Transition device of hydraulic valve stand

Abstract

The invention discloses a transition device of a hydraulic valve stand. The transition device comprises a parent plate mounted on the hydraulic valve stand and a cover plate, the parent plate is provided with a first through hole communicated with an oil hole in the hydraulic valve stand, the cover plate detachably connected with the parent plate in an attached manner is provided with a second through hole capable of being communicated with an oil hole of a hydraulic valve, the surface, attached to the cover plate, of the parent plate is provided with an upper groove communicated with the first through hole, and the second through hole is communicated with the upper groove. The parent plate is mounted on the hydraulic valve stand, the first through hole of the parent plate is enabled to be communicated with the oil hole in the hydraulic valve stand, the cover plate is mounted on the parent plate, and the first through hole is communicated with the second through hole which is communicated with the oil hole of the hydraulic valve. The upper groove is formed in one end of the first through hole, so that relative range of the first through hole and the second through hole can be increased, the parent plate can fit the cover plate provided with the second through hole at different positions, and types of the hydraulic valves that the parent plate can adapt to are expanded. During use, only the cover plate rather than the parent plate needs to be replaced, and accordingly cost of the transition device is reduced.

Description

technical field [0001] The invention relates to the field of hydraulic valve detection, in particular to a transition device for a hydraulic valve table. Background technique [0002] There are many hydraulic valves such as private valves and proportional valves used in enterprise production lines. If the valve fails to operate or has other faults during use, it needs to be tested offline to determine whether it is worth repairing. [0003] At present, the test bench in the laboratory is a fixed and single-set valve bench. Because there are many types of hydraulic valves, the diameters of the bottom surface of the valve are different. During the test bench test, it is necessary to provide a valve that matches the test bench for each type of valve. Transition valve block for connection to test benches. like figure 1 and figure 2 As shown, specifically, the upper surface of the transition valve block 02 matches the oil hole on the bottom surface of the hydraulic valve 03,...

AI Technical Summary

Problems solved by technology

[0004] Affected by factors such as high-pressure oil, the transition valve block 02 is made of better materials, and the market price is relatively high, and it is also inconvenient to store, install, and use, which greatly wastes production costs
