The utility model adopts technique scheme, and two sections interior pipes that connect and outer tube all are designed to have certain camber, by the seat that is rotatably connected interior pipe and outer tube are closely coupled together, and also easy to loading and unloading, simple in structure, be easy to safeguard.
Description of drawings
Fig. 1 is the utility model whirl compensator structural representation;
Fig. 2 is Fig. 1 exploded view.
Embodiment
The utility model provides a kind of follow-on whirl compensator, and is clearer, clear and definite for making the purpose of this utility model, technological scheme and advantage, below with reference to the accompanying drawing embodiment that develops simultaneously the utility model further described.
In that being installed, whirl compensator need add the inconvenience that bend pipe brings and the problem of demolition and maintenance difficulty in order to solve prior art, innovative point of the present utility model is: the body that two sections interior pipes that link together and outer tube all are designed to have certain camber, and by one be rotatably connected the seat interior pipe and outer tube are closely coupled together, dismounting and maintenance are convenient, in the time whirl compensator need being installed in the turning of pipeline, need not increase extra bend pipe, easy to use.
In conjunction with illustrated in figures 1 and 2, the utility model comprises: interior pipe 10, outer tube 20, sealing gland 30, sealing seat 40, the spacing collar 50 and the seat 60 that is rotatably connected, wherein, adopt sealing gland 30, sealing seat 40, the spacing collar 50 and the seat 60 that is rotatably connected are connected with group interior pipe 10 and outer tube 20, outer tube is a special-shaped curve bend (a reducing bend pipe), one end of interior pipe 10 inserts in the outer tube 20, interior pipe 10 is inserted into outer tube 20 1 ends and is big end, its diameter is greater than the diameter (end diameter of outer tube 20 the other ends, end diameter is identical with the diameter of interior pipe 10), interior pipe 10 comprises straight tube and bend pipe, and the diameter of straight tube and bend pipe is identical; The straight-tube portion of interior pipe 10 stretches to its inside from outer tube 20 Outside diameters; Be welded on the periphery wall of pipe 10 and with it in the spacing collar 50 is linked in and form an annular boss on the periphery wall, the junction of pipe 10 and outer tube 20 in this boss places, be rotatably connected the seat 60 inside be stepped cylinder, be provided with some bearings at the annular boss lower surface be rotatably connected seat 60 binding site places and annular boss upper surface and sealing seat 40 binding site places, bearing is separately positioned on the groove interior (groove of being opened is not shown) of annular boss upper surface and lower surface, by seat 60 location that are rotatably connected, seat 60 and sealing seat 40 are pushed down bearing together by being rotatably connected, pass through bolt then, the flexibility of rotating when bearing is used to guarantee to compensate; Pipe 10 straight tube places and placing on the spacing collar 50 in sealing gland 30, sealing seat 40 be linked in, the upper end outer perimeter wall of outer tube 20 and 60 the lower end inwall of being rotatably connected are by being welded to connect.
