5.所采用的止回閥應能水平和垂直安裝，其內部設計應達到全流面積以便減少水頭損失及便于讓雜物通過，其主要構件包括閥體、閥體及橡膠閥瓣，其閥體及閥蓋均采用一次鑄造完成，橡膠閥瓣應由NBR橡膠硬化處理，內嵌鋼板及鋼棒以增加強度，其邊緣有一突環(huán)（O型環(huán)）作為封水膠圈，防止低壓時管內水倒流。 6.閥門內外應經(jīng)高壓噴砂除銹處理后（達到Sa2.5級），噴涂環(huán)氧樹脂涂層，厚度大于200μm。所有涂料干后應不溶于水，不影響水質，且不應因空氣、溫度變化而發(fā)生異狀。多瓣旋啟式止回閥適用于大口徑管路。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">電站止回閥常見故障及處理方法：①閥瓣打碎；②介質倒流。引起閥瓣打碎的原因是:止回閥前后介質壓力處于接近，其平衡而又互相“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。預防的辦法是采用閥瓣為韌性材料的止回閥。介質倒流的原因有:①密封面破壞；②夾入雜質。修復密封面和清洗雜質，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倒流。止回閥屬于自動閥類，啟閉件靠流動介質的力量自行開啟或關閉。止回閥只用于介質單向流動的管路上，阻止介質回流，以防發(fā)生事故。山東高溫高壓旋啟止回閥廠家</p><p
