Description

Technical Field

[0001] This utility model relates to the technical field of exhaust valves, and in particular to an explosion-proof overpressure exhaust valve. Background Technology

[0002] In civil defense projects, in order to protect the exhaust vents during peacetime, to isolate and protect the civil defense project from shock waves during wartime, and to filter and ventilate the interior of the civil defense project when it is under overpressure, an explosion-proof overpressure exhaust valve is often required.

[0003] Chinese Patent Publication No. CN218440839U discloses an explosion-proof overpressure exhaust valve, comprising a housing, with a sealing assembly inside the housing. The sealing assembly includes two sliding grooves, two sliding blocks, an arc-shaped plate, several first springs, and a sealing valve. The two sliding grooves are respectively opened on both sides inside the housing, and sliding blocks are slidably connected to the inner walls of both sliding grooves. An arc-shaped plate is fixedly connected between the two sliding blocks, and several first springs are fixedly installed on the inner wall of the arc-shaped plate. The beneficial effects of this utility model are: the sealing valve moves by the air pressure difference between the inside and outside of the civil defense project; the sealing degree of the exhaust valve is controlled by the size of the gap area between the sealing valve and the arc-shaped plate, making the exhaust valve more automated; the two third springs reset and drive the clamping ring to clamp the push rod, preventing the push rod from loosening and improving the stability of the sealing valve during sealing; and several annular aluminum foam rings facilitate noise reduction of the gas flowing inside the exhaust valve.

[0004] However, in this patent, when it is placed on the wall of a civil defense project with ventilation openings for installation, the relatively smooth surface of the wall results in low friction between the device and the wall. This makes it easy for the device to slide along the wall with ventilation openings during installation, increasing the difficulty of installation. Furthermore, in this patent, the angle of the device is fixed after installation, so any adjustment to the angle requires disassembly and reinstallation, which is time-consuming and labor-intensive, further increasing the difficulty of adjusting the angle.

[0031] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates an explosion-proof overpressure exhaust valve according to this utility model.

[0032] like Figures 1 to 12 As shown: An explosion-proof overpressure exhaust valve includes an explosion-proof overpressure exhaust valve body 16, a first support ring 3, a sealing pressure ring 19, a fourth support ring 11, a third support ring 10, a connecting ring 7, and a mounting block 1. Multiple anti-slip balls 23 are fixedly connected to the rear side of the sealing pressure ring 19, and a fifth support ring 20 is fixedly connected to the front side of the sealing pressure ring 19. The fifth support ring 20 is movably connected to the explosion-proof overpressure exhaust valve body 16. A threaded shaft 8 is rotatably connected to the front side of the fifth support ring 20. A convex shaft 22 is fixedly connected to one end of the threaded shaft 8 near the fifth support ring 20, and a gripping post 9 is fixedly connected to the other end of the threaded shaft 8 away from the convex shaft 22. A second limiting ring 21 is fixedly connected to the outer surface of the end of the gripping post 9 near the threaded shaft 8. There are three gripping posts 9. The fourth support ring 11 is threadedly connected to the threaded shaft 8. A second arc-shaped long plate 6 is slidably installed inside the connecting ring 7. The front side of the plate 6 is fixedly connected to the first arc-shaped long plate 5. The interior of the mounting block 1 and the interior of the ring body of the first support ring 3 are threaded together with mounting screws 2. There are three mounting screws 2. Through the setting of the mounting components, the device can be installed on the wall of the civil defense project with ventilation openings. Through the setting of the anti-slip components, support components and first positioning components, the anti-slip components can prevent the explosion-proof overpressure exhaust valve body 16 from sliding during installation, the support components can support the anti-slip components, and the first positioning components can position the anti-slip components. When the device is placed on the wall of the civil defense project with ventilation openings for installation, the device can increase the friction between the device and the civil defense project wall, so that the device can avoid the difficulty of installation due to easy sliding along the wall of the civil defense project with ventilation openings, and the device can be installed conveniently.

[0033] In use, the device is initially positioned such that one end of the first support ring 3 is located inside the ring body of the first support ring 3 and inside the mounting block 1. Multiple anti-slip balls 23 are located within the space formed by the fourth support ring 11 and the third support ring 10. Two screws 14 are threadedly connected to two threaded grooves 17. In civil defense projects, when this device is needed, it is moved to the wall of the civil defense project with ventilation openings, so that the first support ring 3, the fourth support ring 11, and the explosion-proof overpressure exhaust valve body 16 are all in contact with the wall of the civil defense project with ventilation openings. After the first support ring 3, the fourth support ring 11, and the explosion-proof overpressure exhaust valve body 16 are all in contact with the wall of the civil defense project with ventilation openings, the three gripping columns 9 are simultaneously rotated to make the gripping columns... 9 and the second limiting ring 21 both rotate along the connecting ring 7, causing the threaded shaft 8 and the convex shaft 22 to rotate along the fifth support ring 20. Under the action of the threaded transmission, the threaded shaft 8 rotates along the fourth support ring 11 and moves towards the direction of the air-raid shelter wall with the ventilation opening, causing the connecting ring 7 to slide along the second arc-shaped long plate 6 and the explosion-proof overpressure exhaust valve body 16 towards the direction of the air-raid shelter wall with the ventilation opening, causing the fifth support ring 20 to slide along the fourth support ring 11 and the third support ring 10 towards the direction of the air-raid shelter wall with the ventilation opening, and causing the sealing pressure ring 19 to slide along the fourth support ring 11 and the third support ring 10 towards the direction of the air-raid shelter wall with the ventilation opening, causing multiple Each anti-slip ball 23 moves towards the wall of the civil defense project with ventilation openings. When the threaded shaft 8 rotates along the fourth support ring 11 and moves to its maximum distance towards the wall of the civil defense project with ventilation openings, the multiple anti-slip balls 23 are in contact with the wall of the civil defense project with ventilation openings under the state of being squeezed and deformed. Under the action of the multiple anti-slip balls 23, the friction between the device and the wall of the civil defense project with ventilation openings can be increased. After the multiple anti-slip balls 23 are in contact with the wall of the civil defense project with ventilation openings under the state of being squeezed and deformed, the three mounting screws 2 are rotated at the same time, so that the mounting screws 2 rotate along the mounting block 1 and the first support ring 3 respectively and move towards the wall of the civil defense project with ventilation openings. The device moves towards the wall. When the mounting screw 2 rotates along the mounting block 1 and the first support ring 3 respectively and moves to its maximum distance towards the wall of the civil defense project with the ventilation opening, one end of the mounting screw 2 is inserted into the interior of the civil defense project wall with the ventilation opening. At this time, the device can be installed on the civil defense project wall with the ventilation opening. During the installation process, the device increases the friction between itself and the civil defense project wall, preventing it from easily sliding along the wall with the ventilation opening, which would increase the difficulty of installation and make the installation easier. After the device is installed on the civil defense project wall with the ventilation opening...Under the action of the explosion-proof overpressure exhaust valve body 16, this device can protect the exhaust vents of civil defense projects during peacetime, isolate and protect the civil defense projects when subjected to shock waves during wartime, and filter and ventilate the interior of the civil defense projects when overpressure is maintained. This device can be used in these situations.

