Abstract
An automatic cut-off unit of solar water heater can play its role when water is full. It is composed of power pipe, flexible pipe, cavity, pneuamtic rubber, membrane, force collecting plate, force transfer rod, and water supply valve with ceramic spool. When overflow water flows via overflow tube in said power pipe, it generates water pressure to cut-off said water supply valve. Its advantages are high reliability, no generation of water scale, and long service life.
Description
Technical field
The present invention relates to the full self closing device of a kind of solar water heater water.
Background technology
Pressure-bearing type solar water heater does not use two water pipes, a water-intake pipe, an overflow pipe.Water-intake pipe is used on the solar water heater running water and hot water down, and overflow pipe is at present only for observing the full usefulness of water when going up water.Water-intake pipe and overflow pipe upper end are coupled to the solar water heater relevant position, and the lower end is indoor through the open air introducing.Termination is mixed water valve under the water-intake pipe, and the overflow pipe lower end is fixed on the position of being convenient to observe current.When the solar water heater filling up water, overflow water just releases from the overflow pipe lower end, and the manual-lock water supply valve is finished water in view of the above.For water is closed completely automatically, people or with ball-cock assembly or use magnetic valve, the problem that their exist is: device must be immersed in the hot water, and incrustation scale makes them very fast malfunctioning.The also useful way that installs secondary water tank additional, but its not only cost is high but also antifreeze difficulty.
Summary of the invention
The purpose of this invention is to provide the full self closing device of a kind of solar water heater water, it is not immersed in the hot water, so be difficult for forming incrustation scale, its not electricity consumption also need not secondary water tank, and is indoor owing to being contained in, and do not have antifreeze problem.
The present invention is achieved in that power pipe of design, and it is made up of outer tube and the inner sleeve that is inserted in wherein.Form certain space between outer tube and the inner sleeve, outer sleeve upper is higher than inner sleeve upper end certain-length and a baffle plate is arranged in this length, and the outer tube lower end is shorter than inner sleeve lower end certain-length and links together with the inner sleeve sealing.One through hole is arranged on the outer tube, and it is positioned at sealing junction top near the sealing junction, and correspondence position has an aperture on the inner sleeve.A flexible pipe is connected through hole with a cavity, cavity simultaneously has the pneumatic rubber film that combines with the cavity sealing, and its appearance has a circular force collecting plate, and there is a transmission rod at its center.The overflow pipe lower end is inserted within the outer sleeve upper.When on the rotary ceramic core water supply valve spiral arm during water (mix water valve and close this moment), the transmission rod top contacts with spiral arm, and running water is through ceramic core water supply valve, water-intake pipe water on solar water heater.Water completely after, overflow water is let out under overflow pipe, flows in the power pipe.Because the effect of baffle plate, overflow water at first flows in the space between inner sleeve and the outer tube, the space is full of formation hydraulic pressure by overflow water rapidly, air in via through holes, the hose compression cavity, make the effect of being under pressure of pneumatic rubber film, promote force collecting plate, make the reverse rotation of ceramic core water supply valve spiral arm close, stop to go up water by transmission rod.Overflow water is let out until having let out under just flowing into when rising to the height of inner sleeve upper end and continuing in the inner sleeve.After overflow water in the overflow pipe had been let out, the overflow water in the space was let out light gradually from the aperture on the inner sleeve, and hydraulic pressure disappears.Go up water later on and repeat said process.
Owing to adopt such scheme, there is water to flow through in the very short time that the power pipe is only let out under overflow water, so be difficult for forming incrustation scale.This device is installed on indoor, does not have antifreeze problem.
The present invention is further described below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing is a structure cut-away view of the present invention.
1 outer tube, 2 inner sleeves, 3 spaces, 4 outer sleeve uppers, 5 inner sleeves upper end, 6 baffle plates, 7 outer tube lower ends, 8 inner sleeve lower ends, 9 through holes, 10 apertures, 11 flexible pipes, 12 cavitys, 13 pneumatic rubber films, 14 transmission rods, 15 force collecting plates, 16 ceramic core water supply valves, 17 spiral arms, 18 overflow pipes, 19 mix water valve, 20 running water inlet, 21 water-intake pipes, 22 power pipes in the accompanying drawing.
The specific embodiment
In the accompanying drawing, power pipe 22 is made up of outer tube 1 and the inner sleeve 2 that is inserted in wherein, forms space 3 between outer tube 1 and the inner sleeve 2, and outer sleeve upper 4 is higher than inner sleeve upper end 5 certain-lengths, so that insert in the outer sleeve upper 4 overflow pipe 18 lower ends.Outer tube lower end 7 links with inner sleeve 2 sealings, and a through hole 9 is arranged on the outer tube 1, and correspondence position has an aperture 10 on the inner sleeve 2.Flexible pipe 11 is connected through hole 9 with cavity 12, cavity 12 one sides are the pneumatic rubber films 13 that combine with its sealing, and its appearance has a circular force collecting plate 15, and there is a transmission rod 14 at its center.
During water (mix water valve 19 and close this moment), transmission rod 14 tops contact with spiral arm 17 on the spiral arm 17 on being rotated counterclockwise ceramic core water supply valve 16.Running water is through running water inlet 20, ceramic core water supply valve 16, water-intake pipe 21 water on solar water heater.Water completely after, overflow water is let out for 18 times through overflow pipe, flows in the power pipe 22.Because the effect of baffle plate 6, overflow water at first flows in the space 3, space 3 is full of formation hydraulic pressure by overflow water rapidly, air in via through holes 9, flexible pipe 11 compression chambers 12, make pneumatic rubber film 13 effect of being under pressure, promote force collecting plate 15, make spiral arm 17 turn clockwise by transmission rod 14 and close, stop to go up water.Overflow water is let out until having let out under just flowing into when rising to the height of inner sleeve upper end 5 and continuing in the inner sleeve 2.After overflow water in the overflow pipe 18 had been let out, the overflow water in the space 3 was let out light gradually from the aperture 10 on the inner sleeve 2, and hydraulic pressure disappears.Go up water later on and repeat said process.
When the overflow water in the space 3 reached the height of inner sleeve upper end 5, it is constant that hydraulic pressure will reach setting value, has nothing to do with the size in space 3 and the height of overflow pipe 18.Cavity 12, pneumatic rubber film 13, transmission rod 14, force collecting plate 15, ceramic core water supply valve 16, spiral arm 17, the mixed water valve 19 actual one that are made for.
