Symmetrically, draw ring circle 51 is set in joint lower part 31.Joint 3 and (the outer spiral shell of joint of gland 2 can be relatively rotated before use
Line 311 is threadedly coupled with gland internal thread 21), abutted at the top of draw ring circle 51 with the bottom of hoop portion evagination 322, the bottom of draw ring circle 51
Untill portion abuts with the top of gland 2 (draw ring circle 51 covers outer washer 316), when needing to use the present invention, then pass through handle 52
Draw ring circle 51 is taken off from joint lower part 31, then relatively rotates joint 3 and gland 2, until the top of gland 2 and outer pad
Untill circle 316 abuts, you can use the present invention.The effect of draw ring 5 is to make to stay between gland 2 and the joint lower part 31 of joint 3
There is space, now snap ring 4 is in relaxed state.Draw ring 5 is decontroled, while tightens joint 3 and gland 2, then snap ring 4 is just tightly
Hold bellows 1 tightly, while joint external screw thread 311 is tightened with gland internal thread 21, squeezing to inner washer 315 will be produced
Pressure, the present invention is set to reach good sealing effectiveness.
Inner washer 315 is 80 degree of hydrogenated butyronitrile glue (HNBR-80), and outer washer 316 and gland packing ring 24 are common NBR.
Gland 2 and joint 3 using copper content 59% 59-1 types ledrite (HPB59-1) or stainless steel, snap ring 4 use copper content for
62% brass (H62 copper).Snap ring 4 will not produce season cracking gas leakage using H62 copper compared to using for plastics.Round platform is empty
The tilt angle alpha of the round platform side wall 3131 of chamber 313 is 63 °, and round platform side wall 3131 is just tangent with snap ring arc 43.
The pulling force that the present invention can be born reaches 2.292KN.
The present invention use process be：
The side of snap ring arc 43 of snap ring 4 is stretched into the inner chamber of joint lower part 31, snap ring arc 43 and round platform side wall 3131
Contact, then draw ring 5 is set on the outer surface of outer washer 316, then the joint lower part 31 of joint 3 is passed through joint external screw thread
311 and gland internal thread 21 be transferred in gland 2, until the bottom of draw ring circle 51 of draw ring 5 and the top of gland 2 abut, and draw ring circle
(now joint external screw thread 311 and gland internal thread 21 do not turn completely untill 51 tops abut with the bottom of hoop portion evagination 322
Tightly, snap ring 4 is active state and is in the inner chamber of gland 2 and joint lower part 31, convenient installation), this is pre-installation；
A bellows 1 is chosen, the pipe skin of the end of bellows 1 is removed, the mouth of pipe of bellows 1 is stretched into pressure from the bottom of gland 2
Cover in 2 inner chambers, the mouth of pipe of bellows 1 passes through snap ring 4, and (mouth of pipe of bellows 1 is stretched into snap ring 4, and outside power is produced to snap ring arc 43
Deform snap ring arc 43, untill a crest of the top of bellows 1 stretches out snap ring arc 43), snap ring 4 passes through snap ring arc
43 are fixed on bellows 1 (snap ring arc 43 is caught in a trough of the top of bellows 1)；
Then draw ring 5 is removed by handle 52, continues the joint lower part 31 of joint 3 passing through the He of joint external screw thread 311
Gland internal thread 21 is transferred to gland 2, untill the top of gland 2 abuts with outer washer 316, snap ring arc 43 and round platform side wall 3131
Abut, abutted at the top of the mouth of pipe of bellows 1 with to slope 323, the mouth of pipe side wall of bellows 1 abuts with inner washer 315, installs
Into other pipelines etc. can be connected in joint upper part 33.
Conventional joint is all to want each structure to be directly installed on bellows 1, not easy to operate in small space, and this hair
It is bright to pre-install, then it is directly sleeved on bellows 1, simple installation, is operated suitable for small space.
The testing result of HNBR-80 and common butadiene acrylonitrile rubber by using GB/T 23658-2009 is respectively adopted in inner washer 315
As shown in table 1：
Table 1
Inner washer 315 is different using HNBR-80 and common butadiene acrylonitrile rubber material, and index is also slightly different, and is both adopted
With GB/T 23658-2009 standard.From table 1, in general inner washer 315 uses common butadiene acrylonitrile rubber intensity using HNBR-80 ratios
It is higher and be unlikely to deform and leak, it is more applicable for the present invention.Outer washer 316 and gland packing ring 24 seldom use thus using
Common NBR.
