-體積小，重量輕
-安裝,拆卸及操作簡易
-方便的手動操作,電動,氣動和液壓自動化操作
-可自動清潔,無需維護(hù)
-完全密封,最大程度保壓
-單件閥桿,不用插銷.
The separation between the flanges should allow free access to the valve with the disk half closed,so the rim is protected and the interference of the elastic rings is reduced during the installation,and the initial value when opening.
法蘭之間的空隙應(yīng)當(dāng)允許閥板半關(guān)閉狀態(tài)的閥門進(jìn)入,這樣 在安裝過程中及初次打開閥門的時候閥座邊緣將被保護(hù)著并且密封圈內(nèi)側(cè)將縮小.
After aligning the valve with the tube flanges,and before tightening the bolts,the disk should be turned until it is completely open.lf it were closed it would twist the ring,so it would expand round the edge of the disk,which woukd create an excessively high torque in the initial opening:it coukd tear or be twisted out of shape permanently.
在調(diào)整好閥門與管道法蘭的位置后及旋緊螺栓之前,閥板應(yīng)置于完全打開位置.如果閥板處于關(guān)閉狀態(tài),密封圈可能被扭曲,擠壓膨脹并包住閥板邊緣,在初次打開造成極大的力矩.閥座可能因此被撕扯.扭曲造成永久性的損害.
Las bridas insuficientemente separadas pueden deteriorar el anillo elastico.if the flanges are not sufficiently separated they could damage the elsdtic ring.
在安裝蹀閥時,如果法蘭未能給予蹀閥充分的空間將會損壞密封圈.
雙偏心閥門的金屬密封在高溫環(huán)境下比橡膠封圈密閉性更好.
