Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of silencers, in particular to a multi-channel noise reduction silencer. BACKGROUND

[0002] Silencers are widely used in various industrial and civil fields, such as air conditioners, fans, air compressors, etc. In these devices, silencers can reduce noise pollution, improve the quality of the working environment and production efficiency. Silencers are mostly made of copper powder by pressure casting and sintering. The gaps between the copper powders are used to disperse and circulate the gas, thereby reducing the flow rate of the exhaust gas to achieve the effect of silencing. The silencer includes a silencer body, a nut, and an externally threaded pipe. The nut and the externally threaded pipe are integrally arranged. The silencer body is fixed in the nut and the externally threaded pipe by pressure casting. The outer end of the silencer body has a transverse groove. A screwdriver can be used to rotate the silencer through the transverse groove, so that the silencer can be installed in a narrow space where a wrench cannot be used to operate the nut. Since the silencer body is fixed between the nut and the externally threaded pipe by pressure casting, the stability between the silencer body and the nut and the externally threaded pipe is low. In addition, during use, the wind force in the pipeline will impact the silencer body, causing the silencer body to loosen. CONTENT OF THE UTILITY MODEL
