[0002] Solar water heating system is a technology that uses solar energy to heat water. It is widely used in many fields such as home, business and industry. It collects the sun's heat energy through solar collectors to heat water. The collector is usually composed of glass plates, insulation materials and pipes. Sunlight passes through the glass plates and shines on the heat-absorbing materials inside the collector, absorbing the heat energy and transferring it to the water flowing through the pipes.

[0003] Solar water heating systems are prone to overpressure problems when in use, which usually refers to excessive water pressure in the system, which may cause damage to the water tank or pipes. It may be that the water level in the system is too high, which may be caused by a failure of the automatic water replenishment valve, or in strong sunlight, the collector is in a high temperature state for a long time, and the increased water temperature causes the water pressure to increase. Therefore, a solar water heating overpressure safety device is needed to ensure the safety of the solar water heating system when in use. Utility Model Content
