進口絲扣閘閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進口絲扣閘閥是一個啟閉件閘板，閘板的運動方向與流體方向相垂直，閘閥只能作全開和全關(guān)。閘閥關(guān)閉時，密封面可以只依靠介質(zhì)壓力來密封，即只依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強制密封的，即閥門關(guān)閉時，要依靠外力強行將閘板壓向閥座，以保證密封面的密封性。

Introduction of imported screw thread gate valve products:
The screw thread gate valve imported from German Locke is a gate with opening and closing parts. The movement direction of the gate valve is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed. When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only rely on the medium pressure to press the sealing surface of the gate valve to the seat on the other side to ensure the sealing surface, which is self sealing. Most gate valves are forced to seal, that is, when the valve is closed, the gate should be forced to the valve seat by external force, so as to ensure the tightness of the sealing surface.
