Abstract

[과제][assignment]

본체(21)내에 형성된 밸브좌구에 대하여 접촉분리동작하고, 또한 밸브폐쇄상태에서는 상기 밸브좌구의 상류측과 하류측을 연통시키는 리크구멍(240)이 뚫어 설치된 밸브체(24)와 본체(24) 내의 통수온도를 검지하여 이것이 이상고온으로 되었을 때에, 상기 밸브체(24)를 밸브폐쇄동작시키는 밸브구동 수단을 구비하는 감열식 긴급차단밸브에 있어서, 밸브작동상태에 있어서 본체(21)의 토출구(20)로부터 토출되는 온수의 온도저하를 도모할 수 있는 감열식 긴급차단 밸브를 제공하는 것.(24) provided with a leak hole (240) for communicating the upstream side and the downstream side of the valve seat with the valve body (24) And a valve driving means for closing the valve body (24) when the temperature of the water in the main body (21) becomes abnormally high, characterized in that the valve body 20) capable of reducing the temperature of the hot water discharged from the hot-water type emergency shut-off valve.

[해결수단][Solution]

밸브체(24)에 뚫어 설치된 리크구멍(240)의 하류끝개구의 개방방향을 밸브좌구의 개방방향과 교차하도록 설정하는 동시에 밸브체(24)가 밸브폐쇄한 상태에서는 상기 리크구멍(240)의 하류단개구부에 간격을 두고 대향하게 되는 확산벽을 설치하였다.The opening direction of the downstream end opening of the leak hole 240 formed in the valve body 24 is set so as to intersect with the opening direction of the valve seat 24 while the valve body 24 is closed, And a diffusion wall facing the downstream end opening with an interval therebetween.
