Problems solved by technology
[0003] 1. The existing safety valve technology has no pressure display and warning function, and the staff at the post cannot observe and judge the size and change of the working resistance of the hydraulic support
Not to mention long-distance observation and judgment and analysis of changes in the top and bottom plates
[0004] 2. Because there is no memory of the initial pressure, such as system pressure changes during work, whether the safety valve operates, whether the system leaks, etc., there is no benchmark mark for comparison, and it is impossible to judge, analyze, solve problems and eliminate hidden dangers

The invention discloses a displayed pressure memorizing warning type safety valve, and relates to a spring type safety valve for a coal mine fully-mechanized coal mining hydraulic support and aims at overcoming defects in the existing safety valve technology. By means of the provided displayed pressure memorizing warning type safety valve, the system pressure can be displayed at any time, and the changing situation of the support work pressure can be recorded at any time; and meanwhile, in the proper range, the work state of the safety valve can be observed in the long distance according to different colors of light emitting patterns arranged on the outer surface of a valve body so that the safety support condition of the support can be judged in the long distance.
Description
technical field [0001] The invention relates to a spring type safety valve for fully mechanized mining hydraulic supports in coal mines. Background technique [0002] At present, although there are many types of spring-type safety valves used on hydraulic supports for fully mechanized mining at home and abroad, their basic principles and structures are roughly the same. They all open and close the discharge port of the safety valve according to the level of system pressure, and have a single function. According to long-term observation, there are still many deficiencies in the various types of safety valves currently in use. Such as: [0003] 1. The existing safety valve technology has no pressure display and warning functions, and the staff at the post cannot observe and judge the size and change of the working resistance of the hydraulic support. Not to mention the long-distance observation and judgment analysis of the changes in the top plate and the bottom plate. [0...
