Abstract

A solenoid valve includes a movable valve portion having a valve body for opening and closing a fluid passage, a first magnetic conductor at an opposite end of the valve body, and a first spring for holding the valve body in a position for intercepting the fluid passage; an operation portion moving toward the valve portion, including a second magnetic conductor, and a second spring holding the second magnetic conductor at a position away from the first magnetic conductor; and a coil for generating an electromagnetic field, disposed between the first and second magnetizers. When current flows through the coil, the second magnetizer becomes an electromagnet and attracts the first magnetizer when the operating part is pressed by hand, and the operating part is pushed back to the original position by the elastic force of the second spring when the hand leaves, and simultaneously drives the valve part and the coil to displace, so that the valve body acts as an open valve position to open the fluid passage. When the current is cut off, the valve unit returns to the original position by the elastic force of the first spring due to the disappearance of the electromagnetic force, and the valve body returns to the closed valve position to block the fluid passage.

电磁阀The electromagnetic valve

技术领域technical field

本实用新型是关于一种电磁阀，尤指一种在加上电压时，必须用人手去操作才能开启的电磁阀。The utility model relates to an electromagnetic valve, in particular to an electromagnetic valve which can only be opened by manual operation when voltage is applied.

背景技术Background technique

电磁阀是利用电磁铁的吸引力使阀开闭，作为空气、燃气、油、水等流体的断续控制与方向控制。Solenoid valve uses the attraction force of electromagnet to make the valve open and close, as the intermittent control and direction control of air, gas, oil, water and other fluids.

一般电磁阀是由作为电磁铁的线圈与开闭流体通路的阀所构成。图1显示习惯用常闭型电磁阀的动作流程，在用作电磁铁的线圈流过电流时，阀因电磁力作用成开阀位而开启流体通路，相反地电流被切断时，阀复归闭阀位，截断流体通路。简单的说，电磁阀是靠电气式作用而自动开闭流体通路，不必用手去操作，就能达成目的。A general solenoid valve consists of a coil as an electromagnet and a valve that opens and closes a fluid passage. Figure 1 shows the action flow of the conventional normally closed solenoid valve. When the coil used as the electromagnet flows through the current, the valve is opened to the open position due to the electromagnetic force and the fluid passage is opened. Conversely, when the current is cut off, the valve returns to close. Valve position, blocking fluid passage. Simply put, the solenoid valve automatically opens and closes the fluid passage by electrical action, and it can achieve its purpose without manual operation.

自动控制虽然方便。但是，在利用电磁阀开闭流体通路的同时，常会要求更安全的控制机能。若使用传统的电磁阀作为流体的断续控制与方向控制，一旦不安全因素尚未排除，在电压加上的瞬间就会因为电磁阀自动开启，而导致可能十分严重的后果。Automatic control is convenient though. However, while using the solenoid valve to open and close the fluid passage, a safer control function is often required. If the traditional solenoid valve is used as the intermittent control and direction control of the fluid, once the unsafe factors have not been eliminated, the solenoid valve will automatically open the moment the voltage is applied, which may lead to very serious consequences.

在此以电磁阀用于开闭瓦斯通路为例。假设瓦斯器具在使用中，因为瓦斯外泄或燃烧不完全，致瓦斯或一氧化碳含量超过预定值时而自动切断电磁阀的电压，使电磁阀复归闭阀位，截断瓦斯通路，停止供气。此时，若瓦斯器具开关未能及时关闭，电磁阀在电压重新加上的瞬间就会作用成开阀位使瓦斯流通，则因瓦斯器具开关仍保持在ON的状态，结果可能因为瓦斯外泄而发生瓦斯(一氧化碳)中毒，甚至引发爆炸。Here, the solenoid valve is used to open and close the gas passage as an example. Assuming that the gas appliance is in use, due to gas leakage or incomplete combustion, when the gas or carbon monoxide content exceeds the predetermined value, the voltage of the solenoid valve will be automatically cut off, the solenoid valve will return to the closed position, the gas passage will be cut off, and the gas supply will be stopped. At this time, if the switch of the gas appliance fails to close in time, the solenoid valve will act as an open valve to allow the gas to flow at the moment the voltage is reapplied, and the switch of the gas appliance is still in the ON state, and the result may be due to gas leakage. Gas (carbon monoxide) poisoning occurs, and even an explosion occurs.

