一、氣動閥門是什么氣動元件

氣(qi)動(dong)閥門(men)(men)就是(shi)借(jie)助壓(ya)縮空氣(qi)驅動(dong)的閥門(men)(men)，是(shi)一種常見的氣(qi)動(dong)元件，依靠壓(ya)縮氣(qi)體(ti)來驅動(dong)實際操作閥門(men)(men)，其開閉(bi)速(su)率相對性比較快(kuai)，主要(yao)用(yong)于(yu)(yu)迅速(su)二位(wei)斷(duan)開應用(yong)，也(ye)可以用(yong)于(yu)(yu)調節閥門(men)(men)應用(yong)。

氣(qi)(qi)動(dong)閥門由于依靠(kao)壓縮氣(qi)(qi)體(ti)工(gong)作，因此在易燃易爆物(wu)品(pin)的場所中應用廣(guang)泛(fan)，可用于控制(zhi)空氣(qi)(qi)、水、蒸(zheng)汽(qi)、各(ge)種(zhong)腐蝕(shi)性(xing)介(jie)(jie)質(zhi)、泥漿、油品(pin)、液態金屬(shu)和放射性(xing)介(jie)(jie)質(zhi)等各(ge)種(zhong)類型流(liu)體(ti)的流(liu)動(dong)。

二、氣動閥門是什么材質的

氣動閥門(men)由(you)閥體、閥桿、螺母、密封面(mian)等(deng)部分(fen)組成，不同(tong)部分(fen)材(cai)質有所不同(tong)：

1、閥體(ti)材質，以球墨鑄(zhu)鐵為主。

2、閥(fa)桿(gan)(gan)材質，主要是不銹(xiu)鋼閥(fa)桿(gan)(gan)（2CR13），大口徑(jing)閥(fa)門也應是不銹(xiu)鋼嵌包(bao)的閥(fa)桿(gan)(gan)。

3、螺母材質，采用鑄(zhu)鋁(lv)黃(huang)銅(tong)或鑄(zhu)鋁(lv)青(qing)銅(tong)，且硬度與強度均大于閥(fa)桿。

4、閥桿襯套材質，其硬度與強度均應(ying)不(bu)大于閥桿，且在水浸泡狀況下(xia)與閥桿、閥體(ti)不(bu)形(xing)成電(dian)化學(xue)腐蝕。

5、密封面的材(cai)質，根據氣動(dong)閥門種類不(bu)同，有銅、橡(xiang)膠等多(duo)種。
