Abstract
The invention discloses an anti-fatigue GIS corrugated pipe compensator. The anti-fatigue GIS corrugated pipe compensator comprises a flange, a connecting pipe, a corrugated pipe and a protecting bush. The end face of the flange is provided with a sealing groove. The corrugated pipe comprises at least two layers of thin-wall corrugated pipe bodies which are sleeved together. A wear-resistant coating is arranged between the thin-wall corrugated pipe bodies. The corrugated pipe is sleeved with the protecting bush. The inner wall of the protecting bush makes contact with wave crests of the corrugated pipe. One end of the protecting bush is fixedly connected to the inner end face of the flange. Through further improvement, the wear-resistant coating is changed into a thermal spraying wear-resistant coating which is a wear-resistant alloy coating; the sealing groove of the flange is changed into a step-like combined sealing groove; and an axial gap between the end of the connecting pipe and the corrugated pipe is filled with silica gel. According to the anti-fatigue GIS corrugated pipe compensator, little wear occurs between the thin-wall corrugated pipe bodies. The corrugated pipe compensator is good in sealing performance and capable of effectively preventing fatigue failure of the two ends of the corrugated pipe, and the service life of the compensator is remarkably prolonged.
Description
Technical field
The present invention relates to the compensation device of pipeline, be specifically related to the GIS corrugated expansion joint used by a kind of High-voltage Switchgear Industry.
Background technology
GIS(Gas Insulated Switchgear Cubicle Gas-Insulated Switchgear) corrugated expansion joint includes flange, corrugated tube, adapter, corrugated tube is pressed into multilayer corrugated pipe by multi-layered sheet, to play compensating action.GIS corrugated expansion joint is when use compensates, constantly carry out relative motion between multilayer corrugated pipe, cause abrasion due to phase mutual friction between adjacent corrugations pipe, thin plate may be caused to make corrugated tube worn out, cause corrugated tube to lose efficacy, cause GIS corrugated expansion joint shorter for service life；On the other hand, corrugated tube is easy to occur to destroy under the effect of alternate load, and the fracture of corrugated tube usually occurs between the first ripple and the second ripple, and compensator is short for service life.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, design one and can effectively stop fatigue failure, the mutual abrasion between corrugated tube, the notable Anti-fatigue type GIS corrugated expansion joint extending compensator service life can be substantially reduced.
The present invention is achieved through the following technical solutions technical goal.
Anti-fatigue type GIS corrugated expansion joint, including flange, adapter, corrugated tube；Described end face of flange is provided with seal groove；Described corrugated tube includes that at least two-layer is linked in thin-wall corrugated tube together；It thes improvement is that: described Anti-fatigue type GIS corrugated expansion joint also includes sheath；It is provided with wear-resistant coating between described thin-wall corrugated tube；Described sheath is set on corrugated tube, and its inwall contacts with corrugated tube crest, and one end is fixedly connected on flange inner face.
In said structure, described wear-resistant coating is thermal spraying wear-resistant coating.
In said structure, described thermal spraying wear-resistant coating is coated with wear-resisting alloy.
In said structure, described flange sealing trough is staged combination sealing groove.
In said structure, filling gel in axial gap between described pipe ends and corrugated tube.
The present invention compared with prior art, has the positive effect that:
1. it is provided with wear-resistant coating between thin-wall corrugated tube, so, substantially reduces the mutual abrasion between corrugated tube, notable extend compensator service life.
2. spacing sheath is increased at corrugated tube two ends, the radial deformation of corrugated tube two-end part can be substantially reduced, reduce radial stress, this deformation is allowed to transfer to the centre position that pliability compares the corrugated tube of concentration, thus effectively stop the fatigue failure of corrugated tube two-end part, prolongation compensator service life further.
3. flange sealing trough is staged combination sealing groove, during use, lays combination sealing pad in this seal groove, significantly improves sealing property when corrugated expansion joint uses.
4. filling gel in axial gap between pipe ends and corrugated tube, it is to avoid take over during using and directly contact with corrugated tube, play the effect protecting corrugated tube..
Fig. 1 is present configuration schematic diagram.
Fig. 2 is I enlarged schematic partial view in Fig. 1.
Fig. 3 is II enlarged schematic partial view in Fig. 2.
