一、氣動閥門是什么氣動元件

氣動(dong)(dong)閥(fa)(fa)門(men)(men)就是借助(zhu)壓(ya)縮(suo)空(kong)氣驅(qu)動(dong)(dong)的閥(fa)(fa)門(men)(men)，是一種(zhong)常見的氣動(dong)(dong)元件(jian)，依靠壓(ya)縮(suo)氣體來驅(qu)動(dong)(dong)實(shi)際操作閥(fa)(fa)門(men)(men)，其開閉(bi)速率相對性比較快(kuai)，主要用于迅速二位斷開應(ying)用，也可以用于調(diao)節閥(fa)(fa)門(men)(men)應(ying)用。

氣(qi)(qi)動閥門(men)由于依靠壓縮氣(qi)(qi)體(ti)工作，因此在易燃易爆物品的(de)(de)場(chang)所中應用廣泛，可用于控制空(kong)氣(qi)(qi)、水、蒸汽(qi)、各(ge)(ge)種腐蝕性(xing)介(jie)質、泥漿、油(you)品、液態金(jin)屬和放射(she)性(xing)介(jie)質等各(ge)(ge)種類型(xing)流體(ti)的(de)(de)流動。

二、氣動閥門是什么材質的

氣動閥(fa)門(men)由閥(fa)體、閥(fa)桿、螺母、密封(feng)面(mian)等部分(fen)組成(cheng)，不同部分(fen)材質有所不同：

1、閥(fa)體材質，以球墨鑄鐵為主。

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

3、螺母材質(zhi)，采用(yong)鑄(zhu)(zhu)鋁黃銅或鑄(zhu)(zhu)鋁青銅，且硬度與強度均大(da)于閥桿。

4、閥桿襯套材質(zhi)，其硬度與強(qiang)度均應不大(da)于閥桿，且在水浸泡狀(zhuang)況下與閥桿、閥體不形成電(dian)化學腐蝕。

5、密封面的材質，根據氣動閥(fa)門種類不同，有銅、橡(xiang)膠等多(duo)種。
