Embodiment Construction

[0043] FIG. 1 shows a valve cone according to the invention for use in a valve. The valve cone comprises a cylinder 1, preferably a cylinder, which extends along a longitudinal axis A. As shown in FIG. The cylinder 1 is preferably made of metal and its cylindrical surface 5 has 4 axial grooves. The grooves are distributed evenly and equiangularly around the circumference. An outer convex line 4 extending around each groove 3 constitutes a boundary between the corresponding groove 3 and the cylinder 5 . The groove 3 extends between a first end position 14 at the first upper end 10 of the column 1 and a second end position 14 at the first end 14 of the column. Between the end 10 and the opposite second end 11 of the cylinder. In a section perpendicular to the longitudinal axis A, the groove 3 has a radial depth d and a width b, and its cross-section decreases from a maximum near the first end 10 towards the second end 14 .

Abstract

A valve cone comprises a cylindrical body extending along a longitudinal axis. The body has a cylindrical surface with at least one, axially extending recess. The recess extends inside a contour line between a first end position at a first end of the cylindrical body and a second end position, which is located between the first end of the body and the opposite second end of the body. The cross-sectional area of the recess, in a plane perpendicular to its longitudinal axis, gradually decreases from a maximum value close to the said first end towards the second end position. A valve cone of the type described above is arranged in a valve. In a method for manufacturing the valve cone, the radial recesses are formed by cutting in a single axial-radial cutting motion.

Description

technical field [0001] The present invention relates to a valve cone, a valve and a method of making the valve cone. Background technique [0002] In the various valve types of cone valves, the flow is controlled by the cooperation of the valve cone and the valve seat. Such a valve cone can be designed in various ways. [0003] DE-1062507 discloses a valve cone whose first end is connected to the valve stem and whose second end is arranged to cooperate with the valve seat. When the valve is closed, the cone is pressed against the valve seat by the valve stem and seals (pressure seal). [0004] The cone forms an axially extending radially through V-shaped groove. The cone opens and closes axially and is controlled radially by the stem. [0005] With this valve design, good controllability can only be achieved within a very narrow range. In addition, the cone causes large flow changes near the closed position, so the controllability is not good for small flows. [0006] ...
