Abstract
The invention relates to a universal flex device of oil sealing tube, which comprises a core tube, two fixing frame and a sealing device. Wherein, said core tube is formed by spherical tube and cylinder tube; the spherical tube, its fixing frame and compression flange form the spherical rotation couple, to form one seal chamber; said seal chamber is arranged with sealing ring and oil seal stuff, while the middle of outer wall is arranged with oil hole and sealing bolt; the cylinder tube, its fixing frame and compression flange form straight motion couple and form one seal chamber; said seal chamber is arranged with sealing ring and oil seal stuff, while the middle of outer wall is arranged with oil hole and sealing bolt; the sealing ring is made from asbestos coil root or politef; the seal stuff is flexible graphite. The invention can realize universal angle compensation and axial compensation, to confirm the normal application of tube; and it uses injection oil seal stuff to seal, with better effect; and it can compensate the extension and non-uniform deposition of tube in long-distance lay, caused by temperature.
Description
One. technical field: the present invention relates to a kind of pipeline compensator, particularly relate to a kind of universal expansion joint for oil seal pipeline.
Two. background technique: pipeline compensator is an imperative equipment during national pipe network is laid; present domestic main employing bushing type expansion bend; according to the concrete structure difference; the bushing type expansion bend that has is merely able to realize axial rising-heat contracting-cold compensation; the spherical compensator that has is merely able to realize angle compensation; but; their ubiquitous defectives are: reveal easily; the Maintenance and Repair workload is big; when amount of leakage needs repairing greatly, need to shut down, stop work so very big terminal use that influences; and long in time limit, the maintenance cost height.
Three. summary of the invention:
Purpose of the present invention: overcome the defective of prior art, a kind of good sealing effect is provided, is easy to installation and maintenance, integrates the universal expansion joint for oil seal pipeline of angle compensation and nose balance.
Technological scheme of the present invention: a kind of universal expansion joint for oil seal pipeline, contain a core pipe and two stationary housings, and the two ends of core pipe are set in two stationary housings, be provided with seal arrangement between core pipe and the stationary housing, described core pipe partly is made up of spheroid tubular portion and cylindrical tube, and the outer spherical surface two ends of spheroid tubular portion respectively with this end stationary housing inwall on and on the supported flange inwall sphere that is provided be complementary, this end supported flange is connected with this end stationary housing by bolt, the spheroid tubular portion is fixed, and the spheroid tubular portion can freely be turned an angle, realize universal compensation, this end supported flange, the outer spherical surface middle part of stationary housing inwall and spheroid tubular portion forms a closed cavity, the two ends of cavity are respectively arranged with a seal ring, enough stuffing box packing are injected at the middle part of cavity, and its outer wall is provided with the oil hole and the sealing bolt of some; The external diameter of described cylindrical tube part and the bulge loop internal diameter on this end stationary housing inwall are complementary, to realize nose balance, and should be connected with this end supported flange by bolt by the end stationary housing, the outer surface of this end stationary housing and bulge loop, this end supported flange, cylindrical tube part forms a closed cavity, the two ends of cavity are respectively arranged with a seal ring, enough stuffing box packing are injected at the middle part of cavity, and its outer wall is provided with the oil hole and the sealing bolt of some.
Described oil hole circumferentially, and on the set casing body wall between the adjacent hold-down bolt on the stationary housing flange.
Described seal ring is asbestos packing or teflon, and described stuffing box packing is an Expanded graphite, and described rotation angle α is 10 °～15 °.
Beneficial effect of the present invention:
1. core pipe of the present invention partly is made up of spheroid tubular portion and cylindrical tube, and the spheroid tubular portion forms sphere with this end stationary housing and supported flange and contacts, can realize universal angle compensation, the cylindrical tube part contacts with this end stationary housing and supported flange formation straight line in addition, can realize nose balance, eliminated because of installation, surface subsidence or the angle and the axial error that expand with heat and contract with cold and cause, guaranteed the normal use of pipeline.
2. sealing effect of the present invention is good, adopts the oil-filling type sealing between core pipe and the stationary housing, promptly injects enough oil seal fillers in the cavity between sealed at both ends ring, has improved lubricity, has strengthened withstand voltage degree, increases sealing effect greatly.
3. core pipe of the present invention is connected with stationary housing with bolt by supported flange, so installation and maintenance are convenient, reduce construction cost; be in operation in addition; in case occur revealing, need not shut down, can unclamp sealing bolt; directly in Seal cage, inject enough stuffing box packing; tighten sealing bolt again and get final product, thereby realize and on non-stop-machine basis, to keep in repair, save time, laborsaving, economical; convenient and swift, increase work efficiency greatly.
4. the present invention is widely used in heating power, boats and ships, oil, gas, water supply and sewerage pipeline, compact structure, and mounting or dismounting are convenient, are easy to promote, and have good social and economic benefit.
5. the present invention integrates angle compensation and nose balance, and volume is little, in light weight, compensation rate is big, applied widely.
Four. description of drawings:
Fig. 1 is the structural representation of universal expansion joint for oil seal pipeline
Five. embodiment:
Embodiment: referring to Fig. 1, among the figure, the core pipe 6 of universal expansion joint for oil seal pipeline partly is made up of spheroid tubular portion and cylindrical tube, and the outer spherical surface two ends of spheroid tubular portion respectively with this end stationary housing 1 inwall on and on supported flange 5 inwalls sphere that is provided be complementary, this end supported flange 5 is connected with this end stationary housing 1 by bolt, the spheroid tubular portion is fixed, and the spheroid tubular portion can freely be turned an angle, realize universal compensation, its rotation angle α is 10 °～15 °, this end supported flange 5, the outer spherical surface middle part of stationary housing 1 inwall and spheroid tubular portion forms a closed cavity, the two ends of cavity are respectively arranged with a seal ring 2, enough stuffing box packing 3 are injected with portable injection molding machine in the middle part of cavity, and its outer wall is provided with the oil hole and the sealing bolt 4 of some; The external diameter of cylindrical tube part and the bulge loop internal diameter on this end stationary housing 8 inwalls are complementary, and should be connected with this end supported flange 7 by bolt by end stationary housing 8, the outer surface of this end stationary housing 8 and bulge loop, this end supported flange 7, cylindrical tube part forms a closed cavity, the two ends of cavity are respectively arranged with a seal ring 11, enough stuffing box packing 10 are injected with portable injection molding machine in the middle part of cavity, and its outer wall is provided with the oil hole and the sealing bolt 9 of some.
