Detection device for marking whether hydraulic valve mounting hole is cleaned or not

Abstract

The invention relates to the related field of hydraulic valves, and discloses a detection device for marking whether a hydraulic valve mounting hole is cleaned or not. The device comprises a main body box, a valve block detection cavity is formed in the main body box, an annular square groove is formed in the lower side of the valve block detection cavity in a communicating manner, a driving shaft gear cavity is formed in the lower side of the annular square groove, a wind wheel cavity is formed in the lower side of the driving shaft gear cavity, a sliding push plate is pushed by wind entering the valve body mounting hole to make contact with a pressure switch, and therefore a marking rod is triggered to move downwards to mark the valve body mounting hole which is being detected, and the cleaned valve body mounting hole is marked, so that the cleaning condition can be known by workers more visually, valve body mounting holes which are not cleaned thoroughly are cleaned again, meanwhile, a supporting shaft is driven by a driven shaft to move, automatic continuous detection is achieved, and therefore the detection efficiency is improved.

Description

technical field [0001] The invention relates to the related field of hydraulic valves, in particular to a detection device for marking whether a hydraulic valve installation hole is clean. Background technique [0002] At present, the hydraulic valve will accumulate a layer of dirt after being used for a period of time and needs to be cleaned, but most of them are assembled directly after cleaning. When the four assembly holes on the valve block are not cleaned, it is easy to cause the inside to be in In the long run, there is a possibility of oil leakage in the hydraulic valve gap during assembly. On the other hand, some personnel will test the cleaned valve block based on experience, but this detection method has low detection efficiency and poor detection effect. Contents of the invention [0003] The object of the present invention is to provide a detection device for marking whether the installation hole of the hydraulic valve is cleaned, which can overcome the above-...
