Abstract
The utility model relates to a self sealed pipe joint. A seal matching surface and through holes are arranged at a contact site of a left body with a right body, each through hole is provided with a ball sealer inside, the diameter of the ball sealer is bigger than the diameter of a corresponding hole at a sealed site of the through hole, a compression spring which is fixed on a hollow fixed support is arranged behind the ball sealer, and fastening braking elements for the left body and the right body are also arranged behind the ball sealer. The utility model has the advantages of quick and convenient mounting and dismounting, no oil leakage, safe use and high bearing capability. The utility model can be widely used for various liquid pipelines, especially suitable for high-pressure oil tubes between oil wells and blowout preventers in petroleum industry.
Description
The utility model relates to the interconnection technique field of tube and tube.
Present various hydraulic equipment generally adopts dog leg head straight-through type joint, and in the device maintenance disassembly process, a large amount of leaked liquids cause significant wastage, and severe contamination environment, the dog leg head be because of can not freely adjusting direction, puts that dismounting causes difficulty to equipment.
The purpose of this utility model provides a kind of nonspill coupling, and it has easy accessibility, oil-proof, safe and reliable, characteristics that bearing capacity is high.
Technological points of the present utility model is: a kind of nonspill coupling, it is characterized in that having left body and right body, be provided with through hole in left side body and the right body, left side body and right body contacting point have the face of being sealed and matched, and be provided with ball sealer, the diameter of ball sealer is greater than the diameter of through hole sealing part corresponding aperture, and the ball sealer back is equipped with the pressure spring (comprising elastic rubber fitting) that is fixed on the hollow fixed support, and is provided with the fastening clutch piece of left body and right body.
The above-mentioned face of being sealed and matched can be plane, sphere or the conical surface etc., and fitting surface can directly seal, or adds the seal ring sealing.
Above-mentioned fastening piece can be nut, and this nut inner hole is provided with that back-up ring and back-up ring be rotatably assorted is rotation boss on the right body, and left external side is provided with screw thread.Be easy disassembly, nut can adopt the three-jaw attaching nut.
Above-mentioned nonspill coupling dismounting is convenient, the recipient is not to influence in order to make, use reliable, safety, left body or right body are linked to each other with a universal pipe joint by bend pipe (90 ° or 60 °), this universal pipe joint structure is: the core pipe inserts in the sleeve pipe, core pipe excircle is provided with groove, and internal surface of sleeve pipe is provided with corresponding groove, is provided with ball in two grooves, sleeve pipe side respective slot place has ball and puts into the hole, and core pipe end and sleeve pipe contact segment are provided with seal ring.
Groove on the above-mentioned core pipe can be 1, more than 2 or 2, and ball is put the available at ordinary times stopper of manhole beyond the Great Wall.
The utility model is owing to adopted the resilient balls self-packer and the sealing surface sealing, so it is oil-proof in the working procedure, safe in utilization, reliable, when dismounting, ball is self-styled, can leakage of oil yet, and cause waste and pollute, easy accessibility, especially add after the elbow universal pipe joint that use conveniently, dismounting is more quick.This structure bearing capacity height.Can be adapted at using in the various liquid lines of every profession and trade, industries such as metallurgy, chemical industry, machinery, building, medicine for example are particularly useful for using in the high-pressure oil pipe between oil well and preventer in the petroleum industry.
Further describe the utility model below in conjunction with embodiment, but not as to qualification of the present utility model.
Fig. 1 is embodiment 1 a structural representation.
Fig. 2 is embodiment 2 a structural representation.
Among Fig. 1, left side body 1 and right body 3 are respectively equipped with the face of being sealed and matched 10,9 and through hole 15,5, ball sealer 11,8 diameter is all located the diameter of through hole greater than being sealed and matched, ball sealer 11, there is spring 12 8 back, 7, spring 12,7 are enclosed within triangle skeleton 13, on 6,14,4 is the jump ring back-up ring, fastening clutch piece 3 is a three-jaw attaching nut, and nut end has the protruding circle on back-up ring and the right body 3 to be rotatably assorted, and left external side is established screw thread, when fastening clutch piece is fastening, body right body sealing surface in a left side overlaps, two ball sealer jam-packeds, and through hole is opened, when fastening piece unclamps, left body, right body is then from motive sealing.
Among Fig. 2, left body 1 and right body 3 are provided with sealing plane 16,19, and plane 16 is provided with seal ring 17, fastening piece 18 is six square nuts, and right body 3 is connected with bend pipe 20, and bend pipe 20 is connected with core pipe 21, on groove 22 is arranged, it is steel ball that sleeve pipe 23 endoporus have groove 24,25, puts the people from hole 26, available at ordinary times stopper 27 is blocked, whole pipe joint is turned to flexibly, and dismounting is very convenient, uses reliable.
