Abstract
The utility model relates to a pneumatic emptying valve. An inlet pipe and an outlet pipe are respectively communicated with the water tank of the solar water heater; the inlet pipe and the outlet pipe are communicated with each other under the pipe; the outlet pipe is connected with an air compressor; a non-return outlet valve is arranged on the upper part of the outlet pipe; the optimal inner diameter of the inlet pipe is 5-7mm. In emptying operation, the air compressor forces the retained water in the outlet pipe and the inlet pipe into the water tank of the water heater through the compressed air, which can stably realize the emptying function.
Description
Affiliated technical field
The utility model relates to the device of occluded water in a kind of drain-solar water heater water inlet pipe and water outlet pipe.
Background technology
At present, be the occluded water in the drain-solar water heater water inlet pipe and water outlet pipe, known method is, above water inlet pipe and water outlet pipe, communicate with water inlet pipe and water outlet pipe with a check valve, outside air can enter in the water inlet pipe and water outlet pipe by check valve, and the water in the water inlet pipe and water outlet pipe can not enter in the air by check valve, magnetic valve or motor cut off being communicated with of water inlet pipe and water outlet pipe and solar water heater water tank during emptying, again the drainage switch below the water inlet pipe and water outlet pipe is opened, occluded water promptly under the effect of gravity to dirty.But the magnetic valve of its use or motor are outdoor owing to being in, and usually be damaged by frost in the winter time, and the water in the pipe is fallen the waste that has also caused this part water in gravity extension.
Summary of the invention
In order to overcome that existing exhaust-valve usually is damaged by frost in the winter time and the water let-down in the pipe to be got off to cause the deficiency of water waste, the utility model provides a kind of air pressure exhaust-valve, this air pressure exhaust-valve can not only be realized air emptying function easily, nor can be damaged by frost and cause the waste of water.
The technical scheme that its technical problem that solves the utility model adopts is: have a water inlet pipe and an outlet pipe to communicate with the solar water heater inner water tank respectively, water inlet pipe communicates below their pipeline with outlet pipe, outlet pipe links to each other with an air compressing mechanism, above outlet pipe, be provided with one and go out water one-way valve, water in the water tank can enter outlet pipe by going out water one-way valve, and the water in the outlet pipe can not enter in the water tank by going out water one-way valve, for making the water in the inner water tank not flow back in the water inlet pipe more reliably when the emptying, above water inlet pipe, be provided with and prevent that when emptying aqueous reflux in the water tank from going into the water inlet check valve of water inlet pipe, the best internal diameter of water inlet pipe is 5 to 7 millimeters, the best mode that air compressing mechanism is connected with outlet pipe is, have a wireway one end to connect air compressing mechanism, its other end and outlet pipe are connected near the water tank.When emptying, close water inlet switch and effluent switch, air compressing mechanism is pressed into air in the outlet pipe, pressure increases in the outlet pipe, the water outlet closed check valve that causes the outlet pipe top, because atmospheric density is less than water, air will arrive the top of outlet pipe, air is pressed into the occluded water in the outlet pipe in the water tank by water inlet pipe from top to bottom, when the compressed air in the outlet pipe arrives outlet pipe and water inlet pipe connecting place, air compressing mechanism continues to be pressed into air in outlet pipe, the compressed air in the outlet pipe was equivalent to source of the gas and constantly poured in the water inlet pipe this moment, and the occluded water in the water inlet pipe poured in the water tank, when air compressing mechanism stops to inflate, the hydraulic pressure in air pressure and water tank balances each other air in water inlet pipe and the outlet pipe in the water tank with continuing to flow to, and the residual air pressure in water inlet pipe and the outlet pipe also makes the interior water of water tank can not open out water one-way valve and enters in the outlet pipe.
The beneficial effects of the utility model are, the water in water inlet pipe and the outlet pipe is pressed in the water heater inner water tank with compressed air, have both stably realized air emptying function, also can not cause the waste of water.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure principle chart of the present utility model.
1. air compressing mechanism among the figure, 2. outlet pipe, 3. water inlet pipe, 4. wireway 5. goes out water one-way valve, 6. water inlet check valve, 7. water inlet switch, 8. effluent switch, 9. inner water tank, 10. exhaust outlet.
The specific embodiment
In the embodiment shown in fig. 1, water inlet pipe (3) and outlet pipe (2) communicate with solar water heater inner water tank (9) respectively, water inlet pipe (3) communicates below pipeline with outlet pipe (2), outlet pipe (2) links to each other with air compressing mechanism (1), be provided with one in the top of outlet pipe (2) and go out water one-way valve (5), be provided with in the top of water inlet pipe (3) and prevent that water in the inner water tank (9) from flowing into the water inlet check valve (6) in the water inlet pipe (3), wireway (4) one end connects air compressing mechanism (1), its other end and outlet pipe (2) are connected near the inner water tank (9), and the internal diameter of water inlet pipe (3) is 6 millimeters in this embodiment.
Claims (4)
1. air pressure exhaust-valve, there are a water inlet pipe and an outlet pipe to communicate with the solar water heater inner water tank respectively, it is characterized in that: water inlet pipe communicates below their pipeline with outlet pipe, and outlet pipe links to each other with an air compressing mechanism, is provided with one and goes out water one-way valve above outlet pipe.
2. air pressure exhaust-valve according to claim 1 is characterized in that: be provided with into water check valve above water inlet pipe.
3. air pressure exhaust-valve according to claim 1 is characterized in that: have a wireway one end to connect air compressing mechanism, its other end and outlet pipe are connected near the water tank.
