Description

Technical Field

[0001] This utility model relates to the field of nozzle equipment technology, specifically a high-pressure water atomizing nozzle. Background Technology

[0002] A high-pressure water atomizing nozzle is an industrial component that uses a high-pressure pump to pressurize water or water-containing media to a high pressure. When the medium passes through the nozzle outlet with a specific structure, the pressure energy is converted into kinetic energy, and it violently collides and shears with the surrounding air or target medium, thus breaking it into tiny droplets and forming a uniform and dispersed atomized spray. Its core function is to achieve efficient atomization of liquids through pressure drive. It is widely used in industrial and environmental protection scenarios such as cooling, humidification, dust removal, cleaning, and combustion assistance. The internal flow channel design of the nozzle directly determines key performance parameters such as atomized particle size, spray angle, and flow distribution.

[0003] Existing Chinese patent document CN201832313U discloses a high-pressure fine water atomizing nozzle, comprising a main body with an inner cavity, and an insert, a swirling core, a clamping washer, and a rimmed filter screen sequentially arranged within the inner cavity of the main body. The swirling core has swirling grooves on its side to rotate high-pressure, high-speed water. The insert has nozzles for spraying out the turbulent, rotating water within the inner cavity. It requires a small spray flow rate, saves water resources, and produces small atomized particles; at 10 MPa pressure, D(V, 0.9) < 80 μm. Its compact structure, small size, and low manufacturing cost make it a safe, energy-saving, and environmentally friendly green disaster prevention technology. However, this high-pressure water atomizing nozzle still has shortcomings: its dynamic pressure adaptability is insufficient, the relative position of its swirl core and insert is fixed, and atomization is achieved only by the fixed structure of the swirl groove and the nozzle. When the pressure of the water supply pipeline fluctuates, the water flow rotation intensity and the spray direction are prone to deviation, resulting in unstable spray angle and reduced uniformity of atomized particle size, making it difficult to meet the requirements for atomization consistency under high-pressure dynamic working conditions. Utility Model Content

[0004] The purpose of this invention is to address the problem that the dynamic pressure adaptability of the aforementioned high-pressure water atomizing nozzles is insufficient, the relative position of the swirl core and insert is fixed, and atomization is achieved solely by the fixed structure of the swirl groove and the nozzle orifice. When the pressure of the water supply pipeline fluctuates, the water flow rotation intensity and the spray direction are prone to deviation, resulting in unstable spray angle and decreased uniformity of atomized particle size, making it difficult to meet the requirements for atomization consistency under high-pressure dynamic conditions. Therefore, this invention provides a high-pressure water atomizing nozzle.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-pressure water atomizing nozzle, comprising: a nozzle connecting cylinder, an extension cylinder fixedly connected to one end of the nozzle connecting cylinder, an adaptive pressure plate tightly attached to one side of the nozzle connecting cylinder, an adaptive pressure ring fixedly sleeved on the outside of the adaptive pressure plate, and a filter cylinder internally engaged at the other end of the nozzle connecting cylinder, wherein a plurality of filter holes are provided through the bottom of the filter cylinder. A connecting spring is fixed to the side of the adaptive pressure ring that is in contact with the nozzle connecting cylinder. A spring groove is provided on this side of the nozzle connecting cylinder. A conical block is fixed to the center of the same side of the adaptive pressure plate to achieve an elastic connection between the adaptive pressure ring and the nozzle connecting cylinder. The nozzle connecting cylinder has a through groove on one side where the filter cylinder is engaged. A through block is movably inserted inside the through groove. A limit plate is fixed to the end face of the through block. Tension springs are fixed to both ends of the inner side of the limit plate to stably press the filter cylinder into the nozzle connecting cylinder.

[0006] As a further improvement of this utility model: the number of connecting springs is set to four sets, which are symmetrically arranged in four directions on the adaptive pressure ring; the number of spring grooves is set to four sets, which are symmetrically arranged in four directions on the opposite side of the nozzle connecting cylinder; and the other end of each connecting spring is fixed to the inside of the spring groove.

