Description

Technical Field

[0001] This utility model relates to the field of explosion-proof wave valves, specifically an explosion-proof wave valve with an adjustable function. Background Technology

[0002] Blast wave breaker is a type of protective ventilation equipment used in civil defense projects. Its main function is to ensure that the ventilation system inside the project is not damaged during air raids or nuclear blast shock waves, while maintaining the continuity of ventilation. Blast wave breaker is usually made of steel and can be divided into two types: swing type and hose type, depending on the material. In the instant of a nuclear blast shock wave, the breaker will automatically close, thereby protecting the ventilation equipment inside the project from damage. In addition, the blast wave breaker can automatically reset after the shock wave passes, ensuring the continuous operation of the ventilation system.

[0003] However, most of the existing explosion-proof wave valves on the market do not have adjustable swivel plates, which means they cannot be adjusted according to ventilation requirements, thus reducing the usability of the device and its practicality. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable explosion-proof wave valve. This valve allows the angle of the swivel plate to be adjusted according to ventilation requirements, thereby meeting the device's usage needs and improving its practicality. This solves the problem that the swivel plate of the explosion-proof wave valve cannot be adjusted to meet ventilation requirements, thus reducing the device's usability and practicality.

[0006] (II) Technical Solution

[0007] To achieve the goal of adjusting the angle of the swivel plate according to ventilation requirements, thereby meeting the usage needs of the device and improving its practicality, this utility model provides the following technical solution: an explosion-proof wave valve with adjustable function, comprising a wave valve body, a ventilation opening processed on one side of the wave valve body, and a swivel plate rotatably connected to the inner wall of the ventilation opening; a support frame fixedly connected to one side of the wave valve body, a rotating rod fixedly connected to the inner wall of the support frame, and a connecting column rotatably sleeved on the outer wall of the rotating rod; a first connecting plate fixedly connected to one end of the connecting column; a second connecting plate fixedly connected to one end of a first spring fixedly connected to one side of the first connecting plate; a universal joint provided at one end of the second connecting plate; one side of the universal joint fixed to one side of the swivel plate; a limit channel opened on the inner side wall of the connecting column; and an adjusting component provided inside the connecting column.

[0008] As a preferred embodiment of this utility model, the support frame has a "U" shaped structure, and the outer wall of the connecting column is rotatably connected to the inner wall of the support frame.

[0009] As a preferred embodiment of this utility model, the first connecting plate has a "ring" shaped structure, and the second connecting plate has the same shape as the first connecting plate.

[0010] As a preferred embodiment of this utility model, the adjusting component includes an adjusting rod, one end of which extends into the interior of the connecting column. The outer wall of the adjusting rod is slidably connected to the inner wall of the connecting column. A groove is provided on the outer wall of the adjusting rod, and a second spring is fixedly connected to the inner side wall of the groove. A limit block is fixedly connected to one end of the second spring.

[0011] As a preferred embodiment of this utility model, one side of the limiting block is an inclined surface, and the outer wall of the limiting block is slidably connected to the inner wall of the groove.

[0012] As a preferred embodiment of this utility model, one end of the limiting block penetrates through the limiting channel and extends to the outside of the connecting column, and the outer wall of the limiting block is slidably connected to the inner wall of the limiting channel.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an explosion-proof wave valve with adjustable function, which has the following beneficial effects:

[0015] 1. By pressing the limiting block, one end of the limiting block will move into the limiting channel. Then, one end of the adjusting rod will move into the connecting column. The inclined surface of the limiting block will be acted upon, causing the limiting block to move into the groove. This allows the adjusting rod to move into the connecting column. Since there are several limiting channels, the limiting block will engage with the corresponding channel, thus shortening the total length between the connecting column and the adjusting rod. This allows the swivel plate to rotate, changing its angle. The adjusting rod will not move into the connecting column automatically, preventing the swivel plate from automatically adjusting its angle. This allows the device to adjust the angle of the swivel plate according to ventilation requirements, thus meeting the device's usage needs and improving its practicality.

