This utility model discloses a
safety control switch device for gas appliances, relating to the field of gas
equipment safety control technology. The device is installed on the gas inlet
pipe outside the gas appliance and includes a power supply, a
timer, a confirmation button, a
solenoid valve, an indicator light, an inlet
pipe, an outlet
pipe, and a housing. The power supply is a
dry cell battery. The
timer is connected to the power supply to set the
conduction current time. The confirmation button is connected to the
timer. The
solenoid valve and indicator light are respectively connected to the confirmation button. The inlet pipe connects the gas source to the
solenoid valve, and the outlet pipe connects the solenoid valve to the gas appliance. In use, the time is set by rotating the timer knob. After confirming safety, the confirmation button is pressed, causing the solenoid valve to open and the indicator light to illuminate, allowing gas to enter the gas appliance through the device. After the timer expires, the timer disconnects the circuit, the solenoid valve closes, and the indicator light goes out. This device facilitates maintenance and repair, ensures safe use of the gas appliance under supervision, and improves usage safety.