因此，要求安全启动的电磁阀应具备安全装置。所谓安全装置是要让电磁阀一定要朝安全方向作用，除非将不安全因素用人工确认排除外，绝对不使电磁阀自动开启。Therefore, the solenoid valve that requires safe start should have a safety device. The so-called safety device is to make the solenoid valve act in a safe direction, unless the unsafe factors are manually confirmed and excluded, the solenoid valve will never be automatically opened.

Position; an operating part that moves toward the valve part, includes a second magnetizer, and a second spring keeps the second magnetizer at a position away from the first magnetizer; and is located between the first and second magnetizers A coil used to generate an electromagnetic field. When the current flows through the coil, the second magnetic conductor can be turned into an electromagnet, and when the operation part is pressed by hand, it will attract each other with the first magnetic conductor, and the operation part will be pushed back by the elastic force of the second spring when the hand leaves At the same time, it drives the displacement of the valve part and the coil, so that the valve body moves to the open valve position and opens the fluid passage. When the current is cut off, the valve part returns to its original position through the elastic force of the first spring due to the disappearance of the electromagnetic force, so that the valve body returns to the closed valve position and the fluid passage is blocked.

上述电磁阀又包含一指示灯开关随阀部的运动作『ON』『OFF』动作，使一电性连接指示灯开关的指示灯亮灭，以显示电磁阀的开闭状态。The above-mentioned solenoid valve also includes an indicator light switch that acts "ON" and "OFF" with the movement of the valve part, so that an indicator light electrically connected to the indicator switch is turned on and off to display the open and close state of the solenoid valve.

此外，该电磁阀包含一电源开关随操作部的运动作『ON』『OFF』动作，以接通、切断一控制电路的电源，该控制电路的输出端电性连接该线圈，以供给线圈产生电磁场需要的电流。In addition, the solenoid valve includes a power switch that acts "ON" and "OFF" with the movement of the operating part to connect and cut off the power of a control circuit. The output end of the control circuit is electrically connected to the coil to supply the coil to generate The electric current required by the electromagnetic field.

上述第二弹簧的弹性力大于第一弹簧的弹性力，确保在第一导磁体和第二导磁体相互吸引时，阀体可以完全地打开，不会因为第一弹簧的弹性回复力而复归闭阀位，截断流体通路。The elastic force of the above-mentioned second spring is greater than that of the first spring, ensuring that when the first magnetic conductor and the second magnetic conductor attract each other, the valve body can be fully opened and will not return to close due to the elastic restoring force of the first spring. Valve position, blocking fluid passage.

所述的操作部50包含一梃杆51穿过支架30的杆孔34而支持于第二支持部32向着阀部40滑动，该梃杆51的头部扩大形成一杆头52，并具有一第二导磁体53连结于该梃杆51的尾端，及一第二弹簧54圈套在该梃杆51的外周，该第二弹簧54的两端分别支持于梃杆51的杆头52及支架30的第二支持部32。另外，还有一按钮55安装在梃杆51的杆头52之上，并且突出于壳盖70外供手操作。上述第二导磁体53的外形大致上成倒“E”形；第二弹簧54亦为压缩力发生作用的压力弹簧，  以利用其弹性力将第二导磁体53保持在离开第一导磁体43的位置，而且第二弹簧54的弹性力大于第一弹簧44的弹性力，其作用留待后述。Theoperation part 50 includes atappet 51 passing through therod hole 34 of thebracket 30 and supported by thesecond support part 32 to slide toward thevalve part 40. The head of thetappet 51 is enlarged to form arod head 52, and has a The secondmagnetic conductor 53 is connected to the tail end of thetappet 51, and asecond spring 54 is looped around the outer periphery of thetappet 51, and the two ends of thesecond spring 54 are respectively supported on therod head 52 and the bracket of thetappet 51. 30 of thesecond support portion 32 . In addition, there is abutton 55 mounted on thehead 52 of thetappet 51 and protruding from thecover 70 for manual operation. The profile of the above-mentionedsecond magnetizer 53 is substantially inverted "E" shape; thesecond spring 54 is also a pressure spring with a compressive force, so as to utilize its elastic force to keep thesecond magnetizer 53 away from thefirst magnetizer 43 position, and the elastic force of thesecond spring 54 is greater than the elastic force of thefirst spring 44, and its function will be described later.

