Installation steps and method, referring to Figure 10：
(1) other end of coupling 1 is connected with Hydraulic Elements is finished, and O-ring seal 23 is placed in nipple 1
In side 3.
(2) fixing ring 4 is placed on the inboard face 27 of coupling 1.
(3) special-shaped flexibly positioned sleeve 5 is filled in coupling 1, is made in left surface 25 and the coupling 1 of fixing ring 4
Side 27 is contacted, and the right flank 26 of fixing ring 4 is in close contact with a special-shaped elastic locating sleeve 5.
(4) the vulcanization sleeve 6 of the metal after vulcanizing treatment is filled in.Can be integrated after vulcanizing treatment the high resiliency of rubber with
The high intensity of metal.
(5) external skull 2 is screwed on the lateral surface screw thread 21 of coupling 1, such as Fig. 7 by screw thread 22.Make special-shaped elasticity fixed
Position sleeve 5 is in close contact with metal vulcanization sleeve 6, and the inboard face 28 of metal the vulcanization right flank of sleeve 6 and external skull 2 closely connects
Touch.So as to which the axial location of the flexibly positioned sleeve 5 of abnormity is fixed.O-shaped sealing is placed in the square groove 11 of external skull 2
Packing ring 30.
(6) nipple 7 is inserted in coupling 1, until the V-type convex body 15 of the flexibly positioned sleeve 5 of abnormity is caught in nipple 7
Groove 12 in, so as to avoid nipple 7 depart from coupling 1 rise.The axial location of nipple 7 is fixed.It is now outer
The O-ring seal 23 in the inboard face 3 of joint 1 is also compressed.
(7) inscribed skull 8 is screwed into the screw thread 10 of nipple 7 by screw thread 29.The quilt of O-ring seal 30 of external skull 2
Compression.Completion is assembled in nipple 7 and coupling 1 first.
The present invention use for laboratory connection Hydraulic Elements a kind of Fast Installation dismounting oil connection, its demounting procedure and
Method is：
(1) inscribed skull 8 is continued to twist to the left by screw thread 29, abnormity can be jacked up when continuing rotation to inscribed skull 8
During the V-type convex body 15 of flexibly positioned sleeve 5, now, the V-type convex body 15 of the flexibly positioned sleeve 5 of abnormity also no longer connects with nipple 7
