A Fixing Plate Structure Facilitating Surface Reprocessing

Abstract

The invention discloses a fixed disc structure convenient for surface reprocessing. According to the fixed disc structure, a fixed disc comprises a fixed disc body and a plurality of material pipes arranged at the bottom of the fixed disc body; the fixed disc further comprises a plurality of process pipes and a cylindrical seat plate, wherein the process pipes are arranged on the side wall of the fixed disc body; the cylindrical seat plate is arranged at the bottom of the fixed disc body; an inner cavity is defined by the cylindrical seat plate; and the material pipes are arranged in the inner cavity formed by the cylindrical seat plate. According to the fixed disc structure convenient for the surface reprocessing, the process pipes are arranged on the side wall of the fixed disc body so that pipes welded at the bottom of the fixed disc are reduced and only the material pipes are arranged; and after the process pipes and the material pipes are welded on the fixed disc body, the surface of the fixed disc body can be conveniently reprocessed and the flatness of the surface of the fixed disc body is guaranteed.

Description

technical field [0001] The invention relates to a fixed disk used for a rotary valve, in particular to a fixed disk structure which facilitates surface reprocessing. Background technique [0002] At present, with the improvement of user requirements, the specifications of rotary valves are from 800, 1000, 1200, 1400 to 1600, and the size specifications are getting larger and larger, and the surface volume of the fixed plate is also increased, and the flatness of the fixed plate is required. It is below 0.025mm. Usually, after the pipes on the fixed plate are welded, the fixed plate will produce welding deformation, so that the surface of the fixed plate cannot meet the flatness requirement. In the actual process, it is hoped that the flatter the surface of the fixed plate, the better. The flatter the surface of the fixed plate, the less the leakage inside the rotary valve. [0003] Such as figure 1 As shown, the fixed plate of the prior art includes a fixed plate body 5',...

AI Technical Summary

Problems solved by technology

The disadvantage is that all the tubes are welded at the lower part of the fixed plate, so that the surface of the bottom of the fixed plate will shrink, and the middle of the upper surface of the fixed plate will be raised, but it cannot be reprocessed, so that the flatness of the fixed plate cannot reach 0.025mm The following requirements
