Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, it can be seen that: the utility model provides a rotation type compensator that sealing performance is good, includes core pipe 1 and outer tube 6, the body of core pipe 1 forms convex body 2 around the axial direction evagination, the fixed pipe 3 of installation is established to the outside cover of convex body 2, convex body 2 is the hump structure, the inboard of fixed pipe 3 is sunken along the inboard of convex body 2, circular ring groove 4 is seted up at the inboard middle part of fixed pipe 3, installation activity ring 5 between circular ring groove 4 and the convex body 2, the tip installation outer tube 6 of core pipe 1, the tip of core pipe 1 is turned over and is formed edge 7, the first crown plate 8 of right side welding of outer tube 6, the left side welding second crown plate 9 of first crown plate 8, the sealed laminating of second crown plate 9 is at the surface of fixed pipe 3, fill sealing material 10 in the clearance space between core pipe 1, outer tube 6, first crown plate 8, second crown plate 9 and the fixed pipe 3, third crown plate 11 is established to the left side cover that core pipe 1 is located fixed pipe 3, second crown plate 8 runs through around the center of the ring and sets up perforation 12, perforation 12 department installation screw 13, the tip welding of screw 13 is on third crown plate 11, the installation limiting plate 14 is established to the cover on the screw 13 in the first crown plate 8 outside, the coaxial welding nut 15 in the outside of limiting plate 14, nut 15 connects soon with screw 13 screw thread, spring 16 is established to the cover on the screw 13 between limiting plate 14 and the first crown plate 8.
