Split structure for recycling cold water

Abstract

The invention discloses a flow dividing structure used for recovering cold water. The flow dividing structure comprises an outer sleeve; a flow dividing cavity, a backflow cavity and a hot water cavity are arranged in the outer sleeve; the backflow cavity is communicated with the flow dividing cavity through a first port; the hot water cavity is communicated with the flow dividing cavity through a second port; a piston barrel is arranged in the flow dividing cavity; a certain gap exists between the outer wall of the piston barrel and the inner wall of the outer sleeve; a first through hole, a second through hole and a third through hole are formed in the barrel wall of the piston barrel; a temperature sensing actuator and a first elastic part are arranged in the piston barrel; the temperature sensing actuator is provided with a disk seal; the inner wall of the outer sleeve is provided with an elastic element; at least 1ML of water can be contained in the cavity located at the left side of the piston barrel in the outer sleeve. According to the flow dividing structure disclosed by the invention, accurate cold water and hot water flow dividing can be realized through sliding fit between the piston barrel and the outer sleeve, and meanwhile, the outlet water temperature of hot water can also be regulated as needed; the flow dividing structure has the advantages that judgment is accurate, the backflow efficiency is high, the operation is stable, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of heating valves, in particular to a diversion structure for recycling cold water. Background technique [0002] In modern life, since the water supply pipe of the hot water supply system usually has a certain length, when hot water is used, a certain amount of retained cold water must be discharged every time to supply hot water, especially when the water point is far from the hot water supply point. This problem is particularly prominent at a distance. If things go on like this, it has both caused a large amount of waste of water resources and increased the additional expenses of users. [0003] At present, there are some technologies that can solve the above problems. For example, the temperature-adjusting cold and hot water diverter valve disclosed in Chinese Patent No. 201420249760.1 can solve the problem of cold water backflow, but it has the following problems: When water leaks or is caused by huma...

If things go on like this, it has not only caused a lot of waste of water resources, but also increased the additional expenses of users

[0003] At present, there are some technologies that can solve the above problems. For example, the temperature-adjusting cold and hot water diverter valve disclosed in Chinese Patent No. 201420249760.1 can solve the problem of cold water backflow, but it has the following problems: When there is water leakage or artificial leakage, the piston is prone to misjudgment and starts to work, which will waste hot water resources; and when the cold water circuit or the water inlet pipe is equipped with a water pump or a booster pump, it is easy to turn on the hot water faucet. There is a situation where the diverter valve cannot be activated, which will seriously affect the supply of hot water
