Abstract

The utility model relates to a whole-glass vacuum tube solar-energy thermal collecting header with the functions of tube-blasting proof and water-leaking proof, consisting of a header external sheath (1), a header insulating layer (2) and an inner container (7). The two sides of the header are provided with a through hole (9) on which a whole-glass vacuum tube can be arranged; and the through hole (9) is internally provided with a rubber sealing ring (10). A cold water pipe (8) is inserted into the inner container of the header from the back of the header, and is pasted with the inner wall of the inner container (7) of the header and stretches from the top to the bottom; a hot water pipe (5) is penetrated through the back of the head from the upper part of the header to stretch to the outside. In addition, the roof of the header is provided with a floating ball switch (3) capable of sensing the water level; the floating ball switch (3) is connected with a solenoid valve or an acoustooptical alarming device by a signal wire (4), thus sensing and cutting off the water-leaking of the collector, and eliminating the precipitating factor that the vacuum tube blasts because of hot and cold shock; and the outdoor exposing length of a return pipeline is shortened, thus improving the operating safety performance of the collector, decreasing the outdoor heat radiation and stopping the waste of the water resource.

Description

Whole glass vacuum tube solar energy with anti-bombing, leakage proof function can the thermal-arrest header

Technical field

The utility model relates to a kind of full glass vacuum tube solar water system, and particularly a kind of whole glass vacuum tube solar energy with anti-bombing, leakage proof function can the thermal-arrest header.

Background technology

Produce hot water with solar energy, because of significantly environmental protection and economic benefit obtain more and more widely application in industrial and agricultural production and people's lives.In various solar energy heat-collecting devices, glass vacuum pipe heat collector more is regarded as solving the desirable heat collecting element of cold district at annual applied solar energy with its super heat-insulating property.But, glassware because of a variety of causes be easy to cracked characteristics also for this reason the application of class heat collector buried hidden danger.For example vacuum tube is in operation, under high-temperature situation, and the temperature shock of the cold water that the mouth of pipe is burst upon, different parts is uneven in temperature, and internal stress increases suddenly and causes that vacuum tube is cracked.After cracked, intrasystem water can overflow in a large number from rent, has both caused the waste of water resource, might derive secondary infringement (as the personal injury to building interior and exterior finishes and even passerby) again.In a single day eliminate the cracked inducement of vacuum tube as much as possible, or can turn off the water source rapidly after cracked, be to improve security of operation, reduces the strong behave of accidental loss.

Summary of the invention

The purpose of this utility model just is to provide a kind of whole glass vacuum tube solar energy energy thermal-arrest header with anti-bombing, leakage proof function, carry out brand-new design by thermal-arrest header to all-glass vacuum tube, make it have the thermal shock of preventing and break after the function of in time cutting off the water supply, can be reduced to Min. to loss.

Whole glass vacuum tube solar energy with anti-bombing, leakage proof function of the present utility model can be made of header crust, header heat-insulation layer and inner bag by the thermal-arrest header, the header both sides offer the through hole that all-glass vacuum tube can be installed, rubber seal is installed in the through hole, cold water pipe enters the header inner bag from the header back side, and pasting the inner bag inwall extend to from the top down the bottom, hot-water line passes the header back side from header top hot water is discharged.The utility model has been done the cold water pipe trend to rearrange, and cold water pipe is placed on the wall of inner container, extends from the top down, and the bottom is provided with outlet.Thereby, when having cold water to burst upon, will pass through the heat effect of cold water pipe tube wall earlier, make the water that flows out the cold water pipe mouth of pipe obtain preheating, thereby reduced the cold and hot temperature difference, alleviated the temperature shock that the all-glass vacuum tube mouth of pipe is subjected to effectively, the cracked inducement of this type of glass tube with vacuum just can be got rid of substantially.

And, the whole glass vacuum tube solar energy with anti-bombing, leakage proof function of the present utility model can the thermal-arrest header on the header end face, have installed can the perception water level float switch.Thereby, when breaking because of a variety of causes all-glass vacuum tube body and produce routed the leakage, because of water level in the header descends, float switch just can send connection (or shutoff) signal, outwards output to corresponding solenoid valve or acoustic-optic alarm by holding wire, just can automatic or manually take countermeasure.

And, whole glass vacuum tube solar energy with anti-bombing, leakage proof function of the present utility model can all make cold water pipe and hot-water line pass the back side of thermal-arrest header by the thermal-arrest header, when the thermal-arrest header is pasted the wall installation, can effectively reduce the water pipe length of exposure, favourable antifreeze.

The specific embodiment

Hereinafter the technical solution of the utility model is introduced with reference to Fig. 1.

Fig. 1 is the view that shows the structure of the whole glass vacuum tube solar energy energy thermal-arrest header with anti-bombing, leakage proof function.The solar energy heating header is made of header crust 1, header heat-insulation layer 2 and inner bag 7, the header both sides offer the through hole 9 that all-glass vacuum tube can be installed, rubber seal 10 is installed in the through hole 9, cold water pipe 8 enters the header inner bag from the header back side, and the inwall that is pasting inner bag 7 extend to from the top down the bottom, hot-water line passes the header back side from header top hot water is discharged.When operation, cold water enters in the cold water pipe 8 from cold water pipe import 6, and flows from the top down in cold water pipe 8, in the bottom flows into the thermal-arrest header.Cold water is preheated when flowing in cold water pipe 8.

On the end face of header, be provided with one can the perception water level float switch 3, holding wire 4 one ends link to each other with float switch 3, the other end links to each other with magnetic valve or acoustic-optic alarm not shown in the figures.Under the full situation of water, float switch 3 is connected (or shutoff) in the thermal-arrest header.When cause the vacuum glass tube to break because of a variety of causes, and when leaking in a large number, water level descends in the thermal-arrest header, float switch 3 turn-offs (or connection), signal is outputed to magnetic valve or acoustic-optic alarm from holding wire 4, thereby, cut off servo entering water electromagnetic valve automatically, or remind the related personnel to cut off the water supply.
