Valve block U

The verticality tolerance between 6 faces of valve block is 0.05mm; The tolerance of parallelism of relative surface is o.03mm; The flatness tolerance of each surface is 0.02mm; The perpendicularity tolerance between the thread and its mating surface is 0.05mm; The allowable deviation between all holes and the verticality of the end face is 0.05mm. In order to ensure the cleanliness of hydraulic system, the hydraulic valve block must be deburring. At present, many manufacturers still use brush for manual deburring, but also use methane blasting method for deburring. After deburring the hydraulic valve block, it needs to pass the inspection of industrial endoscope to ensure that the deburring is completed.

Then how to find the burr inside the hydraulic valve block, it must be detected by industrial endoscope. Through various processes and means, such as manual use of brush to deburring, but also methane blasting method, etc., after deburring, it is necessary to inspect it by industrial endoscope to ensure the burr is cleaned. At the same time, after the valve block is used for a long time, it is also necessary to use industrial endoscope to detect the rust spots, oil hole iron chips, chip in the hole, impurities and so on, so as to clean it as soon as possible to ensure the normal operation of the hydraulic valve block. Industrial endoscope can detect various particulate pollutants, corrosion, grease and so on attached to the inner surface of valve block. It can be said that the detection of hydraulic valve block, industrial endoscope is an indispensable tool for detection.
