Abstract
A method and apparatus for a manual gas valve. The manual gas valve may include at least one internal spring and a valve plug. The internal spring may be independent from an external spring and a valve stem. The internal spring may be positioned in a constant installed height. The internal spring includes a constant spring force applied to the valve plug. The one or more manual gas valves may be used in a variety of applications.
Claims20
A gas range appliance comprising:
- one or more gas burners;
- at least one gas manifold;
- one or more manual gas valves configured to be positioned between an opened configuration and a closed configuration;
- at least one of the one or more manual gas valves having a valve stem, a valve plug, an internal spring, and a valve housing, wherein the internal spring includes a first spring force against the valve plug within the valve housing, and the at least one manual gas valve is in fluid communication with the at least one gas manifold and the one or more gas burners when in the opened configuration and is out of fluid communication with the one or more gas burners in the closed configuration;
- and
- wherein the first spring force is the same when the at least one manual gas valve is in each one of the opened configuration and the closed configuration.
3 more elements
A gas range appliance comprising:
- a valve housing having a cap and a plug housing;
- a valve plug and an internal spring positioned within the valve housing;
- a valve stem extending through the cap and into the valve housing to rotate the valve plug relative to the valve housing between an opened position and a closed position;
- and
- an external spring engaging the valve stem;
- wherein the internal spring includes a first end and a second end, wherein the first end engages the valve plug and the second end engages the cap to apply a constant force against the valve plug independent of both the opened position and the closed position of the valve stem.
3 more elements
A gas range appliance comprising:
- a gas valve comprising:
- a valve housing having an inlet and an outlet;
- a valve plug configured to rotate within the valve housing wherein the inlet is in fluid communication with the outlet in one or more rotational positions of the valve plug;
- one or more internal springs positioned in a constant installed height and engaging the valve plug within the valve housing;
- and
- a valve stem operably engaging the valve plug through the valve housing to selectively control the one or more rotational positions of the valve plug.
