Abstract
A clamp type straight pipe connecting piece is a circular pipe fitting formed by two semicircular pipes (1) in a butt joint mode, one sides of the two semicircular pipes are connected through a hinge (4), a fixing lug plate (3) with a mounting hole is welded on the other side of the two semicircular pipes, and after the two semicircular pipes are in butt joint, the two semicircular pipes are connected and fastened through a group of connecting bolts (5) penetrating through the mounting holes of the fixing lug plate; the inner walls of the two semicircular tubes are coated with a flexible coating (2). The utility model discloses simple structure, the maintenance pipeline is swift convenient.
Description
Technical Field
The utility model relates to a worker civil engineering field pipe erection connects technical field, specifically is a embrace formula of clamp straight tube connecting piece that is used for non-pressure or low pressure pipeline maintenance.
Background
Various non-pressure or low-pressure liquid pipelines in industrial and civil buildings are damaged by breakage, breakage and the like caused by various reasons in the installation and use processes. Damage to installed pipes, particularly large diameter pipes, is difficult to remove and repair because the pipes are difficult to remove and move.
Disclosure of Invention
The utility model aims at solving the difficult problem in the actual construction, provide one kind and can simply and conveniently maintain the clamp formula straight tube connecting piece that embraces that damages the pipeline swiftly.
The utility model adopts the technical scheme as follows:
a clamp type straight pipe connecting piece is a circular pipe fitting formed by two semicircular pipes in a butt joint mode, one sides of the two semicircular pipes are connected through a hinge, a fixing lug plate with a mounting hole is welded on the other side of the two semicircular pipes, and after the two semicircular pipes are in butt joint, the two semicircular pipes are connected and fastened through a group of connecting bolts penetrating through the mounting holes of the fixing lug plate; the inner walls of the two semicircular tubes are coated with flexible coatings.
The length of the semicircular pipe is not less than 1.2 times of the diameter of the clamped straight pipe. The hinge connecting ends of the two semicircular tubes are connected by a tongue-and-groove, and the overlapping sections of the semicircular tubes for fixing the ear plate connecting ends are also connected by the tongue-and-groove. The tongue and groove at the tongue and groove joint is also coated with a flexible coating. The flexible coating is made of polyurethane or acrylate, and the thickness of the flexible coating is not less than 1.5 mm.
Adopt the utility model discloses during the maintenance fracture, damaged pipeline especially are difficult to dismantle, the major diameter pipeline of removal, only need with the utility model discloses a two semi-circular pipes are opened along the hinge, then press from both sides and embrace at the fracture or the damaged position of pipeline, then fold two semi-circular pipes, pass the mounting hole of fixed otic placode with a set of connecting bolt, with two semi-circular pipe connection fastens can. The inner walls of the two semicircular tubes are coated with flexible coatings, so that the two semicircular tubes can be tightly attached to a maintained pipeline, and the pipeline after maintenance is prevented from leaking. The utility model discloses simple structure, the maintenance pipeline is swift convenient.

FIGS. 1-1 and 1-2 are schematic views of the present invention when opened and closed, respectively;
FIG. 2 is a schematic view of the present invention installed in a damaged area of a pipeline;
fig. 3-1 and 3-2 are schematic diagrams of the tongue-and-groove connection of the hinge connection end and the fixed ear plate connection end, respectively, after installation of the present invention.
Detailed Description
As shown in fig. 1-1 and 1-2, a clamp type straight pipe connecting piece is a circular pipe fitting formed by two semicircular pipes 1 in a butt joint mode, one sides of the two semicircular pipes are connected through a hinge 4, a fixing lug plate 3 is welded to the other side of the two semicircular pipes, a row of mounting holes are machined in the fixing lug plate, and after the two semicircular pipes are in butt joint, the two semicircular pipes are connected and fastened through a group of connecting bolts 5 penetrating through the mounting holes of the fixing lug plate; the inner walls of the two semi-circular tubes are coated with a flexible coating 2. Adopt the utility model discloses during maintenance fracture, damaged pipeline, only need will the utility model discloses a two semi-circular pipes are opened along the hinge, then press from both sides and embrace at the fracture or the damaged position of pipeline, then fold two semi-circular pipes, pass the mounting hole of fixed otic placode with a set of connecting bolt, with two semi-circular pipe connection fastening can, as shown in fig. 2. The flexible coatings coated on the inner walls of the two semicircular tubes can be tightly attached to the maintained pipeline, so that the maintained pipeline is prevented from leaking. The hinge connecting ends of the two semicircular tubes are connected by the grooves and the tongues, the overlapping sections of the semicircular tubes for fixing the ear plate connecting ends are also connected by the grooves and the tongues, as shown in figures 3-1 and 3-2, the groove and the tongues are just tightly squeezed after clamping by the meshing length of the grooves and the tongues, the grooves and the tongues at the groove and tongue connecting positions are coated with the flexible coating 2, the groove and tongue connecting structures and the coated flexible coating can enable the connecting positions to be tightly attached, good sealing is formed, and leakage after pipeline maintenance is avoided. The flexible coating 2 is made of polyurethane or acrylate, and the thickness of the flexible coating is not less than 1.5 mm. The length of the semicircular pipe is generally not less than 1.2 times of the pipe diameter of the clamped straight pipe 6. The semicircular pipe of the utility model can be made of stainless steel, aluminum alloy, cast iron and other pipe fittings.
