Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a nozzle valve with reinforcing ribs. Background Technology

[0002] Highly efficient and reliable fire extinguishing equipment is a key line of defense for protecting life and property. Among them, nozzles and valves are the core components of fire extinguishing modules, and their performance directly affects the success or failure of fire extinguishing operations. With the increasing scale and complexity of modern buildings and the development of industrial production towards large-scale and refined production, fire hazards have increased and the difficulty of fire fighting has increased significantly, which has placed stringent requirements on the performance of fire extinguishing modules.

[0003] Fire nozzle valves typically consist of a valve body, valve core, valve seat, drive unit, sealing components, and reinforcing ribs. The valve body serves as the main body and has an internal channel. The valve core cooperates with the valve seat to open or close the channel. The drive unit (such as a manual, electric, or pneumatic device) controls the movement of the valve core, and the sealing components ensure the valve's tightness when closed.

[0004] While nozzle valves currently play a positive role in the fire protection industry, their structural strength is a significant issue. Fire protection modules often experience water pressures of several megapascals. Traditional valves, subjected to continuous high-pressure impacts, are prone to stress concentration and deformation in critical components such as the valve body and valve core, leading to sealing failure. Frequent opening and closing or prolonged high pressure can cause fatigue cracks in valve connections and weak sections, resulting in leaks, component breakage, and other malfunctions. Furthermore, the high temperatures at fire scenes accelerate material degradation, weakening structural strength and causing valves to malfunction at critical moments, impacting firefighting efficiency, delaying rescue efforts, and threatening life and property. Therefore, a nozzle valve with reinforcing ribs is proposed to address these problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a nozzle valve with reinforcing ribs, aiming to improve the problem of insufficient structural strength of nozzle valves in the prior art.

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

[0007] A nozzle valve with reinforcing ribs includes a lower handle, an upper handle rotatably connected to one side of the lower handle, a valve tube fixedly connected to the bottom of the lower handle, a connecting post fixedly connected to the bottom of the valve tube, a sealing ring fixedly connected to the outer wall of the connecting post, threaded threads on the outer wall of the connecting post, a connecting tube fixedly connected to the bottom of the threaded threads, reinforcing ribs fixedly connected to the outer wall of the valve tube, and a protective component fixedly connected to the outer wall of the valve tube.

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

[0009] The protective assembly includes a fuse, one side of which is fixedly connected to the outer wall of the valve pipe, a connector is fixedly connected to the bottom of the lower handle, and an anti-slip component is fixedly connected to the outer wall of the lower handle.

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

[0011] One side of the connector is fixedly connected to one side of the fuse, and the top of the fuse is fixedly connected to the bottom of the lower handle.

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

[0013] The bottom of the fuse is fixedly connected to the top of the reinforcing rib, and the cross-sectional shape of the valve pipe is L-shaped.

[0014] As a further description of the above technical solution:

[0015] The cross-sectional shape of the connecting pipe is hexagonal, and the cross-sectional shape of the upper handle is Z-shaped;

[0016] As a further description of the above technical solution:

[0017] The top of the screw thread contacts the bottom of the sealing ring, and the bottom of the reinforcing rib is fixedly connected to the top of the connecting column;

[0018] As a further description of the above technical solution:

[0019] The lower handle has an arc-shaped cross-section, and the inner wall of the connecting pipe is provided with a threaded groove.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the nozzle valve can be driven to operate by pressing the upper handle to make it contact the lower handle. The anti-slip design can firmly hold the lower handle when pressing to prevent it from slipping out of the hand. The connecting column makes the valve components more stable. The screw threads can tightly fix the valve to other components. The sealing ring can form a tight seal to prevent water leakage. The addition of reinforcing ribs greatly improves the structural strength of the valve, making it able to withstand the impact of high-pressure water flow, reducing the risk of deformation during long-term use, allowing the valve to maintain stable performance during operation, and effectively improving the efficiency of fire extinguishing operations.

[0022] 2. In this utility model, thanks to the design of the connecting pipe, the nozzle valve can be smoothly connected to the external pipeline, ensuring the continuity of fluid transportation and enabling normal operation. The valve pipe optimizes the internal flow channel, reduces water flow resistance, and allows the valve to stably and continuously control the fluid output. The fusible link breaks first to release stress when the valve encounters abnormal overpressure, preventing damage to the main structure. The connecting part provides a solid installation foundation for the fusible link, ensuring that it can reliably perform its protective function. These designs work together to significantly extend the service life of the nozzle valve and enable it to maintain stable performance under complex working conditions. Attached Figure Description

[0029] 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.

