Description
Technical field
The utility model is a kind of natural gas line built-in general-purpose type silencer.Relate to the pipe-line system technical field.
Background technique
The aerodynamic noise that exists in the field, natural gas line station is mainly produced by positions such as pressure regulator valve, header and pipeline reducing diameters.The pressure regulator valve that pipeline uses is the main source of noise, can meet the demands for its noise great majority of the pressure regulator valve that carries silencer, but the noise field measurement that does not have to produce behind the common pressure regulator valve of silencer can reach more than the 100dB.Noise mainly is because turbulent flow after the valve port of institute's gas transmission body through regulator and eddy current produce behind the pressure regulator valve, is promptly interacted by turbulent fluid and regulator or inner surface of pipeline and generation.Pass through positions such as pipeline header and reducing when rock gas, the mechanical energy of fluid can convert acoustic energy into and produce noise.
" a kind of be used to be installed in the silencing apparatus on the rock gas residual air drain " (patent No.: 99251820.2) by suction tude, lower chamber, device of air, gas-distributing pipe, upper gas chamber, cross tracheae, steam outlet pipe constitutes.After each part manufacturing is good, link together with welding method.Its principle science, simple in structure, have purposes widely.Can select different model for use according to the size of emptying tolerance, also can parallel connection use.Effect: can reduce noise more than 20%.When the emptying amount 30 * 10
4During cubic meter/sky, noise is not higher than 60 decibels.But be not suitable for the noise control at pressure regulator valve place, high pressure gas pipeline road.
Our company in " the silencer rectifier behind a kind of gas pipeline modulating valve " of on December 10th, 2010 application (application number: 2010105884570) by the connection of leading portion fixedly the weldless tube of pipeline section and back three sections various outer diameters be welded successively from big to small by external diameter; Be evenly equipped with wide seam of 0.9-1.1mm vertically around the tube wall of the three sections steel pipes in back, the quantity of bar seam is confirmed that by the spacing that realizes the noise elimination effect bar seam length and hush tube radius are confirmed by the bar seam area and the relation in the outer airflow of device cross section.It has reduced the noise in the field, gas pipeline station, alleviates the physical and mental health influence of noise to a station interior staff, satisfies the requirement of country to ambient noise, and simple in structure.But deficiency is that the bar seam is long, is adding the distortion that is prone to cause body man-hour.
The model utility content
The purpose of the utility model be a kind of elimination volute tongue controlled with natural gas line of design within national Specification, do not influence the natural gas line built-in general-purpose type silencer of the conveying of pipeline.
Principle: make air communication cross the narrow strip seam, improve the frequency of pneumatic noise, be higher than the frequency range that people's ear can be accepted sound, reach the purpose that reduces noise; Simultaneously through the streamline cowling, changed the velocity distribution after air communication is crossed silencer, avoided the generation of eddy current, reduce noise; The high-frequency noise that the air-flow that flows out from interior pipe produces can be carried out selective filter according to frequency by the expansion chamber that forms between inner and outer pipes and cowling, a part of noise is reflected back, thereby reduce noise; The use of two kinds of calibers, can make outer tube internally the high-frequency noise that produces of pipe place intercept, reduce outside transmission capacity.
The structure of the utility model such as Fig. 1-shown in Figure 2, silencer is welded to each other by pipe 3, end socket 5 and streamline cowling 6 in flange plate 1, noise elimination outer tube 2, the noise elimination and forms.There are in the noise elimination that is with end socket 5 in the noise elimination outer tube 2 of streamline cowling 6 pipe 3 one ends be connected with state dimensioning flange plate 1 in the lump.
Wherein:
There is transfer port 7 at flange plate 1 center, and transfer port 7 peripheries have a plurality of standard measure bolts hole 8 that are uniformly distributed with;
The rectangular seam that the tube wall of the noise elimination outer tube 2 and the interior pipe 3 of eliminating the noise has many circles circumferentially to be uniformly distributed with, this seam is a segmented, and bar seam segment length is 8-12mm, and it is 8-12mm that bar seam section and bar stitch intersegmental distance, and rectangular seam stitches wide 0.4-0.6mm for laying vertically;
Streamline cowling 6 is conical, after noise elimination outer tube 2 is connected, becomes bullet-headed.
Air-flow gets into the interior pipe 3 of eliminating the noise by the transfer port on the flange plate 17 earlier, gets into noise elimination outer tube 2 via the seam of the bar on the inner pipe wall 4, via 4 outflows of the seam of the bar on its tube wall, plunders streamline cowling 6 outward again, flows to the gas pipeline downstream.Be evenly equipped with wide seam 4 of 0.5mm vertically around the tube wall of the noise elimination outer tube 2 and the interior pipe 3 of eliminating the noise, the quantity of bar seam 4 is confirmed by the spacing of realization noise elimination effect; Bar seam on each section pipe is segmented, and bar seam segment length is 10mm, and it is 10mm that bar seam section is stitched intersegmental distance with bar.
Wherein the material of silencer is selected 304 stainless steels for use.
The utility model integrated use slit noise elimination, streamline profile rectification noise elimination, expansion chamber eliminate the noise and the multiple noise-cancelling theory of insulating against sound.Can be installed in pipe interior through flange, universal strong is not limited by the valve model, can be used for the aerodynamic noise places such as valve, header and pipeline reducing diameter on the pipeline.
The utility model discloses a kind of natural gas line built-in general-purpose type silencer.Integrated use slit noise elimination, streamline profile rectification noise elimination, expansion chamber eliminate the noise and the multiple noise-cancelling theory of insulating against sound.Can be installed in pipe interior through flange, highly versatile is not limited by the valve model, can be used for the aerodynamic noise places such as valve, header and pipeline reducing diameter on the pipeline.
Practical application shows that this silencer sound deadening capacity greatly, does not influence flow, simple installation, low cost of manufacture.
The utility model can be applicable to the natural gas line Gas Stations, reduces the noise in the field, gas pipeline station, alleviates noise to a station interior able-bodied influence of staff, satisfies the requirement of country to noise circumstance.
