Abstract

The invention discloses a flange. The flange comprises a fixation flange and a connection flange. A fixation unit is arranged between the fixation flange and the connection flange, and a plurality of axial sliding grooves are formed in the fixation flange. The fixing unit comprises clamping claws arranged in the sliding grooves, and clamping portions for being fixedly connected with the connection flange are arranged on the clamping claws. A drive mechanism for driving the clamping claws to move axially is arranged on the fixation flange and comprises a drive rotation wheel rotating circumferentially, and guide rails wound spirally around the central axis are arranged on the drive rotation wheel. Guide grooves matched with the guide rails are formed in the clamping claws. The flange is convenient and quick to mount and dismount.

Description

technical field [0001] The present invention relates to a pipe connector, more specifically, it relates to a flange. Background technique [0002] Flanges are parts that are connected to each other between pipes, and are used for connection between pipe ends; there are bolt holes on the flange, and the bolts make the two flanges tightly connected. Flange connection is an important connection method in pipeline construction. Flange The connection is easy to use and can withstand high pressure. In industrial pipelines, flange connections are widely used. However, during the installation or removal of ordinary flanges, bolts need to be installed or removed one by one, which is time-consuming and laborious. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a flange that is easy to install and disassemble. [0004] In order to achieve the above object, the present invention provides the following...
