Description

The system of cold water in a kind of the automatic recovery hot water pipeline
Technical field
The invention belongs to water heater arrangement technical field, be specifically related to the system of cold water in a kind of the automatic recovery hot water pipeline.
Background technology
China is a very unbalanced country of distribution of water resources, and some regional water are deficient for a long time, and the life of people is had a strong impact on.Along with people progressively deepen the understanding of water deficiency, using water wisely is more and more accepted by the public.At many families and bathhouse, because thermal water source's distance bathing tap is comparatively far away, makes often have some clean cold water first to drain in hot water pipeline, cause water resource waste, this situation is using the heating system of solar water heater especially serious.For this problem, people generally first can be discharged to cold water in bucket or basin, but do like this and need manual operation very inconvenient, and are not suitable for the large place of water consumption.And existing cold water recovery system device structure is complicated, manufacturing cost is high, is unfavorable for that the marketization is promoted, and switch solenoid control, also with water pump to pipe pressurizing, additionally need consume electric energy, add job costs.
Summary of the invention
The object of this invention is to provide the system of cold water in a kind of the automatic recovery hot water pipeline, this system makes the cold water in hot water pipeline not need consumption electric energy also again to utilize to cold water pipes by the automatic recovery, solves the problem that existing cold water recovery system needs extra consumption electric energy.
The technical solution adopted in the present invention is, the system of cold water in a kind of the automatic recovery hot water pipeline, comprises hot water line, reclaim line and cold water pipeline, hot water line is connected with water heater in turn, valve, temperature control divert valve and check-valves, the water inlet end of temperature control divert valve is also provided with hot water outlet pipe; Reclaim line is arranged on the hot water line between temperature control divert valve and check-valves, and the end of reclaim line is provided with storage tank; Cold water pipeline is connected with three way type venturi water-blaster, and the water side of three way type venturi water-blaster is provided with cold water outlet pipe, and the side pipe of three way type venturi water-blaster is connected with the water side of check-valves.
Feature of the present invention is also,
Storage tank is sealed construction.
The top of storage tank is provided with pressure safety valve.
The invention has the beneficial effects as follows, the system of cold water in a kind of the automatic recovery hot water pipeline, by the memorial alloy temperature control divert valve of native system, do not need to consume additional electrical energy and just automatically can open or close hot water line according to water temperature, saved the energy; By the sealing radiator of native system, the pressure energy in water supply pipe can be stored while water storage; Clean cold water storage in hot water line also utilizes by native system automatically again, reaches the effect of saving water resource.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As depicted in figs. 1 and 2, the system of cold water in a kind of the automatic recovery hot water pipeline, comprise hot water line 10, reclaim line 20 and cold water pipeline 30, hot water line 10 is connected with water heater 40 in turn, valve 14, temperature control divert valve 11 and check-valves 12; The water inlet end of temperature control divert valve 11 is also provided with hot water outlet pipe 13; Reclaim line 20 is arranged on the hot water line 10 between temperature control divert valve 11 and check-valves 12, and the end of reclaim line 20 is provided with storage tank 21, and storage tank 21 is sealed construction; Cold water pipeline 30 is connected with three way type venturi water-blaster 31, and the water side of three way type venturi water-blaster 31 is provided with cold water outlet pipe 32, and the side pipe 310 of three way type venturi water-blaster 31 is connected with the water side of check-valves 12; As shown in Figure 3, the top of storage tank 21 is provided with pressure safety valve 22.
In a kind of the automatic recovery hot water pipeline of the present invention, the operation principle of the system of cold water is, when fetching water from hot water outlet pipe 13, valve 14 controls the opening and closing of whole hot water line 10, after valve 14 is opened, current first flow into temperature control divert valve 11 by hot water line 10, but owing to having cold water in hot water line 10, because temperature control divert valve 11 has the feature according to the opening and closing of water temperature control piper, temperature control divert valve 11 can open hot water line 10, and cold water just injects storage tank 21 by reclaim line 20 and stores; Due to the existence of cold water pipeline 30 hydraulic pressure, the cold water in hot water line 10 can't flow into wherein; When cold water is drained, hot water contacts's temperature control divert valve 11, cut off hot water line 10 after temperature control divert valve 11 is heated, hot water just flows to hot water outlet pipe 13.
When fetching water from cold water outlet pipe 32, the cold water in cold water pipeline 30 flows to cold water outlet pipe 32 by three way type venturi water-blaster 31, and the cold water simultaneously in storage tank 21 flows out from reclaim line 20, also flows to cold water outlet pipe 32 by side pipe 310.
In the present invention, hot water line 10 is provided with check-valves 12, the cold water in cold water pipeline 30 can not flow to hot water line 10; Three way type venturi water-blaster 31, according to venturi principle, makes the water in storage tank 21 suck from side pipe 310, and without the need to additionally arranging water pump, the cold water that simultaneously improve native system goes out water speed, thus raises the efficiency; Storage tank 21 is sealed construction, and while making it not need high-order installation, effectively can also store the pressure in water supply line, the cold water further increasing native system goes out water speed.Further, the top of storage tank 21 is provided with pressure safety valve 22, and protection storage tank 21 is at certain safe pressure operated within range.
