[0004] Some cylinders are installed horizontally. In the horizontal installation, metal rigid tubes are generally used as siphon tubes, and the ends of the siphon tubes are bent toward the bottom of the cylinder through cold bending to ensure that the liquid fire extinguishing agent inside the cylinder can be fully utilized.

[0005] On the one hand, in the above two different installation methods, two different siphon tubes need to be used, and the siphon tube cannot be used in both installation methods.

[0006] On the other hand, in horizontal installation, the installer cannot identify the true orientation of the end of the siphon tube, and may install the end of the siphon tube upward, affecting the normal firefighting operation of the overall fire extinguishing device. Utility Model Content

[0014] Furthermore, the device also includes a solenoid valve, which is installed on the bottle head valve and is located in the flow path of the liquid fire extinguishing agent, and can intermittently block the liquid fire extinguishing agent.

[0022] In the utility model, the siphon tube 1 is made of a metal hose and can be bent. A counterweight component 4 is also provided on the side of the geometric center of the siphon tube 1 away from the bottle head valve 2. Under the action of the gravity of the counterweight component 4, regardless of whether the cylinder 3 is installed vertically or horizontally, the counterweight component 4 can guide the end of the siphon tube 1 away from the bottle head valve 2 downward along the direction of gravity.
