Problems solved by technology

However, the disadvantages of the ferrule connection are: the ferrule is a symmetrical half-piece type. When the ferrule is heavy and heavy, it needs to be aligned and lifted, and the connection is very difficult; the gasket is a non-standard seal, and the processing is complicated. Difficult to purchase, short useful life, high cost; difficult to install the gasket, easy to fall off when installing the ferrule; the barrel joint is also a non-standard part, the sealing surface is a non-standard design, difficult to process and purchase, and the cost is high

Abstract

The invention relates to a high-pressure quick-mount flange. The high-pressure quick-mount flange comprises two pairs of welding rings, a locating ring, a lens cushion, two half clamps, a locating bolt, a locating nut, a fastening bolt and a fastening nut, wherein the locating ring is mounted between the two pairs of welding rings; the lens cushion is mounted inside the locating ring; the two half clamps are mounted outside the two pairs of welding rings; one ends of the two half clamps are connected by the locating bolt and the locating nut; and the other ends of the two half clamps are connected in a fastening manner by the fastening bolt and the fastening nut. The high-pressure quick-mount flange provided by the invention has the advantages of easiness in mounting, low cost, simplicity and easiness in purchasing and processing, and easiness in standardizing popularization.

Description

technical field [0001] The invention relates to a detachable special device for pipeline connection, in particular to a high-pressure quick-install flange, whose maximum working pressure can reach 50MPa, and the maximum working temperature can reach 610°C, which can be applied to petroleum, chemical industry, metallurgy, electric power, Shipbuilding, nuclear industry, aerospace industry and other fields, the applicability is very wide. Background technique [0002] At present, the connection methods of industrial pipelines mainly include direct welding, threaded connection, flange connection and ferrule connection. Among them, the flange connection has the characteristics of detachability and high pressure resistance, and is the most widely used. The disadvantages of the blue plate connection type are: when the pipe diameter is large (greater than φ200mm), the pipe is heavy and difficult to install; the torque required by the bolt is large, and the installation is also very ...
