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
The present invention relates to the application grinding method of a kind of amery wheel grinding machine on valve, belong to a kind of on the valve sealing face to high rigidity, high temperature, band vapour, band water environment under the high speed grinding technique.
Background technology
At present, valve is a kind of indispensable important corollary equipment in electric power, petrochemical industry, metallurgical industry, owing to valve sealing face is revealed and to be caused that the loss that pollution, leakage accident cause is comparatively serious.Adopt motor-driven mill, particularly important in inflammable and explosive industry, easily set off an explosion and fire; Adopt the self-adhesion emery cloth to grind to run into that self-adhesion emery cloth glue face easily softens, comes off in high temperature, band vapour, the band water adverse circumstances, adopt the diamond grinding head cost too high; As run into that large-scale valve material is hard, defective is serious because grinding rate is slow, rush to repair long in time limitly, directly influence economic benefit.
Summary of the invention
In order to address the above problem; purpose of the present invention provides the application grinding method of a kind of amery wheel grinding machine on valve; adopt the ZL200520020230.0 patent, " valve air sander grinder " can normally grind the sealing surface of various valves under adverse circumstances; in inflammable and explosive industry, can not cause fire and explosion accident; grinding rate is fast, and the repairing duration is short, and the grinding-material expense is low; make power station and chemical enterprise shutdown loss little, reach energy saving purposes.
The technical solution adopted for the present invention to solve the technical problems is: the application grinding method of a kind of amery wheel grinding machine on valve.Amery wheel grinding machine comprises air motor, drive link, grinding wheel disc, emery wheel bistrique, adopts compressed air directly to drive air motor, is connected with drive link by connecting axle by air motor, drives drive link and rotates at a high speed; Be equipped with the driving bevel gear formation transmission device that is meshed with driven bevel pinion in the lower end of drive link, engine body exterior at amery wheel grinding machine is connected with the grinding wheel disc with the adjusting ball by universal joint, be provided with groove at the two ends of grinding wheel disc, the emery wheel bistrique is packed in the groove, the emery wheel bistrique is fixed with gland.
At the application grinding method on the valve: when revealing appears in valve,, no matter corrode or the weight that damages all can adopt this machine and Ginding process to grind reparation because of valve sealing face is corroded or damages.This machine is the air motor that adopts, and does not produce electric spark and leaky during operation, can not cause fire and explosion accident to inflammable and explosive enterprise, also can be because of electric leakage crisis personal safety under wet environment; What the bistrique of this machine adopted is the emery wheel bistrique, all can grind any hard rigid material, emery wheel bistrique normal grinding operation in band vapour, band water, moist adverse circumstances, particularly the emery wheel bistrique is high temperature resistant, when occurring leaking as the valve on the large-sized boiler, shut down the back and under the situation of 400～500 ℃ of high temperature, need not cool off and to grind the defective or the damage of valve sealing face, reduce downtime; Run into when leaking appears in large-scale valve sealing face and can onlinely rush to repair milled processed; Only need be equipped with the emery wheel bistrique that conforms to valve sealing face and adjust drive link and can grind at the valve sealing face of different size; Use this machine grinding wheel bistrique grinding speed fast, the grinding-material expense is low, the grinding precision height.
The invention has the beneficial effects as follows: the muller bistrique is high temperature resistant, and is corrosion-resistant, and grinding rate is fast, the safety coefficient height, and Master Cost is low, grinding precision height, but long-time continuous operation under any adverse circumstances; Can eliminate defective fast at the sealing surface that material is hard; Simple to operate, fault rate is low; The consumable material cost is low, and maintaining is convenient, and drive link can be adjusted arbitrarily, can be fit to the grinding of all size valve sealing face; The specification of emery wheel only need be equipped with to conform to valve sealing face just can guarantee constant grinding rate. be fit to various valve-seatings and use.
