Q944F電動三通球閥
、電動三通球閥 概述
Q944F電動三通球閥是由CHR角行程(cheng)電(dian)(dian)動執行器及(ji)三(san)通(tong)(tong)球(qiu)閥(fa)組成,是種旋轉類切(qie)斷、調節閥(fa)門,具有(you)(you)關閉(bi)嚴密(mi),結(jie)構(gou)緊湊(cou),重量(liang)輕(qing),維修方便等(deng)優點。電(dian)(dian)動三(san)通(tong)(tong)球(qiu)閥(fa)以220V單相(xiang)(xiang)交流(liu)電(dian)(dian)為動力源(yuan),接受控制(zhi)系統的(de)(de)開關信號,通(tong)(tong)過單相(xiang)(xiang)電(dian)(dian)源(yuan)切(qie)換驅動可(ke)逆單相(xiang)(xiang)齒輪(lun)減速(su)機,使(shi)球(qiu)閥(fa)按規定要求對管(guan)路進行切(qie)換。兩閥(fa)座密(mi)封電(dian)(dian)動三(san)通(tong)(tong)球(qiu)閥(fa)具有(you)(you)結(jie)構(gou)緊湊(cou)、外型美觀、密(mi)封性能(neng)好,它能(neng)實現(xian)對管(guan)道中(zhong)介質(zhi)流(liu)向的(de)(de)切(qie)換,也能(neng)使(shi)相(xiang)(xiang)互垂(chui)直的(de)(de)兩個通(tong)(tong)道連通(tong)(tong)或(huo)(huo)關閉(bi)。四閥(fa)座密(mi)封電(dian)(dian)動三(san)通(tong)(tong)球(qiu)閥(fa)具有(you)(you)造型美觀、結(jie)構(gou)緊湊(cou)合理。它不僅(jin)可(ke)實現(xian)介質(zhi)流(liu)向的(de)(de)切(qie)換,也可(ke)使(shi)三(san)個通(tong)(tong)道相(xiang)(xiang)互連通(tong)(tong),現(xian)時也可(ke)關閉(bi)任通(tong)(tong)道,使(shi)另外兩個通(tong)(tong)道連通(tong)(tong),靈活控制(zhi)管(guan)路中(zhong)介質(zhi)的(de)(de)合流(liu)或(huo)(huo)分流(liu)。
二、電動三通球閥 特點
1、結構緊湊、啟閉迅速、流道暢通、流體阻力小。
2、密封性能好:利用四面閥座材料聚四氟乙烯彈性變形實現無泄漏密封。
3、閥多用:任通口可用作入口而無泄漏,三通既可制成L型通口,也可制成T型通口。
4、維修(xiu)(xiu)方便:在系統(tong)卸壓后,無需拆下整個閥體(ti)就可進行檢查和維修(xiu)(xiu)。
