Abstract
The utility model relates to a water heater holding water box that non - pressure -bearing heating pressure -bearing was used, including positive displacement water container for water heater, positive displacement water container for water heater's the pipeline and atmosphere intercommunication of upper portion through taking the normally open solenoid valve, positive displacement water container for water heater's side is connected with inlet tube and outlet pipe respectively, one end from neighbouring positive displacement water container for water heater on the inlet tube is equipped with first check valve and normally -closed solenoid valves in proper order, one end from neighbouring positive displacement water container for water heater on the outlet pipe is equipped with second check valve, water flow switch, third check valve and hot water valve in proper order. The utility model discloses a function of pressure -bearing water tank is realized to the positive displacement water tank of low -cost high performance -price ratio, has both inherited the advantage of non - pressure -bearing water tank, and the top water that has the pressure -bearing water tank simultaneously again goes out the advantage of water, whole holding water box's technique is simple reliable, and non - pressure -bearing thermal -arrest state is lower to water tank technical requirement, and the cost is also lower, and life is longer moreover.
Description
Technical field
This utility model relates to and belongs to field of water heaters, a kind of water heater heat preservation water tank realizing the use of non-pressure heating pressure-bearing.
Background technology
At present, conventional solar water heater is usually and uses pressure-bearing or non-pressure water-heater system；For non-pressure water-heater system, for open system, water-out manners is water falling type (water tank is installed and is higher than with water spot) or uses water pump supercharging water-out manners, and moisturizing is single water supplementing method；And for pressure-loaded water-heater system, be to utilize cold water to eject hot water, with tap water homology with pressure, with while sending hot water, tap water automatically into, there is not moisturizing problem and discharge pressure problem, but there is the problem that mixed gentle rate of thermal water utilization is the highest.Comparatively speaking actual in the heating process of hot water, the water in attemperater heats up and expands, and pressure-loaded water-heater system possesses higher bearing capacity, but the cost of pressure-loaded water-heater system is the highest, and technology requires the highest.
In sum, the problem that conventional water heaters exists is as follows: the most non-pressure water-heater system is with low cost, but there is moisturizing and the problem of water outlet supercharging；Although 2. pressure-loaded water-heater system does not exist moisturizing and water outlet boost issues, but there is High Temperature High Pressure during thermal-arrest, hot water facility is proposed requirements at the higher level, causes production cost higher.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the non-pressure water-heater system of existing independence and the deficiency of pressure-loaded water-heater system, design provides a kind of brand-new attemperater, integrate pressure-bearing and the advantage of non-pressure water-heater system, not only achieve the non-pressure state of heating process but also achieve pressure-bearing use.
It is designed with following scheme for this this utility model:
The water heater heat preservation water tank that a kind of non-pressure heating pressure-bearing uses, including displacement water-tank, the top of described displacement water-tank is by the pipeline of band normally open solenoid valve and atmosphere, the side of described displacement water-tank is connected to water inlet pipe and outlet pipe, and described water inlet pipe is sequentially provided with the first check-valves and normally closed solenoid valve from one end of neighbouring displacement water-tank；From one end of neighbouring displacement water-tank, it is sequentially provided with the second check-valves, water flow switch, the 3rd check-valves and hot-water valve on described outlet pipe.
The beneficial effects of the utility model are:
This utility model uses the positive displacement water box of low cost high performance-price ratio, it is achieved the function of press-bearing water tank, the advantage both having inherited non-pressure water tank, has again the advantage of the top water water outlet of press-bearing water tank simultaneously；Under pressure-bearing use state, cold water ejects hot water, has both achieved automatic feeding water, has achieved again automatic outletting；The technology of whole attemperater is simple and reliable, and water tank technology is required lower by non-pressure collection Warm status, and cost is the lowest, and service life is longer.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further, wherein:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The water heater heat preservation water tank used with reference to a kind of non-pressure heating pressure-bearing shown in Fig. 1, including displacement water-tank 1, the top of displacement water-tank 1 is by the pipeline 3 of band normally open solenoid valve 4 and atmosphere, the side of displacement water-tank 1 is connected to water inlet pipe 5 and outlet pipe 6, and water inlet pipe 5 is sequentially provided with the first check-valves 7 and normally closed solenoid valve 8 from one end of neighbouring displacement water-tank 1；From one end of neighbouring displacement water-tank 1, it is sequentially provided with the second check-valves 9, water flow switch the 10, the 3rd check-valves 11 and hot-water valve 12 on outlet pipe 6.
Operation principle of the present utility model is as follows: when water heater (comprising any type of water heater) is in heating, normally closed solenoid valve is closed, and open to atmosphere normally open solenoid valve is in opening, connects with air；So tap water and water tank is disconnected, and hot-water valve is closed, and water tank not pressurized is in non-pressure state, hot water expands after being heated, and owing to normally open solenoid valve communicates with air, water tank is not by any pressure, safe and reliable, heated condition or etc. state to be used achieve non-pressure form.
And when using hot water conditions, open hot-water valve, outlet pipe release pressure, drive water flow switch energising output switching signal, connect normally open solenoid valve (being allowed to be in close valve state), also connecting normally closed solenoid valve (being allowed to be in opening), tap water enters displacement water-tank from water inlet pipe, and hot water is ejected use simultaneously；It is in close valve state after being energized due to normally open solenoid valve, hot-water heating system is made at once to be become pressure bearing system (being actually level pressure) from open system, achieve top water water outlet, once close hot-water valve, water flow switch power-off, making the power-off the most therewith of normally open solenoid valve and normally closed solenoid valve, normally open solenoid valve connect with air, system is in non-pressure state at once.Due to the effect of second, third check-valves, make the line segments pressure store between two check-valves residing for water flow switch, to guarantee the unlatching of water flow switch.
The above; it is only the preferable detailed description of the invention of this utility model; but this utility model protection domain is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Therefore this utility model protection domain is as the criterion with the protection domain of claims.
