Description
The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. It only needs to be rotated 90 degrees and the torque can be closed tightly. Ball valves are most suitable for use as switches and shut-off valves, V-type ball valves. In addition to the parameters of the pipeline, the electric valve should be specially marked with the environmental conditions used. Since the electric device in the electric valve is an electromechanical device, its use state is greatly affected by its use environment. Under normal conditions, electric ball valves and butterfly valves should be specially placed in the following ring nights.
・Germany standard flange ball valve features （DIN VALVE)
First, wear resistance; since the valve core of the hard seal ball valve is alloy steel spray welding, the seal ring is alloy steel surfacing, so the hard seal ball valve does not cause too much wear when switching. (It has a hardness coefficient of 65-70):
Second, the sealing performance is good: because the sealing of the hard-sealed ball valve is artificial grinding, until the valve core and the sealing ring are completely kissed. Therefore, his sealing performance is reliable.
Third, the switch is light; because the bottom of the sealing ring with a hard seal ball is made of elastic yellow, the sealing cymbal and the valve core are tightly held together, so the switch is very light when the external force exceeds the preload of the yellowing.
4. Long service life: It has been widely used in petroleum, chemical, power generation, papermaking, atomic energy, dirty air, fire reinforcement and other departments, as well as people's daily life.
The pneumatic ball valve is simple and compact in structure, reliable in sealing and convenient in maintenance. The sealing surface and the spherical surface are often in a closed state, which is not easily eroded by the medium, easy to operate and maintain. It is suitable for general working media such as water, solvent, acid and natural gas. The medium in the pipeline can be cut off or turned on, and can also be used for fluid regulation and control.
Compared with other types of valves, pneumatic ball valves have a quarter-turn output torsion torch, which is quick and stable, and is suitable for a wide range of applications.
