Technical field

The utility model relates to a kind of device that solar water heater is carried out upper water and cut off the water.

Background technology

At present, the water-supply apparatus that solar water heater is used, having some is complete manual mode, by controlling manually water intaking valve, drives valve during low level, closes valve when high-order.This device needs special messenger to nurse, once water has been expired, forgets pass valve, causes and metals run out, and causes waste.Some takes electronic control mechanism, all needs all the time energising, consumes electric energy.

Summary of the invention

The problems referred to above that exist for solving existing water-supply apparatus, the utility model provides a kind of solar water heater automatically to go up stopping device, its technical scheme adopting is: comprise water management bellows, upper water management power spring, the control bellows of cutting off the water, the lever back-moving spring of cutting off the water, upper water lever, the lever of cutting off the water, montant, folding lever and sluicing needle-valve, upper water management bellows be positioned at water management power spring directly over, upper water management bellows is communicated with the bottom of upper hose, the left end of upper water lever is between upper water management bellows and upper water management power spring, cut off the water control bellows be positioned at the lever back-moving spring of cutting off the water directly over, cut off the water and control the bottom that bellows is communicated with overflow pipe, the left end of lever of cutting off the water is controlled bellows and cuts off the water between lever back-moving spring cutting off the water, cut off the water and control the bottom connection sluicing needle-valve of bellows, the right-hand member of upper water lever and the upper end of montant are hinged, the cut off the water right-hand member of lever and the lower end of montant is hinged, the left end of folding lever and the center of montant are hinged, right-hand member and the water supply valve of folding lever are hinged.

The utility model utilizes lever principle, adopts mechanical transmission mode, and water level is low during to setting value, breaks the balance of upper water management lever, and by spring force, valve is driven in realization.Water is full from overflow indicator tube flows out, and breaking cuts off the water controls the balance of lever, by the power realization of overflow water, closes valve.The utility model, without power supply, is kept an eye on without special messenger, both can make to cut off the water and have wide accommodation, energy-conserving and environment-protective, reliable operation, feature simple in structure in solar water heater realization automatically.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1, this device comprises water management bellows 1, upper water management power spring 2, cuts off the water and control bellows 3, the lever back-moving spring 4 of cutting off the water, upper water lever 5, the lever 6 of cutting off the water, montant 7, folding lever 8 and sluicing needle-valve 10.Upper water management bellows 1 be positioned at water management power spring 2 directly over, upper water management bellows 1 is communicated with the bottom of upper hose 11, the left end of upper water lever 5 is between upper water management bellows 1 and upper water management power spring 2, cut off the water control bellows 3 be positioned at the lever back-moving spring 4 of cutting off the water directly over, cut off the water and control the bottom that bellows 3 is communicated with overflow pipe 12, the left end of lever 6 of cutting off the water is controlled bellows 3 and cuts off the water between lever back-moving spring 4 cutting off the water, cut off the water and control the bottom connection sluicing needle-valve 10 of bellows 3, the upper end of the right-hand member of upper water lever 5 and montant 7 is hinged, the cut off the water right-hand member of lever 6 and the lower end of montant 7 is hinged, the center of the left end of folding lever 8 and montant 7 is hinged, the right-hand member of folding lever 8 and water supply valve 9 are hinged.

When the water of solar water heater is not finished, upper water lever 5 and cut off the water lever 6 all in equilbrium position, both go up the downward pressure of water management bellows 1 and equaled the elastic force that water management power spring 2 makes progress, cut off the water and control the downward pressure of bellows 3 elastic force that lever back-moving spring 4 makes progress that equals to cut off the water, the needle-valve 10 that simultaneously sluices keeps suitable aperture.When the water of solar water heater runs low, in upper water management bellows 1, do not have water, its pressure is less than the elastic force of water management power spring 2, upper water lever 5 disequilibriums,, move on the left end of upper water lever 5 upwards under the effect of elastic force at upper water management power spring 2, the right-hand member of upper water lever 5 promotes montant 7 downwards and moves down, and then the left end of folding lever 8 is moved down, and on the right-hand member by folding lever 8, moving and open water supply valve 9, water heater starts upper water.After waterborne expiring, a small amount of water flows into cut off the water from overflow indicator tube 12 controls bellows 3, the pressure of controlling bellows 3 of making to cut off the water is greater than the elastic force of the lever back-moving spring 4 of cutting off the water, lever 6 disequilibriums of cutting off the water, control under the downward pressure of bellows 3 cutting off the water, and the left end of the lever 6 of cutting off the water moves down, the right-hand member of lever 6 of making to cut off the water upwards promotes montant 7, and then make to move on the left end of folding lever 8, the right-hand member by folding lever 8 moves down and closes water supply valve 9, and water heater stops upper water.Subsequently, sluicing needle-valve 10 is controlled the water emptying in bellows 3 lentamente by cutting off the water, and cuts off the water to control the downward pressure of bellows 3 and reduce, and the lever back-moving spring 4 of the cutting off the water lever 6 that makes to cut off the water returns to equilbrium position.Meanwhile, owing to again having water in upper water management bellows 1, the pressure of water management bellows 1 is increased, thereby upper water management bellows 1 make water lever 5 return to equilbrium position.
