[0002] Explosion-proof valves are important safety devices widely used in industries such as chemical, petroleum, power, pharmaceutical, and food processing to prevent explosions caused by excessive internal pressure. Their main function is to automatically open and release pressure when the internal pressure reaches a dangerous level, thereby protecting the equipment and operators. Explosion-proof valves come in various types, including threaded and flanged types, to meet the needs of different equipment and working environments. Their design and manufacture must comply with relevant safety standards and specifications to ensure reliable operation under various conditions. Regular inspection and maintenance are essential during use to ensure they are always in optimal working condition.
[0003] Existing explosion-proof valves are widely used, but the structural components of existing explosion-proof valves are all connected by threads, which makes the assembly of explosion-proof plates inconvenient. In addition, most explosion-proof valves have upward exhaust ports, which can easily cause burns to workers during some high-temperature and high-pressure experiments. Therefore, a snap-fit explosion-proof valve is proposed to address the above problems. Utility Model Content

[0023] Please see Figure 1-5 This utility model provides a technical solution:
[0024] A snap-fit explosion-proof valve includes a threaded cylinder 1, with a mounting block 2 fixedly connected to the top of the threaded cylinder 1. The mounting block 2 has a groove 3 that runs from top to bottom through the mounting block 2. Limiting components 4 are symmetrically installed on the front and rear sides of the mounting block 2. A sealing ring 5 is provided at the bottom of the inner side of the groove 3. An explosion-proof plate 6 is provided at the top of the sealing ring 5. A compression cap 7 that communicates with the threaded cylinder 1 is provided above the explosion-proof plate 6. A snap-fit groove 8 is symmetrically provided on the outer side of the compression cap 7. Threaded grooves 9 are symmetrically provided on the left and right sides of the mounting block 2. A screw 10 is spirally connected to the inner side of the threaded groove 9. A vertically installed mounting plate 11 is provided on the outer side of the screw 10. A circular hole 12 that runs from left to right through the mounting plate 11 is provided inside the mounting plate 11. A protective shell 13 is fixedly connected to the top of the mounting plate 11. A water-absorbing component 14 is installed at the top of the protective shell 13.
[0025] The limiting component 4 includes a limiting cylinder 41 fixedly connected to the outside of the mounting block 2. A limiting slide plate 42 is slidably connected to the inside of the limiting cylinder 41. A latching rod 43 is fixedly connected inside the limiting slide plate 42, penetrating the limiting slide plate 42. A baffle 44 is fixedly connected to one end of the latching rod 43. A spring 45 is provided on the outside of the latching rod 43. The design of the limiting component 4 makes the installation of the explosion-proof sheet 6 more convenient, and the installation of the explosion-proof sheet 6 can be completed without the aid of tools. The latching rod 43 penetrates the mounting block 2 and is slidably connected to the mounting block 2. The latching groove 8 is connected to the latching rod 43 by a snap-fit connection. One end of the spring 45 is fixedly connected to the limiting slide plate 42, and the end of the spring 45 away from the limiting slide plate 42 is fixedly connected to the inside of the limiting cylinder 41. Next, the spring 45 resets and drives the buckle rod 43 to insert into the buckle groove 8, thereby limiting and fixing the pressure cap 7. The water absorption assembly 14 includes a telescopic cylinder 141 fixedly connected to the top of the protective shell 13 and penetrating the protective shell 13. The telescopic cylinder 141 is provided with compressed water-absorbing cotton 142 inside. The bottom end of the compressed water-absorbing cotton 142 is provided with a film 143 fixedly connected to the bottom end of the telescopic cylinder 141. The water absorption assembly 14 can absorb the liquid in the gas-liquid mixture and prevent the liquid from splashing and causing burns to the operator. The bottom end of the inner side of the groove 3 is tightly fitted with the bottom end of the sealing ring 5. The top end of the sealing ring 5 is tightly fitted with the bottom end of the explosion-proof sheet 6. The top end of the explosion-proof sheet 6 is tightly fitted with the bottom end of the pressure cap 7. The screw 10 is located inside the round hole 12.
[0026] Workflow: When installing an explosion-proof valve, manually screw the threaded cylinder 1 inside the explosion-proof port of the device. Use a wrench or other tools to tighten the mounting block 2. Then install the explosion-proof disc 6 and pull the baffle 44. At this time, the latching rod 43 and the limiting slide plate 42 slide inside the limiting cylinder 41, and the spring 45 is compressed. Place the sealing ring 5 inside the groove 3 at the top of the mounting block 2, place the explosion-proof disc 6 on the top of the sealing ring 5, and finally insert the clamping cap 7 into the groove 3 and press the clamping cap 7 firmly. At this time, the sealing ring 5 undergoes elastic deformation under force, filling the gap between the explosion-proof disc 6 and the groove 3 until the latching groove 8 on the clamping cap 7 is horizontally aligned with the latching rod 43. Release the baffle 44, and the spring 45 returns to its original position, causing the latching rod 43 and the limiting slide plate 42 to slide inside the limiting cylinder 41 until the latching rod 43 is inserted. The explosion-proof disc 6 can be installed inside the snap-fit groove 8. The design of the limiting component 4 makes the installation of the explosion-proof disc 6 more convenient. The installation of the explosion-proof disc 6 can be completed without the aid of tools. Next, install the protective shell 13. Align the round hole 12 on the mounting plate 11 with the threaded groove 9 horizontally. Insert the screw 10 into the round hole 12 and screw it into the threaded groove 9 to complete the installation of the protective shell 13. When the explosion-proof disc 6 ruptures due to excessive pressure in the device, the gas-liquid mixture is rapidly discharged through the threaded cylinder 1 and the compression cap 7. The protective shell 13 covers the compression cap 7 to prevent the gas-liquid mixture from spraying upward. The gas-liquid mixture ruptures the membrane 143. The compressed absorbent cotton 142 absorbs the liquid in the gas-liquid mixture and expands rapidly, causing the telescopic cylinder 141 to extend. The water absorption component 14 can thus prevent liquid splashing and burns to the operator.
