Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water supply control, and more specifically, to a constant temperature water supply control system for a water project. Background Art
[0002] Water supply in public places, factories, scientific research institutes, residential areas, etc. usually adopts a simple method of adding water to the water tank, heating it, and using a water pump to pump cold water or hot water for pressurized supply. Although some places use PLC controllers, frequency conversion devices and other advanced equipment to control water volume, water temperature, and water pressure, when there are fewer customers, the water temperature in the return pipe is high and still needs to flow into the heat storage tank and be heated again, resulting in energy waste and conservation, and high energy loss. Utility Model Content
[0003] In order to solve the above-mentioned problem of high energy loss, an energy-saving water project constant temperature water supply control system is provided.
[0004] The above technical purpose of the utility model is achieved through the following technical solutions: a water project constant temperature water supply control system, which includes a buffer water tank, a heat storage tank, a first actuator valve, a hot water supply pump, and a return pipe in sequence along the water flow direction. A first temperature probe and a water inlet valve for controlling water inlet are provided in the buffer water tank. A second actuator valve is provided between the buffer water tank and the water supply pump. The first actuator valve, the second actuator valve and the first temperature probe are all electrically connected to a controller, and the controller is used to control the opening and closing of the first actuator valve and the second actuator valve.
[0005] Preferably, the water return pipe is provided with a plurality of water outlets, and both ends of the water return pipe are respectively connected to the hot water supply pump and the hot water storage tank.
[0006] Preferably, the hot water storage tank is connected to a heating device, and the heating device is used to heat the water in the hot water storage tank.
[0007] Further preferably, a built-in second temperature probe is provided in the heat storage tank, and the second temperature probe is electrically connected to the controller.
[0008] Preferably, a third temperature probe is provided in the return pipe near the hot water supply pump, and the second temperature probe is electrically connected to the controller.
[0009] Preferably, the water inlet valve is connected to the tap water system.
[0010] The working process of the utility model is as follows: after the water flows through the buffer water tank, it slowly and quantitatively enters the heat storage tank. After being heated, the temperature reaches the set standard. Under the action of the controller, the first execution valve is opened. Under the action of the hot water supply pump, the hot water flows into the return pipe. Each user uses constant temperature hot water through multiple water outlets arranged in the return pipe. The remaining hot water enters the buffer water tank through the return pipe. The temperature measured by the first temperature probe is fed back to the control center. When the temperature of the buffer water tank is higher than the set standard, the control center opens the cold water inlet valve to let in tap water. When the temperature reaches the set standard, the control center controls the opening of the second execution valve to repeat the water supply work.
[0011] In summary, the utility model has the following beneficial effects: by setting the second actuator valve and the first temperature probe, when the temperature in the buffer water tank exceeds the standard temperature, it is only necessary to allow cold water to enter under the control of the controller, and then open the second actuator valve, so that the water in the buffer water tank does not need to be heated again and enters the return pipe for direct use, and does not need to be heated again through the heat storage tank, thereby saving energy.
