Abstract

PURPOSE: To prevent or alleviate cavitation so as to prevent or suppress the generation of noise errosion due to perishment of cavitation by giving a predetermined valve aperture curve to a valve cylinder for adjusting the valve aperture.
CONSTITUTION: A valve cylinder 3, which has a hollow cylindrical form closed at one end, is secured at the closed end to the inner end of a valve stem 2 provided for displacement within a valve casing 1. At the end of the valve cylinder 2 connected to the stem, a flange 5 co-operating with a valve seat 4 provided within a valve casing 1. The peripheral wall of the valve cylinder 3 is provided with a number of small holes 6. With the provision of the valve cylinder with a number of small holes, it is possible to realize a state close to the laminar flow within a practical range, although it may not be a perfect laminar flow, so that is is possible to prevent the phenomenon of cavitation or suppress to an extent that it practically poses no problem.
