Fire control valve with pivotal latch |
摘要 |
<p>A valve installed in the flow line of a flammable or other hazardous flowable material which normally open but will be automatically closed to interrupt the flow of flammable or hazardous material to a discharge point in the event of a hazardous condition occurring. The valve is held in an open position by a fusible link which retains a pivotal latch in engagement with a spring biased valve to retain the valve in open position. The fusible link will melt when subjected to predetermined conditions such as a high temperature condition which occurs in the event of a fire thereby releasing the latch and valve for movement to a closed position for stopping flow of flammable material in order to control the fire or other hazardous condition.</p> |
