Touching；Piston 5 moves downward until 432 block of block block of lower part retaining ring 43 is in the bottom of lower chamber 42.
Working principle is as follows: 9 driving stem 2 of cylinder moves upwards, thus drive sealing 21 and valve port 12 is separated and
Valve opening.Under valve opening state, grease type material enters in valve chamber 11 from feed inlet 13, then through water conservancy diversion gap 83 from valve port 12
It flows downward out, to carry out filling.After filling, 9 driving stem of cylinder makes sealing 21 seal up valve port 12 and close valve,
The bottom of valve rod 2 has the accumulation of grease type material.At the same time, gas passage 32 switches to exhaust condition, so that upper chamber
Gas in 41 is discharged through gas passage 32, and under the action of the elastic force of spring 6, piston 5 moves upwards so that lower chamber
Negative pressure is formed in room 42 and valve-rod cavity 22, the grease type material of the bottom section accumulation of valve rod 2 then can be under the action of negative pressure
The phenomenon that valve stem port 23 is sucked into valve-rod cavity 22, thus can effectively avoid 12 oil dripping of valve port generation.Due to valve-rod cavity sheet
The bore of body section 221 is greater than the bore of valve-rod cavity oral area section 222, therefore valve-rod cavity body section 221 is that sucking grease type material stays
There are enough accommodation spaces.When carrying out filling again, gas passage 32 switches to the state for being passed through compressed gas, upper chambers
Pressure in room 41 constantly increases, and piston 5 moves downward so that positive pressure is formed in lower chamber 42 and valve-rod cavity 22, in positive pressure
Acting on the grease type material in lower valve rod cavity 22 can be then discharged downwards by valve stem port 23, thus with the grease type object in valve port 12
Material flows out downwardly together.
The present invention has the advantages that one, structure is simple, ingenious, low manufacture cost.Two, filling to finish thickness, 2 bottom of valve rod
Grease type material can be inhaled into valve-rod cavity 22 from valve stem port 23, next time is discharged again when filling, this can not only effectively prevent
Only occur the phenomenon that oil dripping, the loss of material when avoiding grease type material from polluting bottleneck, while also can be reduced filling, thus effectively
Save production cost.Three, guide ring 8 is set in valve chamber 2, grease type material can be made to be in the form of a column outflow placed in the middle, this can be effectively improved
Filling effect.
