Split refueling valve jointly controlled by diaphragm and electromagnetic valve

The invention belongs to the field of mechanical structure design, and particularly relates to a split refueling valve jointly controlled by a diaphragm and an electromagnetic valve. The split refueling valve comprises a main valve assembly, a main valve spring, a self-sealing valve assembly, a channel shell, an oil return pipe connector, a diaphragm assembly, a diaphragm cavity spring, an electromagnetic valve, a handle, a micro-switch and a control shell. When a control assembly is detached and replaced as an independent LRU, leakage of a main valve cannot be caused. When an actuating circuit is not powered on, the electromagnetic valve is in a closed state, the fuel pressure acting on the two sides of the diaphragm assembly is balanced, and the main valve of the refueling valve should be closed or kept in the closed state. When the actuating circuit is powered on, the electromagnetic valve is opened, pressure difference is formed at an inlet and an outlet of the control assembly of the refueling valve, and
