Technical field
The utility model relates to the linkage structure of pipeline, particularly relates to a kind of interface linkage structure of non-corrosive metal (NCM) pipeline.
Background technique
The interface shape of traditional inside lining anti-corrosive pipeline has flange join type, joint socket rubber sealing formula etc., and the flange connection all requires sealing material necessary anticorrosion and high temperature resistant when being connected with cushion rubber.More than the sealing means of two kinds of forms all have shortcomings such as sealing joint is tight, rigidity difference.
Summary of the invention
The technical problems to be solved in the utility model provides that a kind of sealing joint is tight, the interface linkage structure of the non-corrosive metal (NCM) pipeline of good rigidity.
The purpose of this utility model is achieved through the following technical solutions:
A kind of interface linkage structure of non-corrosive metal (NCM) pipeline, comprise metallic conduit and the plastics corrosion protective lining that is combined on the metal pipe internal wall, described non-corrosive metal (NCM) pipeline is divided into multistage, adjacent two sections non-corrosive metal (NCM) pipelines are plugged on together at jointing, outer periphery at the interface of pegging graft is equipped with the swagelok that is used for the sealed interface place, between the interface of swagelok and grafting, be formed with cavity, in cavity, be filled with the corrosion-resistant resin fillers.
Above-mentioned adjacent two sections non-corrosive metal (NCM) pipelines form socket and bellmouth respectively at jointing, and the external diameter of socket and the internal diameter of bellmouth adapt, and described adjacent two sections non-corrosive metal (NCM) pipelines are plugged on together by socket and bellmouth.
The another kind of mode of plug in structure is, in described adjacent two sections non-corrosive metal (NCM) pipelines, the outer periphery of one section jointing is equipped with the metal setting sleeve with certain-length therein, the external diameter of the internal diameter of metal setting sleeve and non-corrosive metal (NCM) pipeline adapts, one end of metal setting sleeve is welded on this section non-corrosive metal (NCM) pipeline, the other end extends certain-length to the direction away from interface vertically, and described adjacent two sections non-corrosive metal (NCM) pipelines are plugged on together by described metal setting sleeve.
Above-mentioned swagelok is made up of two taper members, the small-caliber end of each taper member is away from interface and seal welding is near the outer circumferential face of the non-corrosive metal (NCM) pipeline the interface respectively, and the heavy caliber end seal welding of two taper members together.
The interface linkage structure of non-corrosive metal (NCM) pipeline of the present utility model is plugged on adjacent two pipelines together earlier when connecting, and fills etch-proof resin fillers then between swagelok and interface, and two members with swagelok weld together at last.Because solder joint is away from the interface of non-corrosive metal (NCM) pipeline, so can not damage the plastics corrosion protective lining during welding, that is, realized the welding of composite anti-corrosion metallic conduit, simplified the fitting operation of pipeline; Simultaneously, between swagelok and interface, be filled with etch-proof resin fillers, thereby strengthened the leakproofness of interface.
Description of drawings
Fig. 1 is an embodiment's of a non-corrosive metal (NCM) pipe joint linkage structure of the present utility model sectional drawing;
Fig. 2 is another embodiment's of a non-corrosive metal (NCM) pipe joint linkage structure of the present utility model sectional drawing.
Embodiment
Be elaborated below in conjunction with the interface linkage structure of accompanying drawing to non-corrosive metal (NCM) pipeline of the present utility model.
Fig. 1 is an embodiment of non-corrosive metal (NCM) pipe joint linkage structure of the present utility model.As shown in Figure 1, the interface linkage structure of described non-corrosive metal (NCM) pipeline comprises: metallic conduit 10 and the plastics corrosion protective lining 11 that is combined on metallic conduit 10 inwalls, adjacent two sections non-corrosive metal (NCM) pipelines form socket 15 and bellmouth 14 respectively at jointing, the internal diameter of the external diameter of socket 15 and bellmouth 14 adapts, and two neighboring sections non-corrosive metal (NCM) pipeline is plugged on together by socket 15 and bellmouth 14.Outer periphery at the interface of pegging graft is equipped with the swagelok 12 that is used for the sealed interface place, described swagelok 12 is made up of two taper members, the small-caliber end of each taper member is away from interface and seal welding is near the outer circumferential face of the non-corrosive metal (NCM) pipeline the interface respectively, and the heavy caliber end seal welding of two taper members together.Between the interface of swagelok 12 and grafting, be formed with cavity, in cavity, be filled with corrosion-resistant resin fillers 13.
Figure 2 shows that another embodiment's the sectional drawing of the interface linkage structure of non-corrosive metal (NCM) pipeline of the present utility model.This embodiment is that with first embodiment's difference the inserting mode of adjacent two sections anti-corrosion pipelines is different.As shown in Figure 2, in adjacent two sections non-corrosive metal (NCM) pipelines, the jointing outer periphery of the metallic conduit on right side shown in the figure is equipped with the metal setting sleeve 16 with certain-length, the external diameter of the internal diameter of metal setting sleeve 16 and non-corrosive metal (NCM) pipeline adapts, one end of metal setting sleeve 16 is welded on the non-corrosive metal (NCM) pipeline on right side, the other end extends certain-length to the direction away from interface vertically, and two neighboring sections non-corrosive metal (NCM) pipeline is plugged on together by metal setting sleeve 16.
In two above-mentioned embodiments, described metallic conduit is identical with the material of metal joint sleeve pipe, is steel.Certainly, metallic conduit and metal joint sleeve pipe also can be other metal materials.Plastics corrosion protective lining 11 can be polyethylene (PE), crosslinked polyethylene polyolefin (PO) such as (PE-X), also can be teflon.Resin fillers 13 can be epoxy resin or unsaturated polyester resin.
