【発明の詳細な説明】
〔発明の技術分野〕
この発明は流体の温度変化によって弁が自動的に開閉す
るようにした弁装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a valve device in which a valve automatically opens and closes depending on changes in fluid temperature.
従来の弁装置は流体の温度を感知する装置と弁を開閉さ
せる制御弁とを組合せていたので、制御機構が複雑で大
きくなった。また制御機構が複雑であるので、信頼性・

〔発明の概要〕
この発明はこのような従来のものの欠点を解消するため
になされたもので、形状記憶合金と弾性体とによって弁

すると共に流体洩れをなくした弁装置金提供する。Conventional valve devices combined a device that senses the temperature of the fluid with a control valve that opens and closes the valve, resulting in a complicated and large control mechanism. In addition, since the control mechanism is complex, reliability and
There were shortcomings in terms of life, etc., and there was a risk of fluid leakage. [Summary of the Invention] This invention was made to eliminate these drawbacks of the conventional valve. By configuring the valve device to operate, a valve device is provided which is completely simple in construction and eliminates fluid leakage.

する。The figure shows one implementation of the invention. In the figure, +13 is a cylindrical body forming a fluid flow path, and is provided with a valve seat (ia) and first and second locking parts (lb) (lc). (2) is a cylindrical body (7 langes for connecting to an 11t" container +31 +41, etc.), (5) is a valve arranged so that it can come into contact with the valve seat (la), and what is the engagement part (6a) used for? Operation stick (
6) is solidified at the tip. (7) is the eighth locking part (
10) and the engaging part (6&), (8) is the first engaging part ('b) and the engaging part 5
(6a) is an elastic body that presses the shape memory alloy (7) and is composed of a coil spring. Now, if the temperature of the fluid in the first container (4) is high, When the temperature of the fluid surrounding the shape memory alloy (7) reaches a preset value, the shape memory alloy (7) expands and the valve +5) located at the position indicated by the broken line comes into contact with the valve seat. All fluid flow from the first container (4) to the eighth container (3) is blocked.

を開く。The temperature inside the first container (4) decreases and the shape memory alloy (7)
), the elastic body (8) compressively deforms the shape memory alloy (7)' and moves the valve (5) to the position shown by the broken line, thereby closing the valve (5). 5)

なお、上記説明は流体の温度が高い時に弁を閉じるもの
について説明したが、弁座（ｌｃンを弁（５）よりもば
ね（８）側に設けることによって、流体の温度が低くな
った時に弁を閉じるように構成することができる。In addition, the above explanation was about closing the valve when the temperature of the fluid is high, but by providing the valve seat (LC) closer to the spring (8) than the valve (5), it can be closed when the temperature of the fluid becomes low. The valve can be configured to close.
また、温度特性の異った形状記憶合金を選択することに
よって、任意の流体温度で弁を開閉することが可能であ
る。Furthermore, by selecting shape memory alloys with different temperature characteristics, it is possible to open and close the valve at any fluid temperature.
以上のようにこの発明によると、形状記憶合金と弾性体
によって弁を操作するように構成したので、構成が簡単
となり、弁を外部から操作する必要がないので、流体が
洩れる恐れがない。As described above, according to the present invention, the valve is configured to be operated using a shape memory alloy and an elastic body, so the configuration is simple, and there is no need to operate the valve from the outside, so there is no risk of fluid leakage.
