球阀阀门优点
Advantages of ball valve
1．流体阻力小，全通径的球阀基本没有流阻。  2．结构简单、体积小、重量轻。  3．紧密可靠。它有两个密封面，而且球阀的密封面材料广泛使用各种塑料，密封性好，能实现完全密封。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保定平面设计培训 收费岛模具 挡土墙模具 防撞墙模具 防撞墙模具 防撞护栏模具 大棚遮阳网 遮阴网蚀。  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。  8．由于球阀在启闭过程中有擦拭性，所以可用于带悬浮固体颗粒的介质中。
1. The flow resistance is small, and there is no flow resistance for the full bore ball valve. 2. Simple structure, small volume and light weight. 3. Tight and reliable. It has two sealing surfaces, and the sealing surface material of ball valve is widely used with various plastics, which has good sealing performance and can realize complete sealing. It has been widely used in vacuum system. 4. It is easy to operate and fast to open and close. Only 90 ° rotation is needed from full opening to full closing, which is convenient for remote control. 5. The maintenance is convenient, the ball valve structure is simple, the sealing ring is generally movable, and it is convenient to dismantle and replace. 6. When the valve is fully open or closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and the medium will not cause erosion of the valve sealing surface. 7. Wide range of application, diameter from small to several millimeters, large to several meters, from high vacuum to high pressure. In the process of cleaning, the ball valve can be opened and closed with solids
