Abstract
PURPOSE: To reduce resistance to steam flow by providing a plate strainer with many small holes and futher another strainer plate with holes, each of which is taper-shaped with diameter larger on the steam exit side.
CONSTITUTION: Strainer proper 3, fitted with coarse holes c for steam passage, is provided in the main steam stop valve. On the outer side of this strainer proper 3 is provided strainer 2, fitter with many small holes b for steam passage. Further, a metal net is provided on top of it. In this case, each small hole b is shaped straight up to about 1/3 of the plate thickness from the steam entrance side and the remaining part is tapered with larger diameter on the steam exit side. By this, the resistance to the steam flow is reduced and thereby pressure loss is minimized.
