style="text-indent:25px">氣動(dòng)閥門的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止方向流動(dòng)。通常這種閥門是自動(dòng)工作的，在一個(gè)方向流動(dòng)的流體壓力作用下，閥瓣打開；流體反方向流動(dòng)時(shí)，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動(dòng)。其中止回閥就屬于這種類型的閥門，它包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機(jī)構(gòu)，還有一個(gè)像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達(dá)閥座面的合適位置，閥瓣設(shè)計(jì)在鉸鏈機(jī)構(gòu)，以便閥瓣具有足夠有旋啟空間，并使閥瓣真正的、詳細(xì)的與閥座接觸。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。真空氣動(dòng)閥門生產(chǎn)企業(yè)軟密封氣動(dòng)蝶閥密封副由非金屬軟質(zhì)材料對(duì)非金屬軟質(zhì)材料構(gòu)成。</p><div
