Abstract:
A fluid regulator includes a regulator body having a fluid inlet and a fluid outlet connected by a fluid flow path, with a portion of the regulator body forming a first chamber, an orifice disposed in the fluid flow path, a seat, and a control element disposed within the fluid flow path and shiftable between an open position spaced away from the seat and a closed position seated against the seat, with the control element arranged to respond to fluid pressure changes to control flow of a process fluid through the orifice. A diaphragm has a radially inner portion that is operatively coupled to the control element and a radially outer portion that is operatively coupled to the regulator body. The diaphragm includes a resilient redundant diaphragm sandwiched between two metal diaphragms, the diaphragm providing two separate seals.

Claim (Index 10):
A method of reducing leaks in a regulator, the method comprising:\n providing a fluid regulator having a regulator body including a fluid inlet and a fluid outlet connected by a fluid flow path, the regulator further having an orifice disposed in the fluid flow path, and a seat disposed in the orifice, a control element disposed within the fluid flow path, the control element being shiftable between an open position spaced away from the seat and a closed position seated against the seat, the control element being arranged to respond to fluid pressure changes to control flow of a process fluid through the orifice, and the regulator further having an actuator attached to the regulator body, the actuator being operatively coupled to the control element and arranged to respond to fluid pressure changes to move the control element between the open position and the closed position to control flow of the process fluid through the orifice; providing a first metal diaphragm; coupling a radially inward portion of the diaphragm to the control element; providing a second resilient diaphragm; providing a third metal diaphragm; and coupling a radially inward portion of the third diaphragm to the control element, wherein the second diaphragm comprises a resilient material and the second diaphragm is located between the first diaphragm and the third diaphragm.
