Abstract
A valve including a valve body; an adjusting assembly having an actuating portion and a regulating part; a flood prevention device at least partly located in the valve body, with the flood prevention device having a regulating portion; and a relief aperture defined through a wall of the regulating part to assist in reducing pressure on the regulating portion when the regulating portion moves to a closed position.
Claims18
A valve, comprising:
- a valve body;
- an adjusting assembly having an actuating portion and a regulating part, wherein the regulating part includes an aperture defined therethrough;
- a flood prevention device at least partly located in the valve body, the flood prevention device having a regulating portion located within the aperture of the regulating part;
- and
- a relief aperture defined through a wall of the regulating part, the relief aperture being in fluid communication with the aperture of the regulating part to assist in reducing pressure on the regulating portion when the regulating portion has moved to a closed position;
- wherein, as the pressure on the regulating portion is reduced, the regulating portion resets to allow fluid to flow through the valve;
- and
- wherein the regulating portion includes an inlet aperture and one or more side apertures.
5 more elements
A method for operating a flood prevention device in a valve, the method comprising:
- allowing a regulating portion of the flood prevention device to move from an open position to a closed position in response to a predetermined fluid rate;
- moving the regulating portion from a first position to a second position within a valve body, with the assistance of an actuating portion, to reduce a pressure on a regulating part, the regulating part having an aperture defined therethrough and the regulating portion being positioned within the aperture of the regulating part;
- and
- allowing the regulating portion to return from the closed position to the open position as fluid drains from a relief aperture defined through a wall of the regulating part, the relief aperture being in fluid communication with the aperture of the regulating part to assist in reducing the pressure on the regulating portion when the regulating portion has moved to the closed position;
- wherein, as the pressure on the regulating portion is reduced, the regulating portion resets to allow fluid to flow through the valve;
- and
- wherein the regulating portion includes an inlet aperture and one or more side apertures.
