一、氣動閥門是什么氣動元件

氣(qi)動閥(fa)(fa)門(men)就是(shi)借助壓(ya)縮空(kong)氣(qi)驅動的(de)閥(fa)(fa)門(men)，是(shi)一種(zhong)常見(jian)的(de)氣(qi)動元件，依(yi)靠壓(ya)縮氣(qi)體來驅動實(shi)際操作閥(fa)(fa)門(men)，其開閉速率相對性比較快，主要用(yong)(yong)于迅速二位斷開應用(yong)(yong)，也可以(yi)用(yong)(yong)于調節閥(fa)(fa)門(men)應用(yong)(yong)。

氣動(dong)閥(fa)門由于依靠壓縮氣體工(gong)作，因此在(zai)易燃(ran)易爆物(wu)品的場所(suo)中應用廣泛，可用于控制空氣、水、蒸汽、各種腐蝕性介(jie)質、泥漿、油品、液(ye)態(tai)金屬和放射性介(jie)質等各種類型流體的流動(dong)。

二、氣動閥門是什么材質的

氣動閥門由閥體、閥桿(gan)、螺(luo)母、密封(feng)面等部(bu)分組(zu)成(cheng)，不同部(bu)分材(cai)質(zhi)有(you)所不同：

1、閥體(ti)材質，以(yi)球(qiu)墨鑄鐵為主(zhu)。

2、閥(fa)桿(gan)材質，主要是不(bu)銹(xiu)鋼閥(fa)桿(gan)（2CR13），大口徑(jing)閥(fa)門(men)也應是不(bu)銹(xiu)鋼嵌包(bao)的(de)閥(fa)桿(gan)。

3、螺母(mu)材(cai)質，采(cai)用(yong)鑄(zhu)鋁黃銅或鑄(zhu)鋁青銅，且硬度與強度均大于閥桿。

4、閥(fa)桿襯套材質，其硬(ying)度與(yu)強度均應不大于閥(fa)桿，且在水浸(jin)泡狀況下與(yu)閥(fa)桿、閥(fa)體不形成電(dian)化學(xue)腐蝕。

5、密(mi)封面的材質，根據氣(qi)動閥門種(zhong)類不(bu)同，有銅、橡膠(jiao)等多種(zhong)。
