Abstract: PURPOSE: An automatic temperature detectable opening and closing valve using a shape memory alloy wire and a valve opening and closing method are provided to supply hot water to a hot water supply facility without additional electrical facilities because a path is opened and closed by a shape memory alloy wire varying according to the temperature of fluid. CONSTITUTION: An automatic temperature detectable opening and closing valve comprises a body(110), an elastic spring(121), and a blocking member. The body comprises a chamber with an inlet and an outlet. The elastic spring is formed by a shape memory alloy and is flexibly changed while contacting to fluid flowing into the chamber. When the temperature of the fluid is reached at a predetermined temperature, the elastic spring is contracted. When the temperature is less than the predetermined temperature, the elastic spring is expanded. The blocking member opens the outlet of the chamber when the elastic spring is contracted, and closes the outlet of the chamber when the elastic spring is expanded.

Abstract translation: 目的：提供一种使用形状记忆合金线和阀门打开和关闭方法的自动温度检测开关阀，以便在没有附加电气设施的情况下向热水供应设施供应热水，因为路径被形状记忆打开和关闭 合金线根据流体的温度而变化。 构成：自动温度检测开闭阀包括主体（110），弹性弹簧（121）和阻挡构件。 主体包括具有入口和出口的室。 弹性弹簧由形状记忆合金形成，并且在与流入腔室的流体接触时灵活地改变。 当达到预定温度的流体温度时，弹性弹簧收缩。 当温度低于预定温度时，弹性弹簧膨胀。 当弹性弹簧收缩时，阻挡构件打开腔室的出口，并且当弹性弹簧膨胀时封闭腔室的出口。

Abstract: PURPOSE: A power switch using a memory alloy is provided to be usable semi-permanently for overheating or over-current by utilizing a power switch using a memory alloy. CONSTITUTION: A power switch(10) includes a switch terminal(100) and an open/close unit(200). The switch terminal is turned on or off to supply or block currents. The open/close unit is connected to the switch terminal and supplies or blocks currents. The open/close unit includes a memory alloy component(210) and an elastic unit(220). The memory alloy component is formed in a spring shape, placed in the power switch, and controls the operation of the switch terminal with the properties of a memory alloy. One end of the elastic unit is combined with the memory alloy component, and the other end is combined with the switch terminal. The memory alloy component detects the temperature of the inside and gets a specific amount of deformation when the temperature reaches a specific temperature. The elastic unit performs elastic motion in order to enable the memory alloy component to be connected to the switch terminal.
