Abstract

The invention relates to an airtightness testing apparatus of a gas storage steel cylinder container valve starter. The apparatus is characterized by comprising an airtightness testing apparatus body and a valve inside, wherein the center of the airtightness testing apparatus body is provided with a threaded circular hole, the circular hole is internally in threaded connection with the valve inside, the airtightness testing apparatus body is internally provided with an annular recessed bench in sealing connection with a starter interface, and the recessed bench communicates with the circular hole. The apparatus provided by the invention has the following advantages: compared to the prior art, a special test tool is provided for airtightness testing of such a key part, i.e., the starter; and a conventional airtightness detection method of the starter is improved, and the detection process is simplified.

Description

technical field [0001] The invention belongs to a detection device, in particular to an air tightness test device used for a valve actuator of a gas storage cylinder container of an inert gas fire extinguishing system. Background technique [0002] The gas fire extinguishing system is mainly used in environments where water fire extinguishing systems and other fire extinguishing systems are not suitable, such as computer rooms, important library archives, mobile communication base stations (rooms), UPS rooms, battery rooms, general diesel generator rooms, etc. . The gas fire extinguishing system includes automatic mixed gas. Its characteristics: the mixed gas fire extinguishing agent is a gas mixed with nitrogen, argon and carbon dioxide in a certain proportion. Greenhouse effect, and the mixed gas is non-toxic, colorless, odorless, non-corrosive, non-conductive, does not support combustion, and does not react with most substances. It is an ideal environment-friendly fire ...
