Description

Technical Field

[0001] This utility model relates to the technical field of pipeline systems for conveying industrial fluids. In particular, this utility model relates to silencers and pipeline systems for use in pipeline systems. Background Technology

[0002] This section provides background information relevant to this application, which does not necessarily constitute prior art.

[0003] Piping systems used to transport industrial fluids typically include pipes for transporting the fluid, valves for controlling the fluid transport (such as pressure regulating valves and flow regulating valves), and other necessary components (such as pumps). Fluid flow within a piping system generates noise, particularly from pressure regulating valves and flow regulating valves. Therefore, silencers are usually required in piping systems to reduce noise.

[0004] Known silencers typically consist of an interconnected housing and a perforated cover, along with a noise attenuation device housed within the space formed by the housing and the perforated cover. The housing is usually a custom-made, forged or cast component, lacking versatility. The housing and perforated cover require connection to a piping system via additional interfaces, the form of which varies depending on the specific structure to be connected. Furthermore, the noise attenuation device, assembled from perforated plate assemblies, support members, and fasteners, is then inserted into the housing. The distance between the perforated plate assemblies is determined by the lengths of multiple support members. Adjusting the distance between the perforated plate assemblies during assembly requires support members of varying lengths, making adjustment inconvenient.

[0005] Therefore, known mufflers are expensive, have low versatility, and are not convenient for adjusting the structure of the noise attenuation device as needed. Utility Model Content

[0006] The purpose of this invention is to solve one or more of the technical problems mentioned above.

[0007] Specifically, the purpose of this invention is to provide a muffler that can reduce manufacturing costs.

[0008] In particular, another objective of this invention is to provide a muffler that is versatile.

[0009] In particular, a further objective of this invention is to provide a silencer in which the structural configuration of the noise attenuation device can be easily adjusted as needed during assembly.

[0010] According to one aspect of the present invention, a silencer for a piping system is provided. The silencer includes: a body defining a fluid inlet, a fluid outlet, and an internal fluid channel located between the fluid inlet and the fluid outlet, the body including a reducer; and a noise attenuation device disposed in the internal fluid channel.

[0011] According to the technical solution of this utility model, the noise attenuation device of the silencer is disposed in an internal fluid channel defined by a body including a reducer. Since the reducer is a component that already exists in or needs to be installed in the piping system, there is no need to add an additional housing to the silencer in the piping system, thereby reducing manufacturing costs. Furthermore, the reducer is a standard universal component, which can improve the flexibility and versatility of the silencer. The silencer provided by this utility model can replace any reducer assembly that does not meet noise requirements already existing in the piping system without significantly altering the existing piping system. Alternatively, the silencer provided by this utility model can be used as a reducer assembly that is already required in the piping system.

[0012] Optionally, the reducer has a small end and a large end with an inner diameter larger than that of the small end. The body further includes: an inlet flange connected to the small end; and an outlet flange connected to the large end. The inlet and outlet flanges facilitate installation of the reducer in a piping system. Both the inlet and outlet flanges are standard, universal parts, and do not affect the flexibility and versatility of the silencer.

[0013] Optionally, the noise attenuation device is connected to the inner wall of one or more of the reducer, the inlet flange, and the outlet flange. This improves the stability and strength of the noise attenuation device.

[0014] Optionally, the noise attenuation device includes a perforated plate component or a plurality of perforated plate components spaced apart along the axis of the internal fluid channel. Including a single perforated plate component can reduce manufacturing costs, while including multiple perforated plate components spaced apart along the axis of the internal fluid channel can achieve step-by-step noise reduction.

[0015] Optionally, the perforated plate component includes a single perforated plate and / or a perforated plate assembly formed by combining multiple perforated plates. A perforated plate component comprising a single perforated plate facilitates assembly and reduces manufacturing costs. A perforated plate component comprising a perforated plate assembly formed by combining multiple perforated plates can form a perforated plate assembly of the desired thickness by combining multiple thinner perforated plates. Because each perforated plate is thin, holes in each perforated plate can be machined without using costly machining drilling methods. For example, low-cost punching or laser drilling methods can be used to machine holes in each thin perforated plate, or low-cost commercially available pre-made perforated plates can be selected, all of which significantly reduce manufacturing costs.

