一、氣動閥門是什么氣動元件

氣動(dong)閥門就是借助壓縮(suo)空(kong)氣驅動(dong)的閥門，是一(yi)種常(chang)見(jian)的氣動(dong)元(yuan)件，依靠(kao)壓縮(suo)氣體來驅動(dong)實際操作閥門，其開(kai)閉速(su)率相對(dui)性比(bi)較快(kuai)，主(zhu)要用于迅速(su)二位(wei)斷開(kai)應用，也可以用于調節閥門應用。

氣(qi)動閥門(men)由于(yu)(yu)依靠壓縮氣(qi)體工作(zuo)，因此(ci)在易燃易爆物品的(de)場所中(zhong)應用廣泛，可用于(yu)(yu)控制空氣(qi)、水、蒸(zheng)汽(qi)、各種(zhong)腐蝕性介質、泥漿、油品、液態(tai)金屬和放射性介質等各種(zhong)類型流體的(de)流動。

二、氣動閥門是什么材質的

氣動(dong)閥門由閥體、閥桿、螺母、密封面等部(bu)分(fen)(fen)組成，不同部(bu)分(fen)(fen)材質(zhi)有(you)所(suo)不同：

1、閥(fa)體材質，以球(qiu)墨鑄鐵為主。

2、閥(fa)(fa)桿材質，主要是(shi)不銹鋼閥(fa)(fa)桿（2CR13），大口徑閥(fa)(fa)門(men)也應(ying)是(shi)不銹鋼嵌包的閥(fa)(fa)桿。

3、螺母材質，采用鑄鋁黃銅(tong)或(huo)鑄鋁青銅(tong)，且硬度與強度均大于(yu)閥桿。

4、閥桿(gan)襯套(tao)材質(zhi)，其(qi)硬度與強(qiang)度均(jun)應(ying)不(bu)(bu)大于(yu)閥桿(gan)，且在水浸泡狀況下與閥桿(gan)、閥體不(bu)(bu)形(xing)成(cheng)電化(hua)學(xue)腐蝕(shi)。

5、密封面的材質，根(gen)據氣動閥門(men)種類不同，有銅、橡膠等多種。
