Abstract
An automatic gas shutoff system for protecting the occupants of a home, apartment, RV, vehicle, etc. from dangerous levels of carbon monoxide. The automatic gas shutoff system generally includes one or more carbon monoxide detectors, a control unit, and a gas shutoff valve under the control of the control unit, so that the gas supply to a malfunctioning appliance can be shut off in the event it is creating dangerous levels of carbon monoxide within a protected space. The shutoff valve may have a manual reset feature that requires a problem condition to be repaired before the valve is manually reset to allow normal gas flow to resume.
Claims20
An automatic gas shutoff system, comprising:
- a gas shutoff valve having an inlet port and an outlet port, wherein the inlet port is fluidly connected to a gas inlet line, wherein the outlet port is fluidly connected to a gas outlet line, wherein the gas inlet line is fluidly connected to a gas source and wherein the gas outlet line is connectable to a gas appliance, wherein the gas shutoff valve has an open state that allows passage of gas and a closed state that prevents passage of gas, wherein the gas shutoff valve is normally in the open state;
- a first detector having an output, wherein the first detector is adapted to detect an environmental state of air in a room, and wherein the first detector is adapted to transmit an environmental state data based on the environmental state of air in the room;
- and
- a control unit in communication with the first detector to receive the environmental state data from the output of the first detector, wherein the control unit is in communication with the gas shutoff valve to control whether the gas shutoff valve is in the open state or closed state, wherein the control unit transmits a close signal to cause the gas shutoff valve to change from the open state to the closed state when the environmental state of the air in the room is determined to be in an unsafe state.

- a gas shutoff valve having an inlet port and an outlet port, wherein the inlet port is fluidly connected to a gas inlet line, wherein the outlet port is fluidly connected to a gas outlet line, wherein the gas inlet line is fluidly connected to a gas source and wherein the gas outlet line is connectable to a gas appliance, wherein the gas shutoff valve has an open state that allows passage of gas and a closed state that prevents passage of gas;
- wherein the gas shutoff valve is normally in the open state and wherein the gas shutoff valve comprises a manual reset;
- wherein the gas shutoff valve remains closed without a signal until it is manually reset;
- a first carbon monoxide detector having an output, wherein the first carbon monoxide detector is adapted to detect an environmental state of air in a room, and wherein the first carbon monoxide detector is adapted to transmit an environmental state data based on the environmental state of air in the room;
- a second carbon monoxide detector having an output, wherein the second carbon monoxide detector is adapted to detect an environmental state of air in the room, and wherein the second detector is adapted to transmit a second environmental state data based on the environmental state of air in the room;
- a smoke detector, the smoke detector having an output, wherein the smoke detector is adapted to detect an environmental state of air in the room, and wherein the smoke detector is adapted to transmit a third environmental state data based on the environmental state of air in the room;
- and
- a control unit in communication with the first detector to receive the environmental state data from the output of the first detector, wherein the control unit is in communication with the gas shutoff valve to control whether the gas shutoff valve is in the open state or closed state, wherein the control unit transmits a close signal to cause the gas shutoff valve to change from the open state to the closed state when the environmental state of the air in the room is determined to be in an unsafe state.
