Technical Field
The utility model relates to an ambient noise elimination equipment technical field, in particular to pipeline valve sound insulation cover.
Background
In industrial production and life, common valves include a shut-off valve, a regulating valve, a check valve, a flow divider and a safety valve. Valve noise is an important noise source in industrial production and is commonly found in the industrial fields of metallurgy, electric power, petrochemical industry and the like. For example, main steam pipelines of nuclear power plants, thermal power plants; exhaust valves of high-pressure furnaces and fans of oil refining chemical plants; sea pipelines for ships and submarines; the noise sound pressure level of the common pipeline valves, especially the nearby large pipeline valves, such as air pipe valves and air compressor valves of air conditioning systems is more than 100 decibels, which brings disturbance to the industrial production and life of people. The main source of noise in valves is from the pressure differential created during the fluid flow, which causes the fluid flowing inside the valve to impact and achieve high noise levels, typically up to 115 db. The traditional mode of making an uproar falls adopts pipeline and embedded muffler that the wall thickness is bigger, and this kind of mode cost is higher, and the face of making an uproar falls widely and does not have the key, lacks the noise that produces valve department and carries out local noise reduction processing, and to the local noise processing aspect of producing in valve department, the noise reduction effect is not very ideal.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing a pipeline valve sound insulation cover that the structure is simpler, be applicable to that the pipeline valve is local to be fallen and makes an uproar, the noise reduction effect is better.
In order to realize the purpose of the utility model, the utility model adopts the following technical scheme: the utility model provides a pipeline valve sound-proof cover, the cover is established at the periphery side of pipeline valve, pipeline valve sound-proof cover include metal crate, sound insulation housing and bolt, metal crate hoop cover on the pipeline at valve both ends and pass through the bolt-up, sound insulation housing fixed mounting be in metal crate on, the sound insulation housing form, a plurality of by the mutual concatenation of a plurality of sound insulation panels the sound insulation panel enclose jointly and become the sound insulation room that is used for holding the valve, each the sound insulation panel all include by interior to outer compound aperture metal plate in proper order, inhale sound cotton, damping sound insulation layer and metal sheet.
In the above technical solution, preferably, the pipe valve sound insulation cover is rectangular.
In the above technical scheme, preferably, the sound insulation amount of the pipe valve sound insulation cover is 25-45 decibels.
In the above technical scheme, preferably, the sound-absorbing cotton is one of glass cotton, polyester fiber cotton, rock wool, mineral cotton and egg cotton.
In the above technical solution, preferably, the damping and sound insulation layer has a composite layer structure of a gypsum board, a damping and sound insulation felt, and a glass magnesium board sequentially compounded from inside to outside along the radial direction
The utility model discloses a periphery side at the pipeline valve sets up the sound insulation housing, the sound insulation housing has the sound proof room that is used for holding the valve, the sound insulation housing is the composite bed structure, it includes by interior to outer compound metal orifice plate in proper order, inhale the sound cotton, damping sound insulation layer and metal sheet, a part of noise that spreads from valve department can see through the metal orifice plate and turn into heat energy with sound energy, the noise cotton absorption is inhaled to another part's noise, the noise transmission is reduced by the separation behind damping sound insulation layer and the metal sheet, the local noise reduction effect of valve is showing, the structure is simpler.
Drawings
FIG. 1 is a schematic structural view of the check valve of the present invention applied to a pipeline;
wherein: 100. a pipeline valve sound insulation cover; 101. a high temperature high pressure pipeline; 102. a valve; 11. a metal frame; 12. a sound insulating panel.
Detailed Description
To explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following detailed description is made with reference to the accompanying drawings.
As shown in fig. 1, the pipe valve sound-proof housing 100 is a rectangular parallelepiped, and includes a sound-proof housing, a metal frame 11, and bolts. The metal frame 11 is hooped on the pipeline 101 provided with the valve 102 and is fastened by bolts, and the sound insulation housing is fixedly arranged on the metal frame 11 and is provided with a sound insulation chamber for accommodating the valve. Specifically, the sound insulation housing is formed by splicing a plurality of sound insulation panels 12, and a plurality of sound insulation panels are fixed respectively on the installation frame 11 and enclose into the above jointly sound insulation chamber, each sound insulation panel 12 is a composite layer structure, and comprises a metal pore plate, sound absorption cotton, a damping sound insulation layer and a metal plate which are sequentially compounded from inside to outside. The pipeline 101 is a high-temperature high-pressure pipeline, and the valve 102 is a check valve (check valve), but may be other valves such as a throttle valve, a regulating valve, and a shut-off valve. The metal material of the metal frame 11 is preferably steel structure, which has high structural strength and stable installation. The pipeline valve sound insulation cover is fastened by bolts, so that the pipeline valve sound insulation cover is convenient to mount and dismount and is convenient to maintain. The sound-absorbing cotton comprises one of glass cotton, polyester fiber cotton, rock wool, mineral wool and egg cotton. The damping sound insulation layer is a composite layer structure of a gypsum board, a damping sound insulation felt and a glass magnesium board which are sequentially compounded from inside to outside, so that the vibration of the metal plate can be inhibited, and the sound insulation performance is good. The metal materials of the metal pore plate and the metal plate can be selected from steel plates, aluminum alloys, aluminum plates and the like, and can also be selected from other silencing metal materials, the metal pore plate is formed by arranging tiny through holes on the metal plate, and the purpose is to allow sound waves to pass through, and the sound waves rub small holes of the metal pore plate, so that sound energy is converted into heat energy, and the energy of the sound is reduced. And one part of the noise generated at the valve passes through the small holes on the metal pore plate and is converted into heat energy to reduce sound energy, and the other part of the noise is absorbed by the sound-absorbing cotton and finally separated by the damping sound-insulating layer and the metal plate, so that the local noise reduction effect is remarkable.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
