    摘要： Presented are a method, apparatus and valve assembly for preventing rotation. An exemplary valve assembly includes a butterfly valve rotatably moveable between a closed position and an open position, and a shaft extending from the butterfly valve and rotatable about a longitudinal axis to move the butterfly valve between the open position and the closed position. The valve assembly further includes an actuator having a body operable to maintain an end portion of the shaft, the actuator operable to cause the shaft to rotate about the longitudinal axis, a housing sized to retain a portion of the shaft, the housing operable to be in removeable contact with the body, a seal intermediate the body and the shaft, the seal having an outer sealing surface contacting the body and an inner sealing surface contacting the shaft, and an anti-rotation interface between the seal and the housing.

    摘要： A method of designing a valve presenting an orifice of section that depends on the position of the valve member of the valve, which section can thus be controlled. The method includes determining a desired variation relationship for the flow section of the valve, which relationship defines a desired variation in the section as a function of time; setting a predetermined movement relationship for the valve member; and defining the shape of the fluid flow orifice in such a manner that, at each instant, if the valve member moves in compliance with the predetermined movement relationship, the flow section remains equal to the desired section. The method makes it possible to design a valve that is simple to control.

    摘要： Axial fluid valves having annular flow control members are described herein. An example axial fluid valve described herein includes an axial flow valve body defining a passageway between an inlet and an outlet. The example axial fluid valve includes a sleeve slidably received by an inner surface of the axial flow valve body and movable along an axis substantially parallel to a longitudinal axis of the passageway. The example axial fluid valve includes a linkage or a gear operatively connected to the sleeve to move the sleeve to vary a flow of fluid between the inlet and the outlet through the sleeve.

    摘要： A flow control assembly for a fire sprinkler system includes a valve housing having an inlet opening and an outlet opening. The valve housing defines a fluid flow path that extends between the inlet opening and the outlet opening. A flow control valve is disposed within the fluid flow path. A swing check valve is disposed within the fluid flow path of the valve housing downstream from the flow control valve. The swing check valve includes a clapper that is connected to an actuator arm. An electrical switch is disposed outside of the valve housing. A mechanical linkage includes a first end that extends through the valve housing and engages with the actuator arm. The mechanical linkage also includes a second end that is coupled to the electrical switch. The first end translates with said actuator arm.

    摘要： A driving device for adjusting an activating element of a throttle, of a valve, of a connecting device, of a metering device or the like in particular in the field of oil and gas exploration with at least one rotary gear movably connected to the activating element and a gear arranged between the rotary gear and at least one motor. To improve such a drive device in that the structure is simple and compact and efficiency is increased wherein simultaneously high axial forces are avoided and only a small number of assembly parts are necessary, the gear unit comprises a reduction gear assigned to the rotary gear in particular the so called harmonic drive gear, and a spare gear assigned to the motor which is in particular self locking.
