<p>PROBLEM TO BE SOLVED: To provide an opening/closing valve which can reduce pressure loss.SOLUTION: A valve casing 4 which houses a valve body 8 slide-moving to a closed position and an open position is provided with an inlet part 9 and an outlet part 10 in the state that respective central axis centers X, Y are parallel and displaced in a slide direction of the valve body 8 and in the state that they are distributed to both sides of the valve body 8. The valve casing 4 is provided with an inclined flow path R linearly connecting the inlet part 9 and the outlet part 10 in an inclined posture in the slide direction of the valve body 8. The valve body 8 is configured to slide in the state that it evacuates sideways of the inclined flow path R at the open position and plunges inside the inclined flow path at the closed position to close the inclined flow path R. A flow path facing part 8A facing the inclined flow path of the valve body 8 at the open position is formed into an inclined surface shape going along a flow path inner surface of the inclined flow path R.</p> |
