Abstract

The invention relates to a steel-plastic conversion connecting structure which comprises a steel inner pressing ring and a PE sleeve pressed on the steel inner pressing ring in a sleeving mode. The outer side of the steel inner pressing ring is provided with a plurality of barb structures which are clamped on the inner surface of the PE sleeve. An outer pressing ring is arranged on the outer surface of the PE sleeve, and the PE sleeve is clamped between the steel inner pressing ring and the outer pressing ring. The steel outer pressing ring is also pressed on the PE sleeve in a sleeving mode, so that the PE sleeve is made to contract to be combined with the inner pressing ring more tightly. After the adoption of the structure, the barb structures enable the PE sleeve to be directly clamped on the steel inner pressing ring, and the PE sleeve cannot retract and is prevented from falling off, so that safety of fuel gas conveying is guaranteed; resources are saved, the service life is long, and unnecessary losses are reduced.

Description

Conversion linkage structure moulded by steel
Technical field
The present invention relates to a kind of linkage structure in fuel gas transmission equipment technical field, especially relate to a kind of steel and mould conversion linkage structure.
Background technique
At present, combustion gas has been requisite life day estovers during people live, and combustion gas enters in huge numbers of families by pipeline, these gas pipelines are generally be embedded in underground, and existing city gas transmission and distribution pipeline generally adopts steel pipe or adopts PE pipe, fastener for connection adopts electric welding to connect, intensity is good, and reliability is high, but complex process, periodically long, increase cost; PE pipe adopts electric smelting or hot-melt adhesive paste, and technique is simple, and periodically short, cost is low, but is limited to material own, and safety coefficient is not high; The PE valve of PE pipeline use simultaneously, due to the impact by factors such as temperature, reliability is poor, so in order to the reliability that ensures fuel gas transmission and Security, outside being exposed to or important occasion should adopt steel pipe, the valve that blocks needs to adopt and more insures safe steel valve, and PE plastic pipe and steel pipe, connection between valve just often become the technological difficulties needing to capture.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind of connection reliably can not comes off and ensure that conversion linkage structure moulded by the steel of the safety of fuel gas transmission.
The present invention solves the technological scheme that its technical problem takes: conversion linkage structure moulded by a kind of steel, comprise trim ring and cover in steel and be pressed in PE sleeve in steel on trim ring, in described steel, the outside of trim ring is provided with some barb structure, and described barb structure is stuck in the internal surface of PE sleeve.
Concrete further, in described steel, the outside of trim ring is provided with the groove of annular, and in described groove, be provided with seal ring, described seal ring contacts with the internal surface of PE sleeve.
Concrete further, the outer surface of described PE sleeve is provided with outer trim ring, and in described steel, PE sleeve is clipped in the middle by trim ring and outer trim ring.
The invention has the beneficial effects as follows: after have employed said structure, by barb structure, PE sleeve is directly stuck in steel on trim ring, can not falls back, prevent from coming off, ensure the Security of fuel gas transmission, saving resource, long service life, reduces unnecessary loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structure for amplifying schematic diagram of part A in Fig. 1.
In figure: 1, trim ring in steel; 2, PE sleeve; 3, outer trim ring; 4, barb structure; 5, groove; 6, seal ring.
Embodiment
Below in conjunction with accompanying drawing, the present invention is explained in detail.
Conversion linkage structure moulded by a kind of steel as depicted in figs. 1 and 2, comprise the PE sleeve 2 that in steel, trim ring 1 and cover are pressed in steel on trim ring 1, in described steel, the outside of trim ring 1 is provided with some barb structure 4, and described barb structure 4 is stuck in the internal surface of PE sleeve 2; In described steel, the outside of trim ring 1 is provided with the groove 5 of annular, and in described groove 5, be provided with seal ring 6, described seal ring 6 contacts with the internal surface of PE sleeve 2; The outer surface of described PE sleeve 2 is provided with outer trim ring 3, and in described steel, PE sleeve 2 is clipped in the middle by trim ring 1 and outer trim ring 3.
When installing, inserted by trim ring in steel 1 in PE sleeve 2, in steel, the barb structure 4 of trim ring 1 thrusts PE sleeve 2 internal surface, realization can not fall back, and compresses PE sleeve 2 by outer trim ring 3, improves its sealability, by the setting of seal ring 6 and groove 5, also ensure that its sealability.After installation, good seal performance, without revealing and can improving working life, there will not be PE sleeve 2 obscission, reduces unnecessary loss.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
