Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to a high-pressure fine water mist nozzle. Background Art

[0002] High-pressure nozzles are different from ordinary shower heads. High-pressure nozzles are generally used in fire extinguishing systems.

[0003] For example, Chinese patent document CN220336782U discloses a protective, airtight partition door for a steel structure workshop. A fire extinguishing assembly is installed at the top of the door frame. The assembly includes a water pipe and multiple high-pressure nozzles. When a fire occurs, water is delivered through the water pipe to the high-pressure nozzles, where it is sprayed out to extinguish flames around the door frame.

[0004] However, in the above solution, the water spraying volumes of the multiple high-pressure nozzles are the same. In actual use, some locations do not require a large water spraying volume, and such a setting will result in a waste of water resources. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the flow rate of the high-pressure nozzle in the prior art cannot be controlled, thereby providing a high-pressure fine water mist nozzle.

[0006] In order to solve the above technical problems, the utility model provides a high-pressure fine water mist nozzle, including a pipe body, a pressurized channel, a nozzle and a valve; the pipe body has a pressurized channel inside; the nozzle is connected to the pipe body and communicates with the outlet of the pressurized channel; the valve is connected to the pipe body; the valve has a valve core, which extends into the pressurized channel and can move along the radial direction of the pressurized channel to adjust the flow area of the pressurized channel.

[0007] The utility model provides a high-pressure fine water mist nozzle, which can adjust the flow area of the pressurized channel by moving the valve core radially along the pressurized channel, thereby flexibly adjusting the water mist pressure and flow rate of different nozzles to meet the needs of different scenarios and avoid wasting water resources.

[0008] Optionally, a filter plate is provided in the pipeline body, and the filter plate is arranged upstream of the valve.

[0009] The provision of the filter plate can prevent impurities from damaging the valve, maintaining smooth valve operation; reduce maintenance times, ensure stable system operation, and improve system reliability; protect downstream equipment, prevent equipment blockage, and improve equipment performance and life; and facilitate maintenance and cleaning, reducing maintenance costs.

[0010] Optionally, the inlet section of the pressurized channel has a flared structure, and the filter plate is mounted on the inlet section.

[0011] By setting the flared structure, the cross-sectional area of the inlet section is increased, which is equivalent to increasing the filtration area and improving the filtration efficiency; the flared structure also allows the fluid to flow more smoothly, avoids excessive local pressure, reduces pressure loss, and improves the energy efficiency of the system; the flared structure provides a more spacious space, making the installation and maintenance of the filter plate easier; installing the filter plate at the flared structure can effectively intercept impurities in the fluid, prevent nozzle blockage, reduce the impact of impurities on the pressurized channel and downstream equipment, and improve the stability and reliability of the system.

[0012] Optionally, the valve further includes a valve stem and a valve seat, the valve seat is detachably mounted on the pipeline body, the valve stem is threadedly connected to the valve seat, and an end of the valve stem is connected to the valve core.

[0013] The threaded connection between the valve stem and valve seat allows precise adjustment of the valve core position to control fluid flow. The valve stem extends outside the valve, allowing for simple and intuitive manual rotation without the need for additional electrical or pneumatic equipment, reducing costs and maintenance. The removable valve seat eliminates the need to replace the entire valve in the event of damage, reducing repair costs and time, workload, and impact on production. The removable seat allows for selection of materials and types to suit specific conditions, enhancing versatility.

[0014] Optionally, the valve stem and the valve core are connected via a bearing.

[0015] By setting bearings in the valve core, the operating torque can be reduced, labor intensity can be reduced, wear can be reduced, and the service life of the valve core can be increased. Stable motion support is provided to make relative motion more precise, and sticking or shaking is eliminated to make the valve action smoother. Specially designed bearings can work under harsh working conditions to ensure reliable connection. Corrosion-resistant materials can improve the corrosion resistance of valves working in corrosive media, and bearings can be replaced separately when they fail, thereby reducing maintenance costs and time. The bearings have a simple structure and are easy to maintain. Daily inspection and lubrication operations can ensure the normal operation of the bearings.

[0016] Optionally, the valve further includes a handle connected to the top end of the valve stem and configured to drive the valve stem to rotate.

[0017] The addition of a handle to the valve improves operational convenience. Turning the handle easily rotates the valve stem, making valve opening and closing operations simpler and more direct. The handle design also increases torque, making it easier for operators to rotate the valve.

