Abstract
The utility model relates to a pipeline draining mechanism of an unpressurized integrative solar water heater, which comprises a water tank, an overflow pipe and a water inlet/outlet pipe; the improvements on the pipe draining mechanism lie in that a small water tank is arranged at the top end of the water tank; a water inlet/out inner pipe vertically extending the bottom of the water tank is arranged in the small water tank; the upper part of the water inlet/outlet inner pipe is connected with a water inlet/outlet pipe; a draining pipe is connected with the top end of the water inlet/outlet inner pipe; a solenoid valve is connected with the tail end of the draining pipe; and the solenoid valve is connected with a delay switch. The utility model has the advantages that when in use, the draining pipe is closed to fully fill the water inlet/outlet pipe with water, and the siphonage is adopted to discharge the water; furthermore, after the solar water heater is used, the valve of the draining pipe is opened, the water in the water inlet/outlet pipe is drained by utilizing the communicating vessels principle, so as to prevent the pipeline from being damaged and cracked due to freezing. The utility model has the advantages of simple structure, low cost and low maintenance rate.
Description
Technical field
The utility model relates to a kind of solar water heater, particularly a kind of non-pressure-bearing all-in-one solar energy water heater pipe emptying mechanism.
Background technology
Solar water heater is and one of gas heater, electric heater three big water heaters mutually arranged side by side.It is compared with gas heater with electric heater, the solar water appliance has environmental protection, non-environmental-pollution, characteristics such as long service life are widely used, its utilization is arranged on outdoor heat collector and absorbs sunshine, cold water in the storage tank is heated to high-temperature from low temperature, uses to satisfy the hot water of people in life, production.Solar water heater is arranged on daylighting roof preferably usually, and it uses for the user by the pipeline access is indoor.Because inlet and outlet pipe lines must be from outdoor access water heater, the easy freezing pipeline of winter or severe cold area, how solving its antifreeze problem becomes a difficult problem.The existing market upper pipeline adopts the ribbon heater antifreeze more, and it exists shortcoming to be: not only power consumption is big, easy break-down, and have potential safety hazard.
The utility model content
The technical problems to be solved in the utility model provides a kind of emptying mechanism that prevents the bursting by freezing of non-pressure-bearing all-in-one solar energy water heater pipe.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of non-pressure-bearing all-in-one solar energy water heater pipe emptying mechanism, comprise water tank, overflow pipe, water inlet pipe and water outlet pipe, its innovative point is: described water tank top is provided with little water tank, be provided with pipe in the Inlet and outlet water that vertically stretches into water tank bottom in it, the top of pipe is connected with water inlet pipe and water outlet pipe in the described Inlet and outlet water, and the top is connected to evacuated tube, described evacuated tube end is connected with magnetic valve, and described magnetic valve is connected with delay switch.
Further, be serially connected with standby ball valve on the evacuated tube at described magnetic valve rear, and on evacuated tube, be provided with and magnetic valve and standby ball valve release valve ball in parallel.
Advantage of the present utility model is: during use, evacuated tube is closed, and will be full of water in the water inlet pipe and water outlet pipe, utilizes the siphonage use that discharges water.Open the valve of evacuated tube after being used to complete, utilize law of connected vessels that the water in the water inlet pipe and water outlet pipe is discharged, prevent freezing, the bursting by freezing of pipeline.It has advantage simple in structure, that cost is low and maintenance rate is low.
Description of drawings
Accompanying drawing is the fundamental diagram of the non-pressure-bearing all-in-one of the utility model solar energy water heater pipe emptying mechanism.
The specific embodiment
As shown in drawings, comprise pipe 7, water inlet pipe and water outlet pipe 10, evacuated tube 4, magnetic valve 2, standby ball valve 1, release valve ball 3 in water tank 8, exhaust outlet 5, overflow pipe 9, little water tank 6, the Inlet and outlet water.
During use, by water on the 10 pairs of water tanks 8 of water inlet pipe and water outlet pipe that are connected with tap water pipe line, water tank water is full when seeing the terminal water outlet of overflow pipe 9, stops to go up water.Evacuated tube magnetic valve 2 is in closed condition at this moment, be full of water in the water inlet pipe and water outlet pipe 10, utilize siphonage water can be emitted during water, press delay switch after using up then, this delay switch control magnetic valve 2 is opened, utilize law of connected vessels with water emptying in the water inlet pipe and water outlet pipe 10, after the regular hour, delay switch control magnetic valve 2 cuts out.By the water inlet pipe and water outlet pipe 10 that with running water system be connected advance running water 8-10 second after during water next time, makes to be full of water in the water inlet pipe and water outlet pipe 10, can emit the interior hot water of water tank 8, with after press delay switch, carry out emptying again.
In order to prevent that delay switch or magnetic valve 2 from damaging influence and using or emptyings, be serially connected with standby ball valve 1 on the evacuated tube 4 at described magnetic valve 2 rears, and on evacuated tube 4, be provided with the release valve ball 3 in parallel with magnetic valve 2 and standby ball valve 1.When delay switch or magnetic valve 2 damage, the standby ball valve 1 of manual-lock, manually opened release valve ball 3 carries out emptying.
Claims (2)
1. non-pressure-bearing all-in-one solar energy water heater pipe emptying mechanism, comprise water tank, overflow pipe, water inlet pipe and water outlet pipe, it is characterized in that: described water tank top is provided with little water tank, be provided with pipe in the Inlet and outlet water that vertically stretches into water tank bottom in it, the top of pipe is connected with water inlet pipe and water outlet pipe in the described Inlet and outlet water, the top is connected to evacuated tube, and described evacuated tube end is connected with magnetic valve, and described magnetic valve is connected with delay switch.
