A flow rate regulation valve comprising a housing (11) formed with a valve hole (13), a needle valve (60) moved relative to the valve seat (16) in the housing, and a flow rate adjust knob (40) mounted at the proximal end of the needle valve extending from the housing, wherein the needle valve is moved relative to the valve seat by rotating the flow rate adjust knob thereby regulating the flow rate of fluid flowing through the valve hole, the flow rate regulation valve further comprising a knob fixing means (35) for stopping the rotation of the flow rate adjust knob. As a result, the flow rate is prevented from being changed accidentally by a user or the like. Further, the value may have a seal adjust means (20) adjusting the sealed state between the housing and the needle valve. The seal adjust means may be formed as a part of the housing, and may be fixed to the housing by a fixing pin (15). |