[0016] Optionally, the silencer includes reinforcing ribs connected to the perforated plate member on the side near the fluid outlet. The reinforcing ribs can increase the strength of the perforated plate member, thereby improving its resistance to fluid impact.

[0017] Optionally, the reinforcing ribs are connected to the inner wall of the body. This further improves the stability of the reinforcing ribs, thereby further enhancing the porous plate assembly's resistance to fluid impact.

[0018] Optionally, the noise attenuation device includes the plurality of porous plate components, and the reinforcing ribs are disposed on the side of a portion of the porous plate components near the fluid outlet. Therefore, an appropriate number of reinforcing ribs can be provided as needed to minimize manufacturing costs while meeting strength requirements.

[0019] According to another aspect of this utility model, a piping system is provided. The piping system includes any of the aforementioned silencers. Because this piping system incorporates any of the aforementioned silencers, it also possesses the beneficial effects of any of the aforementioned silencers. For the sake of brevity, further details are omitted here. Attached Figure Description

[0026] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The following description is exemplary in nature and is not intended to limit the present invention or its application or use.

[0027] This utility model provides a silencer for a pipeline system and a pipeline system having the silencer. Figure 1 A schematic diagram of a piping system 1 according to a preferred embodiment of the present invention is shown. Figure 2 A schematic diagram of a piping system 1' according to another preferred embodiment of the present invention is shown. Figure 1 Piping system 1 and shown in the figure Figure 2 The piping systems 1' shown are all equipped with the silencers 10 provided by this utility model.

[0028] Figure 1 Piping system 1 and shown in the figure Figure 2 The pipeline systems 1' shown can all be used to transport fluids, such as natural gas. Figure 1 and Figure 2 The arrows in the diagram indicate the direction of fluid flow in piping systems 1 and 1'. For example... Figure 1 As shown, the piping system 1 includes pipes (e.g., a first pipe 11) for conveying fluid and valves 12 for controlling the conveyance of fluid. Valve 12 can be a pressure regulating valve, a flow regulating valve, etc. Figure 1 Piping system 1 and shown in the figure Figure 2 In the piping system 1' shown, reducers 110 are typically used as enlarged pipes. For example, in a preferred embodiment of this invention, such as Figure 1 As shown, the inner diameter of the outlet of valve 12 is different from the inner diameter of the first pipe 11, and a reducer 110 is disposed between the outlet of valve 12 and the inlet of the first pipe 11. For example, in another preferred embodiment of this utility model, such as... Figure 2 As shown, the pipeline system 1' includes a first pipe 11 and a second pipe 13 with different inner diameters for conveying fluid, and a reducer 110 is disposed between the first pipe 11 and the second pipe 13.

[0029] Noise is typically generated during the flow of fluid in pipeline system 1. For example, at valves 12 such as pressure regulating valves and flow regulating valves, turbulence is generated due to sudden changes in the flow area, resulting in turbulent noise. This turbulent noise also occurs at other locations where the inner diameter changes, such as between the first pipe 11 and the second pipe 13 in pipeline system 1'. This invention cleverly incorporates a noise attenuation device 200 for reducing noise. Figures 3 to 5 The reducer 110 or its related structure (e.g., those that are already present or need to be installed in the piping systems 1 and 1') is installed in the piping system. Figures 3 to 5 In the inlet flange 120 or outlet flange 130 shown and described below, no additional housing is required, reducing manufacturing costs.

[0030] The following will combine Figures 3 to 5 The silencer 10 provided by this utility model is described in detail. Figure 3 A perspective view of a muffler 10 according to a preferred embodiment of the present invention is shown.

[0031] Figure 4 It shows Figure 3 The diagram shows a cross-sectional view of the muffler 10. Figure 5 It shows Figure 3 The diagram shows a side view of the muffler 10.

