Abstract
The utility model discloses a pipeline rapid butt joint device, which is an annular assembly structure formed by encircling two semi-annular sub-assemblies, wherein a positioning ring groove with a trapezoidal section is processed on an inner ring of the annular assembly, and bolt connecting holes which correspond to each other are processed at the butt joint ends of the two semi-annular sub-assemblies; the outer edge of the mouth part of the butt joint end of each pipeline to be butted is provided with a positioning ring for butting, and the rear end surface of the positioning ring is processed into a conical surface corresponding to the side taper of the positioning ring groove of the annular assembly; two semi-annular divide the piece to embrace to cup joint two holding rings departments of treating the butt joint pipeline, two semi-annular divide the butt joint end of piece to pass through bolt and nut to fix and form the ring and close the piece, screw up the in-process at the bolt, the ring closes the piece and treats two butt joint pipeline axial fastening through the conical surface of holding ring groove both sides. The quick pipeline butt joint device can be used for quickly and reliably butt joint pipelines.
Description
Technical Field
The utility model relates to a quick pipeline butt joint device, and belongs to the technical field of fluid conveying.
Background
When fluid is conveyed, because the destination position is uncertain, pipeline butt joint is often adopted for conveying, most of the existing common pipelines are hard pipes, and the existing pipeline butt joint relates to pipeline butt joint, generally adopts flange connection, welding, threaded connection, groove type connection and the like, and has the disadvantages of complex operation, poor sealing performance and high working strength.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems of complex operation, poor sealing performance, high working strength and the like of a pipeline butt joint method, and provides a pipeline quick butt joint device.
The purpose of the utility model is realized by the following technical scheme:
the utility model relates to a quick butt joint device for pipelines, which is an annular assembly structure formed by encircling two semi-annular sub-assemblies, wherein a positioning ring groove with a trapezoidal section is processed on an inner ring of the annular assembly, and bolt connecting holes which are mutually corresponding are processed at the butt joint ends of the two semi-annular sub-assemblies;
the outer edge of the mouth part of the butt joint end of each pipeline to be butted is provided with a positioning ring for butting, the rear end surface of the positioning ring is processed into a conical surface corresponding to the side taper of the positioning ring groove of the annular assembly, and the axial length of the rear end surface of the positioning ring is greater than that of the side surface of the positioning ring groove of the annular assembly; the sum of the axial lengths of the outer rings of the positioning rings of the two pipelines to be butted is matched with the width of the bottom of the positioning ring groove of the annular assembly;
two semi-annular divide the piece to embrace to cup joint two holding rings departments of treating the butt joint pipeline, two semi-annular divide the butt joint end of piece to pass through bolt and nut to fix and form the ring and close the piece, screw up the in-process at the bolt, the ring closes the piece and treats two butt joint pipeline axial fastening through the conical surface of holding ring groove both sides.
Advantageous effects
The pipeline quick butt joint device has the advantages of simple structure, convenience in operation, capability of quickly and reliably butting pipelines, effective solving of the problems of positioning and leakage in pipeline butt joint, low centering requirement in installation and good sealing performance.
