The invention discloses an electromagnetic valve with two fuel gas flow capacity conditions. The electromagnetic valve comprises a valve body, a gas inlet joint, a gas outlet joint and a sealing gasket, wherein the gas inlet joint and the gas outlet joint are arranged on the valve body; the sealing gasket can move up and down. The electromagnetic valve is characterized in that a main channel and a leaking hole are formed in the gas outlet joint; the sealing gasket corresponds to the main channel. During working, the leaking hole is under an opening condition all along, the opening and closing of the main channel is realized by the up-and-down motion of the sealing gasket, so that switching the two fuel gas flow capacity conditions is realized. According to the electromagnetic valve disclosed by the invention, the main channel and the leaking hole are formed in the gas outlet joint, so that the function that switching the two fuel gas flow capacity conditions is electrically controlled is realized, and the structure is simple; when the electromagnetic valve is used, a user just need to connect the electromagnetic valve with a gas path in series, the gas path does not need to be additionally arranged, the structural change is low, and the increased cost is low.
