Abstract
The invention relates to a redundant connector for a nylon pipeline. The redundant connector comprises clamp connectors, a connecting sleeve, a telescopic sleeve, end covers, thrust rings, sealing rings, fastening bolts and positioning bolts. According to the redundant connector, by means of clearance fit of an outer diameter of the telescopic sleeve and a medium-diameter stepped hole of the connecting sleeve, the telescopic sleeve can axially slide in the connecting sleeve, and radial sealing is realized through the sealing rings during sliding; by means of axial positioning of two end surfaces and of the thrust rings, end cover surfaces and a connection surface of the medium-diameter stepped hole and a small-diameter stepped hole in the connecting sleeve, the telescopic sleeve only performs limited axial sliding in the connecting sleeve; meanwhile, a plurality of the positioning bolts are used for performing constraint positioning on the circumferential position between the clamp connectors and the connecting sleeve. The redundant connector is mounted in a long-distance pipeline, and the nylon pipeline has a redundant part, so that normal operating of the pipeline is not influenced. The redundant connector has the advantages of simple structure, convenience in installation, stable connection and sealing, and free stretching and retracting.

The inside of described adapter sleeve is provided with large footpath, central diameter and three grades of step holes of path successively, and is provided with at least a circular groove in the central diameter step hole;
External diameter one end of described adapter sleeve is provided with flange, and flange is provided with some uniform bolts hole, and the external diameter the other end is consistent with the external diameter of nylon pipeline, and also is provided with the ring-type draw-in groove on the external diameter;
Described telescopic tube is straight-tube shape, its external diameter one splaying is engaged in the central diameter step hole of adapter sleeve, the stage casing falls in the large footpath step hole of adapter sleeve, the other end stretches out outside the adapter sleeve, and the external diameter of external part is provided with the ring-type draw-in groove, and the stage casing external diameter that falls in the step hole of the large footpath of adapter sleeve is provided with the thrust groove;
Described end cap is provided with some bolts hole, and its flange by some clamping bolts and adapter sleeve one end fixes, and is Spielpassung between the external diameter of the endoporus of end cap and telescopic tube;
Described thrust ring places in the thrust groove on the external diameter of telescopic tube middle part, is Spielpassung between the large footpath step hole in the external diameter of thrust ring and the adapter sleeve;
Described seal ring is the Y type, and it places between the external diameter of seal groove in the adapter sleeve middle bench hole and telescopic tube;
Described holding down bolt is many, and an end of every bolt is by two nuts and tight on the flange and end cap of adapter sleeve, and the other end passes many positioning holes of thimble connector outside, and the nut anti-falling of screwing on.
The present invention can endwisely slip telescopic tube by the Spielpassung between telescopic tube one end external diameter and the adapter sleeve central diameter step hole in adapter sleeve, realize radial seal by seal ring in the slip; And by the central diameter step hole in thrust ring both ends of the surface and end cap face and the adapter sleeve and the axially locating between the junction surface between the path step hole, make telescopic tube in adapter sleeve, only do limited moving axially; Meanwhile also by many holding down bolts the circumferential position between thimble connector and the adapter sleeve is implemented the constraint location.The present invention is installed in long distance pipeline, and nylon pipeline exists redundant and does not affect the normal operation of pipeline.
That the present invention has is simple in structure, easy for installation, connect that sealing is stable, retractile advantage.
