貫流式止回閥GLH41W說明:
貫流式止回閥GLH41W-16P/25P通過閥門進(jìn)口端與出口端得壓力差來決定閥瓣的開啟和關(guān)閉。當(dāng)進(jìn)口端壓力大于出口端得壓力與彈簧力的總和時,閥瓣開啟。只要有壓力差存在,閥瓣就一直處于開啟狀態(tài),但開啟度有壓力差的大小決定。軸流式止回閥ZLH41W-16P/25P當(dāng)出口端壓力與彈簧力的總和大于進(jìn)口端壓力時,閥瓣則關(guān)閉并一直處于關(guān)閉狀態(tài)。由于閥瓣的開啟與關(guān)閉時是處于一個動態(tài)的力平衡系統(tǒng)中,因此閥門運(yùn)行平穩(wěn),無噪音,水錘現(xiàn)象大大減少。
