Description

Leakage-resistant composite plastic pipe fitting

Technical Field

The utility model relates to the technical field of plastic pipe fittings, in particular to a leakage-resistant composite plastic pipe fitting.

Background

Plastic pipes are generally manufactured by extrusion processing of synthetic resins, i.e. polyesters, as raw materials, with the addition of stabilizers, lubricants, plasticizers, etc. in a "plastic" manner in a pipe making machine. The pipe is mainly used as a pipeline for a tap water supply system of a house building, a sanitary pipe for drainage, exhaust and pollution discharge, an underground drainage pipe system, a rainwater pipe, a threading pipe for wire installation and assembly, and the like.

The composite plastic pipe fitting is widely applied due to the stable chemical structure, light weight and small angle bending, but the water seepage problem after bending is serious, and in order to improve the anti-seepage capability of the pipe fitting, hot melt adhesive is often used for connection and fixation, so that the anti-seepage composite plastic pipe fitting is provided.

Disclosure of Invention

The utility model aims to overcome the existing defects, and provides the leakage-resistant composite plastic pipe fitting which utilizes the ductility of a hot melt adhesive film and the expansibility of the hot melt adhesive film to ensure that the pipeline cannot generate larger internal structural deformation when being bent, thereby improving the leakage-resistant capability of the pipeline and effectively solving the problems in the background technology.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an impervious composite plastic pipe fitting, includes the connecting pipe main part, the connecting pipe main part passes through hot melt adhesive and connects outside pipeline, connecting pipe main part both ends are equipped with the throat structure, the tip wall thickness of throat structure is the half of pipeline wall thickness, connecting pipe main part outside and inboard are equipped with outside ring channel and inside ring channel respectively, be equipped with the hot melt adhesive film in the inside ring channel, it has the hot melt powder to fill between inside ring channel and the inside ring channel, is equipped with the hot melt adhesive film in the outside ring channel.

Preferably, the number of the outer annular grooves is two, the outer annular grooves are symmetrically distributed, the width of the outer annular grooves is one tenth to one twelfth of the length of the connecting pipe body, and the distance between the outer annular grooves is one third to one fourth of the length of the connecting pipe body.

Preferably, the edge of the inner annular groove is located outside the outer annular groove.

Compared with the prior art, the utility model has the beneficial effects that: the leakage-resistant composite plastic pipe fitting utilizes the ductility of the hot melt adhesive film and the expansibility of the hot melt adhesive, so that the pipeline can not generate larger internal structural deformation when being bent, and the leakage-resistant capability of the pipeline is improved.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Referring to fig. 1-2, the present utility model provides a technical solution: the utility model provides an impervious composite plastic pipe fitting, includes connecting pipe main part 1, connecting pipe main part 1 passes through hot melt adhesive and connects outside pipeline, connecting pipe main part 1 both ends are equipped with throat structure 3, the tip wall thickness of throat structure 1 is the half of pipeline wall thickness, can be more convenient be connected with other pipelines, has improved the swiftly of connection, connecting pipe main part 1 outside and inboard are equipped with outside ring channel 2 and inside ring channel 4 respectively, the quantity of outside ring channel 2 is two, and the symmetric distribution, the width of outside ring channel 2 is the tenth to the twelve of connecting pipe main part 1 length, the distance between the outside ring channel 2 is the third to the quarter of connecting pipe main part 1, makes things convenient for connecting pipeline and pipeline on both sides to be connected, can not bring the effect of infiltration because of the bending of low angle the edge position of inside ring channel 4 is in the outside of outside ring channel 2, be equipped with hot melt adhesive film 6 in inside ring channel 4, it has hot melt powder 5 to fill between inside ring channel 6 and the inside ring channel 4, is equipped with hot melt adhesive film 2 in the outside ring channel 2, utilizes the expansion and the pipeline of hot melt adhesive to make the pipeline expansion and the ductility can not produce the impervious structure greatly when bending.

When in use: the pipeline that needs to be connected with connecting pipe main part 1 both sides are tailor the appropriate length, insert the pipeline that needs to be connected with the throat at connecting pipe main part 1 both ends, then carry out the angle bending that needs can, wherein symmetrical distribution's outside ring channel 2 carries out the hot melt with the pipeline respectively and is connected, inside hot melt adhesive film and hot melt adhesive have carried out good extension and inflation, have improved the impervious ability of pipeline, have satisfied the pipeline and have connected and the crooked needs of low-angle, have improved the operational environment of pipeline.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
