Sprinkler with an integrated valve, and fire-extinguishing system using same

摘要

The present invention relates to a sprinkler with an integrated valve, and to a fire-extinguishing system using same. Conventional sprinklers are too sensitive to the outbreak of a fire, and operate even if no fire has broken out, which would lead to a large amount of damage. For this reason, conventional sprinklers are often prevented from being operated in advance. In addition, sprinklers do not operate even upon the outbreak of a fire when the sensitivities thereof are lowered, rendering the sprinklers useless. The present invention aims to solve the abovementioned problems, and is configured such that a manager in a building checks whether or not a fire has broken out and if so sends an extinguishing signal, and wherein in the event a sensor for operating a sprinkler senses the outbreak of a fire, only the relevant sprinkler operates by means of a valve mounted thereon, thereby operating sprinklers only when a fire has actually broken out, and enabling a central control office, a fire station, or the like to verify the outbreak of a fire in each household at all times. Further the present invention can be applied to public transportation facilities such that water-spraying is carried out after an engine room or a control board in charge of the safety of the passenger cars and outside of the latter verifies the outbreak of a fire, thus still taking advantage of a high-sensitivity of sensor. As the present invention sprinklers water only in the event of an actual fire outbreak, erroneous operation can be prevented, and water can be sprinkled only in the required area, thereby extinguishing the fire in the early state of a fire outbreak.

主权项

1. A valve united sprinkler comprising:
an open sprinkler head that is connected to a fire extinguishing solvent storage to sprinkle the solvent; a sprinkler valve that is located between the solvent storage and the sprinkler head to open up the sprinkler head; a sprinkler sensor that is located near the sprinkler head to detect a fire; and a sprinkler controller that controls only the sprinkler valve and makes the sprinkler valve operate, wherein the sprinkler controller comprises:
a plurality of external detector signal input pins that are communicatively connected to a plurality of external detectors that are not part of the sprinkler but are located near the sprinkler to detect a fire, in order to receive fire detection signals from the external detectors;a fire alarm signal output pin through which to output a fire alarm signal generated from the fire detection signals generated from the fire detection signals to a control panel;a fire extinguishing signal input pin through which to receive a fire extinguishing signal generated by the control panel in response to depression of a fire extinguishing button of the control panel after a fire has been recognized by an operator that presses the fire extinguishing button; anda sprinkler sensor signal input pin through which to receive a sprinkler sensor signal from the sprinkler sensor that is attached to the sprinkler and detects a fire, wherein the sprinkler controller activates the sprinkler valve in response to determining that (i) at least one of the fire detection signals generated by the external detectors indicates a fire is detected and (ii) the fire extinguishing signal indicates a fire has been recognized or the sprinkler sensor signal indicates a fire is detected, wherein the sprinkler controller generates the fire alarm signal indicating that a fire is detected in response to determining that (i) at least one of the fire detection signals generated by the external detectors indicates a fire is detected or (ii) the sprinkler sensor signal indicates a fire is detected.
