Abstract

Abstract: Thispaperintroducesa valve which useshape memory alloys( SMA) fortemperaturecon trol, which makes useof deformation of SMAcaused by variation oftemperaturetocontrolmechanical parts. Thevalvecan beswitched on or off automatically and hasthe advantages ofsimplestructureand reliable performance.Itcan beusedin adverse workingconditionsor conditions with lower requirementson controlling precision ofthetemperatures. Consequent ly,it hasextensive application prospects.

Key words: shape memory alloy, valve, thermomechamicalstability
