Abstract
The utility model discloses a pipeline muffler which comprises a muffler shell body, wherein, the inner wall of the muffler shell body is provided with a damping element, a sound absorption and elimination block is arranged on the inner wall of the damping element and the muffler shell body comprises an upper half shell body and a lower half shell body which are fixedly connected. The pipeline muffler is a noise-reduction pipeline muffler that the pipelines of a pipe transmission system is capable of being and is easy to be disassembled and assembled under the working condition that the shutdown can not be changed during the production and operation.
Description
Technical field
The utility model relates to a kind of silencing apparatus, especially a kind of silencing apparatus of carrying high pressure water, feed channel that is applicable to.
Background technique
In oil, chemical industry, Gas Industry; for fed sheet of a media is the conveyance conduit of high pressure water, gas (rock gas or harmful gas); present applied duct attenuation apparatus is a monolithic construction; insert sound absorption in bulk, muffler material in the molded housing after machining; after machine shaping; silencing apparatus is installed in plays the noise elimination effect in the air delivering pipeline, but under work condition state, can't shut down duct attenuation apparatus the pipeline installation forming.
In patent 00252851.7, also disclose a kind of duct attenuation dress device, reached the noise reduction purpose in pipeline, still, can not under the pipeline operating mode, carry out dismounting by housing, sound-absorbing, sound insulation and noise reducing body and damping support block are installed.
The model utility content
The purpose of this utility model provides a kind of pipeline of pipe communication system and can't change in production run under the working condition of shutdown, can dismounting and easy-to-disassemble and assemble noise reduction duct attenuation device.
For achieving the above object, the utility model adopts following technological scheme: comprise suppressor case, be equipped with between suppressor case and pipeline and inhale the noise elimination piece that suppressor case comprises upper half-shell and housing lower half, both removably connect.
On the suppressor case inwall, damping member is housed.
Between damping member and suction noise elimination piece, upper and lower half enclosure interior of duct attenuation device also radially is installed with the sound insulation support of annular.
Duct attenuation device outside is not coated with positioning plate fully, and the positioning plate outer radial is provided with upper and lower ring-shaped clip and both bolts connect.
Inhale the position of noise elimination piece correspondence in two ends of duct attenuation device, also be pasted with the end face seal damping plate of annular, also be pasted with pipe in the end of end face seal damping plate inner ring pipeline correspondence and connect the sealing damping plate.
The utility model adopts the suction ball joint of machine shaping is gone in upper and lower half housing, pipeline is under the situation that operating mode can't be shut down like this, with regard to dismantled and assembled duct attenuation device, under strong noise source harm situation, can reduce noise 20-25dB (A), when line transportation rock gas or harmful gas, also can be fire-retardant; The damping member of packing between suction noise elimination piece and suppressor case can better be eliminated noise; Upper and lower half enclosure interior radially sets firmly the sound insulation support of annular can conveniently inhale noise elimination piece and damping member stationary positioned; The outside upper and lower clip that adopts positioning plate to be connected with the positioning plate outer bolt of suppressor case can make upper and lower half housing be fastenedly connected fully; The position of inhaling noise elimination piece correspondences in two ends of duct attenuation device is pasted with the end face seal damping plate of annular, also is pasted with pipe in the end of end face seal damping plate inner ring pipeline correspondence and connects the sealing damping plate, can prevent that sound source from outwards overflowing from pipeline opening; Certainly, except common pipe, can also install corresponding gas pipeline silencing apparatus noise reduction additional to the noise pipeline of elbow, threeway and special-shaped pipeline.
Description of drawings
Fig. 1 is the plan view of duct attenuation device;
Fig. 2 is the left view of duct attenuation device.
Embodiment
Shown in the left view of the plan view of the duct attenuation device of Fig. 1 and figure two: comprise suppressor case, be equipped with on the suppressor case inwall and inhale noise elimination piece 4 that suppressor case comprises upper half-shell 11 and housing lower half 12, both removably connect.
Between suppressor case and suction noise elimination piece 4, damping member 3 is housed.
Between damping member 3 and suction noise elimination piece 4, upper and lower half housing of silencing apparatus pipeline 11,12 inside also radially are installed with the sound insulation support 2 of annular.
Suppressor case 1 outside is not coated with positioning plate 5 fully, and the positioning plate outer radial is provided with upper and lower ring-shaped clip 61,62 and both connect with bolt 9.
Inhale the position of noise elimination piece 4 correspondences in two ends of gas pipeline silencing apparatus, also be pasted with the end face seal damping plate 7 of annular, also be pasted with pipe in the end of end face seal damping plate 7 inner ring pipeline correspondences and connect sealing damping plate 8.
When under the pipeline operating mode, using, the suction noise elimination piece 4 of machine shaping and damping member 3 can be packed in upper and lower half housing 11,12, inhale noise elimination piece 4, damping member 3 by sound insulation support 2 stationary positioned, again upper and lower half housing 11,12 is installed on the pipeline 10, placement positioning plate 5 on upper half-shell 11 is installed upper and lower ring-shaped clip 61,62 and fixedly connected with bolt 9 on positioning plate 5; When dismantling, only need back out bolt 9, the anti-order dismounting during again according to installation gets final product.Certainly, except common pipe, can also install corresponding gas pipeline silencing apparatus noise reduction additional to the noise pipeline of elbow, threeway and special-shaped pipeline.
