Document Type and Number:
Japanese Patent JP2018141476
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide series of several kinds of pressure suppression safety devices for use in preventing poor fusion caused by increasing in pressure of a closed space formed inside by integrally and systematically closing opening ports at EF joints, and along with this provision, to provide series of EF joints for use in installing series of pressure restriction safety devices.SOLUTION: This invention relates to a pressure restriction safety device having lean negative pressure atmosphere in it or vacuum. In regard to the kind in which a main body of the pressure restriction safety device has a cut-line and the kind in which no cut-line is provided and a capsule type and in regard to the kinds, a pressure restriction safety device having material quality of synthetic resin, glass, paper and complex material or the like cracked in which a crack is generated at a main body upon reaching to a set pressure, and there is provided, as means, a pressure restriction safety device showing no crack and having no cracked synthetic resin or thin metal or shape memory alloy or carbon fiber or paper and the like having the main body crashed.SELECTED DRAWING: Figure 1
