Description

Technical Field

[0001] This utility model relates to the field of explosion-proof wave valve technology, specifically an assembled explosion-proof wave valve. Background Technology

[0002] "Explosion-proof valves" are protective ventilation devices used in civil defense projects. Their main function is to ensure the safety and uninterrupted operation of the ventilation system inside the project when subjected to air raids or explosive impacts. Explosion-proof valves are protective devices installed at the air inlet and outlet of the project, capable of quickly and automatically closing under the overpressure of a shock wave and automatically resetting after the shock wave has passed. They are mainly used in civil defense projects, military facilities, industrial plants, commercial districts, transportation hubs, and other places requiring protection to resist enemy bomb attacks or accidental explosions. The installation process of traditional explosion-proof valves is relatively complex, usually requiring a large amount of on-site welding and cutting work. This not only increases the difficulty and time of construction but also easily leads to unstable installation quality due to construction errors. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3This utility model provides a technical solution: a prefabricated explosion-proof valve, comprising: a door frame 1; mounting openings 2 symmetrically opened inside the door frame 1, a mounting frame 3 installed on the inner side of the mounting openings 2, and a wave-damping valve body 4 installed inside the mounting frame 3 via hinges; positioning side plates 8 symmetrically fixedly connected to the outer side of the mounting frame 3, positioning grooves 9 symmetrically opened on the inner side of the mounting openings 2 to cooperate with the positioning side plates 8, four positioning side blocks 5 symmetrically fixedly connected to the outer side of the mounting frame 3, positioning side grooves 6 symmetrically opened on the inner side of the mounting openings 2 to cooperate with the positioning side blocks 5, the positioning side plates 8 symmetrically positioned on the outer side of the mounting frame 3 and the positioning grooves 9 are positioned and cooperated with each other, and the positioning side blocks 5 set at the four corners of the mounting frame 3 are positioned and cooperated with the positioning side grooves 6, so that the mounting frame 3 is stably installed inside the mounting openings 2.

[0020] The mounting frame 3 is fixedly connected to both sides of the mounting side plate 13. The mounting port 2 is symmetrically provided with mounting side grooves 12 that cooperate with the mounting side plate 13. The mounting side plates 13 on both sides of the mounting frame 3 cooperate with the mounting side grooves 12 symmetrically provided on the inner side of the mounting port 2 for positioning, which facilitates the positioning and installation of the mounting frame 3.

[0021] The mounting side plate 13 and the mounting side groove 12 are installed by bolts. The mounting side plate 13 is stably installed inside the mounting side groove 12 by bolts, so that the mounting frame 3 can be stably installed inside the mounting opening 2.

The positioning side block 5 is installed and fixed inside the positioning side groove 6 by the hexagon socket head cap screws 7, and the mounting frame 3 is installed and fixed inside the mounting opening 2.

[0023] The inner side of the mounting port 2 is fixedly connected to an inner limiting frame 14 that cooperates with the mounting frame 3.

[0025] Specifically, during use, the mounting frame 3 is installed inside the mounting opening 2. Positioning is achieved through the cooperation between the top and bottom positioning side plates 8 and the positioning groove 9 of the mounting frame 3. The positioning side plate 8 enters the positioning groove 9. The fixed positioning block 11 cooperates with the limiting groove 10 on one side of the positioning side plate 8, stably installing the positioning side plate 8 inside the positioning groove 9. The positioning side block 5 at the corner of the mounting frame 3 is positioned and cooperates with the positioning side groove 6. The mounting side plate 13 enters the mounting side groove 12. The installation position of the mounting frame 3 is restricted by the inner limiting frame 14 inside the mounting opening 2, limiting the installation of the mounting frame 3 inside the mounting opening 2. Multiple hexagonal socket head cap screws 7 are used to install and fix the positioning side block 5 and the positioning side groove 6. Multiple bolts are used to install and fix the mounting side groove 12 inside the mounting side plate 13, fixing the installation position of the mounting frame 3 inside the mounting opening 2, facilitating the use of the mounting frame 3 and the wave-damping valve body 4.
