Problems solved by technology
[0002] At present, most of the air inlet and outlet pipes of the existing compressor liquid accumulator are whole copper pipes, which are usually connected with the shell of the liquid accumulator by flame brazing or high frequency brazing with silver solder. The silver solder is not only expensive, but also In the production process, a large amount of carbon dioxide is generated to pollute the environment, and the extensive use of copper pipes further increases the production cost

Embodiment Construction
[0028] The present invention is further described in conjunction with the following examples.
[0029] A liquid reservoir inlet and outlet pipe, such as figure 1 , figure 2 and image 3 As shown, it includes an air inlet pipe 1 and an air outlet pipe 2 , the air inlet pipe 1 is arranged on the upper part of the liquid reservoir 3 , and the air outlet pipe 2 is arranged on the lower part of the liquid reservoir 3 . The intake pipe 1 comprises a first intake pipe 4 and a second intake pipe 5, in the butt end of the first intake pipe 4 and the butt end of the second intake pipe 5, the inner diameter of one of the butt ends is smaller than the outer diameter of the other end, the second An air inlet pipe 5 is a copper pipe or a copper-plated pipe, and the second air inlet pipe 5 is any one of an iron pipe, a copper-plated pipe and a copper pipe. Preferably, the second air inlet pipe 5 is an iron pipe; One air outlet pipe 6 and the second air outlet pipe 7, in the butt end of t...

The invention relates to the field of a compressor, in particular to a liquid reservoir air inlet and outlet pipe and a manufacturing method as well as application thereof. The liquid reservoir air inlet and outlet pipe comprises an air inlet pipe and an air outlet pipe, wherein the air inlet pipe is arranged on the upper part of a liquid reservoir; the air outlet pipe is arranged on the lower part of the liquid reservoir; the air inlet pipe comprises a first air inlet pipe and a second air inlet pipe; the first air inlet pipe and the second air inlet pipe are butt-welded through flash welding; the air outlet pipe comprises a first air outlet pipe and a second air outlet pipe; and the first air outlet pipe and the second air outlet pipe are butt-welded through flash welding. By using the liquid reservoir air inlet and outlet pipe of the structure, the using amount of copper is saved, and the manufacturing cost is reduced; and butting ends of two pipe sections of the air inlet pipe, and butting ends of two pipe sections of the air outlet pipe can be directly butt-welded respectively and can be welded again without socket connection, so that the liquid reservoir air inlet and outlet pipe can be designed into a simpler structure, the welding quality is high, and the service life is prolonged.
Description
technical field [0001] The invention relates to the field of compressors, in particular to an air inlet and outlet pipe of a liquid accumulator and its application. Background technique [0002] At present, most of the air inlet and outlet pipes of the existing compressor liquid accumulator are whole copper pipes, which are usually connected with the shell of the liquid accumulator by flame brazing or high frequency brazing with silver solder. The silver solder is not only expensive, but also In the production process, a large amount of carbon dioxide is produced to pollute the environment, and the extensive use of copper pipes further increases the production cost. [0003] In the case of increasingly serious environmental pollution, there is an urgent need for an environmentally friendly production process and low manufacturing cost of the accumulator inlet and outlet air pipes, so as to relieve the cost pressure of compressor manufacturers.
