工作原理

气动铸钢硬密封法兰球阀的工作原理是靠旋转阀恋来使阀门畅通或闭塞。球阀开关轻便，体积小，可以做成很大口径，密封可靠，结构简单，维修方便，密封面与球面常在闭合状态，不易被介质冲蚀，在各行业得到广泛的应用。

球阀和旋塞阀是同属一个类型的阀门，只有它的关闭件是个球体，球体绕阀体中心线作旋转来达到开启、关闭的一种阀门。

现实作用

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。球阀是近年来被广泛采用的一种新型阀门，它具有以下优点：

1． 流体阻力小，其阻力系数与同长度的管段相等。

2． 结构简单、体积小、重量轻。

3． 紧密可靠，目前球阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。

4． 操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。

5． 维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。

6． 在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。

7． 适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。

球阀已广泛应用于石油、化工、发电、造纸、原子能、航空、火箭等各部门，以及人们日常生活中。

The working principle of

Working principle of pneumatic steel casting hard sealing flange ball valve is love by rotary valve to keep the valve open or occlusion. Ball valve switch lightweight, small size, can make it big caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries.

Ball valve and plug valve is belong to one type of valve, only its closure is a ball, the ball around the center line of the body as a rotation to achieve a kind of open and close the valve.

Execution standard

1), the product standard

The pipeline ball valve > > 2008 standard

> - 2005

Reality role

Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Ball valve is widely used in recent years a new type of valve, it has the following advantages:

1. The fluid resistance is small, its resistance coefficient with section of equal length.

2. Simple structure, small volume, light weight.

3. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system.

4. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.

5. Easy maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient.

6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric ***lation, medium through, can not cause the valve sealing surface erosion.

7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.

Ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People&＃39;s Daily life.
