DAMPING DEVICE OF DRAIN SAFETY VALVE

摘要

FIELD: machine building.SUBSTANCE: damping device of drain safety valve (2) includes a spring suspension, guide stock (5) and assembly of guides of the valves - a cylinder on the housing and shank of the poppet. On guide stock (5) there installed is additional friction element (1) made in the form of three-insert cylindrical sleeve (3) from non-metallic material, for example from textolite that is pressed to stock (5) with pull rings (6) with specified constant force.EFFECT: providing vibration damping of a valve and damping action; reduction of full elimination of vibrational movements of the valve.3 cl, 1 dwg
