The ball-type flameout protection gas valve for gas stoves is special in that there is a cover guide groove at the position where the sealing cover is opposite to the guide groove.

The ball-type flameout protection gas valve for gas stoves is special in that the guide groove in the valve chamber and the cover guide groove are semicircular in shape.

The ball-type flame-out protection gas valve for gas stoves described above is special in that the guide grooves in the valve cavity and the guide grooves in the cover are respectively square.

The ball-type flameout protection gas valve for gas stoves described above is special in that the guide groove is square.

The utility model is a ball-type flame-out protection gas valve for a gas stove. Due to the adoption of such a structure, when the gas channel needs to be opened, the valve needle moves forward, touches the ball, and moves the ball, and the ball pushes the push rod to overcome the pressure spring. The resistance enters the installation room of the solenoid valve through the vent hole, so that the solenoid valve core of the solenoid valve leaves the vent hole, then the gas enters the valve cavity, the igniter ignites, and when the thermocouple senses the flame, the solenoid valve is energized, and under the action of the pressure spring , the push rod is separated from the solenoid valve core of the solenoid valve; when the thermocouple cannot sense the flame, the solenoid valve is powered off, and the solenoid valve core of the solenoid valve closes the vent hole; there is an angle between the solenoid valve installation room and the valve cavity, which can The auxiliary air plate on the auxiliary nozzle is conveniently adjusted, which reduces the volume and the height of the gas stove; and in the manufacturing process, one mold is two pieces, which overcomes the defect of one mold one piece in the prior art. Therefore, it is not only small in size, can reduce the height of the gas stove, and the wind plate on the auxiliary nozzle can be effectively adjusted; and in the manufacturing process, one mold is two pieces.
