The invention provides a pressure control system of an airplane air source vehicle. The pressure control system can solve the problems that a pressure control system of an existing airplane air source vehicle is complex and high in running cost. The pressure control system comprises an air supply pipeline and a state selecting switch. The state selecting switch is provided with an airplane start state contact and an air adjustment state contact. The air supply pipeline is provided with a control air output connector and an overflow valve connector. The control air output connector is connected with a first electromagnetic valve and a pressure control valve through a pipeline, and the first electromagnetic valve is sequentially connected with a pressure control valve, a second electromagnetic valve and an overflow valve through a pipeline. The overflow valve communicates with the overflow valve connector. A differential pressure switch is arranged at the position, close to the overflow valve connector, of the air supply pipeline. The airplane start state contact of the state selecting switch is connected with a relay KA2 in an electric control manner. The air adjustment state contact is connected with a relay KA1 in an electric control manner. The differential pressure switch is connected with the first electromagnetic valve through the relay KA1 in an electric control manner, and the differential pressure switch is connected with the second electromagnetic valve through the relay KA2 in an electric control manner.
Description
technical field [0001] The invention relates to the field of pressure control systems, in particular to the field of pressure control systems for aircraft air source vehicles, in particular to the pressure control system for aircraft air source vehicles. Background technique [0002] The aircraft air source vehicle is driven by a vehicle-mounted water-cooled diesel engine with a dry-screw compressor to generate powerful compressed air to assist various large and medium-sized aircraft and related military aircraft ground start-up equipment. Usually, the aircraft air source vehicle needs to output two levels of compressed gas with different pressures of "aircraft start" and "air conditioning" for the use of the aircraft. The current air source vehicle uses two pressure regulating valves to control the two levels of pressure respectively. The pipeline is complex, the control system has many joints and leakage points, and the control uses more solenoid valves, so the control sys...
