Title:
Valve cage with no dead zone between noise reduction and high volume flow categories
Document Type and Number:
Japanese Patent JP6352283
Kind Code:
B2
Abstract:
A valve cage for a fluid flow control device includes a hollow cylindrical body, a noise abatement section, a high capacity flow section, and a transition section. The noise abatement section has a plurality of inlet openings, a plurality of outlet openings, and a plurality of tortuous flow paths extending between the inlet and outlet openings. The high capacity flow section is disposed axially adjacent to the noise abatement section and includes a first axial end, a second axial end, and a plurality of primary flow openings. The transition section is defined at an interface between the noise abatement section and the second axial end of the high capacity flow section and includes a plurality of transition openings. The transition section provides a valve cage with zero dead band between the noise abatement and high capacity flow sections when implemented into a fluid flow control device.