[0032] like Figures 3 to 5As shown, a silencer 10 according to a preferred embodiment of the present invention includes a body 100. The body 100 includes a reducer 110. The reducer 110 can be a concentric reducer or an eccentric reducer. The reducer 110 is a standard universal component suitable for any piping system 1, 1'. Specifically, the reducer 110 can be a commercially available reducer conforming to standards such as the American Society of Mechanical Engineers (ASME) or the National Standard of the People's Republic of China (GB). The reducer 110 has a small end 111 with a smaller inner diameter and a large end 112 with an inner diameter larger than that of the small end 111. The body 100 of the silencer 10 also includes an inlet flange 120 connected to the small end 111 of the reducer 110 and an outlet flange 130 connected to the large end 112 of the reducer 110. The inlet flange 120 and the outlet flange 130 are also standard universal components. The inlet flange 120 and the outlet flange 130 can be connected to the small end 111 and the large end 112 of the reducer 110, respectively, by welding, for example. The inlet flange 120 and outlet flange 130 facilitate the installation of the reducer 110 in piping systems 1, 1'. It should be noted that in other embodiments not shown in this invention, one or both of the inlet flange 120 and outlet flange 130 may be omitted. The small end 111 and large end 112 of the reducer 110 can be directly connected to a pipe (e.g., the first pipe 11 or the second pipe 13) or the outlet of valve 12 in piping systems 1, 1'. For example, the small end 111 and large end 112 of the reducer 110 can be directly welded to a pipe (e.g., the first pipe 11 or the second pipe 13) in piping systems 1, 1' or directly welded to the outlet of valve 12 in piping systems 1, 1'.

[0033] like Figure 3 and Figure 4 As shown, the body 100 of the silencer 10 defines a fluid inlet 140, a fluid outlet 150, and an internal fluid passage 160 located between the fluid inlet 140 and the fluid outlet 150. Specifically, in a preferred embodiment of the present invention, the fluid inlet 140 is defined by the end of the inlet flange 120 away from the reducer 110; the fluid outlet 150 is defined by the end of the outlet flange 130 away from the reducer 110; and the internal fluid passage 160 is defined by the inlet flange 120, the reducer 110, and the outlet flange 130. It can be understood that in embodiments where the inlet flange 120 and the outlet flange 130 are omitted, the fluid inlet 140 may be defined by the small end 111 of the reducer 110, the fluid outlet 150 may be defined by the large end 112 of the reducer 110, and the internal fluid passage 160 may be defined by the reducer 110.

[0034] like Figure 4As shown, the silencer 10 also includes a noise attenuation device 200 disposed in the internal fluid passage 160 to reduce the noise generated by the fluid as it flows through the noise attenuation device 200. The noise attenuation device 200 can be any device that can be disposed in the internal fluid passage 160, allows fluid to flow through, and attenuates noise. Since the noise attenuation device 200 is disposed in the internal fluid passage 160 defined by the body 100 including a reducer 110 and optionally an inlet flange 120 and an outlet flange 130, wherein the reducer 110 is a component that is already present or required in the piping systems 1, 1', there is no need to add an additional housing to the silencer 10 in the piping systems 1, 1', thereby reducing manufacturing costs. In addition, the reducer 110 and the optional inlet flange 120 and outlet flange 130 are standard general-purpose parts, which can improve the flexibility and versatility of the silencer 10. The silencer 10 provided by this utility model can replace any reducer assembly that does not meet noise requirements that already exists in the existing piping system without significantly changing the existing piping system. Alternatively, the silencer 10 provided by this utility model can be used as a reducer assembly that is required in the pipeline system itself.

[0035] Specifically, in a preferred embodiment of this utility model, such as Figure 4 As shown, the noise attenuation device 200 includes a perforated plate assembly 210 (as an example of a "perforated plate component"), which comprises a plurality of perforated plates 211 joined together. The plurality of perforated plates 211 can be joined together by any suitable method such as welding, bonding, or threaded fasteners. Each perforated plate 211 can be a thin plate. For example, the thickness of each perforated plate 211 can be 1 mm to 2 mm. By joining a plurality of thin perforated plates 211 together, a perforated plate assembly 210 of the desired thickness can be formed. Because each perforated plate 211 is thin, holes can be machined on each perforated plate 211 without the need for costly machining drilling. For example, low-cost punching or laser drilling can be used to machine holes on each thin perforated plate 211, or low-cost commercially available pre-made perforated plates can be selected, all of which significantly reduce manufacturing costs.

