Abstract
A regulator includes a body, a first cage positioned in the body, a diaphragm positioned within the body, and a second cage operatively connected to the diaphragm. The body has an inlet, an outlet, and a passage formed between the inlet and the outlet and the first cage is positioned adjacent the passage. The second cage moves with the diaphragm and is positionable on a first side of the diaphragm, opposite the first cage, or on a second side of the diaphragm such that the second cage is positioned within the first cage and is movable relative to the first cage.
Claims20
A regulator, comprising:
- a body having an inlet, an outlet, and a passage formed between the inlet and the outlet;
- a first cage positioned in the body adjacent the passage and between the inlet and the outlet;
- a diaphragm positioned within the body;
- and
- a second cage operatively connected to the diaphragm such that the second cage moves with the diaphragm;
- wherein
- the second cage is positionable on a first side of the diaphragm, opposite the first cage, or on a second side of the diaphragm such that the second cage is positioned within the first cage and is movable relative to the first cage.
A trim assembly, comprising:
- a first cage having an outwardly extending flange and a plurality of first openings formed through the flange;
- and
- a second cage having a plurality of second openings formed radially through a cylindrical wall of the second cage;
- wherein
- the second cage is operatively connected to a diaphragm and is positionable on a first side of the diaphragm, opposite the first cage, for high flow applications and on a second side of the diaphragm such that the second cage is positioned within the first cage and is movable relative to the first cage for low flow applications.
A method of configuring a regulator, comprising the steps of:
- positioning a first cage in a body of the regulator between an inlet and an outlet of the regulator;
- operatively connecting a second cage to a diaphragm of the regulator;
- positioning the diaphragm in the body of the regulator such that the second cage is positioned within the first cage and is movable within the first cage when the regulator is being used in a low flow application;
- and
- positioning the diaphragm in the body of the regulator such that the second cage is positioned spaced apart from the first cage and on an opposite side of the diaphragm from the first cage when the regulator is being used in a high flow application.
