Unsealing device for gas cylinder

Abstract

The invention provides an unsealing device for a gas cylinder which is suitable for a carbon dioxide fire extinguisher for home or office using cartridge type gas cylinders e.g., wherein miniaturization / lightening and improvement of appearance are realized by incorporating one or more gas cylinders, and the gas cylinders can speedily and safely be used and stable and sufficient fire extinguishing operation is obtained by unsealing them simply and simultaneously, and stable fire extinguishing operation is obtained by preventing condensation of dry ice and clogging of a channel after unsealing. An unsealing device for a gas cylinder comprising gas cylinder filled with gas and sealed at the opening by a seal plate, and a hollow cylinder body for accommodating the gas cylinder, and a cylinder holder capable of keeping the opening at the fixed position on the cylinder and a tip part for unsealing the seal plate, and a needle for guiding the gas to outside and a needle holder for keeping the needle. The cylinder holder and the needle holder are separated, and the needle holder can move to relatively close. Several cylinder holders and needle holders are arranged within the cylinder body. The cylinder body accommodating several gas cylinders in coaxial direction. The cylinder holders and needle holders are configured to move only once, and the seal plate can be opened in substantial one time.

Description

technical field [0001] The present invention relates to a carbon dioxide fire extinguisher suitable for use in homes, offices or vehicles such as cassette-type gas cylinders. Several gas cylinders are compactly accommodated in the barrel to achieve small size, light weight and improved appearance, and these gas cylinders can be It is easy and safe to open at once, and can quickly and safely use a large amount of gas. After the gas cylinder is opened, it can prevent dry ice condensation or blockage of the flow path, and can obtain a gas cylinder opening device in a stable gas ejection state. Background technique [0002] Carbon dioxide fire extinguishers are used as fire extinguishers for electrical equipment, oil fires, etc., and are widely favored for reasons such as no staining after use, and stable quality over a long period of time. A known carbon dioxide fire extinguisher has: a cylinder filled with high-pressure carbon dioxide; a spray head connected to the cylinder; ...

AI Technical Summary

Problems solved by technology

[0009] But above-mentioned opening device needs bigger force when opening of steel cylinder sealing plate, and its opening means adopts electrical ignition type detonator, and utilizes the gimmick of the gas enclosed in detonator to detonate in detonator by electric ignition mode, thereby equipment is huge and Delicate, high unit price, it is difficult to obtain simple operation, rapidity and safety, and because several steel cylinders are arranged side by side, the device tends to be large and inconvenient to operate, it is difficult to use in fire extinguishers or small household fire extinguishers
