Intake and exhaust conduit, observing and controlling element, valve body connect securing member etc., solve that water heater is breathed, measuring cell install realized aspect drawing and fixedly securing low-cost, highly integrated.The water heater manufacture craft is simplified to some extent, and unfailing performance improves.

Float-controlled automatic water feeding-supplying unit for solar water heater is when solar water heater feeds water, running water is by arriving the float-controlled water intaking valve body middle and lower part of giving to intake down, go up water conservancy diversion by the shelf stream chamber arrival of following water conservancy diversion location and locate shelf, enter in the water intaking selector valve group valve pocket by last valve port, this valve group is formed automatic selecting type triple valve by the opposite valve of a pair of keying, the valve at this valve top is under the effect of feed pressure, and valve closing stops up intake.Simultaneously, water-supply valve is opened under the pressure effect of water, and water is discharged, and realizes the choked flow feedwater of cold water at water tank bottom.Thereby avoided cold water to be flushed to water surface top layer, the phenomenon that the hot water or cold water mixes water occurred.Along with water level rises, float floats gradually, free floating condition is arranged to the plumbness transition, and float produces moment, overcome the friction of suspension ring and intake hanger and rotating shaft, slowly trend towards vertically, and overcome the elastic force of bellows, perpendicular to last intake top, along with water level rises, draught line acts on the compound spool location hanger securing member of connection, with compound spool traction under the buoyancy of float.When compound spool rises to a certain degree, the contract seal cover that covers capsule of the rubber bullet that is positioned at compound spool bottom contacts the sealing that coincide with the upper valve body lower sealing surface, water-feeding pressure acts on rubber closure and the location holder is weighed down, the seal cover distortion makes in the compound spool continuation and moves, and sealing surface coincide and seals on sealing surface on the spool and upper valve body.Form the two seals face by sealing surface on sealing surface and the valve body on rubber closure and lower sealing surface and the spool like this, guarantee its sealing state.In use, put when filling up in last sealing surface as incrustation scale, last sealing surface can not in time seal, because lower sealing surface has sealed anhydrous entering, under the effect of hydraulic pressure, the rubber bullet contracts and covers that capsule spool reducing expands and the upright sealing surface of upper valve body coincide, and has realized the sealing of feeding water.Put pad when poorly sealed when seal cover, it is small that it infiltrates water yield, will be contracted by the rubber bullet like this and cover that capsule spool reducing expands and identical sealing of the upright sealing surface of upper valve body.When sealing surface and rubber closure and lower sealing surface on sealing surface on the spool and the upper valve body all seal when bad, because lower sealing surface is the combination of flexible and rigidity, the effect of hydraulic pressure in addition, inflow is less, and this moment, last sealing surface but is in opening, hydraulic pressure acts on the rubber bullet and contracts and cover on the capsule spool like this, and the rubber bullet contracts and covers the capsule spool reducing is sealed, because its contact-making surface is bigger, it is again the taper state, even the particle advance expenditure is arranged, because its elasticity the phenomenon that seeps water can not occur yet, like this, can remain the sealing state of valve.

When water intaking, the hot water that compiles from the floatation type device for fetching water is under the effect of gravity, and the float-controlled water intaking valve open of giving simultaneously, be opened for the water intaking valve of installing on the water intaking selector valve group, and feed-water valve is closed, and has realized hot and cold water discharging respectively automatically.Thereby after having overcome the solar water heater feedwater, hot water floats on water heater top, and what emit during use but is cold water, and the inconvenient problem of using at once of hot water is arranged.Simultaneously, also solve feedwater and be flushed to the water heater top layer, the phenomenon of water occurred mixing.Because intake on the floatation type device for fetching water, therefore, has the phenomenon of incrustation scale outflow when not having heat-obtaining water.Solved the inconvenient technical barrier that uses at once in solar water heater feedwater back.Simultaneously, also can utilize the siphon periodical blowdown by the floatation type device for fetching water.

When water heater is cut off the water to intake pipe, no hydraulic pressure affacts rubber closure and the location holder is weighed down, move down with locating to hold in the palm under the gravity effect of weighing down at rubber closure capsule self elastic force, last sealing surface and rubber bullet contract and cover the identical state of the corresponding sealing surface disengaging of capsule spool, and water can enter in the valve pocket.At this moment, rubber closure is in the critical-sealing state.Work as tap water cut-off, when feed pipe bottom check valve or water intaking valve are not tight, under high water level self pressure, will there be water constantly to ooze out, air is mended automatically simultaneously, the water surface descends, the location holder is weighed down and has been lost the buoyancy of water effect, and compound spool further falls, and rubber closure breaks away from the state of coincideing, water in the water tank is mended into water inlet pipe and water outlet pipe the stuck phenomenon of compound spool when so just having prevented to cut off the water by the valve of opening.
