Description
Technical field
The present invention relates to a kind of solar water heater, specifically a kind of defroster and with the defroster too
Positive energy water heater.
Background technology
China's solar water heating system is mostly middle part and southern area using the area of Relatively centralized at present, and the big portion in the north
Region-by-region, the particularly very abundant the Northwest of daylight resource, but solar water service condition is unsatisfactory.Due to the sun
Energy hot-water heating system has portion of runner to be likely to result in solar heat-collection plate and its system if in outdoor, such as northerly winter
Pipeline freezes or bursting by freezing, solar energy system is damaged and ineffective.Therefore, want solar energy system and enter the north extensively

Top be provided with fixed component, the sealing gasket coordinated with the spilled water hole, the sealing gasket and the fixation are provided with described sleeve pipe
Temperature-sensing element bag is provided between part, for the temperature-sensing element bag with thermometer bulb seat supports on valve body, sealing gasket is located at temperature-sensing element bag
Bottom and thermometer bulb seat between；Reset element is additionally provided between the thermometer bulb seat and valve body.
Frost valve of the prior art is disposed in the outdoor on water-supply-pipe, when the temperature in environment is less than the temperature set, sense
Warm element thermometer bulb shrinks, and sealing gasket moves up with thermometer bulb seat in reset element effect, opens spilled water hole, lets out a small amount of current
Go out, avoid pipeline from freezing by continuous current, although the antifreeze valve arrangement is simple, the temperature-sensitive in the frost valve of prior art
Element senses are extraneous temperature, and because the temperature in the external world and the temperature of pipeline reclaimed water are possible to different, this in the application is anti-
The ambient temperature for freezing the unlatching that valve is set is 4 ± 1 DEG C, and now the water temperature in pipeline is likely to be 6 DEG C or higher, then now
Open valve and first-class with regard to even a whole day or the longer time the whole night in advance, not reaching antifreeze effect not only can also waste water
Resource, unnecessary waste and increase use cost are caused to user.Even if the opening temperature that frost valve is set is reserved
The temperature difference in pipe and outside pipe, but because the heat dispersion of metal tube is more stronger than air, it is possible to the temperature outside pipe than real in pipe
Border is consistent, or in pipe temperature than pipe outside temperature it is lower, it is therefore possible to occur having started to freeze in pipe, but the temperature outside pipe
Also on the temperature of setting, it is impossible to it is antifreeze to solar water heater progress in time, solar water heater is caused to damage.
The content of the invention
Therefore, the technical problems to be solved by the invention are that though defroster of the prior art can antifreeze in real time but knot

10 water hole lower surfaces, and the water hole diameter of valve body 10 is smaller than the diameter of sealing-plug 201, be restricted up to move again.
The shell of sensing rod for temperature 30 will press against packing ring and move down, while packing ring also press against limit spring 52 and shrink, completely can be with satisfaction
The displacement stroke of warm rod 30, displacement stroke will not be influenceed because shutoff valve is stopped behind the door, when temperature sensing material rises
Valve element is promoted to move up, the hollow elongated tubular 302 of the sensing rod for temperature moves down in the presence of back-moving spring, the setting of limit spring
Be in order to prevent the hollow elongated tubular 302 when the stress that the valve element is turned off antifreeze passage but back-moving spring still has after
It is continuous to be displaced outwardly.
The meeting shrinkage when the paraffin sensing water temperature of the inside of sensing rod for temperature 30 is less than 3 DEG C, the back-moving spring 50 of the inside of sensing rod for temperature 30
Valve rod 202 will be promoted, valve rod 202 promotes ball sealer also valve rod 202 can be promoted to move toward bottom offset, regulation spring 51, sealed
Plug 201 and valve rod 202 are fixed with screw-threaded coupling, also can and then be moved, and sealing-plug 201 can promote valve rod 202, sealing-plug
201 and valve rod 202 be tightly connected, sealing-plug 201 and valve rod 202 move down and will open the antifreeze passage of opening of valve body 10,
Now, the hot water in solar energy water tank will enter collecting plate and system pipeline, make in solar heat-collection plate and system pipeline
Water temperature rise, avoid water temperature from persistently reducing and solar heat-collection plate and pipe network occur and freezes and bursting by freezing, when in collecting plate and being
When road water temperature under the overall leadership is higher than 5 DEG C, prevents solar heat-collection plate and pipe network freezes and the device of bursting by freezing is closed automatically, stop draining.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
