Abstract
The invention relates to a backflow-preventing water feeding indicating device of a solar water heater. The backflow-preventing water feeding indicating device is composed of a transparent connecting pipe two ends of which are provided with threads, a small backflow preventing ball and a check ring, wherein the upper end of the connecting pipe is used for placing the check ring, and the periphery of the check ring is provided with bulges for preventing the small ball from overflowing out; the diameter of the inner wall of the lower end of the connecting pipe is reduced, the small backflow preventing ball can be stayed on the lower end of the connecting pipe, the small ball floats in an upper-down manner under the water flow impulsion when water enters, and the indication action is generated; and when the water pressure is overlow, the small ball falls in the inner diameter shrinking position of the lower end of the connecting pie due to gravity, the small ball and the shrinking position are in line contact and are closely closed so as to prevent the water from backflow. The backflow-preventing water feeding indicating device provided by the invention has the advantages that the structure is simple, the installation is convenient, and the effect is very ideal after in-service use.
Description
Technical field
The present invention relates to water indicating device on a kind of solar water heater anti-return.
Background technology
Along with extensive use and the environmental consciousness enhancing of heliotechnics, solar water heater is used widely.In the solar water heater used at present, the overwhelming majority is all same pipeline for upper and lower hydromining, relies on Special three-way valve to control Inlet and outlet water.But when in use hydraulic pressure is low, hot water very easily refluxes, cause hot water loss and economic loss.Those skilled in the art has developed some back-flow preventers, but exists some disadvantages, such as, adopt some flexible pieces easily aging, the shortcomings such as complex structure easy break-down
.
Summary of the invention
Purpose of the present invention is exactly for the defect existed in prior art, at water feeding of heater, a back-flow preventer partly is set, thereby has solved the problem of hot water return.
To achieve these goals, the present invention has adopted following technical proposals:
Water indicating device on the solar water heater anti-return, it is comprised of the threaded transparent connecting tube in two, anti-return bead and back-up ring.Back-up ring can be placed in the connecting tube upper end, and the projection that prevents that bead from overflowing is arranged on the back-up ring circumference.The lower end inner diameter of connecting tube reduces, above the bead of anti-return can rest on.The connecting tube at right angle setting that must upper end makes progress during installation.
By technique scheme, can be found out, on anti-return, the water indicating device is installed on the water inlet pipe place, and water inlet pipe is through after this device, the upper water controller such as connecting tee.Can effectively prevent hot water return, when upper water, bead fluctuates under water impact, plays indicative function.When hydraulic pressure is too low, bead is because Action of Gravity Field drops to inside diameter contraction place, connecting tube lower end, and bead takes line to contact with contraction place, thereby the anti-sealing of tight closure refluxes.It is simple in structure, easy for installation, through reality, uses its effect ideal.
In order to describe in further detail the present invention, below in conjunction with drawings and Examples, technique scheme is described further.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is top views of 2 in accompanying drawing 1;
In figure:
The 1-connecting tube; The 2-bead; The 3-back-up ring.
The specific embodiment
As shown in the figure, during installation, the necessary at right angle setting of connecting tube 1, have an end of back-up ring 2 upwards, and it is downward that inside diameter shrinks an end of placing bead 3.Running water upper water controller such as connecting tee again after tube connector.
When opening upper taps, during this device of running water process, when hydraulic pressure is sufficient, bead is rushed to open, and running water, through this device, enters solar energy.Because upper end has with protruding back-up ring, bead can not be washed into upper end and stop up upper water.In upper water process, bead fluctuates, and plays indicative function.
When hydraulic pressure is not enough, bead makes closedown of pipeline because Action of Gravity Field drops to connecting tube lower end diameter contraction place naturally, thereby anti-sealing refluxes.
Claims (3)
1. water indicating device on the solar water heater anti-return, is characterized in that it is comprised of the threaded transparent connecting tube in two, back-up ring, bead.
2. on the solar water heater anti-return that claim 1 is stated, the water indicating device is characterized in that there is the back-up ring that prevents that bead from overflowing the connecting tube upper end.
3. on the solar water heater anti-return that claim 1 is stated, the water indicating device is characterized in that the bead that the connecting tube lower end has anti-sealing to reflux.
