摘要

Submerged gate valve for the exhaust pipes of vehicles equipped with combustión engines, which allows the vehicle to be immersed in water with its exhaust pipe below the free surface thereof (both with the engine running and stopped), preventing the penetration of water by means of an automatic opening or closing system of the valve gate, which can be adjusted through a spring spring and depending on the pressure difference between the exhaust gas and the outside medium. The valve is characterized by the fact that the opening or closing position of the valve gate is achieved by means of an adjustment cylinder (12), connected to the gate (2) through a regulation device (9), and that a spring element (10) is provided between the adjusting cylinder (12) and the immersion gate (2) which, in the closed position of the valve, forms with the gate (2) a retention valve.
