氣動閘閥

 

Z641系列氣動帶手動楔式閘閥是具有氣動執(zhí)行機構(gòu)(雙層氣缸,并帶有緩沖機構(gòu))和手動及其保護(hù)機構(gòu)(手動和可自鎖的氣動-手動轉(zhuǎn)換裝置)的低支架明桿閘閥。該閥門由于采用雙層氣缸結(jié)構(gòu),其與單氣缸式氣動閘閥相比,提升力增大了一倍。這就從根本上解決了單氣缸氣動閘閥的某些閥體內(nèi)楔死而打不開的弊病。而且,由于該閥具備緩沖機構(gòu),能有效地減速輕了關(guān)閉閥門時,由于活塞下行沖擊而造成的閥板車密封面和閥體密封面的磨損,同時,也能避免閘板卡死的現(xiàn)象。
為了配合用戶實現(xiàn)操作自動化,本公司除供應(yīng)本系列產(chǎn)品之外,還可單獨提供包括支架在內(nèi)的氣缸體,幫助用戶對已有的種類繁多的手動閘閥進(jìn)行改造,將雙缸氣動執(zhí)行機構(gòu)部分安裝在手動閘閥的閥體大蓋上,即可構(gòu)成雙缸式氣動-手動兩用閘閥。
由于其技術(shù)*,性能可靠,操作切換和維修方便,已被石油、化工、冶金、電力、海運等部門作為輸送氣體、液體介質(zhì)的管道開閉裝置而廣泛使用。


主要性能參數(shù)
公稱壓力:1.6,2.5.4.0.6.4MPa
使用溫度:-29~425℃(碳鋼)-40~+550℃(不銹鋼)
公稱通徑:DN50~800mm
閥體材質(zhì):304.306.316L.WCB.HT200
連接法蘭:JB/T79.GB913.HG20592
適用介質(zhì):空氣、水、蒸汽、油及硝酸、醋酸等腐蝕性流體
作用方式:切斷型,調(diào)節(jié)型,手動控制
電源電壓:220VAC、24VAC
輸入信號:4~20mA/1~5VDC
0~20mA/0~10VDC

結(jié)構(gòu)特點
1、 本閥主要由閥體、閥蓋、閘板、閥桿、密封圈、雙層氣缸及其活塞、活塞桿、隔板連同緩沖機構(gòu)、手動機構(gòu)、氣動-手動轉(zhuǎn)換裝置和閥蓋填料裝置等部分組成。
2、上活塞行至行程上端可頂上上回訊器,使之發(fā)訊;下活塞行之行程下端可頂下下回訊器,使之發(fā)訊,以作為閘閥開閉信息在*操作室的模擬儀表盤上進(jìn)行顯示。
3、手輪上部的外伸指示桿的上升和下降,標(biāo)志著該閥的閘板是處于提升狀態(tài)還是下降狀態(tài)。閘閥關(guān)閉時,外伸指示桿位于zui低位置;反之,閘閥全開時,外伸指示桿位于zui高位置。此即為本閥啟閉狀態(tài)的現(xiàn)場指示。
4、氣缸蓋上部裝有氣動-手動轉(zhuǎn)換裝置。將轉(zhuǎn)換手柄順時針方向提轉(zhuǎn)到“氣動”定位孔定位,閘閥處于氣動操作狀態(tài);反之,將轉(zhuǎn)換手柄逆時針方向提轉(zhuǎn)到“手動”定于孔處定位,閘閥即可進(jìn)行手動操作。帶錐齒輪的手柄轉(zhuǎn)換方向相反。手動操作閘閥時,手輪旋向和普通手動閥一樣,即順時針轉(zhuǎn)為關(guān),逆時針轉(zhuǎn)為開。帶錐齒輪轉(zhuǎn)動的相反。
