Description

Technical Field

[0001] The utility model relates to the technical field of slurry valves, in particular to a hydraulic slurry valve. Background Art

[0002] At present, it is known that in complex places such as mines and coal mines, large pieces of materials need to be crushed into particles of different particle sizes by a mill, and water is used to make the particles into a solution, which is transported by a slurry pump and reaches each process pipeline. The medium in the process pipeline has the characteristic of high flow velocity after being pressurized by the slurry pump. This is because the most important moment for the working of the cut-off valve is the closing moment. At this time, since the effective area enclosed by the gate plate and the valve seat continuously decreases, the flow velocity of the medium continuously increases, and the too fast flow velocity causes serious wear of the valve seat and the gate plate. There is strong wear on the pipeline and the cut-off device. This requires that the valves used in such process pipelines must have the characteristics of long life, easy replacement and maintenance, etc., extend the overhaul time, and reduce the losses caused by shutdown. Generally speaking, at present, knife gate valves are generally used in dusty pipelines in mines, power plants, etc. However, due to the defects of the knife gate valve itself, such as easy leakage and non-wear resistance, the service life is very short, and there are often phenomena such as deposition, blockage and jamming at the closing position when closing, which seriously affects the use effect and life of the valve.
