Ball valve, a valve in which the opening and closing parts (ball) are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid adjustment and control. The hard-sealed V-shaped ball valve has a strong shear force between the V-shaped core and the metal seat of the hard alloy. It is especially suitable for fibers and small solid particles. And other media. The multi-way ball valve on the pipeline can not only flexibly control the confluence, divergence, and flow direction switching of the medium, but also close any channel to connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. According to the driving mode, the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
The characteristics of the ball valve:
Wear resistance: Since the valve core of the hard-sealed ball valve is spray welded with alloy steel, and the sealing ring is 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).
Good sealing performance: Because the sealing of the hard-seal ball valve is manually ground, it cannot be used until the valve core and the sealing ring are in agreement, so its sealing performance is reliable.
Light switch: 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.
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.
