The diaphragm is arranged in a sealed space formed by the protective cover and the base in the inner part, and is attached to the upper surface of the base, and when the internal pressure reaches a limit value, the diaphragm is damaged to achieve a continuous pressure relief function. Wherein, the position of laminating the diaphragm on the base is the base through-flow face.
The O-shaped sealing ring is arranged on the lower surface of the base, namely the mounting surface of the explosion-proof pressure relief device, and rainwater erosion on the mounting surface is prevented.
The periphery of the base flow surface is provided with notches so as to discharge rain and fog condensed water drops and ensure that no accumulated water exists at the diaphragm and the joint.
Furthermore, the diaphragm is attached to the base through-flow surface in a gum mode.
Furthermore, the base is further provided with through holes for fixing and mounting, and the through holes are symmetrically arranged around the base.
furthermore, the protective cover and the base are detachably connected, fixedly connected or integrally formed.
The basic working method of the invention is as follows: the diaphragm is laminated with the base through gum mode and through-flow face, and the diaphragm is damaged promptly after internal pressure reaches the limit value to reach and continue the pressure release function.
The invention has the beneficial effects that:
(1) the diaphragm is attached to the through-flow surface of the base in a gum mode, and when the internal pressure reaches a limit value, the diaphragm is damaged to achieve a continuous pressure relief function;
(2) Notches are arranged on the periphery of the flow surface of the base so as to discharge rain mist condensed water drops and ensure that no accumulated water exists at the diaphragm and the joint;
(3) the top surface of the independent protective cover can prevent rain erosion on the front surface, and the side surface can prevent rain splashing erosion;
(4) The O-shaped sealing ring can prevent rainwater erosion on the mounting surface;
(5) The explosion-proof explosion-reducing safety protection device has the advantages of simple structure, clear function, better reliability and convenient installation, and makes up the defects of explosion-proof explosion-reducing safety protection of the power battery chamber of the hybrid locomotive.
