Description
Technical field
The utility model relates to body equipment technology field, particularly relates to a kind of high flexibility composite pipe.
Background technique
Current, because various composite pipe has good usability and the feature such as quick and easy for installation, to be widely used in industry, agricultural and life each field as conveyance conduit.Water inlet, waste pipe, electric wire protective tube etc. often adopt composite pipe.In prior art, composite pipe often adopts metal tube and plastic tube to carry out compound, utilizes metal tube to improve good intensity, and utilizes plastic tube to make composite pipe have lower weight.When metal tube is thinner in composite pipe, often make the anti-pressure ability of composite pipe lower, and when metal tube is thicker, then make the bending properties of composite pipe not enough, therefore, the anti-pressure ability of composite pipe and bending properties cannot well be taken into account, and need improve.
Model utility content
In order to solve the technical problem existed in background technique, the utility model proposes a kind of high flexibility composite pipe, its anti-pressure ability is good and bending properties is excellent.
A kind of high flexibility composite pipe that the utility model proposes, plastic inner pipe, reinforcement steel pipe and plastic outer tube, plastic inner pipe, reinforcement steel pipe, plastic outer tube are socketed successively, the tube wall strengthening steel pipe has the stiffening rib of spiral distribution, stiffening rib is protruding to the inner surface of tube wall and outer surface both sides strengthening steel pipe, the summit of homonymy projection is located along the same line and this straight line and composite pipe centerline axis parallel, between plastic inner pipe and reinforcement steel pipe, there is the first heat-fusing glue layer, strengthen, between steel pipe and plastic outer tube, there is the second heat-fusing glue layer; With composite pipe length direction for X-axis, with the radial direction of composite pipe for Y-axis, between the adjacent homonymy convex apexes of stiffening rib, line is take y as dependent variable, and x is the quadratic function of independent variable, and wherein, plastic inner pipe and plastic outer tube all adopt crosslinked polyethylene to make.
Preferably, the spacing between the adjacent homonymy convex apexes of stiffening rib and the external diameter ratio of plastic outer tube are 0.05-0.3.
Preferably, the spacing between the adjacent homonymy convex apexes of stiffening rib and the ratio of height of projection are 0.3-0.6.
In above-mentioned high flexibility composite pipe, the plastic inner pipe being positioned at internal layer can make composite pipe inwall have smooth surface, thus when for Liquid transfer, there is less flow resistance, being positioned at outer field plastic outer tube can make composite pipe have good anti-extrusion ability, the tube wall of reinforcement steel pipe will be arranged the stiffening rib with spiral distribution, can make to strengthen steel pipe provides on good intensity basis for composite pipe, there is good pliability, simultaneously, because plastic inner pipe and plastic outer tube all adopt crosslinked polyethylene to make, composite pipe can be made to obtain on good anti-pressure ability basis, crooking ability is strong, reinforcing rib structure is designed to composite pipe length direction as X-axis, with the radial direction of composite pipe for Y-axis, between the adjacent homonymy convex apexes of stiffening rib, line is take y as dependent variable, and x is the quadratic function of independent variable, can ensure that stiffening rib obtains good bending properties and mechanical strength, have the first heat-fusing glue layer between plastic inner pipe and reinforcement steel pipe, the combination strengthen having the second heat-fusing glue layer between steel pipe and plastic outer tube, make plastic inner pipe, strengthened between steel pipe, plastic outer tube is good, not easily produces slip, departs from.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high flexibility composite pipe that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of high flexibility composite pipe that the utility model proposes.
With reference to Fig. 1, in one embodiment, a kind of high flexibility composite pipe that the utility model proposes, plastic inner pipe 1, strengthen steel pipe 2 and plastic outer tube 3, plastic inner pipe 1, strengthen steel pipe 2, plastic outer tube 3 is socketed successively, the tube wall strengthening steel pipe 2 has the stiffening rib of spiral distribution, stiffening rib is protruding to the inner surface of tube wall and outer surface both sides strengthening steel pipe 2, the summit of homonymy projection is located along the same line and this straight line and composite pipe centerline axis parallel, between plastic inner pipe 1 and reinforcement steel pipe 2, there is the first heat-fusing glue layer 4, strengthen, between steel pipe 2 and plastic outer tube 3, there is the second heat-fusing glue layer 5, with composite pipe length direction for X-axis, with the radial direction of composite pipe for Y-axis, between the adjacent homonymy convex apexes of stiffening rib, line is take y as dependent variable, and x is the quadratic function of independent variable, and wherein, plastic inner pipe 1 and plastic outer tube 3 all adopt crosslinked polyethylene to make.
In the above-described embodiments, the plastic inner pipe 1 being positioned at internal layer can make composite pipe inwall have smooth surface, thus when for Liquid transfer, there is less flow resistance, being positioned at outer field plastic outer tube 3 can make composite pipe have good anti-extrusion ability, the tube wall of reinforcement steel pipe 2 will be arranged the stiffening rib with spiral distribution, can make to strengthen steel pipe 2 provides on good intensity basis for composite pipe, there is good pliability, simultaneously, because plastic inner pipe 1 and plastic outer tube 3 all adopt crosslinked polyethylene to make, composite pipe can be made to obtain on good anti-pressure ability basis, crooking ability is strong, reinforcing rib structure is designed to composite pipe length direction as X-axis, with the radial direction of composite pipe for Y-axis, between the adjacent homonymy convex apexes of stiffening rib, line is take y as dependent variable, and x is the quadratic function of independent variable, can ensure that stiffening rib obtains good bending properties and mechanical strength, have the first heat-fusing glue layer 4 between plastic inner pipe 1 and reinforcement steel pipe 2, the combination strengthen having the second heat-fusing glue layer 5 between steel pipe 2 and plastic outer tube 3, make plastic inner pipe 1, strengthened between steel pipe 2, plastic outer tube 3 is good, not easily produces slip, departs from.
