Abstract

The invention belongs to the technical field of mechanical equipment silencing, and particularly relates to a silencer of a microtype gas thruster. The silencer is mainly used for solving the problem that an existing microtype gas thruster is likely to cause air pollution and noise pollution and damage adjacent equipment and devices. According to the adopted technical scheme, the silencer of the microtype gas thruster comprises a base and a top cover, and further comprises a first silencing ring, a second silencing ring, an outer circle shell, a fixing ring and a silencing material, the base is in threaded connection with the lower end of the microtype gas thruster, the first silencing ring, the second silencing ring and the outer circle shell are sequentially arranged on the periphery of the microtype gas thruster, the lower ends of the the first silencing ring, the second silencing ring and the outer circle shell make contact with the base, the space between the first silencing ring and the second silencing ring and the space between the second silencing ring and the outer circle shell are filled with the silencing material, and the top cover and the upper end of the microtype gas thruster are in threaded connection. The silencer of the microtype gas thruster has the advantages of being good in silencing effect and long in service life.

Description

technical field [0001] The invention belongs to the technical field of noise reduction for mechanical equipment, in particular to a noise reduction device for a miniature gas propeller. Background technique [0002] The in-line miniature gas thruster is to ignite and trigger the propellant to push the components to do work. After the propulsion is completed, the high-temperature gas from the propellant combustion will form a shock wave and be discharged into the atmosphere, producing explosions and smoke, causing air pollution and noise pollution. , which needs to be denoised. No muffler is arranged on the existing miniature gas thruster, which is easy to cause damage to adjacent equipment and components. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, to provide a miniature gas thruster noise reduction device, to solve the problem of air pollution, noise pollution and easy damage to adjacent equipm...
