A kind of pipeline quick connection flange and pipeline quick connection method

Abstract

The invention discloses a pipeline quick connection flange and a pipeline quick connection method. The pipeline quick connection flange includes a first flange and a second flange, and the first flange is detachably fixed on the second flange. On the flange; a left insertion slot is formed between the first left cylinder and the second left cylinder, and a right insertion slot with an open right end is arranged in the right cylinder; the inner hole side wall of the second flange is provided with a gear ring, The gear ring is provided with a transmission cylinder; the right end of the transmission cylinder is provided with a right cone, and the left end of the transmission cylinder is threadedly connected with a left cone; the left cylinder is provided with a left positioning rod and a left spring, The right cylinder body is provided with a right positioning rod and a right spring; a left connecting tube is arranged in the left insertion slot, a left positioning hole is arranged on the left connecting tube, and a right connection is arranged in the right insertion slot The right connecting pipe is provided with a right positioning hole; the second flange is provided with a power component; the pipeline quick connection flange is not only simple in structure, but also 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] Flange, also known as flange or flange, is a part that connects pipes to pipes. There are holes on the flange, which can be used for bolts, which usually means that several fixed holes are opened around the periphery of a disk-like metal body for connecting other things. The existing flange connection is to fix two pipes, pipe fittings or equipment 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, the flange and the pipeline need to be connected by welding, the...

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.
