進(jìn)口對(duì)夾式超薄型止回閥，超薄型逆止閥慨述 Express with regret

對(duì)夾式超薄型止回閥的閥瓣繞轉(zhuǎn)軸作旋轉(zhuǎn)運(yùn)動(dòng),只允許介質(zhì)向一個(gè)方向流動(dòng),當(dāng)介質(zhì)按規(guī)定方向流動(dòng)時(shí)，閥瓣受介質(zhì)力的作用，被開啟;介質(zhì)逆流時(shí)，因閥瓣自重和閥瓣受介質(zhì)反向力的作用，使閥瓣與閥座的密封面密合而關(guān)閉，達(dá)到阻止介質(zhì)逆流的目的 RETZ The disc of the clip type ultra-thin check valve rotates around the rotation axis, allowing the medium to flow in only one direction. When the medium flows in the specified direction, the disc is opened by the medium force; When the medium is countercurrent, the valve clack is closed due to its dead weight and the reverse force of the medium, which makes the sealing surface of the valve clack and the valve seat close, so as to prevent the medium from countercurrent
