Abstract
PURPOSE: To facilitate complicated calculation in designing a throttle valve, by making the valve so formed that the throat area ration between a disk type valve body and a valve seat whose wall surface is expanded toward downstream can satisfy a specific condition.
CONSTITUTION: A throttle valve is composed of a valve seat 12 with a wall surface expanded toward downstream of controlled fluid and a disk type valve body 11 in contact with the valve seat 12. The shape of the wall surface of the valve seat 12 is so designed that the throat area between the wall surface and the said valve body can satisfy an equation shown elasewhere, where A is the throat area of valve, Amax is the valve's throat area at the valve body's maximum stroke, a is a constant and ε is a ratio between the valve body's stroke S and its maximum stroke Smax. Since the cross section of the wall surface composed of straight lines and hyperbola, its calculating is very easy in designing, which makes it easy to adjust or change the wall design.
