Application of low melting point alloy in automatic fire hydrant and high pressure fusible valve

Automatic fire hydrants and high-pressure fusible valves usually use eutectic low melting point alloys with a melting point of 68-72 degrees. When the surrounding temperature reaches the melting point, the fusible alloys will melt and flow out, and the control mechanism will start to function. Fire hydrants and fusible valves are used as automatic Safety devices such as drinking water trucks, automatic alarm devices and automatic fire doors, and safety valves of high-pressure containers are made of low-melting alloys. With the change of working conditions, low-melting alloys with different melting points can be selected.
