CONTROL VALVE

摘要

A control valve having a closing element, mounted in a housing between an inlet side and an outlet side and rotatable about an axis between a first and second end positions, and a passage channel through the closing element perpendicularly with respect to the rotational axis. The channel has inlet and outlet openings and connects the inlet side to the outlet side in the first end position, disconnects the inlet side from the outlet side in the second end position, and permits an increasing throughflow of a medium during the transition from the second end position into the first end position with a characteristic curve. Low valve noise is achieved because of the shape, size and configuration of the inlet and outlet openings of the passage channel and the configuration of walls of the passage channel without steps and edges.

1. A control valve with a closing element that is pivot-mounted in a housing between an inlet side and an outlet side so as to rotate about an axis of rotation back and forth between a first end position and a second end position and has a passage channel with an inlet opening and an outlet opening running perpendicular to the axis of rotation through the closing element, and that fluidically connects the inlet side to the outlet side in the first end position and fluidically separates the inlet side from the outlet side in the second end position and, during the transition from the second end position to the first end position, allows increasing throughput of a medium with a characteristic curve, characterized in that the characteristic curve is determined by the shape and size of the outlet opening of the passage channel, that the inlet opening is embodied such that, on the inlet side, the free cross section for the medium flowing into the passage channel is dependent on the position of the closing element between the two end positions, and that the walls of the passage channel between the inlet opening and the outlet opening of the passage channel are embodied so as to be free of steps and edges.
