Wall Type Sluice Gates
General
Wall type sluice gates are designed for easy operation, low
maintenance and long life with the minimum of leakage. Corrosion resistant
materials are used throughout and they are particularly suitable for
installation against concrete walls at water and sewage treatment works.
Slide Gate
The slide gate is of a fabricated construction utilising press braking
and bolted ribs to maintain flatness. Welding is kept to a minimum to avoid
distortion. The gate is carefully designed to achieve a minimum deflection
under design load.
Frame
The frame incorporates guides to accommodate the sliding gate and the frame is
suitable for easy installation onto the concrete wall over the channel
outlet/inlet. Jacking bolts are used to level the frame prior to grouting.
After grouting, the inside of the frame will normally be flush with the
concrete channel walls.
Head Stock
The headstock is constructed from a tubular section and is designed to bolt to
the operating platform. The top of the headstock is flanged and is designed to
accommodate to spindle actuator of either the manual, or automatic type.
Sealing
The side seals are of the resilient type manufactured from extruded synthetic
rubber of a 'music note' cross section. The seals are positioned such that
sealing will improve as the water pressure increases in an 'on seating'
situation. In an 'off seating' situation, the seal relies on the compression of
the bulb of the seal.
When applicable the top seal is also of the 'music note' type and only locates
into position when the gate is closed.
The bottom seal is also of the resilient type manufactured from extruded
synthetic rubber in a flat section. The seal will seal against the bottom cross
member which is normally flush with the channel invert. Good sealing is
achieved with a moderate seating load. There are therefore no grooves to fill
with silt or other solids.
Channel Type Sluice Gates

General
Channel type sluice gates are designed for easy operation, low maintenance and
long life with the minimum of
leakage. Corrosion resistant materials are used throughout and they are
particularly suitable for installation in concrete channels at water and sewage
treatment works.
Slide Gate
The slide gate is of a fabricated construction utilising press braking and
bolted ribs to maintain flatness. Welding is kept to a minimum to
avoid distortion.
The gate is carefully designed to achieve a minimum deflection under design
load.
Lower Frame
The lower frame incorporates guides to accommodate the sliding gate and the
frame is suitable for easy installation into rebates cast into the sides and
invert of the concrete channel. After grouting, the inside of the frame will be
flush with the concrete channel walls.
Head Frame
The head frame is channel sections and is bolted accurately to the lower frame.
Guides give trouble free sliding of the gate. The horizontal cross member of
the head frame accommodates the spindle actuator manual or automatic.
Sealing
The side seals are of resilient synthetic rubber. They are positioned such that
sealing will improve as the water pressure increases and are easily replaceable
without removing of dismantling the gate. The bottom seal is resilient
synthetic rubber in a flat section. Good sealing is achieved with a moderate
seating load. There are therefore no grooves to fill with silt or other solids.