[0018] Optionally, the valve seat is annular and is surrounded and connected to the pipeline body.

[0019] By connecting the annular valve seat to the pipe body in an encircling manner, the force acting on the valve seat can be evenly distributed around the pipe, thereby reducing local stress concentration and lowering the risk of valve damage. Compared with single-sided or point-type connections, the encircling connection has a larger contact area and a more secure connection, capable of withstanding greater tension, torsion, and vibration. The annular valve seat and the pipe body can form a complete annular sealing surface, which can effectively prevent fluid leakage and improve the reliability of the seal. The annular valve seat has a simple design and is easy to install. It does not require complex tools and professional techniques, saving installation time and costs. In the event of a fault, disassembly is very convenient and can be directly removed from the pipe for inspection or replacement, with minimal impact on the pipeline system.

[0020] Optionally, the outer surface of the valve seat has a mounting plane, and the mounting plane has a threaded hole for passing the valve stem.

[0021] Providing a mounting surface on the valve seat surface provides a stable foundation for valve installation. The large contact area between the surface and the mounting area disperses pressure, preventing the valve from shaking or shifting during operation, thereby improving valve stability and proper operation. The provision of a mounting surface also facilitates determining the installation direction and position, reducing errors and improving installation efficiency. The threaded hole, in conjunction with the valve stem, precisely controls the stem position. Rotating the stem allows for precise adjustment of the valve opening, thereby controlling fluid flow. Threaded connections offer high reliability and sealing properties, ensuring valve sealing and safe system operation even in harsh environments. Furthermore, the threaded connection design facilitates valve maintenance and component replacement, reducing maintenance costs and time.

[0022] Optionally, the outer side wall of the pipe body is provided with a hole for passing the valve stem of the valve, a sealing block is installed in the hole, and the valve stem and the pipe body are sealed by the sealing block.

[0023] The provision of the sealing block ensures the sealing between the valve stem and the pipeline body, thereby preventing leakage and maintaining system pressure; protects the valve stem and pipeline from the invasion of external impurities, thereby reducing friction and wear between the valve stem and the pipeline; and facilitates installation and maintenance.

[0024] Optionally, the nozzle has an expansion structure, and the expansion end of the nozzle has a plurality of fine water mist spray holes.

[0025] The flared structure and water mist nozzle arrangement disperse the pressure of liquid passing through the nozzle, reducing pipe wear and leakage risks, extending the service life of the piping system, and lowering equipment maintenance costs. Multiple water mist nozzles are located at the flared end of the nozzle, atomizing water or other liquids into fine particles. This increases the contact area between the water mist and the air, providing more comprehensive coverage of the fire source and improving firefighting efficiency in applications such as firefighting. Furthermore, the multiple nozzles work together to maintain a relatively stable spray effect even when pipe flow fluctuates. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0035] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] like Figure 1 As shown, the utility model provides a high-pressure fine water mist nozzle 3, including a pipe body 1, a pressurized channel 2, a nozzle 3 and a valve; the pipe body 1 has a pressurized channel 2 inside; the nozzle 3 is connected to the pipe body 1 and communicates with the outlet of the pressurized channel 2; the valve is connected to the pipe body 1; the valve has a valve core 4, the valve core 4 extends and is placed in the pressurized channel 2 and can move along the radial direction of the pressurized channel 2 to adjust the flow area of the pressurized channel 2.

[0039] The valve core 4 of the valve of the above-mentioned high-pressure fine water mist nozzle 3 can move along the radial direction of the pressurized channel 2, thereby adjusting the flow area of the pressurized channel 2. In this way, the nozzle 3 can flexibly adjust the pressure and flow of the water mist according to different usage scenarios and needs, achieve precise control, and meet the requirements for fine water mist performance in various situations. After all, different application scenarios usually require different water mist pressures and flows, so the adjustable characteristics of the nozzle 3 enable it to adapt to a variety of environments. In the field of fire protection, whether it is responding to building fires, forest fires or industrial equipment fires, the nozzle 3 can adapt to different fires and fire-fighting needs by adjusting the flow area, thereby improving fire-fighting efficiency. In addition, the nozzle 3 is tightly connected to the pipe body 1, and the internal pressurized channel 2 can ensure that the water mist is fully pressurized before being sprayed, thereby ensuring the spray distance and coverage range of the water mist. At the same time, the design of the valve can stably control the flow area of the pressurized channel 2, avoiding the situation where the sprayed water mist is unstable due to pressure fluctuations. This stable performance can improve the reliability and service life of the nozzle 3, reduce maintenance costs, and continuously provide users with efficient fine water mist fire extinguishing services during long-term use. In addition, the structure of the high-pressure fine water mist nozzle 3 is relatively simple, making it easier to manufacture and install, thereby reducing production costs.

