Description

Technical Field

[0001] This utility model relates to the field of safety valve technology, and in particular to a safety valve protection device for a hydraulic support column. Background Technology

[0002] The column safety valve is one of the most important hydraulic components used in the hydraulic support system. When the hydraulic support column is subjected to increased force and the pressure reaches the set pressure value of the safety valve, the safety valve will open, and the pressurized fluid in the system will be quickly discharged through the safety valve drain hole to release the pressure and achieve the purpose of unloading.

[0003] Among them, the utility model patent with announcement number CN219691557U discloses a safety valve protection device for hydraulic support columns. However, the above patent still has certain shortcomings in use. Although it achieves external protection for the safety valve, it cannot lock and position the protective plate. The protective plate is easy to open and close, exposing the safety valve, which makes the safety valve vulnerable to damage and reduces the protective effect of the safety valve. Therefore, we propose a safety valve protection device for hydraulic support columns to solve the above problems. Utility Model Content
