Problems solved by technology

In some larger flanges, the demand for bolts also increases, which not only causes a burden on the cost, but also is not conducive to the lightweight of the equipment
At present, the symmetrical installation of flanges used in domestic production will have errors or misalignment, resulting in poor sealing effect and often causing materials to overflow from the connection, especially for pipelines that have large vibrations or transport large impact fluids , Leakage at the flange sealing surface occurs from time to time

Embodiment Construction

[0018] The present invention will be further described below with reference to the accompanying drawings. As shown in the accompanying drawings, the present invention provides an easy-to-center pressure-resistant flange. The large end of the conical shell 5 is welded to the flange, and the small end is a straight edge section and the connected pipeline adopts a butt welding connection type; the flange is welded. 2. The oval bosses 1 are evenly distributed at the ends, and the ends of the flanges that appear in pairs are open with oval grooves; the ends of the flange 2 are evenly distributed with bolt holes 4, and the bolt holes 4 are connected to the oval boss (groove) 1. The spaced arrangement and the number of arrangements can be determined according to the pipeline pressure; the reinforcing rib 3 is welded and connected between the conical shell 5 and the flange plate 2, which effectively improves the rigidity of the flange plate. When the flanges act in pairs, an annular g...

Abstract

The invention relates to a compression-resisting flange easily achieving alignment. The compression-resisting flange is composed of oval bosses, a flange plate, reinforcing ribs, bolt holes and a coneshell, wherein the oval bosses (grooves) are evenly distributed on the surface of the flange plate; the bolt holes are evenly distributed in the flange plate, and the bolt holes and the oval bosses (grooves) are distributed alternatively, the usage quantity of bolts is reduced, and the purpose of lightweight is achieved on the premise of not affecting the compression resistance of the flange; thereinforcing ribs are welded between the cone shell and the flange plate and used for improving the stiffness of the flange, and the situation that excessive buckling deformation occurs to the flangedue to stiffness insufficiency is avoided; and the connection section of the cone shell has a certain buffer effect for high-impact fluid, and thus the compression resistance of the flange is furtherimproved.

Description

technical field [0001] The invention relates to a flange structure, in particular to an easy-centering and pressure-resistant butt-welding flange, which belongs to the field of pressure pipeline connection design. Background technique [0002] In the field of machinery, the flange is a widely used connection device, and plays a vital role in the field of pipelines and pressure vessels; once the flange is damaged, it will affect the entire system, and even cause great personal casualties. ; The pressure resistance of the flange is an important indicator to measure the quality of the flange, and it is also a condition to ensure the normal operation of the pipeline. Especially in the connection between the pressure vessel and the pipeline and the connection between the pressure pipeline, the requirements for the flange are higher, which not only increases the requirements on the material and preparation process, but also increases the requirements on the structural design. Fla...
