COVER STRUCTURE DEVELOPED FOR SILO DISCHARGE VALVES

摘要

The invention is related to cover structure that prevents adhesion of undesirable substances such as dust, mud and waste water to valve flap (3), which by means of an actuator (4) enables opening/closing of discharge valve (2) in silo vehicles carrying powdered and granular materials on highways, and thus prevents contamination of such substances to the materials in the tank. The invention contains a protective cover (8) that is located under the discharge valve (2); a drive transmitter (5) that transmits the required driving power by turning of the actuator (4) that it is engaged, for synchronous operation of the mentioned protective cover (8) and the discharge valve (2); a jointed interconnecting piece (9) that transmits the movement from the mentioned drive transmitter (5) to the protective cover (8) that it is engaged; a guide plate (6) that guides horizontal opening and closing of the mentioned protective cover (8) on its route (6.1), and that is assembled with the mentioned discharge valve (2); and a flange (7) that ensures the connection of the protective cover (8) and the mentioned guide plate (2).
