Abstract
The utility model relates to a metal-frame-reinforced composite plastic pipe joint of which the pipe wall is provided with a ring-shaped reinforcing rib. The utility model is characterized in that a metal frame reinforced body which is covered by plastic and has a shape similar to the shape of the pipe joint is arranged in a pipe wall, and the periphery of the pipe wall is provided with a ring-shaped and /or arc-shaped reinforcing convex rib. The pipe joint can bear the high working pressure of fluid in a pipe, and saves raw materials and reduces the cost because of the adoption of the pipe with a thin wall. Because the periphery of the pipe is provided with the reinforcing rib, the rigidity of the pipe is increased, and the pressure bearing capacity of an outer wall is increased. The utility model enlarges the application scope of metal-frame-reinforced composite plastic pipes, especially pipes with large pipe diameters.
Description
The utility model relates to a kind of pipe joint, particularly be a kind of metallic skeleton reinforced composite plastic pipe joint of tube wall band shape stiffening rib.
Existing metallic skeleton reinforced composite plastic pipe joint is because make to strengthen body with metal frame, in the joint for plastic tube wall, coated, the interior bearing capacity of pipe joint is improved, and fluid delivery operation pressure can improve, and bursting pressure improves a lot with the joint for plastic tube of equal thickness of pipe wall.Thereby can reduce the plastic tube wall thickness of this multiunit tube joint and saved a large amount of raw materials for plastics production, make the pipework cost be declined to become low, corrosion-resistant, the competitive multiple tube of a kind of cost.This multiunit tube joint has been saved a large amount of plastic materialss, still can bear higher bursting pressure, but because a large amount of attenuates of wall thickness.And this multiunit tube joint that makes big caliber scarce capacity of bearing capacity in engineering is used because outside the tube wall, make be embedded in underground pipeline, pipe fitting be subjected to ground heavy-duty vehicle and other repeatedly to ground execute weight some factors influence and be out of shape, the crack appears in the joint, escape of liquid occurs, greatly reduce the advantage of this multiple tube.
In view of above reason, the purpose of this utility model is for bearing capacity height in a kind of pipe that can keep multiple tube is provided, tube wall is thin to save material and obvious advantage that cost is low, the pipeline that can overcome big caliber again connects not firm shortcoming bearing capacity height, cost metallic skeleton reinforced composite plastic pipe joint low, indeformable tube wall band shape stiffening rib under heavy burden in the underground not enough and not enough distortion of outer wall bearing capacity because of rigidity of heavy burden.
The purpose of this utility model is achieved like this:
Have in the metallic skeleton reinforced composite plastic pipe joint tube wall of the utility model tube wall band shape stiffening rib by the pertusate metal frame similar of plastic overmold and strengthen body to the pipe joint shape, in the tube wall periphery reinforcement convex tendon of ring-type and/or arcuation is arranged, there is resistance heater the tube wall inboard.
It is entity that above-mentioned pipe joint is strengthened convex tendon.
It is hollow that above-mentioned pipe joint is strengthened convex tendon.
It is rectangle or trapezoidal or the triangle or the circular arc of corner angle rounding off that above-mentioned pipe joint is strengthened the convex tendon sectional shape, connects as one with tube wall.
It is that the sheet metal in hole with holes rolls and is welded that the metal frame of above-mentioned pipe joint increases body.
The metal frame enhancing body of above-mentioned pipe joint is broadwise metal strand and the winding of warp-wise metal strand spiral or is welded.
It is the metal frame that has annular or arc convex tendon of precision casting that above-mentioned pipe joint metal frame strengthens body.
The positive and negative electrode wiring terminal of above-mentioned resistance heater is fixed on the same end of tube wall and is connected with resistance wire (referring to Fig. 1, Fig. 3～Fig. 6) with axial or radial manner.Overcome when caliber is big, the line transportation strong corrosive medium, above-mentioned resistance wire distributes and connector connecting method just has serious problems to occur: behind the resistance wire hot melt connecting tube that inner tube wall distributes is to expose in the corrupt liquid medium, after the deep-etching can in the distribution of inner tube wall bigger hole be appearred along resistance wire, caliber is big, heating power is bigger, and the hole of the resistance silk thread thicker appearance in footpath is bigger, the shortcoming that can cause pipe leakage and pipeline to lose efficacy like this.
The positive and negative electrode wiring terminal of above-mentioned resistance heater is separately fixed at the tube wall two ends and is connected with resistance wire with axial or radial manner, when caliber hour, the line transportation medium is not the deep-etching fluid, it is to run through inwall that resistance wire distributes in tube wall, the positive and negative electrode wiring terminal connects resistance wire respectively at the pipe joint two ends, wiring terminal can be axial connection (referring to Fig. 3) on tube wall, also can be radially to connect (referring to Fig. 5).
Above-mentioned pipe joint jointing has conical cavity, conical surface is equipped with resistance heater (referring to Fig. 4, Fig. 6), pipeline is connected with pipe joint electric heating is molten, the technology gap is also big when caliber is big, and electric heating melts and only depends on the technology gap to cannot say for sure that card connects tight and intensity when connecting, and the utility model is designed to taper at pipe joint jointing inner chamber for this reason, electric heating melts when connecting, can utilize taper that pipe joint and pipeline are axially passed mutually, further eliminate matching gap, form more reliable connection.
Above-mentioned pipe joint jointing has joint socket, and the joint socket internal surface is equipped with resistance heater, and (referring to Fig. 4) coincide, reduces resistance with internal diameter of the pipeline, helps the conveying of powdery, particle media.
The utility model pipe joint can bear higher tube fluid working pressure, reduced cost because of adopting thin walled tube to save raw material again, also because the pipe periphery has stiffening rib to increase the rigidity of pipe and has increased the outer wall bearing capacity, enlarged metallic skeleton reinforced composite plastic pipe, particularly the application area of big-diameter pipeline.
