The course of work of the present invention and operation principle：The present invention illustrates taking pneumatic boom hoisting as a example, during use, will
Source of the gas is connected on air inlet runner, will go out flow channel and be connected on pneumatic boom hoisting, when needing to supply to pneumatic boom hoisting, presses
Lower air inlet button, the pressing plate portion of air inlet button is pressed downward air inlet core body, and air inlet core body moves down, and (the first back-moving spring is compressed, air inlet
Caulking gum is separated from air inlet piston part, and now, air inlet runner is connected by plenum duct with passage, and source of the gas enters into branch chamber simultaneously
By venthole with go out flow channel and export pneumatic boom hoisting.
When pneumatic boom hoisting needs pressurize, cancel the pressing to air inlet button, now, air inlet core body is in the first reset
Move up under the reset response of spring, inlet seal rubber is contacted with air inlet piston part, inlet seal rubber is by plenum duct
Block, air inlet valve core reset completes.
Gas in pneumatic boom hoisting rests on pneumatic boom hoisting, branch chamber, goes out in flow channel and passage, gas
Dynamic boom hoisting gets off current state is static.
When needing to supply to pneumatic boom hoisting again, execute said process, and if now needing pneumatic lifting
When putting release, press release button, the pressing plate portion of release button is pressed downward exhaust gas core, and exhaust gas core moves down, the second reset bullet
Spring compress, exhaust choking portion be separated from venting piston part, venting runner connect, pneumatic boom hoisting, branch chamber, go out flow channel with
And the gas in passage, by exitting, runner is released, pneumatic boom hoisting release, when needing to stop release, cancels to putting
The pressing of gas button, now, exhaust gas core moves up under the reset response of second back-moving spring, inlet seal rubber with enter
Vent plug portion contacts, and plenum duct is blocked by inlet seal rubber, and exhaust gas core resets and completes.
The present invention can also adjust out the flow that flow channel exports gas, specifically, by controlling pressing air inlet button control
The air inlet core body amount of moving down processed, thus controlling the openings of sizes of plenum duct, when the opening of plenum duct is less, sends into out air-flow
The gas flow in road is less, therefore, can achieve that pneumatic boom hoisting slowly executes vertical motion, on the contrary if desired pneumatic lifting
When putting rapid increase, then, to lower limit, now, the opening of plenum duct is maximum, sends into out the gas of flow channel for pressing air inlet button
Flow is more, therefore, can achieve the rapid increase action of pneumatic boom hoisting.
The present invention can also adjust the flow that venting runner releases gas, specifically, by controlling pressing release button control
The air inlet core body amount of moving down processed, thus controlling the openings of sizes of venting runner, when the opening of runner of exitting is less, flows into bleed flow
The gas flow in road is less, therefore, can achieve that pneumatic boom hoisting slowly executes down maneuver, on the contrary if desired pneumatic lifting
When putting rapid decrease, then, to lower limit, now, the opening of venting runner is maximum, flows into the gas of venting runner for pressing release button
Flow is more, therefore, can achieve the rapid decrease action of pneumatic boom hoisting.
