HEAD OF CIRCULAR SPRINKLER HAVING EARLY REACTIVITY

摘要

The present invention relates to a premature reaction-type circular sprinkler heads, fire is installed to be exposed to the ceiling of the building in the event of a fire will allow you to quickly flood the firefighters to quickly suppress early. ; For this, chulsugu (21) is formed with the body (20), the bottom surface of the body is installed to be kept confidential, and a plunger closing the chulsugu 30 threaded hole 31 is formed in the center of the bottom, or the set screw hole and screwed on the screw 50, the conical portion at the same time screwed to the body soon as a plurality of the injection port 13 is formed and the inner peripheral surface was the depth than the radius of the ball in the through-hole 15 formed at the bottom center of the shallow, the downward inclined surface (14a) (14b) is provided with a receiving space (14) a frame having a 10, a plurality of balls (70) and being located in the receiving space, the inner flange is loaded to apply a load to the ball position in the receiving space in accordance with the rotation of the screw is set to direct the room of the plunger plate 40, has a cut-out portion (61) to partially accommodate the ball was loaded to the outer plate 60 is detached from the frame with the ball during a fire, is located immediately below the outer chamber of the loading plate fire and the heat collector 80 is made of a plurality of quick response to the event of opening, of the heat collector is installed inside of the heat collector that is located in the lowermost room fuse metal 90 and, is screwed to the inner loading plate inner loading plate , the outer loading plate, and the locking screw (100) for integrating the heat collector, the outer load plate and the heat collector is disposed between the heat collector with an insulating washer 110, to prevent the conduction of heat to the outer during the loading plate sensitized will be constructed.
