Abstract
In a throttle body for reducing the fluid pressure, particularly at a control valve, preferably for arranging in a process fluid line, of a process plant, such as a chemical plant, particularly a petrochemical plant, a power plant, a brewery or the like, with a plurality of channels extending from an upstream channel inlet to a downstream channel outlet, it is foreseen that an at least section-wise curved course of at least one of the plurality of channels between the channel inlet and the channel outlet deviates from a two-dimensional extension.
Claims15
A throttle body for reducing the fluid pressure in a process fluid line, the throttle body being in a shape of a valve cage or a throttle piston, the throttle body comprising:
- an upstream channel inlet and a downstream channel outlet;
- and
- a plurality of channels extending from the upstream channel inlet to the downstream channel outlet, wherein:
- a curved course section of at least one of the plurality of channels deviates from a two-dimensional extension between the upstream channel inlet and the downstream channel outlet, the curved course section being continuous and free of inner contour springs, steps, or kinks,
- the curved course section of the at least one of the plurality of channels is, at least at the channel inlet, three-dimensionally spiral-shaped with an increasing or decreasing curvature,
- the curved course section of the at least one of the plurality of channels is, at least at the channel outlet, three-dimensionally spiral-shaped with a decreasing or an increasing curvature, and
- in a middle section of the curved course section, the curved course section includes at least one complete helical winding with a constant curvature.
A throttle body for reducing the fluid pressure in a process fluid line, the throttle body comprising:
- an upstream channel inlet and a downstream channel outlet;
- and
- a plurality of channels extending from the upstream channel inlet to the downstream channel outlet, the at least one of the plurality of channels being configured to divide into at least two channel limbs, a curved course section of one or more of the at least two channel limbs, between a channel fork and a second channel fork, a channel outlet or a channel inlet, deviating from a two-dimensional extension,
- wherein the curved course section of at least one of the plurality of channels deviates from a two-dimensional extension between the upstream channel inlet and the downstream channel outlet.
