Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of silencers, and in particular relates to a pipeline silencer. Background Art
[0002] The pipe is an indispensable component in the ventilation system. When the fan is running and the air is extracted, the gas flows rapidly in the pipe, and friction occurs between the gas and the gas and the inner wall of the pipe, resulting in high noise in the pipe, so noise reduction is needed. Noise pollution is becoming more and more serious, and the silencer has a significant effect on reducing various industrial noises. The silencer is a device that blocks the propagation of sound while allowing airflow to pass through. It is an important measure to eliminate aerodynamic noise. It is usually installed on the ventilation duct of aerodynamic equipment (such as blowers, air compressors, boiler exhaust ports, generators, water pumps and other equipment with high exhaust noise) or in the intake and exhaust systems to reduce noise. The opening end of the muffler in the prior art is not provided with components such as plugs, and foreign impurities can easily enter the muffler, causing blockage in the muffler, affecting the normal operation of the muffler, and is not conducive to the actual use of the user.
[0003] The existing patent literature discloses a utility model patent for a PE pipe silencer (Announcement No.: CN213541651U). Its technical solution records that two connecting ends are butt-jointed on both sides of the shell, and the inner walls of the two connecting ends include protrusions. The air duct can be clamped in the two connecting ends, and the protrusions can fix the ventilation duct; the middle part of the shell includes a silencer structure, but no plugs or other components are provided on the connecting ends, and the above-mentioned problems also exist. Impurities can easily enter the inside of the shell, affecting the normal operation of the silencer structure. Utility Model Content
[0004] The utility model aims to provide a technical solution for a pipe silencer in view of the deficiencies in the prior art. The utility model has a reasonable design, a sophisticated structure, and a good use effect. The plugs are symmetrically arranged at both ends of the silencer to prevent external impurities from entering the shell and clogging the internal structure, thereby ensuring normal use by users. The pipe silencer is installed between pipes to achieve the effect of sound absorption and noise reduction, thereby ensuring the user's comfort. The setting of the necked section can achieve a certain buffering effect and a noise reduction effect, and will not cause heat loss, thereby having high practicality.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] The pipe silencer includes a shell, a pipe connection and a plug. The shell is provided with a mounting section, which is symmetrically arranged at both ends of the body. The pipe connection includes a pipe head section, a pipe body section and a guide section. The pipe body section is located between the pipe head section and the guide section. The guide section is located in the shell. The guide section is provided with a constriction section and a through hole. The plug is connected to the pipe connection. The plug blocks the pipe connection to prevent impurities from entering the pipe connection. The pipe connection realizes the inflow and outflow of airflow. The pipe silencer performs noise reduction processing, improves the user's comfort, and facilitates the user's use. The constriction section can play a certain buffering role on the airflow, play a noise reduction effect, and further play a better noise reduction effect.
[0007] Furthermore, a transition section is provided between the installation section and the housing, and the transition section strengthens the structural strength of the housing.
[0008] Furthermore, the connecting pipes are symmetrically distributed at both ends of the shell, ensuring the inflow and outflow of airflow and having a beautiful structure.
[0009] Furthermore, at least two through holes and two constricted sections are provided, and the through holes and the constricted sections are evenly distributed along the guide portion. The airflow flows in and out of the through holes, and the through holes can ensure that the airflow flows in and out of the muffler quickly, and the constricted sections increase the aesthetics of the structure.
[0010] Furthermore, the through hole and the necking section are staggered, and the structural strength of the necking section is low, so the through hole and the necking section are staggered to ensure the structural strength of the through hole.
[0011] Furthermore, the plug is made of copper, which has good thermal conductivity and strong corrosion resistance, is convenient for practical use, prolongs the service life of the plug, and reduces the cost of later replacement and repair.
[0012] Furthermore, the shell and the pipe are both made of stainless steel. The stainless steel structure has high strength, good overall stability, strong corrosion resistance, long service life, low maintenance rate, and is convenient for users to use.
[0013] Furthermore, the pipe is an integrally formed structure, which has high strength and long service life.
[0014] Furthermore, an inner shell is arranged inside the shell, a gap cavity is formed between the inner shell and the shell, and the gap cavity is filled with sound insulation cotton. The inner shell further strengthens the structural strength of the shell, which is convenient for practical use, and the sound insulation cotton can further play a role in sound absorption and sound reduction, achieving a better noise reduction effect, and at the same time has good heat insulation and is easy to use.
[0015] Furthermore, the inner shell is provided with sound-absorbing holes, which can further reduce noise while not affecting the rapid passage of airflow, and are highly practical.
[0016] The utility model has the following beneficial effects due to the adoption of the above technical solution:
[0017] The utility model has a reasonable design, sophisticated structure and high practicality. The connection between the pipe silencer and the pipe is realized through the pipe connection. The airflow flows from the pipe into the shell through the pipe, and plays a certain buffering role through the shrinking section, thereby achieving the effect of noise reduction. The plugs are symmetrically arranged at both ends of the silencer to prevent external impurities from entering the shell and causing blockage of the internal structure. The plugs are made of red copper, which has strong corrosion resistance and long service life. The shell and the pipe are both made of stainless steel structure. The stainless steel structure has high strength and good overall stability. The setting of the sound insulation cotton further improves the sound absorption effect, and the use effect is good.

The pipe silencer is used to reduce noise, improve the user's comfort and facilitate the user's use. The necking section 17 can play a certain buffering role on the airflow, thereby achieving a noise reduction effect.
[0027] A transition section 4 is provided between the mounting section 5 and the housing 1. The transition section 4 strengthens the structural strength of the housing 1 and prevents airflow from rushing into the housing 1 and causing impact on the housing 1.
[0028] The pipes 2 are symmetrically distributed at both ends of the housing 1, ensuring the inflow and outflow of airflow and having a beautiful structure.
[0029] At least two through holes 9 and at least two constricted sections 17 are provided, and the plurality of through holes 9 and the plurality of constricted sections 17 are evenly distributed along the guide section 8.

[0030] The through hole 9 is staggered with the necking section 17. The structural strength at the necking section 17 is relatively low, and the through hole 9 is staggered with the necking section 17 to ensure the structural strength at the through hole 9.
[0031] The plug 3 is made of copper. Copper has good thermal conductivity and strong corrosion resistance, is convenient for practical use, prolongs the service life of the plug 3, and reduces the cost of later replacement and repair.
