Embodiment 1

[0018] Such as figure 1 As shown, the fire-fighting water curtain nozzle provided by the present invention includes a nozzle base 1 connected with a fire-fighting water pipe using an internal thread or an external thread, a fire-fighting water channel 3 arranged in the nozzle base 1, and a hemisphere arranged at the bottom of the nozzle base 1 Body 2, set in the hemispherical body 2, communicate with the fire water channel 3 and be an ellipsoidal cavity 4, be arranged in the cavity 4, be used for the hollow sphere 5 of fire water pressure equalization in this cavity 4, and several The root is set on the hemisphere, one end is connected to the inner wall of the cavity 4, and the other end communicates with the outside world, forming a fan-shaped nozzle 6 with the center of the cavity as the center. Wherein, the diameter of the hollow sphere 5 is larger than the diameter of the fire water channel 3 . In addition, the fan-shaped fan angle formed by several nozzles 6 is greater t...

Embodiment 2

[0020] Such as figure 2 As shown, the tunnel fire separation system provided by this implementation includes several fire-fighting water curtain nozzles 11 that are installed on the top of the tunnel and are evenly distributed in rows. Pipe 12, partition branch pipe 13 connected with water curtain fixed pipe 12, fire deluge valve 14 connected with partition branch pipe 13, fire controller 15 and fire main pipe 16 respectively connected with fire deluge valve 14, connected with fire controller And several fire alarms 20 installed on the top of the tunnel, the main fire water valve 17 connected with the fire main pipe 16, the booster pump 18 connected with the fire water main valve 17, and the high-level fire water pool 19 connected with the booster pump 18 . Wherein, several fire-fighting deluge valves 14 are provided, and the number of partition branch pipes 13 is the same as the number of fire-fighting deluge valves 14, and the partition branch pipes 13 are connected to the...

Abstract

The invention discloses a fire-protection water curtain spray nozzle. The problem of no fire separation facility in the longitudinal direction of a tunnel existing in the prior art is solved. The fire-protection water curtain spray nozzle comprises a spray nozzle base, a fire protection channel, a hemispheroid, a cavity, a hollow sphere, and a plurality of spray pipes; the spray nozzle base is connected with a fire protection pipe by an internal thread or an external thread, the fire protection channel is disposed in the spray nozzle base, the hemispheroid is disposed at the bottom of the spray nozzle base, the cavity in the shape of an ellipsoid is installed in the hemispheroid and communicates with the fire protection channel, the hollow sphere is disposed in the cavity and used for thepressure equalization of fire water in the cavity, the spray pipes are installed on the hemispheroid, one ends of the spray pipes are connected to the inner wall of the cavity, the other ends of the spray pipes communicate with the outside and the fan-shaped spray pipes centered on the center of sphere of the cavity are formed. The invention further provides a tunnel fire separation system. The fire-protection water curtain spray nozzle has the advantages of simple structure, uniform spraying thickness of water curtain, wide coverage area, and wide application range, fire water is saved, and high practical value and popularization value are obtained in the field of fire protection technology.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire water curtain sprinkler and a tunnel fire separation system composed of the same. Background technique [0002] With the continuous improvement of social development and the continuous improvement of traffic conditions and engineering construction technology, traffic tunnels have developed rapidly and play an important role in transportation. Since the tunnel is a relatively closed space, and the terrain of the traffic tunnel is complex, the driving vehicle is affected by factors such as light and weather, and the probability of accidents in the tunnel is relatively high. Therefore, while controlling the speed of the driving vehicle, the traffic The tunnel itself also needs to meet fire protection, ventilation, lighting and other requirements. [0003] Tunnel fires include tunnel ancillary room fires, tunnel equipment fires, and car fires in the tunnel; when vehic...
