一、氣動閥門是什么氣動元件
氣動閥(fa)門(men)(men)就是借助壓縮空氣驅(qu)動的(de)閥(fa)門(men)(men),是一種(zhong)常見的(de)氣動元件,依靠壓縮氣體來驅(qu)動實際操作(zuo)閥(fa)門(men)(men),其開閉(bi)速率相對(dui)性比較快,主要用(yong)于迅速二(er)位斷開應(ying)用(yong),也可(ke)以用(yong)于調節閥(fa)門(men)(men)應(ying)用(yong)。
氣(qi)動(dong)閥門由于(yu)依靠壓縮氣(qi)體(ti)工作,因此在易(yi)燃易(yi)爆物品的場所(suo)中應用廣(guang)泛,可用于(yu)控制(zhi)空氣(qi)、水(shui)、蒸汽、各種(zhong)腐蝕性介質、泥漿、油品、液(ye)態(tai)金屬和放(fang)射性介質等各種(zhong)類(lei)型流(liu)體(ti)的流(liu)動(dong)。
二、氣動閥門是什么材質的
氣動閥(fa)門由閥(fa)體、閥(fa)桿、螺母、密封面等部分(fen)組(zu)成,不同部分(fen)材質有所不同:
1、閥體材質,以球(qiu)墨鑄鐵為(wei)主。
2、閥(fa)(fa)(fa)桿材質(zhi),主要是不(bu)(bu)銹鋼(gang)(gang)閥(fa)(fa)(fa)桿(2CR13),大口徑(jing)閥(fa)(fa)(fa)門也應是不(bu)(bu)銹鋼(gang)(gang)嵌包的(de)閥(fa)(fa)(fa)桿。
3、螺母材(cai)質,采(cai)用鑄(zhu)(zhu)鋁黃銅(tong)(tong)或(huo)鑄(zhu)(zhu)鋁青銅(tong)(tong),且硬度(du)與(yu)強度(du)均大(da)于閥桿。
4、閥(fa)桿襯套材(cai)質,其硬度與強度均(jun)應不大(da)于(yu)閥(fa)桿,且在(zai)水浸泡狀(zhuang)況下與閥(fa)桿、閥(fa)體不形成電化學(xue)腐蝕。
5、密封(feng)面的材質,根據氣動閥門種類不同,有銅、橡膠(jiao)等多種。
