Description

The automatic emptying device of formula falls into water
Affiliated field
The utility model relates to a kind of drowning formula solar energy equipment, is used to realize daily solar energy emptying and once the automatic emptying device of drowning formula of opening the hot water supply.
Background technology
Solar energy emptying and be the knotty problem that this area exists for many years once opening hot water, the mode that solves with regard to its technology itself is also a lot, cost is low, two key elements of good reliability are relatively more difficult but will take into account simultaneously, provide the full emptying solar energy equipment of forming with whole frame for movements of drowning formula in the applicant's China's application formerly 200520082345.2, the evacuation structures that has proposed a kind of float-ball type in this device can address the above problem effectively.But finding in actual use that this structure still has needs improvements, makes structure seem complicated as the existence of two ball floats, has increased the resistance of current, and the sealing of ball float is difficult to guarantee well when using for a long time.
Summary of the invention
In order to overcome the problems referred to above that exist in China's application 200520082345.2, the purpose of this utility model provides the automatic emptying device of a kind of drowning formula.Its resistance to water-flow is little, good airproof performance, simple in structure.
The technical solution of the utility model is: the automatic emptying device of this drowning formula, comprise lower intake, go up intake tunnel, and and the air inlet storehouse with unidirectional activity shutoff of the pipeline connection at lower intake place, the bottom in the air inlet storehouse of activity shutoff is activity shutoff and air inlet, and the top in the air inlet storehouse of activity shutoff is communicated with the pipeline at lower intake place by inlet channel; Last intake tunnel is communicated with solar water container, lower intake is communicated with makes water pipe, lower intake and last intake tunnel pass through pipeline connection, it is characterized in that described lower intake is communicated with by U type sealing sump with last intake tunnel, one side of U type sealing sump is communicated with lower intake, and opposite side is communicated with upward intake tunnel.
Further program of the utility model is: described lower intake is communicated with U type sealing sump by right pipeline, the right mouth of a river, goes up intake tunnel by the left mouth of a river, left sump, the connection of left pipeline of right sump, U type sealing sump bottom.
Further program of the utility model can also be: the pipeline at described lower intake place directly is communicated with the right sump of U type sealing sump, and the left mouth of a river, left sump, the left pipeline of U type sealing sump bottom are communicated with goes up intake tunnel.
Further program of the utility model can also be: be the water-stop of raising activity shutoff, described inlet channel connects a high bit port, and the other end of this high bit port is curved down to be communicated on the pipeline at lower intake place.
The last intake tunnel of this device directly is connected with solar energy, and the position of connection can be in the bottom or the water tank side of water tank, and lower intake is connected with making water pipe, and Inlet and outlet water uses same pipeline.When to water tank water intake, water enters U type sealing sump, enters water tank by the left mouth of a river, left pipeline and last intake tunnel through pipeline from following inlet and outlet pipe lines.After water inlet finishes, as with the water emptying in the pipeline, only need the switch that control water tank air enters cuts out, enter owing to stopping air in the water tank, water is carved slightly and promptly can be stopped to flow out, open the effluent switch in the pipeline this moment, because the gravity of water, water can be let out under the nature, and the activity shutoff in the storehouse of air inlet is simultaneously picked up because of negative pressure, air just enters down access way along air inlet and inlet channel, thereby with the automatic emptying of the water in the water pipe.In non-freezing season, the water in the upper hose need not emptying at once, at the last water that finishes in the later time, use cold water as need, only need open and use threshold switch, the cold water in the pipe can flow out (emptying) automatically, till water in pipe used up (emptying end), the water in the pipe was not wasted at all.
Above-mentioned evacuation procedure is only at the water in the pipeline, and the water in the water tank is motionless.
After emptying was finished, the air in the pipeline did not hide as there being retaining, will enter water tank, caused intermittent outflow of water in the water tank.For fundamentally solving the outer flow problem of water in the water tank, must block air and enter water tank.Following inlet and outlet pipe lines lower end in the passage that air enters for this reason, if U type sealing sump, when the water emptying in the pipeline, because the left mouth of a river of this sump is lower than the right mouth of a river, right sump volume of while is generally greater than left sump, so the water in the U type sealing sump is deposited in the sump the actual water valve that plays a part, the air that enters water tank is thoroughly blocked, and the water in the water tank also just can't flow out.When actual emptying, because the gravity of water is bigger, can be with water section or all sucking-offs in the U type sealing sump, this does not influence due effect, because of the air in managing enters water tank, small part water is flowed out, mend full with inhaling empty water in the U type sealing sump, and then play the effect of water valve, reach the purpose that the blocking-up air enters.
During hot water in need use water tank, the switch opens that will control water tank air enters because the air of water tank enters, adds the gravity of water, water can nature pass through last access way and have no to stop through U type sealing sump, pass in and out water channel down and enter the use pipeline.Because the first emptying of ducted water, therefore coming out promptly is hot water.Excessive as the power of letting out under water that flows out, certainly lead to and let out suction down greatly, the activity shutoff in this moment air inlet storehouse may be picked up, and the part air enters pipeline, lets out suction under having slowed down, and then has solved water tank because of the flat difficult problem of the excessive quilt suction of the following power of letting out of water.As the water that stops in the water tank flows out, and only needs the switch that control water tank air enter cuts out get final product, enters owing to stopping air in the water tank, water is carved slightly and promptly can be stopped to flow out, use water valve need continue open as needing ducted hot water emptying this moment, closes after emptying finishes.Be using water wisely, when using hot water to finish, will control the switch that the water tank air enters in advance and close.As not needing emptying, will use valve to close and get final product.
The beneficial effects of the utility model are: this automatic emptying device can realize very easily that it is exactly the function of hot water that the full emptying of pipeline, goes out, and simple to operate, convenient and practical, simple in structure, can fundamentally solve the difficult problem of solar energy pipe insulation in winter.
