Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher valve technology, and in particular to a quick-connect fire extinguisher valve. Background Technology

[0002] A quick-connect fire extinguisher valve is a valve device that enables rapid connection or disconnection of fire extinguishers with pipelines and interfaces. Its core feature is that, through a special structural design, it eliminates the cumbersome steps of traditional threaded connections, significantly shortening connection time. Primarily used in the fire protection field, it helps rescuers quickly connect fire extinguishers to spray hoses, extension lines, or other fire extinguishing equipment in emergency firefighting scenarios, reducing operation time and ensuring rapid deployment of firefighting operations. It is especially suitable for situations requiring rapid deployment of multiple fire extinguishers for coordinated operations or where connection efficiency is extremely important, effectively improving firefighting response speed and rescue effectiveness.

[0003] A quick-connect fire extinguisher valve mainly consists of a connecting body, a sealing assembly, a locking mechanism, and operating components. The connecting body, as the basic structure, typically includes a plug end and a socket end that cooperate with each other. The sealing assembly generally consists of sealing rings, sealing gaskets, etc., embedded in the contact surface or internal channel of the connecting body. The locking mechanism is the core part that enables quick connection, and common forms include snap-fit, spring pin, or rotating sleeve. The operating components include wrenches, buttons, and sliding sleeves. These structures work together to ensure that the valve can meet the convenience requirements of quick connection while also ensuring the stability and reliability of the fire extinguishing system under high-pressure operating conditions.

[0004] In existing technologies, fire extinguishing valves typically employ a straight-through structure, relying solely on a locking mechanism to quickly connect or disconnect pipelines. They lack adjustable valve cores, throttling devices, or pressure control components, making it impossible to flexibly adjust the extinguishing agent spray volume according to the actual needs of the fire scene. When facing fires of varying sizes and types, rescuers struggle to control the spray intensity in real time via the valve. This functional limitation impacts the accuracy and effectiveness of fire extinguishing operations, particularly in scenarios requiring precise control of extinguishing agent dosage. Therefore, a quick-connect fire extinguisher valve is proposed to address these issues. Utility Model Content

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a quick-connect fire extinguisher valve, comprising a protective shell 1, which protects internal components and provides an installation base. A second protective shell 2 is fixedly connected to its top, further protecting the internal structure and providing installation space for some components. A sliding column 3 is slidably connected to the inner wall of the second protective shell 2, allowing it to slide up and down within the second protective shell 2 to throttle the hose 10. A button 4 is fixedly connected to the top of the sliding column 3, allowing for operation by pressing... Button 4 can drive the sliding column 3 downward. A support ring 5 is fixedly connected to the outer wall of the sliding column 3. Spring 6 can reset the sliding column 3 by acting on the support ring 5. Spring 6 is sleeved on the outside of the sliding column 3, and spring 6 provides elastic force so that the sliding column 3 can reset when no external force is applied. A sliding plate 7 is fixedly connected to the bottom end of the sliding column 3. The downward movement of the sliding column 3 can drive the sliding plate 7 to move synchronously. Multiple conical throttling baffles 8 are fixedly connected to the bottom end of the sliding plate 7. The movement of the sliding plate 7 can cause the conical throttling baffles 8 to move against the soft surface. The flow rate of the fluid in pipe 10 is regulated. Two slide rails 9 are fixedly connected to the inner wall of the protective shell 1. The slide rails 9 provide guidance and support for the sliding plate 7, ensuring its stable movement. A hose 10 is fixedly connected to the inner wall of the protective shell 1. The hose 10 is used to transport fluids such as fire extinguishing agents. A limiting component is provided on the right side of the hose 10 to prevent the safety pin from being accidentally pulled out. The limiting component can enhance the safety of the fire extinguisher and avoid accidental spraying due to the accidental removal of the safety pin. The top of the spring 6 is fixedly connected to the bottom of the support ring 5 to fix it. One end of spring 6 is designed to allow it to exert its elastic restoring force. The bottom end of spring 6 is fixedly connected to the top of protective shell 1. Protective shell 1 provides support for spring 6 and ensures the effective release of its elastic force. The outer wall of sliding plate 7 is slidably connected to the outer walls of two slide rails 9. Guided by slide rails 9, sliding plate 7 can slide smoothly up and down. The outer wall of conical throttling baffle 8 is slidably connected to the inner wall of hose 10. By sliding inside hose 10, conical throttling baffle 8 can change the channel area of ​​fluid inside hose 10, thereby regulating the flow rate.

