It is arranged on by helicitic texture in fixed plate 41；The locking nut is arranged on support 42, and locking nut is used for support 42
It is locked in fixed plate 41；The head of rotary handle 43 is helicitic texture, and rotary handle 43 is by being threadably mounted at support 42
On,；The pressing plate 44 is arranged on the end of rotary handle 43, and the bottom surface of pressing plate 44 is symmetrically installed with cylinder 45.On rotary handle 43
Helicitic texture can cause in work, and pressing plate 44 is safer to the pressure remained steady of pressure testing axle 2, the course of work.
The support 42 is connected through a screw thread in fixed plate 41, and support 42 can rotate around fixed plate 41, from
And pressing plate 44 can be made to deflect certain angle to deviate directly over pressure testing axle 2, pressure testing axle 2 is placed and taken out so as to convenient.Work
Before work, first swinging mounting 42, pressing plate 44 is removed directly over shell 1, vacating space in shell 1 is put into for pressure testing axle 2.
Rotation of the pressing plate 44 by rotary handle 43 on support 42, pressing plate 44 apply pressure to pressure testing axle 2 downwards.
During work, rotary handle 43 is rotated, rotary handle 43 moves downward close pressure testing axle 2 with dynamic pressure plate 44, and then cylinder 45 acts
Pressure testing axle 2 is tightly pushed down.
Mutual UNICOM between the cylinder 45, ensure that the pressure that pressing plate 44 applies to pressure testing axle 2 is balanced.
Specific workflow is as follows：
First, linked up one by one by thread spindle and screwed hole between multiple blocking modules 3 and form an entirety, then will be whole
The blocking module 3 of body is arranged in the cylindrical type groove of pressure testing axle 2, and during this, electromagnet 32 is powered, and blocks first 35 by magnetic force
Shunk to axle center, after installing, electromagnet 32 powers off, and each blocking first 35 blocks up liquid pass hole 21 in the presence of compression spring 33
Firmly.Then, swinging mounting 42, pressing plate 44 is removed directly over shell 1, then pressure testing axle 2 is slowly inserted in shell 1.Then
Support 42 is gone back to directly over pressure testing axle 2, rotary handle 43 is rotated and the small cylinder 45 on pressing plate 44 is firmly pressed pressure testing axle 2
On shell 1.Next, testing nethermost sealing ring first, now all liquid pass holes 21 slowly increase all in blocked state
The oil pressure entered from snap joint 6 in shell 1 is added to stop oiling immediately after pressure gauge 1 reaches rated pressure, in this mistake
Observe whether pressure gauge 29 numerical value occurs in journey, if pressure gauge 29 occurs without numerical value, show that sealing ring meets specified pressure
Power, pressure-resistant performance are qualified；Show sealing ring resistance to pressure if there is numerical value in pressure gauge during being slowly increased oil pressure 29
Can be unqualified, now stop oiling immediately, the nethermost electromagnet 32 for blocking module 3 is initially powered up, and blocks first 35 with crossing liquid
Hole 21 is separated, and the hydraulic oil in shell 1 is flowed out by nethermost liquid outlet, and pressure release is carried out to shell 1；Next detection reciprocal the
Two sealing rings, now, the nethermost electromagnet 32 for blocking module 3, which continues energization, makes blocking first 35 be separated with liquid pass hole 21,
Remaining blocking first 35 for blocking module 3 continues to block liquid pass hole 21, is at this moment slowly injected into hydraulic oil at snap joint 6 again,
Hydraulic oil comes second sealing ring by the liquid pass hole 21 of bottom, continues to be slowly increased oil pressure, exists in the numerical value of pressure gauge 1
During reaching rated pressure, whether observation penultimate pressure gauge 29 there is numerical value, and penultimate pressure gauge 29 is not
There is numerical value and then show that the pressure-resistant performance of sealing ring is qualified, by that analogy, complete the rated pressure detection of each sealing ring one by one.
The basic principles, principal features and advantages of the present invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, the original for simply illustrating the present invention described in above-described embodiment and specification
