Abstract
The invention discloses an automatic overflow preventing switch for a solar water heater, which relates to the technical field of solar water heaters. The automatic overflow preventing switch comprises a floater, a floater force arm, and a combined valve comprising a cavity A and a cavity B which are distributed in a crossed manner. With the structure, compared with the prior art, the automatic overflow preventing switch has the advantages of simple structure, convenience for use, safety, reliability and water saving.
Description
?
Technical field
The present invention relates to technical field of solar water heaters, particularly relate to the anti-overflow switch on a kind of solar water heater.
Background technology
In the daily life, the solar energy that people use because of daytime hydraulic pressure low, the solar energy of the eminence water that do not increase.Wait until the late into the night, could go up water when hydraulic pressure is high.But this time period will have a strong impact on people's normal rest, and the unmanned pipe of filling up water easily takes place, and cause the situation of a large amount of water outflows.Automatic loading water switch of the prior art, a kind of is mechanical type with the direct gauge tap of water level, but little because of its pressure and buoyancy gap, does not thoroughly overcome the above problems; Second kind is electromagnetic type, big, high, the poor stability, impracticable of fault rate of its investment.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of solar water heater simple in structure, esy to use, safe and reliable, the conserve water resource automatic anti-overflow switch.
The present invention includes the float and the float arm of force, it also comprises the combination valve of being made up of the A chamber of cross-shaped distribution and B chamber, and described A chamber comprises A chamber valve, A chamber, and described B chamber comprises B chamber end cap, B chamber valve spring, B chamber valve and B chamber; Described float is connected by the float arm of force with A chamber valve, and the end of the float arm of force is connected with A chamber valve; B chamber valve is connected with B chamber end cap by B chamber valve spring; Described combination valve is set in place the water pipe top end in tank, and the combination valve lower end is connected with the water pipe that is connected with Cold water tap and hot-water valve.
The present invention compared with prior art has advantage simple in structure, esy to use, safe and reliable, water-saving owing to adopt above structure.
Description of drawings
Accompanying drawing is the structural representation of the automatic anti-overflow switch of solar water heater of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated:
Among the figure: 1, float, 2, the float arm of force, 3, support before the arm of force, 4, A chamber valve, 5, the A chamber, 6, B chamber end cap, 7, B chamber valve spring, 8, B chamber valve, 9, water pipe, 10, the B chamber, 11, tank, 12, horizontal plane, 13, Cold water tap, 14, hot-water valve.
As shown in drawings, it comprises the float and the float arm of force, and it also comprises the combination valve of being made up of the A chamber of cross-shaped distribution and B chamber, and the A chamber comprises A chamber valve, A chamber, and the B chamber comprises B chamber end cap, B chamber valve spring, B chamber valve and B chamber; Float is connected by the float arm of force with A chamber valve, and the end of the float arm of force is connected with A chamber valve; B chamber valve is connected with B chamber end cap by B chamber valve spring; Described combination valve is set in place the water pipe top end in tank, and the combination valve lower end is connected with the water pipe that is connected with Cold water tap and hot-water valve.
A chamber and accent are filling pipe end (or water inlets), open Cold water tap when tank is anhydrous, and A chamber valve is opened because of the pressure of ascending water in the A chamber, and B chamber valve cuts out because of the pressure of B chamber valve spring.Cold water enters tank by the A chamber.When water level arrives to a certain degree, float is held up,, A chamber valve cuts out, at this moment the tank topped up with water by the float arm of force.
When water, open hot-water valve, the water in the water pipe flows out, and makes the hypotension in the A chamber arrive the generation negative pressure, and then the atmospheric outside effect lower compression of B chamber valve B chamber valve spring is opened B chamber valve, and the water of tank is flowed out by B chamber, B chamber valve and water pipe.When the water surface of tank is reduced to a certain degree, float descends, and A chamber valve is opened, and the water pressure in the water pipe increases, and the hot-water valve flow strengthens, hot-water supply.
The present invention can be placed directly in the warming solar energy bucket, also can be placed in the tank of doing separately, and the delivery port with bottom of gullet water pipe linker and warming solar energy bucket connects together then.
Above-described embodiment, the present invention specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in technical scheme scope of the present invention and replacing all should be included within protection scope of the present invention.
