Projection is arranged on sealing ring body, with this body by integral forming of sealing ring.First projection is protruded to sealing ring center, and second
Projection is protruded to outside sealing ring, together with sealing ring body constitutes y-type structure.It is provided between first projection and the second projection
For bearing the groove of hydraulic oil.The groove has two effects：One is to be first raised and the second projection by external impacts
When, there is provided the space of elastic deformation, so as to absorb the energy of most of impact, do not allow sealing ring yielding, treat that external force disappears
After can return to the original form；Two is that the hydraulic oil in groove has certain pressure to the first projection and the second projection, makes sealing
Circle is brought into close contact with casing wall and piston rod, improves sealing property, it is ensured that hydraulic oil will not seepage.
Working process and principle of the present utility model are：Y type of the utility model using particular design on testing machine is close
Seal and beam, the sealing ring can absorb the impact energy produced when test specimen ruptures, and effectively extend the use longevity of sealing ring
, there is seepage so as to avoid the hydraulic oil in testing machine in life.The beam is set to rectangle, on base, with good
Damping, sound insulation and shock-absorbing capacity, the vibrations that can be produced when effectively absorption test machine works, hence it is evident that improve the steady of testing machine
Qualitative and reliability.Simple structure of the present utility model, easy for installation, long service life, later maintenance are simply easy, using this
The testing machine detection accuracy of device is high, detection efficiency is high.
Compared with prior art, the utility model has further the advantage that：
(1) the utility model can effectively buffer examination using the y-type seal ring of particular design with excellent sealing performance
Impact when part ruptures, prevents the hydraulic pressure oil seepage of testing machine.
(2) stable using testing machine of the present utility model, reliable operation, beam effectively can be produced absorption test machine
Raw vibrations and impact, reduce the noise in running, greatly improve the security of testing machine.
(3) sealing ring that the utility model is provided is good with the effect of fitting of casing wall, piston rod wall, long service life, effectively
Reduce the cost and number of times of later maintenance.
