VALVE FOR PRESSURIZED LIQUIDS WITH A SAFETY DEVICE FOR CLOSING THE VALVE

Abstract

Valve (10) for pressurized fluids, comprising: - a valve body part (11) having an inlet (12) and an outlet (13) for a fluid and accommodating a discharge pipe (14) which fluidically connects the inlet (12) to the outlet (13), - a shut-off device (15) accommodated in the valve body part (11) which is designed to block and selectively release the fluid passage into the discharge pipe (14), - a lever (16) which is articulated to the valve body part (11) in the region of a pivot axis (X) and is designed to actuate the shut-off device (15), - a safety device (17) for closing the valve (10), wherein the safety device is mounted on the lever (16) and is designed to be rotated together with it about the pivot axis (X), wherein the safety device (17) comprises: - a coupling element (19) which is rotatably attached to the lever (16) is mounted about a rotational axis (Z),to move from a disengaged position to an engaged position with a recess (20) formed on the wall of the valve body part (11) by snapping a respective coupling end (21) into the recess (20), to hold the lever (16) adjacent to the valve body part (11), wherein the coupling element (19) is mounted on the lever (16) such that it moves from the engaged position to the disengaged position by rotation corresponding to the opening rotation of the lever (16), an elastic return element (22) designed to force the coupling element (19) into the engaged position, a push button (23) accessible from the outside of the lever (16), the outside being opposite an inside facing the valve body part (11), the push button being operatively connected to the coupling element (19) in such a way thatthat by pressing the push button (23) on the clutch element (19) a rotation is exerted, overcoming the elastic force of the elastic return element (22), so that it is moved from the engaged position to the disengaged position.
