Welding system for ball valve of refrigerating system

Abstract

The invention relates to a welding system for a ball valve of a refrigerating system. The welding system comprises a welding base, a welding turntable is mounted on the upper end surface of the welding base, the welding turntable is driven to rotate by a welding motor mounted on the welding base, a plurality of workpiece placing seats are distributed on the upper end surface of the welding turntable in parallel in the circumferential direction of the welding turntable, and a feeding area, a preheating area, a welding area, a cooling area and a discharging area are sequentially distributed on the welding base in the rotating direction of the welding turntable. The welding system has the advantages that the welding base and the welding turntable are matched to serve as a conveying basis, in cooperation whit arrangement of different areas including the feeding area, the preheating area, the welding area, the cooling area and the discharging area, automatic welding of a valve body, a valve deck and a copper connecting pipe and assembly line type continuous welding production are achieved, manual welding is not needed, the labor intensity of workers is greatly reduced, the stability of the welding quality is ensured, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a welding system for a refrigeration system ball valve. Background technique [0002] A system that uses external energy to transfer heat from a lower-temperature substance (or environment) to a higher-temperature substance (or environment) is called a refrigeration system. The refrigeration system consists of a refrigerant and four major components, namely a compressor, a condenser, Expansion valve, evaporator. [0003] The compressor is the driving force of the refrigeration cycle. It is driven by the motor and rotates continuously. In addition to timely extracting the vapor in the evaporator to maintain low temperature and low pressure, it also increases the pressure and temperature of the refrigerant vapor through compression to create a refrigerant. The condition under which the heat of vapor is transferred to the external environment medium. That is, the low-tempera...

Problems solved by technology

During the processing of the above-mentioned ball valve, it is necessary to weld and fix the valve body 1 and the first copper connecting pipe 3, the valve cover 2 and the second copper connecting pipe 4, and then screw the valve body 1 and the valve cover 2, So as to form a whole, while the traditional welding method adopts the manual welding method, the labor intensity is relatively high, and only one workpiece can be welded at a time, the whole welding process cannot realize continuous production, and the work efficiency is not high. , during manual welding, the quality of welding will be artificially affected, and the welding quality is unstable
