一、氣動閥門是什么氣動元件

氣(qi)動(dong)閥門就是借助壓(ya)縮空(kong)氣(qi)驅動(dong)的(de)閥門，是一種(zhong)常見的(de)氣(qi)動(dong)元件，依靠壓(ya)縮氣(qi)體(ti)來驅動(dong)實際操作閥門，其(qi)開閉速率相對性比(bi)較快，主要用于迅速二(er)位(wei)斷(duan)開應用，也可以用于調節(jie)閥門應用。

氣動閥門由(you)于依靠壓(ya)縮氣體工作，因此在易燃易爆物品的場所(suo)中(zhong)應用(yong)廣(guang)泛，可用(yong)于控制空氣、水、蒸汽、各(ge)(ge)種腐蝕性(xing)介(jie)質、泥(ni)漿、油品、液態金屬和放射(she)性(xing)介(jie)質等(deng)各(ge)(ge)種類(lei)型流體的流動。

二、氣動閥門是什么材質的

氣動閥(fa)門由閥(fa)體、閥(fa)桿(gan)、螺母(mu)、密(mi)封面等部分(fen)組成，不(bu)同部分(fen)材質有所不(bu)同：

1、閥體(ti)材質(zhi)，以球墨鑄鐵為主。

2、閥桿(gan)材質，主要是(shi)不銹(xiu)鋼(gang)(gang)閥桿(gan)（2CR13），大口(kou)徑閥門也應是(shi)不銹(xiu)鋼(gang)(gang)嵌包的閥桿(gan)。

3、螺(luo)母材(cai)質，采用鑄鋁(lv)黃(huang)銅或鑄鋁(lv)青銅，且硬度與強度均大于閥(fa)桿。

4、閥(fa)桿襯套材(cai)質，其(qi)硬度與強(qiang)度均應不大于閥(fa)桿，且在(zai)水浸泡狀況下(xia)與閥(fa)桿、閥(fa)體不形成電化學腐蝕。

5、密封面的材質，根據氣(qi)動閥門種類不同，有銅、橡膠等多(duo)種。
