The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small torque can be closed tightly. The ball valve is most suitable for use as a switch and shut-off valve, V-shaped ball valve. In addition to paying attention to the pipeline parameters, electric valves should also pay special attention to the environmental conditions in which they are used. Since the electric device in the electric valve is an electromechanical device, its use status is greatly affected by its use environment. Under normal conditions, special attention should be paid to the use of electric ball valves and butterfly valves in the following environments
1. Wear-resistant; because the valve core of the hard-sealed ball valve is spray-welded with alloy steel, and the sealing ring is surfacing welded with alloy steel, the hard-sealed ball valve will not produce too much wear when it is switched on and off. (Its hardness coefficient is 65-70):
Second, the sealing performance is good; because the sealing of the hard-sealed ball valve is manually ground, it can not be used until the valve core and the sealing ring are completely matched. Therefore, its sealing performance is reliable.
3. The switch is light; since the bottom of the sealing ring of the hard-sealed ball valve adopts a spring to make the sealing ring and the valve core tightly hug together, the switch is very light when the external force exceeds the pre-tightening force of the spring.
4. Long service life: It has been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as people's daily life.
