Absperrkörpers

Absperrkoerpers, a German term, translates to "barrier bodies" or "shut-off bodies" in English. This term is primarily used in the context of engineering, particularly in fluid mechanics and valve design. It refers to the component within a valve that is responsible for controlling or stopping the flow of a fluid. This movable part is actuated by the valve stem and, when positioned correctly, it physically obstructs the passage of the fluid.

The specific design of an Absperrkoerper can vary greatly depending on the type of valve. Common forms include discs, plugs, balls, or gates. For instance, in a gate valve, the Absperrkoerper is a flat or wedge-shaped gate that slides across the flow path. In a ball valve, it is a spherical component with a bore through it that rotates to align or misalign with the pipe. In a globe valve, a disc-shaped element is pressed against a seat to achieve closure.

The material and shape of the Absperrkoerper are crucial for its function and the valve's performance. They must be durable enough to withstand the pressure and temperature of the fluid, and their design dictates the valve's sealing capability and flow characteristics. The precise movement and seating of the Absperrkoerper are essential for effective isolation or regulation of fluid flow.
