The assembled fan-shaped bracket pieces 21 are installed inside the through hole 121 of the valve body 1, and arc-shaped recessed tanks 211 are respectively formed on the inner peripheral surfaces of the respective arc-shaped pieces 21. A tapered surface 212 is provided at the peripheral surface position. The arc-shaped pieces 21 are gathered and placed in a hollow annular outer envelope with a band 22 that can quickly absorb moisture and soften and decompose instantaneously. The band 22 can be made of a paper material, and the middle portion is twisted to form a columnar shape to add appropriate toughness. Further, the arcuate pieces 21 are surrounded by adhering both ends of the pieces to each other. 24 is wound and extended out of the valve body 1 from the above-described through hole 11.

  As shown in FIGS. 1 to 4, the tensioning device 3 is provided with a support rod 31 inside the safety device 2 in the valve body 1, and a projection 311 is provided on the rod body of the support rod 31 to fit into the introduction tank 131. In addition, two fitting tanks 312 and 312 ′ that are depressed inside are provided to correspond to the accommodation holes 141. The rear end portion of the support rod 31 includes a hemispherical portion 315 and an elastic part 33, and a pressure adjusting member that biases the support rod 31 is provided.

Is provided to prevent gas from entering the valve body 1. A piercing portion 411 having a slightly smaller diameter is provided at one end of the needle portion 41, corresponding to the end opening of the compression cylinder 50, and the piercing portion 411 is installed by covering the elastic part 42 and the hollow fixing ring 43. The fixing ring 43 is connected to the inner peripheral surface of the storage hole 141 to serve as a support part for the elastic part 42, and the elastic part 42 continuously urges the ball 44 provided at the tip of the other end of the needle part 41. ing. As a result, the ball 44 is fitted in the insertion tank 312 of the support rod 31, and the needle portion 41 is pressed down by the ball 44 due to the axial movement of the support rod 31, and the puncture portion 411 compresses the compression cylinder. Break through 50 ends.

  The valve device for a compression cylinder according to the present invention is such that the band 22 of the safety device 2 is broken by the string 24 or softens itself by touching moisture by the above-described valve body 1, the safety device 2, the tension device 3 and the breaking device 4. When the plurality of arc-shaped pieces 21 are spread apart, the support bar 31 is pushed forward in the axial direction by the elastic part 33 of the pressure adjusting member and moves to act on the breakthrough device 4.

  6 and 7 show an embodiment of a compression cylinder valve device according to the present invention.

  The embodiment of the present invention can be used by joining the exhaust hole 142 of the valve body 1 to a water lifesaving device (life jacket, lifebuoy), an air mat, an airplane lifesaving equipment, and the like.

  When there is no need for use, the plurality of arc-shaped pieces 21 prevent the support rod 31 from moving forward, so that the needle portion 41 does not break through the end opening of the compression cylinder 50 (see FIG. 4).

  However, when necessary, when the user pulls the above-described string 24, the band 22 is simultaneously torn (see FIG. 6), and the elastic part 33 of the pressure adjusting member moves the support bar 31 forward. Thus, the plurality of arc-shaped pieces 21 are pushed open by the tapered portion 313 at the front end portion of the support rod 31. As a result, the support bar 31 is moved further forward in the axial direction, and the ball 44 at the upper end of the needle portion 41 leaves the fitting tank 312, and simultaneously pushes the needle portion 41 downward to break through the end opening of the compression cylinder 50. When the support bar 31 continues to move forward, the ball 44 rises again and is fitted into another insertion tank 312 '(see FIG. 7), and the needle portion 41 rises again and returns to its original position. Thereby, the gas inside the compression cylinder 50 is leaked, and the gas is filled into the equipment via the storage hole 141 and the exhaust hole 142, so that an arbitrary operation function by the user can be obtained.

  Further, when the user cannot operate the compression cylinder valve device according to the present invention, or when it is not enough to operate the string 24 to break through the end of the compression cylinder 50, water is supplied to the valve body 1 through the through hole 121. By making it approach, the band 22 gets wet and softens, and the arc-shaped pieces 21 are pushed and opened by the elasticity of the support bar 31. Thereby, since the support bar 31 moves forward and the needle portion 41 is moved by the ball 44 at the same time, a function corresponding to an emergency can be obtained by automatically operating in a timely manner.

  As described above, the compression cylinder valve device of the present invention surely has practicality and creativity, the operation of the means is novel, the effect and the design purpose match, and the rational and Because of its progressive nature, we apply here for utility model registration under the law.
