Abstract
The utility model relates to a large-caliber corrugated pipe consisting of a spiral-spring pipe framework and the large-caliber corrugated pipe can effectively improve the strength of the large-caliber corrugated pipe and fundamentally improve elasticity of the large-caliber corrugated pipe and comprises an inner pipe. A spiral-spring pipe is combined on the inner pipe, an inner wall of the spiral-spring pipe is adhesively fit with an outer wall of the inner pipe, and a plastic layer is arranged on the surface of the spiral-spring pipe. The large-caliber corrugated pipe has the advantages that the integral compressive and bearing strength of the corrugated pipe is greatly improved, stretching change of the corrugated pipe caused by temperature is restricted to the maximum extent, and adaptability of the corrugated pipe to different temperatures is further improved, so that disconnection and fluid leakage of a butt joint of the corrugated pipe are avoided.
Description
Technical field
The utility model relates to a kind ofly can not only improve heavy caliber bellows intensity effectively, and can make the elasticity of heavy caliber bellows obtain a kind of heavy caliber bellows that is made up of the snake-spring tube skeleton that essence improves, and belongs to bellows and makes the field.
Background technique
CN201078525Y, title " socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe ", it is used to solve the problem of easy seepage of steel band reinforced polyethylene spiral ripple pipe connection interface and poor reliability.Socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe; Be the metal frame that twines to be fixed on the inner layer polyethylene with outer layer polyethylene; Particularly an end of bellows is provided with socket, and the other end of bellows is provided with bellmouth, imbeds a circle electric heating element on the bellmouth inwall and forms.Adopt this socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe, can be widely used in the connection construction of plastic tube.Its deficiency: the one, metal frame is the outer structure of taking off, and what form with inner layer polyethylene is that the line face contact, rather than face contacts; Not only plyability is poor; And under the effect of external force, metal frame is prone to take off mobile outward, causes inner layer polyethylene is destroyed; The quality of direct shadow pipe matter, even cause inner layer polyethylene damaged; The 2nd, support strength is low, because metal frame is the outer structure of taking off, outwards move its metal frame both sides of external pressure, not only causes the layering of metal frame and inner layer polyethylene, and cause the direct reduction of inner layer polyethylene intensity; The 3rd, because outer layer polyethylene and metal frame are two kinds of material different, had nothing in common with each other by its coefficient that expands with heat and contract with cold of Influence of Temperature, therefore stratification in use takes place inevitably, cause bellows intensity sharply to descend, bellows caves in.
The model utility content
Purpose of design: avoid the deficiency in the background technique, design a kind of heavy caliber bellows that can not only improve effectively and strengthen, and can make the elasticity of heavy caliber bellows obtain a kind of heavy caliber bellows that constitutes by the snake-spring tube skeleton that essence improves.
Design proposal: in order to realize above-mentioned purpose of design.Snake-spring tube on inner pipe compound and snake-spring tube inwall and the bonding design that cooperates of outer wall of inner tube are the major technique characteristics of the utility model.The purpose of doing like this is: the circle muscle that constitutes snake-spring tube is just as stiffening rib; When itself and interior pipe melting adhered compound after; Bearing strength and bearing strength in not only can greatly improving in the pipe pipe; And improved the entire compression intensity of bellows, the more important thing is that a plurality of protruding circle muscle that constitute snake-spring tube have played the variation of mutual restriction plastic inner pipe coefficient of dilatation, make bellows can adapt to the different fluid temperature variation better; Thereby avoided the bellows temperature influence effectively, its extending amount causes the bellows joint to be thrown off and fluid runs the appearance of leaking phenomenon.
Technological scheme: a kind of heavy caliber bellows that constitutes by the snake-spring tube skeleton, it comprises interior pipe, the on inner pipe compound and snake-spring tube inwall of snake-spring tube cooperates with outer wall of inner tube is bonding, is equipped with plastic layer on the snake-spring tube face.
The utility model is compared with background technique; Entire compression, the bearing strength of bellows have not only greatly been improved; And retrained temperature to greatest extent the extending amount that bellows caused has been changed; Make bellows obtain further raising, thereby avoided the generation that the bellows joint is thrown off, fluid runs the leakage phenomenon the adaptability of different temperatures.
Description of drawings
Fig. 1 is the cross section structure schematic representation of the multiple plastic layer of pipe inside and outside wall.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of heavy caliber bellows that is made up of the snake-spring tube skeleton, pipe 1 in it comprises on the pipe 1 and snake-spring tube 2 inwalls and interior bonding cooperation of pipe 1 outer wall, is equipped with plastic layer 3 on 2 of the snake-spring tubes in snake-spring tube 2 is compounded in.2 of said snake-spring tubes are gone up to dash has a plurality of wedges nail hole 4 and wedge nail 4 holes, hole along forming the hole circle.Said snake-spring tube adopts steel band to make or adopts aluminium strip to make.Its making method: twine on the bellows core rod that increases the pipe production line at the heavy caliber polyolefin of claimant's manufacturing the snake-spring tube concentric locking collar and snake-spring tube is spacing with the bellows core rod and cooperates; Adopt the heavy caliber polyolefin of claimant's manufacturing twine to increase the pipe production line in making bellows in the pipe process then; The pipe molten plastic is melting adhered compound with the snake-spring tube inwall in the process of interior pipe melt-shaping in being used in its production line making; Cooling its snake-spring tube of back and outer wall of inner tube are one; Adopt the heavy caliber polyolefin winding growth pipe production line of claimant's manufacturing that molten plastic is compounded on the snake-spring tube outer wall at last, cooling forming gets final product.
What need understand is: the detailed text description though above-mentioned mentality of designing to the utility model is contrasted; But these text descriptions; Just the simple text of the utility model mentality of designing is described, rather than to the restriction of the utility model mentality of designing, any combination that does not exceed the utility model mentality of designing; Increase and modification, all fall in the protection domain of the utility model.
Claims (2)
1. a heavy caliber bellows that is made up of the snake-spring tube skeleton is managed ⑴ in it comprises, it is characterized in that: pipe ⑴ went up and snake-spring tube ⑵ inwall and interior bonding cooperation of pipe ⑴ outer wall in snake-spring tube ⑵ was compounded in, and was equipped with plastic layer ⑶ on the snake-spring tube ⑵ face.
2. the heavy caliber bellows that is made up of the snake-spring tube skeleton according to claim 1 is characterized in that: dashing on the said snake-spring tube ⑵ face has a plurality of wedge nail hole ⑷ and wedge nail ⑷ hole, hole along forming the hole circle.
