Description

Technical Field

[0001] The utility model relates to an explosion-proof vent valve, in particular to an explosion-proof vent valve with a detachable metal cover plate. Background Art

[0002] At present, the centralized monitoring system, battery management system, and thermal management system of new energy storage equipment are widely used in power smoothing, peak shaving and valley filling, stable new energy access, and improved renewable energy power generation efficiency. In order to ensure the safe and stable operation of energy storage equipment, each energy storage equipment needs to be equipped with an explosion-proof vent valve.

[0003] The function of explosion-proof breathable valve is waterproof and breathable. Adjust the air pressure inside and outside the equipment: when the pressure inside the cavity is greater than the pressure outside the cavity, the gas will be discharged outward, and when the pressure inside the cavity is less than the pressure outside the cavity, the gas will enter the inner cavity, thereby achieving internal and external pressure balance. Prevent explosion: when the pressure inside the cavity is greater than or equal to the explosion value set by the explosion-proof valve, it is in the explosion-proof working state. At this time, the internal pressure pushes open the breathable membrane, and the gas will pass through the barrier-free channel to the outside, realizing rapid gas discharge, thereby quickly reducing the pressure inside the cavity to prevent the explosion inside the cavity.

[0004] The function of the metal cover on the explosion-proof vent valve is to prevent large particles from entering the valve body and affecting the ventilation and explosion-proof performance; the metal cover on the existing explosion-proof vent valve is mostly fixed to the explosion-proof valve body by hot melting. Since the hot melting method will add a manufacturing process, it will increase the storage, circulation and hot melting time of materials. This will increase the overall manufacturing cost.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] like Figure 1-7 As shown, an explosion-proof vent valve with a detachable metal cover includes: Figure 1 The metal cover plate 1 shown and Figure 2 The breathable valve body 2 is shown.

[0024] The metal cover plate 1 is a square flat plate structure, and each of the four end surfaces of the metal cover plate 1 is provided with a vertical downward connecting plate 3, which is used to prevent the metal cover plate and the air-permeable valve body from being assembled. The two end surfaces of one of the connecting plates 3 are processed with a stepped guide notch 4. Figure 3 As shown, two guide protrusions 5 are provided on the air-permeable valve body 2 at positions corresponding to the two step-shaped guide notches 4. When the two step-shaped guide notches 4 are installed correspondingly with the two guide protrusions 5, the metal cover plate 1 can be installed in place with the air-permeable valve body 2. When the metal cover plate is rotated 180 degrees, it cannot be assembled with the air-permeable valve body due to interference, which can effectively avoid reverse installation.

[0025] like Figure 4 As shown, the main body of the vent valve is designed with positioning structures in both the length and width directions. The function is to control the positioning between the metal cover plate and the main body of the vent valve in the length and width directions. After the metal cover plate and the main body of the vent valve are assembled, there will be no displacement or shaking in the length and width directions.

[0026] Specifically, the front, rear, left and right ends of the lower surface of the metal cover plate 1 are all provided with positioning grooves 6, and the vent valve body 2 is provided with six positioning protrusions 7 at positions corresponding to the six positioning grooves 6. Figure 5 , 6 As shown, when the six positioning protrusions 7 on the air-permeable valve body 2 are embedded in the six positioning grooves 6 on the metal cover plate 1 in a one-to-one correspondence, the metal cover plate 1 can be restricted from moving forward, backward, left, and right.

[0027] like Figure 7 As shown, the four connecting plates 3 are each provided with a card slot 8, and the ventilation valve body 2 is provided with a plurality of hooks 9 at positions corresponding to the plurality of card slots 8. When the plurality of hooks 9 on the ventilation valve body 2 are connected to the plurality of card slots 8 on the metal cover plate 1 one by one, the metal cover plate 1 can be restricted from moving up and down.

[0028] A threaded hole 10 is respectively provided at the four corners of the air valve body 2, and a screw through hole 11 is also provided on the metal cover plate 1 corresponding to the threaded hole 10. The metal cover plate 1 is locked and fixed to the air valve body 2 by screws passing through the screw through holes 11 and the threaded holes 10.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
