Abstract
The invention relates to the field of fuel oil system design of an airplane, in particular to an electrically-controlled fuel oil path conversion, filtering and cutting-off device. The device solves the problem that in an existing fuel oil system, a fuel oil selector, an oil filtering valve and an oil cutting-off valve cannot be integrated together, and consequently, a fuel oil system is complex in structure. According to the device, a driving shaft valve assembly controls a left oil supply pipeline or a right oil supply pipeline in a valve body assembly to be communicated with a third cavity, and therefore the conversion function of a fuel oil path is achieved; fuel oil enters a first cavity from the interior of a second cavity after being filtered through a filter screen, so that the filtering function on the fuel oil is achieved; in addition, when the driving shaft valve component rotates to the position allowing a third cavity to be not communicated with the second cavity, the cutting-off function is achieved. Therefore, the fuel oil selector, the oil filtering valve, the cutting-off valve and motors in the oil supply system are integrated, and the system is high in integration, smaller tin occupied space, lighter and higher in reliability.
