进口气动球阀特点及用途

Features and uses of imported pneumatic ball valves

进口气动球阀主要用于截断或接通管路中的介质，亦可用用于流体的调节与控制，它与其它阀类相比，具有以下一些优点。

The imported pneumatic ball valve is mainly used to cut off or connect the medium in the pipeline, and it can also be used for the regulation and control of fluid. Compared with other valves, it has the following advantages.

1、流体阻力小、球阀是所有阀类中流体阻力最小的一种，即使是缩径球阀，其流体阻力也相当小。

1, the fluid resistance is small, the ball valve is the least fluid resistance in all types of valves, even if the ball valve, its fluid resistance is very small.

2、止推轴承减小阀杆磨擦力矩，可使阀杆长期操作平稳灵活。

2, the thrust bearing reduces the friction torque of the stem, which can make the valve stem operate smoothly and flexibly.

3、阀座密封性能好，采用聚四氟乙烯等弹性材料制成的密封圈，结构易于密封，而且球阀的阀封能力随着介质压力的增高而增大。

3, the valve seat seal performance is good, uses the polytetrafluoroethylene and other elastic materials to make the sealing ring, the structure is easy to seal, and the ball valve sealing ability increases as the medium pressure increases.

4、阀杆密封可靠，由于阀杆只作彷转动运而不做升降运动，阀杆的填料密封不易破坏，且密封能力随着介质的压力增高而增大。

4, the valve stem seal is reliable, because the stem only for imitation rotation transported without movement, stem packing seal is not easy to damage, and sealing ability increased with the increase of the pressure medium.

5、由于聚四氟乙烯等材料具有良好的自润滑性，与球体的磨擦损失小，故球阀的使用寿命长。

5. As the material of polytetrafluoroethylene has good self lubrication and the friction loss of the ball is small, the service life of the ball valve is long.

6、下装式阀杆和阀杆头部凸阶防止阀杆喷出，如火灾造成阀杆密封破坏，凸阶与阀体间还可形成金属接触，确保阀杆密封。

6, downloading the stem and the stem head convex order to prevent the stem spray, such as stem seal damage caused by fire, convex order and the body can be formed between the metal contact, to ensure that the valve stem seals.

7、 防静电功能：在球体、阀杆、阀体之间设置弹簧，能将开关过程产生的静电导出。

7. Antistatic function: the spring is set between the ball, the valve stem and the valve body, which can produce the static electricity produced by the switch process.
