The hydraulic filter and gates will be used in pumping pipelines, for mechanical water treatment, with pressure regulation, with prevention of leakages during failures and as small and very large gates, with protection against floods, and as air vent valves and water hammer arresters. Option one - a hydro-automatic filter complete with a composite piston (2), to a middle cone (6), bolt (7), a gap (8) is fixed, closing cylinder (9), moving around an immobile piston (10), a cylindrical grid (18) with a disk filter (19) is fixed to an upper part (3), fixed up to a cylindrical shutter (20). Option two - pressure regulator, complete with hard connected composite piston (2), with a widened rib (29), holding a control device (30), with a cylindrical aperture (32), in Which move a bolt (37) with a tight cylinder (38) and an arc welded grid fixed down (39), and a small cone (40), the large pressure regulators (43) are controlled by small pressure regulators (27). Option three - a vertical gate, complete with a widened piston (47), with the same control device (30), together with a middle vertical gate (66) control a very large vertical gate (65) on lower water level (59) and upper water level (60). Option four - an air vent valve and a water hammer arrester, complete with a widened piston (47) in its upper part, and a cylinder in its lower part (73) heavier than water, carrying a metal disk (72), fixed to screw (74) with a small cone (40) under a cone bed (33) with an aperture (75). |
