Pipeline rapid connecting flange and pipeline rapid connecting method

Abstract

The invention discloses a pipeline rapid connecting flange and a pipeline rapid connecting method. The pipeline rapid connecting flange comprises a first flange and a second flange, and the first flange is detachably and fixedly mounted on the second flange. A left inserted connection groove is formed between a first left barrel and a second left barrel, and a right inserting connection groove with the right end being opened is arranged in a right barrel. A gear ring is arranged on the side wall of an inner hole of the second flange, and a transmission barrel is arranged in the gear ring. A right cone is arranged at the right end of the transmission barrel, and the left end of the transmission barrel is in threaded connection with a left cone. A left locating rod and a left spring are arranged on the first left barrel, and a right locating rod and a right spring are arranged on the right barrel. A left connecting pipe is arranged in the left inserted connection groove, a left locatinghole is arranged on the left connecting pipe, a right connecting pipe is arranged in the right inserted connection groove, and a right locating hole is arranged on the right connecting pipe. A power assembly is arranged in the second flange. The pipeline rapid connecting flange is simple in structure and reliable in connection.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection devices, in particular to a pipeline quick connection flange and a pipeline quick connection method. Background technique [0002] Flanges are also called flanges or flanges, parts that connect pipes to pipes. There are holes on the flange, and bolts can be worn. It usually refers to opening several holes for fixing on the periphery of a disc-like metal body for connecting other things. The existing flange connection is to fix two pipelines, pipe fittings or equipment respectively on a flange plate first, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Flange connection is an important connection method in pipeline construction. Flange connection is easy to use and can withstand high pressure. In industrial pipelines, flange connection is widely used. Generally, flanges and pipes need to be connected together by welding, ...

AI Technical Summary

Problems solved by technology

Generally, flanges and pipes need to be connected together by welding, which has a long construction period and large investment, which brings great losses to production and the environment, so further improvement and improvement are extremely needed.
