High-pressure ceramic slag discharge slurry valves generally have three driving modes: manual, electric and bevel gear transmission. The electric valve is directly driven by electricity to open and close the valve, and can achieve remote control. The manual method is directly driven by the handwheel to open and close the valve. It is simple to operate and does not allow electric control cabinets and pneumatic cylinders. The purchase cost is low and it is suitable for power plant ash removal systems where the temperature and pressure are high. in the piping system. The valve adopts double-sided sealing to achieve double-sided wear resistance. The flushing and flowing parts of the inner cavity are lined with ceramic sheets. The sealing of the valve closing part is formed by the specific pressure generated by the medium pressure difference. The inner diameter of the valve seat ceramic sealing ring has a protective lip (patented) structure, which can effectively prevent hard objects from shearing the ceramic sealing ring from the inner diameter when the valve is about to close. The bevel gear transmission valve adopts double-sided sealing to achieve double-sided wear resistance. The flushing and flowing parts of the inner cavity are lined with ceramic sheets. The sealing of the valve closing part is formed by the specific pressure generated by the medium pressure difference; the valve seat ceramic sealing ring The inner diameter has a protective lip (patented) structure, which can effectively prevent hard objects from shearing the ceramic sealing ring from the inner diameter when the valve is about to close. This series of products are widely used in: 1. Washing and beneficiation - used for high-pressure remote transportation of mineral materials and slurry pipelines 2. Alumina - used for high-pressure pump transportation of mineral materials and slurry pipelines 3. Power station ash removal - used High-pressure remote transportation of ash and slurry pipelines. Has high performance advantages.
