Description

Technical Field

[0001] This utility model relates to the field of civil defense door processing technology, specifically to an installation structure for a rubber hose type explosion-proof wave valve. Background Technology

[0002] Blast wave vents are protective devices installed at the air inlets and exhaust outlets of engineering projects. They are designed to resist blast waves and reduce their overpressure. They can be categorized into suspended plate blast wave vents, hose-type blast wave vents, and explosion-proof overpressure exhaust valves. They automatically close upon exposure to a nuclear blast wave, protecting the internal ventilation equipment from damage. Hose-type blast wave vents, in particular, close rapidly under blast wave overpressure. The hose deforms, blocking most of the blast wave outside the project. A small portion of the blast wave enters the diffusion chamber at the project's head, further expanding and diffusing until it is reduced to a permissible safe pressure. Therefore, hose-type blast wave vents not only provide ventilation but also have a certain wave-damping effect.

[0003] For example, patent CN207453815U discloses a hose-type blast wave valve. The installation method of the blast wave valve usually involves setting several ventilation holes on the door leaf, welding a base inside the ventilation holes, and installing the hose-type blast wave valve onto the base through clamps or slot blocks. The existing base is a cylindrical structure, which makes it difficult to ensure consistent height when the base is welded into the ventilation holes, and the base is prone to tilting. The installed blast wave valve will also tilt, and the valve cannot close well when subjected to shock waves, affecting the installation and use effect of the blast wave valve. Utility Model Content

[0004] To address the shortcomings of existing technologies, the present invention provides an installation structure for a hose-type explosion-proof wave valve, resolving the issues of inconsistent base height and easy tilting in existing explosion-proof wave valves.

[0005] To solve the above problems, the technical solution adopted by this utility model is: an installation structure for a hose-type explosion-proof wave valve, including a grid frame, a panel and a base. The panel is welded and fixed to the surface of the grid frame, and the panel is provided with a number of evenly spaced circular holes. The base is cylindrical and welded into the circular holes. A step is provided at the bottom of the base where it mates with the circular holes.

[0006] The beneficial effects of this solution are: by setting a step at the bottom of the existing cylindrical base, the step fits into the round hole on the panel during welding, and the end face of the step abuts against the panel surface, which can realize the rapid positioning of the base, ensure that the base is perpendicular to the panel surface and that the base height is consistent, and improve production efficiency.

[0007] Furthermore, the base is provided with two parallel arc-shaped plates, the top of which protrudes from the upper surface of the base. When the hose is squeezed and adhered to the upper surface of the arc-shaped plate under the impact of the shock wave, the arc-shaped plate provides a certain support for the hose, reducing the possibility of the hose sinking into the inner cavity of the base.

[0008] Furthermore, the base is made of seamless steel pipe by turning. Turning can ensure the accuracy of the dimensions of the bottom step of the base, and ensure that the height of the base and the dimensions of the step are consistent.

[0009] Furthermore, the step and the round hole are fitted with a clearance, allowing the base to be quickly placed into the round hole and accurately positioned during welding, thus improving processing efficiency. Attached Figure Description

[0014] 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.

[0015] Implementation, for example, attached Figures 1 to 3 As shown: An installation structure for a hose-type explosion-proof wave valve includes a grid frame 1, a panel 2, and a base 3. The panel 2 is welded and fixed to the surface of the grid frame 1, which provides support for the panel 2 and ensures its flatness. The panel 2 has several evenly spaced circular holes 1, which serve as ventilation holes. The base 3 is cylindrical and welded into the circular holes 1. A step 31 is provided at the bottom of the base 3 where it mates with the circular holes 1. Due to the step 31, the step 31 is placed inside the circular holes 1 during welding, which allows for quick positioning of the base 3, ensuring that the base 3 is perpendicular to the panel 2 and that the height of the base 3 is consistent, thereby improving production efficiency.

[0016] The base 3 has two parallel arc-shaped plates 4 inside, with the top of the arc-shaped plates 4 protruding from the upper surface of the base 3. When the hose is squeezed and adhered to the upper surface of the arc-shaped plates 4 under the impact of the shock wave, the arc-shaped plates 4 can provide a certain support for the hose, reducing the possibility of the hose sinking into the inner cavity of the base 3. The base 3 is made of seamless steel pipe by turning, which can ensure the accurate dimensions of the bottom step 31 of the base 3. The step 31 is clearance-fitted with the round hole 1, which allows the base 3 to be quickly placed into the round hole 1 and accurately positioned during welding, improving processing efficiency.

[0017] The specific implementation process is as follows: When the base 3 is welded into the round hole 1 on the panel 2, the step 31 at the bottom of the base 3 matches the round hole 1, and the end face of the step 31 abuts against the surface of the panel 2 to achieve the positioning of the base 3, ensuring that the base 3 is perpendicular to the panel 2, and that the height of several bases 3 is consistent. The rubber tube type explosion-proof wave valve can be installed on the base 3 by means of clamps or quick-fitting grooves.