[0030] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a nozzle valve with reinforcing ribs, including a lower handle 1. The lower handle 1 serves as the basic component for operating the nozzle valve, providing a gripping position for easy valve operation. An upper handle 2 is rotatably connected to one side of the lower handle 1. The upper handle 2 cooperates with the lower handle 1, and the valve is opened and closed by rotation to control the flow of fluid. A valve pipe 3 is fixedly connected to the bottom of the lower handle 1. The valve pipe 3 is the main channel for fluid flow, determining the working path of the valve and ensuring the stable and continuous operation of the nozzle valve. A connecting post 4 is fixedly connected to the bottom of the valve pipe 3. The connecting post 4 enhances the connection strength between the various components of the valve, making the entire nozzle valve structure more stable and improving overall reliability. A sealing ring 5 is fixedly connected to the outer wall of the connecting post 4. The sealing ring 5 plays a sealing role when the valve is connected to other components, preventing fluid leakage and ensuring the sealing performance and safety of the connection.

[0031] The outer wall of the connecting column 4 is provided with threaded threads 6, which are used for threaded connection with other components. Through the threaded engagement, the nozzle valve can be firmly fixed to other equipment. The bottom of the threaded threads 6 is fixedly connected to the connecting pipe 7. The connecting pipe 7 is a key component for connecting the valve to external equipment and for fluid output, ensuring normal valve operation and realizing fluid transmission. The outer wall of the valve pipe 3 is fixedly connected with reinforcing ribs 8. The reinforcing ribs 8 increase the structural strength of the valve pipe 3, reduce the deformation of the valve caused by pressure and other factors during use, and greatly improve the efficiency and stability of valve operation. The outer wall of the valve pipe 3 is fixedly connected with protective components to enhance the safety of the valve. To ensure safety and reliability and prevent valve damage under abnormal conditions, the protective components include a fusible link 9. One side of the fusible link 9 is fixedly connected to the outer wall of the valve pipe 3. When the valve encounters abnormal overpressure, the fusible link 9 will break first, releasing local stress and protecting the main structure of the valve from damage. A connector 10 is fixedly connected to the bottom of the lower handle 1. The connector 10 is used to fix the fusible link 9, ensuring that the fusible link 9 is firmly installed on the valve and can play its role at critical moments. An anti-slip part 11 is fixedly connected to the outer wall of the lower handle 1. The anti-slip part 11 increases the friction of the surface of the lower handle 1, so that the user can firmly grip the lower handle 1 when pressing the upper handle 2, preventing it from falling off and improving operational safety.

[0032] Reference Figures 2 to 4One side of the connector 10 is fixedly connected to one side of the fuse 9. This connection method ensures that the fuse 9 is installed firmly, maintaining stability during valve operation and enabling it to perform its protective function normally in critical moments. The top of the fuse 9 is fixedly connected to the bottom of the lower handle 1, and the bottom is fixedly connected to the top of the reinforcing rib 8, so that the fuse 9 is tightly connected to all valve components, ensuring uniform stress and optimal protective effect. The valve pipe 3 has an L-shaped cross-section, which optimizes the fluid flow path and enhances the structural strength of the valve pipe 3, ensuring stable fluid flow. The connecting pipe 7 has a hexagonal cross-section, which facilitates installation and disassembly using tools and can withstand greater torque, ensuring a firm connection. The cross-sectional shape of the handle 2 is Z-shaped. This unique shape design conforms to ergonomics, making it easy for users to apply force to rotate and realize the opening and closing operation of the valve. The top of the screw thread 6 contacts the bottom of the sealing ring 5, ensuring that the sealing ring 5 is in the correct position during the threaded connection, effectively playing a sealing role and preventing leakage at the connection. The bottom of the reinforcing rib 8 is fixedly connected to the top of the connecting column 4, so that the reinforcing rib 8 and the connecting column 4 form a stable support structure, further enhancing the overall structural strength of the valve. The cross-sectional shape of the lower handle 1 is arc-shaped, conforming to the curve of the hand, improving grip comfort, and facilitating long-term operation by the user. The inner wall of the connecting tube 7 is provided with threaded grooves, which facilitates connection with other threaded parts, enabling quick assembly and disassembly and improving ease of use.

[0033] Working principle: Pressing the upper handle 2 brings the upper handle 2 into contact with the lower handle 1, allowing the nozzle valve to operate normally. Thanks to the anti-slip part 11, the lower handle 1 can be firmly gripped when the upper handle 2 is pressed, preventing it from falling off. Thanks to the connecting column 4, the entire nozzle valve structure is more robust. Thanks to the screw thread 6, the entire nozzle valve can be firmly fixed to other components. Thanks to the sealing ring 5, the entire nozzle valve can be firmly sealed when fixed to other components. Thanks to the reinforcing rib 8, the structural strength of the entire nozzle valve is greatly improved, resulting in a significant increase in the operating efficiency of the entire nozzle valve during operation. Thanks to the connecting pipe 7, the operation of the entire nozzle valve can proceed normally. Thanks to the valve pipe 3, the operation of the entire nozzle valve can be stable and continuous. Thanks to the fusible link 9, when the valve encounters abnormal overpressure, the fusible link 9 will break first, releasing local stress and preventing damage to the main structure. Thanks to the connecting part 10, the installation of the fusible link 9 is more secure, thereby greatly extending the service life of the entire nozzle valve.
