  • Fluid shutoff apparatus
    Patent number: 6907898
    Abstract: A fluid shutoff apparatus utilizes a float [121] of a float chamber [115] connected to a float-operated valve [113] to provide positive shutoff of fluid to a downstream load upon excessive flow from the fluid outlet [109] of the apparatus. The float-operated valve is shut when fluid discharge from the apparatus is greater than the flow rate from a flow-limiting valve [103] connected to a fluid inlet [107], decreasing the fluid level in the float chamber. The volume of the float chamber prevents inadvertent shutoff of fluid due to normal perturbations in flow to the load.
    Type: Grant
