Abstract
The utility model discloses a manual pneumatic emptying valve for a solar pipeline, and relates to the technical field of emptying of solar pipelines. The manual pneumatic emptying valve for the solar pipeline comprises a water inlet pipeline, a power chamber, a water outlet pipeline and an air inlet pipeline, wherein a water inlet of the water inlet pipeline is formed in a solar heat-preservation container, and is provided with a sealing plug which is connected with a piston through a connecting rod; the piston is arranged in the power chamber which is connected with an upper air channel and a lower air channel; the upper and lower air chambers are connected with an air pump through a reversing valve respectively; one end of the water outlet pipeline is away from a water outlet, and two branches are arranged at the end, one branch is communicated with the water inlet pipeline, and the other branch is connected with the air inlet pipeline; and a check valve is arranged at an air inlet of the air inlet pipeline. Water accumulated in the solar pipeline can be effectively emptied, and can be prevented from being frozen, and the normal use of solar energy in winter can be ensured.
Description
Technical field
The utility model relates to the solar tube emptying technical field, is specially a kind of hand-driven pressure solar tube emptying valve.
Background technique
Existing solar tube emptying technology mostly is electric atmospheric relief valve, and its shortcoming is that working life is short, generally only has 2-3, and maintenance rate is high, almost can reach more than 90%.Existing Manual drain valve can only be connected with warming solar energy bucket water outlet, and is the mechanical type manual operation, only climbs to roof or roof during operation and settles the position of solar energy to implement, and operates extremely inconvenient.
Summary of the invention
The utility model is for above deficiency, a kind of hand-driven pressure solar tube emptying valve is provided, and cubicle switch operation (convenience) can the interior ponding of effective emptying solar pipe, prevent that the pipeline internal water accumulation from freezing, guarantee that cold season in winter, solar energy can normally use.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of hand-driven pressure solar tube emptying valve, include the water intake pipeline, engine room, the water outlet pipeline, air inlet duct, the water intake of described water intake pipeline is arranged in the warming solar energy bucket, described water intake is provided with sealing plug, described sealing plug links to each other with piston by connecting rod, described piston is arranged in the engine room, described engine room is connected with gas circuit and lower gas circuit, described upper gas circuit links to each other with air pump by selector valve respectively with lower gas circuit, described water outlet pipeline is provided with two branches away from an end of water outlet, one communicates with the water intake pipeline, another is connected with air inlet duct, and the suction port place of described air inlet duct is provided with one-way valve.
Described one-way valve is set to the unidirectional lobe formula switch of opening that cooperates the natural rubber breast film of different azimuth punching to make with circular punching rubber pad.
The beneficial effects of the utility model are: utilize manual pressure to impel piston movement, the drivening rod lifting, the water outlet of control solar pipe, utilize the ponding in the barometric pressure emptying pipe when closing, ponding in can effective emptying solar pipe, prevent that the pipeline internal water accumulation from freezing, guarantee that cold season in winter, solar energy can normally use.
Description of drawings
It is structural representation of the present utility model shown in the accompanying drawing.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
As shown be a specific embodiment of the present utility model, the water intake 11 of described water intake pipeline 1 is arranged in the warming solar energy bucket 12, described water intake 11 is provided with sealing plug 13, described sealing plug 13 links to each other with piston 21 by connecting rod 14, described piston 21 is arranged in the engine room 2, described engine room 2 is connected with gas circuit 22 and lower gas circuit 23, described upper gas circuit 22 links to each other with air pump 6 by selector valve 5 respectively with lower gas circuit 23, described water outlet pipeline 3 is provided with two branches away from an end of water outlet 31, one communicates with water intake pipeline 1, another is connected with air inlet duct 4, suction port 41 places of described air inlet duct 4 are provided with one-way valve 42, and described one-way valve 42 is set to the unidirectional lobe formula switch of opening that cooperates the natural rubber breast film of different azimuth punching to make with circular punching rubber pad.
When we use the water of solar energy, selector valve 5 of the present utility model can be communicated with lower gas circuit 23, at this moment, gas in the air pump 6 enters engine room 2 by lower gas circuit 23 and forms air pressure, piston 21 in the air pressure propulsion power cabin 2 moves upward, piston 21 drives sealing plug 13 by pull bar 14 and moves upward, water intake 11 just has been opened, water in the warming solar energy bucket 12 just can flow out by water intake 11, water flows out by water outlet 31, at this moment, be in closed condition under the Water Pressure of one-way valve 42 in the warming solar energy bucket.When we do not use water in the solar energy, selector valve 5 of the present utility model can be communicated with upper gas circuit 22, at this moment, gas in the air pump 6 enters engine room 2 by upper gas circuit 22 and forms air pressure, piston 21 in the air pressure propulsion power cabin 2 moves downward, piston 21 drives sealing plug 13 by pull bar 14 and moves downward, water intake 11 has just been blocked by sealing plug 13, water just stops to having outflowed, at this moment, one-way valve 42 will be opened automatically, and air just can enter water outlet pipeline 3 by one-way valve 42, impel water outlet pipeline 3 interior remaining water to flow out from water outlet 31.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