[0007] As a further embodiment of this utility model: the adaptive pressure ring has a plurality of sets of liquid outlet holes, the outer side of the adaptive pressure ring is symmetrically fixed with guide sliders in four directions, the inner side of the extension cylinder is symmetrically provided with guide grooves in four directions, and the number and specifications of the guide sliders and guide grooves are compatible.

[0008] As a further improvement of this utility model: the contact surface specifications of the adaptive pressure plate and the conical block fixed to its side are compatible, and a top block is fixed to the tip of the conical block. The outer side of the top block abuts against the center of the inner side of the filter cylinder to improve the stability of the filter surface in the filter cylinder.

[0009] As a further embodiment of this utility model: two sets of the through groove, through block and limiting plate are provided, symmetrically arranged at both ends of the nozzle connecting cylinder. After the side of the through block is inserted into the through groove, it abuts against the filter cylinder to fix its stable state. Tension springs are fixedly connected to both ends of the inner side of the two sets of limiting plates, and the other end of the tension springs is fixedly connected to the corresponding position on the outside of the nozzle connecting cylinder.

[0010] As a further improvement of this utility model: the inner side of the nozzle connecting cylinder used for installation is provided with an installation thread, and the outer side of the end of the nozzle connecting cylinder that needs to be connected to the water pipe is provided with a thread structure that matches its specifications.

[0011] As a further embodiment of this utility model: the nozzle connecting cylinder and the extension cylinder are fixedly connected to each other, an expansion ring is fixedly connected to the other end face of the extension cylinder away from the nozzle connecting cylinder, and a filter cylinder handle is fixedly connected to the outward side of the filter cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model constructs a dual guarantee mechanism of pressure self-adaptation and water leakage prevention through the coordinated design of four sets of symmetrical connecting springs, guide sliders, and guide grooves. On the one hand, the four sets of cross-shaped symmetrical connecting springs are elastically connected to the spring grooves of the nozzle connecting cylinder. When the high-pressure water flow impacts the adaptive pressure ring, the springs deform synchronously to keep the pressure ring parallel to the connecting cylinder, avoiding the skewing caused by uneven force. The guide slider on the outside of the adaptive pressure ring and the guide groove on the inside of the extension cylinder form a clearance fit, strictly limiting the pressure ring to only translate along the axial direction, eliminating the influence of rotation or sway on the spray direction of the water outlet. On the other hand, the adaptive pressure plate and the matching conical structure of the conical block can accurately guide the water flow to the water outlet, ensuring that multiple jets stably converge and collide in the extension cylinder. The elastic connection structure opens to different degrees according to the water pressure, realizing adaptive opening. 2. This utility model achieves a deep integration of filtration function and convenient maintenance through the integrated design of the filter cartridge, the through-block, the tension spring, and the filter cartridge handle. Firstly, the filter cartridge is built-in through a snap-fit ​​mechanism, and two sets of symmetrical through-blocks are inserted into the through-slots under the action of the tension spring, abutting against the filter cartridge to achieve stable fixation. At the same time, the hard alloy top block at the tip of the conical block presses against the center of the filter cartridge, suppressing radial vibration under high pressure and preventing the filter hole from shifting and affecting the filtration effect. Impurities can be intercepted without the need for additional filter components. Secondly, the U-shaped filter cartridge handle on the outside of the filter cartridge, together with the through-block that can be quickly pulled out, allows a single person to replace the filter cartridge in seconds without tools.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0017] Reference Figures 1 to 5In this embodiment of the present invention, a high-pressure water atomizing nozzle includes: a nozzle connecting cylinder 1, an extension cylinder 8 fixedly connected to one end of the nozzle connecting cylinder 1, an adaptive pressure plate 2 tightly attached to one side of the nozzle connecting cylinder 1, an adaptive pressure ring 3 fixedly sleeved on the outside of the adaptive pressure plate 2, a filter cylinder 11 engaged inside the other end of the nozzle connecting cylinder 1, and a plurality of filter holes 12 penetrating through the bottom of the filter cylinder 11; a connecting spring 4 fixedly connected to the side of the adaptive pressure ring 3 that is in contact with the nozzle connecting cylinder 1, a spring groove 5 opened on this side of the nozzle connecting cylinder 1, and a conical block 6 fixedly connected to the center of the adaptive pressure plate 2 on the same side to achieve an elastic connection between the adaptive pressure ring 3 and the nozzle connecting cylinder 1; a through groove 13 penetrating through the side of the nozzle connecting cylinder 1 where the filter cylinder 11 is engaged, a through block 14 movably passing through the through groove 13, a limiting plate 15 fixedly connected to the end face of the through block 14, and tension springs 16 fixedly connected to both ends of the inner side of the limiting plate 15 to stably press the filter cylinder 11 into the nozzle connecting cylinder 1.

