Application grinding method of abrasive wheel muller in valve

Abstract

The invention relates to a grinding method with the application of the grinding wheel muller in the valve; wherein, the grinding wheel muller comprises a pneumatic motor, a drive rod, a grinding wheel plate, and a plurality of grinding wheel heads. The compressed air drives the pneumatic motor connected with the drive rod through the joint shaft; a driving bevel gear and a driven bevel gear arranged on the lower end of the drive rod are meshed with each other; the universal joint is connected with the grinding wheel on the external part of the body; the grinding wheel heads are arranged at both ends of the grinding wheel. The grinding method applied in the valve can be normally used in the condition of steam, water and wet, and cold grinding is not needed in the high temperature of 400 to 500 DEG C; online grinding can be used when the large valve leaks; grinding wheel heads and transmission regulate rods matched with the sealing surface can be assembled on valves with different specification, and repairing can be used when valve sealing surface leaks. The invention has the advantages of fast grinding, lower material cost, high grinding precision, simple operation, safety and reliability, low failure rate, long time continuous operation under any bad environment, and application for grinding on various valves.

Description

Technical field [0001] The invention relates to a method for applying a grinding wheel grinder to a valve, and belongs to a high-speed grinding technology for high hardness, high temperature, steam and water environment on the sealing surface of the valve. Background technique [0002] At present, the valve is an indispensable and important supporting equipment in the electric power, petrochemical, and metallurgical industries. The pollution caused by the leakage of the valve sealing surface and the loss caused by the leakage accident are more serious. The use of electric grinders is particularly important in the flammable and explosive industries, which can easily cause explosions and fires; the use of self-adhesive emery cloth for grinding is easy to soften and fall off in the harsh environment of high temperature, steam and water, and diamond The cost of the grinding head is too high; if the material of the large valve is hard and the defects are serious, the slow grinding spe...

Problems solved by technology

The use of electric grinders is especially important in flammable and explosive industries, which can easily cause explosions and fires; the use of self-adhesive abrasive cloth for grinding encounters high temperature, steam, and water in harsh environments. The rubber surface of self-adhesive abrasive cloth is easy to soften and fall off. The cost of the grinding head is too high; if the material of the large valve is hard and the defect is serious, the grinding speed is slow and the repair period is long, which directly affects the economic benefit