所述的线圈60固定在阀部40之上，而介于第一导磁体43和第二导磁体53之间，随着阀部40同步运动，并且电性连接一控制电路(图未示)，使线圈60可从该控制电路获得电流，产生所要的电磁场，相反的电流被切断时，电磁场消失。上述控制电路设置于一固定在支架30侧边的电路板(图未示)之上，用来驱动电磁阀10作『开』或『闭』的动作，其中开启动作必须配合人工操作，其细节同样留待后述，暂且表过。由于控制电路不在本实用新型的讨论范围之内，故进一步说明实无必要。Thecoil 60 is fixed on thevalve part 40, and is interposed between thefirst magnetizer 43 and thesecond magnetizer 53, moves synchronously with thevalve part 40, and is electrically connected to a control circuit (not shown in the figure) , so that thecoil 60 can obtain current from the control circuit to generate the desired electromagnetic field, and when the opposite current is cut off, the electromagnetic field disappears. The above-mentioned control circuit is arranged on a circuit board (not shown) fixed on the side of thebracket 30, and is used to drive thesolenoid valve 10 to "open" or "close". The same is left to be described later, and it will be shown for the time being. Since the control circuit is not within the discussion scope of the present utility model, further explanation is unnecessary.

本实用新型还能通过操作部50的运动去控制一电源开关56作『ON』『OFF』动作，以接通、切断连接至控制电路的电源。在附图的实施例中，该电源开关使用按钮开关，它设置在按钮55的运动路径内，可以因为操作按钮55而被按下，达到接通、切断控制电路电源的目的。The utility model can also control apower switch 56 to perform "ON" and "OFF" actions through the movement of theoperation part 50, so as to connect and cut off the power supply connected to the control circuit. In the embodiment of the drawings, the power switch uses a push button switch, which is arranged in the movement path of thebutton 55 and can be pressed due to the operation of thebutton 55 to achieve the purpose of turning on and off the power supply of the control circuit.

The indicator lights can be made of light emitting diodes.

所述的壳盖70用螺丝29(参见图6)锁紧在壳体20的平台27之上，以保护包括上述支架30、第一导磁体43、操作部50、线圈60、电源开关56、指示灯开关46及控制电路在内的组件。Theshell cover 70 is locked on theplatform 27 of thehousing 20 with screws 29 (see FIG. 6 ), so as to protect the above-mentionedsupport 30,first magnetizer 43, operatingpart 50,coil 60,power switch 56, Components including indicatorlight switch 46 and control circuit.

图3为电磁阀10的动作流程，图4为按下按钮55时电磁阀10的状态，图5为手离开按钮55时电磁阀10的状态。FIG. 3 is the action flow of thesolenoid valve 10 , FIG. 4 is the state of thesolenoid valve 10 when thebutton 55 is pressed, and FIG. 5 is the state of thesolenoid valve 10 when thebutton 55 is released.

按照本实用新型的电磁阀10，按下操作部50的按钮55时，操作部50会向着阀部40移动，同时电源开关56被按钮55压下而接通控制电路的电源，于是从控制电路供给一电压至线圈60，使线圈60通过电流而在四周产生电磁场，将处于该电磁场内的第二导磁体53变成电磁铁，并与第一导磁体43相互吸引。According to thesolenoid valve 10 of the present utility model, when thebutton 55 of the operatingpart 50 is pressed, the operatingpart 50 will move towards thevalve part 40, and thepower switch 56 is pressed by thebutton 55 to turn on the power supply of the control circuit, so the control circuit A voltage is supplied to thecoil 60 to make thecoil 60 generate an electromagnetic field around thecoil 60 , and the secondmagnetic conductor 53 in the electromagnetic field becomes an electromagnet, and attracts the firstmagnetic conductor 43 .

当手离开按钮55时，整个操作部50因第二弹簧54的弹性力而复归原位，同时带动阀部40及线圈60移动，使阀体42作动成开阀位而开启流体通路21。When the hand leaves thebutton 55, theentire operating part 50 returns to its original position due to the elastic force of thesecond spring 54, and at the same time drives thevalve part 40 and thecoil 60 to move, so that thevalve body 42 moves to the valve open position and thefluid passage 21 is opened.

