Operation principle：
Pneumatic operated valve is Q1Q2As shown in Figure 3, a, b, c are cylinder head and accordingly dock：A- and cylinder adapter T-phase are logical, b- and gas
Source air inlet connects, and c- is communicated with cylinder piston epicoele, N- and S on reversal valve2Connect J1、J2Communicated with the gas outlet of silencer two,
In valve during the off-load of Q1Q2 right chambers, valve inner carrier is closed because of spring effect, left chamber, and right chamber is open-minded；If N mouthfuls of air inlet, overcomes spring to make
Firmly, piston is pushed to limit on the left position, then close right chamber, opens left chamber and commutates.
Reversal valve as shown in Figure 3, S1Air inlet, S2Gas returning port, S0Airway in valve, S3- leakage port, when on cylinder piston
During row, reversal valve upper valve rod is clashed into by fender 4, pushes valve open, opens S1-→S2；When cylinder piston is descending, reversal valve lower valve
Bar is clashed into by fender 4, pushes valve open, opens S2-→S3。
Source of the gas is designated as P for compressed air0, P0-→K1It is air inlet-→ b- → Q1Middle a- → T- → e- → piston cavity of resorption is pushed away
The gas of piston ↑-piston upper chamber-→ C- → Q2Middle J2- → silencer-→ air；Due to piston stroking upward in place, S1-→S2Now,
P0-→K1-→d-→S1-→S2- → N- → Q valve elements are pushed to left end, open left chamber, close right chamber and reach commutation purpose, and b- →
A is closed, and b- → c is open-minded.
P0-→K1Gas-→ e- → T- → a- → the J of-→ b- → c- → push to piston ↓ piston cavity of resorption1- → silencer-→ big
Gas.Due to descent of piston in place, reversal valve lower valve rod is hit, and opens S2-→S0-→S3, reversal valve upper valve rod because of spring effect
Restore S1-→S2, now Q- → N- → S2-→S3- → air, pneumatic operated valve right chamber be in off-load, left end because of spring effect, its valve
Core is pushed to left end, so as to close left chamber, opens right chamber, is pumped once this completes cylinder.
