Description
Technical field
The utility model relates to a kind of hot water apparatus, especially a kind of hot water circulating device is also related to using the dress
The hot-water heating system set, belongs to technical field of water heaters.
Background technique
It is well known that when opening the facility of gas heater etc, when tending not to plug and play, and needing to wait one section
Between.One being since it is desired that the cold water lodged in pipeline is bled off, and two being because gas heater needs in security consideration
First to start blower could light a fire.
For this purpose, the Chinese patent document that notification number is 205332549 U of CN 105299875 A and CN successively discloses
Being arranged can open i.e. with the technical solution of circulating-heating return pipe, although can preheat the cold water in pipeline in this way to realize
Heat, but not only install complex, but also it is dfficult to apply to be transformed the water heater before without water return pipeline.
Later, application No. is 201611194663.7 Chinese patent application a kind of water loop module is disclosed and using should
The hot-water heating system of water loop module comprising hot water facility, the cold water pipeline being connected to the water inlet of hot water facility and with heat
The hot water line of the water outlet connection of wetting system.Water loop module is arranged in the outside of hot water facility and is connected to hot water line
Between cold water pipeline, so as to selectively communicate with hot water line and cold water pipeline to establish circulation between hot water facility at it
Water route, and the cold water in the circulation waterway is heated in turn.In addition, application No. is 201720770743.6 Chinese patent application public affairs
A kind of water loop module and the hot-water heating system comprising the water loop module are opened, which is arranged in the outer of hot water facility
Portion is simultaneously connected between hot water line and cold water pipeline, to optionally establish circulation waterway between hot water facility at it.
The water loop module includes the auxiliary hot water apparatus of shell and setting inside the shell.
But can not solve the problems, such as heating equipment frequent start-stop in the application of the above-mentioned prior art: as long as in use, due to
Tap is opened, cold water just will unavoidably pass through from the hot water facility of such as gas heater etc, and cause to fire immediately
The starting of heat, this frequent start-stop will obviously shorten the service life of hot water facility.
Summary of the invention
The purpose of this utility model is that: in view of the above-mentioned problems of the prior art, proposing that a kind of not only realize is opened
It is i.e. hot, convenient for transformation, and rationally avoid hot water facility frequent starting, to greatest extent energy-efficient hot water circulating device, give simultaneously
The hot-water heating system of the device is used out.
In order to achieve the above object, the hot water circulating device basic technical scheme of the utility model are as follows: including first,
Two mouthfuls and third mouth, the first connect second by the inner tube through circulating pump and the first on-off valve of series connection and the second on-off valve
Mouthful, the adapter tube between first on-off valve and the second on-off valve draws the branch pipe for connecing built-in heating liner water inlet, the heating
The outlet pipe of gallbladder is connected to third mouth.
Hot-water heating system using the utility model hot water circulating device include respectively by hot water line and cold water pipeline with
The water heater of first and second mouthful of connection, bridges multiple centre water spots between the hot water line and cold water pipeline, neighbouring
The cold water line branches of water heater go out cold water source pipeline, and neighbouring second mouthful of cold water pipeline is connect by branch line uses water spot nearby
One end, nearest another termination third mouth with water spot.
In use, not being difficult to guarantee realization instant-heating by the open-minded of circulating pump and pipeline；And when discharging water in short-term, pass through
The cut-off of the first on-off valve, the conducting of the second on-off valve are controlled, directly the hot water supply in heating liner is used, does not start hot water and sets
It is standby, rationally reduce the number of starts.It is controlled by the combination on-off of the first on-off valve and the second on-off valve, reduces heat source starting；
The first on-off valve of control on demand conducting simultaneously, the cut-off of the second on-off valve can improve hot water using circulating pump as pressurization pump operation
Supply pressure.
The utility model further improves, and the adapter tube between first on-off valve and the second on-off valve is drawn through flowing
Meter connects the branch pipe of built-in heating liner water inlet.
It is that the signal output end of the flowmeter connects the first on-off through control circuit that the utility model, which further improves,
The controlled end of valve and the second on-off valve and circulating pump.
Detailed description of the invention
Fig. 1 is the pipeline heat insulation status diagram of the utility model embodiment one.
Fig. 2 is that the nearest of the utility model embodiment one uses water spot normal pressure water state schematic diagram.
Fig. 3 is the nearest with water spot pressurization water state schematic diagram of the utility model embodiment one.
Specific embodiment
Embodiment one
The hot water circulating device of the present embodiment is integrated in Fig. 1 in shell shown in dotted line frame, which has first
1, second mouthful 2 and third mouth 3, first 1 are connect by the inner tube of circulating pump P and the first on-off valve A and the second on-off valve B that connects
Second mouthful 2, the adapter tube between the first on-off valve A and the second on-off valve B, which is drawn, connects built-in heating liner water inlet i's through flowmeter L
The outlet pipe o of branch pipe, heating liner connects third mouth 3.The signal output end of flowmeter L meets the first on-off valve A and through control circuit
The controlled end of two on-off valve B and circulating pump P.
Using the hot-water heating system of the hot water circulating device as shown in Figure 1, including passing through hot water line H and cold water pipeline respectively
C and first 1 and second mouthful of 2 gas heater being connected to, bridge multiple centre water between hot water line H and cold water pipeline C
The cold water pipeline C bifurcated of point A1, A2, neighbouring water heater go out to be connected to the cold water source pipeline of water, neighbouring second mouthful 2 of cold water pipeline
The one end for using water spot B1 nearby is connect by branch line, uses another termination third mouth 3 of water spot B1 nearby.
When work, control circuit can realize the switching control of following various states according to the signal of flowmeter:
As shown in Figure 1, control the first on-off valve A and the second on-off valve B is simultaneously turned on, pump operating cycle, heat when not having to water
Hydrophone starting, pipeline heat insulation circulation, no matter intermediate duct how long, can guarantee each centre water spot A1, A2 open when open i.e.
Heat.
As shown in Fig. 2, when using water on a small quantity with water spot B1 nearby, the first on-off valve A of control cut-off, the second on-off valve B conducting,
Circulating pump stops, and water heater does not start, and is supplied in time nearby by the hot water stored in heating liner with water spot B1.
As shown in figure 3, when largely using water with water spot B1 nearby, the first on-off valve A of control conducting, the second on-off valve B cut-off,
Circulating pump can open operation at this time, and water heater starting guarantees enough water supply if circulating pump unlatching can play pressurization.
Experiment shows that compared with prior art, the present embodiment has the following obvious advantages:
1) the combination control of the first on-off valve and the second on-off valve and circulating pump, reliably realizes instant-heating；
2) no setting is required water return pipeline, installation and transformation are very easy；
3) small flow discharges water directly with the hot water supply in heating liner in short-term, does not start water heater, substantially reduces its starting
The frequency effectively extends service life；
4) booster pump can be also doubled as when circulating pump is opened, and increase hot water supply pressure.