[0018] Reference Figure 2 There are four sets of connecting springs 4, which are symmetrically arranged in four directions on the adaptive pressure ring 3. There are four sets of spring grooves 5, which are symmetrically arranged in four directions on the opposite side of the nozzle connecting cylinder 1. The other end of each connecting spring 4 is fixed to the inside of the spring groove 5.

[0019] The above scheme employs a cross-shaped symmetrical distribution of four sets of connecting springs 4 at the four positions of the adaptive pressure ring 3. The diameter, length, and elastic coefficient of each set of connecting springs 4 are consistent, ensuring that the adaptive pressure ring 3 is subjected to a balanced elastic tension. The depth of the spring groove 5 is slightly greater than the free length of the connecting spring 4, and the edge of the groove is rounded to prevent the connecting spring 4 from being scratched by the edge of the spring groove 5 of the nozzle connecting cylinder 1 when it extends or retracts. The advantage of this symmetrical layout is that when the high-pressure water flow impacts and causes the adaptive pressure ring 3 to spring open, the four sets of connecting springs 4 deform synchronously, keeping the adaptive pressure ring 3 parallel to the nozzle connecting cylinder 1 at all times. This prevents skewing caused by uneven force, thereby ensuring the stability of the spray angle. At the same time, the constraint effect of the spring groove 5 on the connecting spring 4 can prevent the connecting spring 4 from lateral swaying under high pressure, extending its fatigue life.

[0020] Reference Figure 2 and Figure 5 The adaptive pressure ring 3 has several sets of liquid outlet holes. The outer side of the adaptive pressure ring 3 is symmetrically fixed with guide sliders 7 in four directions. The inner side of the extension cylinder 8 is symmetrically provided with guide grooves 9 in four directions. The number and specifications of the guide sliders 7 and guide grooves 9 are matched.

[0021] The above scheme employs a ring-shaped arrangement of water outlet holes on the adaptive pressure ring 3, with the hole axis at a certain angle to the plane of the adaptive pressure ring 3. This ensures that the sprayed water flow can form initial convergence and atomization within the extension cylinder 8. The guide slider 7 and the guide groove 9 on the inner side of the extension cylinder 8 form a clearance fit. The core advantage of this structure is that the fit between the guide slider 7 and the guide groove 9 restricts the movement trajectory of the adaptive pressure ring 3, allowing it to only translate axially without rotating or swaying. This ensures that the spray direction of the water outlet holes on the adaptive pressure ring 3 remains consistent. At the same time, the hemispherical end of the guide slider 7 reduces sliding friction resistance, making the adaptive pressure ring 3 more sensitive to changes in water pressure and achieving stable atomization under dynamic pressure.

[0022] Reference Figure 2 The adaptive pressure plate 2 and the conical block 6 fixed to its side are compatible in terms of contact surface specifications. A top block 10 is fixed to the tip of the conical block 6. The outer side of the top block 10 abuts against the center of the inner side of the filter cylinder 11 to improve the stability of the filter surface in the filter cylinder 11.

