Liquid carbon dioxide fire extinguisher inflatable equipment

Abstract

The invention discloses a filling device for a liquid carbon dioxide fire extinguisher, which relates to the technical field of fire extinguishers; it includes a station for charging the fire extinguisher, a gas storage tank, a booster pump connected to the gas outlet of the gas storage tank, and a booster pump for connecting and the air return pipe of the air inlet of the air storage tank, and the automatic valve on the return pipe; the station includes an inflatable head for connecting the fire extinguisher and inflating, an inflatable pipe connected with the inflatable head at one end, and a gas pipe connected with the inflatable pipe at one end. Exhaust pipe, exhaust valve on the exhaust pipe, inflation valve on the inflation pipe; the section of the return pipe between the booster pump and the automatic valve is named the first section, and the inflation pipe is far away from the inflation pipe. One end of the head communicates with the first section; the charging valve is located on the side of the exhaust pipe close to the booster pump. When not inflated, the gas in the inflatable tube flows to avoid excessive pressure in the inflatable tube and the pipeline is safe.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishers, in particular to an inflatable device for a liquid carbon dioxide fire extinguisher. Background technique [0002] When the carbon dioxide fire extinguisher is produced, it is necessary to inflate the fire extinguisher. When inflating, the inflatable head is screwed to the inflation port of the fire extinguisher, and then the inflation valve is opened. After the inflation is completed, the inflation valve is closed. In this inflation method, when not inflating, The gas in the inflatable tube does not flow, the inflatable tube is under high pressure, and the pipeline is not safe. Simultaneously, after the inflation is completed, there is still high-pressure gas between the inflation head and the inflation port, and the inflation head is not easy to disengage from the inflation port, and the ejection of the high-pressure gas after disengagement will cause a potential safety hazard.