Contrast test 1：The quantity of snap ring 4 in embodiment 1 is increased or decreased, remaining is equal to embodiment 1；
First, 42 numbers of clasp piece of the snap ring 4 in embodiment 1 are changed to 16, remaining is equal to embodiment 1；
After the quantity increase of clasp piece 42 so that the intensity of snap ring 4 declines, and such snap ring 4 abuts with round platform side wall 3131
Power can reduce, bellows 1 easily damages the mouth of pipe of bellows 1 and interior to the power increase to slope 323 and the abutting of inner washer 315
Packing ring 315, the pulling force that whole device can be born are the 2.013KN (detections for the pulling force that the device in all contrast tests can be born
Method is identical with the present invention).
2nd, 42 numbers of clasp piece of the snap ring 4 in embodiment 1 are changed to eight, remaining is equal to embodiment 1；
After the quantity of clasp piece 42 reduces so that the flexibility decrease of snap ring 4, such snap ring 4 abut with round platform side wall 3131
Power can increase, cause bellows 1 be not easy with the abutting to slope 323 and inner washer 315, easily leak, whole device energy
The pulling force born is 2.121KN.
Contrast test 2：By the angle [alpha] increase of the round platform side wall 3131 of the round platform cavity 313 in embodiment 1 or reduce,
Remaining is equal to embodiment 1；
First, the angle [alpha] of the round platform side wall 3131 in embodiment 1 is increased to such as 70 °, remaining is equal to embodiment 1；
The direction for the power that round platform side wall 3131 abuts with snap ring 4 can convergence horizontal direction, such round platform side wall 3131 and card
Ring 4 reduces in the power of vertical direction, and bellows 1 easily damages bellows 1 to the power increase to slope 323 and the abutting of inner washer 315
The mouth of pipe and inner washer 315, the pulling force that whole device can be born is 1.975KN.
2nd, the angle [alpha] of the round platform side wall 3131 in embodiment 1 is decreased to 50 °, remaining is equal to embodiment 1；
The direction of the power that round platform side wall 3131 abuts with snap ring 4 can convergence vertical direction, snap ring 4 it is elastic insufficient when,
It can cause bellows 1 can not be with the abutting to slope 323 and inner washer 315, the production requirement to snap ring 4 improves, whole device energy
The pulling force born is 2.032KN.
Contrast test 3：By the increase of the angle beta to slope 323 in embodiment 1 or reduce, remaining is equal to embodiment 1；
First, the angle beta to slope 323 in embodiment 1 is increased to 30 °, remaining is equal to embodiment 1；
To the convergence of slope 323 with horizontal, vertical direction is leveled off to power caused by bellows 1 to slope 323, compared to original
Obliquely, sealing effectiveness is poor, easily leaks, and the pulling force that whole device can be born is 1.857KN.
2nd, the angle beta to slope 323 in embodiment 1 is decreased to 20 °, remaining is equal to embodiment 1；
When being extruded to the side of joint 3, the mouth of pipe of bellows 1 easily deforms the mouth of pipe of bellows 1, and the mouth of pipe diminishes so that
Gas output reduces, and produces failure.
Contrast test 4：Snap ring 4 in embodiment 1 is changed to the 59-1 types ledrite (HPB59-1) using copper content 59%
Or plastics.
When snap ring 4 is changed to the 59-1 type ledrites using copper content 59%, the elasticity of snap ring 4 reduces, and holds in use
Easy fracture, and snap ring 4 is not easy set and is set on bellows 1, the pulling force that whole device can be born is 2.104KN.Snap ring 4 uses plastics
When, in use can season cracking produce gas leakage, the pulling force that whole device can be born is 1.993KN.
Finally, it is also necessary to it is noted that listed above is only several specific embodiments of the invention.Obviously, this hair
It is bright to be not limited to above example, there can also be many deformations.One of ordinary skill in the art can be from present disclosure
All deformations for directly exporting or associating, are considered as protection scope of the present invention.
