Abstract
Official abstract text for this publication.
A first stage pressure regulator is provided. A valve body has an inlet and an outlet that define a pressure chamber therebetween. The valve body defines a pressure compensation chamber having an opening fluidly communicating the pressure compensation chamber with the surrounding water. The first stage pressure regulator comprises an inlet tubular union removably received into the inlet. A removable high pressure orifice body defines an orifice therethrough. The orifice body is carried by the valve body proximate the inlet. A valve seat is within the valve body.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of servicing a first stage pressure regulator; the method comprising: removing a removable high pressure orifice body from an inlet of a valve body; modifying the removable high pressure orifice body; reinserting the repaired orifice body into and on the inlet of the valve body. 2 . The method of claim 1 , wherein the step of modifying the removable high pressure orifice body may include machining a new diameter of a flow restriction orifice of the removable high pressure orifice body that is of greater diameter than an original diameter of the flow restriction orifice. 3 . The method of claim 1 , wherein the step of modifying may include replacing the removable high pressure orifice body with a second removable high pressure orifice body. 4 . The method of claim 1 , wherein the step of removing includes unthreading an inlet tubular union from the valve body. 5 . The method of claim 4 , wherein the step of removing includes allowing gravity to act on the removable high pressure orifice body such that the removable high pressure orifice body drops out of the valve body. 6 . The method of claim 1 , wherein the step of modifying the removable high pressure orifice body includes cleaning the removable high pressure orifice body. 7 . The method of claim 1 , wherein the step of modifying the removable high pressure orifice body includes machining sealing surfaces of the removable high pressure orifice body. 8 . The method of claim 1 , wherein the step of modifying the removable high pressure orifice body includes replacing an annular seal thereof. 9 . The method of claim 3 , wherein the step of replacing includes replacing the removable high pressure orifice body with the second removable high pressure orifice body having an orifice diameter different from an orifice diameter of the removable high pressure orifice body.
