Title:
METHOD AND DEVICE FOR REGULATING THE FLOW OF A FLUID FROM A VESSEL UNDER NEGATIVE PRESSURE
Document Type and Number:
WIPO Patent Application WO/2022/211682
Kind Code:
A1
Abstract:
The invention relates to devices for draining fluids from vessels that are under a negative pressure relative to atmospheric pressure. A method for regulating the flow of a fluid from a vessel under negative pressure, which includes the use of a valve with a seat and the formation of a hydraulic seal above said seat, is characterized in that a movable part of the valve is acted on by a valve closure mechanism so that when a gap between said movable part of the valve and the seat increases, the valve closure mechanism increases the valve closing force. Also claimed is a regulating device. The technical result is that of improving the operational stability of a drainage system, simplifying and expediting cleaning, and increasing the service life of the device irrespective of cleaning.
