德国莱克LIK进口法兰球阀指的是用法兰连接的不锈钢球阀，靠旋转阀来使阀门畅通或闭塞。不锈钢球阀不易被介质冲蚀，在各行业得到广泛的应用。我们常见的球阀从材质上,可以分为:碳钢球阀,304不锈钢球阀,316球阀和铜球阀等，下面介绍其操作与使用：
1)、操作前须确认管路和阀已被冲洗过；
2)、阀的操作按执行机构输入信号大小带动阀杆旋转完成：正向旋转1/4圈(900)时，阀关断。反向旋转1/4圈(900)时，阀开启；
3)、当执行机构方向指示箭头与管线平行时，阀门为开启状态;指示箭头与管线垂直时，阀门为关闭状态。
不锈钢球阀广泛应用于石油、化工、发电、造纸等各部门，以及人们日常生活中。法兰不锈钢球阀使用步骤。
译文：
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 h***e 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.
