Steam and liquid separator for air conditioner and its producing method

Abstract

Separator for steam and liquid includes exhaust pipe, mounting plate, air inlet pipe, filter, and barrel characters are that both exhaust pipe and air inlet pipe are prepared from iron pipe. Advantages are: reasonable structure, lowering production cost, no lap joint in one whole iron pipe, no welding line. Procedure for welding exhaust pipe, air inlet pipe and up barrel is changed to about 1130 deg.C furnace brazing under protective atmosphere from flame weld. Advantages of the procedure are: simplified operation technique, fine welding line, high weld strength, good air-tightness, and no pile of solder. Protection weld of CO2 gas is adopted for welding between up barrel and low barrel. Then, tube end expansion is carried out for exhaust pipe, and air inlet pipe so as to guarantee reasonable assembly technique.

Description

technical field

[0001] The invention relates to a method for manufacturing a gas-liquid separator, in particular to a method for manufacturing a gas-liquid separator for an air conditioner. Background technique

[0002] The vapor-liquid separator that adopts on the existing air conditioner, exhaust pipe and air intake pipe in it all all adopt copper pipe to make. And because the price of copper is higher, especially the recent soaring price of international copper, so the cost of gas-liquid separator is increased, thereby increasing the manufacturing cost of the air conditioner. Contents of the invention

[0003] The purpose of the present invention is to provide a simple and reasonable structure, the intake pipe and exhaust pipe are all made of iron pipes, the manufacturing process is simple, the cost can be greatly reduced, a reliable and durable manufacturing method of a gas-liquid separator for air conditioners.

[0004] The purpose of the present invention can be ach...
