Specific implementation mode
Specific embodiment of the utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 illustrates a kind of rotatable pipeline sealing structure, includes the sealed end 3 of cooperation left pipe 4 and 1 connector of right pipe,
Further include the round end 2 of right pipe 1 of being connected by slewing equipment 5, the slewing equipment 5 is bearing；The sealed end and rotation
The general outline shape for turning end can be the composite figure of disk and cylinder, and the sealed end 3 and round end 2 are equipped with terminal pad
9, the terminal pad 9 can be ring flange, and the sealed end 3 and round end 2 are bolted by terminal pad 9, and the sealed end 3 is also
Equipped with joint cavity 8, at least two lip packing slots 6 are equipped in the joint cavity 8, sealed end 3 passes through the sealing ring in seal groove 6
61, which are respectively cooperating with left pipe 4 and right pipe 1, is tightly connected, and is seal chamber 81 between the lip packing slot 6, and left pipe 4 and right pipe 1 connect
Head is located in seal chamber 81, and the sealing ring 61 can be lip-type packing, in the end face that the sealed end 3 is connect with round end 2
Gasket 7 is equipped at circle, the width of the gasket 7 is more than the thickness of bearing, this is the second leak-proof measure, one side leakproof,
On the other hand liquid is made not flow in bearing.Bearing inner race is fixedly connected with right pipe 1, and outer ring fastens close fit with round end,
Round end 2 is connect with 3 end flanges of sealing, and sealed end 3 can be connected through a screw thread with left pipe 4.In this way, pipeline can be made in sealing state
