What is a ball valve? Many consumers must be confused when they see the title. In fact, ball valves are closely related to our lives. Among the structural components of water purifiers that consumers usually use at home, there is the component of a ball valve. Below, the editor will tell you what a ball valve is and what its advantages are.
What is a ball valve
The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. It only needs to be operated with a 90-degree rotation and a small torque to close tightly. The ball valve is most suitable for on-off and shut-off valves, v-type ball valve. In addition to paying attention to pipeline parameters, electric valves should pay special attention to the environmental conditions of their use. 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.
Introduction to the characteristics of ball valves
Wear resistance: Since the valve core of the hard seal ball valve is alloy steel spray welding, the sealing ring is alloy steel surfacing welding, so the hard seal ball valve will not cause too much wear when switching. (Its hardness coefficient is 65-70)
Good sealing performance: Because the seal of hard seal ball valve is manually ground, it can not be used until the valve core and the sealing ring are completely matched. Therefore, his sealing performance is reliable.
Light switch: Because the bottom of the seal ring of the hard seal ball valve uses a spring to tightly hold the seal ring and the valve core, the switch is very light when the external force exceeds the preload of the spring.
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 lives.
Easy to operate and use: Pneumatic ball valve is compact in structure, reliable in sealing, simple in structure, convenient in maintenance, the sealing surface and the spherical surface are often in a closed state, not easy to be eroded by the medium, easy to operate and maintain, suitable for water, solvent, acid and natural gas etc. The working medium is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control.
