一、氣動閥門是什么氣動元件

氣(qi)動(dong)閥門(men)就是借助(zhu)壓縮(suo)空(kong)氣(qi)驅動(dong)的閥門(men)，是一種常見的氣(qi)動(dong)元件，依靠壓縮(suo)氣(qi)體(ti)來(lai)驅動(dong)實際操作(zuo)閥門(men)，其開閉速(su)率相對性比(bi)較快，主要用(yong)于迅速(su)二位斷開應(ying)(ying)用(yong)，也可以用(yong)于調節(jie)閥門(men)應(ying)(ying)用(yong)。

氣動閥門由(you)于(yu)依(yi)靠壓縮(suo)氣體工作(zuo)，因此在易燃易爆物品(pin)(pin)的場所中應用(yong)廣(guang)泛(fan)，可(ke)用(yong)于(yu)控(kong)制空氣、水、蒸汽、各(ge)種腐蝕(shi)性(xing)介質(zhi)(zhi)、泥漿、油品(pin)(pin)、液態金屬(shu)和放射性(xing)介質(zhi)(zhi)等各(ge)種類型流(liu)體的流(liu)動。

二、氣動閥門是什么材質的

氣動閥(fa)門由閥(fa)體(ti)、閥(fa)桿(gan)、螺母、密封面等部分組成，不同部分材質有所不同：

1、閥(fa)體材質，以(yi)球墨鑄鐵為主。

2、閥(fa)(fa)(fa)桿(gan)材質，主要是(shi)不銹(xiu)鋼閥(fa)(fa)(fa)桿(gan)（2CR13），大(da)口(kou)徑閥(fa)(fa)(fa)門也應是(shi)不銹(xiu)鋼嵌(qian)包的閥(fa)(fa)(fa)桿(gan)。

3、螺母(mu)材質，采用鑄鋁黃銅或鑄鋁青銅，且硬度與強度均(jun)大于閥桿(gan)。

4、閥(fa)桿襯(chen)套材質，其(qi)硬(ying)度與(yu)強度均應不大于閥(fa)桿，且在水浸泡狀況下與(yu)閥(fa)桿、閥(fa)體不形成(cheng)電化學(xue)腐蝕。

5、密封面的(de)材(cai)質，根(gen)據(ju)氣動閥門種(zhong)類(lei)不同，有(you)銅、橡(xiang)膠等(deng)多種(zhong)。
