Abstract
A gas pressure regulator regulates a pressure of a gas system. The gas pressure regulator includes a first chamber, a first diaphragm which separates the first chamber into a first compartment and a second compartment, a second chamber, with a second diaphragm separating the second chamber into a third compartment and a fourth compartment, the fourth compartment being connected to, and in communication with, the first compartment of the first chamber. A movement of the first diaphragm causes a corresponding movement of the second diaphragm, and a change in the volume of the fourth compartment.
Claims19
A gas pressure regulator for regulating a pressure of a gas system, the gas pressure regulator comprising:
- a first chamber;
- a first diaphragm separating the first chamber into a first compartment and a second compartment;
- a second chamber;
- a second diaphragm separating the second chamber into a third compartment and a fourth compartment, the fourth compartment being connected to, and in communication with, the first compartment of the first chamber;
- and
- a movement of the first diaphragm causes a corresponding movement of the second diaphragm that changes a first volume of the fourth compartment and a second volume of the third compartment.
A method for regulating a pressure of a gas system with a gas pressure regulator comprising:
- mounting a regulator with a first chamber, a first diaphragm, a vent breather valve and a safety cap on a pressurized system, the first diaphragm separating the first chamber into a first compartment and a second compartment, the vent breather valve being located in the first compartment and the safety cap sealing the first compartment;
- removing the safety cap while the pressurized system is operating;
- connecting a second chamber to the first chamber via an adaptor, the second chamber including a second diaphragm separating the second chamber into a third compartment and a fourth compartment, the fourth compartment being connected to, and in communication with, the first compartment;
- replacing the safety cap above the second chamber;
- and
- operating the pressurized system,
- wherein during operation of the pressurized system, a movement of the first diaphragm causes a corresponding movement of the second diaphragm that changes a volume of the fourth compartment.
A method for regulating a pressure of a gas system with a gas pressure regulator comprising:
- mounting a regulator with a first chamber and a first diaphragm, the first diaphragm separating the first chamber into a first compartment and a second compartment;
- connecting a second chamber to the first chamber, the second chamber including a second diaphragm separating the second chamber into a third compartment and a fourth compartment, the fourth compartment being connected to, and in communication with, the first compartment;
- and
- operating the pressurized system,
- wherein during operation of the pressurized system, a movement of the first diaphragm causes a corresponding movement of the second diaphragm that changes a volume of the fourth compartment.
