Description
Technical field
The utility model relates to a kind of water pipe anti-freezing structure, is specifically related to the water pipe anti-freezing structure that is connected with outdoor boiler.
Background technology
Teat pump boiler, air conditioner and water heater, electric heater, solar water heater etc. heat the wetting system system at present, when its hot water storage tank is set at when outdoor, there is antifreeze problem in winter in the conduit component of the outdoor section of whole water circulating system, as properly not taking the anti-freeze measure, after outdoor environment temperature is lower than 0 ℃, can cause the bursting by freezing of water pipe and associated components, bring loss to the user.
In the prior art, anti-freezing method commonly used has: adopt various electric heating thermal insulation methods, or employing water pump low temperature endless form, maybe can adopt when the water temperature in the pipeline is lower than certain value cut-off to connect discharges water etc., the shortcoming of said method is, need to be equipped with a cover control system and monitor water temperature at any time and in time start equipment or parts such as electric heater, water pump and magnetic valve, but also can waste energy and water resource.Having is exactly to add anti-icing fluid again, or adopts other anti-freezing method such as Artificial Control, and these methods also exist system's design and the complicated shortcoming of operation.Simultaneously, many control measure depend on the normal of power supply, if outage suddenly occurs then owing to can't monitor, may cause the freezing of parts such as water pipe and water pump thus.
The utility model content
The purpose of this utility model is to overcome defective of the prior art, designs a kind of anti-freezing structure that makes the outdoor hot water device of the water formation Natural Circulation in outside water box and the pipeline.
For achieving the above object, the technical solution of the utility model is to adopt a kind of anti-freezing structure of outdoor hot water device, comprise boiler, the upper end of described boiler is connected with outlet pipe, the lower end of described boiler is connected with water inlet pipe, between described outlet pipe and described water inlet pipe, be connected with the auxiliary circulation pipe, on described auxiliary circulation pipe, check valve is housed, the inlet of described check valve is connected an end of the auxiliary circulation pipe that is connected with described outlet pipe, the outlet of described check valve is connected an end of the auxiliary circulation pipe that is connected with described water inlet pipe, and the vertical center of described boiler is lower than the vertical center of described auxiliary circulation pipe.
Wherein, described auxiliary circulation pipe is set at indoor, or is set at outdoor position near body of wall.
Wherein, on described boiler, all be enclosed with heat-insulation layer with the appearance of described water inlet pipe appearance, outlet pipe appearance, auxiliary circulation pipe.
Wherein, described heat-insulation layer is the rock wool or the mineral wool of 10～25mm thickness.
Wherein, the vertical center difference in height of the vertical center of described boiler and described auxiliary circulation pipe is 100～1000mm.
Wherein, described boiler be Teat pump boiler or or air conditioner and water heater in water tank, described water tank is the water jacket that is installed on compressor and/or the condenser.
Wherein, described boiler is the water tank in the solar water heater.
Wherein, by the water inlet pipe of described boiler, through boiler to described outlet pipe, again to the closed circuit that is constituted between the described auxiliary circulation pipe if be provided with valve, stop under the heated state at described boiler, described valve all is positioned at the state of unlatching.
Operation principle of the present utility model is, because hot water in outdoor boiler or hot water jacket is when compressor operation or by electrical heating the time or by solar energy heating the time, water temperature in the boiler is heated to more than 50 ℃, when firing equipment after the landing of the out of service or sun, because the insulation effect of heat-insulation layer, the water in the water tank also will keep the high water temperature of long duration, and the water yield that remains in the water pipe is less, water temperature will reduce faster, in the winter time water temperature even can drop to below 0 ℃.But if after between the outlet pipe of boiler and water inlet pipe, being connected auxiliary circulation pipe and check valve, just constituted a closed circuit between the outlet pipe of boiler and water inlet pipe and the boiler, because the water temperature in the auxiliary circulation pipe is low, density is more greatly that relative weight will be heavier, and the water level center in the auxiliary circulation pipe is higher than the water level center in the water tank.Therefore, the water in the auxiliary circulation pipe will flow downward, because the water that is provided with in the auxiliary circulation pipe of check valve also can not flow backwards.Because the water temperature in the boiler is higher, and density is less, and relative weight can be lighter, therefore, the hot water in the water tank will flow out in outlet pipe again.Make the water in boiler, outlet pipe, auxiliary circulation pipe, the water inlet pipe form flowing of automatic circulation thus.Though the flow of above-mentioned circulation is less, this flow can guarantee to make that the water in the water pipe all the time can be frozen, as long as water and the water in the water pipe in the water tank also exist temperature difference, what above-mentioned circulation will not stop always goes on.Because the water yield in the water tank is more, the water yield in the water pipe is less, above-mentioned water circulation will be kept the quite a long time, and people may heat the water in the water tank again before above-mentioned water circulated in and stops automatically, or outdoor environment temperature has been elevated to more than 0 ℃.Therefore the water in the water pipe will be frozen never, if no longer be used in the water in the boiler is long-time, the valve open of boiler lower end all can be emitted the water in boiler and the water pipe, can prevent that so also the water in the antipriming pipe is frozen.
Advantage of the present utility model and beneficial effect are:
1, under equipment or manually operated condition such as do not adopt water pump, electrical heating, anti-icing fluid, discharge water, reached the purpose of the Natural Circulation anti-freeze of water.
2, this anti-freezing structure does not rely on electric power, does not depend on water pump and magnetic valve etc. and exist the execution unit of potential faults can realize that the water in the outdoor water pipe prevents to freeze, and promptly safety is reliable again to experimental results show that this anti-freezing structure.
3, whole anti-freeze has characteristics simple in structure, easy to assembly, long service life.
4, almost not having production cost, only to need to insert in original device the expense of a vertical auxiliary circulation pipe and check valve, repacking lower, and can save the energy and water resource.
5, the adaptability to all types of user and service condition is strong, not only is suitable for the hot water supply system of Teat pump boiler and air conditioner and water heater, and is suitable for similarly having the hot water supply system such as electric heater, solar water heater of outdoor hot-water line.
