奧德斯閥門在這給您講一下山東閥門的小知識(shí)，截止閥關(guān)閉后，突面可以只借助物質(zhì)工作壓力來密封性，即只借助物質(zhì)工作壓力將閘閥的突面壓向另一側(cè)的高壓閘閥來確定突面的密封性，這便是自密封。絕大多數(shù)截止閥采用的是強(qiáng)制性封閉的，即閘閥關(guān)閉后，要依靠外力作用強(qiáng)制將閘閥壓向高壓閘閥，來確認(rèn)突面的密閉性。

     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.

　　運(yùn)動(dòng)形式：截止閥的閘閥隨閥座一起作勻速直線運(yùn)動(dòng)的，亦叫消防閘閥。通常是在電動(dòng)推桿上面有梯形螺紋，根據(jù)閘閥頂端螺帽及其油路板里的滑槽，將回轉(zhuǎn)運(yùn)動(dòng)變成勻速直線運(yùn)動(dòng),也就是把實(shí)際操作轉(zhuǎn)距變成實(shí)際操作推動(dòng)力。開始閘閥時(shí)，當(dāng)閘閥起升高度相當(dāng)于閘閥管徑的1：1倍時(shí)，液體通道順暢，但運(yùn)行中，此部位是很難監(jiān)控的。具體使用中，要以閥座的端點(diǎn)做為標(biāo)示，即開不動(dòng)位置，做為它全開位置。為考慮到氣溫變化發(fā)生抱死狀況,一般開到端點(diǎn)位上,再倒回1/2-1圈,做為全開閥門位置。因而,閥門全開位置，按閘閥位置(即行程安排)來決定。有些截止閥閥桿螺母建在閘閥上，主軸旋轉(zhuǎn)推動(dòng)閥座旋轉(zhuǎn)，進(jìn)而閘閥提高，這類閘閥稱為滑動(dòng)塊截止閥或叫暗桿閘閥。

      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.
