The utility model has the advantages of relatively big compensation ability, no corrosion, convenient maintenance, convenient replacement and convenient sealing, and can be widely applied to the conveying pipelines of oilfield, chemical engineering, power generation and shipbuilding coast environment.
Description
(1) technical field
The utility model relates to the articulating device of liquid, gas transmission pipeline, particularly relates to a kind of spherical linkage that flexibly connects as high temperature high pressure liquid, gas delivery pipeline.
(2) background technique
The external application of macrotype spherical hinge in industry starts from earlier 1900s, is widely used on the transfer line.Its size is many in 4-54 inch scope, the operating temperature of medium≤350 ℃, and medium is at working pressure≤5.5Mpa, 15-33 ° of spherical linkage flex angle.The macrotype spherical hinge mostly is four kinds of bayonet types, screw bolt-type, helical, injection type.Domestic the macrotype spherical hinge is called spherical compensator, brings into use the seventies in twentieth century.Owing to have understanding mistaken ideas such as " easily leak, leak gas, need to strengthen maintenance ", thereby the application at home of macrotype spherical hinge be restricted.Regulation among China metallurgy industry standard YB/T029-92 " universal spherical compensator technical specifications ", spherical compensator " is applicable on the heat distribution pipeline of hot water, steam, hot gas; the operating temperature of medium≤300 ℃ that nominal pressure≤1.6Mpa is used to compensate expanding with heat and contract with cold of heat distribution pipeline ".Standard is also stipulated, 30 ° of the maximum flex cone angles of spherical compensator.At present, the spherical compensator maximum working (operation) pressure (MWP) of domestic production is 2.5Mpa.It is widely used in fields such as oil, chemical industry, generating, manufacturing, river course mediation, is used for compensation pipes because of expanding with heat and contract with cold, and with the displacement that pipeline connection device sinking inclination, earthquake etc. cause, eliminates the failing stress that is produced by these displacements.
(3) summary of the invention
The technical problems to be solved in the utility model, provide a kind of novel ball compensator that also can be convenient for changing sealing than the large compensation ability that has, can be operated in temperature height (≤500 °), pressure height (≤8.0Mpa), 40 ° of maximum flex cone angles, medium is a saturated vapour, some product works in the seashore surrounding environment, needs to eliminate because of factors such as sea wind, wave cause its pipeline of carrying liquid or gas medium to produce a kind of spherical linkage of the complicated environmental condition of displacement and stress.
The technological scheme that adopts is:
A kind of spherical linkage comprises spheroid, ball seat flange, ball cover flange alive, two pipeline adpting flanges, seal washer and stuffing box packing.Described ball seat flange and ball cover flange alive is sleeved on the spherical portion of spheroid, pass through screw rod, nut, spring washer is fastening with ball seat flange and ball cover flange alive, ball seat flange that tightens together and ball cover flange alive and spheroid are rotationally connected, be provided with circular pit at its ball cover flange alive and the spheroid place of being rotationally connected, stuffing box packing is filled in the pit, two flange junction surface places of ball seat flange and ball cover flange alive, flanged surface at its ball cover flange alive is provided with annular groove, the flanged surface of corresponding ball seat flange is provided with annular boss, seal washer is pressed in the described groove, two pipeline adpting flanges are fixedly connected on the distolateral of spheroid and ball seat flange respectively, and and spheroid, the ball seat flange is fixed as one, and constitutes spherical linkage.
Above-mentioned ball seat flange and ball cover loose flange are equipped with the concave spherical surface that matches with spheroid, and are rotatably assorted with concave spherical surface and spheroid, and the maximum flex cone angle is 40 ° in relative rotation.
Above-mentioned stuffing box packing is the numb packing through mineral oil and plumbago processing, and seal washer is the rubber asbestos packing.
The utility model has the advantages that: the macrotype spherical hinge has and takes up room for a short time, and multi-directionally rotates flexibly, and it is strong to bear vibration ability, safeguards less and conveniently, needs supporting and guiding device few, and pipeline stress is eliminated thorough, the cost saving and the energy etc.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
A kind of spherical linkage comprises spheroid 1, ball seat flange 2, ball cover live flange 3, two pipeline adpting flanges 4, seal washer 8 and stuffing box packing 9.Spheroid 1, ball seat flange 2, two pipeline adpting flanges 4 are all selected the 15CrMO steel for use, and the ball cover flange 3 of living is selected the QAl9-2 aluminum bronze for use, makes through forging, heat treatment, surface finish and machining.Dead for preventing rust, guarantee to use the back to rotate flexibly, be coated with high temperature grease on the spheroid surface.The flanged surface of flange 3 is processed into the annular groove of sealing filler ring 8 but ball cover is lived, the flanged surface of corresponding ball seat flange 2 is processed into the annular boss that compresses seal washer 8, ball seat flange 2 and ball cover flange 3 alive all is processed into the concave spherical surface that matches with spheroid 1, wherein ball cover flange 3 alive and ball seat flange 2 are sleeved on the spherical portion of spheroid 1 respectively from the both sides end to end of spheroid 1, by screw rod 5, nut 6, spring washer 7 is fastening with ball seat flange 2 and ball cover flange 3 alive, ball seat flange 2 that tightens together and ball cover flange 3 alive is rotatably assorted with concave spherical surface and spheroid 1, and the maximum flex cone angle is 40 ° in relative rotation.Two pipeline adpting flanges 4 are solid weldings distolateral at spheroid 1 and ball seat flange 2 respectively, and be fixed as one with spheroid 1, ball seat flange 2, wadding warp is crossed the numb packing_seal filler 9 of mineral oil and plumbago processing in the ring-type pit of described ball cover flange 3 alive, seal washer 8 is pressed on ball cover and lives in the annular recess on the flange 3, constitute spheroid and rotate flexibly, the novel ball hinge that sealing, high-temperature high-pressure medium lubricated, that guarantee conveying do not leak.
