BURKERT不(bu)銹鋼球閥(fa)(fa)(fa)(fa)是具有(you)兩種(zhong)以上流(liu)(liu)動(dong)形式(shi)和兩個以上油(you)口(kou)(kou)的方向(xiang)(xiang)(xiang)(xiang)(xiang)控(kong)制閥(fa)(fa)(fa)(fa)。是實現液(ye)壓油(you)流(liu)(liu)的溝(gou)通(tong)、切斷和換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang),以及壓力卸(xie)載和順序動(dong)作(zuo)(zuo)(zuo)控(kong)制的閥(fa)(fa)(fa)(fa)門。可分為(wei)(wei)手動(dong)換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)、電磁(ci)換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)、電液(ye)換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)等。閥(fa)(fa)(fa)(fa)門的一(yi)種(zhong),具有(you)多向(xiang)(xiang)(xiang)(xiang)(xiang)可調的通(tong)道(dao),可適時改變(bian)流(liu)(liu)體(ti)流(liu)(liu)向(xiang)(xiang)(xiang)(xiang)(xiang)。工(gong)(gong)(gong)作(zuo)(zuo)(zuo)時借(jie)著閥(fa)(fa)(fa)(fa)外的驅(qu)動(dong)傳動(dong)機構轉動(dong)驅(qu)動(dong)軸(zhou),帶動(dong)搖拐臂(bei),啟動(dong)閥(fa)(fa)(fa)(fa)板,使工(gong)(gong)(gong)作(zuo)(zuo)(zuo)流(liu)(liu)體(ti)時而(er)從左入口(kou)(kou)通(tong)向(xiang)(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)的下(xia)(xia)部出(chu)口(kou)(kou),時而(er)人右入口(kou)(kou)變(bian)換(huan)(huan)(huan)通(tong)向(xiang)(xiang)(xiang)(xiang)(xiang)下(xia)(xia)部出(chu)口(kou)(kou),實現了周期變(bian)換(huan)(huan)(huan)流(liu)(liu)向(xiang)(xiang)(xiang)(xiang)(xiang)的目的。這種(zhong)變(bian)換(huan)(huan)(huan)閥(fa)(fa)(fa)(fa)在石(shi)油(you)、化工(gong)(gong)(gong)生產(chan)中(zhong)有(you)著廣泛的應用(yong),在合成氨(an)造氣(qi)系統中(zhong)zui為(wei)(wei)常用(yong)。此外,換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)還可作(zuo)(zuo)(zuo)成閥(fa)(fa)(fa)(fa)瓣(ban)式(shi)的結構,多用(yong)于較小流(liu)(liu)量的場合。工(gong)(gong)(gong)作(zuo)(zuo)(zuo)時只需轉動(dong)手輪通(tong)過閥(fa)(fa)(fa)(fa)瓣(ban)來(lai)變(bian)換(huan)(huan)(huan)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)流(liu)(liu)體(ti)的流(liu)(liu)向(xiang)(xiang)(xiang)(xiang)(xiang)。
BURKERT球閥對于(yu)雙動功能閥:
1)切斷氣(qi)源(yuan),使膜(mo)片(pian)提起(qi),脫離(li)密封面。
2)交叉(cha)拆卸閥(fa)體上(shang)的(de)四顆螺釘(ding),使執行機構與閥(fa)座分離(li),切斷下氣(qi)(qi)缸(gang)(gang)氣(qi)(qi)源,上(shang)氣(qi)(qi)缸(gang)(gang)充氣(qi)(qi),更換(huan)膜片。
3)將下(xia)氣缸(gang)充氣,使膜片收起(qi)。
4)將膜片與閥座上的密(mi)封面(mian)對好,交叉安裝固定螺(luo)釘(ding),反復通氣活(huo)動幾(ji)次。
5)關(guan)閉球閥試漏后(hou),可正常使用。
BURKERT球閥(fa)特點
(1)流體阻力小。
(2)能用于含硬質懸(xuan)浮物(wu)的介(jie)質;由于介(jie)質只與閥(fa)體和隔膜接觸,所以無(wu)需填料函(han),不存(cun)在填料函(han)泄漏問題,對閥(fa)桿部分無(wu)腐(fu)蝕可能。
(3)適(shi)用于(yu)有腐蝕性、粘(zhan)性、漿(jiang)液(ye)介質。
(4)不能用于壓力(li)較高的場合。
