Abstract
The utility model relates to an overflow preventive valve for a water storage tank of a solar water heater, which is connected with an overflow opening of the water storage tank and mainly consists of a water container and a hollow floating ball located in the water container. A connector which is connected with the overflow opening is arranged on the lower portion of the water container, an air outlet tube is arranged at the top of the water container, a circular bead is disposed on the upper portion of the inner wall of the water container, a pressure release valve is further arranged on the water container, and a sealing gasket is disposed on a guiding tube of the hollow floating ball. The circular bead automatically clings to the sealing gasket by the aid of buoyancy of water, the water is sealed and does not overflow, and after the pressure release valve releases pressure, a sealed state is recovered. When in a waterless state, airflow in the water storage tank can flow along the overflow opening of the water storage tank, and reaches the air outlet tube of the water container via a gap to lead to the atmosphere. The overflow preventive valve for the water storage tank of the solar water heater has an overflow prevention function and a ventilation function, is simple in structure, and is reliable and practical.
Description
Technical field
The utility model relates to solar water heater, particularly the solar water heater storage water tank anti-spill valve.
Background technique
Because the solar water appliance has remarkable advantages such as energy-conservation environmental protection again, therefore generally approved by society, all obtained to apply in the vast town and country of China.Solar water heater mainly is made up of parts such as heat-collecting devcie, water storage box and corresponding inlet and outlet pipe lines.Be equipped with (overflow) mouth of giving vent to anger on the general water storage box, one of its effect is to make water storage box and atmosphere, keeps the balance of water storage box and ambient pressure; Two of effect is that water can overflow from flow-off when the overfill of intaking to water storage box.The user of solar water heater almost will open water supply valve every day to the water storage box moisturizing; But often also can be because of being busy with one's work or other is former thereby forget the pass valve; In this case, a large amount of water drop down from flow-off, not only waste water resource but also bring the trouble of site clearing to people.For this reason, also take in the industry to connect reflow pipe, or way such as solenoid electric valve is installed solves existing problem at flow-off.But the former fails fundamentally to change the status quo, and latter's structure is complicated, must repair maintenance by the professional workforce, also defectiveness.
Summary of the invention
The solar water heater storage water tank anti-spill valve that the utility model proposes, purpose are to control the overflow of solar water heater storage water tank through designing a kind of valve body of simple structure with realization, and have both the ventilatory function of water storage box again.
The technical solution of the utility model
The utility model is connected with the flow-off of solar water heater storage water tank, mainly is made up of water container and the hollow ball float that is positioned at water container.The bottom of described water container is provided with the interface that links to each other with flow-off, and the top of water container is provided with steam outlet pipe, and the upper part of water container inwall and the joint of steam outlet pipe are provided with shoulder.The top of described hollow ball float is provided with guide pipe, and the guide pipe outer wall at position is provided with and the vertical vertical sealing gasket of guide pipe under the guide pipe.
The further technical solution of the utility model:
The guide pipe of said hollow ball float is positioned at the steam outlet pipe of water container.
Said water container is spherical, and top is provided with Decompression valves.
The sphere at position is to be provided with protruding roughened surface under the said hollow ball float.
The beneficial effect of the utility model:
The utility model is according to buoyancy of water, automatically water body sealed and not excessive; Under the state of anhydrous no buoyancy; The hollow ball float falls; Its surface is provided with between protruding roughened surface and the water container inwall and forms the space, and the air-flow in the solar water heater storage water tank can be along the water storage box flow-off, lead to atmosphere through interface, space to water container steam outlet pipe.The utility model has both two kinds of functions of solar water heater storage water tank anti-overflow and ventilation, and simple in structure, reliable and practical.
Description of drawings
Accompanying drawing 1 is in the structural representation of anti-overflow state for the utility model
Accompanying drawing 2 is in the structural representation of aeration status for the utility model.
Embodiment
Like Fig. 1, shown in 2,
The utility model mainly is made up of water container 1 and hollow ball float 2.The bottom of described water container is provided with the interface 11 that links to each other with solar water heater storage water tank flow-off (not shown); The top of water container is provided with steam outlet pipe 12; The upper part of water container inwall and the joint of steam outlet pipe are provided with shoulder 13, and top is provided with Decompression valves 4.The top of described hollow ball float is provided with guide pipe 21, and the guide pipe outer wall at position is provided with and the vertical vertical sealing gasket 22 of guide pipe under the guide pipe, and the sphere at position is provided with protruding 23 under the hollow ball float.Visible by Fig. 1; Interface 11 pours in the water body 3 that comes from water storage box and constantly rises from the bottom in the water container 1; Hollow ball float 2 is at the buoyancy function float downward, and guide pipe also rises along the water container steam outlet pipe, the sealing gasket 22 of hollow ball float just with the sealing that fits of the shoulder 13 of water container upper inside wall; Water body then must not be excessive from the water container air outlet, reaches solar water heater storage water tank anti-overflow purpose.The water body of solar water heater storage water tank heats up after heat exchange, and water storage box air-tight state downforce will increase, and when pressure arrived safety value, the Decompression valves on water container top carried out pressure release, and Decompression valves returns back to former sealing state after the pressure release.Visible by Fig. 2, water container is in anhydrous state, and the hollow ball float falls, and the gas in the solar water heater storage water tank gets into from interface 11, through rising on the space between water container inwall and the hollow ball float, is expelled to atmosphere from the water container steam outlet pipe.
To sum up, the utility model can reach the goal of the invention of expection.
