Abstract
The invention discloses an air suction pipe of a liquid accumulator of a compressor and a liquid accumulator comprising the air suction pipe. The air suction pipe is in an F shape and is composed of an inner iron or stainless steel air suction pipe body and two outer copper air suction pipe bodies with two output branches. The outer copper air suction pipe bodies are fixedly welded to the inner iron or stainless steel air suction pipe body. The melting temperature of a weld pass of the air suction pipe is over 50 DEG C higher than the subsequent weld temperature between the air suction pipe welded and the compressor. The air suction pipe is designed in the F shape, so that a double-air-suction pipe structure is formed, the liquid accumulator is easy to assemble, and cost is lowered. The two outer copper air suction pipe bodies are communicated with the compressor and welded to the compressor, flame welding must be adopted when the copper air suction pipe bodies are welded to the compressor, and therefore in order to prevent the situation that high temperature generated in flame welding is conducted to the weld pass for welding the outer copper air suction pipe bodies to the inner iron or stainless steel air suction pipe body, and then the weld pass is molten and leaking gas, the melting temperature of the weld pass of the air suction pipe is raised. In this way, the reliability of the air suction pipe is guaranteed.
