The specific embodiment

The operation principle of the utility model (hand) is described below in conjunction with Fig. 3.Triangle vavle 28 among Fig. 3 is not as a part of the present utility model, not essential, only use when making things convenient for I﹠M, so open under the normal condition, manual exhaust valve 3 is only opened when exhaust, all the other times are what close, and charging connector (valve inside) 2 is actually an one way stop peturn valve, can only inflate and outwards exhaust in closed container 4.Operating procedure is: before using hot water, one, with inflator 5 through inflated hose 6, charging connector 2 is inflated in closed container 4, because solar water heater water tank 12 has permeability cell 13 to communicate with atmosphere, so the air pressure in the closed container 4 are the interior formed hydraulic pressure of water-head of water level and the closed container 4 in the solar water heater water tank 12, air pressure in closed container 4 is because inflator 5 passes through inflated hose 6, charging connector 2 is constantly inflated in closed container 4 and is increased, when pressure that closed container 4 internal gas pressures are produced greater than the water heater water-head, water in the closed container 4 is because of being subjected to the pressure process water pipe connector 1 of gas, connect flexible pipe 14, triangle vavle 28, threeway 29, solar water heater water pipe 11, be back in the solar water heater water tank 12 and and mix with hot water, lasting inflation makes water level reduction in the closed container 4, stops inflation when water level is reduced to the zero graduation of water level observation window 7.Illustrate in the closed container 4 it is air this moment, and be cold water in the solar water heater water pipe 11; Two, open manual exhaust valve 3, communicate with atmosphere in the closed container 4 at this moment, air pressure reduces, so the hot water in the solar water heater water tank 12 is through solar water heater water pipe 11, threeway 29, triangle vavle 28, connect flexible pipe 14, water pipe connector 1 flows in the closed container 4, when water level observation window 7 shows water level to full scale, close manual exhaust valve 3, this moment, closed container 4 interior air pressures caused pressure to raise because of constantly entering of water, when whiles such as air pressure and hydraulic pressure, water will no longer flow in the closed container 4, because of the volume of closed container 4 capacity greater than water in the solar water heater water pipe 11, illustrate this moment in the solar water heater water pipe 11 all cold water oneself flow in the closed container 4, and be the hot water that flows out by solar water heater water tank 12 in the pipe.Three, open the hot water tap who is connected with hot water outlet 210, flowing out from hot water outlet 210 has been exactly hot water.Before using hot water, once just can reach the purpose of water saving by the above-mentioned steps operation at every turn.The operation principle of the utility model self-action is described below in conjunction with Fig. 2.So-called self-action is exactly by circuit control, after pressing the one-shot button, stops this working procedure of exhaust when stopping inflation and exhaust, high water level in the time of just realizing inflation, end water level automatically.K switch is arranged in the circuit, start button SB, relay J (220V), J1 (12V), J2 (12V), electric air pump 25 (220V), magnetic valve 23 (220V), isolating transformer B (220V/12V), triode V1, V2, rectifier bridge heap D, high water level conduction probe 8, low water level conduction probe 9, water, the electric conductor 10 of closed container 4 inner bottom parts.And shown in the circuit diagram among Fig. 2, connect.The effect of isolating transformer B is because high water level conduction probe 8 directly contacts with water with low water level conduction probe 9, so for the isolating transformer of safety employing at output safety voltage, at output voltage is that the isolating transformer of safe voltage all can use, but requires the coil working voltage of J1, J2 and the output voltage of isolating transformer B to be complementary.Because of the water pipe method of attachment of the utility model self-action identical with hand, so no longer repeat.Because in the closed container 4 to, position have three kinds may: one, water level is lower than low water level, and just the water surface all not have and high water level conducts electricity probe 8 and low water level and conducts electricity probe 9 and contact; Two, water level is between high water level and low water level, and just the water surface contacts with low water level conduction probe 9, but does not contact with high water level conduction probe 8; Three, water level is higher than high water level, contacts with low water level conduction probe 9 with high water level conduction probe 8 when just the water surface is watched.

May set forth one by one with regard to these three kinds below.

One, when water level is lower than low water level, connect power supply, open K switch, power on circuitry, isolating transformer B has voltage output, but because of high water level conduction probe 8 does not all have to contact with the water surface with low water level conduction probe 9, that is to say that the base stage of triode V1 is not because conduction probe 8 constitutes the loop by water and closed container inner bottom part metallic conductor 10, thereby do not obtain making the triggering signal of triode V1 conducting, so triode V1 ends relay J 1 coil losing electricity, as a same reason, relay J 2 coils do not contact dead electricity with water because of conduction probe 9 yet, close so J1 is normally closed, and J2 often cut-offs out, because relay J 2 is often cut-off out, so it is electric that the relay J coil can't get, air pump 25 is electric can not the startup because of the relay J coil can't get, and relay J is normally closed closes.Magnetic valve 23 is because relay J 1 is normally closedly closed, normally closed the closing of relay J and must establish by cable and open, air in the closed container 4 is discharged through magnetic valve 23 by hydraulic pressure, water level rises, when water level rises to the water surface and low water level conduction probe 9 and contacts, situation just may be identical with second kind, so introduce in second kind of possibility below, no longer repeat here.

