and the male spool body 12 move to the left. At this time, the matching male spool 14 and the piston 16 are transformed from a mutually sealed connection state to a mutual disengagement state. The valve core 24 and the female valve body sealing surface 211 of the female valve body 21 are also transformed from a mutual sealing connection state to a mutual disengagement state; The fluid channel 212 is connected, so the fluid can flow between the split type male connector 1 and the split type female connector 2; at this time, due to the rightward movement of the piston 16, the first compression spring 17 is compressed to the right, so that the inside of the male valve body 11 The first compression spring 17 in the female valve body 21 is in a compressed state; because the female valve body 22 moves to the left and the second compression spring 26 is compressed to the left, the second compression spring 26 in the female valve body 21 is in a compressed state.
当分体式公接头1和分体式母接头2退出对接状态时，如图1所示，分体式公接头1向右运动，由于第二压簧26的回复力使母阀芯体22朝右运动，同时，第一压簧17的回复力使活塞16朝向左运动，使得分体式公接头1与分体式母接头2未完全脱离之间，活塞16靠近分体式母接头2一侧的端面和母阀体端面213始终处于抵压状态，避免此过程出现流体泄露的现象，直至分体式公接头1和分体式母接头2完全脱离时，配套公阀芯14的密封面与活塞密封面161面接触式连接；配套母阀芯24的密封面与母阀体密封面211面接触式连接，避免了分体式公接头1和分体式母接头2处于未对接状态时流体的泄露。可见，无论是分体式公接头1和分体式母接头2处于正在对接状态、对接状态、退出对接状态还是未对接状态，均无流体泄露的现象，保证了对接接头的密封性能、工作效率。When the split male connector 1 and the split female connector 2 exit the docking state, as shown in FIG. At the same time, the restoring force of the first compression spring 17 moves the piston 16 to the left, so that the split male connector 1 and the split female connector 2 are not completely disengaged, and the piston 16 is close to the end surface of the split female connector 2 and the female valve. The body end surface 213 is always in a pressing state to avoid fluid leakage during this process. When the split male connector 1 and the split female connector 2 are completely separated, the sealing surface of the matching male valve core 14 is in surface contact with the piston sealing surface 161. Connection; the sealing surface of the mating female valve core 24 is connected in contact with the sealing surface 211 of the female valve body, which avoids fluid leakage when the split male connector 1 and the split female connector 2 are in an undocked state. It can be seen that no matter whether the split male connector 1 and the split female connector 2 are in the docking state, docking state, withdrawn docking state or undocked state, there is no fluid leakage phenomenon, which ensures the sealing performance and working efficiency of the butt joint.
