Detailed description of the invention
The present invention is made up of standing part and removable section two large divisions, and wherein standing part is installed on vacuum tank, Flange joint, and 0 type circle seals.Casing outer with fill helium recovery system and be connected, casing is interior to be connected with workpiece.
Wherein, mounting flange group 1, counter flange group 2 are respectively weld assembly, postwelding electrochemical polishing, it is ensured that inner surface is smooth, reduce helium Molecular Adsorption.
Standing part assembling process: first by threaded for the female 3 of mounting flange group 1 and quick connector and fasten, again O 5 is loaded in counter flange group 2 seal groove, finally mounting flange group 1 is loaded together with counter flange group 2 in flange hole reserved in vacuum chamber (see figure 1), and fasten with screw.Spacer shell 4 and clip 6 are installed after detachable part is distributed into.
Removable section assembling process: first connector cap 13 is inserted in connector 12, successively by connector 12, pipe coupling 14, double nipple 16, quick connector female 7 between carry out taper thread connection and fasten, again connector 12 is threadeded with bite type nipple 15, subsequently high-pressure nylon pipe 20(is taken appropriate length) insert bite type nipple 15, the nut of tightening card shell type nipple, makes high-pressure nylon pipe 20 and bite type nipple 15 compact siro spinning technology.
Take the transparent steel wire vacuum pipe 21 of appropriate length, outer layer pipe cap 19 is inserted at two ends, transparent steel wire vacuum pipe 21 is inserted respectively flexible pipe bearing 11 and connection dish 22 small end, outer layer pipe cap 19 is screwed in respectively flexible pipe bearing 11 and connection dish 22 screw thread again, flexible pipe bearing 11 right side seal groove loads O 18, connector cap 13, from the outer tube that right-hand member plugging in fitting is good transparent steel wire vacuum pipe 21, is threaded into flexible pipe bearing 11 right-hand member screw thread and fastens by the inner tube high-pressure nylon pipe 20 that fetching prepares.
Finally high-pressure nylon pipe 20 left end is inserted bite type nipple 15, and fasten clamp nut, make high-pressure nylon pipe 20 and bite type nipple 15 compact siro spinning technology, the male 23(coring of bite type nipple 15 end of thread and quick connector) threaded and fasten.
When carrying out helium leak check with vacuum tank equipment, directly by removable section left end quick connector male 23(coring, Fig. 3) insert standing part quick connector female 3(Fig. 2), outer layer clip 6(Fig. 2) by spacer shell 4(Fig. 2) be connected dish 22(Fig. 3) quickly connect.Female 7(Fig. 3 of right-hand member quick connector) direct connection with examined workpiece can carry out vacuum tank helium leak check.
When leakage occurs in vacuum tank leak detection system, and impact is continuing with, in order to get rid of the leakage problem of vacuum tank own, case inner flexible tube removable section quickly can be removed, carry out leak detection is installed by Fig. 4.
The most quickly remove clip 6, take off case inner flexible tube removable section, then will insert plug 32 soon and insert the female 3 of quick connector, and finally with clip 6, spacer shell 4 will quickly be connected with standing part and closure plate 34.
