Three Eccentric butterfly valveThree Eccentric butterfly valve
The high performance three eccentric butterfly valve
produced by our company is the latest generation high
performance three eccentric metal sealing type after
enhancement with innovative theory, possessing the
characteristics as follows:
Anti-Blow Out Design
The minimum loading side of stem strength design is
located outside of valve pressure edge, which conforms to
API609 anti-blow out structure, prevent accident
presumed when the stem is broken and with internal
media pressure, piston effect occurs and cause to blast
out.
Multi-Functional Axial Sealing Structure
a.The valve adopts soft graphite sealing packing and also
disc shape spring pre-fastening device, when the sealing
function decreases due to long term usage of the packing,
it’ll adjust axial sealing pressure ratio automatically,
assures axial sealing zero leakage(Fig.1)
b.Under fugitive medium condition, can use low leakage
carbon fiber bowl mode combined packing structure, meet
the regulation and requirement of ISO 15848 and API 622
standard(Fig.2)
c.Add isolation ring between the dual combination
packing, leakage device can be added at the isolation ring
according to request, which is applicable in vacuum
system(Fig.3) and steam system(Fig.4) etc. high
requirement conditions to achieve reliable sealing.
Bearing System
a.When working temperature not above 270℃, adopt
stainless steel stem after thermal treatment and non-oil self
lubricated bearing, the dry friction factor between stem and
bearing is only 0.05~0.1, the on/off torque of valve is
reduced greatly; When working temperature is above 270℃,
adopt stainless steel stem after thermal treatment and
austenite cast iron or alloy steel azotizing bearing, to
prevent non-smooth and scratch etc. problems due to long
term usage.
b. Adopt adjustable structure, it can adjust the central
position of disc sealing ring through bolts, to achieve one
best sealing effect with seat.
.
Optional Three-Dimensional Eccentric Design
The First Eccentric A is eccentric between valve axial center
and valve body center. When disc opens, rotation of disc
causes similar Cam effect and breaks away from seat
quickly, when disc closes, its moves from similar Cam
movement to linear movement, to achieve the effect sealing
pressure ratio becomes bigger while closing.
The Second Eccentric B is, stem is offline from sealing face
center, to assure sealing face will not be interrupted by
stem.
The Third Eccentric C is cone angle eccentric between
rotation center axial and valve central line.
Firesafe Function
Firesafe function is adherent
character of three eccentric
metal hard sealing, conforms to
ISO 10497 and API 607 standard
requirement.
