Also settable gasket seal between the junction of body, to increase leakproofness.
In some embodiments, it is additionally provided in the corresponding position of upper cover 12 and lower cover 13 for being socketed third sealing ring 19
Third annular groove, the third annular groove in upper cover 12 is recessed inwardly along the radial direction of upper cover 12, on lower cover 13
Third annular groove be recessed inwardly along the radial direction of lower cover 13.
In conclusion in priming device provided herein, down-pressed pole moves down along the axial direction of pilot hole, with
Fluid hole is blocked, so that fluid injection cup be sealed, by liquid injection hole to injecting electrolyte inside fluid injection cup.Fluid injection is sealed in down-pressed pole
While hole, the axial direction by sealing bar along guide channel is moved, to the direction far from venthole to open venthole, from
And vacuum hole is connected with liquid-conveying ducts, the external vacuum equipment of vacuum hole, to be taken out under the action of vacuum equipment to battery
Vacuum.It can be seen that this priming device can vacuumize battery, while injecting electrolyte to fluid injection cup in this way, just
Fluid injection efficiency can be improved.The electrolyte that the venting channels being obliquely installed enable to remain in venting channels is back in battery
Electrolyte utilization rate had both can be improved in portion, also can avoid electrolyte leakage and pollutes environment.
The foregoing is a further detailed description of the present application in conjunction with specific implementation manners, and it cannot be said that this Shen
Specific implementation please is only limited to these instructions.For those of ordinary skill in the art to which this application belongs, it is not taking off
Under the premise of from the present application design, a number of simple deductions or replacements can also be made.
