Operation principle of the present utility model:
The conducting of PLC Controlled by Programmable Controller air inlet film plate valve is inflated tire on setting drum, the internal pressure that pressure switch detects tire reaches after setting pressure, detection signal is fed back to PLC Programmable Logic Controller, PLC control air inlet film able to programme plate valve stops inflation, if inside tires pressure surpasses setting pressure, PLC Controlled by Programmable Controller air inlet film plate valve stops inflation, and control exhaust membrane plate valve is opened and carried out exhaust; If after being detected by pressure switch when inside tires pressure leakage or other reasons cause pressure, detection signal feeds back to PLC Programmable Logic Controller, PLC Controlled by Programmable Controller air inlet film plate valve is inflated, until the pressure balance of tire.
A kind of set-up mode of described air inlet film plate valve and exhaust membrane plate valve, air inlet film plate valve is directly connected in inflation gas circuit, and exhaust membrane plate valve is by the inflation gas circuit after exhaust branch road access air inlet film plate valve.
Further be designed to, described inflation gas circuit is communicated with tire by the air inlet air flue of (central authority) elevating lever inside on setting drum.
The scheme that described pressure switch detects tire internal gas pressure size is that pressure switch is communicated with tire by detecting gas circuit.
Further be designed to, described detection gas circuit is opened in the inside of (central authority) elevating lever on setting drum.
The beneficial effects of the utility model:
1, the utility model all steel giant embryo meridian forming machine setting drum pressure control device is simple in structure, and dismounting is easy to maintenance, and cost is low.
2, the utility model reduces difficulty of processing, and pressure controling precision is high, and inflation is fast.
3, the utility model is when stopping the supple of gas or steam, having a power failure, and the persistence of pressurize is higher than traditional proportioning valve.
4, the utility model is particularly suitable for the inflation requirements of large capacity tire.
