Description

Technical Field

[0001] The invention relates to the technical field of polishing equipment, in particular to a polishing equipment for end face processing in valve production. Background Art

[0002] As a control component in the fluid conveying system, the valve has functions such as shutoff, regulation, and diversion. The end face processing is crucial and is related to the sealing and conveying performance and service life of the valve. Most valves are in the shape of three-way pipes and are fixed in the pipeline through flanges on the opposite end faces. Traditional polishing equipment usually fixes the valve at one end, polishes the end face with the polishing block on the polishing disk, and then flips the valve to polish the other end after one end is completed, resulting in low polishing efficiency and high labor intensity for workers. Some valves use polishing equipment at both ends of the valve for simultaneous polishing, but this requires two sets of polishing equipment and transmission equipment, which greatly increases the cost of use.

[0003] When double-sided grinding of valves is performed, the valves are usually kept in a stationary state, and the grinding of the valves requires centering operations. In addition, the valves need to be fixed separately during grinding to prevent the valves from moving with the polishing device, resulting in low processing efficiency. Summary of the invention

[0044] The first motor 501 is started, and the driving shaft of the first motor 501 drives the first gear 502 to rotate. The rotation of the first gear 502 drives the fourth gear 803 to rotate. The rotation of the fourth gear 803 drives the water pump 802 to rotate. The rotation of the water pump 802 drives the polishing liquid from the polishing liquid pool 801 into the interior of the polishing liquid delivery pipe 804, and enters the first rotating joint 806 along the hard pipe 805, passes through the first rotating joint 806 to the interior of the water inlet pipe 8084, passes through the second rotating joint 8081 to The polishing liquid reaches the inner wall of the liquid outlet pipe 8082 and is sprayed along the spray pipe 8083 to spray the polishing liquid on the surface of the side of the valve, thereby performing polishing and grinding. The spray pipe 8083 is set at an angle so that the reaction force of the polishing liquid during spraying drives the liquid outlet pipe 8082 to rotate along the side of the second rotating joint 8081, thereby spraying the polishing liquid evenly on the side of the valve. The polishing liquid is automatically sprayed through spontaneous rotation, thereby performing even spraying of the polishing liquid, thereby avoiding the existence of polishing dead corners and ensuring the quality of polishing.
