立式止回阀

立式止回阀】是止回阀旗下产品,我们可为客户提供相关立式止回阀、标准、作用、结构图、规格、型号、外形尺寸、工作原理、说明书、欢迎来电咨询、采购。

  立式止回阀的阀瓣是沿着阀体垂直中心线滑动,当进口端有压力作用,便克服弹簧阻力使阀门开启,当止回阀进口端的压力低于出口端,弹簧将阀芯推向阀座而使阀门关闭,阻止介质逆流,起到止回的作用。

  The Valve Disc Of Vertical Check Valve Slides Along The Vertical Center Line Of The Valve Body. When The Pressure At The Inlet End Is Affected By Pressure, It Overcomes The Spring Resistance And Makes The Valve Open. When The Pressure At The Inlet End Of The Check Valve Is Lower Than That At The Outlet End, The Spring Pushes The Valve Core To The Valve Seat To Close The Valve, Thus Preventing The Reverse Flow Of Medium And Playing A Check Role.
