[0002] In the current market water equipment, hot water supply system usually adopts single solenoid valve to control the water inlet process of hot water tank. Although this design meets the basic hot water supply demand to some extent, it is easy to cause hot water in hot water tank to flow back to solenoid valve, and this backflow not only affects the normal work of solenoid valve, but also causes the internal parts of solenoid valve to be damaged by thermal stress due to long-time operation in high-temperature environment, leading to gradual decline in sealing performance, and eventually may cause poor sealing. Poor sealing not only reduces the working efficiency of water equipment, but also may cause safety hazards such as water leakage and short circuit.
