Abstract
The present disclosure relates to a valve assembly for controlling flow. The valve body has an inlet end and an outlet end. A piston is positioned within the valve body and is movable between an open position to open the valve body and a closed position to close the valve body. A spring is mounted between the piston and a spring adjustment member. A portion of the spring adjustment member is accessible through the inlet end of the valve body so as to be engageable by a tool to facilitate rotation of the spring adjustment member to vary compression of the spring to set a spring pressure rating.
Claims20
A valve assembly for controlling flow from a pressurized source to a tank, the valve assembly comprising:
- a valve body having an inlet end and an outlet end, the valve body defining fluid passages for receiving fluid flow between the inlet and outlet ends;
- a piston mounted within the valve body to control the fluid flow, the piston being movable between an open position and a closed position;
- a cap member that mounts adjacent the inlet end of the valve body;
- a compensator device housed within the cap member, the compensator device being accessible through the inlet end of the valve body;
- a spring mounted between the piston and the compensator device, wherein the spring biases the piston toward the open position, wherein the spring is compressed when the piston moves to the closed position;
- and
- wherein the compensator device is configured to axially rotate relative to the cap member to vary compression of the spring to achieve a desired spring pressure rating.
A valve assembly for controlling fluid flow, the valve assembly comprising:
- a valve body having an inlet end and an outlet end, the valve body defining a chamber;
- a piston positioned within the valve body to open and close the valve body, the piston being movable between an open position and a closed position;
- and
- a spring mounted between the piston and a spring adjustment member, a portion of the spring adjustment member being accessible through the inlet end of the valve body so as to be engageable by a tool to facilitate rotation of the spring adjustment member to vary compression of the spring to set a spring pressure rating.
A valve assembly for controlling flow of liquid from a pressured supply into a tank, the valve assembly comprising:
- a valve body having an inlet end and an opposite outlet end;
- a piston operative to close the valve assembly in response to a rise in fluid back pressure when a predetermined liquid level is reached in the tank;
- and
- a spring mounted between the piston and a spring adjustment member, a portion of the spring adjustment member being accessible through the inlet end of the valve body so as to be engageable by a tool to facilitate axial movement of the spring adjustment member to vary compression of the spring to achieve a spring pressure rating.
