  • Publication number: 20110260086
    Abstract: Valve shaft apparatus are described herein. 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.

    Abstract: A fluid control valve includes a housing defining therein a fluid passage. The fluid control valve further includes a valve member for controlling a fluid flow in the fluid passage by communicating and blocking by the fluid passage. The fluid control valve further includes a protection member being press-inserted into the housing for protecting the housing from heat of the fluid flow in the fluid passage. The housing is formed by die casting of an aluminum material. The protection member and a wall surface, which defines the fluid passage in the housing, define therebetween a thermal insulating layer for restricting thermal transmission of the fluid flow from the protection member toward the housing.

The damper includes an annular frame or frame and a flexible seal member that extends around an inner surface of the frame. The seal member is at least partially embedded or integrated into the frame and includes an exposed surface. The seal member can be a single or multi-component seal member. A rotatable shaft extends across the interior annular aperture of the annular frame, and a blade is coupled to the shaft. The blade that is attached to the shaft is rotatable between closed and open positions. An outer circumferential edge of the blade engages the exposed surface of the seal member when the blade is rotated to a closed position thereby forming an air tight seal.

  • Publication number: 20090001308
    Abstract: A valve to shaft assembly includes a butterfly-type valve, a pair of bushings receiving the valve and holding the valve in axial position within a housing, and a shaft engaging the valve and the bushings and rotating the bushings in the housing. The bushings include features to hold the valve in position in the bore prior to assembly of the valve and, furthermore, act as rotating bearing surfaces for the valve. The valve to shaft assembly process may be simplified, especially where multiple valves are assembled to a single common drive shaft, such as in a port face charge motion control valve. Furthermore, the valve to shaft assembly provides an axial degree of freedom between valve, drive shaft, and bore, which allows the valve to float on the axis of the drive shaft, to facilitate self centering of the valve in the valve housing.

  • Patent number: 7387291
    Abstract: The present invention provides a collapsible shaft and control assembly that is useful for transferring rotational control valve movements to a control surface. The invention includes a housing, shaft, and actuator arm. The housing defines a hollow cylinder. The shaft has a resilient end with a plurality of flexible strips capable of radial bending so as to transition between an expanded position and a compressed position. The shaft is positioned in the hollow cylinder, in the expanded position, so that the shaft can rotate. The actuator arm is positioned within the resilient end of the shaft so as to maintain the resilient end of the shaft in the expanded position. Both the actuator arm and shaft include reciprocal engagement means, and the actuator arm and shaft are positioned so as to engage the reciprocal engagement means. A rotational movement of the actuator arm thus causes a rotational movement of the shaft. A flapper affixed to the shaft can direct air depending on the radial position of the shaft.
