Deluge nozzle / sprinkler head

Water-spray discharge head on a short flanged drop (port A at the weld-neck flange, forged reducing coupling to a ½" NPT head, tie-wired tag). kind mv is an open medium-velocity nozzle with a hollow orifice and a slotted external deflector on two frame arms; hv a high-velocity conical nozzle with an open orifice and swirl vane; sprinkler a pendent glass-bulb sprinkler whose bulb colour follows temperature; water-mist a stainless head with nine micro-nozzles. spray draws the discharge cone at angle. Use kind, not type (reserved by Object3D).

Installation

$npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add deluge-nozzle

Copies safety/deluge-nozzle.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.

Usage

import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { DelugeNozzle } from './components/deck-twin/safety/deluge-nozzle'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <DelugeNozzle />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )
}

P&ID

P&ID symbol for deluge-nozzle

On deluge layouts and isometrics: a short drop from the deluge pipe ending in a nozzle (small open cone or triangle) with its spray pattern; closed sprinkler heads are a circle with a dot. The nozzle type and K-factor are tabulated.

tag NZFire-protection layout / isometric convention (NFPA 15 / NFPA 13)

Open nozzle (no bulb) = deluge; a sprinkler head (bulb) is drawn as a filled circle or circle with a dot. On P&IDs a deluge network is one line after the deluge valve with "nozzles" noted.

Machine-readable entry with props, ranges, defaults and ports:

$npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info deluge-nozzle

Or fetch /r/deluge-nozzle.json, or copy a ready-made instruction:

Add the Deck Twin "Deluge nozzle / sprinkler head" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add deluge-nozzle` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info deluge-nozzle` for its props, ranges and ports. Render <DelugeNozzle /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
