The present invention compared with prior art, has following good effect:
1. metal elastic-sealed ring is set at the outer convex shoulder cylindrical position of core pipe, metal elastic-sealed ring opening offset is arranged, metal elastic-sealed ring has good seal action to high temperature, high-pressure medium, sleeve expansion joint is made to have well high temperature resistant, high-voltage performance, medium engineering pressure≤6.3MPa, medium temperature-40 DEG C ~ 700 DEG C.
2. the metal elastic-sealed ring opening offset of twice 90 ° of layouts, can ensure sealing effect further.
3. twice y-shaped ring is set at core pipe outer convex shoulder cylindrical position, forms combined seal structure with metal elastic-sealed ring, improve sealability further; Y-shaped ring opening is towards adapter, when there being medium to rush at seal ring, pressure medium makes y-shaped ring opening open, pressure medium is higher, y-shaped ring opening Zhang get Yue opens, and namely pressure medium is higher, and sealing effect is better, significantly improve sealing effect, also significantly increase the high-voltage resistance capability of sleeve expansion joint.
4. in the outer convex shoulder annular groove outside of core pipe, guide ring is set, effectively improves during compensator uses the stationarity operated, prevent eccentric wear, increase the service life.
5. outer sleeve inner wall is provided with wearing layer, can working life of significant prolongation compensator.
6, core pipe and nozzle inner wall are provided with anti-corrosion layer, significantly improve the corrosion resistance of compensator, extend the working life of compensator.
7. outer sleeve, take over and form by straight tube and flange welding, without the need to adopting large-sized blank to process, significantly reduce manufacture cost.
