The hard alloy ball is a powder metallurgy product which is sintered in a vacuum furnace or a hydrogen reduction furnace by taking micron-sized powder of carbide WC and TiC of high-hardness refractory metal as main components and cobalt Co or nickel Ni and molybdenum Mo as binders, and the current common hard alloy is YG, YN, YT and YW series.
The common hard alloy ball is mainly used for ball valves, and valves in which a valve body of an opening and closing part is driven by a valve rod and rotates around the axis of the ball valve. The hard seal V-shaped ball valve can also be used for regulating and controlling fluid, wherein a V-shaped ball core of the hard seal V-shaped ball valve and a metal valve seat of the build-up welding hard alloy have strong shearing force, and the hard seal V-shaped ball valve is particularly suitable for media containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on the pipeline, and can close any channel to connect the other two channels. The valve of this type should be generally installed horizontally in the pipeline. The ball valve is divided into: pneumatic ball valves, electric ball valves, manual ball valves.
