Abstract

The utility model relates to an automatic water-supply single pipe type siphon freezing-proof solar water heater. A siphon and a water inlet pipe are mutually formed by the mode of one divided into two through a water inlet pipeline and a siphon pipeline. A water inlet valve and a back valve are arranged for alternatively controlling water entering and discharging. The functions of automatic water supplement, siphon water discharging, freezing prevention of the pipelines, etc. can be realized. Meanwhile, the quantity of the pipelines can be reduced. Thereby, the utility model has the advantages of reduction of construction difficulty and cost, simple utilization and safety.

Description

Automatic water supplement single hose siphon anti-freezing solar water heater

The utility model relates to the hydrocone type anti-freezing solar water heater, especially automatic water supplement single hose siphon anti-freezing solar water heater.

In the north, solar water heater uses very general, but in the winter of cold, the antifreeze problem of the pipeline of solar water heater has become to influence the biggest obstacle of its use.Present solar water heater generally comprises hydrocone type upper and lower conduit, overflow pipe, and what have also is connected to independent upper hose at water tank bottom, and the increasing of pipeline certainly will cause to be exposed to outdoor pipeline area and to increase, and gives the antifreeze difficulty that increased.Simultaneously, the design of multitube road makes the pipeline structure complexity in the inlet chamber, has increased the difficulty of installation, and has increased corresponding cost.

The purpose of this utility model provides a kind of single tube line structure, simple, easy to use, reliable automatic water supplement single hose siphon anti-freezing solar water heater is installed.

For achieving the above object, by the following technical solutions:

A kind of automatic water supplement single hose siphon anti-freezing solar water heater, comprise water tank, siphon pipe, upper and lower conduit and corresponding solar thermal collector, junction at siphon pipe and upper and lower conduit is provided with automatic exhaust steam valve, which is provided with control circuit, it is characterized in that described siphon pipe is made of inlet pipeline and siphon pipeline, both one, inlet pipeline is made of a water intaking valve, the siphon pipeline directly stretches into water tank bottom, and inside is provided with non-return valve; The water intaking valve open top, in have float type piston to control its switching, float type piston is made of piston rod and ball float, the piston rod top is provided with the push jack of an area greater than aforementioned opening, near opening, be provided with the rubber gasket of intermediate openings, it has the ceramic seal pad of intermediate openings, circular ceramic seal gasket, spring, baffle plate down successively, baffle plate hollow, and leave the space between piston rod.

The utility model has adopted the mode of inlet pipeline and siphon pipeline one cleverly, reduced the pipeline quantity of turnover water tank, make its compact conformation, simple, simultaneously, be exposed to water tank outer contain water lines seldom, antifreezely easily add the effect of automatic exhaust steam valve, antifreeze problem is readily solved with emptying siphon pipe function.Utilize the pipeline structure of this one-to-two, Shang Shui, following water management conveniently do not need the overflow inspection, and water tank water is full, and the automatic blocking water intaking valve is safe and reliable, in case the interior device damage of water tank can integral body be taken out the damage device, keep in repair very convenient.This device only needs to make a call to the thick eye of a vacuum tube at water tank upper, puts the silica gel circle, will install the insertion water tank then and get final product, and installs very simple.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

Fig. 1 is the utility model water tank part overall schematic.

Fig. 2 is the structural representation of the utility model water intaking valve and siphon pipe combination.

Automatic water supplement single hose siphon anti-freezing solar water heater, comprise water tank 1, siphon pipe 2, upper and lower conduit 4 and corresponding solar energy heat collector, as shown in Figure 1, omitted solar energy heat collector among the figure, wherein, automatic exhaust steam valve 5 has been installed in the junction of siphon pipe 2 and upper and lower conduit 4, it is straight-through indoor to which is provided with control circuit 6, thereby prevent to freeze as emptying siphon pipe 2 and upper and lower conduit 4, the pipeline that siphon pipe 2 is positioned at water tank 1 outside is coated with insulation material 16 on every side, also is antifreeze usefulness.The structure of siphon pipe 2 is the structure of one-to-two, is made of inlet pipeline and siphon pipeline, and both one are connected with water tank 1 common pall outward.Inlet pipeline is made of a water intaking valve 3, and the siphon pipeline directly stretches into water tank 1 bottom, and inside is provided with non-return valve 7.Water intaking valve 3 enters in the water tank 1 in order to the water of control common pall, as shown in Figure 2, its crown center opening, in have float type piston to control its unlatching, float type piston is made of piston rod 13 and ball float 14, and piston rod 13 tops are provided with an area greater than aforementioned water intaking valve 3 open-topped push jacks 15.Nestle up above-mentioned opening, be provided with the ceramic seal gasket 10 of the rubber gasket 8 of the intermediate openings that seals, the ceramic seal pad 9 of intermediate openings, circular not opening successively and withstand on the spring 11 on the ceramic seal gasket, the baffle plate 12 of support spring 11, baffle plate 12 hollows, piston rod 13 passes baffle plate 12 middle parts, and 12 on baffle plate has activity space.The push jack 15 of piston rod 13 also can withstand on the ceramic seal gasket 10 just.

Using method is as follows:

1. go up water, as shown in Figure 1, being fetched water by upper and lower conduit enters common pall, hydraulic pressure is closed the non-return valve 7 in the siphon pipeline, and water intaking valve 3 top open parts are subjected to the hydraulic pressure effect, promotes ceramic seal gasket 10 downward pressuring spring 11 distortion, this opening is opened, and water enters in the water tank 1 thus.When water in the water tank 1 was full, ball float 14 was subjected to buoyancy piston rod 13 upwards to promote the ceramic seal pad 9 that ceramic seal gasket 10 compresses upside, and opening is closed, and stops into water automatically.

2. use hot water: open indoor Cold water tap, make when the high water column of 3-5m is arranged in the upper and lower conduit 4, close Cold water tap, open hot water valve, when expiring owing to water tank 1 interior water, the opening of water intaking valve 3 is closed, this moment, siphon pipe utilized siphon principle, gushed on the hot water, pushed non-return valve open, flow out along pipeline, in the inlet chamber.During full water, water intaking valve 3 openings are not subjected to spring pressure to cause opening to close to water tank 1.

3. antifreeze: as to utilize automatic exhaust steam valve 5, make siphon pipe 2 enter air, get final product the fast evacuation pipeline, reach antifreeze purpose.

4. automatic water supplement: after water level in the water tank 1 descended, ball float 14 drove piston rods 13 and descends, thereby under the hydraulic pressure effect, the import of water intaking valve 3 is opened, and water is mended in the water tank 1 automatically, and after water was full, ball float 14 rose, and closes water intaking valve 3 automatically, stops to add water.
