Abstract
The utility model relates to an antifreezing device for pipe fittings of a solar energy heater, which comprises a first switch component arranged on the upper part of the pipe fittings of a cistern and auxiliary pipe fittings communicated respectively with the pipe fittings and the cistern. The auxiliary pipe fittings are arranged with a second switch component. By utilizing the atmospheric pressure, the antifreezing device drains the water in the pipe fittings to solve the problem of the freeze of the pipe fittings, and the cost is unlikely to increase largely.
Description
Technical field:
The utility model relates to a kind of pipe fitting defroster that is used on the solar water heater.
Background technology:
Prior solar water heater generally includes water storage container and is used to heating and the coupled logical thermal-collecting tube of the interior liquid of this water storage container, and be used to water storage container to carry the pipe fitting of heated medium such as water, and be separately installed with water supply valve and outlet valve in the porch of this pipe fitting or away from an end of water storage container.This kind solar water heater is that water storage container and thermal-collecting tube add water by water supply valve and pipe fitting at first when work, when the water in the water storage container is heated the back and need makes water, will be heated water by the mode of opening outlet valve and discharge.But, on described in the whole process of water, heating and draining, be to be in water-filled state all the time in the pipe fitting, and solar water heater together with a part of pipe fitting be installed in all that the sun can shine as roof or other occasion of not blocking, so when environment temperature was lower than zero degree, the water in the pipe fitting was easy to freeze, and pipe fitting freezes and can directly influence water heater and normally use, and severe patient can cause the pipe fitting bursting by freezing; In addition, pipe fitting in the water heater of said structure is connected with water storage container and thermal-collecting tube, even if the outlet valve that will be installed on the pipe fitting is opened, because of being subjected to the influence of siphonage, have only the water of all getting rid of in the rear tubular member when the water in water storage container and the thermal-collecting tube just can discharge, so the water heater of said structure itself can not solve the pipe fitting problem that freezes.
At the problems referred to above, Chinese patent has been announced the improvement technology that a kind of name is called " antifreezing solar energy water pipe " for No. 1151350, same pipe fitting of the same employing of the last water of this solar water heater and water vent is just at pipe fitting inner insertion heat pipe or at its outside winding heat pipe.Its meaning is to want to utilize heat pipe to solve the problem that pipe fitting freezes.Since in described pipe fitting or outside increase the raising that heat pipe can directly cause its cost of manufacture on the one hand, give to install and make and all bring difficulty, heat pipe needs a stable thermal source to provide support on the other hand.
Summary of the invention:
The purpose of this utility model provides a kind of mode of utilizing atmospheric pressure to get rid of water in the pipe fitting and solves the freeze solar water heater pipe fitting defroster of problem of under cryogenic conditions pipe fitting.
The solar water heater pipe fitting defroster that the utility model proposed comprises first switch block that is installed in water storage container pipe fitting top and the auxiliary pipe fitting that is connected with pipe fitting and water storage container respectively, on this auxiliary pipe fitting the second switch parts is installed.
Described pipe fitting is connected with the upper end of water storage container, and auxiliary pipe fitting is connected with the below of water storage container end.
Described first switch block and second switch parts constitute by magnetic valve.
Described pipe fitting comprises vertical vertical tube spare in the water storage container and the L shaped pipe fitting that is connected with this vertical tube spare of inserting along the water storage container top, in the upper end of vertical tube spare first switch block is installed.
The solar water heater pipe fitting defroster that the utility model proposed adopts a vertical tube spare by the opening of first switch block control, after first switch block is opened, utilize atmospheric pressure the water in the pipe fitting can be discharged, so, this device can solve the pipe fitting problem that freezes, and it is simple in structure; Simultaneously, first switch block and second switch parts constitute by magnetic valve, and magnetic valve can be handled it and open or close state by shaking the control or the mode of button, so, use the interior very convenient operation of water of this device discharging pipe fitting, do not increase how many costs.
Description of drawings:
Accompanying drawing 1 is the surface structure schematic diagram that the utility model proposes an embodiment of solar water heater pipe fitting defroster.
The specific embodiment:
Referring to Fig. 1, this figure provides the overall appearance structure that the utility model proposes an embodiment of solar water heater pipe fitting defroster.This defroster comprises the pipe fitting 1 and first switch block 2 substantially, and second switch parts 3.
Pipe fitting 1 comprises vertical tube spare 11 that vertically inserts from the top in the water storage container 4 and the L shaped pipe fitting 12 that is connected with this vertical tube spare 11, and the auxiliary pipe fitting 13 that is connected with the side end of water storage container 4.Wherein, the top of vertical tube spare 11 is open ends 14, first switch block 2 is installed between open end 14 and L shaped pipe fitting 12, and on auxiliary pipe fitting 13 second switch parts 3 is installed.The lower end of L shaped pipe fitting 12 is separately installed with water supply valve 5 and outlet valve 6 by three-way pipe 15.Described first switch block 2 and second switch parts 3 can be made of magnetic valve, and the mode of control electromagnetic valve switch can adopt shakes control formula or button (because of the magnetic valve of these two kinds of control modes belongs to prior art, not providing concrete structure among the figure).
In use, earlier by water supply valve 5 and pipe fitting 1 water filling in water storage container 4, after being filled with, opens in the water in the water storage container 4 first switch block 2 and outlet valve 6, can produce atmospheric pressures to vertical tube spare 11 and L shaped pipe fitting 12 respectively after allowing air enter from the open end 14 of vertical tube spare 11, the water that this air with pressure can hinder in the vertical tube spare 11 on the one hand flows out through pipe fitting 1, water in the L shaped pipe fitting 12 can be discharged through outlet valve 6 on the other hand, after the water emptying in the L shaped pipe fitting 12, close first switch block 2 and outlet valve 6 again; And in need using water storage container 4 be heated water the time, open second switch parts 3 and outlet valve 6 earlier, allow water storage container 4 interior hot water flow out through auxiliary pipe fitting 13, and the upper end to L shaped pipe fitting 12 when water flows produces negative pressure, and then water also can flow out through it when the residual air in it drawn, and when confirming that L shaped pipe fitting 12 normally during draining, can cut out second switch parts 3, in order to avoid cause waste of electric energy.
