Abstract
The utility model discloses a high-temperature heat-conduction-oil dual-seal-type rotating connector which comprises a shell 2, a bulb tube 3, an oilless bearing 4, an auxiliary seal asbestos cushion 5, an antimony-impregnated graphite plane sealing ring 7, an antimony impregnated graphite sphere surface sealing ring 8 and a metal ripple compensator 9. The high-temperature heat-conduction-oil dual-seal-type rotating connector is characterized in that the antimony impregnated graphite sphere surface sealing ring 8 is arranged at the bottom of the shell 2 and is sealed in a friction mode; the bulb tube 3 is arranged outside the antimony impregnated graphite sphere surface sealing ring 8 and is sealed in a spherical friction mode; the antimony-impregnated graphite plane sealing ring 7 is arranged on the outer end surface of the bulb tube 3 and is sealed in a plane friction mode; the metal ripple compensator 9 is sealed with the antimony-impregnated graphite plane sealing ring 7 in a plane fraction mode. The oilless bearing 4 is arranged between the inner wall of an elbow 1 and the external diameter of the bulb tube 3, the auxiliary seal asbestos cushion 5 and the metal ripple compensator 9 are tightly pressed and sealed and integrated by bolts through the elbow 1. The high-temperature heat-conduction-oil dual-seal-type rotating connector has the advantages of being simple in structure, heat resisting, wear-proof and good in sealing performance and dust-proof performance.
Description
Technical field
The utility model relates to a kind of swivel joint, particularly a kind of high temperature heat conductive oil double seal type swivel joint.
Background technique
At carton, food machinery industry; often can improve with a kind of conduction oil the surface temperature of dryer roll; basically all be to adopt common whirligig to be solved; this common whirligig since for a long time high temperature so that the impurity of the impact sealings such as carbonization appears in hot oil medium inside; thereby easy to wear, heat-resisting quantity is poor, working life is short, evaporating, emitting, dripping or leaking of liquid or gas occurs often, since oil impregnate serious; the surface is the absorption dust easily, the attractive in appearance and environmental hygiene of the equipment that affects, change frequent etc.
Summary of the invention
The utility model is for above-mentioned the deficiencies in the prior art, and a kind of simple in structure, high temperature resistant, wear-resistant, sealing and the good swivel joint of anti-dust performance are provided.
The technical solution of the utility model is: comprising: elbow 1, housing 2, bulb 3, oilless bearing 4, auxiliary seal asbestos packing 5, soak antimony graphite plane seal ring 7, soak antimony graphite spherical seal ring 8, metal corrugation compensator 9, spring 10, adjusting nut 11, spline hole 12, it is characterized in that: described spline hole 12 is on housing 2, soak antimony graphite spherical seal ring 8 and be positioned at the bottom friction sealing of housing 2, bulb 3 is installed in that to soak antimony graphite spherical seal ring 8 outside spheres friction sealed, soak antimony graphite plane seal ring 7 and be contained in the exterior edge face planar friction sealing of bulb 3, spring 10 is installed in the centre of metal corrugation compensator 9 external diameters and adjusting nut 11, metal corrugation compensator 9 with soak the sealing of antimony graphite plane seal ring 7 planar frictions, oilless bearing 4 is contained in elbow 1 inwall, between the external diameter of bulb 3, with screw by elbow 1 auxiliary seal asbestos packing 5 and metal corrugation compensator 9 press seals and consist of an integral body.
The utility model advantageous effect: 1, good seal performance, can drive bulb during the dryer roll rotation is rotated, when medium enters through oilless bearing from the elbow, under the suppressing of metal corrugation compensator, soak antimony graphite plane seal ring and metal corrugation compensator bulb and form the friction sealed pair of first Double End, to form the second Double End friction sealed with soaking antimony graphite spherical seal ring and housing for bulb, after soaking the wearing and tearing of antimony graphite annulus, the wavy metal device can provide sealing required end-face compensate pressure at any time, finishes medium by quiet course of conveying to moving.2, anti-dust performance is good, when having certain impurity to enter the first sealing, even destroyed the first sealing, causes seepage, also can larger particulate blockage outside the second sealing, reach the purpose to dryer roll safe transport medium.3, soak antimony graphite plane seal ring and soak antimony graphite spherical seal ring owing to used, make this swivel joint high temperature resistant, wear-resistant.200 rev/mins of the utility model maximum speeds, 280 degrees centigrade of maximum temperatures, maximum pressure is 1.8MPa, is applicable to the media such as high temperature heat conductive oil, superheated vapor.
