參數資料(liao):

3通(tong)氣控閥(fa)介質流動(dong)方向(xiang)應與閥(fa)體箭頭方向(xiang)一致，可(ke)(ke)以(yi)外(wai)接導(dao)壓(ya)管(guan)裝(zhuang)(zhuang)置(zhi)出(chu)(chu)廠(chang)前均通(tong)過壓(ya)力(li)(li)(li)(li)試驗，安(an)裝(zhuang)(zhuang)時(shi)嚴(yan)禁損傷導(dao)壓(ya)裝(zhuang)(zhuang)置(zhi);閥(fa)上的1/2管(guan)接頭應安(an)裝(zhuang)(zhuang)在(zai)水(shui)(shui)泵入口(kou)處;可(ke)(ke)水(shui)(shui)平安(an)裝(zhuang)(zhuang)也可(ke)(ke)以(yi)垂直安(an)裝(zhuang)(zhuang);限流止回閥(fa)的需求揚程大(da)于0.1MPa時(shi)，先逆時(shi)針把四通(tong)開(kai)大(da)，然后再(zai)順時(shi)針逐漸關(guan)閉(bi)調(diao)壓(ya)閥(fa)，關(guan)閉(bi)過程中(zhong)出(chu)(chu)口(kou)壓(ya)力(li)(li)(li)(li)會逐漸增大(da)，直至出(chu)(chu)口(kou)壓(ya)力(li)(li)(li)(li)為需要揚程時(shi)，即完成(cheng)初(chu)調(diao)節，反復啟(qi)閉(bi)水(shui)(shui)泵2-3次(ci)(ci)，每(mei)次(ci)(ci)運行3-5分鐘，出(chu)(chu)口(kou)壓(ya)力(li)(li)(li)(li)不變(bian)即完成(cheng)調(diao)試工作;視(shi)水(shui)(shui)質情況應經常(chang)檢查(cha)出(chu)(chu)口(kou)壓(ya)力(li)(li)(li)(li)值，當出(chu)(chu)口(kou)壓(ya)力(li)(li)(li)(li)小于設定值時(shi)，應開(kai)啟(qi)過濾器排除污物。

按動作(zuo)方(fang)式(shi)(shi)分(fen)類(lei)，可分(fen)為(wei)直動式(shi)(shi)和先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)式(shi)(shi)。直接依靠(kao)(kao)電磁力(li)、氣(qi)壓力(li)、人力(li)和機(ji)械(xie)力(li)使(shi)閥(fa)芯換(huan)向(xiang)的(de)(de)(de)(de)(de)閥(fa)，稱(cheng)(cheng)為(wei)直動式(shi)(shi)換(huan)向(xiang)閥(fa)。直動式(shi)(shi)閥(fa)的(de)(de)(de)(de)(de)通(tong)(tong)徑較小。先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)式(shi)(shi)氣(qi)閥(fa)由先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)閥(fa)和主(zhu)閥(fa)組成(cheng)，依靠(kao)(kao)先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)閥(fa)輸出(chu)的(de)(de)(de)(de)(de)氣(qi)壓力(li)，通(tong)(tong)過控(kong)制(zhi)活(huo)塞等推動主(zhu)閥(fa)芯換(huan)向(xiang)的(de)(de)(de)(de)(de)那部(bu)分(fen)稱(cheng)(cheng)為(wei)主(zhu)閥(fa)。通(tong)(tong)徑大(da)的(de)(de)(de)(de)(de)換(huan)向(xiang)閥(fa)大(da)都為(wei)先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)式(shi)(shi)換(huan)向(xiang)閥(fa)。先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)閥(fa)又分(fen)成(cheng)內部(bu)先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)式(shi)(shi)和外部(bu)先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)式(shi)(shi)。先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)控(kong)制(zhi)的(de)(de)(de)(de)(de)氣(qi)源是主(zhu)閥(fa)提供的(de)(de)(de)(de)(de)為(wei)內部(bu)先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)式(shi)(shi)；先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)控(kong)制(zhi)的(de)(de)(de)(de)(de)氣(qi)源是外部(bu)供給(gei)的(de)(de)(de)(de)(de)為(wei)外部(bu)先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)式(shi)(shi)。外部(bu)先(xian)(xian)(xian)(xian)(xian)導(dao)(dao)式(shi)(shi)換(huan)向(xiang)閥(fa)切換(huan)不受換(huan)向(xiang)閥(fa)使(shi)用(yong)壓力(li)大(da)小的(de)(de)(de)(de)(de)影(ying)響，故換(huan)向(xiang)閥(fa)可在低(di)壓或真空(kong)壓力(li)條件下工作(zuo)。
