Abstract
The present invention relates to a reinforced pressure-resistant plastic pipe and a pipe joint. The annular rib material of the existing reinforced pressure-resistant plastic pipe is arranged on the outer wall of the pipe or at the middle part of the inner wall. The annular rib material of the present invention is arranged in the part adjacent to the outer wall or the inner wall in the pipe wall of the pipe or the pipe joint; thus, the inertia moment of the pipe and the pipe joint is enhanced. Consequently, the present invention can decrease wall thickness, save materials and reduce cost under the preconditions that the pipe diameters are the same and the same outer rigidity and the internal pressure science performance resistance are satisfied. The reinforced pressure-resistant plastic pipe and the pipe joint adopting the structure of the present invention can save materials by 20 to 40%, and can obtain obvious economic benefits when especially used for plastics pipes with large pipe diameter and pipe joints.
Description
The invention belongs to a kind of plastic tube and pipe connecting member of plastics material, comprise the plastic tube and the tubular union of the fibre reinforced plastic tube material and the tubular union, particularly big caliber of glass fibre reinforced plastics class.
In order to improve the intensity of plastic tube, have in the prior art in the wall of tubing or the scheme of reinforcement on the outer wall, the disclosed technology of ZL93100742.9 is to establish hoop muscle material at the plastic tube outer wall, in order to outer rigidity and the anti-interior pressure energy power that improves tubing, under identical caliber and load performance, reduce wall thickness, save material; The disclosed technology of ZL94209612.6 is to establish netted tubular muscle material skeleton at half position (being intermediate portion in the tube wall) of pipe internal diameter and pipe outer diameter sum, this scheme also helps to improve the mechanical strength of tubing, but they also exist when pipe diameter increases, in order to satisfy outer rigidity and anti-internal pressure requirement, tube wall thickness increases thereupon, the deficiency that cost is higher.
The present invention aim to provide a kind of satisfy identical outside rigidity and anti-under the prerequisite of pressure request, can further reduce the tube wall materials, ribbed pressure-resistant plastic tube that reduces cost and pipe connecting member of plastics material.
The technological scheme that realizes above-mentioned purpose is: the present invention is provided with the hoop muscle that intensity and Young's modulus are significantly higher than the tube wall material in the tubular wall of plastic tube, it is characterized in that this hoop muscle has at least one deck to be provided in a side of to press close to the position of tube wall outer wall or internal face.
Pipe connecting member of plastics material is also adopted scheme same as described above, promptly in the tubular wall of pipe connecting member of plastics material, be provided with the hoop muscle that intensity and Young's modulus are significantly higher than the tube wall material, it is characterized in that this hoop muscle has at least one deck to be provided in a side of to press close to the position of tube wall outer wall or internal face.
The ring muscle can strengthen moment of inertia, for example: to the high-density polyethylene plastics tubing of 10mm wall thickness more the closer to outer wall or internal face, with diameter is that the steel wire of 2mm is when making spirality hoop muscle, if the ring muscle is by the described tube wall intermediate portion that is located at of prior art, during longitudinal pitch 5mm, moment of inertia is 124.4mm
4And if respectively establish one deck spirality hoop muscle at tube wall near the position of outer wall and internal face by one of conception plans of the present invention; longitudinal pitch is 10mm; when (the muscle material keeps the 1mm spacing with outer pipe wall face and internal face separately and makes protective layer), moment of inertia then is 1602.4mm to two-layer hoop muscle radial center apart from 6mm
4Be the former 12.9 times; press performance identical in the two is anti-; the latter's moment of inertia has then improved tens times than the former; improved outer rigidity greatly; so under the condition that can satisfy tubing or tubular union outer wall surface or inner wall surface work ring tendon protective layer, should make as far as possible close outer wall of hoop muscle material or inwall wall in the wall.
The present invention can same caliber, satisfy identical outside under the prerequisite of rigidity and anti-internal pressure performance requirement, further reduce the pipe thickness of tubing or tubular union, obtain the effect of saving materials, reducing cost.During greater than the major diameter plastic tube of 200mm and tubular union, can obtain tangible economic benefit especially for diameter, generally can save tubing materials 20-40%.

Embodiment 1 (referring to Fig. 1)
This example is pressed close to outer wall in tube wall position is provided with spirality hoop muscle 2, and concerning bearing the pipe internal pressure, the supporting role of ring muscle to tube wall more can be brought into play reliably than being located near the position of inwall in the position that the ring muscle is located at close outer wall.
Embodiment 2 (referring to Fig. 2)
This example is pressed close to outer wall in tube wall position is provided with spirality hoop muscle 2, is provided with spirality hoop muscle 4 at the position of pressing close to inwall.This example also is provided with longitudinal rib 5 simultaneously, if longitudinal rib can reduce the longitudinal deformation of tubing, also can improve the mechanical strength of tubing axially loaded, needs bear the situation of larger axis to power in some use or course of working to adapt to, and further reach the purpose of saving material.
Embodiment 3 (referring to Fig. 3)
This example is pressed close to outer wall in tube wall position is provided with spirality hoop muscle 2, and the middle part also is provided with spirality hoop cavity 6 in the tube wall, and this hoop cavity can reduce cost satisfying the further materials that reduce under same diameter, moment of inertia, the mechanical property prerequisite.
This example adopts hot winding shaping process to make, and can form spirality hoop cavity in winding process.
