style="text-indent:25px">氣動(dòng)閥門分為:單作用和雙作用氣缸。單作用氣缸帶彈簧復(fù)位功能，所以價(jià)格較貴。彈簧復(fù)位功能的概念:閥門初始狀態(tài)是關(guān)閉的-俗稱“氣開式”，通氣后閥門開啟，如果突然氣源斷掉了，這時(shí)候彈簧復(fù)位功能就起作用了，彈簧復(fù)位會(huì)把閥門關(guān)閉掉。同理，如果閥門初始狀態(tài)是開啟的--俗稱“氣閉式”，通氣后閥門關(guān)閉，如果突然氣源斷掉了，這時(shí)候彈簧復(fù)位會(huì)把閥門打開。單作用氣缸，通常用在那些:強(qiáng)酸，強(qiáng)堿，帶有腐蝕性的液體介質(zhì)，或者有毒氣體。簡單說，就是不能泄露的介質(zhì)，如果泄露會(huì)造成傷亡事故的介質(zhì)。所以單作用氣缸比較貴。雙作用氣缸:閥門無論是開啟還是關(guān)閉都需要?dú)庠?。如果突然氣源斷掉，閥門就保持在那當(dāng)時(shí)的狀態(tài)下，氣源重新連接上以后閥門才能繼續(xù)工作。雙作用氣缸:在對(duì)泄露要求不高的工況下，可以選用雙作用氣缸。氣動(dòng)閥門關(guān)不緊可能是什么問題？上海隔膜氣動(dòng)調(diào)節(jié)閥價(jià)格</p><p
