Therefore the utility model is characterized in that the automatic water-control device for water tank of solar water-heater can be used without the electricity, and can be installed indoors; the use, installation and maintenance are very convenient, etc.

Description

The solar water heater water tank automatic water control device

One, technical field

The utility model is the automatic water control device of water on a kind of solar water heater water tank.

Two, background technology

Solar water heater water tank is controlled water automatically and is meant that water tank is filled with and can stops to go up water behind the water automatically.The product that is used for controlling automatically water at present mainly divides two classes: magnetic valve fluid level controller, float switch.The shortcoming that electromagnetism dodges fluid level controller is: can't use the cost height during power failure.The shortcoming of float switch is: outdoor (generally installing at roof), be not easy to install and maintenance.

Three, summary of the invention

The purpose of this utility model is for water on the solar water heater water tank provides a kind of not electricity consumption, can be easy for installation and maintenance the solar water heater water tank automatic water control device that cost is low in indoor installation.

For achieving the above object, the technical scheme that the utility model is taked is: be made up of housing, dividing plate, upper hose, porcelain core water valve, outdoor handle, inner handle, clockwork spring, lever, rotating shaft, stressed dish, driving lever, last overflow pipe, following overflow pipe etc.Dividing plate is fixed in the housing, and housing is divided into left and right two Room, and upper hose is contained in the left indoor of housing, and upper and lower two ends of upper hose stretch out housing, and the lower end of upper hose is communicated with the water source, and the upper end of upper hose is communicated with the water tank of solar water heater.The porcelain core water valve is contained in the interior upper hose of housing, is fixed with inner handle, outdoor handle on the valve shaft of porcelain core water valve, and inner handle is in housing, and outdoor handle is in hull outside; One end of clockwork spring is fixed on the valve body of porcelain core water valve, and the other end of clockwork spring is fixed on the inner handle.Upside, its upper end that last overflow pipe is fixed on the housing right ventricle is communicated with water tank overflow pipe, its lower end is communicated with the housing right ventricle.Downside, its upper end that following overflow pipe is fixed on the housing right ventricle are communicated with the housing right ventricle.Rotating shaft is fixed on the dividing plate, and lever passes dividing plate and is contained in the rotating shaft, and lever is fixed with stressed dish on an end of housing right ventricle, and stressed dish is at the downside of last overflow pipe, and stressed dish is provided with aperture.Lever is fixed with driving lever and withstands inner handle on an end of chamber, a housing left side.Driving lever stretches out housing.

When the utility model uses, open the water source, water is through the water tank water filling of upper hose to solar water heater, after water tank is filled with water, water flows out from the overflow pipe of water tank, flow to stressed dish through last overflow pipe, and stressed dish is under impact force of water flow and gravity effect, making lever is the center swing with the rotating shaft, the other end of lever drives on the driving lever and moves, and throws off inner handle, and inner handle drives valve shaft and rotates under the clockwork spring effect, close the porcelain core water valve, the water at water source is no longer to the water tank water filling.And from the water that last overflow pipe flows down, flow down by the aperture on the stressed dish, through overflow pipe discharge down.The water that dividing plate can block the right ventricle flow to left chamber, in order to avoid parts such as clockwork spring get rusty.When on the needs during water, rotate outdoor handle, drive valve shaft and open the porcelain core water valve, valve shaft drives inner handle simultaneously, and inner handle is dragged tight clockwork spring and getd out of the way driving lever, and driving lever is moved down, unclamp outdoor handle, inner handle withstands driving lever under the clockwork spring effect, and the water at water source again can be through upper hose to the water tank water filling.

Because the utility model is provided with stressed dish at the downside of last overflow pipe, utilize the impulsive force of the water that overflows, make driving lever break away from inner handle by stressed dish by lever, inner handle is closed the porcelain core water valve automatically under the clockwork spring effect.Therefore, the utlity model has not electricity consumption, can be in indoor installation, easy to use, characteristics such as installation, maintenance is convenient, and cost is low.

Five, specific implementation method

As shown in drawings, the utility model is made up of housing 1, dividing plate 11, upper hose 5, porcelain core water valve 2, outdoor handle 13, inner handle 4, clockwork spring 3, lever 9, rotating shaft 7, stressed dish 10, driving lever 6, last overflow pipe 2, following overflow pipe 12 etc.Dividing plate 11 is contained in the housing 1, and housing 1 is divided into left and right two Room.Upper hose 5 is contained in the left indoor of housing 1, and its upper/lower terminal stretches out housing 1, and the lower end of upper hose 5 is communicated with the water source, the upper end is communicated with the water tank of solar water heater.Porcelain core water valve 2 is contained in the housing 1 interior upper hose 5.Be fixed with inner handle 4, outdoor handle 13 on the valve shaft of porcelain core water valve 2, inner handle 4 can form certain angle with outdoor handle 13, and inner handle 4 is in housing 1, and outdoor handle 13 is outside housing 1.One end of clockwork spring 3 is fixed on the valve body of porcelain core water valve 2, and the other end is fixed on the inner handle 4.Last overflow pipe 8 is fixed on the upside of housing 1 right ventricle, and is communicated with the right ventricle, and the upper end of last overflow pipe 8 is communicated with the overflow pipe of water tank.Following overflow pipe 12 is fixed on the downside of housing 1 right ventricle and is communicated with the right ventricle.Rotating shaft 7 is fixed on the dividing plate 11, and lever 9 passes dividing plate 11 and is contained in the rotating shaft 7, and lever 9 is fixed with driving lever 6 on an end of housing 1 right ventricle, and withstands inner handle 4, and driving lever 6 stretches out housing 1.Porcelain core water valve 2 is opened at this moment, when the water tank of solar water heater needs water filling, as long as open the water source, water just through upper hose to the water tank water filling, after water tank water is full, flow out from water tank overflow pipe, flow to stressed dish 10 through last overflow pipe 8, produce under impulsive force and the gravity effect at current, stressed dish 10 moves downward, by lever 9, driving lever 6 is moved up, throw off inner handle 4, inner handle 4 is under clockwork spring 3 effects, rotate valve shaft, porcelain core water valve 2 cuts out, the water at water source is no longer to the water tank water filling.When needing to the water tank water filling again, as long as rotate outdoor handle 13, outdoor handle 13 rotates valve shaft, open porcelain core water valve 2, but just water filling, simultaneously, valve shaft drives inner handle 4, drag tight clockwork spring 3, make inner handle 4 get out of the way driving lever 6, driving lever 6 moves down, and unclamps outdoor handle 13, inner handle 4 withstands driving lever 6, the state when making the utility model be returned to water under clockwork spring 3 effects.When not needing to fill with water to water tank, only with hand will move (because of driving lever stretches out housing) on the driving lever, makes driving lever 6 throw off inner handle 4, just can close porcelain core water valve 2.Otherwise when needing, only need to rotate outdoor handle 13, make inner handle 4 throw off driving lever and withstand driving lever 6 and just can to the water tank water filling.Therefore the utility model also can open or close to the water tank water filling at any time.
