CN2474879Y - Aluminium plastic composite pipe plastic sealing pipe joint - Google Patents

Abstract

The device relates to a pipeline connector comprising a pipe fitting body, a sealing ring, a snap ring, and a stop nut, wherein the core pipe of the pipe fitting body is provided with the sealing ring which is outwardly sheathed with the snap ring which is outwardly sheathed with the stop nut, and a sealing adhesion glue line is provided between the connector core pipe and the pipe fitting to be connected, then the nut is tightened after inserting the connected pipe to constitute the whole pipe connector into an integral. The utility model has the advantages of simple structure, easy assembling and using, having the most distinguishable characteristics of structural durability, non-water leakage, wide application scope, and is applicable to various connector pipe fittings.

Description

Aluminium-plastic composite pipe plastic cement sealed pipe joint

The utility model relates to a kind of pipe coupling, is adapted at using when various flexible pipes connect.

At present, the method that in aluminium-plastic composite pipe connects, mostly adopts the mechanical splice fitting to fitting to connect, the joint pipe fitting is connected the end the inside and is joint core pipe, after connecting tube inserts from the outside, being with the pressure pipe fitting by the jointed tubular workpieces outside, produce flow after the pressing, reach pipeline and connect purpose, its deficiency is that sealing effect is poor, and time one length has water leakage phenomenon to take place.

For solving the deficiency that above pipe fitting connects sealing, the purpose of this utility model provides a kind of aluminium-plastic composite pipe plastic cement sealed pipe joint, adopts the middle structure of plastic cement filling of utilizing of joint to reach the purpose of robust sealed.

Structural design of the present utility model is achieved in that sealed pipe joint is made up of pipe fitting, seal ring, trip ring and lock nut, its structure is that pipe fitting one end center is a joint core pipe, on the joint core pipe seal ring is housed, joint core pipe overcoat forms outside thread, joint core tube outside is with trip ring, the trip ring outside is a lock nut, be added with the sealer adhesive-layer between the aluminium-plastic composite pipe at joint core pipe and by being connect, lock nut is after screwing on the outside thread, and the integral sealing pipe joint is become one (as shown in drawings).

The utility model advantage: simple in structure, easy to install, maximum characteristics are good seal performance, and are durable in use, water-tight, and applied range is adapted at using on the various terminal pipe fitting.

The utility model detailed structure is provided by following examples and accompanying drawing.

Fig. 1 is an aluminium-plastic composite pipe plastic cement sealed pipe joint shape assumption diagram.

Fig. 2 is aluminium-plastic composite pipe plastic cement sealed pipe joint parts sectional drawings.

Its structure as shown in drawings, joint pipe fitting 1 is a pipe fitting, the two ends symmetry, one end center is a joint core pipe 2, and core pipe overcoat is a screw thread, and seal ring 3 is housed on the core pipe, 4 is trip ring, and 5 is lock nut, and 6 is by jointed tubular workpieces, when being inserted on the joint core pipe 2 by jointed tubular workpieces 6, be added with sealer on it, this glue is the modified silane sealer, the outside is with trip ring 4, and nut is screwed on the outside thread, is taken over and sealed pipe joint connects and is one, intensity is good, good seal.
