Abstract

The invention relates to a liquid CO2 extinguisher filling device, wherein a PLC (Programmable Logic Controller) control system is adopted. The liquid CO2 extinguisher filling device is characterized in that a production line traverses a main body of the device, the main body of the device is arranged on a weighing sensor and a base is arranged under the weighing sensor; the production line comprises a machine frame, a positioning control device is arranged on the machine frame, a transmission roller chain is arranged in the middle of the machine frame and a tool plate used for placing a CO2 extinguisher gas bottle is arranged on the transmission roller chain; and the upper part of the main body of the device is of a frame structure, a bottle supporting cylinder is arranged at the midpoint on the weighing sensor at the lower part of the main body of the device, one side of the frame of the main body of the device is provided with an aeration component capable of moving along with a guide rail and the other side of the frame is provided with a clamping cylinder. Under high-pressure and low-temperature CO2 filling conditions, the liquid CO2 extinguisher filling device provided by the invention has the advantages of high filling precision, high efficiency, little waste, and safety and convenience for operation and is suitable for batch assembly line work.

Description

technical field [0001] The invention relates to a filling device, in particular to a filling device for a liquid CO2 fire extinguisher. Background technique [0002] Liquid CO2 fire extinguisher is a high-pressure pressure vessel with a working pressure of 15MPa-25MPa. Liquid CO2 filling is a special operation with certain risks. CO2 filling is characterized by high pressure and low temperature, high filling accuracy requirements, and mass production flow operations. According to the GB4351 standard, the tolerance of the filling volume of liquid CO2 fire extinguishers is 0~-5%. The structure diagram of the CO2 fire extinguisher filling equipment in the prior art is as follows: figure 1 When operating, put the gas cylinder on the electronic scale 25 to weigh the empty cylinder, then open the valve 22 of the booster pump 22, the liquid CO2 enters the CO2 fire extinguisher gas cylinder valve 24 interface through the connecting hose 23, and observe the electronic scale 25. Wh...
