Description
Technical field
The present invention relates to a kind of expansion bellow, particularly the special expansion bellow of a kind of solar energy heat collection pipe.
Background technology
At present, in the expansion joint that existing solar energy heat collection pipe is special, pipe thermal expansion is free state, and contacting with end flanges under gravity makes original air heat-insulation layer lose efficacy.Solar energy heat collection pipe band special of the prior art slides the expansion bellow of heat insulation guide function, comprise bellows and the interior pipe that slides, bellows fixed cover is pipe periphery in described slip, the expansion bellow of this structure only uses bolt to fix in the end of bellows, heat is delivered to kovar alloy sealing-in from interior pipe and easily causes vacuum layer between inner and outer pipes to destroy, thus, cause tubular heat in solar energy heat collection pipe to be delivered to flange, reduce product result of use.
Summary of the invention
The object of the invention is, in order to overcome above deficiency, to provide a kind of solar energy heat collection pipe special expansion bellow.
Object of the present invention realizes like this:
The special expansion bellow of a kind of solar energy heat collection pipe of the present invention, comprise bellows and the interior pipe that slides, bellows fixed cover is pipe periphery in described slip, and wherein, inside, described bellows two ends is provided with clamping body, described bellows is connected and fixed by clamping body the interior pipe that slides, described clamping body comprises multiple fixing bayonet socket, and described fixing bayonet socket quantity is 3-9, and described fixing bayonet socket is positioned at bellows interior two ends, it is identical that bayonet socket quantity is fixed at described two ends, and described fixing bayonet socket is in being evenly distributed; Described fixing bayonet socket is integral type structure, comprises the first flanging, the second flanging and the 3rd flanging; Described first flanging and the second flanging angle α are 90 degree, and described second flanging and the 3rd flanging angle β are 90 degree, and length L1, the second flanging length L2 of described first flanging and the ratio of the 3rd flanging length L3 are 9:4:1.
The special expansion bellow of above-mentioned a kind of solar energy heat collection pipe, wherein, preferably, the quantity of described fixing bayonet socket 3 is 8.
Compared with prior art, beneficial effect of the present invention is: arrange clamping body at bellows two ends, accomplishes that effectively clamping is managed in sliding, and makes heat not easily run off, improves product result of use.Clamping body is made up of multiple fixing bayonet socket, improves clamping effect.Through repeatedly science measuring and calculating, when length L1, the second flanging length L2 of the first flanging and the ratio of the 3rd flanging length L3 are 9:4:1, the clamping best results of fixing bayonet socket.
Accompanying drawing explanation
Fig. 1 is side schematic view of the present invention.
Fig. 2 is that bellows interior of the present invention fixes bayonet socket sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, the special expansion bellow of a kind of solar energy heat collection pipe of the present invention, comprise bellows 1 and the interior pipe 4 that slides, bellows 1 fixed cover is pipe 4 periphery in described slip, wherein, inside, described bellows 1 two ends is provided with clamping body 2, described bellows 2 is connected and fixed by clamping body 3 the interior pipe 4 that slides, described clamping body 2 comprises multiple fixing bayonet socket 3, described fixing bayonet socket 3 quantity is 3-9, described fixing bayonet socket 3 is positioned at the inner two ends of bellows 1, and it is identical that bayonet socket 3 quantity is fixed at described two ends, and described fixing bayonet socket 3 is in being evenly distributed; Described fixing bayonet socket 3 is integral type structure, comprises the first flanging 31, second flanging 32 and the 3rd flanging 33; Described first flanging 31 and the second flanging 32 angle α are 90 degree, and described second flanging 32 and the 3rd flanging 33 angle β are 90 degree, and length L1, the second flanging 32 length L2 of described first flanging 31 and the ratio of the 3rd flanging 33 length L3 are 9:4:1.
The special expansion bellow of above-mentioned a kind of solar energy heat collection pipe, wherein, preferably, the quantity of described fixing bayonet socket is 8.
Compared with prior art, beneficial effect of the present invention is: arrange clamping body at bellows two ends, accomplishes that effectively clamping is managed in sliding, and makes heat not easily run off, improves product result of use.Clamping body is made up of multiple fixing bayonet socket, improves clamping effect.Through repeatedly science measuring and calculating, when length L1, the second flanging length L2 of the first flanging and the ratio of the 3rd flanging length L3 are 9:4:1, the clamping best results of fixing bayonet socket.
Above embodiment is only used to further illustrate the present invention; can not be interpreted as limiting the scope of the invention, some nonessential improvement that those skilled in the art's foregoing according to the present invention is made and adjustment all belong to protection scope of the present invention.
