旋啟式止回閥的閥瓣繞轉(zhuǎn)軸作旋轉(zhuǎn)運(yùn)動(dòng)。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(chǎng)合。旋啟式止回閥根據(jù)閥瓣的數(shù)目可分為單瓣旋啟式、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(chǎng)合。大口徑管路選用單瓣旋啟式止回閥時(shí)，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(duì)夾雙瓣旋啟式止回閥結(jié)構(gòu)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。蝶式止回閥的結(jié)構(gòu)類似于蝶閥。其結(jié)構(gòu)簡(jiǎn)單、流阻較小，水錘壓力亦較小。隔膜式止回閥有多種結(jié)構(gòu)形式，均采用隔膜作為啟閉件，由于其防水錘性能好，結(jié)構(gòu)簡(jiǎn)單，成本低，近年來發(fā)展較快。但隔膜式止回閥的使用溫度和壓力受到隔膜材料的限制。止回閥(CheckValve)：標(biāo)準(zhǔn)旋啟式止回閥煙道止回閥貫流式止回閥對(duì)夾式止回閥緩閉止回閥立式止回閥靜音止回閥止回閥價(jià)格微阻緩閉止回閥H76型對(duì)夾式雙瓣旋啟式止回閥水錘壓力小，閥瓣行程短、且有彈簧輔助關(guān)閉、關(guān)閥速度快H44型法蘭單瓣旋啟止回閥很大，廣東閘閥，閥瓣行程長(zhǎng)，閘閥型號(hào)，需要較長(zhǎng)的關(guān)閉時(shí)間H76型的水錘壓力只有H44型的1/2~1/5球型污水止回閥：閥體采用全通道結(jié)構(gòu)。</p></p><br
