Abstract
The utility model discloses a swivel joint. Existing pipe joints adopting integrated coupling suffer leakage and even failure of connection during rotation. The product comprises a pipe (1). A group of recesses (2) are arranged on the lateral of one end of the coupling plane of the pipe (1); the end of the coupling plane bearing a group of recesses (2) mates with a reducing sleeve (3) in radial direction; recesses or grooves are also prepared at the location where the inner flank of the reducing sleeve (3) corresponds with the recesses (2) on the pipe (1); steel balls (4) are arranged in the recesses or grooves (3); and a steel-ball mounting hole (5) is prepared on the reducing sleeve (3). The product is used to seal the joint under rotating condition.
Description
Technical field: the utility model relates to a kind of SEALING FITTING that can use under rotation status.
Background technique: existing pipe joint adopts and is fixedly connected, and loses efficacy in case rotation will cause to leak even connect.
Summary of the invention: the purpose of this utility model is to provide a kind of swivel joint.
Its objective is such realization:
Swivel joint, its composition comprises: pipe, the one end outside of described pipe has one group of pit, a described end that has a pit and reduction center caliber are to cooperating, the sleeve pipe inboard is to having pit or groove, in described pit or the groove steel ball is housed, has the steel ball mount inlet on the described reducing sleeve pipe.
Above-mentioned swivel joint, the other end of the other end of described pipe and/or described reducing sleeve pipe have a screw thread.
Above-mentioned swivel joint has seal ring on the described radial fit face.
Its advantage is:
1. can adapt to rotation status and use, when sleeve pipe one sideway swivel, the steel ball supporting sleeve in the sleeve pipe rotates around pipe 1, and moving axially between limiter tube and the sleeve pipe, can allow mutual rotation between the pipe of these sample joint both sides.
2. can when liquid in pipe pressure is bigger, when adopting matching trim to be not enough to prevent to leak, the form that has seal ring can be adopted as the joint of high-pressure liquid line, the leakage of highly pressurised liquid can be effectively prevented.
3. scyewed joint can be adopted in the both sides of pipe joint, can adopt welding for pressure duct.
4. on the reducing sleeve pipe, have the steel ball mount inlet, can load and unload, overhaul steel ball.
Description of drawings: accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is left views of accompanying drawing 1.
Embodiment:
Embodiment 1:
Swivel joint, its composition comprises: pipe 1, the outside of conjunction plane one end of described pipe 1 has one group of pit 2, a described end and reducing sleeve pipe 3 radial fit that have the conjunction plane of pit 2, the inboard of sleeve pipe 3 and pipe 1 pit 2 corresponding positions also have pit or groove, in described pit or the groove 3 steel ball 4 is housed, has steel ball mount inlet 5 on the described reducing sleeve pipe 3, described steel ball mount inlet 5 cross sections are greater than circle of steel ball size etc., above on be stamped or sealing cover 6 arranged by scyewed joint, described reducing sleeve pipe 3 one ends are enclosed within on the pipe 1, and the other end can become same footpath or the Different Diameter pipe with pipe 1 outer connecting end.
Embodiment 2:
Above-mentioned swivel joint, described pipe 1 away from the other end of conjunction plane and/or described reducing sleeve pipe 3 away from the other end of conjunction plane have a screw thread 7, externally scyewed joint is adopted in connecting tube.
Embodiment 3:
