氣動截止閥

氣動截止閥采用(yong)(yong)雙作(zuo)用(yong)(yong)氣(qi)(qi)(qi)缸(gang)，利用(yong)(yong)上腔(qiang)(qiang)進氣(qi)(qi)(qi)或者下(xia)腔(qiang)(qiang)進氣(qi)(qi)(qi)來遠距離控制閥(fa)門，操作(zuo)方便、靈活。氣(qi)(qi)(qi)缸(gang)使(shi)用(yong)(yong)介(jie)質：壓(ya)縮空(kong)氣(qi)(qi)(qi)，氮氣(qi)(qi)(qi)。結(jie)構簡單、制造和維護方便；工(gong)作(zuo)行程小，啟(qi)閉(bi)時間短；關(guan)(guan)閉(bi)體（閥(fa)瓣）與(yu)(yu)閥(fa)座(zuo)(zuo)密(mi)(mi)封(feng)面(mian)采用(yong)(yong)錐面(mian)密(mi)(mi)封(feng)，關(guan)(guan)閉(bi)力小，耐沖刷，密(mi)(mi)封(feng)可(ke)靠。閥(fa)座(zuo)(zuo)可(ke)為更換式閥(fa)座(zuo)(zuo)，可(ke)任(ren)意組合(he)與(yu)(yu)關(guan)(guan)閉(bi)件密(mi)(mi)封(feng)面(mian)材(cai)料的(de)配對，以滿足工(gong)況要(yao)求，延長使(shi)用(yong)(yong)壽(shou)命(ming).
