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.

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 utility model discloses a basic working method does: 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 beneficial effects of the utility model reside in 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 utility model discloses simple structure, function are clear and definite, the reliability is better, simple to operate, and remedied the not enough of explosion-proof safety protection of hybrid vehicle power battery room.

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention, i.e., the described embodiments are only some, but not all embodiments of the invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiment of the present invention, all other embodiments obtained by the person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in figures 1-4, a locomotive is with explosion-proof pressure relief device of disposable, including O type sealing washer 1, base 2, protection casing 3 and diaphragm 4, protection casing 3 sets up in base 2 top, and positive rainwater erosion can be prevented to its top surface, and the side can be prevented that the rain water droplet spatters the erosion, and protection casing 3 is connected with base 2 detachable, fixed connection or integrated into one piece. As shown in fig. 5, the membrane 4 is disposed in the sealed space formed by the protective cover 3 and the base 2, and is attached to the upper surface of the base 2, and when the internal pressure reaches a limit value, the membrane 4 is damaged to achieve the continuous pressure relief function. The position of laminating diaphragm 4 on base 2 is base 2 through-flow face, and is specific, and diaphragm 4 laminates through gum mode and base 2 through-flow face. In addition, the periphery of the flow surface of the base 2 is provided with a notch 6 so as to discharge rain and fog condensed water drops and ensure that no accumulated water exists at the membrane 4 and the joint.