[0040] like Figure 2 As shown, in some embodiments of the present invention, a filter plate 5 is provided in the pipeline body 1, and the filter plate 5 is arranged upstream of the valve.

[0041] Specifically, by arranging the filter plate 5 upstream of the valve, impurities can be prevented from damaging the valve, thereby extending the service life of the valve; the valve operation can be kept smooth, and the accumulation of impurities can avoid increased operating resistance or even jamming of the valve; the number of maintenance times can be reduced, the probability of failures caused by impurities can be reduced, and maintenance costs and time can be saved; the system operation can be stabilized, and the stability of fluid flow and pressure can be ensured; equipment blockage can be prevented, and the normal operation of downstream equipment can be protected; the performance and life of the equipment can be improved, and a clean fluid environment can be provided for downstream equipment; impurities can be easily cleaned and concentrated on the filter plate 5 for easy cleaning or replacement; maintenance costs can be reduced, and damage to the pipeline system and equipment can be reduced, and the cost of cleaning and replacing the filter plate 5 is low.

[0042] Of course, the above description is not restrictive, and in some alternative embodiments, the filter plate 5 can be omitted.

[0043] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the inlet section of the pressurized channel 2 has a flared structure, and the filter plate 5 is installed on the inlet section.

[0044] Specifically, by setting a flared structure at the inlet section of the pressurized channel 2, a larger installation space is provided to facilitate the installation of a filter plate 5 with a larger area, thereby increasing the filtration area and improving the filtration efficiency. It can also reduce the fluid flow rate, allowing impurities more time to contact the filter plate 5, thereby improving the filtration effect; it can make the fluid transition smoothly when entering the pressurized channel 2, reduce turbulence and eddy currents, reduce pressure loss, improve system energy efficiency, and avoid damage to pipelines and equipment caused by excessive local pressure; it provides a more spacious space, facilitates the installation of the filter plate 5, and improves installation efficiency; it also makes maintenance and replacement of the filter plate 5 more convenient, reducing maintenance time and cost; it can effectively intercept impurities in the fluid, reduce the impact on the pressurized channel 2 and downstream equipment, improve system stability and reliability, and combined with the filter plate 5 can reduce the risk of blockage, ensuring the continuous operation of the system.

[0045] like Figure 3 As shown, in some embodiments of the present invention, the valve further includes a valve stem 6 and a valve seat 7. The valve seat 7 is detachably mounted on the pipeline body 1. The valve stem 6 is threadedly connected to the valve seat 7. The end of the valve stem 6 is connected to the valve core 4.

[0046] Specifically, the precise adjustment of the position of the valve core 4 is achieved by threading the valve stem 6 and the valve seat 7. By rotating the valve stem 6, the movement distance of the valve core 4 can be controlled with a smaller angle change, thereby accurately adjusting the flow rate of the nozzle. At the same time, the operator can control the opening and closing of the valve and the flow rate adjustment by manually rotating the valve stem 6, which is simple and intuitive to operate. Furthermore, when the valve seat 7 is worn, corroded or otherwise damaged, it can be removed from the pipeline body 1 for repair or replacement without replacing the entire valve, which reduces maintenance costs and time. In addition, the detachable valve seat 7 can be selected from different materials and types of valve seats 7 according to different working conditions and fluid characteristics, thereby improving the versatility of the valve.

[0047] like Figure 3 As shown, in some embodiments of the present invention, the valve stem 6 and the valve core 4 are connected via a bearing.

