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 a pipe precise butt joint and fast locking joint, which includes a stepped flange, a sealing gasket and more than one snap-type locking component; a protruding cylindrical pin is provided on the large diameter end of the stepped flange, The gasket is set on the cylindrical pin and is in contact with the large-diameter end of the stepped flange, which is used for solid connection with the pipe; more than one pull-type locking component is evenly fixed outside the large-diameter end of the stepped flange On the circumferential platform, the large-diameter end face of the stepped flange is in relative contact with the outer end face of the butt pipe flange, and the cylindrical pin is matched with the light hole of the butt pipe flange to realize the butt joint. The fit of the inner end face of the flange realizes locking. The invention can realize precise docking and fast locking between pipelines, save manpower and improve 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...
