The utility model discloses a specific pipeline evacuation valves is formed to non -pressure normally -closed solenoid valves and normally open solenoid valve, and hot water is emitted smoothly to the air in the pipeline after the air bleeding valve is discharged under the oppression of rivers, and the evacuation is effectual, but also the water economy resource.
Description
Technical field
The utility model relates to a kind of solar energy water heater pipe emptying system.
Background technology
At present, the tube emptying technology of solar water heater is immature, and after using for a long time because of exhaust-valve, exhaust-valve inside has incrustation scale, and plug the ball valve of exhaust-valve inside, motor easily burns out, and maintenance rate is high; Also have a kind of exhaust-valve to be the exhaust-valve being with magnetic sheet, be also use driven by motor Spool rotating, service life is short; Exhaust-valve is all stealthily bled off through a discharging valve by the ponding in pipe, to reach the object of tube emptying, in fact wastes water resource; The emptying effect of general exhaust-valve is bad, and hot water is out desultory from water pipe, and impact uses; If but not filling emptying system, the cold water hoarded in pipeline needs to bleed off the rear hot water just can used in solar water heater, waste water resource before use.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides that a kind of structure is simple, the solar energy water heater pipe emptying system of economize energy.
The purpose of this utility model is achieved through the following technical solutions: a kind of solar energy water heater pipe emptying system, comprise solar water heater, solar water heater is connected with automatic water-supply apparatus, the outlet pipe of solar water heater is connected with exhaust-valve group, exhaust-valve group comprises normally closed solenoid valve with no pressure and the first normally open solenoid valve, the water inlet of normally closed solenoid valve with no pressure communicates with the outlet pipe of solar water heater, the delivery port of normally closed solenoid valve with no pressure is connected with hot-water line, the gas outlet of the first normally open solenoid valve is also connected with hot-water line, hot-water line is connected with blast pipe, blast pipe is provided with air bleeding valve, the air inlet of the first normally open solenoid valve exposes.
Further improvement of the utility model is: automatic water-supply apparatus is connected with upper hose, and upper hose is provided with the second normally open solenoid valve.
Further improvement of the utility model is: upper hose is provided with water meter, and upper hose communicates with the top of water main.
The utility model compared with prior art has the following advantages: the utility model adopts normally closed solenoid valve with no pressure and normally open solenoid valve to form specific exhaust-valve group, air in pipeline releases hot water smoothly under the compressing of current after air bleeding valve is discharged, emptying effective, but also saving water resource.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-solar water heater, 2-automatic water-supply apparatus, 3-normally closed solenoid valve with no pressure, 4-first normally open solenoid valve, 5-hot-water line, 6-blast pipe, 7-air bleeding valve, 8-upper hose, 9-second normally open solenoid valve, 10-water meter, 11-water main.
detailed description of the invention:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows the detailed description of the invention of a kind of solar energy water heater pipe emptying system of the utility model, comprise solar water heater 1, solar water heater 1 is connected with automatic water-supply apparatus 2, the outlet pipe of solar water heater 1 is connected with exhaust-valve group, exhaust-valve group comprises normally closed solenoid valve 3 with no pressure and the first normally open solenoid valve 4, the water inlet of normally closed solenoid valve 3 with no pressure communicates with the outlet pipe of solar water heater 1, the delivery port of normally closed solenoid valve 3 with no pressure is connected with hot-water line 5, the gas outlet of the first normally open solenoid valve 4 is also connected with hot-water line 5, hot-water line 5 is connected with blast pipe 6, blast pipe 6 is provided with air bleeding valve 7, the water inlet of the first normally open solenoid valve 4 exposes, automatic water-supply apparatus 2 is connected with upper hose 8, and upper hose 8 is provided with the second normally open solenoid valve 9, upper hose 8 is provided with water meter 10, and upper hose 8 communicates with the top of water main 11, cost-saving.
After power supply opening, normally closed solenoid valve 3 with no pressure is opened, hot water in solar water heater flows to hot-water line, first normally open solenoid valve 4 cuts out simultaneously, and the air in hot-water line 5 is forced into blast pipe 6, is discharged by air bleeding valve 7, hot water will flow out continuously, meanwhile, the second normally open solenoid valve 9 cuts out, and automatic water-supply apparatus 2 stops upper water; After power-off, normally closed solenoid valve 3 with no pressure is closed, stop hot-water supply, normally open solenoid valve 4, second normally open solenoid valve 9 is opened simultaneously, air enters hot water pipeline through the first normally open solenoid valve 4, in hot water pipeline, hot water is used up, and hot water pipeline achieves emptying, and in water supply pipe, automatic water-supply apparatus 2 starts upper water.
The utility model adopts normally closed solenoid valve with no pressure and normally open solenoid valve to form specific exhaust-valve group, and the air in pipeline releases hot water smoothly under the compressing of current after air bleeding valve is discharged, emptying effective, but also saving water resource.
