ABSTRACT:
A gas regulator with an adjustable safety device has a main body, and two pressure regulators inside the body to regulate the gas pressure inside the body at a stabilized value to flow to a gas stove or the like. The regulator also has a micro adjusting device to stop gas supply in case of large gas flowing such as gas leakage by a steel ball blocking up an end opening in a tube in the micro adjusting device, and the distance between the steel ball and the end opening in the tube can be adjusted to change sensitivity of the ball so as to acquire the best possible safety for gas leakage. A recovery unit is provided to recover the position of the ball from the end opening in the tube if the ball is sucked to block up the end opening in case of gas leakage.
