摘　　要：根据形状记忆合金记忆效应的特性实现温度控制阀的设计。控制阀中的驱动弹簧是由N i-Ti合金制成的,它既是感温元件又是控制元件,与偏压弹簧结合共同完成控制过程。形状记忆弹簧感应房间温度的变化而发生形状上的变化,驱动滑块移动,控制热水流量,起到调节房间温度的作用。A temperature control valve was presented according to the memory characteristic of shape memory, alloy. In the temperature control valve, the driver spring is made up of Ni - Ti alloy, it acts as temperature sensor as well as controller, controls the valve together with the press spring. The shape memory alloy changes its shape by the room temperature, drives the valve＇s piston, controls the flux of hot water in the caliduct, and adjusts the room temperature finally.

关 键 词：温度控制阀 形状记忆合金 记忆弹簧
