Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is further described.The most identical parts phase
Same reference represents.It should be noted that the word "front", "rear" used in describing below, "left", "right", " on " and
D score refers to the direction in accompanying drawing, and word " bottom surface " and " end face ", " interior " and " outward " refer respectively to towards or away from specific
The direction at component geometry center.
With reference to shown in Fig. 1, a kind of flange pipe, including the body 1 being made of metal and flange 2, the outer one of flange 2 enclose to
Body 1 side is bent with elastic deformation ring 21, and flange 4 bear against elastic deformation ring 21, and such flange 2 axially clamps work bearing
The elastic deformation of lift-off seal can be produced time firmly.This is also that its intensity of flange 2 that metal is made is enough, at flange 4 relatively
Also it is only capable of under strong axial compressive force producing slight deformation, just makes the bottom surface of flange 2 conflict with composition surface and fit, thus improve contact
The sealing in face.
With reference to shown in Fig. 1, flange 2, substantially in horn-like, makes flange 2 arrange with the inclined structure of outer wall of body 1, flange
2 angles formed with the outer wall of body 1 are obtuse angle, and flange 2 so can be made further to produce when flange 4 tabletting is on flange 2
Raw elastic deformation, thus strengthen the seal degree of flange 2 and composition surface, be conducive to improving sealing effectiveness.Flange 2 and body 1
When the angle of outer wall is between 93 °-95 °, flange 2 elastic deformation when bearing axial compressive force can be made, also can cancel this
Recover itself shape of flange 2 during axial compressive force, elastic packing state can not only be kept for a long time, more can be in dismounting maintenance
After also there is elastic packing.This flanging 2 is the biggest with the angle of body 1 outer wall, and metal is easily generated fatigue thus reduces use
