德國萊克進口法蘭球閥指的是用法蘭連接的不銹鋼球閥，靠旋轉閥來使閥門暢通或閉塞。不銹鋼球閥不易被介質沖蝕，在各行業得到廣泛的應用。我們常見的球閥從材質上,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)、操作前須確認管路和閥已被沖洗過；
2)、閥的操作按執行機構輸入信號大小帶動閥桿旋轉完成：正向旋轉1/4圈(900)時，閥關斷。反向旋轉1/4圈(900)時，閥開啟；
3)、當執行機構方向指示箭頭與管線平行時，閥門為開啟狀態;指示箭頭與管線垂直時，閥門為關閉狀態。
不銹鋼球閥廣泛應用于石油、化工、發電、造紙等各部門，以及人們日常生活中。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.

球閥的種類特點
原文： 球閥有O型球閥和V型球閥之分。O型球閥采用浮動式結構，球芯為精密鑄件，外表鍍硬鉻處理，閥座采用增強聚四氟乙烯材料，流道口與管道 口徑相同，流通能力極大，流阻極小，關閉時無泄漏，一般做開關閥使用，特別適用于高粘度、含纖維、顆粒狀介質；V型球閥采用固定式結 構，球芯上開有V型切口，可實現比例調節，流量特為近似等百分比。 　 根據工藝設備不同可選用氣動或電動執行機構，分別組成氣動球閥 和電動球閥，其中氣動球閥如要實現比例調節須配閥門定位器，電動球閥如要實現比例調節須選電子式電動執行機構或配伺服放大器等。
