進口鑄鋼降式止回閥原理-

RETZ鑄鋼法蘭止回閥當介質(zhì)順規(guī)定方向流動時,閥瓣受介質(zhì)壓力的作用被頂開,實現(xiàn)介質(zhì)的流通,當進口端壓力小于入口端的壓力,依靠閥瓣自身的重量和介質(zhì)反方向流動產(chǎn)生的壓力實現(xiàn)閥瓣的關閉,達到阻止介質(zhì)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.
