[0023] In the embodiment, as shown in Figure 1 and Figure 2 , the diameter of the bottom end of the elastic clamping piece 104 is greater than the diameter of the sealing rubber ring 101.

[0024] In the embodiment, as shown in Figure 1 and Figure 3 , the pressure relief valve 5 comprises a chute pipe 501, the top wall of the chute pipe 501 is provided with a compression spring piece B 502, and the bottom end of the compression spring piece B 502 is provided with a sealing sleeve 503.

[0025] In the embodiment, as shown in Figure 1 and Figure 3 , the outer wall of the pressure relief pipe 4 is provided with a plurality of pressure relief holes 401.

[0026] In the embodiment, as shown in Figure 1 and Figure 4As shown, the first protective netting 6 includes several first support rods 601, a first telescopic net cover 602 is provided between the several first support rods 601, and a first support plate 603 is provided at the bottom end intersection of the several first support rods 601. The second protective netting 7 includes several second support rods 701, a second telescopic net cover 702 is provided between the several second support rods 701, and a second support plate 703 is provided at the bottom end intersection of the several second support rods 701.

[0027] In this embodiment, as Figure 1 and Figure 4 As shown, magnetic absorbing pieces are provided on the opposite sides of the first support rod 601, the second support rod 701, the first support plate 603, and the second support plate 703.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the working process of this explosion-proof flask during use is as follows:

[0029] First, the operator picks up the first protective net sleeve 6 and places it on one side of the outer surface of the bottle body 3. Then, the second protective net sleeve 7 is placed on the other side of the outer surface of the bottle body 3, ensuring that the two sets of first support rods 601 and second support rods 701, as well as the first support plate 603 and second support plate 703 on opposite sides, are in contact and aligned. At this point, the two are automatically attracted and fixed by their respective magnetic suction pieces, thus forming a complete protective cover. Next, the pressure relief valve 5 is installed, with its sealing sleeve 503 inserted obliquely into the pressure relief pipe 4, so that the outer wall of the sealing sleeve 503 can tightly fit against the inner wall of the pressure relief pipe 4, completely blocking the several pressure relief holes 401 opened on the outer wall of the pressure relief pipe 4. At this point, the operator can add water through the bottle neck 2. Chemical reagents are applied, and then the sealing ring 101 of the safety plug 1 is aligned with the opening of the narrow neck 2 and inserted vertically inside. At the same time, the pressure rod 106 is manually pressed down, thereby pushing the compression spring A103 and the elastic clip 104 located at the bottom of the pressure rod 106 to slide down along the inner wall of the slide tube 102. When the elastic clip 104 is completely disengaged from the slide tube 102, its bottom opening will expand outward due to the release of the restriction, and drive the elastic abutment ring 105 located on its outer side to expand synchronously, so that it abuts against the inner side of the sealing ring 101, thereby making the sealing ring 101 tightly fit against the inner wall of the narrow neck 2, completing the seal. Then the spherical bottle 3 can be heated for the experiment. During this period, when the pressure inside the spherical bottle 3 reaches When the initial warning value is reached, the gas pressure will first act on the safety plug 1 system. The gas pressure will push the elastic locking element 104 upward, causing the compression spring element A103 to be compressed and contracted simultaneously. This causes the elastic locking element 104 and the elastic retaining ring 105 to gradually move upward and slide into the slide tube 102, thus creating a tiny gap between the sealing ring 101 and the narrow bottle neck 2. At this time, the gas will be slowly released through the tiny gap. When the pressure inside the spherical bottle 3 continues to rise to the dangerous value, the pressure relief valve 5 system will be activated. The high-pressure gas will enter the interior of the pressure relief pipe 4 as it flows through it and force open the sealing sleeve 503, causing the sealing sleeve 503 to be pushed along the pipe wall of the pressure relief pipe 4. During this process, the gas at the top of the sealing sleeve 503... The compression spring B502 will contract and deform under pressure until the sealing sleeve 503 releases the blockage of the pressure relief hole 401, allowing gas to be quickly discharged from the pressure relief hole 401. Because the pressure relief pipe 4 is installed at an angle, the ejected gas will diffuse in a fan shape, greatly reducing the impact force. After the pressure drops, the compression spring B502 will automatically reset the sealing sleeve 503 through its own rebound property, restoring a completely sealed state. In the event of an accident causing the entire bottle to rupture, the broken glass fragments will be firmly bound between the first telescopic mesh 602 and the second telescopic mesh 702, preventing the fragments from scattering. The safety plug 1 provides automatic pressure regulation, ensuring that when the pressure inside the bottle is normal...The tension of the elastic retainer 104 keeps the elastic abutment 105 in an expanded state, ensuring a complete seal. Once the pressure exceeds the set value, the air pressure will intelligently push the elastic retainer 104 to contract, forming a controllable pressure relief channel, balancing sealing and safety. The sealing ring 101 and the elastic abutment 105 constitute a dual sealing system. The sealing ring 101 provides a static seal, while the elastic abutment 105 generates dynamic sealing pressure to maintain an effective seal. At the same time, controllable pressure relief can be achieved through the gradual compression of the compression spring A103. When the pressure increases, the pressure relief gap will slowly expand with the increase in pressure, avoiding liquid boiling caused by a sudden drop in pressure. During the movement of the sealing sleeve 503, the compression spring B502 at the top of the pressure relief valve 5 will be gradually compressed. The compression process plays a buffering role, making the pressure relief process gradual. The pressure relief valve 5 operates gradually, rather than erupting suddenly. As the sealing sleeve 503 moves and gradually exposes the pressure relief hole 401, the high-pressure gas can be easily discharged in a fan-shaped pattern through the pressure relief hole 401, greatly reducing the impact force and danger of the gas jet. Simultaneously, the reset mechanism of the pressure relief valve 5 relies entirely on the elastic memory function of the compression spring B502, accurately pushing the sealing sleeve 503 back to its original position and resealing the pressure relief hole 401 without any manual intervention. The protective system composed of the first protective mesh sleeve 6 and the second protective mesh sleeve 7 effectively intercepts large glass fragments generated when the bottle breaks, preventing them from flying and injuring people. Furthermore, the magnetic connection between the two protective mesh sleeves ensures quick positioning and fixation during installation, while also generating controllable buffer displacement upon impact and effectively dissipating impact energy through the sliding friction of the magnetic mesh.
