一、氣動閥門是什么氣動元件

氣(qi)動(dong)閥門(men)就是借助壓縮空氣(qi)驅動(dong)的閥門(men)，是一種常見的氣(qi)動(dong)元(yuan)件，依靠壓縮氣(qi)體來驅動(dong)實際操作(zuo)閥門(men)，其開(kai)閉(bi)速率相對性比較快，主要用于(yu)迅(xun)速二位(wei)斷開(kai)應用，也可以用于(yu)調節閥門(men)應用。

氣動閥門由于(yu)依靠壓縮氣體工(gong)作(zuo)，因此在易燃易爆物(wu)品的(de)場所中(zhong)應(ying)用廣泛，可(ke)用于(yu)控制空氣、水、蒸汽(qi)、各種(zhong)(zhong)腐(fu)蝕性(xing)介質(zhi)、泥漿、油品、液態金屬和放射性(xing)介質(zhi)等各種(zhong)(zhong)類型流體的(de)流動。

二、氣動閥門是什么材質的

氣動(dong)閥(fa)門(men)由(you)閥(fa)體(ti)、閥(fa)桿、螺(luo)母、密封面等部分(fen)組成，不(bu)(bu)同部分(fen)材質有(you)所(suo)不(bu)(bu)同：

1、閥體材(cai)質，以球墨鑄(zhu)鐵為主。

2、閥(fa)(fa)桿(gan)(gan)材質，主要是不(bu)銹(xiu)鋼(gang)閥(fa)(fa)桿(gan)(gan)（2CR13），大口徑閥(fa)(fa)門也應(ying)是不(bu)銹(xiu)鋼(gang)嵌包的閥(fa)(fa)桿(gan)(gan)。

3、螺母材質，采用(yong)鑄(zhu)鋁(lv)黃銅(tong)或(huo)鑄(zhu)鋁(lv)青銅(tong)，且硬度與強度均(jun)大于閥桿。

4、閥桿襯套材質，其硬(ying)度與強度均應(ying)不大于閥桿，且在水浸泡狀(zhuang)況下與閥桿、閥體不形(xing)成電(dian)化(hua)學腐蝕(shi)。

5、密封面的材(cai)質，根據氣動閥門種類(lei)不同，有(you)銅、橡膠(jiao)等(deng)多種。
