Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, and in particular to a flow-stabilizing blade type fan nozzle. Background Technology

[0002] In existing technologies, nozzles are a crucial component in many spraying, misting, oil spraying, sandblasting, and coating equipment, playing a vital role. Nozzles have a wide range of applications across industries, using materials ranging from stainless steel and plastics to silicon carbide, polytetrafluoroethylene (PTFE), PP engineering plastics, aluminum alloys, and tungsten steel. They are commonly used in various industries including automotive, electroplating, surface treatment, high-pressure cleaning, dust removal, cooling, desulfurization, humidification, mixing, and landscaping.

[0003] Traditional fan-shaped nozzles have a spherical slit nozzle tip. When liquid hits the nozzle, it reflects off the spherical surface and collides with the liquid in the forward nozzle tip, causing turbulence and deviation of the direct liquid, resulting in unevenness and bifurcation. Utility Model Content

[0004] In order to overcome the shortcomings of traditional fan-shaped nozzles, where the spherical slit nozzle head causes the ejected liquid to collide with the forward liquid after being reflected by the spherical surface, resulting in turbulence and deviation of the angle of the direct liquid, leading to uneven atomization and spray bifurcation, this utility model provides a flow-stabilizing blade type fan-shaped nozzle.

[0005] A flow-stabilizing blade type fan-shaped nozzle includes a nozzle body, a flow-stabilizing blade, and a nozzle head. The nozzle body has a through-type fluid channel along the axial direction. The flow-stabilizing blade is provided on the upper part of the inner wall of the fluid channel, and the nozzle head is provided on the lower part of the inner wall of the fluid channel. A spray chamber is formed inside the nozzle head and is connected to the fluid channel. A water outlet hole is provided at the end of the spray chamber.

[0006] As a further preferred option, the top edge of the nozzle head is seamlessly connected to the lower part of the flow stabilizer blade to form a continuous and unobstructed flow channel.

[0007] As a further preferred embodiment, the water outlet is a V-shaped groove, and the groove angle is adapted to the preset coverage angle of the fan-shaped jet.

[0008] As a further preferred embodiment, the flow-stabilizing blade is fixed with an interference fit to the inner wall of the fluid channel.

[0009] As a further preferred option, the nozzle head is made of tungsten steel.

[0010] As a further preferred embodiment, the inner wall of the fluid channel is polished.

[0011] The beneficial effects of this utility model are as follows: This utility model divides the liquid flow into two symmetrical and orderly streams through the flow stabilizing blades. The liquid flow, after being regulated by the flow stabilizing blades, is ejected after being guided by the injection chamber, avoiding the bifurcation phenomenon and forming a fan-shaped jet with a regular outline and uniform distribution.

[0018] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0019] A type of flow-stabilizing blade fan-shaped nozzle, such as Figures 1-5As shown, the device includes a nozzle body 1, a flow-stabilizing blade 2, and a nozzle head 3. The nozzle body 1 has an axially continuous fluid channel 11 inside. The inner wall of the fluid channel 11 is polished to reduce flow resistance and ensure smooth flow. A flow-stabilizing blade 2 is located on the upper part of the inner wall of the fluid channel 11, and is fixed to the inner wall of the fluid channel 11 with an interference fit. This interference fit ensures a firm fixation between the flow-stabilizing blade 2 and the inner wall of the fluid channel 11, preventing displacement of the flow-stabilizing blade 2 due to fluid impact and ensuring a stable flow effect. A nozzle head 3 is located on the lower part of the inner wall of the fluid channel 11. The nozzle head 3 uses... Made of tungsten steel, the nozzle head 3 exhibits enhanced wear and erosion resistance, extending its service life under high-pressure fluid jetting conditions. An internal jetting chamber 31 is formed within the nozzle head 3, connected to the fluid channel 11. A water outlet 32 ​​is located at the end of the jetting chamber 31. The top edge of the nozzle head 3 seamlessly connects to the lower part of the flow stabilizer blade 2, forming a continuous and unobstructed flow channel. This reduces local resistance during the flow process, ensuring a smooth and stable entry of the liquid into the jetting chamber 31. The water outlet 32 ​​is a V-shaped groove, with the groove angle matching the preset coverage angle of the fan-shaped jet, ensuring a regular fan-shaped jet profile.

[0020] After the liquid enters through the fluid channel 11 of the nozzle body 1, it first flows through the flow stabilizing blade 2 at the top of the fluid channel 11. The flow stabilizing blade 2 divides the originally turbulent liquid into two symmetrical and orderly liquid flows, while eliminating the internal eddies and turbulence of the fluid, thus achieving rectification and stabilization. Then, the regulated liquid flow smoothly enters the injection chamber 31. After being guided and converged by the nozzle head 3, it is finally ejected through the water outlet 32, forming a fan-shaped jet with a regular profile and uniform distribution.

[0021] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
