一、氣動閥門是什么氣動元件

氣(qi)動閥門(men)就(jiu)是借(jie)助壓縮空氣(qi)驅動的閥門(men)，是一(yi)種常見的氣(qi)動元件，依靠壓縮氣(qi)體來驅動實際操(cao)作閥門(men)，其開(kai)閉速(su)率相對(dui)性比較快，主(zhu)要(yao)用于迅速(su)二位斷開(kai)應用，也(ye)可以(yi)用于調(diao)節閥門(men)應用。

氣動(dong)閥門由于依靠壓縮氣體工(gong)作，因此在(zai)易燃易爆物(wu)品的場所中應(ying)用(yong)廣泛，可(ke)用(yong)于控(kong)制空氣、水、蒸汽、各種(zhong)腐(fu)蝕性介(jie)質、泥漿、油品、液態金(jin)屬和放射性介(jie)質等各種(zhong)類型流(liu)體的流(liu)動(dong)。

二、氣動閥門是什么材質的

氣動(dong)閥(fa)門由閥(fa)體、閥(fa)桿、螺母、密封面等部(bu)分組成，不(bu)同部(bu)分材質(zhi)有所不(bu)同：

1、閥體(ti)材質，以球(qiu)墨鑄鐵為(wei)主。

2、閥桿(gan)(gan)(gan)材質(zhi)，主(zhu)要是不(bu)銹鋼(gang)閥桿(gan)(gan)(gan)（2CR13），大口徑閥門也應是不(bu)銹鋼(gang)嵌包的閥桿(gan)(gan)(gan)。

3、螺(luo)母材質，采用鑄鋁黃銅或鑄鋁青(qing)銅，且硬度與強度均大于閥桿。

4、閥桿(gan)襯(chen)套(tao)材質，其硬度與強度均應不大于(yu)閥桿(gan)，且在水(shui)浸泡狀況下與閥桿(gan)、閥體(ti)不形成(cheng)電(dian)化學腐蝕。

5、密封(feng)面的材質，根(gen)據(ju)氣動閥門(men)種(zhong)類(lei)不(bu)同，有(you)銅、橡膠等多種(zhong)。
