快闭止回阀

快闭止回阀】是止回阀旗下产品,我们可为客户提供相关快闭止回阀、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。

  快闭式止回阀阀体内设阀座、阀杆、弹簧、阀瓣、导套等零件组成。开泵时,阀瓣在水底推力下上升,开启阀门,同时弹簧被簧力的作用下迅速关闭,当水流接近于0时,阀瓣完全关闭。无水倒流现象,同时因水不能倒流,不产生动能,便防止了水锤的产生。

  The Quick Closing Check Valve Body Is Composed Of Valve Seat, Stem, Spring, Disc, Guide Sleeve And Other Parts. When Starting The Pump, The Valve Disc Rises Under The Water Bottom Thrust And Opens The Valve. At The Same Time, The Spring Is Quickly Closed By The Spring Force. When The Water Flow Is Close To 0, The Valve Disc Is Completely Closed. There Is No Water Backflow Phenomenon. At The Same Time, The Water Hammer Is Prevented Because The Water Cannot Flow Back And Does Not Generate Kinetic Energy.
