Abstract
Gas meters including a first portion and a second portion are provided. The first portion is separate and distinct from the second portion and a physical barrier is positioned between the first portion and the second portion. The first portion includes at least a motor associated with a shut-off valve for the gas meter and the second portion includes at least an area for a gas stream to flow through. Related gas regulating devices are also provided herein.
Claims10
A gas meter comprising:
- a housing comprising a first portion and a second portion, the first portion of the housing being separate and distinct from the second portion of the housing and a first physical barrier positioned between the first portion of the housing and the second portion of the housing, wherein the first portion of the housing comprises at least a motor associated with a shut-off valve for the gas meter;
- a valve housing positioned in the second portion of the housing, the shut-off valve being positioned in the valve housing in the second portion of the housing;
- a second physical barrier between the valve housing and the valve,
- wherein the first portion of the housing of the gas meter further comprises a gear box coupled to the motor;
- wherein the second portion comprises at least an area for a gas stream to flow through;
- and
- wherein the first and second portions of the housing of the gas meter are configured to fit together as a case and cover for the gas meter and provide a single contiguous unit;
- and
- a shaft that extends between the first and second portions of the housing of the gas meter, the shut-off valve being coupled to the motor through the shaft,
- wherein the first physical barrier comprises a barrier o-ring positioned around the shaft between the first and second portions of the housing and wherein the second physical barrier comprises an inner o-ring positioned around the shaft between the valve and the valve housing.

A gas regulating system comprising:
- a gas meter housing comprising a first portion and a second portion, the first portion of the housing being separate and distinct from the second portion of the housing and a first physical barrier positioned between the first portion of the housing and the second portion of the housing;
- a valve housing positioned in the second portion of the gas meter housing;
- a shut-off valve positioned in the valve housing;
- a second physical barrier between the valve housing and the shut-off valve;
- a motor in the first portion of the gas meter housing and coupled to the shut-off valve and configured to activate the shut-off valve responsive to a parameter indicating to shut-off gas flowing through a gas meter;
- and
- a shaft that extends between the first and second portions of the housing of the gas meter, the shut-off valve being coupled to the motor through the shaft,
- wherein the motor is physically separated from gas flowing through the gas meter;
- wherein the first and second physical barriers provide the physical separation between the motor and the gas flowing through the gas meter;
- wherein the first portion of the gas meter housing further comprises a gear box coupled to the motor;
- wherein the first and second portions of the housing of the gas meter are configured to fit together as a case and cover for the gas meter and provide a single contiguous unit;
- and
- wherein the first physical barrier comprises a barrier o-ring positioned around the shaft between the first and second portions of the housing and wherein the second physical barrier comprises an inner o-ring positioned around the shaft between the valve and the valve housing.
