HYDRAULIC DISTRIBUTION OF PRESSURE LIQUID ESPECIALLY FOR CONTROL OF GAS CAPTATION'S BELL CLOSURE

It enhances the simplicity of a hydraulic system by maintaining its dynamic stability, lowering its investment cost, and enhancing its reliability. The pressure liquid supply (3), through its pressure piping (4), is connected to a choke valve (5) with a by-pass, interconnected with a pressure inlet of a proportionate distributor PD (7), whose waste outlet is interconnected with a return pipe (8) to a main return pipe - MRP (9), to which the outlet of a draining valve (10) is also connected, with an inlet connected to a pressure pipe (4). The first pressure outlet of the PD (7) is interconnected, through a return valve (15), to MRP (9). The second pressure outlet of the PD (7) is, through a one-way valve (17), connected to the return pipe (16) of the return space (11) of a linear hydraulic motor (13), to which a branch pipe (21) with a safety valve (22) is connected, interconnected with MRP (9). In parallel, a differential line (18) is connected to the return pipe, connected to the inlet of the flap valve (19), which, through an outlet pipe (20), is connected to a supply line (6).
