The specific embodiment

Embodiment one:

As shown in Figure 1, the emptier of solar water heater comprises charge valve 30 and utilizes the vent plug 40 of charge valve 30 inflations, vent plug 40 is installed in surge chamber 20 inside, surge chamber 20 comprises cylindrical shell 201 and lid 202 of a bottom opening, and lid 202 is detachable to be fixedly connected on the bottom opening of cylindrical shell 201.Surge chamber 20 is connected with the upper and lower conduit 24 of solar water heater, the top of surge chamber 20 is connected with outlet pass 11 places of the water tank of solar water heater 10, and be provided with down the mouth of a river 21, current are smooth at present in order to use, and the aperture at the following mouth of a river 21 should be greater than the aperture of upper and lower conduit; Also be provided with air inlet pipe 22 on the surge chamber 20, an end of air inlet pipe 22 stretches into surge chamber 20 inside and extends to down 21 places, the mouth of a river, and the top of air inlet pipe 22 is provided with the vent plug 40 that is used to seal down the mouth of a river, and the other end of air inlet pipe 22 is connected with first charge valve 30; Also be provided with an extension 23 on the surge chamber 20, extension 23 stretches into described solar water heater water tank 10 inside and extends to the top of water tank 10.

Be connected by loading line 32 between air inlet pipe 22 and first charge valve 30, loading line 32 is provided with an air bag 50, when first charge valve 30 is given 40 inflations of sealing vent plug, also, increased air storage amount in the whole gas circuit to air bag 50 inflations, when if slight gas leakage takes place in the flexible utricule 42 of sealing vent plug 40, air bag 50 can prevent vent plug gas leakage too much owing to stored a part of gas in a period of time, make vent plug break away from the inwall of surge chamber 30, prevent down that the mouth of a river 21 leaks.Another of air bag 50 act as the closed state that is convenient for people to distinguish down the mouth of a river 21, and when air bag 50 gassies, vent plug 40 is heaved, 21 sealings of the following mouth of a river; When not inflation of air bag 50, then to seal vent plug 40 and do not heave, the following mouth of a river 21 leads to.This method is convenient for people to select suitable mode of operation.

Also be connected with second charge valve 31 on the loading line 32, second charge valve 31 is in parallel with first charge valve 30, and two charge valves can be inflated vent plug 40, during use, two charge valves are installed in different places respectively, realize the multiple spot control to sealing vent plug 40.

As required, can connect a plurality of charge valves on the loading line 32, these charge valve parallel connections can be controlled the sealing vent plug.

In the present embodiment, the structure of vent plug as shown in Figure 2, vent plug 40 comprises cock body 41 and the flexible utricule 42 that is fixed together, flexible utricule 42 is communicated with air inlet pipe 22 and is fixed on the described air inlet pipe 22.Cock body 41 and flexible utricule 42 are installed in surge chamber 20 inside.

When charge valve 30 unaerateds, cock body 41 breaks away from the inwall of surge chamber 20, and the following mouth of a river 21 leads to, and when charge valve 30 was given vent plug 40 inflations, flexible utricule 42 was heaved, and promotes cock body 41 and is close on the inwall of surge chamber 20, and the mouth of a river 21 is sealed.

Be connected with on the outer face of cock body 41 and prevent that vent plug from moving the guider of hour offset, guider comprises a plurality of outer leads 43, on the outer face that is installed in cock body 41 of outer lead 43, outer lead 43 stretches into the inside of solar water heater water tank 10 from the following mouth of a river 21, outer lead 43 annular array also link together by a connecting ring 44.

Guider can be avoided sealing vent plug 40 and move hour offset, the following mouth of a river 21 bad sealings are close and cause drainage, and guider is installed in down the inside at the mouth of a river 21, and wave in water, can prevent the incrustation scale wall built-up, the mouth of a river 21 causes flowing water obstructed under stopping up.

The guider of vent plug has multiple structure in the present embodiment, the another kind of structure that the guider of vent plug has as shown in Figure 3, guider comprises an interior lead 45 that is installed in flexible utricule 42 inside, one end of interior lead 45 is fixed on the inner face of cock body 41, the other end is plugged on air inlet pipe 22 inside, has airflow clearance between the inwall of interior lead 45 and air inlet pipe 22.The length of interior lead 45 will guarantee, when charge valve was inflated, interior lead 45 can move and can not break away from the air inlet mouth of pipe with vent plug, and was this simple for structure, can effectively prevent the vent plug displacement, the phenomenon generation that causes down mouth of a river bad sealing to leak.

The operation principle of the utility model solar water heater emptier is: when on the solar energy during water, current flow into surge chamber 20 by upper and lower conduit 24, this at present the switch at the mouth of a river 21 do not influence water on the solar energy, if open at the following mouth of a river 21, current are flowed in the water tank 10 by the following mouth of a river 21 on the surge chamber 20 and extension 23, if the following mouth of a river 21 is closed, current enter water tank 10 by extension 23; During emptying, close the water source, 40 inflations of 31 pairs of sealings of first charge valve 30 or second charge valve vent plug, the flexible utricule 42 of sealing vent plug 40 is heaved, and the inwall that makes cock body 41 be close to surge chamber 20 is blocked down the mouth of a river 21, because some air of tank top; Under atmospheric effect, the water in extension 23 and the surge chamber 20 will be outside upper and lower conduit 24 effusers, and the direction of current is shown in arrow among Fig. 1; When using solar energy, bleed off the gas in the vent plug 40, the following mouth of a river 21 leads to, hot water in the water tank 10 enters surge chamber 20 by the following mouth of a river 21, flow out along upper and lower conduit 24, open with penstock 33, hot water flows out, because after the emptying, in the extension 23, in the surge chamber 20 and do not have storage of water in the upper and lower conduit 24, directly flow out hot water, compare with traditional solar water heater with penstock 33, the user does not need to wait for that the cold water in the water pipe drains, and directly just can use hot water.
