The operation principle of precise pneumatic control device：
As shown in Fig. 2 compressed gas enter in air inlet from the fast plug of air inlet 401.When air pressure exceed back-moving spring
Pretightning force, piston 301 and plug 302 are backed down by gas.Piston 301 is pressed on diaphragm 205；Plug is from gas passage orifices 310
Position remove, air inlet is turned on gas outlet and gas positioning pipe 501.One tunnel compressed gas entered gas outlet, fast from giving vent to anger
Plug 401 enters working cell.End surface of step hole sealing in plug and piston cylinder seat 302 cavity, now gas cannot be from letting out
QI KOU 307 is excluded.
Another road compressed gas, from gas positioning pipe 501, through after piston cylinder seat 302, feedback unit, enter frequency and adjust
In the adjustment seat 102 of whole unit 100.Outlet due to gas positioning pipe 501 is communicated with the helicla flute of flow tab 103, pressure
Gas adjustment passage between flow tab 103 and starboard trimtab 105 for the contracting gas, enters gas dome 204.Gas flows through
Gas dome 204 gas outlet, pressure acts on diaphragm 205.When the air pressure of gas dome 204 and the pretension of back-moving spring 304
When pulling force sum is more than the air pressure of air inlet, diaphragm 201 promotes piston 301 to move, and drives plug 302 mobile, confining gases
Access opening 320.
Now, plug 303 moves down, and leaves seal face, leakage port 307 and air conducting.Moment gas passage 310
Compressed gas from gas distribution hole 320, the gap between plug and piston cylinder seat 302 cavity, finally by leakage port 307
Flow out, pressure greatly reduces, the gas pressure of gas dome 204 also and then reduces simultaneously, compressed air overcomes back-moving spring 304 He
The pressure of diaphragm 205, backs down plug 303, and compressed air flows into gas passage 310, starts next cycle of operation.
Gap between flow tab 103 and starboard trimtab 105 is adjusted by flow adjusting screw 101, thus controlling
The gas of gas dome 204 processed flows into speed, thus controlling the time interval of circulation.
In the present embodiment, gas positioning pipe 501 is not required.Compressed gas pass sequentially through the gas of piston unit 300
Body access opening 310, the gas passage orifices 210 of feedback unit 200, finally enter in frequency adjustment unit 100 and can achieve.Setting
Gas positioning pipe 501 is the generation in order to prevent gas leak phenomenon that may be present between all parts.
Certainly, the gas passage that gas positioning pipe 501 is formed, can pass through in different all parts, be separately provided pipeline.
Gas positioning pipe 501 passes through the size that the design of each part is to reduce whole device, reduces the space taking.
