Abstract
A dual-purpose fluid control valve for controlling the flow of fluid to separate systems supplied by the valve. The control valve includes a body having an inlet, a first outlet, and a second outlet. The valve further includes means for controlling a rate of fluid through one outlet based on a fluid demand at the outlet while controlling the rate of fluid flow through the other outlet.
Claims33
A dual-purpose fluid control valve comprising:
- a body that defines an orifice between a first chamber having a fixed volume and a second chamber having a fixed volume;
- a first fluid outlet in communication with the first chamber;
- a second fluid outlet in communication with the second chamber;
- means for controlling a rate of fluid through the second chamber based on a fluid demand at the second fluid outlet while controlling another rate of fluid flow from the first chamber to the first fluid outlet.

A valve, comprising:
- a valve body having a valve body wall defining an interior chamber having a longitudinal axis, the valve body wall further defining a first port, a second port and a third port, each in communication with the interior chamber, the valve body wall defining a sealing surface disposed within the interior chamber along the longitudinal axis to separate the first and second ports;
- and
- a flow controller moveably disposed within the interior chamber, the flow controller having a first component with an operating position that defines a minimum distance between the first component and the sealing surface, a second component of the flow controller having a varying distance relative to the sealing surface when the first component is in the operating position.

A valve for controlling the flow of water between a domestic supply and a fire protection system supply, the valve comprising:
- a valve body having a proximal end and a distal end:
- an inlet at the distal end of the body for connection to a water supply;
- a first outlet at the proximal end of the body for connection to a fire sprinkler system;
- a second outlet located between the inlet and the first outlet for connection to a domestic water system;
- and
- an inner surface defining an interior chamber and central longitudinal axis of the valve body, the inlet being centrally aligned with the central longitudinal axis and in communication with the central chamber to feed water into the chamber, the first outlet being centrally aligned along the central longitudinal axis and in communication with the interior chamber to supply water to the fire sprinkler system, the second outlet being disposed between the inlet and the first outlet centrally aligned along an axis perpendicular to the central longitudinal axis, the second outlet being in communication with the interior chamber for supplying water to the domestic water system, the inner surface further defining a sealing surface about the central longitudinal axis spaced at a fixed distance from the first outlet and a stop surface about the central longitudinal axis spaced at a fixed distance from the second outlet, the stop surface being spaced from the sealing surface so as to divide the chamber and separate the inlet and first and second outlets,
- a flow controller disposed within the interior chamber centrally aligned to the central longitudinal axis, the flow controller having
- a sealer including a head portion biased against the sealing surface and a shaft portion depending from the head portion, the shaft portion having a proximal and a distal end;
- an occluder disposed about the shaft portion of the sealer such that the occluder can translate between an initial position at the proximal end of the shaft and a final position at the distal end of the shaft, and
- a spring coupled to the shaft portion of the sealer so as to bias the occluder in the initial position, the spring having a compressed length to locate the occluder along the shaft portion of the sealer distal of the initial position.
