量制御弁。[Claims for Utility Model Registration] A flow path for fluid circulation is formed in a housing for forming a valve, an inflow valve seat for fluid inflow is formed at one end of the flow path, and the other end of the flow path is formed. A first valve seat for fluid outflow is formed in the flow path, a second valve seat for fluid diversion is provided on a lower wall surface between the inflow valve seat and the first valve seat of the flow path, and a second valve seat for fluid diversion is provided in the flow path. A flow control valve having a loosely inserted ball-shaped valve body that reciprocates between the inflow valve seat and a first valve seat due to changes in fluid pressure, the inflow valve seat being located below the first valve seat. When the valve body receives a predetermined fluid pressure and seats on the second valve seat, a vertical line passing through the center of gravity of the valve body faces the inflow valve seat side on the outside of the second valve seat. Flow rate control characterized in that the first valve seat is provided with a passage that allows the passage of the fluid to pass through when the valve body is seated on the first valve seat. valve.
