进口铸钢降式止回阀原理-

RETZ铸钢法兰止回阀当介质顺规定方向流动时,阀瓣受介质压力的作用被顶开,实现介质的流通,当进口端压力小于入口端的压力,依靠阀瓣自身的重量和介质反方向流动产生的压力实现阀瓣的关闭,达到阻止介质倒流的目的。

When the cast steel flange check valve is flowing in the direction of the specified direction, the valve is pushed open by the medium pressure, and the flow of the medium is realized. When the pressure of the inlet is less than the pressure at the entrance, the valve closes by the pressure of the valve's own and the reverse direction of the medium to prevent the reverse flow of the medium.
