Anti - ?corrosion ?Resilient Seated Gate Valve with groove end for water?
?
Grooved-End Gate Valve is widely used in firefighting, building, metallurgy and etc.
Easy to install and service and?Low cost
?
Resilient seat gate valves are employed in the transport of clean water.?
?
The valve gate or closure member is typically in the form of a wedge made of cast iron material
so as to be sufficiently rugged so as to be suitable for high pressure and high flow applications.?
?
In a resilient seat gate valve, the outer surface of the valve wedge is coated with an elastomeric
material so as to offer a bubble-tight seal even at elevated operating pressures.?
?
The valve wedge is operated by turning a threaded stem so as to advance or retract the valve
wedge within the waterway of the valve housing.?
?
Upon valve closure, the resilient material on the edge forms a bubble-tight seal with the internal
surface of the valve body. Dirt or other contamination in the valve operating system can lead to
incomplete sealing of the wedge or other malfunction.
?
Another object of the present invention is to provide a resilient seat gate valve having an
improved wedge operator system which readily overcomes the deleterious effects of contamination introduced either during construction or entrained within product carried to the valve.
?
These and other objects of the present invention which will become apparent from studying the
appended description and drawings are provided in a valve arrangement, that comprises a valve
housing that defines a water passageway and a valve seat within the valve passageway.?
?
A valve wedge disposed within the housing passageway moves along a direction of operation
between a closed position in contact with the valve seat to block flow of water through the valve
passageway and an open position allowing flow of water through the valve passageway.?
?
A pair of spaced apart tracks are disposed within the valve housing on either side of the wedge
and extend along the direction of operation. A pair of opposed wings carried on the valve wedge,
travel in each track. A valve stem coupled to the valve wedge moves the valve wedge in opposite reciprocating directions between valve open and valve closed positions.?
?
Rollers are carried on the wings for rolling engagement with the tracks and scraper blades are
carried on the wings adjacent the rollers to scrape contamination from the tracks.?
?
The tracks may be provided with or without a liner. If a wing is provided without rollers because of
a light loading application, for example, the track is preferably provided without a liner.?
?
A light loading condition may arise, for example, at the upper end of a horizontally oriented
valve arrangement. However, under heavy loading conditions as, for example, at the bottom
end of a horizontally operated valve arrangement, it is preferred that the wings be provided
with load bearing rollers.?
?
In this instance, it is also preferred that the track be provided with a liner of generally U-shaped
cross-section and made of a rugged material such as stainless steel.
