氣動角座閥的(de)工作原理，它(ta)是通過氣動執行機構來控制介(jie)質(zhi)的(de)流通與調節，都知道有這樣的(de)作用(yong)，但具體氣動角座閥怎么控制介質流通(tong)？有什么(me)樣的控制方(fang)式，那么(me)就要從閥門(men)(men)的作用特點入手，合(he)理(li)的去選擇(ze)使用適合(he)自己工況的閥門(men)(men)，這樣的閥門(men)(men)才會更加得心應(ying)手，使用壽(shou)命也更長，并且工藝結(jie)構好的操(cao)作方(fang)便(bian)，同樣就節約了很大的成本。

   氣動角座閥(fa)根(gen)據現(xian)場(chang)工況有三種控(kong)制(zhi)方式

   這(zhe)三種控制(zhi)方式有(you)常(chang)開、常(chang)閉(bi)(bi)、雙作用(yong)(yong)(yong)，根據不(bu)同的(de)工(gong)況選擇(ze)合適的(de)控制(zhi)方式，先來看(kan)下常(chang)型，它(ta)適用(yong)(yong)(yong)于(yu)(yu)氣(qi)(qi)(qi)(qi)(qi)動(dong)閥(fa)(fa)工(gong)作時(shi)(shi)間處(chu)(chu)于(yu)(yu)開啟(qi)(qi)時(shi)(shi)間長(chang)(chang)的(de)場(chang)(chang)合，閥(fa)(fa)門(men)(men)處(chu)(chu)于(yu)(yu)常(chang)開時(shi)(shi)彈(dan)簧(huang)(huang)不(bu)負載外加氣(qi)(qi)(qi)(qi)(qi)源(yuan)(yuan)推力(li)，此時(shi)(shi)閥(fa)(fa)門(men)(men)疲(pi)勞(lao)降到很低的(de)時(shi)(shi)候，因為是(shi)靠(kao)氣(qi)(qi)(qi)(qi)(qi)壓關(guan)閉(bi)(bi)閥(fa)(fa)門(men)(men)，所(suo)以(yi)需(xu)要現場(chang)(chang)氣(qi)(qi)(qi)(qi)(qi)壓穩(wen)定，供(gong)氣(qi)(qi)(qi)(qi)(qi)可(ke)(ke)靠(kao)；其次(ci)是(shi)常(chang)閉(bi)(bi)型用(yong)(yong)(yong)戶：適用(yong)(yong)(yong)于(yu)(yu)氣(qi)(qi)(qi)(qi)(qi)動(dong)閥(fa)(fa)工(gong)作時(shi)(shi)間處(chu)(chu)于(yu)(yu)關(guan)閉(bi)(bi)時(shi)(shi)間長(chang)(chang)的(de)場(chang)(chang)合，由于(yu)(yu)依靠(kao)彈(dan)簧(huang)(huang)關(guan)閉(bi)(bi)的(de)，當氣(qi)(qi)(qi)(qi)(qi)源(yuan)(yuan)壓力(li)推動(dong)活塞推開彈(dan)簧(huang)(huang)時(shi)(shi)，閥(fa)(fa)門(men)(men)才打開，所(suo)以(yi)對于(yu)(yu)常(chang)閉(bi)(bi)型用(yong)(yong)(yong)戶，該閥(fa)(fa)門(men)(men)使用(yong)(yong)(yong)壽命更長(chang)(chang)，用(yong)(yong)(yong)氣(qi)(qi)(qi)(qi)(qi)量更節約，同時(shi)(shi)當氣(qi)(qi)(qi)(qi)(qi)源(yuan)(yuan)故障時(shi)(shi)，閥(fa)(fa)門(men)(men)處(chu)(chu)于(yu)(yu)關(guan)閉(bi)(bi)狀態(tai)，此控制(zhi)狀態(tai)用(yong)(yong)(yong)的(de)十分(fen)廣泛。雙作用(yong)(yong)(yong)型用(yong)(yong)(yong)戶：雙作用(yong)(yong)(yong)型指從氣(qi)(qi)(qi)(qi)(qi)缸兩邊(bian)分(fen)別輸入壓縮(suo)空氣(qi)(qi)(qi)(qi)(qi)，以(yi)實現雙向(xiang)運動(dong)，如(ru)果氣(qi)(qi)(qi)(qi)(qi)缸內(nei)沒有(you)彈(dan)簧(huang)(huang)，該閥(fa)(fa)則啟(qi)(qi)閉(bi)(bi)迅速，可(ke)(ke)用(yong)(yong)(yong)于(yu)(yu)大行程閥(fa)(fa)門(men)(men)，也是(shi)靠(kao)氣(qi)(qi)(qi)(qi)(qi)源(yuan)(yuan)壓力(li)關(guan)閉(bi)(bi)閥(fa)(fa)，所(suo)以(yi)需(xu)要現場(chang)(chang)氣(qi)(qi)(qi)(qi)(qi)源(yuan)(yuan)充足穩(wen)定，供(gong)氣(qi)(qi)(qi)(qi)(qi)可(ke)(ke)靠(kao)。
