とするという問題があった。When the flow rate of the conventional flow rate control valve 1 is adjusted, a tube is connected to the inflow port 4 after the parts are assembled, and the fluid is actually caused to flow. The flow rate is adjusted by fine adjustment. That is, since the wire 7 made of a shape memory alloy has temperature dependency, its length also changes depending on changes in the operating temperature, the environmental temperature, and the like. Therefore, after assembling parts,
The fluid is actually allowed to flow at the operating temperature range of 10 ° C. and 40 ° C., and the adjustment is performed until the results at both temperatures pass, that is, until the desired amount of fluid flowing out is obtained within the operating temperature range. A repetitive method has been implemented. For this reason, conventionally, there was a problem that it took a very long time to assemble parts and adjust the flow rate.
