The invention has the beneficial effects as follows: make heat storage water tank inside forever no longer bear high pressure without under water state, effectively prevent the booster phenomenon of cistern free solar energy vacuum tube, the fatigue, the burn into that effectively solve storage-type electric water heater heat storage water tank puncture drainage, and reduce pressure release bleeder quantity, reduce or remit the incidence of floods, reduce the generation of electric leakage accident, improve security performance.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is circuit catenation principle figure of the present invention;
In figure, 1 heat storage water tank, 2 enter cold water pipes, 3 hot-water outlet pipe roads, 4 normally closed solenoid valves, 5 relief pipelines, 6 check valves, 7 pressure switches, 8 normally open solenoid valves, 9 protruding bulges, 10 power supplys, 11 pressure-reducing valves, 12 first safety valves, 13 first threeways, 14 second safety valves, 15 second threeways.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises heat storage water tank 1, heat storage water tank 1 outside is connected to into cold water pipes 2 and hot-water outlet pipe road 3, enter cold water pipes 2 and be provided with normally closed solenoid valve 4, hot-water outlet pipe road 3 is connected in parallel to relief pipeline 5 successively along water (flow) direction, is connected in series with check valve 6, is connected in parallel to pressure switch 7, relief pipeline 5 is provided with normally open solenoid valve 8.Heat storage water tank 1 top is provided with protruding bulge 9, and upper end, hot-water outlet pipe road 3 is stretched in protruding bulge 9.Normally closed solenoid valve 4 is connected with being in series with pressure switch 7 and power supply 10 successively after normally open solenoid valve 8 parallel connection.Enter cold water pipes 2 and be provided with the pressure-reducing valve 11 being positioned at normally closed solenoid valve 4 front portion along water (flow) direction.Enter cold water pipes 2 and be provided with the first safety valve 12 being positioned at normally closed solenoid valve 4 rear portion along water (flow) direction.Hot-water outlet pipe road 3 to be in parallel with relief pipeline 5 by the first threeway 13 and to be connected.The second safety valve 14 is provided with between check valve 6 and the first threeway 13.Hot-water outlet pipe road 3 to be in parallel with pressure switch 7 by the second threeway 15 and to be connected.Do not have check device in normally open solenoid valve 8, normally closed solenoid valve 4 is provided with check device, and power supply is 12V.
Adopt the full-automatic pressure-bearing of a kind of water heater heat storage water tank of the present invention operational system with no pressure, check valve 6 can be replaced by motor-driven valve, now, the opening and closing of motor-driven valve and normally closed solenoid valve 4 and normally open solenoid valve 8 synchronous.When opening hot-water valve with during water, pressure drop in hot-water outlet pipe road 3, pressure switch 7 resets and switches on power 10, the energising of water inlet normally closed solenoid valve 4 is opened path and enter cold water in heat collector or heat storage water tank 1, normally open solenoid valve 8 switches on power simultaneously and cuts out the path of outwards excretion, allow current lead to if check valve 6 is opened hot water passageway for 10 rotations that also switch on power during motor-driven valve simultaneously, now system is closed operation, only have terminal hot-water valve to open to there are flowing out for.When complete with water, close out hot-water valve, now water can only enter can't get out, under intake pressure effect, in whole system, pressure raises rapidly, when rising to the setup parameter of pressure switch 7, internal circuit disconnects the power supply to the power supply of normally closed solenoid valve 4, normally open solenoid valve 8, motor-driven valve, normally closed solenoid valve 4 closes water inlet, motor-driven valve rotates or (blocking) hot-water outlet pipe road 3 current internal channel is closed in the effect of check valve 6 spring close to the inner portion, reset after normally open solenoid valve 8 power-off and to fetch boiling water circulation flow path pressure release, pressure and portion of water discharged to floor drain (external world).Owing to not having check device in normally open solenoid valve 8, the inside of heat collector or heat storage water tank 1 is communicated always with air, the inside reaching heat collector or heat storage water tank 1 is always the object of normal pressure.Because check valve 6 or motor-driven valve therefrom block hot-water outlet pipe road 3 water passage, in the hot-water outlet pipe road 3 of motor-driven valve or check valve 6, the second threeway 15 being connected with pressure switch 7, pressure switch 7 valve block position, the second threeway 15 to terminal penstock, pressure is not released, also maintain pressure to exist, for start up system is prepared next time.Heat storage water tank 1 now or heat collector are open type state.The moisture expanded out after solar heat-collection, electrical heating, air-source heating is discharged along hot water pipeline in water tank, through normally open solenoid valve 8 discharged to floor drain (external world), make forever there is no pressure in heat storage water tank 1 or vacuum tube collector, cause the fatigue phenomenon of long-term pressurized can not to heat storage water tank 1, vacuum heat collection pipe booster can not be made.Heat storage water tank 1 inside is made forever no longer to bear high pressure, and fatigue is shut off oneself from society without under water state.Greatly reduce the speed that water quality punctures metal erosion, reduce once the speed of leaking of water tank quality problems appearance, and the unlikely generation causing floods, extend the service life of water tank greatly.This device is utilized to change stainless steel, carbon steel sheet material into pp macromolecule modified plastic material, greatly for country has saved steel, reduce the welding of metal in production and processing, the production technology of the complexity of enamel, save part manpower, reduce cost, improve electrical apparatus insulation performance, decrease potential safety hazard.The defect of virgin metal water tank processing technology makes corrosion puncture to leak, and domestic and international technology all cannot overcome so far, and blank both domestic and external has been filled up in this technological invention thus.Next time, water only need open hot-water valve, so circulated.Operate extremely easy, do not change traditional occupation mode, simple structure, fault rate is extremely low.
