A kind of hot water supply system
Technical field
The present invention relates to the hot water supply in the daily life, especially relate to a kind of hot water supply system.
Background technology
In daily productive life, use the local a lot of of hot water, gas heater or solar water heater what mostly use aspect the use hot water at present, these two kinds of water heaters are fit to use take one family as unit, the supply of inconvenient collective, gas heater when in use, combustion gas may be leaked, easily human body is produced harm even life threatening, and waste when in use a large amount of heat resources, solar water heater mainly is to utilize solar energy that water is heated, yet in overcast and rainy, solar water heater is just inapplicable, these two kinds of water heaters at first all will be released the cold water in the pipe when in use, re-use, take care of the pence like this water resource that waste is a large amount of.
Summary of the invention
Technical problem to be solved by this invention provides a kind of can the use at any time and the hot water supply system of saving water resource.
The present invention solves the technical scheme that its technical problem takes: a kind of hot water supply system, comprise water storage filling and heating water tank, described heating water tank is provided with delivery port, water inlet and water return outlet, delivery port is filled with water storage by the hot water line and is connected, water inlet is by cold water pipeline access cold water, water return outlet is filled with the bottom by water return pipeline and water storage and is connected, water storage is filled with delivery port and is connected water use sector, hot water backwater's pipeline of water use sector is connected with the top that water storage is filled with, and cold water is filled with to water storage respectively and water use sector supply cold water by the cold water pipeline.
Further concrete, the hot water line between described delivery port and water storage are filled with is provided with hot water temperature-sensing valve and temperature sensor.
Further concrete, the water return pipeline between described water return outlet and water storage are filled with is provided with return water temperature control valve, is provided with temperature sensor and is connected with return water temperature control valve in water storage is filled with.
Further concrete, the hot water backwater's pipeline between described water use sector and water storage are filled with is provided with hot water backwater's temperature-sensing valve and temperature sensor.
Further concrete, at least two of described heating water tank.
The invention has the beneficial effects as follows: adopted after the said system, can use at any time hot water, hot water circuit is just come and the temperature constant of hot water, can supply by the ratio of regulating hot water and cold water according to the temperature required difference of user, can save water resource.
Description of drawings
Fig. 1 is hot water supply system schematic diagram of the present invention.
Among the figure: 1, heating water tank; 2, water storage is filled with; 3, water use sector; 4, hot water line; 5, water return pipeline; 6, cold water pipeline; 7, hot water temperature-sensing valve; 8, return water temperature control valve; 9, hot water backwater's temperature-sensing valve; 10, hot water backwater's pipeline.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
A kind of hot water supply system as shown in Figure 1, comprise 2 and two heating water tank 1 of water storage filling, described heating water tank 1 is provided with delivery port, water inlet and water return outlet, delivery port is filled with 2 by hot water line 4 with water storage and is connected, water inlet is by cold water pipeline 6 access cold water, water return outlet is filled with 2 bottoms by water return pipeline 5 and water storage and is connected, water storage is filled with 2 delivery ports and is connected water use sector 3, the hot water line 4 of water use sector 3 is connected with the top of water storage filling 2, and cold water is supplied cold water to water storage filling 2 and water use sector 3 respectively by cold water pipeline 6; Hot water backwater's pipeline 10 that described delivery port and water storage are filled with between 2 is provided with hot water temperature-sensing valve 7 and temperature sensor; The water return pipeline 5 that described water return outlet and water storage are filled with between 2 is provided with return water temperature control valve 8, is provided with temperature sensor and is connected with return water temperature control valve 8 in water storage filling 2; Hot water backwater's pipeline 10 that described water use sector 3 and water storage are filled with between 2 is provided with hot water backwater's temperature-sensing valve 9 and temperature sensor.
The process that the hot water of whole system and cold water flow is: 1, cold water branch road, cold water divide three the tunnel to be supplied to respectively heating water tank 1, water storage filling 2 and water use sector 3; 2, hot water branch road, at first, cold water heats in heating water tank 1, hot water after heating reaches design temperature, hot water temperature-sensing valve 7 is opened and is flowed to water storage by hot water line 4 and fill with 2 and carry out stored hot water, when water use sector 3 needed to use hot water, water storage filled with 2 to water use sector 3 hot-water supplies; 3, the backflow branch road, the backflow branch road is divided into two parts, first fills with between 2 in heating water tank 1 and water storage, when the temperature in the water storage filling 2 does not reach Application standard, return water temperature control valve 8 is opened and water storage is filled with water in 2 is back in the heating water tank 1 and again heats, second portion is filled with between 2 at water use sector 3 and water storage, when the hot water temperature in the hot water line at water use sector 3 places reduces or does not reach Application standard, hot water backwater's temperature-sensing valve 9 is opened, the hot water return that temperature is inadequate is filled with in 2 to water storage, and water storage is filled with 2 hot water that will reach temperature and added in the hot water line.
It is emphasized that above is better implementation column of the present invention, and every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
