Abstract
PURPOSE: To substantially increase the boundary effective head which is possible to be used by setting the curvature radius of the inlet enlarging neck part inner surface of the upstream side body 0.035DW0.5D to D of the valve inlet diameter, and also, by setting the deflecting angle at the needle 30°W50°.
CONSTITUTION: The hollow jet valve is equipped with an upstream body which is constituted of the cylindrical inlet part 1 and the conical enlarging part 2 and the inlet enlarging neck part 3 which connect said parts. Also equipped are the cylindrical downstream body 5 which is connected to said enlarging part 2 and the umbrella-shaped needle 7 which is equipped with the plunger which can shift in the axial direction on the same axis with said body 5. In this case, the radius of curvature R of the inlet enlarging neck part 3 inner surface to D of diameter of the valve inlet is set to be 0.35DW0.5D, and the deflecting angle θ of the needle 7 is set to be 30°W50°. By this constitution, coefficient of flow rate can be increased without a fear for generation of cavitation under high head.
