Abstract
The utility model relates to a coil pipe with a smooth inner wall. The coil pipe is characterized by comprising an inner pipe and at least one plastic pipe, wherein the inner wall surface of the inner pipe is a smooth surface; and the plastic pipes are spirally coiled and adhered to the outer wall surface of the inner pipe along the axial direction of the inner pipe. The utility model has the advantages that: the coil pipe has a simple structure, is convenient to mount and strong in tensile strength, can bear loads both outside and inside the pipe, and is difficultly ruptured to cause leakage.
Description
Technical field
The utility model relates to a kind of structured wall plastic pipe, the smooth smooth no seam of particularly a kind of inwall, and outer wall twines the plastic tube that strengthens.
Background technique
At present, a kind of hollow wall entwining tube being arranged on the market, mainly be used for the draining blowdown, is a kind of no pressure piping, mainly bears from the outside load of tubing.Its advantage is that diameter can be accomplished very big (maximum diameter reaches 3 meters), produces less with raw material, the ring stiffness height, equipment cost is low; Its shortcoming is the inwall out-of-flatness, and the seam that is intertwined and connected is very long, and intensity and sealability are bad, have weak link, and the axial tensile strength of tubing is lower, easy seepage in the using process.Also have a kind of plastics solid wall pipe in addition on the market, wall thickness is thicker can be used for water delivery, defeated combustion gas etc., is a kind of pressure piping that has, and can bear the outside load of tubing and also can bear inner load; Its shortcoming is that wall thickness is very thick, and wall thickness do not allow to be easy to do evenly, waste material, and heavy caliber (diameter surpasses more than 800) processing difficulties, equipment cost is very high.
The model utility content
The utility model is exactly the advantage that has combined above two kinds of tubing, overcomes and avoids above-mentioned shortcoming, provides a kind of inwall smooth smooth; Inwall does not have seam; The tensile strength height that tubing is axial, non-leakage in the using process, the outer interior planomural entwining tube that twines enhancing at least by a plastic tube.
The technological scheme of the utility model is achieved in that a kind of interior planomural entwining tube; It is characterized in that: pipe and at least one plastic tube in comprising; Should interior internal face of managing be smooth surface; This plastic tube adopts minimum material to obtain maximum intensity along on the outer wall of interior tubular axis pipe in winding is bonded in a spiral manner to reach.
Preferably, the bonding mode of employing that is connected of said interior pipe and plastic tube.Bond can be special-purpose Bond, also can adopt adhesive property good in low-density plastics.
Preferably, the two ends of said interior pipe are formed with the hot melting connector that supplies butt joint, the external diameter of managing in the external diameter of this hot melting connector is slightly larger than, and its internal diameter is identical with the internal diameter of interior pipe; Or the external diameter of this hot melting connector also can be identical with the external diameter of interior pipe, but the internal diameter that its internal diameter is managed in being slightly less than.Pipe adopts hot melting mode to dock in two, has intensity height, the convenient to operation and advantage that is not easy to leak.
Preferably, the cross section of said plastic tube is triangle, trapezoidal, square, circular, circular arc or door leaf type or other approximate shapes, increases the structural strength of plastic tube effectively, improves the ability of the anti-external load of entwining tube.
Preferably, leave certain distance between the adjacent plastic tube.Because entwining tube can be applied to various working environments, its working strength requires also to have difference, so, between distance be change unfixed.Concrete parameter confirms that according to requirement of strength requirement of strength is low, and distance is big.
The advantage of the utility model: simple in structure, easy for installation, tensile strength is high, can bear the outside load of tubing, also can bear inner load, simultaneously, has the advantages that to be not easy to leak.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.See also Fig. 1, Fig. 1 is the structural representation of the utility model.A kind of interior planomural entwining tube shown in the figure, 1 and two plastic tube 3 of pipe in comprising, internal face of pipe is a smooth surface in this, this interior tubular axis in plastic tube edge leaves certain distance between two plastic tubes on the outer wall that is intertwined and connected in a spiral manner at interior pipe.Promptly in the processing entwining tube, produce earlier the thin interior pipe 1 of wall thickness (different applications, the wall thickness of interior pipe 1 can adopt different thickness; Specifically confirm according to actual conditions; Should confirm that mode is an existing technology, repeated no more at this) because interior pipe is a thin walled tube; So the difficult forming in the time of can avoiding producing the heavy wall solid wall pipe of heavy caliber (diameter surpasses more than 800), the shortcoming that wall thickness deviation is big.And pipe is 1 o'clock in producing, and through the technology adjustment, can process hot melting connector 4 very easily, during installing and using, during the planomural entwining tube, can adopt the mode that hot melt docks to connect like this, and joint strength is high, convenient to operation and be not easy leakage.The planomural entwining tube bears outside load and still bears inner load in no matter letting, and can adopt this kind Placement.Reprocess out the plastic tube 3 of minor diameter; Then plastic tube 3 is twined on the interior pipe 1 that formerly processes; Between interior pipe 1 and plastic tube 3, cement with Bond 2, used Bond 2 can be special-purpose Bond, also can adopt adhesive property good in low-density plastics.According to different intensity usage requirements, can regulate the distance between adjacent two plastic tubes 3, adopt minimum material to obtain maximum intensity to reach, this confirms that mode also for existing technology, repeats no more at this.
See also Fig. 2, Fig. 2 is the schematic cross-section of plastic tube in the utility model.The various forms in the cross section of plastic tube 3 can be other shapes such as triangle, trapezoidal, square, circular arc, increases the structural strength of plastic tube effectively, improves the ability of the anti-external load of entwining tube.
During use, entwining tube is placed in the industrial environment, and liquid or gas constantly pass through from interior pipe, realizes the purpose of two places transportation.Plastic tube had both born the outside load of tubing, also bore inner load, and pipe in the protection improves its working life widely.
Below only expressed the mode of execution of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
The utility model has the advantages that: the interior planomural entwining tube of different-diameter, wall thickness of pipe is transformable in it, in different applications, the wall thickness of interior pipe can adopt different thickness; According to different requirement of strength, the spacing of the tubule that its skin is used to strengthen also can change, and certainly the section form of tubule can be other shapes such as triangle, trapezoidal, square, circular arc; Because working joint very easily adopts the mode of hot melt butt joint to connect when installing and using, joint strength is high, convenient to operation and be not easy leakage; The utility model can bear the outside load of tubing and also can bear inner load in addition.
