  • Patent number: 8991415
    Abstract: A fire hydrant break off valve includes an offset pivot and a lateral trigger captured between a fire hydrant and fire hydrant break off riser. When a collision breaks the break off bolts holding the fire hydrant to the hydrant break off riser, the lateral trigger is released and the valve rotates to a closed position. Force of water attempting to escape rotates the valve around the offset pivot. The edge of the valve is tapered and after rotating, the valve is pushed against a matching seat to close the valve. The match of the tapered valve against the tapered seat stops or nearly stops all flow of water from the broken hydrant.

By forming the gearbox as a single piece as well, the entire actuator can be made as three major pieces. Optionally, the gearbox can be formed with cylindrical fittings which press-fit over pins on the valve, replacing the conventional mounting bracket.

  • Patent number: 8727310
    Abstract: Packing followers for use with valves are described. An example packing follower for use with a valve includes a body having an elongated portion and a bore therethrough to receive a shaft. A portion of the bore is tapered to exert a force on a retainer that at least partially surrounds and is positioned within a groove of the shaft when the shaft moves toward an opening defined by the body. Additionally, the force has a first component in a direction perpendicular to a longitudinal axis of the bore and a second component smaller than the first component in a direction parallel to the longitudinal axis of the bore.

  • Patent number: 8720414
    Abstract: Throttle body assemblies having improved throttle position sensing assemblies and a method of integrating a throttle position sensor assembly with a throttle body assembly are described. The method comprises the steps of: i) press-fitting a sensor element onto a shaft of a throttle plate of a throttle body assembly; ii) engaging one or more inwardly extending members of the sensor element with one or more recessed portions formed on the shaft of the throttle plate; and iii) disposing an inductive rotary position sensor proximate the sensor element, wherein the press-fit engagement and one or more inwardly extending members limit axial and rotational movement of the sensor element with respect to the throttle plate, and wherein the inductive rotary position sensor detects a relative position of the sensor element for the purpose of ascertaining a position of the throttle plate.

  • Publication number: 20140084201
    Abstract: A tri-eccentric valve with a symmetric drain-proof ring includes a valve body, a stem, a valve disk, a waterproof washer, and a drain-proof ring. The valve disk is formed as an asymmetric conical shape. The drain-proof ring is an O ring and is arranged in a stepped recess of the valve disk to seal the waterproof washer; the drain-proof ring is symmetric to the axis of the ring. In assembly state, a periphery of the drain-proof ring resists against an inner wall of the annular seat. The drain-proof ring is symmetrical and thus is easy to be installed to the valve disk without to align the drain-proof ring to a specific angle. Furthermore, it can be designed by computers and is manufactured by machines. When dirt accumulates on the drain-proof ring, it can remove the dirt by directly rotating the drain-proof ring.

  • Patent number: 8662099
    Abstract: An example valve shaft apparatus includes a shaft having a stationary seal and a dynamic seal spaced from the stationary seal. The stationary seal defines a first leakage detection area adjacent the stationary seal and the dynamic seal defines a second leakage detection area adjacent the dynamic seal. A seal leakage detector is integrally formed with the shaft to provide a visual indication of process fluid leakage within the first leakage detection area or within the second leakage detection area. The seal leakage detector has a passageway in fluid communication with the first leakage detection area and the second leakage detection area. The passageway has a cross-sectional profile that changes between the first and second leakage detection areas to prevent fluid from flowing from one of the leakage detection areas into a body of the fluid valve.
