一、氣動閥門是什么氣動元件
氣(qi)動(dong)閥門(men)就是借助壓縮(suo)(suo)空(kong)氣(qi)驅動(dong)的(de)(de)閥門(men),是一(yi)種(zhong)常見的(de)(de)氣(qi)動(dong)元件,依靠(kao)壓縮(suo)(suo)氣(qi)體來驅動(dong)實際(ji)操作(zuo)閥門(men),其開閉(bi)速率相對(dui)性比(bi)較快,主要用(yong)(yong)于迅(xun)速二位(wei)斷開應(ying)用(yong)(yong),也可以用(yong)(yong)于調節閥門(men)應(ying)用(yong)(yong)。
氣動閥門由于依靠壓縮氣體工作,因此在易燃(ran)易爆物品的場所(suo)中應(ying)用(yong)廣(guang)泛,可用(yong)于控(kong)制(zhi)空氣、水、蒸汽、各(ge)種腐(fu)蝕性介質、泥(ni)漿、油(you)品、液(ye)態金屬和放射性介質等(deng)各(ge)種類(lei)型(xing)流(liu)體的流(liu)動。
二、氣動閥門是什么材質的
氣(qi)動(dong)閥(fa)門由閥(fa)體、閥(fa)桿、螺(luo)母、密封(feng)面等部(bu)分(fen)(fen)組成,不同(tong)部(bu)分(fen)(fen)材質有所不同(tong):
1、閥體(ti)材質,以(yi)球墨鑄鐵為主。
2、閥(fa)(fa)桿(gan)材質,主要是(shi)(shi)不(bu)銹鋼閥(fa)(fa)桿(gan)(2CR13),大口徑閥(fa)(fa)門(men)也應是(shi)(shi)不(bu)銹鋼嵌包(bao)的閥(fa)(fa)桿(gan)。
3、螺母(mu)材質,采用鑄(zhu)鋁(lv)黃(huang)銅(tong)或鑄(zhu)鋁(lv)青銅(tong),且硬度與強度均大于閥桿。
4、閥桿襯(chen)套(tao)材質(zhi),其硬度(du)與(yu)(yu)強度(du)均(jun)應不大于閥桿,且在水浸泡(pao)狀況下與(yu)(yu)閥桿、閥體不形成電化(hua)學(xue)腐(fu)蝕。
5、密(mi)封面的(de)材(cai)質,根據氣動閥門(men)種(zhong)類不(bu)同,有銅(tong)、橡膠等多(duo)種(zhong)。
