结构特点

1、 启闭无摩擦。这一功能完全解决了传统[wiki]阀门[/wiki]因密封面之间相互摩擦而影响密封的问题。

2、 上装式结构。对装在管道上的阀门可直接在线检查与维修，能有效减少装置停车，降低成本。

3、 单阀座设计。消除了阀门中腔介质因异常升压而影响使用安全的问题。

4、 低扭矩设计。特殊结构设计的阀杆，只需配一个小手轮阀门就能轻松启闭。

5、 楔形密封结构。阀门是靠阀杆提供的机械力，将球楔压到阀座上而密封，使阀门的密封性不受管线压差变化的影响，在各种工况下密封性能都有可靠***。

6、 密封面的自清洁结构。当球体倾离阀座时，管线中的流体沿球体密封面成360°均匀通过，不仅消除了高速流体对阀座局部的冲刷，也冲走了密封面上的聚积物，达到自清洁的目的。

使用方法

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。

Structural characteristics of

1, the opening and closing without friction. This function completely solve the traditional [wiki] [/ wiki] for valve sealing surface friction and interaction between the sealing problem.

2, the structure of the jacket type. The valve can be directly mounted on the pipeline online inspection and maintenance, can effectively reduce the parking device, reduce the cost.

3, single seat design. To eliminate the influence due to abnormal pressure valve lumen medium use safety problems.

4, low torque design. Special structure design of the valve stem, only with a small hand wheel can be easily opening and closing of the valve.

5, wedge seal structure. Valve by valve stem provides mechanical force, wedge pressure the ball into the seat and seal, make the valve&＃39;s sealing is not affected by changes in the pipeline pressure difference, under various conditions sealed performance has a reliable guarantee.

6, the structure of the sealing surface of self-cleaning. When the ball tilting away from the seat, fluid in the pipeline along the sphere uniform sealing surface into 360 ° through, not only eliminates the high velocity on the seat of local scour, also washed away by the accumulated on the surface of the sealing material, achieve the goal of the clean.

Method of use

1. The operation must be confirmed before piping and valves have been washed.

2. The operation of the valve actuator input signal size turns the valve stem complete: 1/4 turns positive (900), the valve is shut off. Counter-rotating 1/4 round (900), the valve is open.

3. When executing agency indicating arrow direction parallel to the pipeline when the valve is open; Indicating arrow and vertical pipeline, the valve is closed.
