Abstract
The utility model discloses a kind of PE combustion gas pipe fitting, comprise body, inner body wall is axially equidistantly provided with some annular grooves, be provided with the bracing ring of hollow in annular groove, the outer half of bracing ring is divided and is positioned at annular groove, and inner halves is divided and is positioned at outside annular groove, the inner halves of adjacent supports circle is connected by some stiffening ribs between dividing, the inner halves that stiffening rib is distributed on bracing ring is divided circumferentially, and the inner and outer wall of stiffening rib is arc, and the outer wall of stiffening rib and inner body wall are fitted and arranged.PE combustion gas pipe fitting of the present utility model, structural strength is high, long service life.
Description
Technical field
The utility model relates to gas pipeline field, is specifically related to a kind of PE combustion gas pipe fitting.
Background technique
PE combustion gas pipe fitting is a kind of novel tube of conveying natural gas, artificial coal gas, liquefied petroleum gas (LPG), and it has feature that is corrosion-resistant, high tenacity, not easily leaks, but existing pipe fitting intensity is not high, the yielding cracking of Long-Time Service, user then wishes that compressive strength is the bigger the better, and is badly in need of improving.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of PE combustion gas pipe fitting, structural strength is high, long service life.
For achieving the above object, the technical solution of the utility model is: PE combustion gas pipe fitting, comprise body, described inner body wall is axially equidistantly provided with some annular grooves, the bracing ring of hollow is provided with in described annular groove, the outer half of described bracing ring is divided and is positioned at annular groove, inner halves is divided and is positioned at outside annular groove, the inner halves of adjacent supports circle is connected by some stiffening ribs between dividing, the inner halves that described stiffening rib is distributed on bracing ring is divided circumferentially, the inner and outer wall of stiffening rib is arc, and the outer wall of stiffening rib and inner body wall are fitted and arranged.
The beneficial effects of the utility model: " skeleton " that together constituted its inside by bracing ring in inner body wall and stiffening rib, overall construction intensity improves greatly, and Long-Time Service is strain cracking not easily, long service life.
Accompanying drawing explanation
Fig. 1 is partial structurtes schematic diagram of the present utility model;
Fig. 2 be in Fig. 1 A-A to sectional view.
In figure: body 1, annular groove 11, bracing ring 2, stiffening rib 3.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, PE combustion gas pipe fitting, comprise body 1, described body 1 inwall is axially equidistantly provided with some annular grooves 11, the bracing ring 2 of hollow is provided with in described annular groove 11, bracing ring 2 adopts metal material, the outer half of described bracing ring 2 is divided and is positioned at annular groove 11, inner halves is divided and is positioned at outside annular groove 11, the inner halves of adjacent supports circle 2 is connected by some stiffening ribs 3 between dividing, stiffening rib 3 adopts metal material, the inner halves that described stiffening rib 3 is distributed on bracing ring 2 is divided circumferentially, the inner and outer wall of stiffening rib 3 is arc, the outer wall of stiffening rib 3 and body 1 inwall are fitted and are arranged, add the area of contact of stiffening rib 3 and body 1 inwall, bracing ring 2 and stiffening rib 3 together constitute " skeleton " of body 1 inside, this PE combustion gas pipe fitting overall construction intensity is improved greatly, Long-Time Service is strain cracking not easily, long service life.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
