style="text-indent:25px">閥瓣可以全部用金屬制成，也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面，這取決于使用性能的要求。旋啟式止回閥在完全打開(kāi)的狀況***體壓力幾乎不受阻礙，因此通過(guò)閥門(mén)的壓力降相對(duì)較小。升降式止回閥的閥瓣座落位于閥體上閥座密封面上。此閥門(mén)除了閥瓣可以自由地升降之外，其余部分如同截止閥一樣，流體壓力使閥瓣從閥座密封面上抬起，介質(zhì)回流導(dǎo)致閥瓣回落到閥座上，并切斷流動(dòng)。根據(jù)使用條件，閥瓣可以是全金屬結(jié)構(gòu)，也可以是在閥瓣架上鑲嵌橡膠墊或橡膠環(huán)的形式。</p><p>

閥門(mén)的主要零件個(gè)數(shù)不多，結(jié)構(gòu)相對(duì)簡(jiǎn)單，大部分尺寸的加工精度不高，外部比較粗糙，這就給人一種屬于簡(jiǎn)單機(jī)械的印象。其實(shí)閥門(mén)的心臟密封部位可是極其精密的，其密封面的"三度"(平整度、光潔度、硬度)要求很高，以及兩個(gè)密封面組成的密封副的吻合度都要達(dá)到零對(duì)零，才能滿足氣密試驗(yàn)的零泄漏。這種以粗糙的基準(zhǔn)來(lái)保證心臟部位精密的零對(duì)零要求，就是閥門(mén)加工的比較大工藝難點(diǎn)。<span
