Abstract
A thermally actuated valve is provided herein. The thermally actuated valve includes a valve fitting, a valve body, and a movement control mechanism. The valve fitting includes an active member to selectively activate based on an input. The valve body includes a passive wax member that moves between a passive contraction state and a passive expansion state based on a passive temperature. The movement control mechanism is disposed between the valve fitting and the valve body. The movement control mechanism controls movement of the valve body between an open state and a dosed state based on movement of at least one of the active member and the passive wax member.
Claims20
A thermally actuated valve comprising:
- a valve fitting including an active member to selectively activate movement of the thermally actuated valve based on an input;
- a valve body including a passive wax member to move between a passive contraction state and a passive expansion state based on a passive temperature;
- and
- a movement control mechanism disposed between the valve fitting and the valve body, the movement control mechanism to control movement of the valve body between an open state and a closed state based on movement of at least one of the active member and passive wax member.
A system comprising:
- at least one thermally actuated valve including:
- a valve fitting including an active member to selectively activate movement of the thermally actuated valve;
- a valve body including a passive wax member to move between
- a passive contraction state and a passive expansion state based on a passive temperature;
- and
- a movement control mechanism disposed between the valve fitting and the valve body, the movement control mechanism to control movement of the valve body between an open state and a closed state based on movement of at least one of the active member and passive wax member;
- and
- a power source connected to the active member, the power source to activate the active member based on an input.
A method to control a movement of at least one thermally actuated valve, the method comprising:
- providing the at least one thermally actuated valve including a valve fitting with an active member, a valve body including a passive wax member, and a movement control mechanism disposed between the valve fitting and the valve body, the movement control mechanism to control movement of the valve body between an open state and a closed state based on movement of at least one of the active member and passive wax member;
- selectively controlling the movement of one of the at least one thermally actuated valves using a heat source and an input, the movement based on the active member that selectively moves between an active contraction state and an active expansion state based on an active temperature provided by the heat source;
- and
- passively controlling the movement of the one of the at least one thermally actuated valve based on movement of the passive wax member that moves between a passive contraction state and a passive expansion state based on a passive temperature.
