Description
Technical Field
[0001] The utility model relates to the technical field of thermostatic valves, in particular to a wireless Bluetooth thermostatic one-way H-type valve. Background Art
[0002] Thermostatic valves usually contain a temperature sensing element, such as a thermistor or a memory alloy spiral temperature sensing probe. These temperature sensing elements can sense temperature changes and adjust the position of the valve core accordingly, thereby controlling the opening of the hot and cold water inlets and outlets. When the user sets a temperature, the thermostatic valve will automatically maintain the set temperature. If the actual temperature is lower than the set value, the temperature sensing element will shrink due to the decrease in temperature, driving the valve core to move upward, reducing the opening of the cold water outlet, increasing the opening of the hot water outlet, and increasing the temperature of the mixed water; conversely, if the actual temperature is higher than the set value, the temperature sensing element will expand due to the increase in temperature, driving the valve core to move downward, increasing the opening of the cold water outlet, reducing the opening of the hot water outlet, and lowering the temperature of the mixed water.
[0003] The thermostatic valve is a one-way valve installed at the inlet of hot and cold water to prevent hot and cold water from flowing into each other and cold water from flowing back into other equipment. The temperature sensing element of the thermostatic valve is usually built into the thermostatic valve head, which can respond to changes in external temperature and control the temperature of the radiator by controlling the flow in the system. The performance of the thermostatic valve depends on factors such as the reaction speed and execution force of the temperature sensing element, the sealing performance of the valve core, and the rapid reset ability of the spring.
[0004] Zero cold water water heater is a new type of water heater. Compared with traditional water heaters, it has a built-in return pump or booster pump, and has a jog circulation function. The pressure generated by the return pump is greater than that of tap water. When the hot water reaches a certain set value, the water pump turns on and sends the cold water in the water pipe back to the water heater for heating.
