德國萊克進口法蘭球閥指的是用法蘭連接的不銹鋼球閥，靠旋轉(zhuǎn)閥來使閥門暢通或閉塞。不銹鋼球閥不易被介質(zhì)沖蝕，在各行業(yè)得到廣泛的應(yīng)用。我們常見的球閥從材質(zhì)上,可以分為:碳鋼球閥,304不銹鋼球閥,316球閥和銅球閥等，下面介紹其操作與使用：
1)、操作前須確認(rèn)管路和閥已被沖洗過；
2)、閥的操作按執(zhí)行機構(gòu)輸入信號大小帶動閥桿旋轉(zhuǎn)完成：正向旋轉(zhuǎn)1/4圈(900)時，閥關(guān)斷。反向旋轉(zhuǎn)1/4圈(900)時，閥開啟；
3)、當(dāng)執(zhí)行機構(gòu)方向指示箭頭與管線平行時，閥門為開啟狀態(tài);指示箭頭與管線垂直時，閥門為關(guān)閉狀態(tài)。
不銹鋼球閥廣泛應(yīng)用于石油、化工、發(fā)電、造紙等各部門，以及人們?nèi)粘Ｉ钪?。法蘭不銹鋼球閥使用步驟。

譯文：

Stainless steel ball valve refers to the stainless steel ball valve with flange connection, by rotating the valve to the valve flow?or?occlusion. Stainless steel ball valve is not easy to be medium erosion, has been widely used in various industries. Our common ball valve from the material, can be divided into: carbon steel ball valve, stainless steel ball valve 304, 316 ball valves and copper ball valve, the following introduces the operation and use of:
1), shall confirm, piping and valves have been washed off before operation;
2), operation of the valve actuator according to the size of the input signal to drive the valve rod to rotate: forward rotation 1/4 ring (900), the valve off. Counter rotating 1/4 ring (900), valve open;
3), when the actuator direction arrow parallel with the pipeline, the valve is open; arrow and the vertical pipe, the valve is closed.
Stainless steel ball valve is widely used in petroleum, chemical, electric power, papermaking and other departments, as well as people's daily life.
