I. Detailed Description:

The safety valve for refrigeration units is used in refrigeration equipment as an overpressure protection device. When the operating pressure of the equipment exceeds the allowable value, the valve automatically opens, and according to the equipment's operating requirements, it discharges a specified amount of medium to prevent the pressure from continuing to rise, thereby protecting the entire system.
