Abstract
diaphragm float valve with transient mitigator for use in a water tank. The float valve comprises at least one inlet (23) and outlet (21), and a sealing member (41) that controls water flow between the inlet and outlet; a hinged lever (50) with a buoyant device (60) located at the end of the hinged lever; and a biasing means (51) to control the movement of the hinged lever. The biasing means provides a delay in the movement of the hinged lever in order to prevent repeated oscillations, in response to changes in water level of the tank. The delayed movement of the hinged lever prevents immediate opening and closing of the valve. Constant changes in water flow introduce transients into the pipe network, leading to accelerated pipe wear. The proposed invention provides a float valve that can mitigate transients with a biasing mechanism.
Claims (10)
1. A diaphragm float valve with transient mitigator for use in a water tank comprising of: a. at least one inlet and outlet that allows water to communicate through the float valve; b. a sealing member that controls a water flow between the inlet and outlet; c. a hinged lever connected to the float valve; d. a buoyant device that is located in a water tank; e. wherein the buoyant device is located at the end of the hinged lever; f. a biasing means to control a movement of the hinged lever by providing a delay in the movement of, and preventing repeated oscillation of said hinged lever, in response to a change in a water level in the tank; and g. wherein delayed movement of the hinged lever prevents immediate opening and closing of the valve.
2. The float valve as in claim 1, wherein the biasing means is a spring.
3. The float valve as in claim 1, wherein the biasing means is a gas strut.
4. The float valve as in claim 1, wherein the biasing means is a cam.
5. The float valve as in claim 1, wherein the hinged lever further comprises a cover.
6. The float valve as in claim 1, wherein the outlet comprises of vanes in an outlet orifice.
7. The float valve as in claim 1, wherein the sealing member further comprises of a hole that allows water to pass through and clean the float valve.
8. The float valve as in claim 7, wherein the sealing member is made of a flexible material.
9. The float valve as in claim 7, wherein the hole can allow fluid to travel through the float valve to assist in cleaning internal components of the valve.
10. The float valve as in claim 1, wherein the sealing member operates in response to a pressure differential between a front chamber and a rear chamber of the valve.