[0034] like Figures 1 to 12 As shown: An explosion-proof overpressure exhaust valve includes an explosion-proof overpressure exhaust valve body 16, a first support ring 3, a second support ring 4, a limiting block 15, and a connecting plate 13. A first limiting ring 18 is rotatably mounted inside the second support ring 4. Multiple threaded grooves 17 are formed on the outer surface of the first limiting ring 18. A screw 14 is threadedly connected to both the inside of the limiting block 15 and the inside of the second support ring 4. Two screws 14 are threadedly connected to the threaded grooves 17. A positioning ring 12 is fixedly connected to the rear side of the connecting plate 13. Through the arrangement of the first support ring 3, the angle adjustment component, the limiting component, and the second positioning component, the angle adjustment... The section component can adjust the angle of the explosion-proof overpressure exhaust valve body by 16 degrees after installation, allowing the limit component to limit the angle adjustment component and the second positioning component to position the angle adjustment component. After the device is installed on the wall of a civil defense project with ventilation openings, when the angle of the device needs to be adjusted, the device can directly adjust the angle after installation. This avoids the time and effort required to adjust the angle after installation by disassembling and reinstalling, and avoids increasing the difficulty of adjusting the angle after installation by time and effort. This device makes it easy to adjust the angle after installation.

[0035] In use, after installing this device onto the wall of a civil defense project with ventilation openings, when the angle of the device needs to be adjusted after installation, simultaneously rotate the three gripping columns 9 in the opposite direction. This causes the gripping columns 9 and the second limiting ring 21 to rotate in the opposite direction along the connecting ring 7, and causes the threaded shaft 8 and the convex shaft 22 to rotate in the opposite direction along the fifth support ring 20. Under the action of the threaded transmission, the threaded shaft 8 rotates in the opposite direction along the fourth support ring 11 and moves away from the civil defense project wall with ventilation openings. This causes the connecting ring 7 to slide along the second arc-shaped long plate 6 and the explosion-proof overpressure exhaust valve body 16 respectively in the direction away from the civil defense project wall with ventilation openings. This causes the fifth support ring 20 to slide along the fourth support ring 11 and... The third support ring 10 slides away from the wall of the civil defense project with the ventilation opening, causing the sealing ring 19 to slide along the fourth support ring 11 and the third support ring 10 away from the wall of the civil defense project with the ventilation opening. This causes the multiple anti-slip balls 23 to move away from the wall of the civil defense project with the ventilation opening. When the threaded shaft 8 rotates along the fourth support ring 11 and moves to its maximum distance away from the wall of the civil defense project with the ventilation opening, the multiple anti-slip balls 23 return to their shape and disengage from the wall of the civil defense project with the ventilation opening. After the multiple anti-slip balls 23 return to their shape and disengage from the wall of the civil defense project with the ventilation opening, the two screws 14 are rotated simultaneously. Disconnect the two screws 14 from the two threaded grooves 17, ensuring one end of each screw 14 is inside the second support ring 4. Rotate the explosion-proof overpressure exhaust valve body 16, causing both the explosion-proof overpressure exhaust valve body 16 and the third support ring 10 to rotate. This causes the fourth support ring 11 to rotate along the second support ring 4 and the first support ring 3, respectively. The first limiting ring 18, connecting plate 13, and positioning ring 12 also rotate along the second support ring 4, changing the angle of the device after installation. When the angle of the device after installation is changed to the desired angle, and when the two screws 14 correspond to the other two threaded grooves 17, simultaneously rotate the two screws 14 in the opposite direction, threading them into the other two threaded grooves 17. At this point, the device can be adjusted to the installed angle. When the device has finished adjusting the installed angle, all the anti-slip balls 23 are in contact with the air-raid shelter wall with ventilation openings under the state of being squeezed and deformed. After the device is installed on the air-raid shelter wall with ventilation openings, when the device needs to adjust the installed angle, the device can directly adjust the installed angle during the adjustment process. This avoids the time and effort required to adjust the installed angle by disassembling and reinstalling, thus avoiding the increased difficulty of adjusting the installed angle due to the time and effort required. This allows the device to be easily adjusted to the installed angle.

[0036] In this embodiment, the anti-slip ball 23 is a half-sphere and the material of the anti-slip ball 23 is rubber, and the cross-section of the positioning ring 12 is convex.
