背景技术Background technique
目前，闸阀广泛用于石油、化工、制药、冶金、煤碳、电力行业、城市给排水等行业的管路上，用于控制管路介质流通和截断，是各种流体输送工程中应用最广泛的阀门之一。闸阀是启闭件，阀板沿中心垂直方向移动，向上移动为开启，向下移动为关闭的阀门。明杆闸阀是手轮带动螺母作圆周运动时，阀杆带动阀板作直线运动，从而达到阀板的开启与关闭，从而使闸阀满足启闭功能。当需要频繁进行闸阀的开关作业时，使用螺杆带动闸板运动的方式则较为费力，而且在外观上并不能判断阀门的启闭状态。At present, gate valves are widely used in pipelines in petroleum, chemical, pharmaceutical, metallurgy, coal, electric power, urban water supply and drainage industries to control the flow and cut-off of pipeline media, and are the most widely used in various fluid transportation projects. One of the valves. The gate valve is an opening and closing part, the valve plate moves vertically along the center, the valve moves upward to open and downward to close. In the rising stem gate valve, when the hand wheel drives the nut to make a circular motion, the valve stem drives the valve plate to make a linear motion, so as to achieve the opening and closing of the valve plate, so that the gate valve can meet the opening and closing function. When the gate valve needs to be frequently switched on and off, it is more laborious to use the screw to drive the gate to move, and the opening and closing state of the valve cannot be judged from the appearance.

具体使用时，如图1所示，转动不完全齿轮10，带动齿条9向上移动，从而带动阀杆3向上移动，阀板2向上移动，阀门打开，同时，限位板7向上移动，挤压压紧弹簧8；如图2所示，继续转动不完全齿轮10，不完全齿轮10的无齿部分与齿条9失去啮合，在压紧弹簧8的作用下，齿条9向下移动，从而阀板2向下移动，实现阀门的关闭。该开关装置可以提高阀门的启闭速度，特别适用于频繁启闭阀门。During specific use, as shown in Figure 1, the incomplete rotation of the gear 10 drives the rack 9 to move upward, thereby driving the valve stem 3 to move upward, the valve plate 2 to move upward, and the valve is opened. At the same time, the limiting plate 7 moves upward to squeeze Press the compression spring 8; as shown in Figure 2, continue to rotate the incomplete gear 10, the toothless part of the incomplete gear 10 loses engagement with the rack 9, and under the action of the compression spring 8, the tooth bar 9 moves downward, Thus, the valve plate 2 moves downward to realize the closing of the valve. The switching device can increase the opening and closing speed of the valve, and is especially suitable for frequently opening and closing the valve.
所述阀杆3的上端设有刻度线12。通过刻度线12判断阀杆3向上移动的距离，从而判断阀门的启闭状态以及开启的大小。The upper end of the valve stem 3 is provided with a scale line 12 . The upward movement distance of the valve rod 3 is judged by the scale line 12, thereby judging the opening and closing state of the valve and the size of the opening.
如图4所示，所述手柄11上设有限位通孔16，闸阀帽4上设有限位孔17，限位销钉18插入限位通孔16和限位孔17对手柄11进行限位。As shown in FIG. 4 , the handle 11 is provided with a limiting through hole 16 , and the gate valve cap 4 is provided with a limiting hole 17 , and a limiting pin 18 is inserted into the limiting through hole 16 and the limiting hole 17 to limit the handle 11 .
当阀门处于完全开启状态时，限位孔17与限位通孔16相对应，通过将销钉18同时插入限位通孔16和限位孔17实现阀门的锁定。一方面能够使阀门处于完全开启状态，另一方面方便对手柄11的误操作而造成阀门关闭。When the valve is fully open, the limiting hole 17 corresponds to the limiting through hole 16, and the locking of the valve is realized by inserting the pin 18 into the limiting through hole 16 and the limiting hole 17 at the same time. On the one hand, the valve can be fully opened, and on the other hand, it is convenient to close the valve due to misoperation of the handle 11 .
所述弹簧槽6侧壁设有滑槽19，限位板7两端沿滑槽19滑动。通过设置滑槽19，对限位板7起到限位作用。The side wall of the spring groove 6 is provided with a slide groove 19 , and the two ends of the limiting plate 7 slide along the slide groove 19 . By setting the chute 19, the limiting plate 7 can be limited.
实施例2：如图1~3所示，所述阀杆3上端两侧设有第二支撑块13，阀杆3上设有与第二支撑块13配合的安装槽14，第二支撑块13和安装槽14之间设有弹簧15。Embodiment 2: As shown in Figures 1 to 3, a second support block 13 is provided on both sides of the upper end of the valve stem 3, and a mounting groove 14 for matching with the second support block 13 is provided on the valve stem 3, and the second support block A spring 15 is arranged between 13 and the mounting groove 14 .
当阀杆3设置第二支撑块13的位置在第一支撑块5供阀杆3通过的通孔中时，第二支撑块13挤压弹簧15，弹簧15处于压紧状态，随着不完全齿轮10的转动，阀杆3上移，当第二支撑块13位于闸阀帽4上侧时，由于弹簧15的弹力，第二支撑块13伸出安装槽14外，不完全齿轮10继续转动，不完全齿轮10与齿条9脱离啮合，在压紧弹簧8的作用下，阀杆3向下移动，由于第二支撑块13的限位作用，阀杆3停止下移，此时，阀门处于完全开启状态，第二支撑块13对阀门进行锁定；当需要关闭阀门时，同时向安装槽14方向按压第二支撑块13，第二支撑块13压入安装槽14内，在压紧弹簧8的作用下，阀杆3下移，实现阀门关闭。When the valve rod 3 is provided with the position of the second support block 13 in the through hole of the first support block 5 for the valve rod 3 to pass through, the second support block 13 squeezes the spring 15, and the spring 15 is in a compressed state. When the gear 10 rotates, the valve stem 3 moves up. When the second support block 13 is located on the upper side of the gate valve cap 4, due to the elastic force of the spring 15, the second support block 13 protrudes out of the installation groove 14, and the incomplete gear 10 continues to rotate. The incomplete gear 10 is disengaged from the rack 9. Under the action of the compression spring 8, the valve stem 3 moves downward. Due to the limiting effect of the second support block 13, the valve stem 3 stops moving downward. At this time, the valve is in the In the fully open state, the second support block 13 locks the valve; when the valve needs to be closed, press the second support block 13 in the direction of the installation groove 14 at the same time, and the second support block 13 is pressed into the installation groove 14, and the compression spring 8 Under the action of the valve stem 3 moves down to realize the valve closing.
