Embodiment Construction

[0020] The spherical filter screen is fixed with the locking bolt in the inner passage on the water inlet side of the nozzle. One end of the spring is set on the rubber ball, and the other end is embedded in the recess of the middle nozzle; the rubber ball is pushed by the spring to move toward the water inlet, and is in circumferential contact with the conical sealing seat of the body to maintain a sealed state. The spray core is assembled in the inlet of each nozzle, and the dust cover is set on the outer circle of each nozzle. Usually, the rubber ball is in line contact with the conical sealing seat of the body under the thrust of the spring, so that the nozzle is kept in a closed and sealed state. When spraying starts, because the water pressure does not reach the predetermined pressure value, the nozzle is always in a closed and sealed state; when the water inlet pressure reaches the predetermined pressure value, the water flow pushes the spring and the rubber ball to mov...

Abstract

The invention discloses a fine water mist spray head, which is sealed at normal times, is started for spraying when a water feeding pressure reaches a preset value, is used for decomposing water current into fine and dense water drops of smaller than 200 mum for spraying and is shut down and sealed automatically when the feeding water pressure of the spray head falls. The spray head consists of a plurality of size nozzles and a middle nozzle; and a spring pre-fastening rubber ball body is arranged inside the spray head for sealing, so that the spray head is kept in a shut-down state. An anti-dripping fine water mist spray head belongs to the field of fire control. Damages of lightning flash, electric shock and the like caused by flowing liner water current discharged at the start of spraying and at the end of spraying existing in the conventional spray head are eliminated. The anti-dripping fine water mist spray head is provided with a pre-tightening spring, a rubber ball body, a dust-proof cover and a convex ball filter screen. The rubber ball body is closed by pre-tightening, water is not discharged under low water pressures and at the start/end stage of spraying, water discharge is started only when a preset water pressure is reached, and water is rotationally atomized and sprayed out through an atomizing core and the nozzle. The spray head has wide application prospects in the fields of electric power, petrochemical engineering, metallurgy, transportation and the like, and has unique safety on the protection of high-voltage power distribution equipment, diesel engine generator rooms, power transformers and converters.

Description

technical field [0001] The invention relates to a fine water mist nozzle used in the fire protection industry, which is usually closed and sealed, and sprayed when the water inlet pressure reaches a predetermined value, and the water flow is decomposed into fine water droplets smaller than 200um and sprayed out. The nozzle is automatically closed when the water inlet pressure is lost. , Belongs to the field of fire extinguishing, fire control and fire prevention. Background technique [0002] The current national standard GB5135.5-2003 water mist nozzle. The rated working pressure is low, 0.35MPa; the outlet is normally open; the fog droplets are relatively thick, the flow rate is relatively large, and there is no dust cover and filter screen. [0003] At present, the outlet of the nozzle is always open, and dust and corrosive harmful gases are easy to invade the nozzle and pipe network, which will damage the life of the system. [0004] Without a dust cover, the dust and ...