[0036] The noise attenuation device 200 may include only one porous plate assembly 210 to reduce costs. For example... Figure 4As shown, in a preferred embodiment of the present invention, the noise attenuation device 200 includes a plurality of perforated plate assemblies 210 spaced apart along the axis L of the internal fluid channel 160, as needed, to reduce noise in stages. The plurality of perforated plate assemblies 210 can be arranged at a uniform spacing throughout the entire internal fluid channel 160. Alternatively, the plurality of perforated plate assemblies 210 can be arranged only on a portion of the internal fluid channel 160. For example, the perforated plate assemblies 210 can be arranged only in the region of the internal fluid channel 160 located at the inlet flange 120, only in the region of the internal fluid channel 160 located at the reducer 110, only in the region of the internal fluid channel 160 located at the outlet flange 130, or in any two of the aforementioned regions. For example, in a preferred embodiment of the present invention, such as... Figure 4 As shown, the noise attenuation device 200 includes six perforated plate assemblies 210, of which four perforated plate assemblies 210 are disposed in the region of the internal fluid channel 160 located in the reducer 110, and the other two perforated plate assemblies 210 are disposed in the region of the internal fluid channel 160 located in the outlet flange 130.

[0037] Preferably, the perforated plate assembly 210 of the noise attenuation device 200 can be connected to the inner wall of one or more of the reducer 110, inlet flange 120, and outlet flange 130 to improve the stability and strength of the perforated plate assembly 210. When the noise attenuation device 200 includes a plurality of perforated plate assemblies 210 spaced apart, by connecting the perforated plate assemblies 210 to the inner wall of one or more of the reducer 110, inlet flange 120, and outlet flange 130, adjacent perforated plate assemblies 210 can be spaced apart without the need for supporting members between them, and the perforated plate assemblies 210 can be assembled according to the desired spacing between adjacent perforated plate assemblies 210, facilitating adjustment of the spacing between the perforated plate assemblies 210 during assembly.

[0038] Specifically, in a preferred embodiment of this utility model, such as Figure 4 As shown, the perforated plate assembly 210 is connected to the inner walls of the reducer 110 and the outlet flange 130. As mentioned above, the perforated plate assembly 210 can also be disposed in the region of the internal fluid passage 160 located at the inlet flange 120; therefore, the perforated plate assembly 210 can also be connected to the inner wall of the inlet flange 120. The perforated plate assembly 210 can be connected to the inner walls of one or more of the reducer 110, the inlet flange 120, and the outlet flange 130 by any suitable means, such as welding or bonding.

[0039] Preferably, such as Figures 3 to 5As shown, the muffler 10 also includes a reinforcing rib 300. The reinforcing rib 300 can be a cross-shaped rib, an X-shaped rib, or any other suitable shape. The reinforcing rib 300 is connected to the porous plate assembly 210 on the downstream side, i.e., the side of the porous plate assembly 210 near the fluid outlet 150. The reinforcing rib 300 located on the downstream side of the porous plate assembly 210 can increase the strength of the porous plate assembly 210, thereby improving its resistance to fluid impact. Preferably, the reinforcing rib 300 is also connected to the inner wall of the body 100 to further improve the stability of the reinforcing rib 300, thereby further enhancing the resistance of the porous plate assembly 210 to fluid impact. It is understood that when the reinforcing rib 300 is used to reinforce the porous plate assembly 210 located in the reducer 110, the reinforcing rib 300 can be connected to the inner wall of the reducer 110. Similarly, when the stiffener 300 is used to reinforce the perforated plate assembly 210 located in the inlet flange 120 or the outlet flange 130, the stiffener 300 can be connected to the inner wall of the inlet flange 120 or the outlet flange 130.

