Description

Technical Field

[0001] The invention relates to the technical field of spray devices, and in particular to a clip-on nozzle with a flow stabilizing structure. Background Art

[0002] In many industrial applications, clip-on nozzles are widely used for precise spraying of liquids. Such nozzles are usually designed to be quickly installed and removed for easy maintenance or replacement. However, in actual use, it was found that existing clip-on nozzles have some problems when conveying liquids, mainly manifested in the turbulence and eddy currents that are easily generated when the liquid passes through the nozzle. These flow instabilities not only affect the quality of liquid spraying, leading to uneven spraying and poor atomization, but also accelerate the wear of the internal materials of the nozzle, thereby reducing the service life of the nozzle.

[0003] One of the main reasons for the above problems is that the liquid is directly compressed after entering the nozzle and sprayed out through a narrow outlet. This process is generally accompanied by large velocity changes and pressure fluctuations, which can easily cause chaos in the flow state. In addition, any non-ideal flow conditions that may exist in the upstream pipeline (such as uneven velocity distribution) will also be transmitted to the nozzle, further exacerbating the instability of the flow.

[0004] In order to improve these problems, the present invention proposes a clip-on nozzle with a flow stabilizing structure. The clip-on nozzle can effectively suppress or even eliminate the occurrence of turbulence and eddy currents, ensuring that the liquid is ejected from the nozzle in a more stable manner. Summary of the invention

[0005] In order to overcome the shortcomings of existing clip-on nozzles when spraying liquid, such as unstable flow, generation of turbulence and eddies leading to nozzle wear, the present invention provides a clip-on nozzle with a flow stabilizing structure. The clip-on nozzle can effectively suppress or even eliminate the occurrence of turbulence and eddies, thereby ensuring that the liquid is sprayed out of the nozzle in a more stable manner.

DETAILED DESCRIPTION

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Embodiment 1: A clip-on nozzle with a steady flow structure, such as Figure 1-Figure 7 As shown, it includes a lower clamping plate 1, an upper clamping plate 2, a rotating push handle 3, a clamping block 4, a flow stabilizing cavity 5, a threaded sleeve 6, a spherical nozzle 7, a first guide body 8, a second guide body 9, an adjustment component and a flow guide component. The lower clamping plate 1 is rotatably connected to the upper clamping plate 2 on the left, and the sides of the lower clamping plate 1 and the upper clamping plate 2 close to each other are fixedly connected with an anti-slip pad. The lower clamping plate 1 is rotatably connected to the rotating push handle 3 on the right, and the clamping block 4 is fixedly connected to the rotating push handle 3. The T-shaped structure of the clamping block 4 is used to lock the lower clamping plate 1 and the upper clamping plate 2. The middle part of the upper clamping plate 2 is fixedly connected with the flow stabilizing cavity 5, and the lower side of the flow stabilizing cavity 5 is fixedly connected with a sealing ring. A threaded sleeve 6 is screwed on the upper part through a thread, and a spherical nozzle 7 is rotatably connected to the upper part of the stabilizing chamber 5. The upper part of the stabilizing chamber 5 is composed of a plurality of elastic petals. The rotation of the threaded sleeve 6 is used to control the elastic petals to close and clamp the spherical nozzle 7. A first guiding body 8 is fixedly connected to the lower part of the stabilizing chamber 5. Two second guiding bodies 9 are fixedly connected in the stabilizing chamber 5. The second guiding bodies 9 are located above the first guiding bodies 8. The guiding holes of the three-layer guiding bodies are staggered. An adjusting component for adjusting the size of the guiding holes of the first guiding body 8 and the second guiding body 9 is provided on the stabilizing chamber 5. A guiding component for guiding the liquid is provided in the stabilizing chamber 5.

[0034] When using the device, the staff controls the lower clamping plate 1 to rotate downward and open, and then covers the upper clamping plate 2 on the water pipe so that the lower side of the flow-stabilizing cavity 5 is aligned with the pre-opened water outlet on the water pipe, so that the flow-stabilizing cavity 5 is connected with the water pipe, and the sealing ring can ensure the sealing effect of the connection between the flow-stabilizing cavity 5 and the water pipe to avoid water leakage. Then the staff controls the lower clamping plate 1 to rotate upward to cooperate with the upper clamping plate 2 to clamp the water pipe, and then pushes the rotating push handle 3 to rotate upward so that the clamping block 4 is clamped on the right part of the lower clamping plate 1 and the upper clamping plate 2, and then the lower clamping plate 1 and the upper clamping plate 2 are locked, and then the device is fixed on the water pipe. When the water pipe After the liquid in the stabilizing flow cavity 5 flows into the stabilizing flow cavity 5, the stabilizing flow cavity 5 acts as a buffer zone, so that the liquid before entering the spherical nozzle 7 can stay in the stabilizing flow cavity 5 for a short time, effectively eliminating any irregular flow pattern from the water pipe, helping to balance the fluid pressure, and the liquid entering the stabilizing flow cavity 5 flows through the first guiding body 8 and the two second guiding bodies 9 in sequence. The fluid channel area is reduced layer by layer through the first guiding body 8 and the second guiding body 9, and the speed and pressure distribution of the fluid are gradually adjusted, which can significantly suppress or even eliminate the occurrence of turbulence and eddy currents, ensuring that the liquid is sprayed out from the spherical nozzle 7 in a more stable manner.

