Description

Technical Field

[0001] The utility model relates to the technical field of safety valve testing, in particular to a TP valve testing bench. Background Art

[0002] The TP valve, also known as a temperature and pressure safety valve, primarily functions to limit the temperature and pressure of a water tank. It's primarily used in pressurized water tanks. When the water in the tank is heated, if the pressure reaches the set pressure of the temperature and pressure safety valve, the valve releases pressure to protect the tank. When the water in the tank reaches the set temperature of the temperature and pressure safety valve, the valve releases water and simultaneously replenishes cold water to lower the water temperature, providing safety protection.
