一、氣動閥門是什么氣動元件

氣(qi)(qi)動(dong)(dong)閥(fa)(fa)門(men)就是(shi)借(jie)助壓縮(suo)空氣(qi)(qi)驅動(dong)(dong)的閥(fa)(fa)門(men)，是(shi)一種常(chang)見的氣(qi)(qi)動(dong)(dong)元件，依靠(kao)壓縮(suo)氣(qi)(qi)體來驅動(dong)(dong)實際操(cao)作閥(fa)(fa)門(men)，其(qi)開閉速率相對性(xing)比較(jiao)快(kuai)，主要用(yong)于(yu)迅速二位斷開應(ying)用(yong)，也可以用(yong)于(yu)調(diao)節(jie)閥(fa)(fa)門(men)應(ying)用(yong)。

氣動(dong)閥(fa)門由于(yu)依靠(kao)壓縮氣體(ti)工作，因此在易燃(ran)易爆物(wu)品的場(chang)所中應用廣泛(fan)，可用于(yu)控制(zhi)空氣、水(shui)、蒸(zheng)汽、各種腐蝕性(xing)介質(zhi)(zhi)、泥漿、油品、液(ye)態金屬和放射性(xing)介質(zhi)(zhi)等(deng)各種類型流(liu)體(ti)的流(liu)動(dong)。

二、氣動閥門是什么材質的

氣動(dong)閥(fa)(fa)門(men)由閥(fa)(fa)體(ti)、閥(fa)(fa)桿、螺母、密(mi)封面等部(bu)分組成，不(bu)同(tong)部(bu)分材質有(you)所不(bu)同(tong)：

1、閥體(ti)材質，以球墨(mo)鑄(zhu)鐵(tie)為主。

2、閥桿材質，主要(yao)是不(bu)銹鋼閥桿（2CR13），大口徑(jing)閥門也應是不(bu)銹鋼嵌包的閥桿。

3、螺母材質，采用鑄鋁黃銅或鑄鋁青(qing)銅，且硬度(du)與(yu)強度(du)均大于閥桿。

4、閥(fa)桿襯套材質(zhi)，其硬度(du)與(yu)強度(du)均應(ying)不(bu)大于閥(fa)桿，且在水(shui)浸泡狀況下與(yu)閥(fa)桿、閥(fa)體不(bu)形成電化學(xue)腐蝕。

5、密封(feng)面的材質(zhi)，根據氣(qi)動閥門種類不同(tong)，有銅、橡膠等多種。
