Abstract
A remotely actuated pilot valve provides for a pilot gas valve that includes safe lighting and complete shutoff capabilities in the event that the flame that is heating a thermocouple is extinguished, the pilot valve having a pilot flow interrupter to provide pilot gas only when initially opened. A heater system that utilizes such a pilot gas valve is provided as is a method whereby the pilot gas valve used in such a system can be remotely and electronically actuated when required. Remote actuation is accomplished by use of a solenoid that is incorporated within the valve design and which is controlled by a remote operator.
Claims12
A gas pilot valve that is remotely actuated via a wireless electromagnetic signal that is transmitted from an antenna, the valve comprising:
- a gas in port;
- a gas out port;
- a pilot burner gas out port;
- an electronically actuable solenoid, the solenoid comprising electromagnetic windings that are functionally adapted to create an electromagnetic field within the solenoid when the solenoid is electrically actuated via the wireless electromagnetic signal, and the solenoid further comprising a spring-loaded push pin and a spring that is used with the push pin, the push pin spring being disposed fully within the solenoid and further disposed to urge the push pin upwardly, the solenoid further comprising a spring-loaded push pin having an uppermost end that extends above the solenoid for manually actuated resetting of the seal via the uppermost end of the push pin;
- a seal, the seal being normally held in a first position where gas flows from the gas in port to the gas out port and movable to a lower casting seat in a second position to stop the flow of gas through the valve;
- an interrupter subassembly comprising an upper casting seat, an interrupter seal, a spring, and an upper disk;
- and
- means for remotely actuating the solenoid via either the wireless electromagnetic signal when the signal is received by an antenna or manually such that the push pin is urged downwardly by the actuated solenoid to reset the seal to the first position after the seal is in a second position where gas is prevented from flowing from the gas in port to the gas out port.
A gas pilot valve that is remotely actuated via a signal from a telephone land line comprising:
- a gas in port;
- a gas out port;
- a pilot burner gas out port;
- an electronically actuable solenoid, the solenoid comprising electromagnetic windings that are functionally adapted to create an electromagnetic field within the solenoid when the solenoid is electrically actuated via the signal from the telephone land line, and the solenoid further comprising a spring-loaded push pin and a spring that is used with the push pin, the push pin spring being disposed fully within the solenoid and further disposed to urge the push pin upwardly;
- a seal, the seal being normally held in a first position where gas flows from the gas in port to the gas out port and movable to a lower casting seat in a second position to stop the flow of gas through the valve;
- an interrupter subassembly comprising an upper casting seat, an interrupter seal, a spring, and an upper disk;
- and
- means for remotely actuating the solenoid via the telephone land line signal such that the push pin is urged downwardly by the actuated solenoid to reset the seal to the first position after the seal is in a second position where gas is prevented from flowing from the gas in port to the gas out port.
