Description
Technical field
The invention belongs to solar energy heating utilization technical field, relate to the protective device after solar vacuum heat-collecting pipe damage, be specifically related to a kind of vacuum heat collection pipe and damage limit leakage device, be specially adapted to the hot water leak limiting solar water heater after vacuum heat collection pipe damages.
Background technology
Solar energy is inexhaustible as a kind of emerging clean energy resource.Making full use of solar energy is a technology meeting China's strategy of sustainable development.Present stage at home market solar low-temperature utilize more and more universal, also more and more obtain consumer, the accreditation of national government and attention.Solar water heater mainly contains flat plate collector and union pipe heat collector, and two kinds of heat collectors are all very ripe technically, and the vacuum pipe heat-collecting pipe used in union pipe heat collector is especially at the development and apply widely that China obtains.
Vacuum heat collection pipe is divided into " full glass " and " glass and metal structure " two large class, change solar energy into heat energy, by the heat-transfer working medium (as water) in union pipe or first carry out heat exchange by vacuum heat collection pipe and heat-transfer working medium heat energy is transported to thermal storage water tank.The core parts of solar water heater are glass heat-collecting vacuum tubes, and it have employed vacuum interlayer, eliminate convection current and the conductive heat loss of gas, and incorporating selectively absorber coatings, the radiation heat loss of vacuum heat collection pipe is dropped to minimum.The inner flask that all-glass vacuum tube thermal-collecting tube elongates as one, be made up of two coaxial circles glass tubes, high vacuum is pumped between inner and outer tubes, the outer surface that selective sunshine absorber coatings (surface, film system) is deposited on interior pipe forms absorber, solar energy is converted to heat energy, the heat-transfer fluid in heating in pipe.
Current domestic solar water heater domestic market general layout is because the factors such as the feature of product and price are formed, and can predict in domestic solar water heater, will be all-glass vacuum tube water heater is main in low-end market.
Due to the direct heat hot water of vacuum heat collection pipe, quick heating, the water capacity in header is easily evaporated or pipe-line system is unreasonable or control system fault time occur that the water in vacuum heat collection pipe reduces, vacuum heat collection pipe top is in air drying.The upper and lower temperature difference of empty set inside heat pipe of taking seriously exceedes the glass tolerance temperature difference when impacting the limit, and the interior pipe of vacuum heat collection pipe can burst, and causes solar heat device to leak, and wherein reason is generally that stress is concentrated, glass has micro-crack to cause being swashed fried.
In sum, how to solve all-glass vacuum tube thermal-collecting tube in solar water heater damage after limit leak problem, to guarantee the normal operation of solar water heater, be one of problem of jointly paying close attention to of those skilled in the art.
Summary of the invention
Leakage problem existing after damaging for the vacuum pipe heat-collecting pipe in above-mentioned solar water heater, the object of the invention is to, and provides the vacuum heat collection pipe that a kind of structure is simple, convenient for production, anti-leak result is good to damage limit leakage device.
In order to realize above-mentioned task, the present invention adopts following technical solution:
A kind of damage limit leakage device of vacuum pipe heat-collecting pipe, comprise vacuum pipe heat-collecting pipe, it is characterized in that, ring-type valve seat is had inside the outer mouth of pipe of vacuum pipe heat-collecting pipe, ring-type valve seat is provided with control flap, control flap is filled in being connected with by stainless steel filament the porous hollow sphere of sponge, and described stainless steel filament length is longer than the length of vacuum pipe heat-collecting pipe.
Vacuum pipe heat-collecting pipe is when normally working, control flap upwarps at ring-type valve seat upper under elastic force effect, open control flap turns over, the selective sunshine absorber coatings (surface, film system) being now deposited on inner tube outer surface forms absorber, and solar energy is converted to heat energy.After water heat absorption in vacuum heat collection pipe, temperature raises, and proportion reduces and rises, and forms a power upwards, forms a thermosiphon system.Along with hot water continuous on move and be stored in the top of storage tank, by convection action, water larger compared with low-density for temperature is delivered to the bottom of vacuum heat collection pipe simultaneously, so move in circles, final whole box water is all increased to certain temperature, and whole solar water heater normally works.
When vacuum heat collection pipe is damaged, the porous hollow sphere filling sponge flows out with current, and under gravity, the porous hollow sphere filling sponge turns over to drop on annular valve under the drive of stainless steel filament closes current.Thus solve because single or multiple vacuum pipe heat-collecting pipe damages, and cause leaking, thus make the problem of solar water heater cisco unity malfunction.
Vacuum pipe heat-collecting pipe of the present invention damages limit leakage device, and the technique effect brought is:
One, solve because vacuum heat collection pipe damages, cause the problem of hot water leak
The porous hollow sphere (plastics, stainless steel) of sponge is filled in be connected with control flap by stainless steel filament one, when vacuum heat collection pipe is damaged, the porous hollow sphere filling sponge flows out with current, under gravity, is turned over by control flap and drops on ring-type valve seat shangguan and close current.Even if thus solution is because of the damage of single or several vacuum heat collection pipes, and the problem causing solar water heater to leak.
Two, structure is simple and easy to install
The primary structure that vacuum pipe heat-collecting pipe of the present invention damages limit leakage device is: have ring-type valve seat (plastics) inside the outer mouth of pipe of vacuum pipe heat-collecting pipe, ring-type valve seat is provided with and controls flap (plastics), control flap is filled in being connected with by stainless steel filament the porous hollow sphere of sponge, it is simple for production, and is easy to be installed in vacuum pipe heat-collecting pipe.
Three, cost is lower, and after vacuum heat collection pipe damages, solar water heater can work on
Structure is simple, with low cost.When damaging due to single or multiple vacuum pipe heat-collecting pipe, and causing solar water heater to leak, during cisco unity malfunction, the vacuum heat collection pipe of damage must be changed.Adopt this device can not allow in the time, or when temporarily not having to supply the vacuum pipe heat-collecting pipe replaced, still can ensure the normal operation of solar water heater, ensure normally carrying out of people's live and work.
