[Claims for Utility Model Registration] 1. A flow path that communicates an inlet port and an outlet port with each other, and a slide plate that is movably interposed in this flow path along the transverse axis of the flow path to open and close the flow path. a communication hole that is penetrated and formed in the slide plate along the axial direction of the flow path and overlaps a cross section of the flow path to open the flow path; a drive means for the slide plate; A pair of seat sections disposed in the flow channel along the circumferential direction of the flow channel, and the slide plate slidably interposed between the pair of seat sections are compressed by the seat sections. and urging means for urging the seat portion toward the slide plate so that the seat portion is moved toward the slide plate. 2. The seat portions are each formed in a ring shape, the biasing means are each formed of a ring-shaped member made of an elastic body, and the seat portions and the biasing means are respectively disposed on the outer end surface side of the seat portion. A biasing means is disposed coaxially in each of the flow paths, and the pressing force of each of the sheet parts against each sliding surface of the slide plate is made uniform over the entire surface of each sliding surface. The control valve according to claim 1. 3. A claim characterized in that the amount of movement of the slide plate by the driving means is adjustable, and the overlapping area of the cross sections of the communication hole and the flow path can be changed by adjusting the amount of movement. Item 1 or 2. The control valve according to item 2. 4 The driving means is formed by a first piston that is housed in a cylinder chamber so as to be movable along the axial direction and is linked to the slide plate, and the cylinder chamber has a first piston that is A second piston is housed oppositely so as to be movable along the axial direction, and a stroke end of the second piston on the first piston side is adjustable by an operating means, and the stroke end of the second piston is adjustable by an operating means. The stroke end of the first piston on the second piston side is regulated by the second piston whose end is regulated, so that the amount of movement of the slide plate can be adjusted. The control valve according to claim 3.
