Abstract

The invention provides a silencing absorber. The silencing absorber comprises a cylinder, a left seal head and a right seal head arranged at two ends of the cylinder, an air inlet pipe arranged on thecylinder and an air outlet pipe arranged on the right seal head. The silencing absorber also comprises a pressure regulating device which is arranged at the air inlet pipe and is located in the cylinder; the pressure regulating device comprises a straight pipe, a connecting rod, a limiting sleeve, a spring, a valve core and an end cap. The straight pipe is arranged at the tail end of the cylinder, the connecting rod is fixed to the straight pipe, the limiting sleeve is fixed to the straight pipe through the connecting rod, the spring is arranged on the limiting sleeve, a part of the valve core is located in a guiding cavity of the limiting sleeve while the other part of the valve core is connected to the end cap; and the end cap leans against the edge of the straight pipe. By adopting thestructure, the silencing absorber provided by the invention is good in silencing and absorbing effects.

Description

technical field [0001] The invention relates to the manufacture of mechanical parts, in particular to a sound damper and shock absorber. Background technique [0002] When the water-cooled unit is working, because the high-pressure gas discharged from the compressor exhaust port will generate a strong pulse, if the energy of the strong pulse is not weakened, it will definitely cause huge noise pollution and vibration, so long-term exposure to such noise pollution and Vibration-polluted staff will inevitably suffer from various physical symptoms. This kind of noise pollution and vibration pollution not only harms the health of the staff, but also endangers the health of nearby residents, and the huge vibration generated by the powerful pulse is also harmful. It will cause the breakage of the pipeline, thereby reducing the life of the equipment. [0003] Chinese patent CN 102418686 A discloses a noise damper. The noise damper includes a cylinder, a front head, a rear head, a ...
