10 lower QI KOU 14, form QI KOU 15 on the top of piston rod 12, with connect lower air chamber 10 with it is extraneous；The piston rod 12
Outside is socketed with a upper vapour chamber 7 of connection and extraneous trachea 16, and the trachea 16 is passed through in the upper air cavity 7 of the insertion of cylinder plug 2, trachea 16
Gap is left between piston rod 12 with ventilating air, upper end and the outer wall of piston rod 12 of trachea 16 are tightly connected and in trachea 16
Air inlet 17 is provided with the wall of side, the outer wall of trachea 16 is sealed slidingly against with cylinder plug 2 by sliding sleeve 22 and is connected 7, and sliding sleeve 22 is fixed
It is arranged in cylinder plug 2.
When cylinder barrel 1 is relatively large in diameter, cylinder 1 may be selected integral type, spacing block is directly welded inside cylinder 1, to carry
The globality of high enterprise's damped cylinder cylinder barrel outer wall, improves sealing effectiveness.
In actual design and production, spacing block is double polarizing keys structure small in ends broad in the middle, two ends boss respectively with it is upper
The inner wall sealing connection of cylinder 1-1 and lower shell 1-2, the diameter of mid portion and the diameter phase of upper shell 1-1 or lower shell 1-2
Together, it is beneficial to cleaning, reduces the knuckle of gas-liquid damping cylinder outer surface, is beneficial to cleaning.
On above-mentioned spacing block 6, in two passes 11 one-way throttle valve 18, the setting of two one-way throttle valves 18 are respectively arranged with
In opposite direction, one-way throttle valve 18 is used to adjust the flow velocity of hydraulic oil, piston rod 12 is lifted with steady.
The groove 19 with diameter greater than the external diameter of trachea 16 is provided with the lower surface of cylinder plug 2, the groove 19 is same with trachea 16
Axle is arranged, and makes to form gap between trachea 16 and cylinder plug 2, and the lower end of the trachea 16 is fixed with the upper end face seal of upper piston 4 and connected
Connect, on the lower sides of trachea 16 gas outlet 21 is provided with, the depth for being smaller than groove 19 of the gas outlet 21 and upper piston 4,
When move on upper piston 4 be affixed with the bottom surface of cylinder plug 2 when, gas outlet 21 be located at gap in, prevent gas outlet 21 to be blocked.
Two nuts 22 are threaded with the upper end outer wall of the trachea 16, for the fixation of piston rod 12.
The lower end of the piston rod 12 flushes with the lower surface of lower piston 5, prevents bottom 3 from damaging because of the impact of the lower end of piston rod 12
Evil.
Operation principle of the present utility model is：Because air inlet pipeline is arranged on piston rod 12 and trachea 16, therefore
When using, the upper end of trachea 16 is fixed on other supports, when the air inlet of upper QI KOU 15, gases at high pressure enter lower air chamber 9, lower air chamber
9 expansions, promote cylinder barrel 1 to move down, and the hydraulic oil in lower oil cavitie 9 enters passage 11, and to one-way throttle valve 18 pressure is applied, by
It is oppositely arranged in two one-way throttle valves 18, therefore, the one-way throttle valve 18 in a passage 11 is had by hydraulic oil promotion
Open, enable hydraulic oil to flow into upper oil cavitie 8 from the passage 11, and upper air cavity 7 is while reducing, internal gas pass through air inlet
Mouth 17 is discharged；
In the same manner, when 17 air inlet of air inlet, above-mentioned action is contrary.
Due to the same one end of upper QI KOU and air inlet in gas-liquid damping cylinder, and gas-liquid damping cylinder outer surface structure is simple,
Therefore, cleaning gets up very convenient, but also drastically increases the gas-liquid damping cylinder on the centrifugal machine scraper device just
Victory.
