Abstract
The invention relates to a large-caliber corrugated pipe comprising a spiral-spring pipe framework and a manufacturing method, wherein the strength of the large-caliber corrugated pipe can be effectively improved, and elasticity of the large-caliber corrugated pipe can be fundamentally improved. The large-caliber corrugated pipe comprises an inner pipe, a spiral-spring pipe is combined on the inner pipe, the inner wall of the spiral-spring pipe is in adhesive fit with the 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 by means of the design of the hole ring type coil reed pipe framework, 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 present invention 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 and making method that constitutes by the snake-spring tube skeleton that essence improves, belong to bellows and make 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.
Summary of the invention
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 and making method that constitutes by the snake-spring tube skeleton that essence improves.
Design proposal: in order to realize above-mentioned purpose of design.1, on inner pipe compound and snake-spring tube inwall and the bonding design that cooperates of outer wall of inner tube of snake-spring tube is one of technical characteristics of the present invention.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.2, dashing the design that has a plurality of wedges nail hole and wedge nail hole, hole to enclose along the formation hole on the snake-spring tube face, is two of technical characteristics of the present invention.The purpose of doing like this is: when molten plastic and snake-spring tube compound tense; The plastics of its fusion externally effect of pressure get into wedge nail hole formation wedge nail down; This wedge nail firmly is connected as a single entity compound snake-spring tube and interior pipe on inner pipe; And put the molten plastic layer on the snake-spring tube face after the cooling with the snake-spring tube outer wall on a plurality of by combining together along forming the hole circle in wedge nail hole, hole, its hole is enclosed just as the boss stiffening rib, makes the intensity that is compounded in the plastic layer on the snake-spring tube outer wall obtain the raising of essence.
Technological scheme 1: 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.
Technological scheme 2: a kind of making method of the heavy caliber bellows that constitutes by the snake-spring tube skeleton; 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.
The present invention compares with background technique; The design of hole circle formula snake-spring tube skeleton; Entire compression, the bearing strength of bellows have not only greatly been improved; And retrained temperature to greatest extent to the extending amount variation that bellows caused, 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.
