Abstract

The utility model discloses a telescopic flexible pipe piece. The telescopic flexible pipe piece comprises a body and an opening fastening bolt which is arranged at the external circle of an end socket of the body, wherein a connecting pipe which is communicated with the body is inserted into the body; a sealing ring is arranged at a joint of the body and the external circle of the connecting pipe; a fastening nut pushes a pressing ring, so the sealing ring is pressed against the inner parts of the connecting pipe and the end socket of the body; and an anti-pulling ring is arranged at the other end of the pressing ring and on the external circle surface of the connecting pipe inside the fastening nut. The telescopic flexible pipe piece has the advantages of sealing reliability, simple and reasonable structure, low cost, axial telescopic self-compensation, radial flexibility, high anti-pulling strength, high safety performance, long service life, convenience for parts replacement and the like.

Description

A kind of flexible bendable pipe fitting
Technical field
The utility model relates to a kind of pipe fitting, and it is reliable to be particularly related to a kind of sealing, and anti-pulling intensity is high and the flexible bendable pipe fitting of flexible self compensation function arranged.
Background technique
As everyone knows, in the pipeline construction of routine, pipe fitting is a requisite link in the pipe laying process; Be used for two pipelines are connected and sealed,, then can cause the leakage of fed sheet of a media in the pipeline if pipe fitting sealing is unreliable, anti-pulling not; Very easily cause security incident; Cause the economic loss that can't estimate, therefore high to the requirement of the sealing reliability between pipe fitting and the connecting tube, traditional connection pipe fitting ubiquity sealing effect is poor; The anti-pulling ability is low, complex structure, the shortcoming that construction is inconvenient, cost of material is high and construction cost is high.
The model utility content
The problem that the utility model will solve is the deficiency that overcomes in the background technique, and a kind of flexible bendable pipe fitting is provided, and this flexible bendable pipe fitting has sealing reliably, and is simple and reasonable, characteristics such as the high and flexible self compensation of anti-pulling intensity.
For addressing the above problem, the utility model is taked following technological scheme:
A kind of flexible bendable pipe fitting of the utility model; The opening clamping bolt that comprises body and body end bellmouth cylindrical place; Socket joint is equipped with the connecting tube that is connected with body in the body, and the connecting part of said body and connecting tube cylindrical is provided with seal ring, and said seal ring advances trim ring to be pressed within connecting tube and the body end bellmouth through tightening nut; The other end of said trim ring, and also be provided with the resistance to plucking circle at the inboard connecting tube periphery of tightening nut.
A corrective measure of the utility model is; The end bellmouth endoporus of said body is two ledge structures; Inboard one is connecting tube insertion limited step; One in the outside is an incline bench, and said seal ring places in the cavity of the incline bench in the body end bellmouth outside, trim ring and connecting tube formation.
The further corrective measure of the utility model is, the stereosphere of said resistance to plucking circle opening is arranged in the annular groove of connecting tube periphery.
Another corrective measure of the utility model is that said seal ring is an O type rubber seal.
The further corrective measure of another of the utility model is that said seal ring is the wedge-shaped rubber seal ring.
The beneficial effect of the utility model is: sealing is reliable, and simple and reasonable, cost is lower; But axial stretching self compensation and radially deflection, it is high to have anti-pulling intensity, and Safety performance is superior, and long service life is changed advantages such as component are easy.
Description of drawings
Fig. 1 is the structure cross-sectional schematic of the utility model.
Embodiment
As shown in Figure 1; A kind of flexible bendable pipe fitting of the utility model; The opening clamping bolt 2 that comprises body 1 and body end bellmouth cylindrical place; Socket joint is equipped with the connecting tube 7 that is connected with body 1 in the said body 1, and said body 1 is provided with seal ring 5 with the connecting part of connecting tube 7 cylindricals, and said seal ring 5 advances trim ring 4 to be pressed within connecting tube 7 and the body 1 end bellmouth through tightening nut 3; The other end of said trim ring 4, and also be provided with resistance to plucking circle 6 at inboard connecting tube 7 peripheries of tightening nut 3.
The end bellmouth endoporus of said body 1 is two ledge structures; Inboard one is that connecting tube 7 inserts limited step; One in the outside is an incline bench, and said seal ring 5 places in the cavity of the incline bench in the body bellmouth outside, 1 end, trim ring 4 and connecting tube 7 formation.
Said resistance to plucking circle 6 is the stereosphere of opening, is arranged in the annular groove of connecting tube 7 peripheries.
Said seal ring 5 is an O type rubber seal.
Said seal ring 5 is the wedge-shaped rubber seal ring.
After connecting tube 7 socket joints are fit in the end bellmouth of body 1; In the annular groove of promptly closely sheathed and connecting tube 7 outer round surface; When connecting tube 7 receive manage in pressure medium when drawing is moved outward with respect to tightening nut 3; The inclined-plane of tightening nut 3 endoporus tightly encircles and is pressed on the resistance to plucking circle 6, thereby produces the radial compaction active force, prevents that connecting tube 7 is drawn out in body 1 bellmouth to cause leakage.
