Abstract

The invention relates to the technical field of heavy oil engine gas-assisted fuel oil supply, and particularly discloses a low-power-consumption driving gas metering valve for heavy oil piston enginefuel oil gas-assisted injection. The electromagnetic valve is composed of a shell, a magnetic conductive cover, an armature, a fixed magnet core, a valve seat, a valve element, a magnetic conductivesleeve, a wire frame, an electromagnetic coil, a valve element connecting rod and other components. The electromagnetic coil is directly positioned on the peripheries of the fixed magnet core and thearmature, meanwhile, a sealing assembly is additionally provided for sealing so as to prevent leakage of oil and gas, through the design, magnetic force lines generated by the electromagnetic coil cancompletely act on the fixed magnet core and the armature so that the valve can obtain stronger electromagnetic attraction force, then the metering valve can be controlled to be closed or opened by adopting the relatively low driving power, the driving power of the metering valve is reduced, the reliability of the metering valve can be improved, the service life of the metering valve can be prolonged, meanwhile, the total power consumption of an application system is reduced, and then the flight time of an aviation unmanned aerial vehicle is prolonged.

Description

technical field [0001] The invention belongs to the technical field of gas-assisted fuel supply for heavy oil engines, in particular to a low-power-consumption driven gas metering valve for fuel gas-assisted injection of heavy oil piston engines. Background technique [0002] At present, due to the requirements of equipment safety and fuel supply specifications, aviation drones all use heavy oil piston engines as flight power. Due to the high viscosity of heavy oil and poor atomization characteristics, an injection metering valve capable of atomizing heavy oil is required to complete the fuel supply for piston engines. At present, the air-assisted metering valve has good atomization ability, but its driving power is so large that it increases the power consumption of the equipment system and affects the endurance of the equipment. In the existing gas-assisted metering valve, there is generally a magnetic isolation sleeve between the electromagnetic coil and the fixed magnet...
