style="text-indent:25px">旋啟式止回閥的閥瓣繞轉軸作旋轉運動。其流體阻力一般小于升降式止回閥，它適用于較大口徑的場合。旋啟式止回閥根據(jù)閥瓣的數(shù)目可分為單瓣旋啟式，福建鍛造旋啟止回閥廠家、雙瓣旋啟式及多瓣旋啟式三種。單瓣旋啟式止回閥一般適用于中等口徑的場合。大口徑管路選用單瓣旋啟式止回閥時，福建鍛造旋啟止回閥廠家，為減少水錘壓力，采用能減小水錘壓力的緩閉止回閥。雙瓣旋啟式止回閥適用于大中口徑管路。對夾雙瓣旋啟式止回閥結構小、重量輕，是一種發(fā)展較快的止回閥；多瓣旋啟式止回閥適用于大口徑管路，福建鍛造旋啟止回閥廠家。止回閥又稱單向閥或逆止閥，其作用是防止管路中的介質倒流。福建鍛造旋啟止回閥廠家</p><div

1.產品設計制造按E101和JB/T3595-93標準的規(guī)定，結構合理，性能優(yōu)良，造型2.閥門中腔采用壓力自緊式密封結構，介質壓力越高,密封性能越好。 3.支管兩端為對焊連接，適應不同的接管要求。 4.閥瓣、閥座的密封面采用司太立（stellite）鈷基硬質合金堆焊而成，耐磨、耐高溫，抗擦傷性能好、使用壽命長。電站止回閥工作溫度-29～570℃的石油、化工、火力電站等各種工況的管路上。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
