一、氣動閥門是什么氣動元件

氣(qi)(qi)動(dong)(dong)閥(fa)門(men)(men)就是借(jie)助壓(ya)縮(suo)空氣(qi)(qi)驅(qu)動(dong)(dong)的閥(fa)門(men)(men)，是一種常見的氣(qi)(qi)動(dong)(dong)元件，依靠(kao)壓(ya)縮(suo)氣(qi)(qi)體來驅(qu)動(dong)(dong)實際(ji)操作閥(fa)門(men)(men)，其開(kai)閉(bi)速率(lv)相對性比較(jiao)快，主要用(yong)于(yu)迅速二位斷開(kai)應用(yong)，也可以用(yong)于(yu)調節(jie)閥(fa)門(men)(men)應用(yong)。

氣(qi)動(dong)閥(fa)門由于依靠壓縮氣(qi)體(ti)工(gong)作，因此在易燃(ran)易爆物品的場所中應用廣泛，可用于控制空氣(qi)、水(shui)、蒸汽、各種(zhong)腐蝕性介(jie)質、泥漿、油品、液(ye)態(tai)金屬和放射(she)性介(jie)質等各種(zhong)類(lei)型流體(ti)的流動(dong)。

二、氣動閥門是什么材質的

氣動閥門由(you)閥體(ti)、閥桿、螺母、密封面等部分組成(cheng)，不(bu)同(tong)部分材質有所不(bu)同(tong)：

1、閥(fa)體材質，以球墨鑄鐵為主(zhu)。

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

3、螺母材質，采用鑄(zhu)鋁黃銅(tong)或鑄(zhu)鋁青銅(tong)，且硬(ying)度與強度均大于閥桿(gan)。

4、閥桿襯套(tao)材質，其硬度(du)與強度(du)均應不大于閥桿，且在(zai)水浸泡(pao)狀況下與閥桿、閥體不形成電化學腐蝕。

5、密封面的材質，根據氣動閥門種類不同，有(you)銅、橡膠(jiao)等多種。
