Abstract
The present invention provides a gas safety device using low power to control high flow, which includes a controller, a differential pressure regulating valve, and a driver, the controller can control if the gas can flow into the differential pressure regulating valve, the differential pressure regulating valve is connected to the controller, and can control if the gas can flow out for burning according to the gas pressure changes, the driver uses a drive piece to drive a micro switch lever inside the controller, so that the controller can output gas, thus, the present invention can control high gas flow with low power while maintaining safe usage of the gas.
Claims14
A gas safety device using low power to control high flow, which includes:
- a controller, including a controller gas inlet and a controller gas outlet communicated with one end of the controller gas inlet, the controller gas inlet is connected to the gas source;
- a micro switch lever is movably configured on the controller gas inlet, and is connected to one end of the controller gas outlet, through the first valve portion on its one end, the controller gas inlet can be controlled to be or not to be communicated with the controller gas outlet;
- a differential pressure regulating valve, configured on one side of the controller, including a gas inlet flow channel, a gas outlet flow channel, a diaphragm that can be pushed by the gas pressure (i.e. back pressure), and a valve body configured on one side of the diaphragm, between the gas inlet flow channel and the gas outlet flow channel, a valve is configured, the gas outlet flow channel is connected to a gas burning appliance, the diaphragm is configured on one side of the gas outlet flow channel, the other side of the diaphragm is communicated with the controller gas outlet, one end of the valve body is configured with a second valve portion, the valve body goes through the valve gate, so that the second valve portion can shut the valve or open the valve, to control if the gas inlet flow channel can be communicated with the gas outlet flow channel;
- and
- a driver, configured with a drive piece that is connected to the micro switch lever, through displacement of the drive piece to drive the micro switch lever, the first valve portion can control if the controller gas inlet can be communicated with the controller gas outlet.
