Description
Technical field
The utility model relates to solar water heater, particularly a kind of mechanical device preventing hot water overheated.
Background technology
Solar water heater enters huge numbers of families, deeply welcomed by the people, the solar water heater stood in great numbers in the roof that is seen everywhere in life.
But can find in water heater use at sun, the sun tanned by the sun and made the rising of the water temperature of solar water heater very fast summer.If water consumption is few, the cold water supplemented is also few, and the often energy accumulation of several days, the water temperature in water heater will be very high, even can reach 100 DEG C, occurs that steam is emitted in boiling.And too high temperature, easily cause the electric component sex change such as plastic water pipe accelerated ageing, level sensor, the phenomenon such as aging, shorten the service life of water heater; Meanwhile, carry out the water yield when water temperature is too high and supplement, neglect heat cold meeting suddenly and cause thermal-collecting tube to burst.Moreover if house-owner goes out, a period of time does not move in without water or new house finishing, and the continuous explosive evaporation moisture of solar water heater, wastes large water gaging, also can bring larger damage, even produce danger water heater.
Utility model content
The utility model object is to provide a kind of solar water heater automatic over-temperature protection, and when water temperature exceedes setting value, domination set heat pipe stops heat absorption automatically, to protect solar water heater.
Scheme of the present utility model is: the automatic over-temperature protection of a kind of solar water heater, comprise shutter and temperature control drive unit, shutter is equiped with on thermal-collecting tube of solar water heater, the control end of shutter is connected with the drive end of a temperature control drive unit, it is characterized in that: described temperature control drive unit comprises expansion of liquids pipe, tube connector, bellows, back-moving spring, push rod and shell, expansion of liquids pipe and bellows are welded into airtight integrated container, boiling point has been poured into lower than the low-boiling point liquid of 80 DEG C in the inside, bellows is connected with the drive end of push rod as temperature control drive unit, on the tank outer wall that temperature control drive unit is fixedly mounted on solar water heater or support, wherein expansion of liquids pipe is plugged in water tank, the control end connection for transmission of push rod and shutter.
Described low-boiling point liquid adopts methyl alcohol or ethanol, and be welded in airtight integrated container at expansion of liquids pipe and bellows after perfusion, gas, liquid proportional are between 1:1---2:1.
The utility model has the advantages that: in water tank, be provided with expansion of liquids pipe, when water temperature rises, temperature reaches the boiling point of the inside liquid, vaporizing liquid, volumetric expansion, bellows extends drivening rod, final promotion shutter is closed, and blocks thermal-collecting tube, prevents from continuing to absorb heat; When water temperature is lower than boiling point of liquid, steam cooling liquid, volume reduces, and bellows is shunk under the effect of back-moving spring, pulls connecting rod to be opened by shutter, thermal-collecting tube heat absorption work.The utility model make use of the vaporization of liquid, and whole temperature control drive unit adopts the structure of closed container, has high reliability and long-life advantage.
Accompanying drawing explanation
The utility model is described in further detail according to drawings and embodiments below.
Fig. 1 is the overall structure schematic diagram installing solar water heater after this device additional.
Fig. 2 is temperature control drive unit cold conditions structural representation.
Fig. 3 is the hot structural representation of temperature control drive unit.
Description of symbols in figure: 1 water tank, 2 shutters, 3 thermal-collecting tubes, 4 supports, 5 connecting rods, 6 temperature control drive units.
In temperature control drive unit: 601 expansion of liquids pipes, 602 tube connectors, 603 bellows, 604 shells, 605 back-moving springs, 606 push rods, 607 low-boiling point liquids.
Detailed description of the invention
As shown in Figure 1, the automatic over-temperature protection of solar water heater of embodiment, comprise shutter 2 and temperature control drive unit 6, be equiped with shutter 2 on thermal-collecting tube of solar water heater 3, the control end of shutter 2 is connected by connecting rod 5 with the drive end of a temperature control drive unit 6.
As shown in Figure 2, described temperature control drive unit 6 is made up of expansion of liquids pipe 601, tube connector 602, bellows 603, back-moving spring 605, push rod 606 and shell 604.
Expansion of liquids pipe 601 is welded into airtight integrated container by tube connector 602 and bellows 603, can according to the convenient bending of the needs of installation site when tube connector 602 effect is to install, also can, without tube connector 602, directly need expansion of liquids pipe 601 and bellows 603 to be welded into airtight integrated container according to shape during concrete production.
Poured into low-boiling point liquid 607 inside above-mentioned airtight integrated container, namely boiling point is lower than the liquid of 80 DEG C, as methyl alcohol, ethanol etc.Be welded in airtight integrated container at expansion of liquids pipe and bellows after perfusion, gas, liquid proportional are between 1:1---2:1.
Bellows 603 is connected with the drive end that push rod 606 is temperature control drive unit 6.Back-moving spring 605 contacts between shell 604 and bellows 603, in order to reset to bellows 603.
As shown in Figure 1, on the tank outer wall that temperature control drive unit 6 is fixedly mounted on solar water heater or support, wherein expansion of liquids pipe 601 is plugged in water tank 1 mounting structure.
See Fig. 3, when water temperature rises to 78 DEG C, ethanol evaporating, volumetric expansion, bellows 603 is extended, and push rod 606 ejects.
This process finally promotes shutter and closes, and blocks thermal-collecting tube, prevents from continuing to absorb heat.
See Fig. 2, cool when water on water heater or through evening, Water in Water Tanks temperature drop is low, and lower than 78 degrees Celsius, alcohol vapour cooling liquid, volume reduces, and bellows 603 is shunk under the effect of back-moving spring 605, push rod 606 indentation.
This process finally pulls shutter to open, and thermal-collecting tube enters heat absorption duty.
The utility model make use of the vaporization of liquid, and whole temperature control drive unit adopts the structure of closed container, has high reliability and long-life advantage.
