Problems solved by technology

[0002] At present, when fluid (such as compressed gas, water, oil) equipment is tested (pipeline cleaning, sealing), most of the two pipelines are connected by bolts evenly distributed on the end faces of the flanges. A single test requires repeated disassembly and assembly of several pipelines. Bolts not only take a lot of time, but also because the operator needs to use nuts to lock the bolts while moving the pipe flange, which greatly consumes the physical strength of the operator, and requires the cooperation of two or more operators.

Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] This embodiment provides a precise butt joint of pipelines and a fast locking joint, which includes a stepped flange 5, a sealing gasket 1 and two pull-type locking components.

[0024] Such as figure 1 As shown, two cylindrical pins protrude from the large-diameter end surface of the stepped flange 5, and the gasket 1 is set on the cylindrical pin, and is in contact with the large-diameter end surface of the stepped flange 5, and the small-diameter end of the stepped flange 5 is used for It is fixedly connected with the pipeline; two pull-type locking components are symmetrically fixed on the platform of the outer circumference of the large-diameter end of the stepped flange 5 along the axis of the pipeline.

[0025] Such as figure 1 , figure 2 As shown, the buckle locking assembly includes a base 11 , a pop-up stop pin 3 , a handle 4 , a buckl...

Abstract

The invention provides an accurate butting and rapid locking joint for pipelines. The accurate butting and rapid locking joint for the pipelines comprises a stepped flange, a sealing gasket and more than one buckle-type locking assembly, wherein a bulged cylindrical pin is arranged on the end surface of a large-diameter end of the stepped flange, the sealing gasket is installed on the cylindricalpin in a sleeved manner, and makes contact with the end surface of the large-diameter end of the stepped flange, and a small-diameter end of the stepped flange is used for being fixedly connected withone pipeline; and the more than one buckle-type locking assembly is uniformly fixed to a platform in the outer circumference of the large-diameter end of the stepped flange, the end surface of the large-diameter end of the stepped flange makes relative contact with the end surface of the outer side of the butted pipeline flange, the cylindrical pin forms clearance fit with an unthreaded hole of the butted pipeline flange to realize butting, and meanwhile, locking is realized through the matching of the buckle-type locking assembly and the end surface of the inner side of the butted pipeline flange. The accurate butting and rapid locking joint for the pipelines is capable of realizing accurate butting and rapid locking between pipelines, saving the labor, and increasing the efficiency.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a precise butt joint and fast locking joint of pipelines. Background technique [0002] At present, when fluid (such as compressed gas, water, oil) equipment is tested (pipeline cleaning, sealing), most of the two pipelines are connected by bolts evenly distributed on the end faces of the flanges. A single test requires repeated disassembly and assembly of several pipelines. Bolts not only take a lot of time, but also because the operator needs to use nuts to lock the bolts while moving the pipe flange, which greatly consumes the physical strength of the operator, and requires the cooperation of two or more operators. Finish. Therefore, in order to achieve the goal of "plug and play, convenient connection", it is urgent to design a joint that can realize quick docking and locking of pipelines. Contents of the invention [0003] In view of this, the present inventi...
