Abstract
A joint mechanism for thin-walled metal composite pipes, which comprises a pipe fitting, the heads of two pipelines, a sealing sleeve, a hold-down ring and a hold-down screw cap, wherein the two end surfaces of the pipe fitting are provided with a conical cavity bottom of which faces outwards; radial part of the sealing sleeve is also cone-shaped to match with the conical cavity of the pipe fitting; flanged lips are provided on the outside at the ends of the pipeline; ends of the pipeline are rested on the inner surface of the sealing sleeve; the hold-down ring is rested on the inner surface of the hold-down screw tap; the hold-down ring is arched at the cylinder part, crossing over the flanged lips on the outside of the pipeline and is contacted with the ends of the sealing sleeve. The utility model has the advantages of: excellent sealing property, no falling off even under huge pressure or external forces, excellent flexibility, and less requirements on the concentricity of pipelines.
Description
The utility model relates to a kind of pipe coupling mechanism, is particularly useful for the joint mechanism of anti-corrosion pipeline.
The anti-corrosion pipeline joint mechanism, strict especially to sealing requirements, in case poor sealing, corrosivity gas, liquid will be taken advantage of a weak point, the corrosion body.Anti-corrosion pipeline joint in the past, just the end face at joint adds a seal ring, is screwed into nut and compresses sealing, and its deficiency is poor sealing performance; The less reliable that connects comes off greatly or under the external force effect easily at pressure; Coaxality between pipeline and the pipeline requires high.
The purpose of this utility model is to overcome above-mentioned deficiency and thin-wall metal composite tube joint mechanism is provided, good seal performance, and good reliability of connection also is unlikely under the effect of or external force big at pressure and comes off; This joint connects flexible good, and is less demanding to the coaxality between pipeline and the pipeline.
Description of the present utility model is as follows: thin-wall metal composite tube joint mechanism is by the head of pipe fitting and two pipelines, and stuffing box gland, retainer ring, clamping nut are formed.There is outside thread at pipe fitting two, matches with the internal thread of clamping nut.The pipe fitting internal diameter is consistent with internal diameter of the pipeline, for anticorrosion, is added with the corrosion-resistant plastic lining layer at tube intracavity and inner cavity of pipe, and the plastic lining layer of pipe end also contains along the end of metallic conduit.The pipe fitting two ends have the chamber of the little taper in big the inside, outside, and stuffing box gland has taper too at radial component, matches with the conical cavity of pipe fitting.There is flange the end of pipeline at the external diameter position, and the end face of pipeline is against on the inner plane of stuffing box gland.Have retainer ring on the inner plane of clamping nut, retainer ring is arch at the cylinder position, and the end that strides across the flange of pipeline outer diameter part position and stuffing box gland is inconsistent.The precession clamping nut by retainer ring, makes stuffing box gland be close to the junction plane of pipe fitting and pipeline.
Description of drawings:
Figure is the sectional view of thin-wall metal composite tube joint of the present utility model mechanism.1-pipe fitting among the figure, 2-plastic lining layer, 3-stuffing box gland, 4-clamping nut, 5-retainer ring, 6-pipeline.
With connect internal diameter be the thin-wall metal composite tube joint mechanism of 40mm pipeline as embodiment of the present utility model, thin-wall metal composite tube joint mechanism is made up of the head of pipe fitting (1), two pipelines (6) and stuffing box gland (3), retainer ring (5), clamping nut (4).At pipe fitting (1) two outside thread is arranged, and the internal thread of clamping nut (4) matches.The internal diameter of pipe fitting (1) is consistent with the internal diameter of pipeline (6), φ 40mm.The long 100mm of pipe fitting (1).For anticorrosion, be added with corrosion-resistant plastic lining layer (2) at the inner chamber of pipe fitting (1) inner chamber and pipeline (6).The plastic lining layer (2) of pipeline (6) end also contains along the end of metallic conduit.The chamber that has the little taper in big the inside, outside at pipe fitting (1) two ends.Stuffing box gland (3) has taper too at radial component, matches with the conical cavity of pipe fitting (1).There is flange the end of pipeline (6) at the external diameter position, and flange exceeds body 1.5mm.The end face of pipeline (6) is against on the inner plane of stuffing box gland (3).Have retainer ring (5) on the inner plane of clamping nut (4), retainer ring (5) is arch at the cylinder position, strides across the flange at pipeline (6) external diameter position, and the end of stuffing box gland (3) contacts.Precession clamping nut (4) by retainer ring (5), makes stuffing box gland (3) be close to the junction plane of pipe fitting (1) and pipeline (6).For ease of screwing clamping nut, quadrangularly or Hexagon on the middle part external diameter of pipe fitting (1).
Advantage of the present utility model: good seal performance, the good reliability of connection, the work of or external force big at pressure Come off with lower also being unlikely; This joint connects flexible good, and the axiality between pipeline and the pipeline is required not High.
Claims (2)
1, thin-wall metal composite tube joint mechanism is made up of pipe fitting, the head of two pipelines, stuffing box gland, clamping nut, it is characterized in that there is flange the end of pipeline at the external diameter position, and the plastic lining layer of pipe end contains along the metallic conduit end.
2, thin-wall metal composite tube joint according to claim 1 mechanism is characterized in that retainer ring is arch at the cylinder position, and the end that strides across the flange of pipeline outer diameter part position and stuffing box gland is inconsistent.
