Abstract
Embodiments of the invention are directed to systems and methods for automating the operation of a solenoid valve to prevent overheating of solenoid elements. The solenoid valve controls the flow of a fluid, such as gas, and may be automatically interrupted, or shut-off, of power upon the occurrence of fluctuating currents or other events. Once the problem has been removed or repaired, the flow of fluid through the solenoid valve may resume.
Claims20
A solenoid valve comprising:
- a valve body having a fluid inlet port and fluid outlet port;
- a fluid inlet passage having a first inlet end and a second inlet end, the first inlet end connected to the fluid inlet port and the second inlet end terminating having a “Y” configuration with a first leg connected to an orifice and a second leg connected to a safety mechanism;
- a fluid outlet passage having a first outlet end and a second outlet end, the first outlet end connected to the outlet port and the second outlet end connected to the orifice;
- a plunger slidably disposed within the valve body and movable between a closed position, where the plunger engages the orifice to block the flow of fluid through the outlet fluid passage, and an open position, where the plunger is distanced from the orifice to permit the flow of fluid through outlet fluid passage;
- a first solenoid coil surrounding the plunger and a first spring connected to the plunger;
- and
- a second solenoid coil surrounding a second spring connected to a locking pin mechanism for holding the plunger in the first, open position.