因为第二弹簧54的弹性力大于第一弹簧44的弹性力，故能确保在第一导磁体43被第二导磁体53吸引时，阀体42可以完全地打开，不会因为第一弹簧44的弹性回复力而复归闭阀位，截断流体通路21。当然，如果第一导磁体43和第二导磁体53的相互吸引力大于第一弹簧44的弹性力，则第二弹簧54的弹性力不一定要大于第一弹簧44的弹性力。Because the elastic force of thesecond spring 54 is greater than the elastic force of thefirst spring 44, it can be ensured that when the firstmagnetic conductor 43 is attracted by the secondmagnetic conductor 53, thevalve body 42 can be fully opened, and thevalve body 42 will not be opened due to thefirst spring 44. The elastic restoring force returns to the closed valve position, cutting off thefluid passage 21. Certainly, if the mutual attractive force of thefirst magnetizer 43 and thesecond magnetizer 53 is greater than the elastic force of thefirst spring 44 , the elastic force of thesecond spring 54 does not have to be greater than the elastic force of thefirst spring 44 .

另一方面，当阀部40被电磁力吸引而位移时，连杆45会同时压下指示灯开关46的致动片47使其a接点闭合，因而接通连接至指示灯的电路点亮指示灯，发出一电磁阀10处于开启阀位的视觉信号。On the other hand, when thevalve portion 40 is attracted by the electromagnetic force to displace, the connectingrod 45 will simultaneously depress theactuating plate 47 of the indicatorlight switch 46 to close its a contact, thereby turning on the circuit connected to the indicator light to light the indication. The light sends a visual signal that thesolenoid valve 10 is in the open position.

在电磁阀10作用成开阀位的情形下，有二种方法可以将它关闭。一种是人工操作，一种是自动操作。其中：人工操作是用手再按一次按钮55然后放开，此时控制电路的电源因电源开关56再次被操作而中断，据此切断线圈60的电流，于是阀部40因电磁铁的吸引力消失而被第一弹簧44的弹性力推回原位，使阀体42密着于阀座22而截断流体通路21，同时操作部50因为手离开按钮55而利用第二弹簧54的弹性力复归原位。自动操作是利用控制电路发生作用时，切断线圈60的电流，使阀部40因电磁力消失而藉助第一弹簧43的弹性力复归闭阀位，截断流体通路21。With thesolenoid valve 10 acting in the open position, there are two ways to close it. One is manual operation and the other is automatic operation. Wherein: the manual operation is to press thebutton 55 again by hand and then release it. At this time, the power supply of the control circuit is interrupted because thepower switch 56 is operated again, and the current of thecoil 60 is cut off accordingly, so thevalve part 40 is closed due to the attraction force of the electromagnet. disappears and is pushed back to its original position by the elastic force of thefirst spring 44, so that thevalve body 42 is tightly attached to thevalve seat 22 to block thefluid passage 21, and at the same time, the operatingpart 50 returns to its original position by the elastic force of thesecond spring 54 because the hand leaves thebutton 55. bit. The automatic operation is to cut off the current of thecoil 60 when the control circuit takes effect, so that thevalve part 40 returns to the closed valve position by the elastic force of thefirst spring 43 due to the disappearance of the electromagnetic force, and thefluid passage 21 is blocked.

至于指示灯开关46，不论是人工控制或自动控制，它的a接点在阀部40回复原位时，会因为致动片47被连杆45释放而打开，使指示灯熄灭。As for the indicatorlight switch 46, no matter it is manually controlled or automatically controlled, its a contact will open because theactuating piece 47 is released by the connectingrod 45 when thevalve portion 40 returns to its original position, so that the indicator light is extinguished.

图6和图7显示电磁阀10分别安装于瓦斯调节器90和瓦斯管道95的外观图。6 and 7 show the external views of thesolenoid valve 10 installed on thegas regulator 90 and thegas pipeline 95 respectively.

当然，上述实施例可在不脱离本实用新型的范围内加以若干变化，故以上的说明所包含及附图中所示的全部事项应视为例示性，而非用以限制本实用新型的申请专利范围。Of course, the above-mentioned embodiments can be changed without departing from the scope of the present utility model, so all matters contained in the above description and shown in the accompanying drawings should be regarded as illustrative rather than limiting the application of the present utility model patent scope.
