Abstract

PURPOSE:To make a valve open in the case of overheating so as to avoid the danger of explosion by providing a releasing device made of shape-memory alloy of which the outer edge is fixed to a valve mechanism and the inner edge is attached to a stem in such a manner as to be movable in the axial directions of the stem and by forming on the outer surface of the stem a catch engaging the releasing device for pushing in the stem at the time of abnormality. CONSTITUTION:When the vessel is heated to a specified temperature, a releasing device 15 undergoes deformation into a shape in memory, which acts on a stepped catch 23 engaging the inner part 17 of the releasing device 15 in such a manner as to push a stem 7 into the main body. As a result, a valve mechanism opens and releases gas, such as LPG, contained in the vessel 1. The setup is restored to its normal state when the heating stops and the temperature falls below the specified point. When the stem 7 is pushed in from its projecting position during the normal use, the stem 7 moves inward in contact with a stem rubber 9 and a closing spring 13 but the gas is delivered normally, since the releasing device 15 is not affected by the deformation of the stem rubber 9. Therefore, an improvement can be achieved in safety and practicality.

The first example is shown in FIG.
5, the outer part 16 is located between the mounting notch 18 formed on the upper end surface of the stem rubber 9 supporting the stem 7 and the inner end 6a of the holding cylinder part 6 which corresponds to the end of the container body 1. A hollow space 19 is formed in the stem rubber 9 held and inside the opening member 15 to allow the opening member 15 to deform. On the other hand, the inner part 17 of the opening member 15 engages with an engaging part 20 formed in a step shape on the outer surface of the stem 7. When the opening member 15 is brought into contact with the inner end 6a as in this example, the deformation force generated in the opening member 15 at the set temperature is backed up by the inner end 6a, which is convenient for pushing the stem 7 into the upper rod.

This is an example in which the opening member 15 is provided in the valve chamber that is downwardly away from the rubber 9. Since there is sufficient space at the installation site, it is easy to assemble the opening member 15, and there are spaces 21.
22, there is no need to provide a space for it as in the previous example. The outer part 16 of the opening member 15 is embedded in the inner wall of the housing, and the inner part 17 engages with a stepped engagement part 23 formed on the outer surface of the stem on the inner side of the gas passage 11.

The opening member 15 has a ring shape with a hole 24 in the center through which the stem 7 passes, and the inner part 17 is connected to the outer part 1 at a set temperature.
It is formed of a metal material that has a memorized shape that deforms in the stem axis direction relative to the stem. Fig. 5(a) shows an example of the opening member 15, which is a ring-shaped object that deforms into a forest shape when heated, and Fig. 5(b) shows another example, in which a part of the ring is broken like a C-washer. When heated, the inner end portion 17 deforms so as to relatively protrude to both sides in the axial direction.

(Function) When the container of the present invention configured as described above is heated for some reason and reaches the set temperature, the opening member 15 deforms into the memorized shape and the stepped engagement at the inner part 17 is performed. Since the stem 7 is pushed into the main body at portions 20 and 23, the valve mechanism opens and the gas such as LPG filled inside the container main body 1 is released.

(Effects) Therefore, when the small pressure vessel of the present invention is heated and reaches the set temperature, the opening member formed by the shape memory material deforms, directly moves the stem at its free end, and the valve mechanism immediately opens, causing a fire. There is no risk of explosion even if the product is dumped inside, and it will return to its original state once the temperature drops below the set temperature.
It exhibits remarkable effects such as high safety and practicality.
