Abstract:
The present invention is provided with: a main body (1) in which a first flow path (2) and a second flow path (3) are connected; a valve chamber (14) which is formed inside the main body (1), and which communicates with the first flow path (2); a valve seat (10) which is formed in the valve chamber (14), and which is provided with an opening that communicates with the second flow path (3); and a valve body (4) which is provided facing the opening of the valve seat (10) so as to be capable of advancing and retracting, and which adjusts the opening amount of the opening. The valve chamber (14), the valve body (4), the valve seat (10), and the second flow path (3) are coaxially provided, and disposed such that the direction from the second flow path (3) to the valve chamber (14) is vertically upward. In the main body (1), a plurality of main-body flow paths (13) communicating the second flow path (3) and the opening of the valve seat (10) are formed such that the flow directions in the plurality of main-body flow paths (13) form angles with the axial direction of the valve body (4).
