Abstract
The utility model relates to an exhaust device of a solar thermal collector, which comprises an exhaust tank; the lower end of the exhaust tank is communicated with a water return pipeline of a solar thermal collector by a short pipe, the upper end of the exhaust tank are respectively connected with two gate valves by two sections of short pipes, and the two gate valves are respectively provided with two exhaust valves; and on the water return pipeline of the solar thermal collector, a pair of serially-connected one-way check valves are connected behind the exhaust tank by the short pipes. Compared with the prior art, the exhaust device of the solar thermal collector has a simple structure, is convenient to use and low in production cost, thoroughly solves the problem of air resistance of thermal collectors in a solar hot water bathing system, and greatly improves the reliability of the whole system.
Description
Technical field
The utility model belongs to the solar facilities technical field, relates to a kind of exhaust apparatus, especially a kind of exhaust apparatus to solar thermal collector.
Background technology
In the prior art, the water return pipeline of solar thermal collector is as shown in Figure 1, and solar thermal collector is installed on the roof flooring 2, and its water return pipeline 1 is as shown in the figure, finds that in use pressure of return water is higher, and pressure reaches 2.5Mpa.Because this solar energy system designs for non-bearing type, the highest pressure that bears of pipeline is 0.1Mpa, thereby causes the header distortion of solar energy, solar energy vacuum tube and the large-scale water leakage of header coupling part.Through analyzing, cause too high former of pressure of return water to cause vapour lock, thereby system pressure is constantly raise because the return pipe exhaust is not smooth, pipeline leaks seriously.
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art; A kind of exhaust apparatus of solar thermal collector is provided; It is almost nil that it can make on the pipeline of solar thermal collector pressure of return water be decreased to, thereby make hot water reflow tank smoothly, accomplishes circulation.
The purpose of the utility model solves through following technical scheme:
The exhaust apparatus of this solar thermal collector; Comprise an exhaust tank; The lower end of said exhaust tank is communicated with the water return pipeline of solar thermal collector through short tube, and the upper end of said exhaust tank is connected with two gate valves respectively through the two-section short tube, on said two gate valves two air bleeding valves is installed respectively; On the water return pipeline of solar thermal collector, also be connected with the unidirectional stop valve of pair of series in the rear of exhaust tank through short tube.
One section steel pipe that above-mentioned exhaust tank is shut with steel plate by upper and lower side constitutes, and on the steel plate of steel pipe upper and lower side, offers in order to connect the perforate of short tube.
The utility model compared with prior art, and is simple in structure, easy to use, and cost is with low cost, thoroughly solved the vapour lock problem of heat collector in the solar hot-water bath system, improved the reliability of whole system again greatly.
Description of drawings
Fig. 1 is the backwater pipe structure figure of solar thermal collector in the prior art;
Fig. 2 is the exhaust apparatus structural representation of the solar thermal collector of the utility model.
Wherein: 1 is water return pipeline; 2 is the roof flooring; 3 is gate valve; 4 is air bleeding valve; 5 is unidirectional stop valve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 2; The exhaust apparatus of the solar thermal collector of the utility model; Comprise an exhaust tank P; The lower end of this exhaust tank P is communicated with the water return pipeline 1 of solar thermal collector through short tube, and the upper end of exhaust tank P is connected with respectively on 3, two gate valves 3 of two gate valves through the two-section short tube two air bleeding valves 4 are installed respectively; On the water return pipeline 1 of solar thermal collector, also be connected with the unidirectional stop valve 5 of pair of series in the rear of exhaust tank P through short tube.
In the preferred embodiment of the utility model, exhaust tank P adopts one section steel pipe to be welded, and its one section steel pipe being shut with steel plate by upper and lower side constitutes, and on the steel plate of steel pipe upper and lower side, offers in order to connect the perforate of short tube.
In sum, the exhaust apparatus of the utility model has thoroughly solved the vapour lock problem of heat collector in the solar hot-water bath system after using in the solar hot-water bath system, and it is not only simple in structure, pipe arrangement is succinct, and reliable operation.Make pressure of return water almost nil, make hot water reflow tank smoothly, accomplish circulation.The utlity model has good social and economic benefit.
