Ball valve (ball valve), the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids, among which the hard-sealed V-shaped ball valve has a strong shear force between its V-shaped ball core and the metal valve seat of surfacing welding carbide, and is especially suitable for fibers and tiny solid particles. etc. medium. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel and 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. Zhejiang Wandekai Fluid Equipment Technology Co., Ltd. will show you what are the characteristics of ball valves?
1. Wear-resisting; since the spool of the hard-sealed ball valve is spray-welded with alloy steel,
The sealing ring is alloy steel surfacing, so the hard-sealed ball valve will not produce too much wear when switching. (It has a hardness factor of 65-70):
2. Good sealing performance; because the seal of the hard-sealed ball valve is manually ground, it cannot be used until the valve core and the sealing ring are completely matched. So his sealing performance is reliable.
3. The switch is light; since the bottom of the sealing ring of the hard-sealed ball valve uses a spring to tightly hug the sealing ring and the valve core, 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, rocket and other departments, as well as in people’s daily life.
Causes and Solutions of Common Faults of Several Valves
A valve is a control component in a fluid delivery system, with functions such as cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control…
