This invention discloses a deluge valve with an intelligent protection device, relating to the field of deluge valve technology. It includes a valve body, a protrusion, a valve cover mounting portion, a valve cover, a sealing diaphragm, a positioning portion, a mounting base, an elastic drive mechanism, a pressure block, rotating plates, and a compression drive mechanism. The compression drive mechanism drives two rotating plates to flip downwards, causing the lower ends of the rotating plates to respectively compress the surfaces of the sealing diaphragm corresponding to the axial sides of the valve body. By setting the compression drive mechanism, the rotating plates flip downwards, and the lower ends of the two rotating plates respectively compress the sides of the protrusion. Combined with the compression of the sealing diaphragm by the pressure block, when the sealing diaphragm wears down, the rotating plates can compress the sealing diaphragm, reducing or even eliminating the gap between the sealing diaphragm and the protrusion. This prevents water leakage inside the valve body after the sealing diaphragm wears down, and also reduces the impact of fluid on the worn areas of the sealing diaphragm, thereby reducing the degree of wear on the sealing diaphragm.
