Description

Socket connecting structure of high-modulus FRPP radial double-flat-wall reinforced pipe

Technical Field

The utility model belongs to the technical field of plastic pipes, and relates to a socket connecting structure of a high-modulus FRPP radial double-flat-wall reinforced pipe.

Background

The high-modulus FRPP radial double-flat-wall reinforced pipe is an A-shaped pipe with an inner pipe wall and an outer pipe wall both being smooth planes, and is widely applied to various projects such as water supply and drainage. Wherein the sealing washer need with the bellmouth joint inner wall and pipeline socket end outer wall support tightly in order to guarantee sealed effect, but two pipeline butt joint installation in-process simultaneously, pipeline radial pressure-bearing, the axis between spigot end and the bellmouth probably has the deviation, does not realize coaxial, and the radial pressure-bearing of the spigot end of pipeline is inhomogeneous can take place deformation, and the reliability worsens, to this, can improve the anti deformability of the spigot end of pipeline and spigot end through increasing the thickness of spigot end and spigot end.

The socket of current pipeline mainly has two kinds of preparation methods, firstly with pipeline integrated into one piece, secondly with pipeline and socket pipe fitting respectively the shaping back, be connected to the pipeline with the bell and spigot pipe fitting through later stage processing on, but above-mentioned method all has inadequately, integrated into one piece's pipeline makes pipeline bell and spigot position thickness can not be done thickly, bell and spigot thickness thicknessly can influence whole production efficiency, the mode of later stage processing though can improve the thickness of bell and spigot pipe fitting, but increases manufacturing procedure and troublesome poeration.

Disclosure of Invention

The utility model aims to solve the problems in the prior art, and provides a bellmouth connecting structure of a high-modulus FRPP radial double-flat-wall reinforced pipe, which aims to solve the technical problems that: how to improve the reliability of the pipe socket connection.

The purpose of the utility model can be realized by the following technical scheme: the utility model provides a bellmouth connection structure of radial two flat walls of high modulus FRPP reinforcing tubular product, includes two pipelines and has the bellmouth joint of two bellmouth ends, its characterized in that, every pipeline includes the pipe base layer and wraps up the outer cladding of the pipe base layer outward, be provided with the fibre belting layer between pipe base layer and the outer cladding, two pipelines insert respectively and establish the bellmouth end at the bellmouth joint, and are provided with the sealing washer between the outer cladding of every pipeline and the inner wall of bellmouth joint.

The radial load that the fibre belting can transmit the pipeline each other between outer coating and pipe layer and receive, the radial bearing capacity of pipeline can be strengthened in the fibre belting, improve the structural strength and the bending resistance ability of pipeline, improve through the inner structure to the pipeline, make the radial bearing capacity of every department on the pipeline all can strengthen, thereby the pipeline is when the socket end that inserts the bellmouth joint, the pipeline has better ability of resisting self deformation, improve the reliability that the bellmouth is connected, manage simultaneously and can not do thickly to the tip thickness that inserts the bellmouth joint, the pipeline can adopt integrated into one piece's mode, guarantee whole production efficiency.

In the bellmouth connection structure of the high-modulus FRPP radial double-flat-wall reinforced pipe, the middle part of the bellmouth joint is inwards recessed to form a supporting part, the inner wall of the supporting part is arc-shaped, and the end parts of the two pipelines are respectively supported against the two sides of the supporting part. The tip of pipeline is the plane, and it is circular-arc to design the portion of supporting into, makes to support for line contact between portion and the pipeline for area of contact between circular-arc portion of supporting and the pipeline tip is less than in the massive area of contact between portion of supporting and the pipeline tip, reduces the machining precision requirement of supporting inner wall and pipeline terminal surface, thereby makes to support between portion of supporting and the pipeline tip and support inseparabler, guarantees the stability of connecting.

In the bell mouth connecting structure of the high-modulus FRPP radial double-flat-wall reinforced pipe, the outer walls of the outer cladding layers of all the pipelines are flat. Therefore, the forming speed of each position of the pipeline is kept consistent, and the production efficiency of the pipeline is ensured.

In the bell mouth connecting structure of the high-modulus FRPP radial double-flat-wall reinforced pipe, the inner wall of the bell mouth joint is provided with a limiting groove which is recessed inwards, and the sealing ring is positioned in the limiting groove. Because the outer wall of pipeline is the plane, when the installation, the pipeline outer wall is unanimous with the frictional force between the sealing washer everywhere, if insert the pipeline bellmouth joint inner stroke too much, can cause the sealing washer upset, through add the spacing groove on the inner wall that the bellmouth connects, the sealing washer is located the spacing inslot, avoids the sealing washer upset to appear, guarantees to assemble stably between pipeline and the bellmouth joint.

In the bell mouth connecting structure of the high-modulus FRPP radial double-flat-wall reinforced pipe, the outer side wall of the pipe blank layer is provided with a plurality of protruding annular reinforcing ribs which are arranged at equal intervals along the axial direction of the pipe blank layer. The radial bearing capacity of the pipeline is enhanced through the reinforcing rib structure additionally arranged on the pipe blank layer, the reinforcing ribs arranged at equal intervals ensure that the pipeline has better structural strength everywhere, and therefore the two ends of the pipeline are ensured to keep better anti-deformation effect after being inserted into the socket joint.

Compared with the prior art, the bell mouth connecting structure of the high-modulus FRPP radial double-flat-wall reinforced pipe has the following advantages: the pipeline structure formed by the pipe blank layer, the fiber belt layer and the outer coating layer has higher strength, and can maintain the shape of the pipeline structure when the pipe blank layer, the fiber belt layer and the outer coating layer are inserted into the socket joint, so that stable connection is realized; meanwhile, the structure of the pipeline is reinforced, the outer wall of the outer coating layer of the pipeline can be set to be a plane, the whole pipeline can be integrally formed, and the whole production efficiency is guaranteed.
