Contact.
As a further improvement of the utility model, the one end of the external compacting ring be provided with one it is same with terminal pad
The fixed ring of equal outer diameters, fixed ring are contacted with terminal pad.
It is linear structure that the both ends of the tube shell, which are each provided with one section of axis, as a further improvement of the utility model,
Linkage section, be attached between the side wall of the external compacting ring and the linkage section inner wall of tube shell by screw thread.
The beneficial effects of the utility model are:
1, the utility model realizes installation of the liner in elbow by one group of dismountable stainless steel inner lining structure, removable
It unloads structure to be conveniently adjusted, and can be put into before elbow installation, can flexibly select the stainless of different size as needed
Furthermore steel has benefited from dismountable inner lining structure, outer tube can be integrally manufactured, is not restricted by inner tube, improves intensity, reduces
Cost.
2, the approaching face of concave inward structure has bigger contact area, and protruding ring may be implemented to connect with the close of approaching face
Touching, to guarantee sealing effect.
3, the contact of the stainless steel material between connector and connector or pipeline may be implemented in fixed ring, guarantees the close of liner
Seal effect.
4, the linkage section of linear structure is convenient for the fixation of external compacting ring, and threaded connection also improves stability, in elbow
The fixation of external compacting ring can be realized before connection, and does not depend on the connection of clip, so that installation is more convenient.
