Abstract

The utility model relates to an offset-type anti-leak plastic pipe fitting of the plastic pipe fitting in the drainage works, which is characterized in that a water retaining ring is arranged in the outlet of a plastic pipe as the inner retaining ring of the outlet, and the upper end of the inner hole of plastic pipe material is matched with the outer cone of the inner retaining ring of the outlet of the plastic pipe fitting to form an annular seal ring. Adhesive is coated when the plastic pipe fitting and the pipe material are installed, and the adhesive which is aggregated between the upper end surface of the pipe material and the upper end surface of the inner retaining of the water outlet of the pipe fitting forms the adhesive seal ring after solidifying. The utility model has the advantages of reasonable structural design, and installation security, solving the effluent seepage problem of the joint for pipe fittings.

Description

Offset-type anti-leak plastic pipe fitting

A kind of plastic pipe that is used for drainage works---interpolation type leakproof plastic pipe.

At present, plastic pipe is extensive use in drainage works, and plastic pipe and plastic pipe are bonding with adhesive when mounted, usually exist the problem of infiltration, be difficult to guarantee the quality of construction, influence sanitation of environment, the application life of also having reduced building simultaneously.

The purpose of the utility model interpolation type leakproof plastic pipe is to solve uses plastic pipe and plastic pipe that the problem of infiltration is installed in the drainage works, guarantee construction quality, improves the application life of building.

The utility model interpolation type leakproof plastic pipe content Description:

The utility model interpolation type leakproof plastic pipe, it is characterized in that it being that a retaining ring is set is the delivery port inner shield ring in plastic pipe delivery port body, the hole end surface upper end cooperates with plastic pipe retaining ring male cone (strobilus masculinus) in the plastic pipe, form an O-ring seal, bonding surface application of adhesive when plastic pipe and plastic pipe are installed, insert in the plastic pipe process at plastic pipe, the adhesive of assembling in the upper surface and the plastic pipe retaining ring upper surface of plastic pipe solidifies the back and forms the adhesive seal circle.

The utility model interpolation type leakproof plastic pipe reasonable in design is installed safe and reliablely, has solved the effluent seepage problem of pipe fitting joint in the drainage works, can guarantee construction quality, improves the application life of building, has improved sanitation of environment.

Embodiment:

Accompanying drawing is an interpolation type leakproof plastic pipe delivery port structure chart.

It is delivery port inner shield ring (3) that a retaining ring is set in plastic pipe delivery port body (1), can be in drainage procedure as contrary road device, sewage can not be flow backwards, (2) be plastic pipe, plastic pipe and plastic pipe are installed together, the hole end surface upper end cooperates formation O-ring seal (4) in the plastic pipe with plastic pipe delivery port inner shield ring male cone (strobilus masculinus), bonding surface application of adhesive when plastic pipe and plastic pipe are installed, plastic pipe inserts in the plastic pipe process, adhesive in plastic pipe upper surface and the gathering of plastic pipe delivery port inner shield ring upper surface solidifies back formation sealing ring (5), even these two sealing rings cause under the situation of pipe blocking at sewage in the sewer process, sewage can not solve leakage problems from the pipe fitting joint infiltration.

Claims

1, a kind of interpolation type leakproof plastic pipe that is used for drainage works is characterized in that it being that a retaining ring is set is the delivery port inner shield ring in plastic pipe delivery port body; Cooperates O-ring seal of formation in the plastic pipe on the hole end surface with plastic pipe delivery port inner shield ring male cone (strobilus masculinus); Bonding surface application of adhesive when plastic pipe and plastic pipe are installed inserts in the plastic pipe process at plastic pipe, and the adhesive of assembling in the upper surface and the plastic pipe delivery port inner shield ring upper surface of plastic pipe solidifies the back and forms the adhesive seal circle.
