進(jìn)口氣動截止閥工作原理：

氣動截止閥利用壓縮空氣推動執(zhí)行器內(nèi)多組組合氣動活塞運(yùn)動，傳力給橫梁和內(nèi)曲線軌道的特性，帶動空芯主軸作旋轉(zhuǎn)運(yùn)動，壓縮空氣氣盤輸至各缸，改變進(jìn)出氣位置以改變主軸旋轉(zhuǎn)方向，根據(jù)負(fù)載截止閥所需旋轉(zhuǎn)扭矩的要求，可調(diào)整氣缸組合數(shù)目，帶動負(fù)載截止閥工作。

Working principle of inlet pneumatic stop valve:
The pneumatic stop valve uses compressed air to push multiple groups of combined pneumatic pistons in the actuator to move and transmit force to the crossbeam and inner curve track to drive the hollow spindle to rotate. The compressed air disk is sent to each cylinder to change the inlet and outlet position to change the rotation direction of the spindle. According to the requirements of the rotation torque required by the load stop valve, the number of cylinder combinations can be adjusted to drive the load stop valve The valve works.
                                                                               

進(jìn)口氣動截止閥產(chǎn)品簡介：

進(jìn)口氣動截止閥采用雙作用氣缸，利用上腔進(jìn)氣或者下腔進(jìn)氣來遠(yuǎn)距離控制閥門，操作方便、靈活。氣缸使用介質(zhì)：壓縮空氣，氮?dú)?。結(jié)構(gòu)簡單、制造和維護(hù)方便;工作行程小，啟閉時間短;關(guān)閉體(閥瓣)與閥座密封面采用錐面密封，關(guān)閉力小，耐沖刷，密封可靠。閥座可為更換式閥座，可任意組合與關(guān)閉件密封面材料的配對，以滿足工況要求，延長使用壽命。

Introduction of imported pneumatic stop valve products:
The imported pneumatic cut-off valve adopts double acting cylinder, and uses the upper chamber air intake or lower chamber air intake to remotely control the valve, which is convenient and flexible to operate. Cylinder medium: compressed air, nitrogen. It has the advantages of simple structure, convenient manufacture and maintenance, small working stroke and short opening and closing time, and the sealing surface of the closing body (disc) and the valve seat is sealed with a conical surface, with small closing force, erosion resistance and reliable sealing. The valve seat can be a replaceable valve seat, which can be matched with the sealing surface material of the closing part at will, so as to meet the requirements of working conditions and prolong the service life.
