Product Description

Product Description

Features

1. There is a little resistance when water flowing through the
equipment.
2. The main structure is made of grey cast-iron(or spherical graphite
cast iron) by little inner stress so it is long service life and small
deforming.
3. Structural strength is up to different hydraulic pressure, so it is
wide and economic in application.
4. Sealed with bronze through precise processing. Small friction and
good seal function. Forward leakage is less than 0.72L/min, and
reversal leakage is less than 1.25L/min.
5. There are various structures applied to many situations' installation.

Start-closeForcc

Start force: Fe=F+W,+W
Close force: Fa=F W,W2
And W,-Theory weight of body (kg), can be seen in table;
W2- Weight of lead screw (kg);
W2=(H+1000-D/2)g;
H-Distance from the center of hole to flat-form;
g-Weight per meter of lead screw;
F-Fraction force in condition of different water depth
and surface (estimation), unit value: 350kgf/m2.m;
F=350.S h(kgf)
S-Body surface(m²),Rectangle gate:S=a b; a-Width of gate(m),
b-Height of gate(m)
Round gate: S= D2/4, D-Diameter of gate(m)
H- Distance from the center of gate hole to the highest liquid
level(water depth)(m);

Mounting Patterns

Out-attachment form
(code B, can be omitted)
Dimensions of preformed
holes are the same to
gate latus rectum applied
in all installations of one-
way and both-way gate.

Flange form (code F)
Applied in installations of
pipeline port . Flange norm:
JB/T81-94,PN0.25Mpa(no
holes on the mid-perpendic-
ular)

Mounting Patterns

Mounting Patterns

Flat bottom form (code
P)It is applied in situations
that prevent silt especially
massive accumulation. Wa-
ter velocity is so fast that
can develop flushing effect.

Integration form(self-
supporting form code Z)
Applied in situations that the
headstock gear is installed
over gate and gate is over
or approach the flat form in
shallow channel.

Embedded Parts

The spacing between the foundation grooves of a pre embedded part is generally 300mm, and it is welded in one step.

ShaftGuide Bracket

H+1000=(n+1)·C(initially make C 60d)
Generally not establish shaft guide bracket if H+1000<60d
or n0.5 and consider coupling sleeve if H+1000>6000
Note: Request C2D+500 when using coupling sleeve
Request C2D+300 when gate completely open
Data(C-1000)is for adjustment in layout

Ordering Instructions

1. Please note type, specification and structure forms after reading mentioned
content.
2. The data of gate forward bearing water head 10m. And the calculation of
backward bearing water head is 2.5m. Please special order if go beyond
the pressure.
3. The gate body and door frame material are generally made of gray
cast iron. The sealing surface is tin bronze. If ductile iron, stainless
steel or HDPE (high-density polyethylene)plastic is required,specifid
requirements should be specified.
4. Start and stop machine, lead screw,shaft guide bracket,electric cabinet
and all the embedded parts, which are suited with the gate, are extra
ordered in addition to sliding gate.
5. The difference between non-rising gate and sliding gate is the flange
dimension and start-close form. Please distinguish the name when order
and matched hand wheel and joined flange are needed especially order.
6. Please demand special data when canal cast iron gate (preformed groove
casting type) is needed
7. Related civil design data should be supplied when order is different from
our data.
8. Generally gate with two suspension centres is used in case that B > 2.5m
and B/A > 1.5. It should be ordered specially.
