一、氣動閥門是什么氣動元件

氣動閥(fa)門就是借助(zhu)壓縮(suo)空氣驅動的閥(fa)門，是一種常見(jian)的氣動元件(jian)，依靠壓縮(suo)氣體來驅動實際(ji)操作閥(fa)門，其(qi)開閉速(su)率相對性(xing)比較快，主要用于(yu)迅速(su)二(er)位斷(duan)開應用，也可以用于(yu)調節閥(fa)門應用。

氣(qi)動(dong)閥(fa)門由于依靠壓縮氣(qi)體(ti)工作(zuo)，因此在易(yi)燃易(yi)爆(bao)物品的(de)場(chang)所中(zhong)應用廣泛，可用于控制空氣(qi)、水、蒸汽、各種腐(fu)蝕性(xing)介(jie)質(zhi)、泥漿、油(you)品、液態金屬和放射性(xing)介(jie)質(zhi)等各種類(lei)型流(liu)體(ti)的(de)流(liu)動(dong)。

二、氣動閥門是什么材質的

氣動閥(fa)門由閥(fa)體、閥(fa)桿、螺(luo)母(mu)、密(mi)封(feng)面等部(bu)(bu)分組成，不同部(bu)(bu)分材質有所不同：

1、閥體(ti)材質，以球墨(mo)鑄鐵(tie)為主。

2、閥(fa)桿材質，主要是不銹鋼閥(fa)桿（2CR13），大(da)口徑閥(fa)門也(ye)應是不銹鋼嵌包的閥(fa)桿。

3、螺母材質，采用鑄(zhu)鋁黃銅(tong)(tong)或鑄(zhu)鋁青(qing)銅(tong)(tong)，且硬度與強度均大(da)于閥桿。

4、閥桿(gan)襯套材質，其硬度與強(qiang)度均應不大于閥桿(gan)，且(qie)在水浸泡(pao)狀況(kuang)下與閥桿(gan)、閥體(ti)不形成電化(hua)學腐蝕。

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