Document Type and Number:
Japanese Patent JP2016050646
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a flow rate adjustment valve enabling linear control with a simple mechanism, regardless of a flow rate or pressure difference.SOLUTION: A representative constitution of a flow rate adjustment valve 100 includes a plurality of blocks 110 arrayed in a closely contact manner in a flow direction in a pipeline 10, and a rotary mechanism relatively rotating the blocks around the shaft of the pipeline. The block is formed into a cylindrical shape of closing the pipeline, and in each block, a circulation 114 port is provided. By relatively rotating the blocks with the rotary mechanism, the area and flow passage wavelength of an opening in which the circulation ports communicate with each other are changed.SELECTED DRAWING: Figure 1
