Claims (1)
その開口部３の周縁に形成された弁座４とその弁座４に
下方から当接される栓体５とから成る弁６を備え、上記
栓体５４熱分解機構１Ｂを介して常時上記弁座４に押圧
して上記弁６を閉鎖させ、温度の上昇によって上記熱分
解機構１８が作動した際に上記抑圧が解かれ上記栓体５
が管枠２内の圧力水に押されて落下し上記弁６が開放さ
れるスプリンタラヘッドにおいて、上記弁６と熱分解機
構１８との間に、−側方に吸気口９が開口された減圧室
７をはさんで上記開口部３より径の大きい放出口８が開
口されてエゼクタ１０が構成され、上記吸気口９に吹鳴
体１１が設けられると六もに、上記栓体５が下方へ延長
されて上記放出口８を貫通し、さらに上記栓体５の径が
上記熱分解機構１８の作動時にその栓体５が落下するの
に支障のない程度に上記放出口８の径と近似の値に選ば
れてなることを特徴とする流水警報装置の機能を備えた
スプリンタラヘッド。At the lower end opening 3 of the pipe line 2 connected to water pipes etc.
The valve 6 includes a valve seat 4 formed on the periphery of the opening 3 and a stopper 5 that abuts the valve seat 4 from below. The valve 6 is closed by pressing against the seat 4, and when the thermal decomposition mechanism 18 is activated due to a rise in temperature, the suppression is released and the stopper 5 is closed.
In the splinter head, in which the fuel is pushed down by the pressure water in the tube frame 2 and the valve 6 is opened, an intake port 9 is opened on the − side between the valve 6 and the thermal decomposition mechanism 18. An ejector 10 is constructed by opening a discharge port 8 having a larger diameter than the opening 3 across the decompression chamber 7, and when a blower 11 is provided at the intake port 9, the stopper 5 is opened. The diameter of the stopper 5 is the same as the diameter of the release port 8 to such an extent that it does not interfere with the stopper 5 falling when the thermal decomposition mechanism 18 is activated. A splinter head equipped with the function of a running water alarm device characterized by being selected to approximate values.
