The pressure release pipe body is arranged on the water inlet and outlet pipe body; the gate valve can control the opening and failure of siphon action, to empty a water pipe, so as to effectively prevent the water pipe from bursting.
Description
Technical field
The utility model relates to a kind of solar water heater auxiliary equipment, relates in particular to a kind of built-in antifreezing solar energy emptier.
Background technology
Solar water heater is one of the most successful product of field of solar energy utilization, and its energy-conserving and environment-protective, easy to use are safe and reliable, become one of equipment of family's indispensability.But solar water heater in use, because storage tank is arranged at outdoorly, wherein the part water pipe is in naked state, freezes in regular meeting runs into water pipe even the phenomenon of water pipe from freezing crack in winter.In order to prevent the generation of this phenomenon, the method for using generally is with the water emptying in the exposed water pipe now, perhaps at the outer surface of water pipe electric heater unit is installed.This method that electric heater unit is installed at the outer surface of water pipe is that water pipe is heated, the water freezing in the anti-antipriming pipe, thus make not bursting by freezing of water pipe guarantee that the resident normally uses, this method has many shortcomings, it not only wastes electric energy, and dangerous, and is accidents caused easily; And the water in the water pipe is carried out this method of emptying, and generally need control by magnetic valve, rely on electronic emptying, magnetic valve does not rise and close winter, and is malfunctioning easily, so result of use is undesirable.
The utility model content
Technical problem to be solved in the utility model provides a kind of built-in antifreezing solar energy emptier, and emptying automatically prevents water pipe from freezing crack.
For solving the problems of the technologies described above, the technical solution of the utility model is: built-in antifreezing solar energy emptier, comprise inverted U-shaped Inlet and outlet water body, described Inlet and outlet water body is arranged on solar water container inside, described Inlet and outlet water body has first openend that is positioned at solar water container inside, with second openend that stretches out described solar water container outside, the top of described Inlet and outlet water body is connected with the pressure release body, and described pressure release body is provided with gate valve.
As a kind of improvement, the junction of described pressure release body and described Inlet and outlet water body is provided with check-valves.
As further improvement, the end that described Inlet and outlet water body is arranged on solar water container inside is provided with screen pack.
Owing to adopted technique scheme, be set to inverted U-shapedly by the Inlet and outlet water body, can realize siphon, the pressure release body is set on the Inlet and outlet water body, on the pressure release body, gate valve is set, can controls air by gate valve and enter the Inlet and outlet water body, thus the unlatching and the inefficacy of control siphon action.After waterborne expiring, stop to go up water, open gate valve, air enters in the Inlet and outlet water body from the top, and the water in the body of second open end side of Inlet and outlet water body is realized emptying owing to self gravitation flows out; During water, closing gate valve, last water is after filling water in the inverted U-shaped chamber of Inlet and outlet water body, stop to go up water, at this moment will form siphonage, the water in the solar water container can flow out automatically, and it is not only simple in structure, and be convenient to control, emptying is effective, can effectively prevent water pipe from freezing crack.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in the figure, built-in antifreezing solar energy emptier, comprise the Inlet and outlet water body 1 that is used for Inlet and outlet water, described Inlet and outlet water body 1 is inverted U-shaped, described Inlet and outlet water body 1 is arranged on solar water container 6 inside, described Inlet and outlet water body 1 comprises first openend 11, with one second openend 12, first openend 11 is arranged on the inside of solar water container 6, and be arranged on the bottom of solar water container 6, second openend 12 stretches out solar water container 6 outsides, can above water and water outlet by second openend 12; Solar water container 6 is provided with an overfall 7, can prevent hypertonia in the solar water container 6 by overfall 7, thereby guarantee to realize siphonage; Be connected with pressure release body 2 at the top of inverted U-shaped Inlet and outlet water body 1, described pressure release body 2 is provided with check-valves 3 with the junction of described Inlet and outlet water body 1, can stop aqueous reflux to advance in the pressure release body 2 automatically by check-valves 3.Described pressure release body 2 is provided with gate valve 4, and the effect of gate valve 4 is being communicated with of control outside air and Inlet and outlet water body 1.Open gate valve 4, outside air can enter in the U-shaped chamber of Inlet and outlet water body 1, thus the generation of blocking-up siphonage; Closing gate valve 4 with being communicated with of the U-shaped chamber of blocking-up outside air and Inlet and outlet water body 1, after filling water in the inverted U-shaped chamber of Inlet and outlet water body 1, will form siphonage.
The end of described Inlet and outlet water body 1 is provided with screen pack 5, and screen pack 5 is magnesium granules screen packs, can play anti-incrustation scale by screen pack 5, the anti-aging and purpose of purifying waste water.
Operation principle is as follows:
Last water, gate valve 4 is closed, and water enters solar water container 6 from Inlet and outlet water body 1, and this moment, check-valves 3 was subjected to the hydraulic pressure closure.
After waterborne expiring, stop to go up water, open gate valve 4, check-valves 3 is opened, and air enters in the Inlet and outlet water body 1 from the top, and the water in the body of second openend, 12 sides of Inlet and outlet water body 1 is realized emptying owing to self gravitation flows out.
During water, closing gate valve 4 is opened water supply valve, and last water after filling water in the U-shaped chamber of Inlet and outlet water body 1, stops to go up water, at this moment, utilizes siphon principle, and the water in the solar water container 6 can flow out automatically.
The utility model is not limited to above-mentioned concrete embodiment, for example, check-valves 3 is not set, and at this moment, pressure release body 2 directly stretches out solar water container 6 from the top of Inlet and outlet water body 1, also can reach similar purpose.
The utility model is simple in structure, and control is convenient, emptying automatically, thus prevent water pipe from freezing crack.