Two, when water level is between high water level and low water level, open K switch, power on circuitry, low water level conduction probe 9, water, closed container inner bottom part conductive plate 10 forms the loop, triode V2 base stage obtains triggering signal and conducting, (resistance of life water is generally about 250K ohm, water is regarded as dropping resistor between transistor base and the positive pole, in the circuit of direct current 12V, when the triode model is j13007-2, the relay model is under the state of jqc-3f (t73), through overtesting, utilizing contacting or disconnecting effectively and the stably through and off of control relay of base stage and water) relay J 2 coils get, relay J 2 is often opened adhesive, because of high water level probe 8 does not contact with water so triode V1 can't conducting, relay J 1 coil losing electricity, before pressing start button SB, because of the normally closed of normally closed and relay J 1 of relay J closed, so magnetic valve gets electric and opens, air is discharged because of the unlatching of magnetic valve 23, if do not press start button SB always, water level will continue because of the unlatching of magnetic valve 23 to rise becomes the third possibility until being higher than high water level, but when pressing start button SB, electricity is through K switch, start button SB, relay J 2 is often opened, the relay J coil forms the loop, the relay J adhesive, the adhesive that air pump often leaves because of relay J starts, the adhesive self-locking that another is often opened because of relay J of relay J coil.So air pump is able to continuous firing.And magnetic valve cuts out because of the normally closed disconnection dead electricity of relay J, so the water level in the closed container 4 reduces because of the continuous firing of air pump, when water level is lower than low water level, low water level conduction probe 9 can not contact with water, relay J 2 coils end dead electricity because of triode V2, relay J 2 is often cut-off out, the relay J coil losing electricity makes and often cut-offs out, air pump quits work, magnetic valve is also because relay J, J1 is normally closed closes and must establish by cable and open, and stops inflation thereby finish, and this working procedure of beginning exhaust continues rising when being higher than high water level when the water level of closed container 4, high water level conduction probe 8, water, closed container inner bottom part electric conductor 10 makes triode V1 triggering and conducting, relay J 1 coil gets electric, relay J 1 normally closed disconnection, and magnetic valve 3 dead electricity are closed.Whole working procedure (stopping exhaust when stopping inflation and exhaust, high water level when inflation, end water level) finishes.

Three, when water level is higher than high water level, open K switch, because high water level conduction probe 8 all contacts with the water surface with low water level conduction probe 9, so relay J 1 and relay J 2 coils can both be because of triode V1, the conducting of V2 and, relay J 1 normally closed disconnection, magnetic valve dead electricity and closing, when pressing start button SB, the time, because of relay J 2 often open adhesive, the relay J coil gets electric, electric air pump 25 is often opened adhesive startup work because of relay J, beginning is inflated in closed container 4, simultaneously, another often opens the adhesive self-locking relay J, the normally closed disconnection of relay J, when water level drops between high water level and the low water level, high water level conduction probe 8 can not contact with the water surface, triode V1 by and cause relay J 1 coil losing electricity, relay J 1 normally closed closing, but because of the normally closed off-state that is in of relay J in the circuit therewith of connecting, so magnetic valve 23 still cuts out because of dead electricity.When water level continues to drop to when being lower than low water level, low water level conduction probe 9 does not contact with the water surface, triode V2 ends, the Chang Kaiyin coil losing electricity of relay J 1 and disconnecting, so the relay J coil losing electricity makes normally closed closing simultaneously, often cut-offs out the relay J self-locking releasing, electric air pump 25 quits work, magnetic valve 23 is because of getting electric the unlatching simultaneously, and the water in the solar water heater water tank is back in the closed container 4, when water level rises to high water level because of the unlatching of magnetic valve 23, because of high water level conduction probe 8 contacts with the water surface, triode V1 conducting, relay J 1 coil gets electric, so relay J 1 normally closed disconnection, magnetic valve 23 dead electricity and closing stop exhaust.Thereby the entire work process that stops to arrange when stopping to inflate also exhaust, high water level when having finished inflation, end water level.

So as long as K switch is in opening, under the situation of power on circuitry, water level always is in the high water level state in the closed container 4.Only water level just may be lower than under the high water level behind new installation the utility model or repairing the utility model, but still can return to the high water level state because of power on circuitry makes water level.The normal course of work is that original state is the course of work of high water level state.
