Description

Technical Field

[0001] This utility model relates to the field of building safety device technology, and in particular to a venting membrane window. Background Technology

[0002] An explosion-proof window is a type of window specifically designed to safely release pressure under conditions of explosion or extreme pressure. It is primarily used in buildings or facilities with high safety requirements, such as chemical plants, data centers, laboratories, and military installations. The purpose of this type of window is to prevent secondary injuries or further damage caused by the window breaking in the event of an explosion wave or excessive pressure.

[0003] The working principle of explosion-proof membrane windows is essentially to prevent window rupture in the event of an explosion or pressure surge using specially designed membrane materials. The membrane's deformation and pressure release functions protect the safety of buildings and people. The key lies in the strength, elasticity, and pressure release capability of the membrane material, which can quickly dissipate the pressure generated by an explosion, preventing further damage to buildings and people.

[0004] Traditional explosion-proof diaphragm windows require complete adjustment of the entire system when the diaphragm is damaged, which not only increases maintenance costs but also leads to long downtime. This design flaw results in high maintenance costs, especially in environments where explosions or pressure changes occur frequently. Therefore, an explosion-proof diaphragm window is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a venting membrane window, which aims to improve the problems of increased maintenance costs and long downtime in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An explosion-proof diaphragm window includes an explosion-proof sheet support plate, a protective film installed on one side of the explosion-proof sheet support plate, an explosion-proof diaphragm installed on one side of the explosion-proof sheet support plate, a sealing sheet installed on one side of the explosion-proof diaphragm, a reinforcing frame installed on both sides of the explosion-proof sheet support plate, and a retainer installed on both sides of the explosion-proof sheet support plate.

[0008] As a further description of the above technical solution:

[0009] The reinforcing frame is threadedly connected to the retainer on the side adjacent to it, and a nut is threadedly connected to the external thread of the connector;

[0010] As a further description of the above technical solution:

[0011] A groove is provided on one side of the explosion relief support plate, and the outer part of the explosion relief diaphragm is installed on the inner wall of the groove;

[0012] As a further description of the above technical solution:

[0013] The sealing sheet is made of silicone, and the explosion relief support plate is made of aluminum alloy.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the combination of a diaphragm, a reinforcing frame, and a retainer enables directional pressure relief, ensuring rapid and effective release of explosion pressure and reducing the risk of damage to indoor structures. The diaphragm ruptures under a preset pressure, releasing the impact force while the protective membrane effectively blocks flying debris, enhancing safety. Secondly, the silicone sealing sheet ensures airtightness, preventing external gases or contaminants from entering and guaranteeing system integrity. The reinforcing frame and retainer form a rigid support through threaded connections between connectors and nuts, preventing structural deformation and enhancing overall stability. Finally, the diaphragm can be quickly replaced, reducing maintenance time and ensuring efficient system operation. Overall, this design effectively improves the reliability and safety of the explosion-proof system, reduces potential damage from explosions, and allows for individual component replacement, thereby reducing downtime and maintenance costs during inspection and maintenance.

[0020] 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.

[0021] Reference Figures 1 to 2This utility model provides an embodiment of a pressure relief membrane window, including a pressure relief support plate 2. The pressure relief support plate 2 is made of high-strength aluminum alloy, which provides stable pressure support while ensuring lightweight design, laying a rigid foundation for the overall structure. A protective film 5 is installed on one side of the pressure relief support plate 2. The multi-layer composite protective film 5 covers the surface of the support plate and forms a physical barrier during pressure relief, significantly reducing the diffusion range of broken fragments and improving the safety of the surrounding area. A pressure relief diaphragm 4 is installed on one side of the pressure relief support plate 2. The pressure relief diaphragm 4 is calibrated with a pressure threshold and can quickly respond to rupture in the instant of overpressure, achieving a dynamic balance between pressure release and structural protection.

[0022] A groove is provided on one side of the explosion relief diaphragm support plate 2. The specially designed V-shaped groove is optimized through structural mechanics to form a directional stress concentration area at the edge of the explosion relief diaphragm 4, which precisely controls the rupture path. The outer part of the explosion relief diaphragm 4 is installed on the inner wall of the groove. The explosion relief diaphragm 4 and the groove adopt an interference fit, which not only ensures the stability of the installation, but also avoids the risk of pre-damage caused by assembly stress. A sealing sheet 3 is installed on one side of the explosion relief diaphragm 4. The elastic silicone sealing sheet 3 fills the gap of the component through deformation, maintains stable sealing performance under wide temperature range conditions, and prevents daily media leakage. The sealing sheet 3 is made of silicone, which has both aging resistance and high resilience. It continuously compensates for the gap of the sealing surface when the pressure fluctuates, ensuring long-term airtightness.

[0023] The explosion relief support plate 2 is made of aluminum alloy. The aluminum alloy material gives the support plate excellent impact resistance and toughness, and can withstand the impact of explosion pressure without plastic deformation. Both sides of the explosion relief support plate 2 are equipped with a reinforcing frame 1. The reinforcing frame 1 has a strong rib layout design, which significantly improves the overall bending stiffness and controls the structural deformation during the pressure relief process within a safe threshold. Both sides of the explosion relief support plate 2 are equipped with retainers 6. The retainers 6 adopt an adaptive adjustment structure to compensate for the tolerance of the mounting surface and ensure that each component is always in the best fit. The reinforcing frame 1 and the retainer 6 are connected by threads to the adjacent side with connectors 7. The multi-phase distributed connectors 7 form a three-dimensional constraint system, which synergistically enhances the rigidity of the connection node and effectively suppresses the risk of vibration loosening. The external threads of the connectors 7 are connected with nuts. The anti-loosening nuts have a pre-tightening force optimized design to maintain a stable clamping force under dynamic load and ensure the reliability of the connection during quick assembly and disassembly.

[0024] Working principle: This explosion-proof diaphragm window achieves directional pressure relief through a stable structure consisting of an explosion-proof diaphragm 4 (which ruptures under preset pressure), a reinforcing frame 1, and a retainer 6. Under normal conditions, the aluminum alloy explosion-proof diaphragm support plate 2 fixes the explosion-proof diaphragm 4 through grooves on both sides, and the silicone sealing sheet 3 fills the gaps to ensure airtightness. When the internal explosion pressure rises sharply, the explosion-proof diaphragm 4 ruptures preferentially along the groove design direction, and the impact force is released outward through the explosion-proof window. The protective film 5 can block the flying debris. The reinforcing frame 1 and the retainer 6 form a rigid support through the threaded connection of the connector 7 and the nut to prevent structural deformation. After pressure relief, the connector 7 can be removed to replace the diaphragm and quickly restore the system's airtightness. The entire device reduces the risk of damage to the indoor structure from the explosion through directional pressure relief.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
