Abstract
The utility model relates to an air compressor exhaust pipe silencer, which comprises an expand node 1 and a flexible metal node 2. The expand node is provided with a gas inlet 3 and a broadened cavity 4. When pulsative airflow with aerodynamic noise flows across the broadened cavity by the inlet, the peak value of the airflow pulsation can be lowered, the impact energy of the airflow for pipelines is reduced, the noise reduction is realized by reducing the vibration of the pipelines, and partial aerodynamic noise can be eliminated because of gas expansion; the flexible metal node can reduce the vibration of the pipelines caused by gas shock and the vibration of the body of the compressor to reduce noise. The utility model has the advantages of good effect, simple structure, and convenient installation and operation. The designated figure 1 is the summarization figure.
Description
The utility model is used for air compressor row (sending) feed channel and eliminates the noise.
Present air compressor is in installation, when using, the blue dish of its relief opening common usage is connected with row's (sending) feed channel rigidly, during compressor operating, because the continuous impulse piping of sending of pulse pneumatic, and the vibration of compressor fuselage also influences pipeline, causes pipe vibration and produces vibration noise; The eddy current of pressurized gas or mixed flow then produce aerodynamic noise.These noises seriously influence environment.
The utility model provides a kind of air compressor outlet pipe silencing apparatus, and this silencing apparatus can reduce the vibration noise and the aerodynamic noise of row's (sending) feed channel.
Technological scheme is as follows:
Fig. 1 is a schematic structure diagram, and Fig. 2 is embodiment's schematic structure diagram.
The utility model is by dilating joint 1 and flexible metal joint 2 forms, and dilating has gas feed 3 and expand chamber 4 on the joint 1, described dilate joint be connected with the flexible metal connect after, both passages are continuous, there is gas vent 5 flexible metal on saving. The gas that contains aerodynamic noise is entered by import department and expands the chamber, by volumetric expansion flow pulsation reduction peak value, reduce the pulsation air-flow to the impact of pipeline, reach the purpose that reduces the pipe vibration noise, in addition, gas can be eliminated the part aerodynamic noise through dilating also; Flexible metal joint is set reduces the pipe vibration that causes because of gas impact and compressor body vibration, to reduce vibration noise.
The utility model is to expand chamber expansion flow pulsation reduction peak value, reduce the gas amount and to reduce the vibration of education and correction for juvenile offenders road with the flexible metal, aerodynamic noise and pipeline vibration noise have effectively been reduced, can reduce noise 5～10dB(A), simple in structure, easy to install.
Embodiment.Embodiment is by structure fabrication shown in Figure 2, and the carbon steel corrugated expansion joint that the flexible metal joint adopts market to buy also can adopt metallic hose.Expansion joint is withstand voltage, compensation rate is bigger, and shockproof function is arranged.Present embodiment dilates joint 6 in the outlet termination of flexible metal joint, and from overall structure, joint two ends, flexible metal all connect and dilate joint, pulse pneumatic is successively flowed through two and is dilated joint, more effectively to reduce the gas peak value, reduce the pulsatile impact energy of air-flow to pipeline, reduce vibration noise.Dilate joint and be carbon steel material.Expansion chamber diameter is 2:1 with the ratio of inlet diameter.
The utility model also can be used for the gas path pipe of other equipment and eliminates the noise.
Claims (2)
1, air compressor row (sending) gas-pipe muffler, it is characterized in that forming by dilating joint 1 and flexible metal joint 2, dilating joint has gas inlet 3 on 1 and expands chamber 4, on the joint of flexible metal gas outlet 5 is arranged, and describedly dilates joint and flexible metal joint to be connected both passages of back continuous.
