Abstract

The utility model discloses a kind of linkage structure of pipe fittings, comprise pipeline, seal ring and pipe fittings, described pipeline is connected and sealed by seal ring and pipe fittings, described pipe fittings comprises pipe fitting matrix, the outer wall of described pipe fitting matrix is provided with zinc coat or coating layer, described pipe fitting matrix inwall is connected to the plastic layer without joint core by heat-fusing glue layer, and described plastic layer is provided with the carrier contacted with pipe end.The utility model solve painting/line plastic-steel tube inwall plastic layer partially thick time difficult problem is installed, under supporting seal ring effect, the sealing of pipe end is better than traditional pipe fitting.

Description

A kind of linkage structure of pipe fittings
Technical field
The utility model relates to lining plastic pipe production technical field, particularly a kind of linkage structure of pipe fittings.
Background technique
Lining plastic pipe be on the basis of the zinc-plated pipe fitting of tradition for meeting market and environmental requirement and the novel product of upgrading, there is many advantages.As shown in Figure 1, the lining plastic pipe sold in the market, the plastic lining layer of inwall has a joint core 9 at pipe port place.And the Main Function of joint core is exactly pipe fitting and steel pipe nozzle is connected to form sealing, prevent from pipe end from contacting water to corrode, but a lot of problems can be run in the operation of reality, partially thick, the non-chamfering of such as painting/line plastic-steel tube inwall plastic layer and when connecting the necessary of similar spigot, foreign side's pipe plug and so on, all cannot carry out connection, directly affect quality and the phase of friendship of engineering.Solve this type of existing problems, need a kind of novel lining plastic pipe of exploitation and tube fit to meet usage requirement.
Number of patent application 201210263622.4, patent name is " a kind of external galvanized layer plastic-lined composite pipe production technology and composite pipe ", it discloses a kind of composite pipe, comprise steel pipe matrix, the outer wall of described steel pipe matrix is provided with zinc coat, the inwall of described steel pipe matrix is lined with plastic layer, described plastic layer is joint core plastic layer, it is partially thick that this joint core plastic layer can run into the above-mentioned steel pipe inner wall plastic layer mentioned in practical operation, non-chamfering and connect similar spigot, the necessary of foreign side's pipe plug and so on cannot the problem of connection, therefore need to improve.
Model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of linkage structure of pipe fittings.
The technical solution adopted in the utility model is as follows:
A kind of linkage structure of pipe fittings, comprise pipeline, seal ring and pipe fittings, described pipeline is connected and sealed by seal ring and pipe fittings, described pipe fittings comprises pipe fitting matrix, the outer wall of described pipe fitting matrix is provided with zinc coat or coating layer, and described pipe fitting matrix inwall is connected to plastic layer by heat-fusing glue layer.
Described plastic layer is without joint core, and is provided with the carrier contacted with pipe end.
The utility model improves for the joint core that has of prior art, eliminates bell and spigot joint, and the carrier arranged by plastic layer is contacted with pipe end, then fitted seal circle realizes connecting.
Compared with prior art, the beneficial effect that the utility model has: can connect with the necessary of similar spigot, foreign side's pipe plug and so on, thoroughly solve painting/line plastic-steel tube inwall plastic layer partially thick time difficult problem is installed, under supporting seal ring effect, the sealing of pipe end is better than traditional pipe fitting.
Accompanying drawing explanation
Fig. 1: the structural representation of conventional pipelines accessory;
Fig. 2: the structural representation of the utility model pipe fittings;
Fig. 3: pipe fittings linkage structure schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 2, a kind of pipe fittings, comprise pipe fitting matrix 2, the outer wall of described pipe fitting matrix 2 is provided with zinc coat 1, described pipe fitting matrix 2 inwall is connected to the plastic layer 4 without joint core by heat-fusing glue layer 3, and described plastic layer 4 is provided with the carrier 5 contacted with pipe end.
As shown in Figure 3, a kind of linkage structure of pipe fittings, comprises pipe fittings 6, and it is four-way pipe fitting, and described pipe fittings 6 one end is connected with the port of pipeline 8 by seal ring 7, and the port of described pipeline 8 contacts with carrier 5.
