Austenitic stainless steel pipe silencer connecting pipe and manufacturing method thereof

Abstract

The invention discloses an austenitic stainless steel pipe silencer connecting pipe and a manufacturing method thereof. The austenitic stainless steel pipe silencer connecting pipe comprises a pipe body, an air inlet pipe segment, and a fixed pipe segment. The pipe body is in an irregular pipe shape. The air inlet pipe segment is welded to one end of the pipe body, and an adjusting assembly is connected between the fixed pipe segment and the other end of the pipe body. Sound attenuation holes are evenly distributed in the end, closed to the fixed pipe segment, of the pipe body. The adjusting assembly is used for adjusting opening and closing of the sound attenuation holes. After the adjusting assembly completes adjusting, the adjusting assembly is welded to the pipe body and the fixed pipesegment. The method comprises the steps that a, preparations are made before assembling; b, clamping is carried out; c, welding is carried out; and d, the silencer connecting pipe is taken down. Whenthe silencer connecting pipe is mounted, according to the environment where the silencer connecting pipe is used, the number of the sound attenuation holes closed by the adjusting assembly when usersput particular emphasis on the refrigeration effect is larger than the number of the sound attenuation holes closed by the adjusting assembly when users put particular emphasis on the noise reductioneffect, the emphasis of the silencer can be adjusted by adjusting opening and closing of the sound attenuation holes through the adjusting assembly according to different occasions, and therefore production efficiency is greatly improved, and production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of muffler equipment, and in particular relates to an austenitic stainless steel pipe muffler joint and a manufacturing method thereof. Background technique [0002] The muffler is a basic component in the refrigeration system. In the system, the airflow can be buffered through the cavity to effectively reduce the noise, and it can also store the excess refrigerant in the system. There are many types of mufflers, but the muffler mechanism can be divided into six main types, namely resistive muffler, resistive muffler, impedance composite muffler, micro-perforated plate muffler, small hole muffler and active muffler. [0003] In the prior art, the high-pressure gas is discharged into the muffler through the muffler joint, and the flow rate of the high-pressure gas is reduced through the muffler hole on the muffler joint, thereby slowing down the flow rate of the gas discharged from the muffler, thereby reduci...

Problems solved by technology

[0003] In the prior art, the high-pressure gas is discharged into the muffler through the muffler joint, and the flow rate of the high-pressure gas is reduced through the muffler hole on the muffler joint, thereby slowing down the flow rate of the gas discharged from the muffler, thereby reducing the noise However, blindly pursuing the effect of noise reduction will often lead to a reduction in the cooling effect of the refrigeration system. Therefore, in the refrigeration system used in different occasions, the emphasis between noise reduction and refrigeration is often different. For this In one case, it is necessary to process muffler pipes with different numbers of holes, which greatly reduces production efficiency and increases production costs; during the manufacturing process of muffler pipes, due to installation requirements, the pipe body of the muffler pipes is irregular, resulting in When the connecting tube is welded on the welding table, it is easy to shake, which reduces the welding quality
