[0002] In modern industry and building systems, valves are widely used in fluid control, gas regulation, and flow and pressure regulation in piping systems. However, during operation, especially under conditions of high fluid velocity and large pressure changes, valves often produce significant noise. This noise is mainly caused by the instability of fluid flow, including turbulence, rapid flow rate changes, and the wake effect of air flow. Especially at the outlet of the valve, after the fluid is adjusted by the valve, the wake noise produced often has high frequency and intensity, becoming one of the main sources of industrial equipment noise pollution.

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Referring to Figures 1-6 , the present application provides an embodiment: a broken tail flow noise reduction device, comprising a barrel 1, a first connecting piece 8 and a second connecting piece 10, an internal thread 3 is formed on one side of the inner wall of the barrel 1, annular teeth 5 are uniformly and interval fixedly connected to the outer side of one side end surface of the barrel 1, windows 6 are uniformly and interval formed on the outer wall of the barrel 1, strip teeth 7 are arranged on both sides of the inside of the plurality of windows 6, the plurality of strip teeth 7 are oppositely arranged between each other, and a cylindrical through hole 12 is formed in the inside of the barrel 1.

[0031] The device effectively shunts and gently adjusts the fluid through the design of the annular teeth 5 of the outlet 4 and the strip teeth 7 of the window 6 of the barrel 1, significantly reduces turbulence and vortex, thereby reducing noise, improving environmental comfort, meeting noise pollution control standards, and creating a quiet and harmonious environment for users.

[0032] The side of the barrel 1 with the internal thread 3 is the inlet 2 of the barrel 1, and the side of the barrel 1 with the annular teeth 5 is the outlet 4 of the barrel 1, which can ensure that the fluid connection between the inlet 2 and the outlet 4 of the barrel 1 is more secure, improving the fluid circulation and the sealing performance of the system. The annular teeth 5 reduce turbulence and turbulence of the fluid or gas inside the barrel 1, thereby reducing noise. The first connecting piece 8 has a first external thread 9 on one side of its outer surface. The first external thread 9 allows the first connecting piece 8 to be more easily connected to the barrel 1 by threading, thereby ensuring a secure connection between the components. The second connecting piece 10 has a second external thread 11 on one side of its outer surface. The second external thread 11 allows the second connecting piece 10 to be more easily connected to the barrel 1 by threading, thereby ensuring a secure connection between the components. The strip teeth 7 gradually increase in thickness from the inside to the outside. The gradually increasing thickness forms a gradually narrowing channel, allowing the fluid or gas to pass through more smoothly and reducing the occurrence of vortex and turbulence. The multiple windows 6 are symmetrically arranged and have multiple numbers. The symmetrical arrangement allows the liquid or gas inside the barrel 1 to move more regularly, which helps to reduce the noise generated by the liquid or gas passing through the device.

[0033] Working principle: When the device is in use, first, the staff needs to select the appropriate first connecting piece 8 or second connecting piece 10 according to whether the upper end of the valve connected is a flange or a thread, and connect it to the upper end of the barrel 1 to ensure that the barrel 1 can be reliably connected to the valve. Then, when the fluid passes through the device, its core noise reduction mechanism begins to work, which is reflected in two aspects: on the one hand, the annular teeth 5 structure at the outlet 4 can effectively shunt the fluid when it flows through the cylindrical through hole 12, allowing the fluid flow to be gently adjusted, significantly reducing the generation of turbulence and vortex, and thereby significantly reducing the noise generated by the liquid, gas, or solid particles passing through the circular hole. On the other hand, the device has multiple windows 6 and strip teeth 7 on its barrel 1 outer wall. When the fluid passes through the barrel 1, these carefully designed strip teeth 7 can effectively shunt the fluid, making the fluid flow more gentle and significantly reducing the vortex and turbulence of the fluid inside the barrel 1. These designs significantly improve the comfort of the surrounding environment, reduce the disturbance of noise to personnel, meet the increasingly stringent noise pollution control standards, and create a quiet and harmonious working or living environment for users.

[0034] It should be pointed out finally that: the above only for the preferred specific embodiments of the present application, and is not used to limit the present application, although the present application is described in detail with reference to the foregoing specific embodiments, for the skilled in the art, it still can be modified to the technical solutions recorded in the foregoing each specific embodiment, or to the equivalent replacement of part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the scope of protection of the present application.
