La description
This series of three eccentricity metal butterfly valve seals are
my German MAK company introduced a new generation of technology
development Butterfly Products. With the traditional soft-sealed,
metal sealed butterfly valve compared to the product structure, it
mainly has the following characteristics: 1, the Vice-sealed
products using three-dimensional eccentricity metal seal structure,
in the traditional double eccentric structure on basic
configuration unique angle eccentric design, full use of the cam
effect, so that sealed the Deputy achieve instant contact and
instantaneous detachment, eliminating the macroscopic friction and
card squeeze , wear small, hoist torque small, sealed high
precision, high temperature, we use long life. 2, multiple
compensation functions: each single-layer metal seals flexible
compensation function that can play a role in the elimination of
space. Ring mounted on the valve sealing bed can slip in a certain
range, plus the role of torque, the elastic sealing ring and metal
of the contact angle between the valve seat have a minor effect
Lease block, and automatically, make position compensation. The
seal structure to seal the back of the introduction of pressure
medium, with medium pressure increased, the ring outer diameter and
also with the increase, so that the more strict sealing, the
formation of stress compensation. 3, stacked composite conical
metal seal sealed by a few layers, sealing access to the site is a
conical surface, rather than a line, sealed after the failure of
the first layer, as long as a little shift that may have several
layers from sealing role, overcome Seal Line Office in a sealed
after wear, is no longer sealed and the leakage of disadvantage.
Labyrinth seal ring means compensation within the multi-layer
composition, in contact with the seal seat to form a maze in order
to play a labyrinth sealing effect. 4, sealing adjustable
structure: the valve at the long-term use, if the sealing
performance drop, adjustable ring around the valve seat, you can
restore the original sealing performance significantly improve
valve life.
