Abstract
The utility model relates to an outdoor frost crack prevention device for a water pipe of a solar water heater. The frost crack prevention device adopts the structure that a vertical water pipe is inserted into the bottom from the top surface of the water storage tank of the solar water heater, and the upper end of the vertical water pipe is connected with an upper tee joint; the horizontal end of the upper tee joint is connected with the water pipe, the lower end of the water pipe is connected with an indoor water valve of a user, the upper end of the upper tee joint is connected with the output end of a one-way valve through a vertical short pipe, the input end of the one-way valve is connected with a breathing pipe, and the lower end of the breathing pipe is connected with an indoor air valve of the user; and an original upper air outlet hole of the water storage tank of the water heater is connected with a lateral tee joint through a transverse short pipe, the upper end of the lateral tee joint is connected with a vertical breathing short pipe, and the lower end of the lateral tee joint is connected with an overflow pipe leading to the interior of the user's room. When the outdoor temperature is below zero, and the solar water heater is not in use, the user starts the indoor air valve as soon as the water storage tank is filled with water, so that the top of the water pipe is communicated with the atmosphere, and all the water in the water pipe flows out instead of being stored therein, so as to prevent the water pipe from frost cracking.
Description
Technical field
The utility model relates to a kind of solar water heater auxiliary equipment, and the outdoor upper and lower conduit of particularly a kind of solar water heater is prevented the bursting by freezing device.
Background technology
At northern area, the outdoor temperature in winter has some months all to be in subzero, often causes the outdoor upper and lower conduit bursting by freezing of solar water heater, makes users dare not use solar water heater in the winter time, has hindered applying of solar water heater.
Summary of the invention
The purpose of this utility model has provided a kind of anti-bursting by freezing device of the outdoor upper and lower conduit of solar water heater that prevents the bursting by freezing of the outdoor upper and lower conduit low temperature of solar water heater.
For solving the problems of the technologies described above, the technical solution of the utility model is: the outdoor upper and lower conduit of a kind of solar water heater is prevented the bursting by freezing device, its vertical water pipe inserts the bottom from the end face of described solar water heater storage water tank, and vertical water pipe sealing is installed in the end face of solar water heater storage water tank; Vertical water pipe upper end connects the top threeway; The horizontal ends of top threeway is connected with upper and lower conduit, and the indoor water valve of the lower end of upper and lower conduit and user is connected; The upper end of top threeway is connected with the output of check valve by vertical short tube, and the input of check valve is connected with breather pipe, and the indoor air valve of the lower end of breather pipe and user is connected; The original paddle hole plug shutoff down of described solar water heater storage water tank, the original venthole of going up of solar water heater storage water tank is connected with the side threeway by lateral stub, the upper end of side threeway is connected with vertical ventilation short tube, and the lower end of the side threeway overflow pipe indoor with leading to the user is connected.
The beneficial effects of the utility model are: when outdoor temperature is in subzero, and when not using solar water heater, after the user gives the solar water heater storage water tank filling up water, open the indoor air valve of user immediately, the upper and lower conduit top communicates with atmosphere, water in the upper and lower conduit all flows out under the atmospheric pressure effect of top, can not store water in the upper and lower conduit, also just can not bursting by freezing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment is as shown in Figure 1: the outdoor upper and lower conduit of a kind of solar water heater is prevented the bursting by freezing device, and its vertical water pipe 2 inserts the bottom from the end face of solar water heater storage water tank 1, and vertical water pipe 2 sealings are installed in the end face of solar water heater storage water tank 1.Vertical water pipe 2 upper ends connect top threeway 3, and the horizontal ends of top threeway 3 is connected with upper and lower conduit 11, and the indoor water valve 14 of the lower end of upper and lower conduit 11 and user is connected.The vertical short tube 4 of the upper end of top threeway 3 by 30 centimeters long is connected with the output of check valve 5, and the input of check valve 5 is connected with breather pipe 12, and the indoor air valve 13 of the lower end of breather pipe 12 and user is connected.When normally using solar water heater, the indoor air valve 13 of user is closed.When outdoor temperature is in subzero, and when not using solar water heater, the user opens the indoor air valve of user 13 after giving solar water heater storage water tank 1 filling up water immediately; Air enters vertical short tube 4 by breather pipe 12 through check valve 5, and the top of upper and lower conduit 11 is communicated with atmosphere, and the water in the upper and lower conduit 11 all flows out under the atmospheric pressure effect of top; Because upper and lower conduit 11 tops are higher than solar water heater storage water tank 1, the water in the solar water heater storage water tank 1 can not flow in the upper and lower conduit 11; Can not store water in the upper and lower conduit 11, also just can not bursting by freezing.If when using solar water heater, close the indoor air valve of user 13 earlier, open 1 water filling of water supply valve door thermotropism water heater storage water tank again, make be full of water in the upper and lower conduit 11 after, open drainage valve again, it is indoor that the water in the solar water heater storage water tank 1 just can flow into the user along upper and lower conduit 11.Check valve 5 can only be to vertical short tube 4 air inlets, and oppositely water outlet.
Solar water heater storage water tank 1 original paddle hole down plug 6 shutoff, solar water heater storage water tank 1 original venthole of going up is connected with side threeway 9 by lateral stub 7, the upper end of side threeway 9 is connected with 10 centimeters long vertical ventilation short tube 8, as discharging the steam that water heater produces in using.The lower end of side threeway 9 overflow pipe 10 indoor with leading to the user is connected, and the user opens the water supply valve door when solar water heater storage water tank 1 water filling, if overflow pipe 10 there are flowing out, signal solar water heater storage water tank 1 water is full, and the user closes the water supply valve door immediately.
