Reguleringsindsats til anbringelse i ventiler og ventilenhed

摘要

A regulating insert for mounting in valves includes a dynamically flow regulating body, with the body having a first housing that is disposed within a second housing. A coil spring is arranged about an axis thereof, and a first end of the coil spring engages a slidable bottom cup provided with at least one inlet opening for liquid in its wall. The opening has an adjustable flow area. The second end of the coil spring opposite the first end engages a partly closed end of the second housing. The partly closed end has a cylindrical opening that provides a seat for a valve cone situated within the second housing. The position of the valve cone is regulated by first means via an activation means.
