Abstract

The utility model discloses a pipeline connecting structure with flanges, and the pipeline connecting structure includes two fixing flanges connected through bolts, pipelines fixedly connected with corresponding flanges respectively, as well as a sealing gasket arranged between the two fixing flanges, wherein one end surface at one end of the sealing gasket is a spherical surface. The pipeline connecting structure with the flanges disclosed by the utility model is contacted with the corresponding flanges or mouths of corresponding pipelines to seal through the spherical surface arranged on the sealing gasket; when the pipeline connecting structure is used, the general structures of the pipelines can remain unchanged, and the adjustability of the butt jointed pipelines can be realized at the same time through utilizing the property of the spherical surface, so that the error between the pipelines can be eliminated, at the same time, the angle arrangement of straight pipes can be realized, the convenience of pipeline arrangement is greatly improved, and the pipeline connecting structure with the flanges has high universality.

Description

A kind of flanged (FLGD) pipe connecting structure
Technical field
The utility model relates to a kind of flanged (FLGD) pipe connecting structure.
Background technique
During connecting, use in existing pipeline flange that the 2-section pipe road is connected usually.Conventional flange mainly contains face-flange, male and female flange, ring joint face flange etc.; But at present; Adopt the linkage structure of these flanges to be merely able to the 2-section pipe road is rigidly connected, and can't the positional error between the pipeline be adjusted, be difficult to satisfy the assembled in situ requirement.
The model utility content
The purpose of the utility model is: a kind of flanged (FLGD) pipe connecting structure simple in structure, easy to use is provided, the requirement that can adjust the pipeline error when satisfying on-the-spot the installation.
The technological scheme of the utility model is: a kind of flanged (FLGD) pipe connecting structure; Comprise with bolted two fastening flanges, the pipeline that is fixedly connected with companion flange respectively and be provided with the sealing gasket between two fastening flanges that one end end face of described sealing gasket is a sphere.
The mouth of pipe of a said pipeline wherein stretches between the opposing side of two flanges, and is provided with the conical enlarging with the sphere corresponding matching of said sealing gasket at this mouth of pipe.
The other end end face of described sealing gasket is provided with the insertion section of inserting the companion flange endoporus.
Flanged (FLGD) pipe connecting structure of the utility model contacts with the mouth of pipe of companion flange or pipeline through the sphere that is provided with on the sealing gasket and realizes sealing; During use; Can when keeping the pipeline general structure constant, utilize the achieve a butt joint direction of pipeline of global characteristics adjustable, thereby eliminate the positional error of pipeline enclosure, can also realize that straight tube band angle arranges simultaneously; Convenience to line arrangement improves a lot, and has high generality.
Description of drawings
Fig. 1 is the structural representation of the flanged (FLGD) pipe connecting structure specific embodiment of the utility model.
Embodiment
Flanged (FLGD) pipe connecting structure of the utility model mainly is made up of two fastening flanges that are oppositely arranged, the pipeline that connects with corresponding fastening flange respectively and the sealing gasket of being located at two fastening flange supports.Its specific embodiment is as shown in Figure 1, and one of them fastening flange adopts butt welding hubbed flange 1, and another fastening flange adopts flat flange 2, two flanges 1, is fixedly connected through bolt 7 between 2.Be connected with pipeline 4 on the butt welding hubbed flange 1; Be fixedly connected with pipeline 3 on the flat flange 2; Be contained in two flanges 1, be provided with sealing gasket 5 between 2, sealing pad 5 is a sphere towards an end end face of flat flange 2, is to guarantee reliable sealing between flat flange 2 and corresponding pipeline 3 that connects and the sealing pad 5; The endoporus that the mouth of pipe of this pipeline 3 passes flat flange 2 extend between the opposing side of two flanges 1,2; And being provided with conical enlarging 6 at the mouth of pipe of this pipeline 3, the sphere of sealing gasket 5 and this taper shape enlarging 6 corresponding matching make when assembling pipeline 3 can depart from the center line of pipeline 4; In certain angle, adjust, thereby eliminate the positional error that exists between two pipelines.Convenience when installing for improving sealing pad 5, it is provided with the insertion section 50 of inserting this flange endoporus at sealing gasket 5 on the end face of weldering hubbed flange 1.