[0016] 2. When one side of the valve body is subjected to a large explosive impact, the swing plate will be impacted and rotate towards the valve body. The swing plate will then seal the ventilation opening on the valve body, thus providing an explosion-proof function. After the explosion, the first spring will drive the swing plate to reset, thereby enabling continued ventilation and improving the practicality of the device. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] Reference Figure 1-4 This is the first embodiment of the present invention, which provides an explosion-proof wave valve with an adjustable function, including a wave valve body 1. A ventilation opening is processed on one side of the wave valve body 1, and a swing plate 2 is rotatably connected to the inner wall of the ventilation opening. A support frame 3 is fixedly connected to one side of the wave valve body 1. A rotating rod 4 is fixedly connected to the inner wall of the support frame 3. A connecting column 5 is rotatably sleeved on the outer wall of the rotating rod 4. A first connecting plate 6 is fixedly connected to one end of the connecting column 5. A first spring 7 is fixedly connected to one side of the first connecting plate 6, and a second connecting plate 8 is fixedly connected to one end of the first connecting plate 6. A universal joint 9 is provided at one end of the second connecting plate 8. One side of the universal joint 9 is fixed to one side of the swing plate 2. A limit channel 10 is opened on the inner side wall of the connecting column 5, and an adjusting component is provided inside the connecting column 5.

[0025] Specifically, the support frame 3 has a "U" shaped structure, and the outer wall of the connecting column 5 is rotatably connected to the inner wall of the support frame 3. One end of the connecting column 5 can rotate inside the support frame 3.

[0026] Specifically, the first connecting plate 6 has a "ring" shaped structure, and the second connecting plate 8 has the same shape as the first connecting plate 6. The first connecting plate 6 and the second connecting plate 8 can serve as support and connection.

[0027] Reference Figure 1-4The adjusting component includes an adjusting rod 11, one end of which extends into the interior of the connecting column 5. The outer wall of the adjusting rod 11 is slidably connected to the inner wall of the connecting column 5. A groove 12 is provided on the outer wall of the adjusting rod 11. A second spring 13 is fixedly connected to the inner side wall of the groove 12. A limit block 14 is fixedly connected to one end of the second spring 13. One end of the adjusting rod 11 can move into the interior of the connecting column 5. When the adjusting rod 11 moves into the interior of the connecting column 5, the total length between the connecting column 5 and the adjusting rod 11 becomes shorter, which allows the swing plate 2 to rotate, thereby changing the angle of the swing plate 2.

[0028] Furthermore, one side of the limiting block 14 is an inclined surface, and the outer wall of the limiting block 14 is slidably connected to the inner wall of the groove 12. When the inclined surface of the limiting block 14 is subjected to a force, the limiting block 14 can move into the groove 12.

[0029] Furthermore, one end of the limiting block 14 passes through the limiting channel 10 and extends to the outside of the connecting post 5. The outer wall of the limiting block 14 is slidably connected to the inner wall of the limiting channel 10. The limiting block 14 can play the role of limiting and locking through the limiting channel 10.

[0030] During use, pressing the limiting block 14 will move one end of the limiting block 14 into the limiting channel 10. Then, moving one end of the adjusting rod 11 into the connecting post 5 will cause the inclined surface of the limiting block 14 to move into the groove 12, thereby allowing the adjusting rod 11 to move into the connecting post 5. Since there are several limiting channels 10, the limiting block 14 will act as a limiting engagement when it engages with the corresponding limiting channel 10. This will shorten the total length between the connecting post 5 and the adjusting rod 11, allowing the swing plate 2 to rotate and change its angle. The adjusting rod 11 will not move into the connecting post 5 automatically, and the swing plate 2 will not automatically adjust its angle.

[0031] When one side of the valve body 1 is subjected to a large explosive impact, the swing plate 2 will be impacted and rotate towards the valve body 1. In turn, the swing plate 2 will seal the ventilation opening on the valve body 1, thus playing a role in explosion prevention. After the explosion, the first spring 7 will drive the swing plate 2 to reset, thereby enabling continued ventilation.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
