Abstract
Disclosed is an insulated joint for a pipeline. A long neck insulated flange is inlaid and sleeved in an specially shaped insulated sleeve and is connected and fixed through a locating ring. A primary insulated ring and a secondary insulated ring are respectively arranged between the long neck insulated flange and the specially shaped insulated sleeve and the long neck insulated flange and the locating ring. Internal insulation media are filled in an annular space formed by the long neck insulated flange and the specially shaped insulated sleeve. External insulation media are filled in an annular space between the long neck insulated flange and the locating ring. An inner surface and an outer surface of the long neck insulated flange are respectively provided with an insulation sleeve in a pressing mode. An insulated blocking ring is arranged between the long neck insulated flange and the locating ring. An outer insulated sleeve is arranged on an outer surface of the insulated joint.
Description
Technical field:
The utility model relates to a kind of pipe joint, particularly a kind of pipeline insulating joint.
Background technique:
At present, carry the pipeline of non-electrolyte (liquid phase or gas phase) normally to be embedded in underground with insulating joint in the industrial fields such as petrochemical industry, formed by short tube, left flange, right flange and connecting ring etc., internal surface at right flange scribbles epoxy resin, when media water-bearing, easily with the left and right flanges short circuit, lose the insulating property that require, only seal with seal ring in gap between connecting ring and right flange in addition, after long-time, seal ring is easily aging, lose sealability, underground water is easily invaded in the chamber and to be destroyed insulating properties, and counter-bending ability also a little less than.
The model utility content:
The purpose of this utility model just is to provide a kind of insulating property reliable, the pipe joint that counter-bending ability is strong---isolation connector for nonconductive medium pipe line.
Technical solution of the present utility model is; The long-neck insulated flange is nested in the allotype insulation cover, and is connected and fixed by positioning ring, is respectively arranged with primary insulation ring and secondary insulating ring between long-neck insulated flange and allotype insulation cover and positioning ring; Be filled with interior insulating matter in the annular space of long-neck insulated flange and the formation of allotype insulation cover, be filled with external insulation matter in the annular space between long-neck insulated flange and positioning ring.
Be suppressed with insulating bush on the inside and outside surface of long-neck insulated flange; Be provided with the insulation baffle ring between long-neck insulated flange and positioning ring; The outer surface of described insulating joint is provided with external insulation sleeve.
The utility model is simple in structure, novel in design, have insulating property reliable, good seal performance, the advantage that counter-bending ability is strong, improved the working life of insulating joint, guaranteed the safe transport of pipeline, the utility model is a kind of pipeline insulating joint that is applicable to the industrial field conveying non-conductive mediums such as petrochemical industry.
Description of drawings:
Below in conjunction with accompanying drawing and most preferred embodiment, content of the present utility model is further elaborated.
Fig. 1 is that main TV structure of the present utility model partly cuts open schematic diagram.
Embodiment:
with reference to accompanying drawing, the utility model is mainly by long-neck insulated flange 1, the compositions such as positioning ring 5 and allotype insulation cover 9, the outer surface of described insulating joint is provided with external insulation sleeve 3, long-neck insulated flange 1 is nested in allotype insulation cover 9, and be connected and fixed threadably by positioning ring 5, clamp once dead ring 8 at long-neck insulated flange 1 and 9, allotype insulation cover, in long-neck insulated flange 1 and location and clamped secondary insulating ring 11, be respectively arranged with a self sealing seal ring 10 in the both sides of primary insulation ring 8, to prevent that medium from infiltrating in the chamber, be filled with interior insulating matter 7 in the annular space that long-neck insulated flange 1 and allotype insulation cover 9 form, be filled with external insulation matter 12 in the annular space of 5 of long-neck insulated flange 1 and positioning rings, thereby insulating property have greatly been improved.Be suppressed with high hardness, high strength on long-neck insulated flange 1 inside and outside surface, certain flexible insulating bush 2 is arranged, further guaranteed the reliability of insulation, several zigzag fashion locating slots 13 of processing on long-neck insulated flange 1 are to improve peeling strength.For improving the counter-bending ability of insulating joint, be provided with insulation baffle ring 4 in the space of long-neck insulated flange 1 and positioning ring 5.In order to guarantee the tightness between retaining member, allotype insulation cover 9 has carried out again weldering fixed with 5 of positioning rings except being threaded, weld seam 6 is away from seal ring 10, reduce the impact of welding heat capacity on Sealing and insulating part quality, guaranteed the reliability of seal ring and insulating part.
The utility model makes its insulating properties, life-span and counter-bending ability all greatly improve than existing buried insulating joint owing to having had said structure.
