Source of extinguishant

The filling is based on the unique property of carbon dioxide. When the CO₂ extinguishant source is heated to some extent in the thermal thermostat, it is fed into the cold thermostat via pipes because of heating and increased pressure. When it is cooled, the pressure is reduced. The CO₂ is filled into the container through the console by using the high pressure as the motive force to drive lower pressure.

IV. Main Structure and Functions

GTM-B Type filler for CO₂ fire extinguisher is chiefly composed of filling console, thermal thermostat, cold thermostat and electronic scale.

1. Filling console is used for controlling the quantity of filling the cylinder with CO₂ extinguishant. On it are mounted XMTA temperature controller, T3806 type electronic scale indictor, power source voltage indicator, GT solenoid valve and control panel for electric appliances.

Heater terminal (No.1 in Figure 1)—for heating the gas source cylinder

Gas source cylinder (No.2 in Figure 1)—changing the fire extinguisher

Sensor (No.3 in Figure 1)—for sensing the heating temperature

II character-type fixture (No.4 in Figure 1)—interface to the gas source

Gas outlet (No.5 in Figure 1)—the gas outlet of gas in the cold thermostat, connected to the console

Exit valve (No.6 in Figure 1)—opening or closing the gas outlet

Gas inlet A (No.7 in Figure 1) and Gas inlet B (No.8 in Figure 1) for connecting to gas source

Inlet valve A (No.9 in Figure 1) and Inlet valve B (No.10 in Figure 1)—opening or closing the gas inlet

Gas source pressure meter B (No.11 in Figure 1) and Gas source pressure meter A (No.15 in Figure 1)—for display of gas source pressure

Mixer (No.12 in Figure 1)—making the temperature of cold thermostat uniform

Operating indication lamp (No.13 in Figure 1)—showing the refrigerator is in operation

Power source indication lamp (No.14 in Figure 1)—showing the refrigerator is energized

SJP-1 Temperature Controller (No.16 in Figure 1)—intelligent regulation of temperature

Charge pressure indicator (No.17 in Figure 1)—showing the charge pressure

Power source switch (No.18 in Figure 1)—controlling the start and suspension of refrigerating system

T3806 indicator (No.19 in Figure 1)—showing the quantity filled in the cylinder

Control panel for electric appliances (No.20 in Figure 1)—for operating and controlling the completion of all jobs.

Charge pipe (No.21 in Figure 1)—for connecting the console of filling and the cylinder valve (No.22 in Figure 1)—controlling the outlet and inlet of cylinder gas.

II character-type fixture (No.23 in Figure 1)—for clipping the filled cylinder

Cylinder (No.24 in Figure 1)—the filed cylinder

Stand of electronic scale (No.25 in Figure 1)—for sensing the weight of cylinder

Compressor (No.26 in Figure 1)—completing the refrigeration operation

2. Thermal thermostat is composed of a water bath, a support and a heater for thermal uniform temperature treatment of CO₂extinguishant to meet the requirement of filling technology.

3. Cold thermostat is composed of box body, stainless steel liner, evaporator, refrigerating compressor, temperature controller and pressure indicator. It can reduce the temperature of CO₂ fire extinguishant by mechanical refrigeration, which will meet the requirement of filling technology.
