Abstract
The invention discloses a dedicated bellow expansion joint corrugated pipe for solar collector tubes. Clamping mechanisms are arranged inside the two ends of the corrugated pipe, and each clamping mechanism comprises a plurality of fixing bayonets, wherein the number of the fixing bayonets is 3 to 9, and the fixing bayonets are positioned at the two ends inside the corrugated pipe; the numbers of the fixing bayonets at the two ends are the same, and the fixing bayonets are evenly distributed; the fixing bayonet is of an integrated structure and comprises a first folding edge, a second folding edge and a third folding edge. The clamping mechanisms are arranged at the two ends of the corrugated pipe to effectively clamp an inner sliding tube, so that the heat is not easily lost, and the service effect of a product is improved. The clamping mechanism is formed by a plurality of fixing bayonets, so the clamping effect is improved.
Description
Technical field
The present invention relates to a kind of corrugated expansion joint, particularly the bellows of the special-purpose corrugated expansion joint of a kind of solar energy heat collection pipe.
Background technique
At present, the expansion joint inner tube thermal expansion of existing solar energy heat collection pipe special use is free state, contacts original air heat-insulation layer was lost efficacy under Action of Gravity Field with end flange.The slide corrugated expansion joint of heat insulation guide function of solar energy heat collection pipe band special of the prior art, comprise bellows and slip inner tube, bellows fixed cover is in described slip inner tube periphery, the corrugated expansion joint of this structure is only used bolt to fix in the end of bellows, heat is delivered to kovar alloy sealing-in from inner tube and easily causes vacuum layer between inner and outer pipes to destroy, thereby, cause interior tubular heat in solar energy heat collection pipe to be delivered to flange, reduce product using effect.
Summary of the invention
The object of the invention is in order to overcome above deficiency, the bellows of the special-purpose corrugated expansion joint of a kind of solar energy heat collection pipe is provided.
Object of the present invention realizes like this:
The bellows of the special-purpose corrugated expansion joint of a kind of solar energy heat collection pipe of the present invention, comprise bellows, wherein, inside, described bellows two ends is provided with clamping mechanism, described clamping mechanism comprises a plurality of fixedly bayonet sockets, and described fixedly bayonet socket quantity is 3-9, and described fixedly bayonet socket is positioned at bellows interior two ends, fixedly bayonet socket quantity is identical at described two ends, and described fixedly bayonet socket is and is evenly distributed; Described fixedly bayonet socket is integral type structure, comprises the first flanging, the second flanging and the 3rd flanging; Described the first flanging and the second flanging angle α are 90 degree, and described the second flanging and the 3rd flanging angle β are 90 degree, and the ratio of length L 1, the second flanging length L 2 and the 3rd flanging length L 3 of described the first flanging is 9:4:1.
The bellows of the special-purpose corrugated expansion joint of above-mentioned a kind of solar energy heat collection pipe, wherein, preferably, the quantity of described fixedly bayonet socket 3 is 8.
Compared with prior art, beneficial effect of the present invention is: at bellows two ends, clamping mechanism is set, accomplishes effectively to clamp slip inner tube, make heat be difficult for running off, improve product using effect.Clamping mechanism is comprised of a plurality of fixedly bayonet sockets, improves clamping effect.Through the measuring and calculating of science repeatedly, when the ratio of length L 1, the second flanging length L 2 and the 3rd flanging length L 3 of the first flanging is 9:4:1, the fixing clamping best results of bayonet socket.
Accompanying drawing explanation
Fig. 1 is side schematic view of the present invention.
Fig. 2 is fixedly bayonet socket sectional view of bellows interior of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, the bellows of the special-purpose corrugated expansion joint of a kind of solar energy heat collection pipe of the present invention, comprise bellows 1, wherein, described bellows 1 inside, two ends is provided with clamping mechanism 2, and described clamping mechanism 2 comprises a plurality of fixedly bayonet sockets 3, described fixedly bayonet socket 3 quantity are 3-9, described fixedly bayonet socket 3 is positioned at the inner two ends of bellows 1, and fixedly bayonet socket 3 quantity are identical at described two ends, and described fixedly bayonet socket 3 is and is evenly distributed; Described fixedly bayonet socket 3 is integral type structure, comprises the first flanging 31, the second flanging 32 and the 3rd flanging 33; Described the first flanging 31 and the second flanging 32 angle α are 90 degree, and described the second flanging 32 and the 3rd flanging 33 angle β are 90 degree, and the ratio of length L 1, the second flanging 32 length L 2 and the 3rd flanging 33 length L 3 of described the first flanging 31 is 9:4:1.
The bellows of the special-purpose corrugated expansion joint of above-mentioned a kind of solar energy heat collection pipe, wherein, preferably, the quantity of described fixedly bayonet socket is 8.
Compared with prior art, beneficial effect of the present invention is: at bellows two ends, clamping mechanism is set, accomplishes effectively to clamp slip inner tube, make heat be difficult for running off, improve product using effect.Clamping mechanism is comprised of a plurality of fixedly bayonet sockets, improves clamping effect.Through the measuring and calculating of science repeatedly, when the ratio of length L 1, the second flanging length L 2 and the 3rd flanging length L 3 of the first flanging is 9:4:1, the fixing clamping best results of 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.
