摘要

用柱状晶CuAlNi形状记忆合金作为感温及控制元件，将其进行定型处理成弹簧，测试了相变温度及回复力.设计制作控温水阀，并对其性能进行测试.结果显示，在进水温度为50~70 ℃的范围内，不同阀芯位置的出水温度分别为38.50、38.75 ℃，调温性能可靠

控温精度为1.50 ℃，误差小.

Abstract

The thermostatic valve was equipped with the spring made of CuAlNi shape memory alloy as the part for sensing and controlling the temperature. For the forming process

the CuAlNi wire was transformed into a SMA spring

whose phase-transition temperature and recovery force were tested. The experimental results of the thermostatic valve show that

with the temperature of in- water ranging from 50 ℃ to 70 ℃

the temperatures of the out-let water at different spool positions are 38.50 ℃ and 38.75 ℃ respectively

and that the thermostatic valve is reliable in controlling the temperature with the margin of error being 1.50 ℃.
