「従来の技術」
感温応動素子に形状記憶合金を利用した温度応動弁とし
て1例えば特開昭56−第150680号公報に示すも
のが存在する。``Prior Art'' There is a temperature-responsive valve using a shape memory alloy as a temperature-responsive element, for example, as disclosed in Japanese Patent Application Laid-open No. 150680/1983.

いる。As shown in FIG. 6, this temperature-responsive valve has a valve body 4 which opens and closes a valve port 3 of a valve seat member 2 supported in a main body 1 so as to be movable up and down via a support wall 5. A bias spring 7 for biasing the valve body 4 in the opening direction is installed between the flange 6 fixed to the upper end of the shaft 4a and the upper surface of the support wall 5, and the lower surface of the support wall 5 and the valve body 4 are connected to each other. A compression coil shaped shape memory alloy spring 8 is installed between the heads 4b to extend and bias the valve body 4 in the closing direction.When the inside of the main body 1 is maintained at a high temperature by the passing fluid, As shown in Figure A, the shape memory alloy spring 8 overcomes the spring pressure of the bias spring 7 and expands, lowering the valve body 4-, closing the valve port 3 with the valve head 4b, and conversely inside the main body 1. When the temperature becomes low, the shape memory alloy spring 8 contracts as shown in FIG. .
「発明が解決しようとする問題点」
然し、斯る構造体に於いて、通過流体により高温に維持
される本体1内の温度は、常に一定温度であるとは限ら
ず、内気圧等の関係で形状記憶合金ばねの伸長を必要以
上に促す温度例えば100℃以上の高温となり易い。"Problems to be Solved by the Invention" However, in such a structure, the temperature inside the main body 1, which is maintained at a high temperature by the passing fluid, is not always constant, and due to the influence of internal pressure etc. At this temperature, the temperature tends to be high, for example, 100° C. or more, which promotes the elongation of the shape memory alloy spring more than necessary.
この為、上記従来の温度応動弁にあって、第6図Aに示
すように形状記憶合金ばね8が伸長して弁頭4bで弁口
3を閉塞している状態で、該100℃以上の高温雰囲気
下に晒されると、形状記憶合金ばね8は構造上、支持壁
5と弁頭4b間で伸長中が拘束されているので、形状記
憶合金の特性として該温度に応じて更に伸長しようとし
ても伸長できずに、拘束加熱されることとなる。For this reason, in the above-mentioned conventional temperature-responsive valve, when the shape memory alloy spring 8 is expanded and the valve head 4b closes the valve port 3 as shown in FIG. When exposed to a high temperature atmosphere, the shape memory alloy spring 8 is structurally restrained during expansion between the support wall 5 and the valve head 4b, so as a characteristic of the shape memory alloy, it attempts to further expand in accordance with the temperature. However, it cannot be expanded and is subject to restraint heating.
従って、斯る拘束加熱状態が続いた時は、形状記憶合金
ばね8内体の能力が減衰して、ヘタリを発生させること
となる。このことは、当然に形状記憶合金ばね8の伸縮
能力の低下を意味し、例えバイアスばね7の作用を受け
たとしても、弁口3の開閉能力の低下を起こす原因とな
る。Therefore, when such a restrained heating state continues, the capacity of the inner body of the shape memory alloy spring 8 is attenuated, causing sagging. This naturally means a reduction in the expansion and contraction ability of the shape memory alloy spring 8, which causes a reduction in the opening and closing ability of the valve port 3 even if it is acted upon by the bias spring 7.

上方のみで許容する構成を採用した。``Means for Solving the Problems'' Therefore, the present invention provides that when the shape memory alloy spring is exposed to a high temperature atmosphere of 100° C. or higher for a long time, the elongation ability of the shape memory alloy spring can be enhanced. This was developed with a focus on the ability to effectively prevent the occurrence of fatigue, and in order to release the shape memory alloy spring's ability to expand from its restricted state in a high-temperature atmosphere, a movable ring is moved up and down on the valve stem of the valve body. A coil spring made of a shape memory alloy is installed between the lower surface of the movable ring and the valve seat member that forms the valve opening, and a damper spring is installed between the upper surface of the movable ring and the fixed flange at the upper end of the valve shaft. In addition, a configuration was adopted in which a lowering stopper was formed on the valve stem located below the movable ring, and the movable ring was allowed to move up and down only above the stopper.

うに構成したものである。11□1 Accordingly, in the present invention, the extension force of the shape memory alloy spring in a high temperature atmosphere is reduced by the presence of the damper spring installed between the movable ring whose vertical movement is regulated by the lowering stopper and the fixed collar. 6 "Example" The present invention will be described in detail below based on an illustrative example.
In the temperature-responsive valve according to the first embodiment, as shown in FIG. A spring 8 made of a shape memory alloy is installed between the valve seat members 2 that form a
By attaching a coiled damper spring 11 that can efficiently absorb the stretching force of the shape memory alloy spring 8 between them, and interposing the movable ring 1o that can move up and down the shape memory alloy spring 8, the damper spring 11 is combined. The structure is such that the shape memory alloy spring 8 can be released from the restrained and expanded state at high temperatures.
又、移動リング10の下方に位置する弁軸4a部に、該
移動リング10の降下ストッパー12を形成し、移動リ
ング10の昇降を該ストッパー12の上方のみで許容す
る構成としたものである。Further, a lowering stopper 12 for the movable ring 10 is formed on the valve shaft 4a located below the movable ring 10, and the movable ring 10 is allowed to move up and down only above the stopper 12.

