However, due to the shape memory alloy material, when the ambient temperature reaches the set temperature, the valve closing spring 17
The valve body 15 expands against the spring force and operates to push down the valve body 15 and open the gas port 8. However, when the surrounding temperature decreases and the temperature is cooled to below the set temperature again, the valve body 15 returns to its original state. It is made of reciprocating shape memory material that stops the button from being pressed down. Reference numeral 21 indicates a communication port that communicates with the gas vent 8 and the side passage 11, and 22 indicates a pressure spring that presses the lower stem portion 13 upward.

ガス通口８を閉じ、ガスの放出を停止する。(Function) When a gas cylinder having the following configuration is placed under a set heating condition, the valve opening spring 20 deforms to open the gas port 8. That is, as shown in the left half of FIG. 3, when the set temperature is reached, the valve opening spring 20 returns to its memorized shape, and the entire valve expands, causing the valve body 15 engaged at its lower end to resist the elasticity of the valve closing spring 17. By pressing down, the gas port 8 is opened, and the siphon pipe 14,
Side passage 11, communication port 21, gas vent 8, discharge port 4a
Release more gas to the outside of the vessel. Note that during normal use, the stem rubber 5 is pushed in and only the gas passage 7 is opened in the state shown in the right half of FIG. 3. Furthermore, when the gas is released, the temperature inside the container body 1 decreases due to latent heat of vaporization, and when the temperature drops below a certain level, the valve opening spring 20 contracts, so the valve body 15 closes the gas vent 8 again by the seat 18. Close and stop releasing gas.

効果が得られる。(Effects) Therefore, according to the present invention, even if a gas cylinder or the like is heated by being thrown into a fire, when the set temperature is reached, the valve opening spring extends, pushes down the stem, opens the gas vent, and removes the remaining gas. Release gas. Therefore, it is safe because there is no risk of explosion, and moreover, it returns to its normal state when the temperature drops, so it can be reused in the case of instantaneous activation due to abnormal use.
