Description

Technical Field

[0001] The utility model relates to a canned hexagonal safety valve, belonging to the field of safety valves. Background Art

[0002] A safety valve is a valve that automatically activates based on operating pressure. It is typically installed in closed system equipment or pipelines to protect the system. When the pressure within the equipment or pipeline exceeds a specified value, the safety valve automatically opens to release the pressure, protecting the equipment and pipeline media within the specified value and preventing safety accidents.

[0003] Currently, in the market, defects in safety valves, such as structural problems, often lead to vibration between the pipeline of the safety valve and the pressure relief tank body while releasing pressure during the use of the valve. After long-term use, the sealing performance of the connection between the two will be greatly reduced, which will pose a safety hazard and seriously restrict the development of production enterprises.
