It is connected to gasket made of rubber.
By using above-mentioned technical proposal, the gap filling between rear end cap and shell is lived using the elasticity of gasket,
Gap location outflow of the gas between rear end cap and shell is avoided, the leakproofness of rotary joint is further increased.
The utility model has the following beneficial effects:
1, the utility model is avoided high steam from being directly entered hollow shaft and is made to equipment by setting lower inlet and lower flow channel
At damage；
2, by setting spring, pushing block and sealing block, steam is avoided to flow out between shell and hollow shaft, improves rotation and connects
The leakproofness of head；
3, it by setting gasket, avoids steam from flowing out between shell and rear end cap, further increases rotary joint
Leakproofness.
