Description
Technical field
This utility model relates to solar energy heat utilization field, particularly a kind of micro-pressure-bearing type solar water heater of domestic.
Background technology
At present, known domestic solar water heater divides pressure-bearing type and non-bearing type two kinds, and non-bearing type is the most universal
The one used, structure generally comprises water tank, support and the row's all-glass vacuum solar collection being directly inserted in inner water tank
Heat pipe.The solar water heater of this non-bearing type is typically mounted at the top of building, the pressure of outlet depend on water tank with
High-low water level between shower is poor, and hot water effluent's pressure is little, and this mounting means greatly limit range and bathing
Comfort level.And must have a steam vent on the water tank of this solar water heater, have impact on whole heat to a certain extent
The heat insulation effect of water heater system.Pressure type vacuum tube solar water heater can overcome these defects of non-bearing type, typically it with
Pressure cold water source (tap water) remains and communicates, and when hot water outlet is closed, whole system to bear big pressure.At collection
In thermal process, along with the rising of water tank temperature, water tank internal pressure is gradually increased, even can be more than 0.6MPa.Although solar energy
Vacuum heat collection pipe design is pressure is 0.6MPa, but but can not be the most pressure, so pressure-bearing type solar water heater is generally
Indirect heat exchange, typically arranges heat exchanger components inside water tank, such as heat exchange jacket or coil pipe, in heat collector, vacuum tube is the most directly leaked water,
Set metal flow passage pipe in but, add that sheet metal thickness is usually more than 3 times of non-pressure water tank, cause the thermal effect of whole system
Rate is relatively low, and manufacturing process is complicated, and cost is higher, and whole system bears high pressure for a long time, and the life-span is relatively low.Patent No.
The Chinese utility model patent description of ZL200520087678.4 discloses one " Novel system bearing water heater ", including non-
Press-bearing water tank, has inner bag, non-pressure tank top to have relief valve in water tank, install decompression on the water inlet pipe of non-pressure water tank
Valve, water inlet pipe, in the bottom of non-pressure water tank, is directly connected to inner bag, and the bottom of non-pressure water tank is also with solar energy heat collection pipe even
Connect.The outlet pipe of this " Novel system bearing water heater " is positioned at the top of water tank end cap, and relief valve also is located at the top of water tank,
Water level is full-water level, and without air layer in water tank, along with the temperature of Water in Water Tanks raises and expands, pressure also raises, and exceedes safety
During the setting pressure of valve, relief valve draining, whole temperature-rise period has swelling water to discharge, waste water resource；Because of without temperature safety
Protection, when water temperature is increased to boiling point, pressure raises suddenly, and relief valve has little time draining can cause evacuated solar collecting tube and non-
The destruction of press-bearing water tank；When additionally tap water is surprisingly cut off the water, water inlet pipe water can flow backwards, and easily inhales flat water tank.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of structure letter
Single, low cost of manufacture, micro-pressure-bearing type solar water heater of life-span length.
For solving above-mentioned technical problem, the technical scheme that this utility model is taked is: micro-pressure-bearing type solar water heater, bag
Including water tank, support, vacuum solar collector tubes, watering pipeline and drainage pipeline, described vacuum solar collector tubes is directly inserted into water
In case, being provided with outlet pipe on water tank, in water tank, the above water volume to tank top suitable for reading of outlet pipe is that water tank is total
The 15%～45% of volume, is provided with a temperature, pressure relief valve in the centre position of radiator end, and described watering pipeline is arranged
Having an air relief valve, described drainage pipeline is connected with outlet pipe.Air relief valve is, by regulation, inlet pressure reduces to a certain needs
Outlet pressure, and rely on the energy of medium itself, make outlet pressure automatically keep stable valve；During bathing, water is from Shang Shui
Pipeline enters water tank, ejects water from outlet, and temperature, pressure relief valve prevents water tank temperature too high or pressure is excessive, sets when exceeding
Regularly, valve event, the part water of inner water tank, gas are discharged at pressure relief opening and makes inner bag be maintained at certain pressure limit
In, inner bag is played a very good protection.
Preferably, described watering pipeline is additionally provided with a check valve.Check valve prevents from inhaling flat water tank because of aqueous reflux.
Preferably, described vacuum solar collector tubes is complete glass vacuum sun thermal-collecting tube or all-glass heat pipe vacuum sun set
Heat pipe.
The beneficial effects of the utility model are: by regulation air relief valve, control the pressure of water inlet of water tank in the pressure set
Power scope, in water tank, outlet pipe is suitable for reading above water to volume is water tank total measurement (volume) 15%～the 45% of tank top, protects
Having demonstrate,proved the space above water suitable for reading of outlet pipe in water tank is air, during closedown water, along with the temperature of water rises, in water tank
Pressure gradually rises, and due to the compressibility of air, is not result in that the pressure caused because of the expansion of Water in Water Tanks raises suddenly, protects
Demonstrate,prove in whole temperature-rise period the pressure of water tank not over setting pressure；Temperature, pressure relief valve prevent water tank temperature too high or
Pressure is excessive, it is to avoid the excessive saturation pressure produced when water temperature the reaches boiling point destruction to water tank；All-glass vacuum is too
Sun thermal-collecting tube or all-glass heat pipe vacuum solar collector pipe all can meet the pressure-bearing demand of system, all-glass heat pipe vacuum sun set
Heat pipe is because of anhydrous in pipe, it may also be used for severe cold area；Because whole system pressure is relatively low, water tank without heat exchanger, water tank sheet material without
Need to be according to common bearing type water tank selection, can be the most thinning, cost-effective, last a long time.
