Abstract

PURPOSE: To equalize the input signal ratio of an actuator and the flow rate ratio of a fluid by constituting a throttle valve by a disc-shaped valve body and a valve seat having an approximately conical inner wall, and forming the valve seat wall surface into a special shape.
CONSTITUTION: The throttle valve comprises a disc-shaped valve body 4 and a valve seat 6. The valve seat wall surface is formed into a shape determined by X-Y coordinates which satisfy the right equation. Thereby, the input signal ratio of an actuator and the flow rate ratio of a fluid can be equalized. In the equation; x is the distance from the point on the valve seat wall surface at the nearest position from the valve body lower end edge to the valve seat central axis, y is the vertical distance from the point on the valve seat wall surface at the nearest position from the valve body lower end edge to the valve body closing position, r is the radius of the valve body, H is stroke, Q is flow rate, g is acceleration of gravity, ε is Q/Qmax, γ is the specific weight of the fluid, fG is the function of the fluid flow rate Q, ΔPV is pressure loss and P2S is the supply pressure of the fluid.