[0023] The above scheme is adopted: the adaptive pressure plate 2 and the conical block 6 are fixedly connected to each other, the top block 10 is cylindrical and made of hard alloy, and it abuts against the filter cylinder 11. The functional value of this design is reflected in the fact that the conical block 6 guides the water flow to spray out along the outlet hole of the conical guide adaptive pressure ring 3. The high wear resistance of the hard alloy top block 10 can avoid wear caused by long-term contact, and at the same time reduce the pressure damage to the inner mesh surface of the filter cylinder 11. It abuts against the center of the filter cylinder 11 to extend the replacement cycle of the filter cylinder 11.

[0024] Reference Figure 3 and Figure 4 Two sets of slots 13, blocks 14 and limiting plates 15 are provided, symmetrically arranged at both ends of the nozzle connecting cylinder 1. After the side of the block 14 is inserted into the slot 13, it abuts against the filter cylinder 11 to fix its stable state. Tension springs 16 are fixed to both ends of the inner side of the two sets of limiting plates 15, and the other end of the tension springs 16 is fixed to the corresponding position on the outside of the nozzle connecting cylinder 1.

[0025] The above scheme is adopted: the through slot 13 is a long strip-shaped through hole opened on the nozzle connecting cylinder 1, and the through block 14 is a matching cuboid. The insertion end is chamfered to facilitate installation into the through slot 13. The tension spring 16 can keep the through block 14 in an inwardly pressed state in the natural state. The core function of this structure is to lock the relative position of the adaptive pressure ring 3 and the adaptive pressure plate 2 through the rigid contact between the through block 14 and the adaptive pressure plate 2. It is suitable for working conditions that require fixed atomization parameters. When adjustment is required, the through block 14 can be pulled out by simply pulling the limiting plate 15 outward. The switching can be completed without tools. The symmetrical arrangement of the two sets of through slots 13, through blocks 14 and limiting plates 15 can ensure that the filter cylinder 11 is subjected to balanced force, while the continuous force of the tension spring 16 can prevent the through block 14 from loosening under high pressure conditions, ensuring the reliability of the locked state.

[0026] Reference Figure 3 The nozzle connecting cylinder 1 has an installation thread 17 on the inner side of one end for installation, and a thread structure that matches its specifications is provided on the outer side of the end of the nozzle connecting cylinder 1 that needs to be connected to the water pipe.

[0027] The above solution is adopted: the mounting thread 17 on the nozzle connecting sleeve 1 and the water pipe connection end of the nozzle connecting sleeve 1 both adopt fine thread. The fine thread 17 has higher connection strength and anti-loosening performance, which is suitable for fixing high pressure equipment. The combination of pipe thread and sealing groove can achieve double sealing and no leakage under high pressure. The standardized thread specification ensures the compatibility of nozzle connecting sleeve 1 with different equipment and reduces replacement and maintenance costs.

[0028] Reference Figure 3 and Figure 5 The nozzle connecting tube 1 and the extension tube 8 are fixedly connected to each other. An expansion ring 18 is fixedly connected to the other end face of the extension tube 8 away from the nozzle connecting tube 1. A filter tube handle 19 is fixedly connected to the outward side of the filter tube 11.

[0029] The above scheme is adopted: the extension tube 8 and the nozzle connecting tube 1 are fixed by welding. The inner diameter of the extension tube 8 and the nozzle connecting tube 1 form a gradually expanding flow channel. The expansion ring 18 is a trumpet-shaped structure fixed to the extension tube 8 with rounded edges. The filter cartridge handle 19 is a U-shaped structure and is integrally injection molded with the filter cartridge 11. The functional benefits of this design include that the gradually expanding flow channel of the extension tube 8 can reduce the water flow velocity and reduce turbulence noise. The expansion ring 18 can further expand the spray range. The U-shaped filter cartridge handle 19 provides a convenient force point for disassembling and assembling the filter cartridge 11. The replacement operation can be completed by a single person. Moreover, the integrated design of the filter cartridge handle 19 and the filter cartridge 11 avoids the risk of falling off.

