[0002] The main function of the silencer is to reduce and lower the noise generated by the equipment during operation and to improve the silencing effect of the equipment. Specifically, the silencer reduces and attenuates the sound energy generated by the noise source through reflection, interference, absorption, etc. of the internal structure, thereby achieving the purpose of reducing noise. In the prior art, air ports are set at both ends of the silencer, and the air ports are used for air intake or air outlet. A copper sleeve is welded in the air port. In order for the copper sleeve to better support and fix the air port, the depth of the copper sleeve entering the air port needs to reach a certain length, such as 6mm. In the case where the copper sleeve needs to be manually pressed into the air port, the depth can only be controlled based on estimation, which will result in a large error. Therefore, the utility model proposes a pipe silencer. Utility Model Content
