Features of fire extinguisher valve
Fire extinguisher valve is an important accessory for industrial and building pipeline control, this handout focuses on the practical application of the fire valve, detailed principles and structure of the cross-sectional view with reference to the relevant information, fire valve by the valve body, opening and closing mechanism, valve cover three major components.
When a fire extinguisher valve is exposed to fire (before and after a fire), we want to avoid two types of leaks: seat leaks and stem leaks. There are two other ways to achieve a fire-resistant design, one using fire resistant components and the other using non-fire-resistant components, but supported by a special design to prevent leaks when the components melt.
The first method of achieving fire-resistant design through the use of fire-resistant components usually refers to inherently fire extinguisher valves. Typically, this type of valve is a metal-seated valve that uses a graphite seat insert (in a ball or butterfly valve) and graphite stem packing. By using graphite as the seat insert and stem packing, the graphite will remain in place even after a fire.
The second method of achieving a fire-resistant design by using non-fire-resistant components is often referred to as fire tested valve. This valve uses a thermoplastic seat material and a thermoplastic stem packing, such as PTFE. in the seat design, even though the seat is thermoplastic, the design allows the thermoplastic to be machined into the body of the secondary seal to provide a seal when it melts due to high temperature exposure. In stem packing designs, the thermoplastic seal is typically supported by a graphite seal as a secondary packing.