軸4aに固設することにより形成するか、或いは弁軸4
aに直接段部を形成して、該段部をストッパーとして利
用するものとする。Therefore, even if the shape memory base metal spring 8 contracts, the stopper 12 prevents the moving ring 10 from lowering, so the shape memory alloy spring 8 will never receive the spring pressure of the damper spring 11. The lowering stopper 12 may be formed by fixing a separate member to the valve shaft 4a, or may be formed by fixing a separate member to the valve shaft 4a.
A step is formed directly on a, and the step is used as a stopper.

と、同図Bに示す如く今度は形状記憶合金ばね8が伸長
して弁体4を上昇させるので、弁頭4bで弁口3を確実
に閉塞することとなる。Therefore, even in a temperature-responsive valve having such a configuration, when the temperature inside the main body 1 decreases, the shape memory alloy spring 8 contracts as shown in FIG. 3 opens automatically, and conversely, when the inside of the main body 1 becomes high temperature due to the passing fluid, the shape memory alloy spring 8 expands and lifts the valve body 4, as shown in Figure B, so that the valve head 4b This ensures that the valve port 3 is closed.
尚、第2図Aに示す開弁状態にあっては、降下ストッパ

1のばね圧を一切受けず、自身の特性のみで収縮し、又
同図Bに示す通常の閉弁状態にあっては、ダンパーばね
11のはね圧が形状記憶合金ばね8の伸長力に打ち勝っ
ているので。In addition, in the open state shown in FIG.
The damper spring 11 contracts only by its own characteristics without receiving any spring pressure from the damper spring 11, and in the normal closed state shown in FIG. Because I'm overcoming it.
開弁時と同様降下ストッパー12と固定鍔部6間で設定
される取付長さ寸法Hを維持している。The installation length H set between the lowering stopper 12 and the fixed collar 6 is maintained as when the valve is opened.

伸長することが可能となる。即ち、ダンパーばね11は
移動リング10を介して形状記憶合金ばね8の伸長力を
受けて。However, when the main body 1 is placed in a high-temperature atmosphere of 100° C. or higher due to the internal pressure etc. in the above-mentioned normal closed state, the shape memory alloy spring 8 is moved by the damper spring 11 as shown in FIG. Its own elongation force is effectively absorbed, making it possible to elongate further. That is, the damper spring 11 receives the expansion force of the shape memory alloy spring 8 via the moving ring 10.
形状記憶合金ばね8の伸長分αだけ収縮し、高温雰囲気
下での長さ寸法がH−αとなるので、形状記憶合金ばね
8の伸長が可能となる訳である。Since the shape memory alloy spring 8 contracts by the amount of elongation α, and the length dimension under the high temperature atmosphere becomes H−α, the shape memory alloy spring 8 can be expanded.
この結果、高温雰囲気下で長時間使用されても、形状記
憶合金ばね8は従来の如く拘束されたまま加熱されるこ
とがないので、ヘタル心配が全くなくなる。As a result, even if the shape memory alloy spring 8 is used for a long time in a high-temperature atmosphere, the shape memory alloy spring 8 will not be heated while being restrained as in the conventional case, and there will be no fear of damage.

記憶合金ばね8のヘタリ現象をダンパーばね11が吸収
していることを意味する。To explain this point based on the results of an experiment comparing a conventional temperature-responsive valve that does not have the damper spring 11 and the temperature-responsive valve of the first embodiment, it is assumed that the valve closing force, that is, the valve opening 3 caused by the valve body 4
Assuming that the closing force is 2 kg, in a conventional response valve without a damper spring, the valve closing force increases rapidly as the temperature increases, as shown by line A in Figure 3.
It has been found that in the response valve having the damper spring 11, the valve closing force is kept substantially constant even if the temperature rises from around <100° C. as shown by line B in the figure. This means that the damper spring 11 absorbs the fatigue phenomenon of the shape memory alloy spring 8.

A bias spring 7 is attached between corresponding inner wall surfaces of the two.

bで弁口3を確実に閉塞することとなる。Therefore, in the temperature-responsive valve according to the second embodiment, when the temperature inside the main body 1 decreases, the shape memory alloy spring 8 contracts as shown in FIG. 5A, and the spring pressure of the bias spring 7 decreases. is overcome, so the valve body 4 descends and automatically opens the valve port 3. Conversely, when the inside of the main body 1 becomes high in temperature due to the passing fluid, the shape memory alloy spring 8 expands as shown in Figure B. Since the spring pressure of the bias spring 7 is overcome, the valve body 4 rises and the valve head 4
The valve port 3 is reliably closed at step b.

In the closed state shown in FIG. 5B, the spring pressure of the damper spring 11 is equal to the pressure of the shape memory alloy spring 8. Since the stretching force is overcome, the mounting length H is maintained and only the bias spring 7 contracts.

The second embodiment is similar to the first embodiment in that the shape memory alloy spring 8 can be further stretched by using a bias spring 7 to apply an elongation promoting force to the shape memory alloy spring 8. This embodiment is configured to open and close the valve more reliably than in one embodiment.
