Chevron Packing will be
highly suitable for all your applications related from heavy duty to
medium duty. In robust conditions, it can help you bear low as well
as high pressure. Chevron packing seals are combination of header
ring, v ring and gland ring. In chevron packing, the center ring can
retain high and low pressure because of its flexibility. This center
ring may be known to you as main ring.
Materials that
makes a chevron packing complete
Headers are made of
phenolic resin, acetal resin, nylon, fabric rubber and reinforced
rubber due to there hardness. Radial slots are provided on the top of
the surface which helps in paying the pressure directly onto the lips
of the adjacent rings. V seals are made of high grade rubber which is
laminated synthetic fabric. It facilitates you an automatic sealing
action on the lip. Rubberized fabrics are used in V rings that are
used in Chevron packing. Using V seals in your chevron packing does
not require any pre-axial load. Gland ring is also an essential part
of chevron packing. Seal material are prevented from extrusion during
the clearance gap during high pressure because of the laminated
fabric synthetic rubber used in in manufacturing these rings. These
ring used in your chevron pack have some properties like they are
designed to tolerate temperature ranging from -30 to +130 ℃
specifically in oil. Use of these type of materials helps in adopting
variety of extreme conditions.
Where can be
chevron packing be used?
Generally these can be
used in large earth moving equipments, hydraulic cranes, plunger
pumps and in many other the applications. These packing have been
found appropriate in robust conditions like in replacements of parts
in old plants. Chevron packing or 'V' packing combines same type of
rubber, the rings in-between provide very impressive sealing. The
system is so factory-made that it can grip prevailing pressure
occurrences like shock loading, axial movements, oscillations and
still loading etc.