[0033] Reference Figure 1 , Figure 2 and Figure 4The limiting assembly includes a handle 11, which controls the opening and closing of the fire extinguishing valve 20 and is a key component for operating the fire extinguisher. Its left side is fixedly connected to the right side of the hose 10, thus achieving connection and fixation with the overall structure. A housing 12 is fixedly connected to the outer wall of the handle 11, protecting internal components such as the damper 13. The damper 13 is fixedly connected to the inner wall of the housing 12, providing damping force to slow the movement speed of the pressure plate 15, thus providing buffering and stabilization. A connecting plate 14 is fixedly connected to the left side of the damper 13, connecting the damper 13 and the pressure plate 15 and transmitting force. The pressure plate 15 is fixedly connected to the left side of the connecting plate 14, limiting the safety pin to prevent accidental removal. The outer wall of the pressure plate 15 is slidably connected to the inner wall of the housing 12, ensuring the pressure plate 15... The damper 13 is equipped with a spring 16 on its outer side, which provides elastic restoring force to assist the pressure plate 15 in resetting. A limit rod 17 is fixedly connected to the inner wall of the outer shell 12. The limit rod 17 guides and limits the movement of the pressure plate 15 to prevent it from deviating. A groove 18 is provided on the inner wall of the outer shell 12. The groove 18 is used to accommodate and cooperate with related components to achieve specific functions. The inner wall of the pressure plate 15 is slidably connected to the outer wall of the limit rod 17. Guided by the limit rod 17, the pressure plate 15 can slide stably within the outer shell 12. A nozzle 19 is fixedly connected to the left side of the protective shell 1. The nozzle 19 is used to spray the extinguishing agent in the fire extinguisher to achieve the fire extinguishing function. A fire extinguishing valve 20 is fixedly connected to the bottom end of the handle 11. The action of the handle 11 can control the opening and closing of the fire extinguishing valve 20, thereby controlling the spraying of the extinguishing agent.

[0034] Working principle: When button 4 is pressed down, button 4 moves sliding column 3 downward, sliding column 3 moves support ring 5 downward, support ring 5 exerts a downward force on spring 6, spring 6 is compressed. At the same time, sliding column 3 moves sliding plate 7 downward, sliding plate 7, guided by slide rail 9, moves conical throttling baffle 8 downward. Conical throttling baffle 8 moves downward inside hose 10, increasing the degree of obstruction of the internal channel of hose 10, at which time the flow rate decreases. Conversely, when button 4 is released, spring 6 releases its elastic force, pushing support ring 5 upward, support ring 5 moves sliding column 3 upward, sliding column 3 moves button 4 upward to reset, and at the same time sliding column 3 moves sliding plate 7 upward, sliding plate 7 moves conical throttling baffle 8 upward, the degree of obstruction of the internal channel of hose 10 by conical throttling baffle 8 decreases, at which time the flow rate increases.

[0035] When the safety pin is inserted along the inner wall of the outer casing 12, it rotates counterclockwise. The safety pin, along the outer wall of the pressure plate 15, first exerts a backward force on the pressure plate 15. Guided by the limit rod 17, the pressure plate 15 slides backward, causing the connecting plate 14 to move backward. The connecting plate 14 exerts a backward force on the second spring 16, compressing the spring. Simultaneously, the connecting plate 14 drives the damper 13, which provides damping force to slow the sliding speed of the pressure plate 15. When the safety pin slides into the inner wall of the groove 18, the second spring 16 releases its elasticity, pushing the connecting plate 14 to the left. The connecting plate 14 then pushes the pressure plate 15 to the left, compressing the pressure plate 15. Under the guidance of the limiting rod 17, the plate 15 slides to the left. At this time, the pressure plate 15 firmly fixes the safety pin in the groove of the recess 18, completing the limiting operation. Conversely, when it is necessary to pull out the safety pin, an outward pulling force is applied to the safety pin and it is rotated clockwise. The safety pin generates a backward force on the pressure plate 15. The pressure plate 15 slides backward and drives the connecting plate 14 backward. The connecting plate 14 compresses the second spring 16 and the damper 13. The damper 13 provides damping force to slow down the action. When the safety pin disengages from the groove of the recess 18 and is pulled out from the inner wall of the outer shell 12, the second spring 16 releases its elastic force, pushing the connecting plate 14 and the pressure plate 15 to reset to the left, completing the unlocking operation.

[0036] 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.
