Between.
In feasible embodiment, the second water temperature sensor is set between the heat exchanger and the water outlet.
In feasible embodiment, the water inlet end connects cold water water inlet, and the water outlet connects hot water outlet.
In feasible embodiment, the user terminal includes that at least one uses water spot and level pressure back-water valve (BWV).
In feasible embodiment, when it is described with water spot be it is two or more when, the level pressure back-water valve (BWV) be connected to away from
It is farthest from the water inlet end and the water outlet described to use water spot.
In feasible embodiment, the gas heater circulation line is domestic gas-fired water heater circulation line, institute
Stating with water spot is kitchen platform basin, bathroom platform basin or bathroom shower.
In order to be further understood that the feature and technology contents of the application, please refer to below in connection with the detailed of the application
Illustrate and attached drawing, however, the drawings only provide reference and explanation, is not used to limit the application.
Detailed description of the invention
The aforementioned and other aspects of the application will more completely be managed and that is done with reference to the accompanying drawings is discussed in detail
Solution and understanding, in the accompanying drawings:
Fig. 1 is the schematic diagram of one embodiment of the prior art；
Fig. 2 is the schematic diagram of second embodiment of the prior art；
Fig. 3 is the schematic diagram of one embodiment of the application.
Specific embodiment
For help those skilled in the art definitely understand this application claims theme, with reference to the accompanying drawing in detail
The specific embodiment of the application is described.
As shown in figure 3, a kind of domestic gas-fired water heater circulation line 10, including water inlet end 1, water outlet 2 and heat exchanger
8, the gas heater circulation line 10 further includes a back water pump branch 20,21 He of branch entrance of the back water pump branch 20
Branch way outlet 22 is arranged between the water inlet end 1 and heat exchanger 8, and the gas heater circulation line 10 only passes through
The water inlet end 1 and the water outlet 2 are connected to user terminal, and back water pump 4, the branch are provided on the back water pump branch 20
Check valve 5 is provided between entrance 21 and the branch way outlet 22.
Wherein, the water inlet end 1 connects cold water water inlet, and the water outlet 2 connects hot water outlet.The water inlet end 1
Water valve 7 and flow sensor 3 are set between the heat exchanger 8.It is arranged between the water inlet end 1 and the heat exchanger 8
First water temperature sensor 6.The water valve 7 and the setting of flow sensor 3 the back water pump branch 20 and the heat exchanger 8 it
Between.First water temperature sensor 6 is arranged between the back water pump branch 20 and the water inlet end 1, the heat exchanger 8 with
Second water temperature sensor 9 is set between the water outlet 2.
In this embodiment, user terminal includes two with water spot 30, and level pressure back-water valve (BWV) 40 is connected to described in distance
The use water spot 30 of water inlet end 1 and the water outlet 2 farthest.It is described with water spot 30 be, for example, kitchen platform basin, bathroom platform basin or
Bathroom shower.
Typically, when having hot water demand with water spot 30, cold water is entered by water inlet end 1, is passed by the first temperature
Sensor 6, check valve 5, flow sensor 3 and water valve 7, further along water route through second temperature sensor after the heating of heat exchanger 8
9, it is flowed out via water outlet 2 to water spot 30.In order to ensure water temperature initial when being used with water spot 30 is also able to maintain in a certain ideal
Temperature, when temporarily not having water demand with water spot 30, under the action of 4 draft of back water pump, a part of cold water is still by water inlet end
1 enters, and by the first temperature sensor 6, back water pump 4, flow sensor 3 and water valve 7, is flowed out further along water route by water outlet 2
To level pressure back-water valve (BWV) 40, to remain a certain amount of hot water in pipeline.Check valve 5 can prevent water flow from being returned by back water pump 4
Flow to water inlet end 1.As a result, no matter when having hot water demand with water spot 30, initial water temperature also be can control more satisfactory
Temperature.The basic function of each building block is well known to those skilled in the art in water heater principle and pipeline, herein no longer
It repeats.Present embodiment only passes through the water inlet end 1 as a result, and the water outlet 2 is connected to user terminal, and structure is simple, is not required to
Want port reservation position additional in user family.
Although having been shown and described the application based on specific embodiment, the application is not restricted to shown thin
Section.On the contrary, the various details of the application can be modified in the range of claim and its equivalent replacement.
