single crystal furnace welded bellow for accelerator and vacuum
industry
Drachma Material main products are metal welded bellows, magnetic
fluid seals and ultra-high vacuum components. Supply to
accelerator, semiconductor, TFT-LCD, photovoltaic and other
industries, has been recognized by technology, product quality.
———Brief Introduction
Welding bellows is a new type of component emerging at home and
abroad in recent years. It can be used as a sensitive component,
sealing component, isolation medium, pipeline connection and
temperature compensator. It in addition to pressure resistance,
temperature resistance, corrosion resistance, good sealing and
other advantages, compared with the traditional shape of bellows
there are two outstanding advantages: large deformation, long life.
———Schematic diagram
Its composition is composed of two formed hollow diaphragm with
concentric circle for inner edge welding to form a diaphragm pair,
and then a plurality of diaphragm pairs stacked together for outer
edge welding to form a corrugated section, and then at both ends
and end plate metal welding combined into a bellows group, so that
it can be reciprocated with other moving parts according to the
external needs
