An austenitic stainless steel pipe muffler joint and its manufacturing method

Abstract

The invention discloses an austenitic stainless steel pipe muffler joint and a manufacturing method thereof. The other end of the body is connected with an adjustment assembly, and the end of the pipe body close to the fixed pipe section is evenly distributed with silencer holes. The adjustment assembly is used to adjust the opening and closing of the silencer holes. After the adjustment is completed, the adjustment assembly is welded to the pipe body and the fixed pipe section respectively; The method includes: a. preparation before assembly; b. clamping; c. welding; d. removing the muffler to take over. When the present invention installs the muffler connecting pipe, according to the environment in which the muffler connecting pipe is used, the number of closed sound-absorbing holes of the adjusting assembly when focusing on the cooling effect is greater than the number of closing sound-absorbing holes of the adjusting assembly when emphasizing on the effect of noise reduction. According to different occasions, through The adjustment component adjusts the opening and closing of the muffler hole to adjust the focus of the muffler connection, thereby greatly speeding up production efficiency and reducing production costs.

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
