Background technology

Present solar water heater, in the time entering cold water, its level control is generally all controlled by people, overflow pipe when people is controlled above Main Basis solar water heater water tank, this access water tank top, overflow pipe one end, the other end is connected in the pond in user family always, in the time that on roof, solar water container overflows, spilling water flows to the pond of user family by overflow pipe, and people see flows out spilling water in overflow pipe, just close inlet valve immediately, water tank stops into water.Because overflow pipe is very long, water in pipe is to be all generally put in pond to flow away in vain, and to someone go seeing, often in an unguarded moment, current lose a lot, and the water level of inner water tank is put less, water tank utilizes rate variance, if put fullly, after water solarization heat, have again more hot water and overflow, waste hot water.Because solar water container internal temperature is high, also has special circumstances that vapour pressure etc. is different from general water tank little other method of employing except topmounter's industry control water level method, control water level although fill ball-cock assembly in some water tanks, but it is all very flimsy resembling this mechanical seal movable part of ball-cock assembly, can not in hot water, use again, once bad terrible upper roof goes maintenance, very trouble is and dangerous, and therefore common people can not select the roof tank with ball float; With electrically operated valve, cistern water level is controlled in addition, it is also pretty troublesome that such water power is used in conjunction product.If can design not electricity consumption of one, without ball-cock assembly, the unfavorable conditions of solar water container is become to favorable factor, solar water container water level is controlled automatically, not only can using water wisely, but also in the busiest moment, needn't on tenterhooksly remove to keep an eye on water tank before can making people go to work in the morning, be also the one liberation to char.

Summary of the invention

The purpose of this utility model is: release a kind of device that roof tank is carried out to automatic control.

The purpose of this utility model is achieved in that it comprises a solar water container, a high level control box is set above solar water container side, in high level control box, top down establish a steam thermal insulation board with end seam, high level control box is divided into left and right two Room by this steam thermal insulation board; The upper wall of left and right two Room respectively has passage, on the wall of upper left, also admittedly inserting the connecting leg of calming the anger, internal diameter very little air pressure transfer tube is connected on the connecting leg top of calming the anger, the high-order bit of air pressure transfer tube is lower than the bleeder pipe by drawing in solar water container, relative aperture its large air pipe is connected in the connecting leg bottom of calming the anger, the high level control box right ventricle connection aqueduct of going to the bottom, aqueduct stretches in solar water container; Bleeder pipe on solar water container and high level control box form two ends of linker, high level control box water level rises and enters air pressure transmission after making the air pressure that produces in air pipe by the connecting rod of calming the anger and pass pipe pressure is passed in the pneumatic valve device in user family, make the airbag aeration in pneumatic valve device produce expansive force, this expansive force promotes low discharge inching valve depression bar, causes normal heat water valve to be closed.It is characterized in that: in high level control box apart from can being also provided with the overflow groove that can absorb thermal expansion water in solar water container outside pneumatic valve device provides the air pipe of operating air pressure.

Air pressure in the complete pressured tracheae of pneumatic valve device promotes like this, and the height that the size of air pressure is just mainly risen in air pipe by waterline and area and compressed gas temperature decide, as too large in pneumatic tube area, the water surface has more steam, the stable delivery of air pressure will be affected, therefore the height of air pipe is must be enough high and leave larger variable value, therefore when one end of linker is high level control box, the other end must be the adjutage higher than solar water container (abbreviation water tank), otherwise can account for larger a part of water space of inner water tank.Admittance water pipe under high level control box right ventricle, aqueduct lower end and water tank communicate, and because of the waterline of calming the anger of air pipe in high level control box will be higher than inner water tank roof, according to the principle of linker, air pipe during to water tank water intake in high level control box is risen by water level and produces pressure, in inner water tank, water inlet (because that section of size of the high water tank of bleeder pipe can be established very longly, therefore guaranteeing that the water in water tank whenever can not overflow from bleeder pipe) will be full of; High level control box inner vapor dividing plate can also deaden a small amount of steam out in aqueduct and air pipe, a small amount of steam will be overflowed from nearer right ventricle's passage, and water can be through end seam circulation below steam dividing plate, do not affect the rising of the waterline of calming the anger, the passage above left chamber guarantees that the left chamber water surface leads to atmosphere.When the rise pressure that produces in air pipe of the waterline of calming the anger makes to be connected in pneumatic valve device that balloon membranes on air bag seat stretches and compressing is fixed in the pressed sheets on depression bar, make low discharge inching valve become and close valve while cutting off the water state from the water inlet state of often opening, in solar water container, entered full water, at this moment waterline will rest on Pneumatic water bit line and slightly go up and can not make water overflow.But pass through solar energy heating, water will expand and volume becomes large, and water level will continue rising, and the water of rising stores entering in the overflow groove of high level control box, so both fully used the water tank volume that discharges water, the spilling water waste producing after can not making again water tank be heated.In the time that user uses hot water, close to open after water outlet pipe valve and just can use with water valve, water level decline while being finished water tank hot water, without air pressure, then opens water outlet pipe valve in air pipe, and low discharge inching valve is because losing pressure and in Chang Kaizhuan, again to water tank water intake.The length of air pipe is peaceful long not short according to situations such as the required pressure of air bag and air temperature variations, in pipe, air pressure should not be very large, therefore its pressure should be applicable to promoting low discharge inching valve, often open fluid valve as small-bore and (should adopt lever and spring when with normally closed fluid valve, pressurized while making the water inlet of fluid valve depression bar, close at ordinary times), in the time using in the lower water pipe of high-rise hydraulic pressure, to be difficult to action according to fluid valve principle, at this moment the low discharge inching valve in pneumatic valve device can change sensitive small-bore ceramic valve into, the restoring force of valve can be realized by spring power or by the restoring force of air bag diaphragm.For anti-air pressure transfer tube gas leakage processed, after gas leakage, water level causes rising in air pressure transfer tube and has been full of water, water gravity is closed low discharge inching valve, therefore should open the hydrophobic spiral cover of air pressure transfer tube end when maintenance, and in air pressure transfer tube, only have gas at ordinary times, therefore realize the water saving object of controlling high water tank without overflow pipe current.