[0048] Specifically, the provision of bearings within the valve core 4 can reduce the coefficient of friction between the valve stem 6 and the valve core 4, lower the operating torque, reduce the labor intensity of the operator, reduce the wear of the valve stem 6 and the valve core 4, and increase the service life of the valve core 4. The bearings can provide stable motion support, make relative motion more precise, eliminate possible jamming or jitter between the valve stem 6 and the valve core 4, and make the valve movement smoother. Specially designed bearings can operate under harsh working conditions, allowing the connection to remain reliable under extreme conditions. The corrosion-resistant bearing material can improve the corrosion resistance of valves operating in corrosive media. In the event of a bearing failure, it can be replaced individually, reducing maintenance costs and repair time. The bearing structure is simple and easy to maintain. Daily inspections, lubrication, and other operations can be performed to ensure normal operation.

[0049] like Figure 3 As shown, in some embodiments of the present invention, the valve further includes a handle 8 , which is connected to the top end of the valve stem 6 and is used to drive the valve stem 6 to rotate.

[0050] Specifically, the addition of a handle 8 to rotate the valve stem 6 improves operational convenience. Handle 8 provides the operator with an intuitive, easy-to-grip component. Turning handle 8 effortlessly rotates the valve stem 6, making valve opening and closing simpler and more direct, without the need for tools or effort. Handle 8 increases torque, making valve operation more labor-efficient, a significant advantage during frequent operation or when operating large valves with significant resistance. Handle 8 allows the operator to more precisely control the rotation angle of the valve stem 6, providing a clearer sense of rotation and accurate adjustment of the valve opening to meet varying flow control requirements.

[0051] like Figure 3 As shown, in some embodiments of the present invention, the valve seat 7 is annular and is surrounded and connected to the pipeline body 1.

[0052] Specifically, the annular valve seat 7 tightly surrounds the pipe body 1. This connection ensures that the forces acting on the valve seat 7 are evenly distributed around the pipe. This reduces localized stress concentrations and significantly reduces the risk of damage. Compared to traditional single-sided or point-type connections, the surround connection provides a larger contact area, making the connection more secure and reliable. It can withstand greater tension, torsional force, and vibration, ensuring stable performance in a variety of complex operating environments. The annular valve seat 7 forms a complete annular sealing surface with the pipe body 1, effectively preventing fluid leakage and improving sealing reliability. This ensures system sealing even under harsh conditions such as high pressure and low temperature, avoiding resource waste and safety hazards caused by leakage. Furthermore, the design of the annular valve seat 7 is extremely simple. Installation requires no complex tools or specialized techniques, and can be easily completed by ordinary operators, saving significant time and costs. In the event of a malfunction, it can be removed directly from the pipe for inspection or replacement, with minimal impact on the entire pipe system. This not only reduces the difficulty and time cost of maintenance, but also ensures the continuous and stable operation of the system.

[0053] like Figure 4 As shown, in some embodiments of the present invention, the outer surface of the valve seat 7 has a mounting plane, and the mounting plane has a threaded hole for passing the valve stem 6.

[0054] Specifically, the flat mounting surface on the valve seat 7 provides a stable foundation for valve installation. The large contact area between the flat surface and the mounting area effectively distributes pressure, ensuring that the valve does not wobble or shift during operation due to uneven force. This improves the overall stability of the valve and ensures its proper operation. The flat mounting surface provides a clear reference during installation, allowing installers to more accurately position the valve. The flat mounting surface allows for easy determination of the valve's installation direction and position, reducing installation errors and improving installation efficiency. The threaded hole and valve stem 6 cooperate to precisely control the position of the valve stem 6. By rotating the valve stem 6, the threads allow precise axial movement of the valve stem 6, accurately adjusting the valve opening. The rotation of the valve stem 6 allows for fine adjustment of fluid flow according to actual needs. Threaded connections offer high reliability and sealing properties. The threaded fit between the threaded hole and valve stem 6 creates a tight connection, preventing fluid leakage. Even in harsh operating environments such as high pressure or high temperature, threaded connections ensure valve sealing and safe system operation. If the valve needs to be maintained or parts such as the valve stem 6 need to be replaced, the threaded connection design makes disassembly and installation more convenient. The valve stem 6 can be easily unscrewed from the threaded hole for maintenance or replacement, and then reinstalled, which reduces maintenance costs and time.

[0055] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the outer wall of the pipe body 1 has a hole for passing the valve stem 6 of the valve, and a sealing block 9 is installed in the hole. The valve stem 6 and the pipe body 1 are sealed by the sealing block 9.

