Description
Affiliated technical field
The utility model relates to that a kind of static state is opened wide and the storage water heater of Dynamic Closed, in water storage tank and with its straight-through container in the feedwater heating.For opening wide, it was automatically converted to the Dynamic Closed state that cold water (running water) water inlet ejects the hot water effluent when one is opened with water valve when water was promptly not static.
Background technology
At present, known storage water heater is divided into open type and closed.Open type adopts morely in solar vacuum-tube water heater, closedly adopts in electric heater.They all have electrothermal tube at water storage tank, and the former uses as auxiliary heating.The closed pressure-bearing type that also claims, its water intaking valve is a non-return because system seals, when water not except bearing the static pressure (2-3kgf/cm of running water own
2), producing additonal pressure owing to add thermal expansion in addition, this just requires water-heater system to bear greater than 7-8kg/cm
2Pressure.General electric heater requires greater than 8kgf/cm
2, also to add pressure relief safety valve for preventing to add the accident of pining for may superpressure causing.It requires very high to water storage tank, be critical process, the cost height.Advantage is that cold water (running water) water inlet ejects hot water, and hot water effluent's pressure is big.Therefore open type is not born pressure and is claimed non-bearing type, as the solar vacuum-tube water heater of leaking water in vacuum tube, because so big pressure can not be born with the water storage tank junction in vacuum tube and it, therefore can only adopt unlimited non-bearing type.It utilizes height water-head between storage tank and the hot water water consumption device to produce pressure hot water is flowed out.Its storage tank and a direct vacuum pumping pipe thermal-collecting tube that inserts it just must be placed on highest point, otherwise the hot water outflow pressure is little, and cleaning action is not strong, moisturizing.Water storage tank generally is placed on the roof, and connecting pipe is very long, and all outdoor, heat radiation is many, and can ice stifled winter.Because the restriction of installation site, can not make split typely as balcony wall-hanging, not that the resident family of top layer can not use.At present, pressure type vacuum tube solar water heater mostly adopts following method, promptly absorbs heat in vacuum tube by the superconduction hot material and heat is passed to water in the storage tank again.Solar energy is not directly passed to water, and it is high and cost is high to adopt the thermal efficiency, so be not extensive use.
Summary of the invention
In order to solve pressure-bearing storage water heater's problem of big pressure, the utility model provides a kind of static state to open wide and the storage water heater of Dynamic Closed.It opens wide when water is promptly not static, does not bear pressure, only bears very little dynamic pressure during water.Material, technology that it requires are suitable with the non-bearing type water heater, so cost is also the same substantially, but have the advantage of pressure-bearing type.
The technical scheme that its technical problem that solves the utility model adopts is: the hot water outlet at the water storage tank top is connected to hot water effluent's total pipeline by a closed type magnetic valve, and a normally closed type pressure switch is housed on the outfall sewer road; Cooling water inlet at water tank bottom also is connected to the pressure cold water pipes by a closed type magnetic valve; Draw discharger from water tank bottom by a normal-open electromagnetic valve, its outlet is than the top height of water storage tank.These three magnetic valve synchronization actions, promptly their power switch is same, is exactly the normally closed type pressure switch on the outfall sewer road.Because closed is the dynamical state that cold water ejects hot water when water, pressure is at 0.2kgf/cm
2About, so establish the parameter of this pressure switch be: pressure is greater than 0.4kgf/cm
2Disconnect, less than 0.1kgf/cm
2Connect.Water inlet is opened and is used water valve first, and outfall sewer does not have pressure in the road, and pressure switch is connected, and the closed type magnetic valve opens the while normal-open electromagnetic valve and cuts out, and advances cold water up to filling it up with.The closeall water valve of using, outfall sewer road internal pressure begin to increase, when greater than 0.4kgf/cm
2The time pressure switch disconnect, all magnetic valve dead electricity, the closed type closed electromagnetic valve, normal-open electromagnetic valve is opened, water heater is opening-wide state.Because the strain of container itself has low amounts of water and overflows from discharger, pressure drops to zero (disregarding level pressure).But at this moment outfall sewer is a closed state, and inside water pressure still keeps greater than 0.4kgf/cm
2Open any and use water valve when water, the pressure in the outfall sewer road drops to very soon less than 0.1kgf/cm
2, pressure switch is logical, and the closed type magnetic valve is opened, and normal-open electromagnetic valve is closed.This moment, whole water heater comprised that the outfall sewer road is the Dynamic Closed state, was that cold water ejects hot water conditions, and pressure is dynamic pressure, approximately 0.2kgf/cm
2About.(establish running water static pressure 2kgf/cm
2About).Close and use water valve, situation as described above.Removing the outfall sewer road will bear greater than 0.4kgf/cm for a long time
2Pressure, water heater opened wide in static (not water) time, did not bear pressure, even there is electrothermal tube (or solar energy) also like this in heating.Only bear very little dynamic pressure during water, about 0.2kgf/cm
2Certainly in very short time 0.4kgf/cm is arranged at the pass closed procedure
2Pressure.
The beneficial effects of the utility model are that the water heater made from non-pressure-bearing storage water heater's material, technology and cost reaches pressure-bearing storage water heater same effect.Especially for the solar vacuum-tube water heater of in vacuum tube, leaking water, overcome vacuum tube and it and water storage tank junction and born the little obstacle of pressure and can be made into and have pressure-bearing type functional hot water device, as balcony wall-hanging etc.
