Claims

[Claims for Utility Model Registration] A water-saving valve installed in the outlet side flow path of a flow rate adjustment valve, wherein the flow rate in the outlet side flow path increases when the flow rate adjustment valve is operated in the opening direction. Therefore, in the water-saving valve for flow rate adjustment valve that reduces the flow rate on the outlet side of the water-saving valve, a fluid inlet opening provided at one end in the axial direction, a fluid outlet opening provided at the other end in the axial direction, a first inner diameter portion of an inner diameter r ¹ communicating with the fluid inlet opening and an inner diameter r ² communicating with the fluid outlet opening (r ² <r ¹ );
a second inner diameter portion of the first inner diameter portion;
a casing comprising a conical valve seat surface connecting an inner diameter portion of the casing, and an outer diameter R (r ¹ >R> ^r2 ); a stopper member attached to the fluid inlet opening side of the casing to limit axial movement of the spherical valve; the spherical valve and an inner wall surface of the bottom of the casing; 1. A water-saving valve for a flow rate adjustment valve, characterized in that the spring member is stretched between the valve body and biases the spherical valve body toward the stopper member.