[0040] When multiple porous plate groups 210 are spaced apart along the axis L of the internal fluid channel 160, each porous plate group 210 may have a reinforcing rib 300 on the side facing the fluid outlet 150. Preferably, depending on the specific fluid pressure and the strength requirements of the porous plate group 210, only a portion of the porous plate groups 210 may have reinforcing ribs 300 on the side facing the fluid outlet 150, in order to minimize manufacturing costs while meeting strength requirements. For example, in a preferred embodiment according to this utility model, such as Figure 4 As shown, reinforcing ribs 300 can be provided only on the side of the three porous plate groups 210 near the fluid outlet 150 facing the fluid outlet 150.

[0041] It should be noted that, although in Figures 3 to 5In the illustrated embodiment, the perforated plate component of the noise attenuation device 200 is shown as a perforated plate assembly 210 formed by combining multiple perforated plates 211. However, in other embodiments not shown in this invention, the perforated plate component of the noise attenuation device 200 may be a single perforated plate, which may have a suitable thickness, for example, the thickness of the perforated plate assembly 210 formed by combining multiple thin perforated plates. By setting the perforated plate component as a single perforated plate, the assembly process of the muffler 10 can be simplified, and the manufacturing cost can be reduced. As needed, the noise attenuation device 200 may include multiple single perforated plates of suitable thickness arranged at intervals, or only one single perforated plate. The single perforated plate may also be provided with reinforcing ribs 300 in a similar manner as described above with reference to the perforated plate assembly 210, which will not be repeated here for the sake of simplicity. In addition, as needed, the noise attenuation device 200 may also include a combination of the single perforated plate and the perforated plate group 210 described above. That is, in a muffler 10, the perforated plate component of the noise attenuation device 200 may include a combination of the perforated plate group 210 and the single perforated plate.

[0042] In summary, according to the technical solution of this utility model, the noise attenuation device 200 of the silencer 10 is disposed in an internal fluid channel 160 defined by a body 100 including a reducer 110 and optionally an inlet flange 120 and an outlet flange 130. Since the reducer 110 is a component that already exists or needs to be installed in the piping systems 1 and 1', there is no need to add an additional housing to the silencer 10 in the piping systems 1 and 1', reducing manufacturing costs. Furthermore, the reducer 110 and the optional inlet flange 120 and outlet flange 130 are all standard universal parts, which can improve the flexibility and versatility of the silencer 10. The silencer 10 provided by this utility model can replace any reducer assembly that does not meet noise requirements already existing in the piping system without significantly altering the existing piping system. Alternatively, the silencer 10 provided by this utility model can be used as a reducer assembly that already needs to be installed in the piping system.

[0043] Furthermore, the silencer 10 provided by this invention improves the stability and strength of the noise attenuation device 200 by connecting the noise attenuation device 200 to the inner wall of one or more of the reducer 110, inlet flange 120, and outlet flange 130. In particular, when the noise attenuation device 200 includes multiple perforated plate components spaced apart (each perforated plate component can be a single perforated plate or a perforated plate assembly 210 formed by combining multiple perforated plates), by connecting the perforated plate components (e.g., perforated plate assembly 210) of the noise attenuation device 200 to the inner wall of one or more of the reducer 110, inlet flange 120, and outlet flange 130, adjacent perforated plate components can be spaced apart without the need for supporting members between them. Moreover, the perforated plate components can be assembled according to the desired spacing between adjacent perforated plate components, facilitating adjustment of the spacing between the perforated plate components during assembly.

[0044] It should be understood that various different implementation methods can be designed by combining or modifying different implementation methods and various technical features in different ways.

[0045] The foregoing description, in conjunction with specific embodiments, describes a silencer for a piping system and a piping system having the silencer according to a preferred embodiment of the present invention. It is understood that the above description is exemplary and not restrictive, and various modifications and variations will arise in those skilled in the art from the above description without departing from the scope of the present invention. These modifications and variations are also included within the scope of protection of this application.