[0035] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the adjustment component includes a rotating ring 10, a connecting frame 11, a vertical rod 12, a first adjusting frame 13 and a second adjusting frame 131. The rotating ring 10 is rotatably connected to the upper part of the stabilizing chamber 5, and the connecting frame 11 is rotatably connected to the upper part of the stabilizing chamber 5. The connecting frame 11 is fixedly connected to the rotating ring 10, and the vertical rod 12 is fixedly connected to the center position of the connecting frame 11. The lower part of the vertical rod 12 is fixedly connected to the first adjusting frame 13, and the first adjusting frame 13 is fitted with the first guide body 8. Two second adjusting frames 131 are fixedly connected to the vertical rod 12, and the second adjusting frames 131 are fitted with the adjacent second guide body 9.

[0036] When using the device, the staff can control the rotation of the rotating ring 10 according to the water pressure in the water pipe. The rotation of the rotating ring 10 drives the connecting frame 11 to rotate. The rotation of the connecting frame 11 drives the vertical rod 12 to rotate. The rotation of the vertical rod 12 drives the first adjustment frame 13 and the second adjustment frame 131 to rotate. After the first adjustment frame 13 and the second adjustment frame 131 rotate, they can block the diversion holes of the first diversion body 8 and the second diversion body 9, thereby reducing the diversion channel. By adjusting the size of the diversion holes of the diversion body according to the change of water pressure, the spherical nozzle 7 can better adapt to the needs under different working conditions, which enables the spherical nozzle 7 to maintain a relatively stable output performance when facing water pressure fluctuations. In addition, when the water pressure is high, the flow velocity can be reduced by increasing the size of the diversion channel, thereby reducing the turbulence caused by high-speed flow; conversely, reducing the channel size under low water pressure conditions can help maintain an appropriate flow velocity and avoid unstable flow states such as vortices. This dynamic adjustment helps to achieve a smoother fluid transmission process.

[0037] like Figure 7 As shown, the flow guide assembly includes a fixed frame 14, a rotating sleeve 15 and spiral blades 16. The fixed frame 14 is fixedly connected to the upper part of the flow stabilizing chamber 5. The rotating sleeve 15 is rotatably connected to the center of the fixed frame 14. Three spiral blades 16 are fixedly connected to the rotating sleeve 15.

[0038] When the device is used, the liquid flows upward in the flow stabilizing chamber 5 and passes through the spiral blades 16, thereby driving the spiral blades 16 to rotate, and the rotating sleeve 15 rotates on the fixed frame 14 accordingly. The rotation of the spiral blades 16 can also guide the liquid, which can help control the direction of the fluid, so that the liquid flows along a predetermined path and enters the spherical nozzle 7 in a more orderly manner.

[0039] Embodiment 2: Based on embodiment 1, Figure 8 and Fig. 9 As shown, it also includes a closing component for preventing impurities from entering the stabilizing flow cavity 5, and the closing component includes a guide sleeve 17, a slide rod 18, an elastic member 181, a block 19 and a push rod 20. The guide sleeve 17 is fixedly connected to the center position of the lower side of the first flow guide body 8, and the slide rod 18 is slidably connected in the guide sleeve 17. The elastic member 181 is connected between the slide rod 18 and the guide sleeve 17. The block 19 is fixedly connected to the lower side of the slide rod 18. The block 19 is made of rubber and is used to block the lower side entrance of the stabilizing flow cavity 5. The push rod 20 is fixedly connected to the lower side of the block 19.

[0040] In the initial state, the blocking block 19 blocks the lower entrance of the stabilizing chamber 5 to prevent dust and impurities from entering the stabilizing chamber 5 before the device is used, thereby affecting the spraying effect of the spherical nozzle 7. When installing the device, the bottom end of the stabilizing chamber 5 is docked with the water outlet of the water pipe, and the push rod 20 is inserted into the water outlet of the water pipe, and then squeezed upward by the water pipe, and the push rod 20 moves upward to drive the blocking block 19 to slide upward, and the blocking block 19 moves upward to drive the sliding rod 18 to slide upward, and the elastic member 181 is deformed. After the blocking block 19 moves upward, it no longer blocks the lower entrance of the stabilizing chamber 5, and the water in the water pipe can enter the stabilizing chamber 5 normally. When the device is used and removed from the water pipe, the push rod 20 is no longer squeezed by the water pipe. At this time, under the action of the resetting of the elastic member 181, the sliding rod 18 drives the blocking block 19 to move downward and reset to block the lower entrance of the stabilizing chamber 5 again.

[0041] like Figure 1 and Fig.10 As shown, it also includes a locking assembly for locking the rotating ring 10, the locking assembly includes a guide frame 21, an extrusion plate 22, a matching plate 23 and a locking ring 24, the guide frame 21 is fixedly connected to the upper right side of the upper clamping plate 2, the extrusion plate 22 is slidably connected to the guide frame 21, the matching plate 23 is fixedly connected to the right side of the extrusion plate 22, the clamping block 4 is rotated upward to be pressed and matched with the matching plate 23, the locking ring 24 is slidably connected to the upper side of the upper clamping plate 2, the side of the extrusion plate 22 close to the locking ring 24 is wedge-shaped, the extrusion plate 22 moves to the left to be pressed and matched with the locking ring 24, a circle of equidistantly distributed protrusions is provided on the outer side of the rotating ring 10, and a circle of grooves matching the protrusions of the rotating ring 10 are opened on the inner side of the locking ring 24.

[0042] When using the device, the clamping block 4 rotates upward to lock the lower clamping plate 1 and the upper clamping plate 2, which will squeeze the matching plate 23 to move to the left. The matching plate 23 moves to the left and drives the extrusion plate 22 to slide to the left. The extrusion plate 22 slides to the left and squeezes the locking ring 24 to slide upward. The locking ring 24 slides upward to cover the rotating ring 10, and then fixes the position of the rotating ring 10 to prevent abnormal rotation of the first adjustment frame 13 and the second adjustment frame 131 after adjustment is completed, affecting the flow stabilization effect.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
