Abstract
The invention discloses a bellow expansion joint special for a solar heat collecting tube. The bellow expansion joint special for the solar heat collecting tube comprises a corrugated tube and a sliding inner tube. A corrugated tube fixing sleeve is arranged on the periphery of the sliding inner tube. The two ends of the corrugated tube are internally provided with clamping mechanisms, and the corrugated tube is connected with and fixes the sliding inner tube through a clamping mechanism. Each clamping mechanism comprises a plurality of fixing bayonets which are 3-9 in number, wherein the fixing bayonets are located at the two ends in the corrugated tube, the number of the fixing bayonets at one end is equal to the number of the fixing bayonets at the other end, and the fixing bayonets are evenly distributed. The fixing bayonets are of an integrated structure, and each fixing bayonet comprises a first folding edge, a second folding edge and a third folding edge. The two ends of the corrugated tube are provided with the clamping mechanisms so that the sliding inner tube can be effectively clamped. Heat is not prone to escaping, and the using effect of products is improved. The clamping mechanisms are composed of the fixing bayonets, and the clamping effect is improved.
Description
Technical field
The present invention relates to a kind of expansion bellow, particularly the special-purpose expansion bellow of a kind of solar energy heat collection pipe.
Background technology
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 flanges.The slide expansion bellow 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 expansion bellow 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 result of use.
Summary of the invention
The object of the invention is in order to overcome above deficiency, provide a kind of solar energy heat collection pipe special-purpose expansion bellow.
Object of the present invention realizes like this:
The special-purpose expansion bellow of a kind of solar energy heat collection pipe of the present invention, comprise bellows and slip inner tube, bellows fixed cover is in described slip inner tube periphery, and wherein, inside, described bellows two ends is provided with clamping body, described bellows is connected and fixed slip inner tube by clamping body, described clamping body 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 special-purpose expansion bellow 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 body is set, accomplishes effectively to clamp slip inner tube, make heat be difficult for running off, improve product result of use.Clamping body 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.
