    摘要: Disclosed is a control valve (10). The control valve comprises a valve body (1) and a flow pre-setting assembly (8). The flow pre-setting assembly (8) comprises an adjusting rod (81), a control component (83) and an adjusting component (82), and the control component (83) is arranged on the bottom side of the valve body (1) in a manner of being capable of rotating around an axis and is connected, in a shape-matching manner, to an end of the adjusting rod (81) which extends out of the valve body (1), so as to drive the adjusting rod (81) to rotate; the adjusting component (82) is arranged in an inner cavity and fixedly connected to the adjusting rod (81), and the adjusting component (82) can be driven by the adjusting rod (81) to rotate between a first position and a second position, so as to set the maximum opening degree of the control valve (10). The control component (83) is provided with an indication part (831) on a surface facing the valve body (1) and/or on a surface facing away from the valve body (1), the deviation of the indication part relative to a reference position can indicate the maximum flow corresponding to the position of the adjusting component (82), the reference position is fixed relative to the valve body (1), the control valve is convenient for an operator to observe and realize flow pre-setting, and the above operation can be completed without disassembling and reassembling an actuator connected to the top of the valve body.

    摘要: A fluid flow control system in which a vortex valve is combined in series with a non-fluidic control valve. The non-fluidic control valve is upstream of the vortex valve and is so arranged that small changes in its state control the operation of the vortex valve, which provides the major control over the flow of the fluid. Erosion in the non-fluidic valve due to abrasion or cavitation in the non-fluidic valve is thereby reduced.

    摘要: A gas flow control valve wherein radially disposed vanes (35, 36, 37) are mounted within an annular flange (11) with rotationally mounted shims (25, 26, 27) connecting the radial vanes to the inner peripheral surface (19) of a flange. The shims are disposed in a rim-to-rim configuration with a groove (76) defined in rims of the shims and a cable (86) laid in the grooves in a serpentine pattern. By causing one of the shims (26) to rotate by means of a sealed shaft (59) extending through the flange, the remaining shims may be driven by the cable causing corresponding motion of thevanes. The shims are mounted to the flange by means of pins (74). The shims are relatively thin such that they may be hidden beneath overhanging regions (16, 18) on opposite side walls of the flange, exposing only the radially disposed vanes to a gas flow path. Fine and coarse control modes are achieved by allowing one of the vanes (117) to be controlled by a shaft (107) through the flange independent of all shims for fine mode control and another shaft (101) driving the shims for control of the remaining vanes for coarse mode control.
