The invention relates to the technical field of valves, in particular to a safety valve used for a coal mine hydraulic system. The safety valve comprises a pressure bearing medium cavity and an adjusting part, wherein the pressure bearing medium cavity is used for containing pressure bearing media, and the adjusting part can be movably embedded in the pressure bearing medium cavity so as to change the volume of the pressure bearing medium cavity through moving. Under the situation that the retaining number of the pressure bearing media is reduced due to factors such as gradual leakage, the adjusting part is adjusted and moved, the volume of the pressure bearing medium cavity is changed, the changing amount of the volume is matched with the changing amount of the size of the pressure bearing media, and therefore high accuracy of the starting pressure value of the safety valve is kept. Reset adjustment on the accuracy of the safety valve can be completed under the condition that demounting of the safety valve is avoided. According to the safety valve, the repairing and maintaining convenience is remarkably improved, and durability is improved.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a safety valve used in coal mine hydraulic systems. Background technique [0002] With the development of my country's industrial and mining enterprises, various supporting equipment are being widely used. Among them, for pressure bearing equipment and systems, safety valves need to be used for system pressure protection. [0003] In recent years, the requirements for the convenience of repair and maintenance and durability of safety valves have become higher and higher. Therefore, improving the convenience of repair and maintenance of safety valves and improving their durability have become design goals. [0004] In the prior art, one structure of the safety valve is to seal the fluid medium that plays a pressure-bearing role, so that within the preset pressure-bearing range, the fluid medium in the enclosed space in the safety valve is within a certain volume range , In the hyd...
