Instructions for Plug/Holder Disassembly and Reassembly
The seal on the threaded plugs/holders found on TLV products is formed by a flat
metal gasket. There are various installation orientations for the gaskets, such as
horizontal, diagonal and downward, and the gasket may be pinched in the thread
recesses during assembly.
Instructions for Disassembly and Reassembly
①
Remove the plug/holder using a tool of the specified size (distance across flats).
②
The gasket should not be reused. Be sure to replace it with a new gasket.
③
Clean the gasket surfaces of the
plug/holder and the product body using a
rag and/or cleaning agents, then check to
make sure the surfaces are not scratched
or deformed.
④
Coat both the gasket surface of the
plug/holder and the threads of the
plug/holder with anti-seize, then press the
gasket onto the center of the gasket
surface of the plug/holder, making sure
the anti-seize affixes the gasket tightly to
the plug/holder. Check to make sure the
gasket is not caught in the recesses of
the threads.
⑤
Hold the plug/holder upside down to make
sure that the anti-seize makes the gasket
stick to the plug/holder even when the
plug/holder is held upside down.
⑥
Screw the plug/holder by hand into the
product body while making sure that the
gasket remains tightly affixed to the
center of the gasket surface of the
plug/holder. Make sure the entire gasket
is making contact with the gasket surface
of the product body. It is important at this point to make sure the gasket is not
pinched in the thread recesses of the plug/holder.
⑦
Tighten the plug/holder to the proper torque.
⑧
Next, begin the supply of steam and check to make sure there is no leakage from
the part just tightened. If there is leakage, immediately close the inlet valve and,
if there is a bypass valve, take the necessary steps to release any residual
pressure. After the surface of the product cools to room temperature, repeat the
procedure beginning from step
.
