するちよう形弁。 In the case where a chimney-shaped valve is used as a restrictor for regulating the flow rate of piping, the downstream pipe of the valve is made larger than the valve diameter and expands rapidly, and the flow surface of the valve casing is expanded downstream in correspondence with the opening downstream from the center of the valve. A chimney-shaped valve characterized in that it is provided with a flow guide that extends to the side to prevent cavitation erosion of a downstream pipe.
