一、氣動閥門是什么氣動元件

氣(qi)動(dong)(dong)閥(fa)(fa)門就是借助壓縮空氣(qi)驅動(dong)(dong)的閥(fa)(fa)門，是一種常見的氣(qi)動(dong)(dong)元件，依靠壓縮氣(qi)體(ti)來驅動(dong)(dong)實際操作閥(fa)(fa)門，其開(kai)閉速率相對性比較快，主要用于(yu)迅速二位斷開(kai)應(ying)(ying)用，也可以用于(yu)調節(jie)閥(fa)(fa)門應(ying)(ying)用。

氣(qi)(qi)動閥門由于(yu)依靠(kao)壓(ya)縮氣(qi)(qi)體工作，因此在(zai)易(yi)燃(ran)易(yi)爆物品(pin)的場所(suo)中應用廣(guang)泛(fan)，可用于(yu)控制空氣(qi)(qi)、水、蒸汽、各種(zhong)腐蝕性介質(zhi)、泥漿、油(you)品(pin)、液態金屬和放射性介質(zhi)等各種(zhong)類型流體的流動。

二、氣動閥門是什么材質的

氣動閥門由閥體、閥桿、螺(luo)母、密封(feng)面等部分組成(cheng)，不同部分材質有所不同：

1、閥體材質，以(yi)球墨鑄鐵為(wei)主。

2、閥(fa)桿(gan)(gan)(gan)材質(zhi)，主(zhu)要是不銹鋼閥(fa)桿(gan)(gan)(gan)（2CR13），大口徑閥(fa)門也應是不銹鋼嵌包的閥(fa)桿(gan)(gan)(gan)。

3、螺母材質，采用鑄鋁黃銅(tong)或鑄鋁青銅(tong)，且硬(ying)度與(yu)強度均大(da)于(yu)閥桿。

4、閥桿(gan)襯套材質，其(qi)硬度(du)(du)與強度(du)(du)均應不(bu)大于閥桿(gan)，且在水浸泡狀況下與閥桿(gan)、閥體不(bu)形成電化學腐(fu)蝕。

5、密封(feng)面的材(cai)質，根(gen)據氣動閥門(men)種類(lei)不(bu)同，有銅、橡膠(jiao)等多種。
