奥德斯阀门在这给您讲一下山东阀门的小知识，截止阀关闭后，突面可以只借助物质工作压力来密封性，即只借助物质工作压力将闸阀的突面压向另一侧的高压闸阀来确定突面的密封性，这便是自密封。绝大多数截止阀采用的是强制性封闭的，即闸阀关闭后，要依靠外力作用强制将闸阀压向高压闸阀，来确认突面的密闭性。

     Odes Valve is here to share with you some knowledge about Shandong valves. After the shut-off valve is closed, the protruding surface can only be sealed with the help of material working pressure, that is, the protruding surface of the gate valve can be pressed towards the high-pressure gate valve on the other side to determine the sealing of the protruding surface, which is self sealing. The vast majority of globe valves adopt mandatory sealing, which means that after the gate valve is closed, external force is used to force the gate valve towards the high-pressure gate valve to confirm the sealing of the protruding surface.

　　运动形式：截止阀的闸阀随阀座一起作匀速直线运动的，亦叫消防闸阀。通常是在电动推杆上面有梯形螺纹，根据闸阀顶端螺帽及其油路板里的滑槽，将回转运动变成匀速直线运动,也就是把实际操作转距变成实际操作推动力。开始闸阀时，当闸阀起升高度相当于闸阀管径的1：1倍时，液体通道顺畅，但运行中，此部位是很难监控的。具体使用中，要以阀座的端点做为标示，即开不动位置，做为它全开位置。为考虑到气温变化发生抱死状况,一般开到端点位上,再倒回1/2-1圈,做为全开阀门位置。因而,阀门全开位置，按闸阀位置(即行程安排)来决定。有些截止阀阀杆螺母建在闸阀上，主轴旋转推动阀座旋转，进而闸阀提高，这类闸阀称为滑动块截止阀或叫暗杆闸阀。

      Movement form: The gate valve of the shut-off valve moves uniformly in a straight line with the valve seat, also known as a fire gate valve. Usually, there is a trapezoidal thread on the electric push rod, which transforms the rotary motion into a uniform linear motion based on the top nut of the gate valve and the sliding groove in its oil circuit plate, that is, the actual operating torque is converted into the actual operating driving force. When starting the gate valve, when the lifting height of the gate valve is 1:1 times the pipe diameter of the gate valve, the liquid channel is smooth, but during operation, this part is difficult to monitor. In specific use, the end point of the valve seat should be used as a mark, that is, the non moving position, as its fully open position. To take into account the lockup situation caused by temperature changes, it is generally opened to the endpoint position and then reversed by 1/2-1 turn as the fully open valve position. Therefore, the fully open position of the valve is determined by the gate valve position (i.e. stroke arrangement). Some stop valve stem nuts are built on the gate valve, and the spindle rotates to push the valve seat to rotate, which in turn raises the gate valve. This type of gate valve is called a sliding block stop valve or a non rising stem gate valve.