[0030] The working principle of this utility model is as follows: First, the nozzle is installed on the water inlet foundation. The nozzle is fixedly installed with the equipment through the mounting thread 17 on the inner side of the nozzle connecting cylinder 1. The outer thread structure of its water pipe connection end is adapted to the specification of the mounting thread 17, so it is sealed to the water supply pipeline. The sealing ring groove at the beginning of the thread cooperates with the O-ring rubber ring to form a double seal, ensuring no leakage when the high-pressure water flow is delivered. At this time, the filter cylinder 11 is assembled inside the other end of the nozzle connecting cylinder 1 by a snap-fit ​​method. Two sets of symmetrically arranged through slots 13, through blocks 14 and limiting plates 15 cooperate. Under the continuous tension of the tension spring 16, the through blocks 14 are inserted into the through slots 13 and abut against the filter cylinder 11, so that the filter cylinder 11 is stably pressed into the nozzle connecting cylinder 1. At the same time, the top block 10 of the cone block 6 fixed to the side of the self-adaptive pressure plate 2 abuts against the inner center of the filter cylinder 11, further suppressing the radial vibration of the filter cylinder 11 under the impact of high-pressure water flow, avoiding the filter hole 12 from being affected by vibration displacement and affecting the filtration effect, realizing the initial filtration of impurities in the incoming water and preventing subsequent structural blockage. Next, the pressure adaptive adjustment and water flow guidance process begins. The high-pressure water flow, filtered through the filter hole 12, acts on the adaptive pressure plate 2, which is tightly attached to the nozzle connecting cylinder 1. The adaptive pressure ring 3, which is fixedly sleeved on the outside of the adaptive pressure plate 2, is elastically connected to the spring groove 5 of the nozzle connecting cylinder 1 through four sets of cross-shaped symmetrically distributed connecting springs 4. The depth of the spring groove 5 is slightly greater than the free length of the connecting spring 4, which provides the connecting spring 4 with the space for expansion and contraction, and prevents it from swinging laterally. The rounded corners of the groove prevent the spring from being scratched. When the high-pressure water flow impacts the adaptive pressure ring 3, the four sets of connecting springs 4 deform synchronously, so that the adaptive pressure ring 3 always remains parallel to the nozzle connecting cylinder 1, avoiding uneven force that could cause skewing. At the same time, the guide slider 7, which is symmetrically fixed on the outside of the adaptive pressure ring 3, forms a clearance fit with the guide groove 9 on the inside of the extension cylinder 8 fixed to one end of the nozzle connecting cylinder 1, which strictly limits the adaptive pressure ring 3 to only move axially, ensuring that the spray direction of its through-hole ring is stable, laying the foundation for subsequent uniform atomization. The next step is atomization and flow channel optimization. Under the balance of the thrust of the adaptive pressure plate 2 and the tension of the connecting spring 4, the water flow is guided along the matching conical surface of the adaptive pressure plate 2 and the conical block 6, and flows precisely to the water outlet of the adaptive pressure ring 3. When the water flows through the water outlet, due to the flow restriction and tilt design of the channel, multiple high-speed jets are formed inside the extension tube 8. The jets converge and collide with each other to complete the initial atomization. The gradually expanding flow channel of the extension tube 8 can reduce the water flow velocity, reduce turbulence noise, and at the same time provide sufficient space for the jet convergence to optimize the atomization uniformity. Finally, the spray diffusion and structural maintenance convenience are ensured. After initial atomization, the water mist flows along the extension tube 8 to its end and contacts the fixed trumpet-shaped expansion ring 18. The expansion ring 18 further diffuses the water mist range to meet the spray coverage requirements of different scenarios. When the filter cartridge 11 needs to be replaced, simply pull the limiting plate 15 outward to overcome the tension of the tension spring 16 and pull out the through block 14. The filter cartridge 11 can be quickly removed through the U-shaped filter cartridge handle 19 on the outside of the filter cartridge 11. The integrated handle design avoids the risk of falling off and ensures convenient maintenance in the later stage.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
