Document Type and Number:
WIPO Patent Application WO/2024/063145
Kind Code:
A1
Abstract:
Provided are a valve device, an expansion valve, a method for manufacturing a valve device, and a method for manufacturing an expansion valve with which manufacturing costs can be reduced without increasing the number of manufacturing processes. A valve device of a valve main body includes a base surface portion which is a flat surface that is formed by subjecting one side surface of the valve main body to a prescribed cutting process or grinding process, and to which an object to be fixed can be attached, and an adjacent portion adjacent to at least a portion of an edge of the base surface portion, wherein the adjacent portion is not subjected to the prescribed cutting process or grinding process, and has a shape that does not project relative to the base surface portion in a normal line direction of the base surface portion. By having such a valve main body, the amount of material that is cut and discarded during processing is reduced, and since burrs are not formed between the base surface portion and the adjacent portion, a process to remove burrs is not required, and there is thus no increase in the number of processes.
