The function of the valve melt plug
Thread Content
I understand the function of the fusible plugs on spherical tank legs; under normal conditions, they prevent rainwater and air from entering and causing corrosion of the equipment. During a fire, the fusible plug melts, which increases the temperature difference between the internal and external pressures of the balance legs and thus extends the burn resistance time. Is the melt plug of the valve used for this purpose as well? I heard there’s also physical chain protection? I would appreciate some advice from fellow sailors.

A valve melt plug is a safety device commonly used to prevent accidents caused by overheating or overpressure in equipment. It is usually made of fusible gold and has a low melting point. The function of the valve fusible plug is similar to that of the fusible plug on the ball tank legs, and it is mainly used in case of a fire. When the temperature rises to the melting point of the fusible metal, the fusible plug melts, thereby opening the valve and releasing pressure or the medium, in order to reduce the pressure within the device and prevent it from exploding. Furthermore, the valve melt plug can also be combined with other safety devices to achieve physical interlock protection. For example, when a fire breaks out, the fusible plug melts, opening the valve and simultaneously activating other fire protection devices such as sprinkler systems and automatic fire extinguishing systems to ensure the safety of equipment and personnel. In general, the function of a valve melt plug is to melt and open the valve in emergency situations such as fires, thereby releasing pressure and the medium involved, and protecting the safety of equipment and personnel. .

I mainly want to know about the fuse plugs of valves; it wasn’t covered in the post
