Installation steps and method, referring to Figure 10:
(1) 1 other end of coupling is connect with Hydraulic Elements finishes, and O-ring seal 23 is placed on to the inside of nipple 1
In face 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 side 25 and the coupling 1 of fixing ring 4
Side 27 contacts, and the right side 26 of fixing ring 4 and a special-shaped elastic locating sleeve 5 are in close contact.
(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 1 lateral surface screw thread 21 of coupling, by screw thread 22 such as Fig. 7.Keep special-shaped elasticity fixed
Position sleeve 5 and metal vulcanization sleeve 6 are in close contact, and metal vulcanization 6 right side of sleeve and the inboard face 28 of external skull 2 closely connect
Touching.To which the axial position of the flexibly positioned sleeve 5 of abnormity is fixed.It placed O-shaped gasket in the square slot 11 of external skull 2
Circle 30.
(6) nipple 7 is inserted into coupling 1, until the elastic component 15 of the flexibly positioned sleeve 5 of abnormity is caught in nipple 7
Lock groove 12 in, so as to avoid nipple 7 be detached from coupling 1.The axial position of nipple 7 is fixed.It is outer at this time
The O-ring seal 23 in the inboard face 3 of connector 1 is also compressed.
(7) inscribed skull 8 is screwed into the screw thread 10 of nipple 7 by screw thread 29.30 quilt of O-ring seal of external skull 2
Compression.Completion is assembled in nipple 7 and coupling 1 for the first time.
A kind of oil connection of Fast Installation disassembly of use for laboratory connection Hydraulic Elements of the invention, demounting procedure and
Method are as follows:
(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
When the elastic component 15 of flexibly positioned sleeve 5, at this point, the elastic component 15 of the flexibly positioned sleeve 5 of abnormity also no longer connects with nipple 7
Touching, the axially position of nipple 7 are destroyed, and the screw thread 29 and screw thread 10 between inscribed skull 8 and nipple 7 are interior also without interference
Connector 7 can be extracted easily from coupling.
When needing nipple 7 accessing coupling 1 again, it is only necessary to operate two steps.
