Description

Explosion-proof device of heat pump water tank and heat pump water tank Technical Field The utility model relates to the technical field of heat pump water tank protection, in particular to a heat pump water tank explosion-proof device and a heat pump water tank. Background In the running process of the heat pump water tank, the water vapor pressure is obviously increased along with the gradual heating of the water temperature from a low temperature state to a high temperature. This pressure change creates a significant internal pressure inside the tank, and especially for larger diameter tanks, the structure is more susceptible to expansion deformation and even the potential for bursting due to excessive expansion. In the explosion-proof design of a traditional heat pump water tank, a safety valve is generally adopted as a pressure control device, and when the system pressure exceeds a preset threshold value, the safety valve is automatically opened to release the pressure, so that the explosion accident is effectively prevented. However, for a water tank with a larger diameter, due to the huge volume and uneven stress distribution, when the system pressure does not reach the opening threshold of the safety valve, the water tank structure may still be deformed locally, and a certain potential safety hazard exists.
