摘要： A multistage throttle valve has a generally cylindrical housing with an inlet adjacent one end and an outlet at the other end. The interior of the housing is spanned by several, axially spaced valve seat plates having coaxial apertures therethrough of progressively larger sizes toward the outlet. An axially movable operating rod passes axially through the apertures and carries at least one of several valve discs thereon. An operating tube is disposed around the operating rod and carries the valve discs not carried by the rod. The tube is movable axially along the rod and can be fastened thereto.
