摘要： A pressure control system and means for pressure pouring of cast steel wheels, comprising a control system and a main gas circuit. The control system comprises an upper computer, a PLC unit, a sensor, an operation box and an electronic valve. The upper computer is connected via a signal line with the PLC unit which is connected with each of the sensor, the operation box and the electronic valve. The sensor comprises an inside-tank pressure sensor and an inside-mold liquid level detecting sensor. The electronic valve comprises a quick breaking valve and a servo valve. The main gas circuit comprises a gas pressure bag, a ball valve, a pressure reducing valve, a solenoid valve, and a pressure tank. The gas pressure bag, the ball valve, the pressure reducing valve, the solenoid valve and the pressure tank are connected with one another via gas tubes.
