Adjustable gas electromagnetic valve

An adjustable gas electromagnetic valve, comprising:

• a valve body having an inlet, an outlet, a first gas passageway, and a second gas passageway, wherein gas enters the valve body via the inlet and leaves via the outlet, and two ends of the first passageway and the second gas passageway respectively connect the inlet and the outlet;
• a gate member received in the first gas passageway to be moved between a first position, in which the gate member keeps the first gas passageway open, and a second position, in which the gate member keeps the first gas passageway closed;
• and
• an actuator connected to the gate member, wherein the actuator is activated by electrical signals to move the gate member;
• wherein the valve body has a chamber therein, the chamber forms a part of the first gas passageway and the chamber is wider than the rest part of the first gas passageway, and the actuator is received in the chamber;
• wherein the second gas passageway is straight from the inlet to the outlet, and the actuator is not received in the second gas passageway.
