Background technique
Heat distribution pipeline causes that because of the variation of fed sheet of a media temperature or pressure pipeline produces end thrust and distortion, for guaranteeing the safe operation of pipe network, necessary pipe line compensating device is set in pipe network under the normal conditions absorbs end thrust and compensation distortion.At present, being applied to more in pipe network is the whirl compensator that a kind of compensation rate is large, absorptivity is strong.The whirl compensator of prior art generally seals by the elastic reaction of Sealing self, during, sealing part abrasion too high when pressure medium in the pipeline, leaks the sealing in the time of can't guaranteeing high pressure unavoidably; On the other hand, when carry be the stronger high temperature media of corrosivity the time, the adapter of whirl compensator and inner tube wall directly and the stronger high temperature media of corrosivity contact, very easily corrode and wear and tear, so that the whirl compensator of prior art is shorter working life.
Summary of the invention
The utility model is for the deficiencies in the prior art, propose a kind of simple in structure, energy automatic compensation sealing gap, significantly reduce sealing part abrasion, significantly reduce adapter and inner tube wall corrosion and the wearing and tearing of whirl compensator, effectively prolong compensator wear-resisting, the corrosion resistance high-pressure rotary compensator in working life.
The utility model is achieved through the following technical solutions technical goal.
Wear-resisting, corrosion resistance high-pressure rotary compensator, mainly by the outer sleeve with end flange, an end stretch into inner tube in the outer sleeve, be enclosed within inner tube sealing gland outer and that be connected by bolt assembly with the end flange of outer sleeve, the adapter that is fixedly connected on the outer sleeve left end forms; Described inner tube left end outer wall is provided with the annular outer platform, the internal surface of casing middle part is provided with annular inner convex platform outside, annular outer lug boss is equipped with Sealing in the Seal cage between annular outer platform and the outer sleeve internal surface annular inner convex platform on inner pipe on the described inner tube between adapter and outer sleeve internal surface annular inner convex platform; Described sealing gland suit on inner pipe and insert the right-hand member of outer sleeve and the stuffing box packing that is installed between outer wall of inner tube, the outer sleeve right-hand member hole offsets; The internal surface of annular outer platform is provided with annular groove and setting-in ball and consists of to roll with outer wall of inner tube and cooperate on inner pipe; Its improvements are: be fixedly connected with the latticed net of thin-walled at described adapter, inner tube wall, the high-abrasive material of filling in the space of described net, bond; Be provided with metallic packing ring between annular outer lug boss and the Sealing on the described inner tube; The face that contacts with stuffing box packing on the described sealing gland is conical surface, and the larger diameter end of this conical surface is towards stuffing box packing; Between described sealing gland end flange right side and bolt assembly right-hand member tightening nut, be provided with spring.
The further technological scheme of the utility model is: described spring is butterfly spring; Described high-abrasive material is wear-resistant ceramic mud.
The utility model compared with prior art has following good effect:
1. when the high temperature media that corrosivity is stronger is flowed through adapter, inner tube, only contact with the inwall of high-abrasive material formation in the net, do not contact with adapter, inner tube wall, the inwall that the high-abrasive material that only weares and teares forms, and the inwall that high-abrasive material forms is very wear-resisting, also corrosion-resistant, so significant prolongation is taken over, inner tube working life, whirl compensator prolongs more than the twice working life.
2. be provided with metallic packing ring between annular outer platform and the Sealing on inner pipe, compensator in use, on the inner tube annular outer lug boss directly and the metal sealing loop contacts, like this, mainly by the metallic packing ring taking up wear, and metallic packing ring is more wear-resisting.
3. between sealing gland end flange right side and bolt assembly right-hand member tightening nut, be provided with spring, can be behind sealing part abrasion auto-compensation, guarantee sealing effect.
4. the face that contacts with stuffing box packing on the sealing gland is conical surface, and stuffing box packing is subject to axially and lateral extrusion simultaneously in compaction process like this, so that outer wall of inner tube is tightly embraced in stuffing box packing, improves sealing reliability, improves compensator and compresses ability.
