②介質(zhì)倒流。引起閥瓣打碎的原因是:止回閥前后介質(zhì)壓力處于接近的平衡而又互相“拉鋸”的狀態(tài)，閥瓣經(jīng)常與閥座拍打，某些脆性材料（如鑄鐵、黃銅等）做成的閥瓣就被打碎。預(yù)防的辦法是采用閥瓣為韌性材料的止回閥。介質(zhì)倒流的原因有:①密封面破壞；②夾入雜質(zhì)。修復(fù)密封面和清洗雜質(zhì)，就能防止倒流。雙旋啟動式止回閥止回閥用途及特性:旋啟式止回閥的功能是用來防止管路中的介質(zhì)倒流。止回閥屬于自動閥類，啟閉件靠流動介質(zhì)的力量自行開啟或關(guān)閉。止回閥只用于介質(zhì)單向流動的管路上，阻止介質(zhì)回流，以防發(fā)生事故。電站止回閥焊接連接的止回閥適用于公稱壓力PN20.0～32.0MPa。河南自密封旋啟止回閥生產(chǎn)廠家</p><p
