According to the requirements of the working conditions, different valves have different uses and characteristics. Solenoid valve products in the process of regulating the flow of the media, the main seal, strength, regulation, opening and closing, circulation and other properties. The ball valve as a kind of solenoid valve, in accordance with the drive can be divided into: pneumatic ball valve, electric ball valve, manual ball valve.
In the use of the project, the ball valve is most suitable for switching, cutting and changing the flow of media to use, it only needs to rotate 90 degrees of operation and a small torque can be turned off. In the purchase of the ball valve at the same time, in addition to the need to consider the ball valve working pressure, media characteristics, temperature and performance and other basic parameters, we also need to know what the advantages and disadvantages of the ball valve?
The advantages of the ball valve:
1. Simple structure, small size, light weight.
2. The fluid resistance is small, the full diameter of the ball valve is basically no resistance.
3. Good sealing performance. The ball valve has two sealing surfaces, and the seal of the hard seal ball valve is manually ground until the spool and seal are fully fit to use. Like corrosion-resistant ball valve, the valve body cavity will be widely used in a variety of plastic, sealing performance, in a vacuum environment has also been widely used.
4. Easy to operate. As a switch, cut off or change the flow of the valve, the ball valve in use only need to rotate 90 degrees, and the torque is small.
5. Scope of application and wide range of applications. Ball valve diameter from small to a few millimeters, large to a few meters, from the real high to high pressure can be used. Moreover, in the field of petroleum, chemical, power generation, papermaking, atomic energy, aviation, rocket, ball valve has been widely used.
So, as such a wide range of applications, easy to use products, what are the limitations?
1. The product is expensive. Because the process of processing precision requirements, which means to put more production energy and resources, so the cost of the ball is more expensive.
2. High temperature should not be used, such as impurities in the pipeline, easily blocked by impurities, resulting in the valve can not open.
