一、氣動閥門是什么氣動元件

氣(qi)動閥(fa)門就是借助壓縮(suo)空氣(qi)驅動的(de)閥(fa)門，是一種(zhong)常見的(de)氣(qi)動元(yuan)件，依(yi)靠壓縮(suo)氣(qi)體來(lai)驅動實際操作閥(fa)門，其(qi)開(kai)(kai)閉速(su)率相(xiang)對性比較(jiao)快，主要用(yong)于迅速(su)二位斷(duan)開(kai)(kai)應用(yong)，也可以(yi)用(yong)于調節(jie)閥(fa)門應用(yong)。

氣動(dong)閥門由(you)于依靠壓縮氣體工作(zuo)，因此在易燃易爆(bao)物品的場所中(zhong)應用(yong)廣泛，可用(yong)于控制(zhi)空氣、水、蒸汽、各種腐(fu)蝕性(xing)介質、泥漿、油品、液態金(jin)屬和放(fang)射性(xing)介質等各種類(lei)型流體的流動(dong)。

二、氣動閥門是什么材質的

氣(qi)動閥門由閥體、閥桿、螺母、密(mi)封面(mian)等部分組(zu)成，不同(tong)部分材質有所不同(tong)：

1、閥體(ti)材(cai)質，以球墨(mo)鑄鐵為主。

2、閥桿材質(zhi)，主要是(shi)不銹鋼閥桿（2CR13），大口徑閥門也應是(shi)不銹鋼嵌包的閥桿。

3、螺母材質，采用鑄(zhu)鋁(lv)黃(huang)銅或鑄(zhu)鋁(lv)青銅，且硬度與強(qiang)度均(jun)大于閥桿。

4、閥桿(gan)襯(chen)套材質(zhi)，其硬度與強度均應不大(da)于閥桿(gan)，且在水浸泡(pao)狀況(kuang)下與閥桿(gan)、閥體不形成電化學腐蝕。

5、密封面的材質，根據氣動閥門種(zhong)(zhong)類不同(tong)，有銅(tong)、橡(xiang)膠等多種(zhong)(zhong)。
