INTRODUCTION TO THE INVENTION
This Invention relates to the Diverter-valve /
deflector valve assembly for use in material conveying
purposes
PRIOR ART
Valves similar to this Diverter-valve are already
known for changing the direction of flow of material such as
air-born dry powdered material. These valves are used for
conveying variety of such air-bom materials with large range of
operating temperature and pressure.
DRAWBACK OF PRIOR ART
ln the valve of the known art, there is a
diversion surface inside the valve for diverting the flow path of
conveyed material which enters at the inlet port. This diversion-
surface is generally a uniformly curved surface. The conveyed
material impinging upon this curved surface is simply diverted
to a right-angle direction and the material normally grazes over
the curved surface. As a result, the speed of the impinging
material is not reduced to the desired extent. Hence it causes
downstream operational problems.
OBJECTS OF THE INVENTION
It is an objective of this invention to propose
an improved Diverter-valve which will significantly reduce the
speed of the conveyed material impinging upon a specially
designed diversion surface, thereby improving the downstream
It is another oject of this invention to propose
such a valve which can be fabricated close tolerance
It is a further object to propose such a valve
which will ensure smooth movement of the Movable-part
operating inside the Static-part of the diverter valve
It is still further object of this invention to
provide suitable sealing means so as to ensure prevention of
leakage of conveying material to the environment, that passes
through the valve.
These and other objectives will be more
significant from the following descriptions.

DETAILED DESCRIPTIONS OF DRAWING AND
HOW THE INVENTION WORKS.
Referring to the drawings it will be seen that
the Diverter-valve of this invention has a static-part 1 and a
Movable-part 2 which are shown in separate views for the sake
of convenience in Figures 1a & 1b. However, in Rgures-2&3
these are assembled and are placed in appropriate locations.
The Static-part is a structure of circular cross-
section and in the lower region of which it has Inlet-port 3 and
two outlet-ports 4 and 5. The Inlet-port and outlet-ports are
conveniently provided at the lower region of the Static-part.
While outlet-port 4 is in axial alignment with the inlet, the outlet
port-5is at 90 thereof.
The upper region of the Static-part is formed as a vertical
tubular member 1A to provide room for movements of the
movable-part 2 in an axial direction, inside the same.
The upper region of the Static-part is open. This opening is
covered by a cover-6 which has one central opening-6a for
mounting an Actuator-7 for operation of the diverter-valve. The
cover has another opening-6b on which a casing-tube-8 is
mounted. Inside the casing-tube an aligning-rod-9 moves
axially. The aligning-i J is mounted on the top plate-2a of the
movable part-2 at a convenient location such that the movable-
part while operating inside the static-part is prevented from
rotation.
Further the aligning-rod - 9 has an indicator-9a which acts as a
position-indicator for the valve. For this the aligning-rod casing-
lube-8 has two lndicators-8a and 8b. Alndicator-8b indicates
one positior when the diverted-valve conveys material from
inlet-port-3 to outlet-port-4 via a throu . pass-diverter-10 in the
movable part. lndicator-8a indicates another position when the
valve conveys material from lnlet-port-3 to outlet-port-5 at a
hight-angle direction via the Right Angled diverter-11 also in the
movable part at a location below the diverter-10, in the same
vertical axis.
As stated above, the static-part hcs a through-
pass-diverter 10 and right-angle-diverter 11. The through-pass-
diverter and the right-angle-diverter along with other components
explained below are fixed by means of plurality of bolts 19 such
that when the actuator 7 operates at a particular configuration,
the through-pass-diverter 10 aligns with the inlet-port 3 and the
outlet-port 4.
Similarly, in another position of the actuator 7,
the Movable-part aligns with the opening of the right-angle-
diverter 11 so that conveyed material entering into the inlet-port
3 is diverter to the outlet-port 5 in a right-angle direction.
The through-pass diverter is mounted at its top
with a sealing-device 12a and at its bottom with another
sealing-device 12b. The purpose of the sealing-device is to
provide sealing of the valve such that when the conveyed
material passes from Inlet-port 3 to outlet-port 4, no leakage of
conveyed material takes place in the environment.
Underneath the through-pass-diverter 10, the
right-angle-diverter 11 is mounted as stated earlier, in the same
vertical axis, in order to prevent leakage the right angle
diverter 11 is located inside a diverter protection casing 13. It
will be seen clearly that the right - angle
diverter is bolted to the diverter-casing which in turn is fixed by
bolts with the sealing device 12b
A mounting clamp 14 is fixed at the top plate of
the movable-part The actuator 7 operates through a connecting-
rod 15 which in turn is fixed to the mounting-clamp 14
The sealing-device is detailed in figure 4. The
sealing-device consists of a sealing-holder 16, inflatable-seal 17,
umbilical-ring 18 and fixing-bolts 19. The Inflatable-seal is a
circular hollow member made of special rubber which is fixed
to the sealing-holder by means of umbilical-ring and plurality of
bolts 24 as shown in Section-XX in Figure-5.
The Inflatable-seal is inflated by means of
pressurised air so that perfect sealing is achieved between the
static part and movable part while transporting the conveyed
material. The inflatable-seal is inflated by means of compressed
air from an external source through a nipple 20. The flexible-
tubing 21 for supply of compressed air from external source 24
to the nipple is in Figure-6.
During normal operation of the valve, the
inflatable-seals 12a, 12b remain in the inflated condition. Only
during changeover from through-pass-diverter to right-angle-
diverter or vice versa, these are deflated.
The right-angle-diverter has a stepped surface
which is having a horizontal-surface 22 and a vertical-surface
23. The lower end of the vertical surface is continuous with
the outer end of the next horizontal surface while the upper
end of the vertical surface is continuous with the inner end of
a preceding horizontal surface and there are a plurality of such
integrated surfaces.
The through pass diverter 10 and Right angle
diverter 11 are made of erosion resistant, rust proof and durable
material to ensure longer operating life
The working member of the Diverter-valve is in
its assembled form which is more clearly seen in Figure-2. and
