Abstract

The invention belongs to the technical field of flanges, in particular to a pressure vessel flange and a processing method thereof, comprising a flange plate with several center-symmetrically distributed screw holes, and the middle position of the top end of the flange plate There are symmetrically distributed connecting shaft columns fixed at the middle of the center and the bottom end, and the outer wall of the connecting shaft column is fixed with threaded protrusions distributed in a spiral shape; the top and bottom ends of the flange are integrated by using the threaded protrusions The limit groove of the formed connection can snap the side of the gasket in contact with the flange into the limit groove when installing the gasket, and the inner wall of the gasket is provided with a thread groove that matches the thread protrusion , enhance the connection stability between the gasket and the connecting shaft column, and make the contact between the gasket and the flange closer, not easy to loose and slip, so that there is an appropriate pre-tightening force between the flange and the gasket, It can ensure that the gasket can retain a certain sealing specific pressure when it is working, and enhance the stability of the gasket.

Description

Technical field [0001] The present invention belongs to the field of flanges, and specific relates to pressure vessel flanges and their processing methods. Background technique [0002] The pressure vessel is the most widely used equipment in the petrochemical industry, one of the main production tools of the petrochemical industry. Due to process requirements and equipment internal parts installation, maintenance needs, pressure vessels often need to set the container flange, and the pressure vessel flange is divided into: overall flanges, logs flanges and arbitrary flanges. Standard pressure vessel flanges have three types: 甲 平 法 法,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Flanges and their gaskets, the fasteners are collectively referred to as the flange joint, the flange joint is extremely common in engineering design, involving a very wide range of components, is also a key part of the engineering design and us...
