一、氣動閥門是什么氣動元件

氣(qi)動(dong)閥(fa)門(men)(men)就是借助(zhu)壓縮空氣(qi)驅(qu)動(dong)的閥(fa)門(men)(men)，是一種常見(jian)的氣(qi)動(dong)元件，依靠壓縮氣(qi)體來驅(qu)動(dong)實際操(cao)作(zuo)閥(fa)門(men)(men)，其開閉速率相對性比較快，主要(yao)用于(yu)迅速二位斷開應用，也可以用于(yu)調節(jie)閥(fa)門(men)(men)應用。

氣動閥(fa)門由于(yu)依靠壓縮(suo)氣體工作，因(yin)此在易(yi)燃易(yi)爆物品(pin)的場(chang)所中應(ying)用(yong)(yong)廣泛，可用(yong)(yong)于(yu)控制(zhi)空氣、水(shui)、蒸汽、各種腐蝕性介質(zhi)、泥漿、油(you)品(pin)、液態金屬和放射性介質(zhi)等(deng)各種類型流體的流動。

二、氣動閥門是什么材質的

氣(qi)動(dong)閥(fa)門由(you)閥(fa)體(ti)、閥(fa)桿、螺母、密封面等(deng)部分(fen)組成，不(bu)同(tong)部分(fen)材質有所不(bu)同(tong)：

1、閥(fa)體(ti)材質(zhi)，以球(qiu)墨鑄鐵為(wei)主。

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

3、螺母材質，采用鑄鋁黃(huang)銅或鑄鋁青(qing)銅，且(qie)硬度(du)與強度(du)均大于閥桿。

4、閥桿(gan)(gan)襯(chen)套材質，其(qi)硬度與(yu)強度均(jun)應(ying)不大(da)于(yu)閥桿(gan)(gan)，且在水浸泡狀況(kuang)下與(yu)閥桿(gan)(gan)、閥體不形(xing)成電化學腐蝕。

5、密封(feng)面(mian)的材質，根(gen)據氣動閥門種(zhong)類不同(tong)，有銅、橡膠等多種(zhong)。