[0056] Specifically, the sealing block 9 ensures the sealing between the valve stem 6 and the pipeline body 1 to prevent fluid leakage. Leakage will cause waste of resources, environmental pollution and even safety accidents. The sealing block 9 can prevent pressure leakage, maintain the stability of the pipeline system pressure, ensure that the system operates within the required pressure range, and improve reliability and efficiency. It can also prevent external dust, impurities and moisture from entering the interior of the pipeline, protect the valve stem 6 and the pipeline from corrosion damage, extend the service life of the valve and pipeline, and reduce maintenance costs. The sealing block 9 can reduce the friction and wear between the valve stem 6 and the pipeline, play a lubricating and buffering role, and make the valve operation smoother. The sealing block 9 is easy to install and can be quickly installed in the hole of the pipeline body 1 without the need for complex tools and techniques, thereby improving installation efficiency. If the sealing block 9 is damaged or aged, it can be easily replaced without the need for large-scale disassembly and maintenance of the valve or pipeline, reducing downtime and maintenance costs.

[0057] like Figure 5 As shown, in some embodiments of the present invention, the nozzle 3 has an expansion structure, and the expansion end of the nozzle 3 has a plurality of fine water mist spray holes 10.

[0058] Specifically, by providing a flared structure in the nozzle 3, the pressure of the liquid when passing through the nozzle 3 can be dispersed. In practical applications, this can reduce the wear and leakage risks of the pipeline, extend the service life of the pipeline system, and also reduce the maintenance cost of the equipment. By providing a plurality of fine water mist nozzle holes 10 at the flared end of the nozzle 3, the fine water mist nozzle holes 10 can atomize water or other liquids into very fine particles, increasing the contact area between the water mist and the air, which enables the water mist to evaporate, absorb heat or combine with pollutants in the air more quickly. For example, in firefighting applications, it can cover the fire source area more comprehensively and improve the fire extinguishing efficiency. In addition, the combined effect of the multiple nozzle holes 10 enables a relatively stable spray effect to be maintained even when the pipeline flow fluctuates.

[0059] Working principle:

[0060] When the sprinkler 3 is used in a fire scene, the user connects the external pipe to the device through the thread of the pipe inlet section to supply water to the device. The filter plate 5 at the front end of the pipe inlet section is clamped inside it. Water flows into the interior of the pressurized pipe from the filter holes opened on the surface of the filter plate 5. The filter plate 5 can filter the water to prevent fine particles from entering the interior of the pipe and clogging the pipe. The filter plate 5 is clamped inside the inlet section, which is convenient for the user to remove the filter plate 5 for cleaning and replacement. The interior of the inlet section is designed to be large at the front and small at the back, tightly connected to the pressurized channel 2. Water flows from the large pipe into the small pipe, thereby pressurizing the water body. The user can turn the handle 8 to make the valve stem 6 of the valve rotate up and down inside the pipe under the constraint of the valve seat 7 and the sealing block 9, and the valve core 4 of the valve is adapted to the inner wall of the pressurized channel 2. The handle 8 drives the valve core 4 to move up and down to block the flow area of water passing through the pressurized channel 2, thereby flexibly adjusting the water output flow of the sprinkler 3. Because the nozzle 3 is threadedly connected to the outlet section of the pipe body 1, the nozzle 3 can be manually disassembled for cleaning and maintenance, which is also convenient for daily maintenance. To ensure the stable operation of the nozzle 3, the water source valve is first opened to pressurize the water entering the nozzle 3. The pressurized high-pressure water flow is ejected from the spray hole 10 opened in the outlet section of the water spray plate in the form of a fine water mist. At this time, the high-pressure fine water mist can quickly vaporize, absorb a large amount of heat, and effectively reduce the temperature and humidity of the environment. Since the generated high-pressure fine water mist particles are small, it can well cover the fire area and improve the fire extinguishing efficiency. After the fire is extinguished, the water source valve can be closed and the nozzle 3 can be disassembled for cleaning and maintenance. The nozzle 3 is rationally designed and can provide stable and reliable high-pressure fine water mist to ensure the safe and reliable implementation of fire extinguishing work. The nozzle 3 has precise flow control capabilities and is also applicable when responding to fire extinguishing needs of different areas and fire sizes. In addition, for different application scenarios, such as industrial humidification, agricultural irrigation, and environmental dust removal, the flow rate can also be adjusted according to specific needs to achieve the best fire extinguishing, humidification, or irrigation effects.

[0061] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
