Abstract
The invention discloses a bidirectional solar water heater which is provided with a straight heat collecting pipe (1) with dual openings; a water collecting tank (4) and a water supply tank (5) are respectively arranged at the upper opening and the lower opening of the heat collecting pipe (1). The bidirectional solar water heater is characterized in that the water through holes (2) of the water collecting tank (4) and the water supply tank (5) are respectively provided with a piston (3); the water through hole (2) is a horn shape; the shape of the piston (3) is matched with the shape of the water through hole (2); and the density of the material of the piston is equal to that of the water. The bidirectional solar water heater can quickly block the continuing loss of water in the water tank after the heat collecting pipe is broken, has simple structure, low cost and is convenient and practical.
Description
Technical field:
The present invention relates to a kind of solar water heater that is used to prevent the more than phenomenon of current when thermal-collecting tube is cracked.
Background technology:
Solar water heater is a photothermal converter, and thermal-collecting tube is the core of solar water heater, and the glass liner for vacuum flask of its structure such as same elongation is vacuum between the ectonexine.On the outer surface of inner glass tube, utilize special warfare to scribble spectral selective absorbing coating and be used for absorbing to greatest extent solar radiant energy.Through solar radiation, photon strikes coating, conversion of solar energy are heat energy, and water is from coating heat absorption, and temperature raises, and density reduces, and hot water moves upward, and heavy cold water descends, and hot water is positioned at top all the time, through microcirculation delivery in attemperater.Solar water heater intensification situation and ambient temperature relation are little, depend primarily on illumination.When opening any one tap, the hot water in the water heater just relies on the nature drop to flow out, and drop is big more, and hydraulic pressure is high more.Because the thermal-collecting tube of solar water heater is a glass material, broken under extraneous foreign matter effect easily, under the weather of cold, rupture, cause the water in the water tank to flow out, waste.
Summary of the invention:
The present invention is directed to the above-mentioned deficiency of prior art, provide a kind of thermal-collecting tube cracked after, can block the solar water heater that the water in the water tank continue to run off rapidly.
Technical solution of the present invention is: a kind of two-way solar water heater, be provided with the through-type thermal-collecting tube 1 of two openings, at the upper and lower opening place of thermal-collecting tube 1 header tank 4 and supply tank 5 are set respectively, the match 3 of living is set respectively at outlet pass 2 places of header tank 4 and supply tank 5, outlet pass 2 is horn-like, the shape and the outlet pass 2 of match 3 alive are complementary, and the material density of the match 3 of living equals the density of water.
In normal operation of the present invention following time,, the match 3 of living is suspended in outlet pass 2, and hot and cold water can free flow, when thermal-collecting tube 1 breaks, under the pressure effect of match 3 water header tank 4 and supply tank 5 in of living, is stuck in outlet pass 2 places, stops the water in the water tank to continue loss.The present invention is simple in structure, and is with low cost, convenient and practical.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiments of the invention.
Embodiment 1:
As shown in Figure 1, a kind of two-way solar water heater, be provided with the through-type thermal-collecting tube 1 of two openings, at the upper and lower opening place of thermal-collecting tube 1 header tank 4 and supply tank 5 are set respectively, at outlet pass 2 places of header tank 4 and supply tank 5 match 3 of living is set respectively, outlet pass 2 is horn-like, and the shape and the outlet pass 2 of the match 3 of living are complementary, the material density of match 3 alive equals the density of water, and it is that thing can suspend that the match 3 of then living does not need to be provided with other outer again.
Claims (1)
1. two-way solar water heater, be provided with the through-type thermal-collecting tube (1) of two openings, header tank (4) and supply tank (5) are set respectively at the upper and lower opening place of thermal-collecting tube (1), it is characterized in that: locate to be provided with respectively the match (3) of living at the outlet pass (2) of header tank (4) and supply tank (5), outlet pass (2) is horn-like, shape and the outlet pass (2) of matching (3) of living is complementary, and the material density of the match (3) of living equals the density of water.
