Description

Safety valve for oxygen pressure relief Technical Field The utility model relates to the technical field of safety valves, in particular to a safety valve for oxygen pressure relief. Background The safety valve is a special valve which is in a normally closed state under the action of external force, when the pressure of medium in equipment or a pipeline rises to exceed a specified value, the medium in the pipeline or the equipment is prevented from exceeding the specified value by discharging the medium to the outside of the system, the safety valve belongs to automatic valves, is mainly used on boilers, pressure vessels and pipelines, controls the pressure not to exceed the specified value, and plays an important role in protecting personal safety and equipment operation. The main relief valve must undergo a pressure test to be usable. The patent document with the publication number of CN217784314U discloses a safety valve for oxygen pressure relief, which relates to the technical field of gas safety valves, and is characterized in that the safety valve body is improved to be connected with a detachable valve cover only through threads, after long-time use, the problem of loosening easily occurs, the safety valve comprises a body, an air inlet pipe and an air outlet pipe, wherein the air inlet pipe and the air outlet pipe are arranged on the body, one side of the body, far away from the air inlet pipe, is provided with the valve cover, the bottom of the valve cover is fixedly provided with a plug rod, the outer surface of the body is provided with a through groove, the inside of the body is fixedly provided with a first spring, one end of the first spring is fixedly provided with a moving block, a limiting rod is fixedly penetrated in the moving block, and a limiting groove matched with the limiting rod is formed in the plug rod.
