Device for regulating the throughflow of a flowing medium, e.g. water, through a line which channels the flowing medium

摘要

The invention relates to a device for regulating the throughflow of a flowing medium through a line (3) which channels the flowing medium. It has an inflatable pneumatic element (10) which is to be arranged in the interior of the line (3). This is in connection, via a filling and ventilating line (14) which can be guided through a line opening (15), with a device (16) which is located outside the line (3) and is intended to control the filling quantity of the pneumatic element (10). In dependence on its respective filling quantity, the pneumatic element (10) closes the throughflow cross-section of the line (3) to a greater or lesser extent or closes it completely. IMAGE
