Flow Control System and Method for Controlling the Flow of Liquid

A flow control system and a method for controlling the flow of liquid (6) into a tubular member (10) and from the tubular member (10), wherein the tubular member (10) comprises a perforated portion that is configured to distribute a flow of liquid (6) having a predefined fixed liquid pressure (Pw) through the perforated portion and hereby pressurise an intestine (8) that is suspended on the tubular member (10) is disclosed. The flow control system (2) comprises a flow regulating valve (4) comprising: - a slidably arranged valve structure (62) arranged in a pressurised liquid filled water chamber (70); - an elastic water-side diaphragm (54) arranged in the water chamber (70) and connected to the valve structure (62) in such a manner that the water-side diaphragm (54) allows the valve structure (62) to: a) be moved in a first direction along the longitudinal axis of the valve structure (62) and hereby increase the volume in the water chamber (70) and b) be moved in the opposite direction along the longitudinal axis of the valve structure (62) and hereby decrease the volume in the water chamber (70). The flow control system (2) comprises a force generating unit arranged and configured to provide a predefined force (Fair) to move the slidably arranged valve structure (62) in a predefined direction, wherein the force generating unit is configured to control the flow of liquid (6) in such a manner that the pressure of liquid (6) in the tubular member (10) is maintained within a predefined pressure range (PW1-PW2).
