内螺纹两片式球阀Q11 不锈钢阀门

Q11F是片式球阀的代号，它和法兰闸阀是同属一个类型的阀门，分为一片式球阀、二片式球阀、三片式球阀等，球体绕阀体中心线作旋转来达到开启、关闭的一种阀门。 球阀在管路中主要用来做切断、分配和改变介质的流动方向。二片式球阀，三片式球阀,是近年来被广泛采用的一种新型阀门。

A、开启过程

B、关闭过程

4手轮转动的后几圈，阀杆底部的角形平面机械地楔向压迫球体，使其紧密地压在阀座上，达到*密封。

Q11F球阀的结构特点：

1、 启闭无摩擦。这一功能完*了传统阀门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，只需配一个小手把阀门就能轻松启闭。

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保证。

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

Female thread two-piece ball valve Q11 stainless steel valve

Q11F is the code name of the piece ball valve. It belongs to the same type of valve as the flange gate valve. It is divided into one-piece ball valve, two-piece ball valve, three-piece ball valve, etc. of a valve. Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Two-piece ball valve and three-piece ball valve are a new type of valve that has been widely used in recent years.

A, the opening process

B, the closing process

4 After several turns of the handwheel rotation, the angular plane at the bottom of the valve stem mechanically wedges the sphere to press the ball tightly, so that it is tightly pressed on the valve seat to achieve complete sealing.

Structural features of Q11F ball valve:

1. Open and close without friction. This function solves the problem of traditional valves affecting the sealing due to friction between the sealing surfaces.

2. Top-loading structure. The valve installed on the pipeline can be directly inspected and maintained online, which can effectively reduce the shutdown of the device and reduce the cost.

3. Single valve seat design. It eliminates the problem that the medium in the cavity of the valve affects the safety of use due to abnormal pressure increase.

4. Low torque design. The valve stem with special structure design can easily open and close the valve with only a small handle.

5. Wedge-shaped sealing structure. The valve is sealed by pressing the ball wedge onto the valve seat by the mechanical force provided by the valve stem, so that the sealing performance of the valve is not affected by the change of the pipeline pressure difference, and the sealing performance is reliably guaranteed under various working conditions.

6. Self-cleaning structure of sealing surface. When the ball is tilted away from the valve seat, the fluid in the pipeline passes evenly along the sealing surface of the ball at 360°, which not only eliminates the local scouring of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning
