Abstract
A pressure regulator assembly comprising: a regulator body having a housing, an inlet portion at one end of the housing and a cap at an opposite end of the housing, the inlet portion and the cap in substantially coaxial alignment along a regulator body axis; a pressure regulator module received in the housing, interposed between the inlet portion and the cap, with a pressure regulator module center axis inclined at an angle to the regulator body axis; the pressure regulator module incorporating a plunger movable toward and away from a valve seat in axial alignment with the plunger; a flow path passing through the plunger and in communication with the inlet portion and the cap; and wherein the cap is removable from the regulator body housing to provide access to the pressure regulator module.
Claims25
A pressure regulator assembly comprising:
- a regulator body having a housing, an inlet portion at one end of said housing and a cap at an opposite end of said housing, said inlet portion and said cap in substantially coaxial alignment along a regulator body axis;
- an interchangeable pressure regulator module received in said housing, interposed between said inlet portion and said cap, with a pressure regulator module center axis inclined at an angle to said regulator body axis;
- said pressure regulator module incorporating a plunger movable toward and away from a valve seat in axial alignment with said plunger;
- a flow path passing through said plunger and in communication with said inlet portion and the cap;
- and
- wherein the cap is removable from said regulator body housing to permit removal and repair or replacement of said pressure regulator module.
A pressure regulator assembly comprising a regulator body having a housing, an inlet portion at one end of said housing and a cap at an opposite end of said housing, said inlet portion and said cap in substantially coaxial alignment along a regulator body axis;
- a pressure regulator module received in said housing, interposed between said inlet portion and said cap, with a pressure regulator module center axis inclined at an angle to said regulator body axis, said pressure regulator module incorporating a plunger moveable toward and away from a valve seat, a liner provided with upper and lower chambers separated by a diaphragm extending radially between said plunger and said liner, and a spring bearing said plunger in a downstream direction;
- and
- a valve seat located at one end of a valve body that is located opposite an upstream edge of said plunger.
A pressure regulator assembly comprising:
- a regulator body having a housing, an inlet portion at one end of said housing and a cap at an opposite end of said housing, said inlet portion and said cap in substantially coaxial alignment along a regulator body axis;
- an interchangeable pressure regulator module received in said housing, interposed between said inlet portion and said cap, with a pressure regulator module center axis inclined at an angle to said regulator body axis;
- said pressure regulator module incorporating a plunger movable toward and away from a valve seat in axial alignment with said plunger;
- a flow path passing through said plunger and in communication with said inlet portion and the cap;
- wherein said valve seat is located at one end of a valve seat body that is located opposite an upstream edge of said plunger;
- and
- wherein said valve seat body is moveable such that said valve seat is caused to move into engagement with a lower edge of said plunger to thereby shut off all flow through said regulator body.
