Embodiment 1

[0040] Embodiment 1. The present invention provides a waterproof body pressure relief valve, such as figure 1 As shown, it includes a frame 1 and a plurality of blades 2 rotatably connected to the frame 1 . The framework 1 includes a bracket 11 and a first side wall 12 and a second side wall 13 fixedly connected to the bracket 11 near both ends of the blade 2, and a side wall fixedly connected to the bracket 11, the first side wall 12 and the second side wall 13. The top wall 14 and the bottom wall 15 , the blade 2 is rotatably connected to the bracket 11 , the blade 2 is arranged along the width direction of the framework 1 , and the top wall 14 and the bottom wall 15 are respectively located at two ends of the bracket 11 in the length direction. All blades 2 can jointly cover the cross-section of the skeleton 1 . When the pressure relief valve starts to release the pressure, the vane 2 rotates, so that the frame 1 has a gap allowing the gas to pass through, and the pressure...

Embodiment 2

[0049] Embodiment 2, a waterproof body pressure relief valve, differs from Embodiment 1 in that the inclination angle between the first side wall 12 and the second side wall 13 is α, and the angle α in this embodiment is 10°. The widths of the top wall 14 , the first side wall 12 , the bottom wall 15 and the second side wall 13 are all β, and the width β in this embodiment is 23 mm.

Embodiment 3

[0050] Embodiment 3, a waterproof body pressure relief valve, differs from Embodiment 1 in that the inclination angle of the first side wall 12 and the second side wall 13 is α, and the angle α in this embodiment is 6°.

Abstract

The invention relates to the technical field of vehicle bodies, in particular to a waterproof vehicle body pressure release valve. The waterproof vehicle body pressure release valve comprises a framework and a plurality of blades rotationally connected to the framework, a waterproof outer frame is connected to one side of the framework, a plurality of waterproof baffles are rotationally connected into the waterproof outer frame, and the waterproof baffles are arranged in the width direction of the waterproof outer frame. The waterproof baffles are fixedly connected with rotating shafts, the rotating shafts are arranged in the width direction of the waterproof outer frame, the rotating shafts are rotationally connected to the waterproof outer frame, and all the waterproof baffles can jointly cover the cross section of the waterproof outer frame. The pressure release valve has the advantage that water flow is prevented from entering a vehicle body through the pressure release valve on the premise that normal pressure release of the pressure release valve is not affected.

Description

technical field [0001] The invention relates to the technical field of vehicle bodies, in particular to a waterproof pressure relief valve for vehicle bodies. Background technique [0002] At present, the pressure relief valve refers to a device that can automatically open and close according to the working pressure of the system, and is generally installed on the equipment or pipeline of the closed system to protect the safety of the system. The automobile pressure relief valve is mainly used for pressure relief. The function of the automobile pressure relief valve is to control the pressure in the intake pipe below the limit value. pressure range. [0003] There is a utility model patent with an application publication number of CN208149010U, which protects a silent air pressure relief valve for automobiles, including a frame-shaped housing. The interior of the frame-shaped housing is stepped and arranged side by side with several slopes, each Ventilation openings are ar...
