Claims (1)
- 火災時に消火用配管に接続された消火用散水ノズルから消火液または水を放射して消火を行う固定式消火設備の散水ノズルに於いて、
前記消火用散水ノズルから前記消火液または水を脈動的に放射する脈動放射機構を有し、前記脈動機構は、水圧により弁体の開閉動作を行い脈動放射を行う水圧作動機構を備え、
前記水圧作動機構は、
外筒と、
該外筒内に上下動自在に収納される下端部に放水口を備えた内筒と、
前記外筒と前記内筒との間に形成され、前記内筒から導入された水圧により前記内筒を上昇させる圧力室と、
前記外筒と前記内筒との間に上下動自在に設けられ、前記内筒が所定の位置より上にあるときは前記内筒内から前記圧力室への水圧を遮断し前記内筒が所定の位置まで下降したとき前記内筒内の水圧を前記圧力室へ導入する可動開閉リング部材とからなり、
前記圧力室への水圧の導入と遮断の切り換え及び前記内筒にかかる下降方向へ移動させる水圧による前記内筒の上下動により放水口と消火液または水を散水するデフレクタとの間隔を変化することにより脈動放射を行うことを特徴とする消火用散水ノズル。
