手柄对夹式蝶阀的蝶板安装于管道的直径方向。在蝶阀阀体圆柱形通道内，圆盘形蝶板绕着轴线旋转，旋转角度为0°-90°之间，旋转到90°时，阀门则处全开状态。此阀门一般水平安装。

手柄蝶阀结构简单、体积小、重量轻，只由少数几个零件组成。而且只需旋转90°即可快速启闭，操作简单，同时该阀门具有良好的流体控制特性。蝶阀处于*开启位置时，蝶板厚度是介质流经阀体时仅有的阻力，因此通过该阀门所产生的压力降很小，故具有较好的流量控制特性。蝶阀有弹性密封和金属密封两种密封型式。弹性密封阀门，密封圈可以镶嵌在阀体上或附在蝶板周边。

手柄蝶阀是重点新产品，高性能的手动蝶阀采用了一个双偏心和一个特殊斜锥椭圆密封结构。解决了传统偏心蝶阀在启闭0°～10°瞬间密封面仍处于滑动接触摩擦的弊病，实现蝶板在开启瞬间密封面即分离，关闭接触即密封的效果，达到延长使用寿命、密封性能佳的目的。

手柄对夹式蝶阀结构特点：

1由扭矩产生弹性密封。

2巧妙的楔形设计使阀门有越关越紧的自动密封功能，密封面之间具有补偿性、零泄漏。

3体积小、重量轻、操作轻巧、便于安装。

4宽边浮动式橡胶阀座。

5特殊切向销连接。

6双向等压密封，低水损。

The butterfly plate of the handle wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When it rotates to 90°, the valve is in a fully open state. This valve is generally installed horizontally.

The handle butterfly valve is simple in structure, small in size and light in weight, and only consists of a few parts. And it only needs to rotate 90° to open and close quickly, the operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. Butterfly valve has two types of sealing: elastic seal and metal seal. Elastic sealing valve, the sealing ring can be inlaid on the valve body or attached to the periphery of the disc.

The handle butterfly valve is the key new product. The high-performance manual butterfly valve adopts a double eccentric and a special inclined cone elliptical sealing structure. It solves the disadvantage that the sealing surface of the traditional eccentric butterfly valve is still in sliding contact friction at the moment of opening and closing 0°~10°, and realizes the effect that the sealing surface of the butterfly plate is separated at the moment of opening, and the sealing is effected when the contact is closed, so as to prolong the service life and achieve good sealing performance. the goal of.

Structural features of handle wafer butterfly valve:

1 An elastic seal is produced by torque.

2 The ingenious wedge-shaped design enables the valve to have an automatic sealing function of closing and tightening, with compensation and zero leakage between the sealing surfaces.

3 Small size, light weight, light operation and easy installation.

4 Wide-sided floating rubber seat.

5 Special tangential pin connections.

6 Bidirectional isobaric seal, low water loss.
