Embodiment Construction

[0013] Three casing design is adopted, the principle of hydraulic jacking and spring reset is adopted, and the water distribution structure is impacted and splashed by multiple streams of water. The cyclone is plugged in the hole of the inner casing and is limited by the circlip. In the groove, the outer circle of the inner casing and the inner hole of the middle casing are designed as a clearance fit, and are guided at two places up and down; after the water distribution plate is matched with the inner casing, it is fastened by screws, and the spring is installed between the middle casing and the inner casing. The middle casing is screwed into the hole of the outer casing, sealed with a gasket and fastened by a locking buckle; the outer casing is embedded in the deck step hole, the upper surface of the outer casing is flush with the deck, and the lower part of the outer casing is straight to the water supply main pipe. The threaded connection is sealed and fastened by double l...

Abstract

The invention provides a shower nozzle for a deck. The shower nozzle adopts the design of three sleeves, the principles of hydraulic jacking and spring return, and a water distribution structure that multiple water flows splash back through impact, belongs to the field of fire control, and solves the problems that a conventional shower nozzle interfere with the operation of an aircraft and a vehicle, the foam expansion is low, the foam stability is poor, and the coverage is small. A swirler is plugged in an inner sleeve hole. A water distribution plate and an inner sleeve are fastened by a screw. The springs are arranged between a middle sleeve and the inner sleeve. The middle sleeve is screwed in an outer sleeve hole. At ordinary times, the water distribution plate are pushed by the springs, so that the water distribution plate maintains a level with the deck. In spraying, a fire fighting medium enters the swirler, and is sprayed out from a double-ring water outlet in the top of the inner sleeve; besides, the water distribution plate and the inner sleeve compress the springs to move up and come out from the deck under the hydraulic action, and after splashing back through impact of the water distribution plate, the fire fighting medium covers protection areas in a lotus leaf shape; and the shower nozzle comprises an outer sleeve, the inner sleeve, seal gaskets, a snap spring, the swirler, locking buttons, locking nuts, the springs, the middle sleeve, a seal ring and the water distribution plate. The shower nozzle is suitable for protecting flight decks of naval ships, hangars, dangerous cargo wharfs and trestles.

Description

technical field [0001] The invention relates to a deck sprinkler used in the fire protection industry, which covers the fire extinguishing medium to the protected area in the shape of a lotus leaf, adopts the design of three casings, the principle of hydraulic jacking and spring reset, and multiple streams of water flow impact the backsplash cloth. The water structure belongs to the field of fire extinguishing and fire control. Background technique [0002] The water mist nozzles in the current national standard GB5135.5-2003 have spray angles of 90° and 120°, and the spraying of fire extinguishing medium is relatively high, which is greatly affected by wind force and covers a small area. [0003] There is no cyclone in the flow channel of the current deck nozzle, and the foam mixture is not pre-stirred and mixed, the foaming ratio is low, and the fluidity and stability of the foam are poor; there is no jacking and reset mechanism; the nozzle is protruding, which is not suit...
