Description
Technical Field
The utility model relates to a tool device for welding an expansion valve, and belongs to the technical field of expansion valve machining tools.
Background
An expansion valve is an important component in a refrigeration system and is typically mounted between the reservoir and the evaporator. The expansion valve enables the medium-temperature high-pressure liquid refrigerant to be low-temperature low-pressure wet steam through throttling, then the refrigerant absorbs heat in the evaporator to achieve the refrigeration effect, and the expansion valve controls the flow of the valve through the change of the superheat degree of the tail end of the evaporator to prevent the phenomena of insufficient utilization of the area of the evaporator and cylinder knocking. In order to prevent the valve body of the expansion valve from being clogged, a filter is generally installed at the front end of the expansion valve, and the expansion valve and the filter are connected by a copper pipe. At present, when a copper pipe between an expansion valve and a filter is welded, the positions of the expansion valve, the filter and the copper pipe can only be fixed manually, so that the working efficiency is low and the labor intensity is high.
Therefore, how to provide a tool device for welding the expansion valve is the research object of the utility model.
