Patent ID: 10197221

Abstract:
A cryogenic liquid switching system including an electronic control mechanism; a solenoid valve communicatively connected to the electronic control mechanism via an interface cable; a gas input control connected to the solenoid valve; and a pair of pneumatic valve actuators connected to the gas input control via separate isolation tubing components The system also including a pair of valve actuator pins, one each connected to a respective one of the pair of pneumatic valve actuators; a pair of pneumatic valves, one each connected to a respective one of the pair of valve actuator pins; and a cryogenic liquid input in fluid communication with at least a portion of each of the pair of pneumatic valves. The system further including a first cryogenic liquid output in fluid communication with a first of the pair of pneumatic valves; a second cryogenic liquid output in fluid communication with a second of the pair of pneumatic valves; and a temperature probe positioned adjacent to an exit of the cryogenic liquid input to measure the temperature of an incoming cryogenic liquid and send a signal to the electronic control mechanism to open and close the pneumatic valves based at least in part on the temperature of the incoming cryogenic liquid.
