The utility model CN201377653Y previously filed by the applicant discloses a non-reducing plastic gap bridge elbow piece, which is composed of a gap bridge elbow and two elbows connected to the two ends of the gap bridge elbow respectively, wherein the gap bridge elbow is in a smooth arc shape, the end opening of the elbow is a straight pipe interface, and the inner diameter of each cross section of the gap bridge elbow is the same. The bent pipe and the elbow are formed by one-time injection molding. The elbows at the two ends of the bent pipe fitting of the gap bridge are connected with the pipe, and the inner diameter of the bent pipe fitting of the gap bridge is the same as the inner diameter of the pipe. The bridging elbow part of the non-reducing plastic bridging elbow part is in a smooth arc shape, the inner diameter of each cross section of the bridging elbow is the same, and the inner diameter of the bridging elbow is the same as that of the connected pipe, so that the increase of fluid resistance caused by the reduction of the inner diameter is avoided, the structure is compact, the installation is convenient, and the following defects are found in the specific practice process: when the bridge elbow assembly is plugged with another elbow, the problem that the pipeline is easy to leak due to the fact that the plug cannot be plugged in place exists, or the plug is excessively plugged, so that the socket is deformed or even damaged inside, and the inner diameter is reduced; and excessive grafting can cause the socket of the bent assembly of the bridge to enter the straight-line section of the socket of another elbow, so that the inner diameter is further reduced, and even serious people cause the elbow to be easily damaged and leaked.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a curved subassembly of gap bridge that is favorable to the pipeline erection construction is provided to solve the defect that exists among the prior art.

The utility model provides an above-mentioned technical problem's technical scheme as follows:

a gap bridge bent component beneficial to pipeline installation and construction comprises a gap bridge bent pipe in the middle and elbows connected with two ends of the gap bridge bent pipe, wherein the elbow at one end and the gap bridge bent pipe are integrally formed in an injection molding mode, the elbow at the other end is a split type elbow and is connected with the gap bridge bent pipe in a plugging mode, the split type elbow is provided with a socket, and the gap bridge bent pipe is provided with a socket; or the split elbow is provided with a socket, and the bridge elbow is provided with a socket; the outer surface of the socket is provided with a step, the inner surface of the port of the socket is provided with an annular concave surface with the same length as the step, and the step is matched with the annular concave surface to realize insertion and fixation; the height of the annular concave surface is equal to the thickness of the socket pipe at the step;

furthermore, the bridge elbow is in a smooth arc-shaped tube shape, and the inner diameters of the cross sections of the bridge elbow are the same;

furthermore, two ports of the split elbow are both a socket or a spigot or one port is a socket and the other port is a spigot; various pipes can be conveniently connected;

furthermore, the material of the bent pipe and the elbow of the gap bridge is thermoplastic plastics;

the utility model has the advantages that:

1. because the step and the annular concave surface are matched, inserted and fixed, the bent bridge passing pipe cannot be inserted or excessively inserted, so that the bent bridge passing assembly is ensured to be inserted well, and the inside of the bent bridge passing pipe is not reduced.

2. Because the bridge bend assembly and the elbow are not reduced in diameter, the fluid resistance cannot be increased, and therefore the medium conveying with large flow and low local head loss can be realized.

Drawings

FIG. 1 is a schematic sectional view of the present invention;

FIG. 2 is a schematic view of the split cross-section structure of the present invention;

the reference numerals are explained below:

1. the bridge-crossing elbow comprises a bridge-crossing elbow 2, an elbow 3, a split elbow 4, a socket 5, a socket 6, a step 7 and an annular concave surface;

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

A bent assembly of a gap bridge beneficial to pipeline installation and construction comprises a bent tube 1 of the gap bridge in the middle and elbows connected with two ends of the bent tube 1 of the gap bridge, wherein an elbow 2 at one end and the bent tube of the gap bridge are integrally formed by injection molding, an elbow at the other end is a split-type elbow 3 which is connected with the bent tube of the gap bridge in a plugging mode, the split-type elbow is provided with a socket 5, and the bent tube of the gap bridge is provided with a socket 4; or the split elbow is provided with a socket 4, and the bridge elbow is provided with a socket 5; the outer surface of the socket is provided with a step 6, the inner surface of the port of the socket 5 is provided with an annular concave surface 7 with the same length as the step, and the step and the annular concave surface are matched to realize insertion and fixation; the height of the annular concave surface 7 is equal to the thickness of the socket pipe at the step 6;

in a specific embodiment, the bent bridge-crossing component has a certain span height H1, and when the pipelines need to be arranged in a cross manner, the bent bridge-crossing component has a certain span H2, as shown in fig. 1-2, the bent bridge-crossing component can completely cross over the pipes with specific outer diameters, and the crossed pipes cannot be extruded, so that each pipe can be tightly attached to the bottom of the pipeline installation groove, and the phenomena of infirmity backfill and hollowing which may occur when the building material is backfilled into the installation groove are avoided; the step and the annular concave surface are matched to effectively realize splicing and fixing, so that incomplete splicing or excessive splicing can be avoided; meanwhile, the height of the annular concave surface is equal to the thickness of the socket pipe at the step, so that the inner diameters of the bridge elbow and the elbow are the same, and the resistance increase phenomenon caused by the reduction of the inner diameter is further reduced;

more specifically, the bridge elbow is in a smooth arc-shaped tube shape, and the inner diameters of the cross sections of the bridge elbow are the same;

therefore, when fluid flows through the bridge elbow, the fluid resistance cannot be increased due to the reduction of the inner diameter, and the medium conveying with large flow and low local head loss can be realized;

more specifically, two ports of the split elbow are both a socket or a spigot or one port is a socket and the other port is a spigot; various pipes can be conveniently connected;

when in manufacturing, the material of the bent pipe and the elbow of the gap bridge is thermoplastic plastics;
