A fire extinguishing apparatus having a fire prediction function. The fire extinguishing apparatus includes: a fire extinguishing tube container having a fire extinguishing material therein, and automatically emitting the fire extinguishing material when being exposed to surrounding fire or heat; a fire pre-sensor coupled to one side of the fire extinguishing tube container and sensing surrounding presymptoms of a fire by measuring internal pressure of the fire extinguishing tube container; and a fire monitor connected to the fire pre-sensor and generating monitoring information while collecting internal state information and external environmental information of the fire extinguishing tube container. Therefore, the fire extinguishing apparatus can measure the internal pressure of the tube container for fire extinguishing, so as to predict and detect the occurrence of a nearby fire, and provide a notification to the outside through a network, so as to perform fire-related predictive maintenance and initial response.

A dry sprinkler includes a flexible tube section that maintains a pressurized fluid, such as a liquid antifreeze solution, between a first end and a second end. A first seal prevents fluid from a supply line from entering the flexible tube section. The first seal is maintained in a sealed position by a pressure of the pressurized fluid. A sprinkler head is coupled to the second end of the flexible tube section, and includes a frame, an output orifice, a deflector, a second seal that seals the output orifice, and a thermally responsive element configured to maintain the second seal in a sealed position when the thermally responsive element is in a non-responsive state. A differential pressure controller maintains a ratio between the pressure of the pressurized fluid in the flexible tube section and a pressure of a supply fluid in the supply line to at least a certain ratio.
