Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher valves, specifically to a fire extinguisher valve device suitable for large-diameter gas cylinders. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool. It contains chemicals used to extinguish fires. Fire extinguishers are common fire-fighting equipment, stored in public places or areas where fires may occur. Different types of fire extinguishers contain different components and are designed for different types of fires.

[0003] In actual firefighting scenarios, the required extinguishing agent spray rate varies significantly depending on the fire situation: for small-scale fires in the early stages, a stable medium flow rate is required to accurately control the fire and avoid excessive consumption of extinguishing agent; while in emergency situations where the fire is spreading rapidly, the maximum flow rate is required to quickly suppress the fire and prevent the disaster from escalating.

[0004] Existing fire extinguishers can only provide a single spray rate and cannot dynamically adjust according to the fire situation. This limitation of a single discharge capability makes the valves insufficiently adaptable to complex fire situations. Therefore, those skilled in the art have provided a fire extinguisher valve device suitable for large-diameter gas cylinders to solve the problems mentioned in the background art.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0026] like Figures 1-6 As shown, this embodiment provides a fire extinguisher valve device suitable for large-diameter gas cylinders, including a valve body 1. A handle 2 is installed on the side of the valve body 1, and a pressure handle 3 is rotatably connected to the upper end of the handle 2. A connecting groove 4 is opened in the valve body 1, and a conveying groove 5 is opened at the upper end of the connecting groove 4. A spray hole 7 is opened on the side of the conveying groove 5, and the spray hole 7 penetrates the valve body 1. A circular groove 8 is opened on the inner wall of the spray hole 7. A cavity 6 is provided on the upper side of the conveying groove 5, and a cavity 9 is provided on the left side of the circular groove 8. A valve is installed inside the connecting groove 4. A valve core 10 has a valve stem 11 mounted on its upper end, passing through the cavity 6 and the valve body 1. A movable plate 12 is mounted on the outer surface of the valve stem 11 and is slidably connected within the cavity 6. A spring 13 is provided on the lower side of the movable plate 12 and is sleeved on the outer surface of the valve stem 11. A rotating plate 14 is rotatably connected inside the circular groove 8. A through hole 15 is opened inside the rotating plate 14, and the diameter of the through hole 15 is the same as the diameter of the ejection hole 7. Several straight holes are opened inside the rotating plate 14. A tapered hole 16 of different diameters is provided. A bevel gear 17 is installed on the side of the rotating plate 14 and is located in the cavity 9. The bevel gear 17 meshes with the bevel gear 18. A rotating shaft is installed on the side of the bevel gear 18 and passes through the valve body 1 to be fixedly connected to the rotating block 19. A storage cavity 20 is provided inside the rotating block 19. A slider 21 is slidably connected inside the storage cavity 20. A spring 22 is installed at one end of the slider 21 and a locking block 23 is installed at the other end of the slider 21. The locking block 23 passes through the side of the rotating block 19. The clockwise end face of the locking block 23 is arc-shaped. A pointing block 24 is installed on the side of the rotating block 19. A fixing ring 25 is slidably fitted on the outer surface of the rotating block 19 and is fixed to the side of the valve body 1. Several slots 26 are opened on the inner wall of the fixing ring 25. The number of slots 26 is equal to the sum of the number of through holes 15 and the number of tapered holes 16. Several opening degree labels 27 are installed on the side of the fixing ring 25. The number of opening degree labels 27 is the same as the number of slots 26.

[0027] The working principle of this utility model is as follows: The opening degree of the fire extinguisher spray is adjusted according to different fire conditions. Rotating the rotating block 19 clockwise causes the locking block 23 to rotate clockwise and contact the inner wall of the locking groove 26, compressing the locking block 23 into the storage cavity 20. Simultaneously, the locking block 23 pushes the slider 21 to compress the second spring 22. At the same time, the rotating block 19 drives the second bevel gear 18 to rotate via the rotating shaft. The second bevel gear 18 meshes with the first bevel gear 17, causing the rotating plate 14 to rotate, thus rotating the through hole 15 or the conical hole 16 to the position of the spray hole 7. Simultaneously, the rotating block 19... 9 drives the locking block 23 to the corresponding slot 26 position, causing the spring 22 to push the slider 21 and locking block 23 to reset. The locking block 23 is locked into the slot 26, fixing the position of the rotating block 19. Observe the opening degree label 27 pointed to by the pointing block 24. It can quickly control the required through hole 15 or conical hole 16 to rotate to the position of the spray hole 7, thereby adjusting the spray rate of the extinguishing agent. The spray rate can be switched through simple operation, allowing users to flexibly adjust according to the actual fire situation, adapt to different scales and types of fire scenarios, and enhance the applicability of the fire extinguisher in complex fire extinguishing environments.
