Abstract
The utility model relates to a rotating joint. The existing pipe joints can not rotate due to the adoption of fixed connection, once the pipe joints are rotated to result in pipe leakage at the joint positions and even connection failures, the purpose of pipeline connection can not be achieved. The rotating joint of the utility model comprises a connecting pipe 1, wherein a set of convex pits or grooves 2 are arranged on the outer wall of the connecting pipe 1, one end of the connecting pipe 1, which is provided with the convex pits or the grooves 2, is radially matched with a diameter changing sleeve pipe 3, inner holes of the diameter changing sleeve pipe 3 correspond to the convex pits or grooves 2 along the radial direction, steel balls 4 are arranged in the convex pits or grooves 2, and the diameter changing sleeve pipe 3 is provided with steel ball mounting and dismounting holes 5 along the radial direction. The utility model can be used as a sealing joint used in the rotating state.
Description
Technical field: the utility model relates to a kind of swivel joint.
Background technique: existing pipe joint all adopts fixedly connected, can not rotate, and causes the leakage of pipe even connects inefficacy in case be rotated in joint area, thereby can not reach the purpose of connecting pipeline.
Summary of the invention: the purpose of this utility model provides a kind of rotatable joint.
Above-mentioned purpose realizes by following technological scheme:
Swivel joint, its composition comprises: connecting tube, have one group of pit or groove on the outer wall of described connecting tube, the end that described connecting tube has pit or a groove and reduction center caliber are to cooperating, the endoporus of described reducing sleeve pipe is radially to having pit or groove, in described pit or the groove steel ball is housed, described reducing sleeve pipe radially has steel ball installation, removal hole.
Above-mentioned swivel joint, the other end endoporus of the other end of described connecting tube and/or described reducing sleeve pipe has screw thread.
Above-mentioned swivel joint has O-ring seal on the radial fit face of described connecting tube and described reducing sleeve pipe.
This technological scheme has following beneficial effect:
1. swivel joint of the present utility model, owing on the end face that connecting tube and reducing sleeve pipe combine, steel ball is housed, its steel ball supports the reducing sleeve pipe and rotates around connecting tube, and can limit moving axially between connecting tube and the reducing sleeve pipe, thereby this structure can adapt under the rotation status and to use, and can allow mutual rotation between two pipes.
2. this product can be used as the joint of high-pressure liquid line, when liquid in pipe pressure is big, when adopting matching trim to be not enough to prevent to leak, adopts the O-ring seal sealing, can effectively prevent the leakage of highly pressurised liquid.
3. the two ends of connecting tube of this product and reducing sleeve pipe have the connection screw thread, to using under the general pressure condition, when big as if fluid pressure, can adopt welding manner to be fixedly connected to the pipeline two ends.
4. the reducing sleeve pipe of this product has radially that steel ball is installed, removal hole, but convenient assembling and disassembling, maintenance steel ball.
5. this product has simple in structurely, uses characteristics such as reliable, easy for installation.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is left views of accompanying drawing 1.
Embodiment:
Embodiment 1:
Swivel joint, its composition comprises: connecting tube 1, have one group of pit or groove 2 on the outer wall of described connecting tube 1, described connecting tube 1 has an end and reducing sleeve pipe 3 radial fit of pit or groove 2, the endoporus of described reducing sleeve pipe 3 radially also has pit or groove with the groove or pit 2 corresponding positions of described connecting tube, steel ball 4 is housed in described pit or the groove, and described reducing sleeve pipe 3 radially has steel ball installation, removal hole 5.
Embodiment 2:
Above-mentioned swivel joint, the other end endoporus of the other end of described connecting tube 1 and/or described reducing sleeve pipe 3 has screw thread 7, and externally scyewed joint is adopted in connecting tube.
Embodiment 3:
Above-mentioned swivel joint has O-ring seal 8 on the radial fit face of described connecting tube 1 and described reducing sleeve pipe 3.
