Definitions
- the presently disclosed subject matter is concerned with a fluid flow control and divert valve and system.
- a blade type valve of the type comprising a shut-off member disposed within a flow path and configured for displacing between a closed and an open, thereby governing fluid flow through said flow conduit.
- valves are referred to at times as ‘fluid diverters’ or ‘shut-off valves’ or ‘blade/knife valves’, ‘edge gates’ or ‘guillotine valves’.
- Valves of the aforementioned type namely ‘shut-off valve’, ‘blade/knife valve’, ‘edge valve’, ‘guillotine valve’, are known and are employed primarily, though not exclusively’ in the field of transfer, dispensing and dosing of loose particle material (e.g. granular material, powder, etc) contained in a hopper and the like.
- loose particle material e.g. granular material, powder, etc
- U.S. Pat. No. 7,309,057 presents a guillotine valve, used for example in pipelines includes a single block body incorporating sealing elements, each in the form of an annular hose section, which are made of an elastomeric material and which are hollow along their entire circumference, each providing an airtight pneumatic circumferential chamber filled with air. Due to the compressibility of the chambers the contact faces of the hose sections deform uniformly in relation to a closing blade. Convex contours on the internal faces of the hose sections result in a further sealing effect due the pressing together of the contact faces by the pressure of the pipeline fluid.
- the hose sections can each also incorporate a T-shaped metal core comprising an axial portion and a radial portion.
- the disclosed fluid flow diverting assembly is a fluid flow diverting system (flow diverter) comprising a mono-block housing configured with at least one fluid conduit, said at least one fluid conduit being selectively open or closed by a blade-type gate member configured with one or more openings and displaceable between at least one open position facilitating fluid flow through one or more of said at least one fluid conduit, and at least one closed position prohibiting fluid flow through one or more of said at least one fluid conduit.
- a fluid flow diverting system comprising a mono-block housing configured with at least one fluid conduit, said at least one fluid conduit being selectively open or closed by a blade-type gate member configured with one or more openings and displaceable between at least one open position facilitating fluid flow through one or more of said at least one fluid conduit, and at least one closed position prohibiting fluid flow through one or more of said at least one fluid conduit.
- a fluid flow diverting system is configured for diverting fluid flow from one or more flow conduits to one or more other flow conduits. Fluid flow can take place in either direction, i.e. fluid flow in one or more conduits can be in one sense whilst fluid flow in other conduits can take place in an opposite sense.
- the fluid flow diverting system is also configured for shutting fluid flow through one or more conduits, regardless of the flow state (open/closed) through other conduits in the system.
- the blade-type gate member is displaceable about a plane transecting said one or more fluid conduits.
- the blade-type gate member is displaceable within the mono-block housing in a sealed type fashion, whereby a sealing arrangement is provided between the gate member and the respective fluid conduits, to thereby prevent fluid leak therebetween.
- mono-block suggests, according to some particular embodiments, that one or more of housing components of the fluid flow diverting system constitute a house component of a fluid treating device (e.g. filtration unit and the like).
- a fluid treating device e.g. filtration unit and the like.
- the housing thereof constitutes part of a housing of a fluid treating device articulated thereto and being in fluid communication with one or more fluid flow conduits of the fluid flow diverting system, and configured for cooperation in conjunction therewith.
- one or more fluid flow diverting systems can be configured for modular configurations, i.e. assembled in series, whereby at least some of the fluid conduits continuously extend between neighboring fluid flow diverting systems and wherein each fluid flow diverting system is associated with a fluid treating device.
- the arrangement is such that each of the fluid flow diverting systems is controlled independently.
- the fluid flow diverting system is used in conjunction with a filtering assembly and it is appreciated that filtering assembly disclosure can be any type of filtering media such as a stack of filtering disks, a filtering screen (i.e. a fine mash of material) or a thread-type cylinder, etc. in the context of a filtering assembly the fluid flow diverting assembly is used for controlling and manipulating (diverting) inlet ports and outlet ports between a filtration mode and a backwash/rinsing mode, for opening/closing respective ports.
- filtering assembly disclosure can be any type of filtering media such as a stack of filtering disks, a filtering screen (i.e. a fine mash of material) or a thread-type cylinder, etc. in the context of a filtering assembly the fluid flow diverting assembly is used for controlling and manipulating (diverting) inlet ports and outlet ports between a filtration mode and a backwash/rinsing mode, for opening/closing respective ports.
- manipulating between the open position and the closed position takes place at a single stroke.
- the blade-type gate member is displaceable within the housing between its respective closed/open positions in a planner fashion, and is thus slidingly received within a slot at the housing. According to a first configuration the gate member is linearly displaceable within the hosing and according to another configuration the gate member is angularly displaceable (rotary) about a pivot point within the hosing.
- the blade-type gate member is displaceable within the housing about an axis substantially normal to the inlet ports and outlet ports and according to a different example the gate member is displaceable within the housing about an axis inclined (slanted) with respect to the inlet ports and outlet ports. It is however appreciated that a combination of the above configurations can be employed with a fluid flow control assembly of the present disclosure.
- the set-up of the inlet/outlet ports and the openings at the gate member can be configured such that a single stroke (linear or rotary) simultaneously opens or closes all ports, whilst according to other configurations the gate member is displaceable between more than one closed and/or more than one closed position, whereby several strokes of the gate member are required.
- the gate member is articulated to a manipulator for displacing it between the respective closed/open positions
- said manipulator can be of any type, e.g. hydraulic, electric, electromagnetic, pneumatic, etc.
- Activating the manipulator is facilitated by a controller generating a control signal.
- the one or more fluid conduits extend within the mono-block housing into a planner gate space defined between two parallely extending wall faces, and defining therebetween a planner gate space, wherein the gate member is displaceable within said gate space.
- the fluid conduits are each configured with a first opening extending at a first wall surface of said gate space and coaxially extending with a second opening configured at an opposite, second wall surface.
- the first and second openings are respective inlet/outlet openings depending on the fluid flow direction within the respective fluid conduit.
- first openings and second openings are configured with a sealing member, e.g. an O-ring, whereby the gate member is displaceable substantially flush over the first openings and second openings, in a sealing tight fashion.
- a sealing member e.g. an O-ring
- the gate space is a gap formed between the first wall surface and the second wall surface of the housing.
- Said gap can be configured by a cut-out portion configured at one or both of said first wall surface and the second wall surface, or within an adapter/spacer member disposed between said walls.
- inserts can be provided between the gate member and the first wall surface and the second wall surface.

Abstract
Provided is a fluid flow diverting system including a housing configured with at least one fluid conduit and being selectively open or closed by a plane blade-type gate member configured with one or more openings and displaceable between at least one open position facilitating fluid flow through one or more of the at least one fluid conduit, and at least one closed position prohibiting fluid flow through one or more of the at least one fluid conduit.
Description
- The presently disclosed subject matter is concerned with a fluid flow control and divert valve and system.
- More specifically the disclosed subject matter is concerned with a blade type valve of the type comprising a shut-off member disposed within a flow path and configured for displacing between a closed and an open, thereby governing fluid flow through said flow conduit.
- Such valves are referred to at times as ‘fluid diverters’ or ‘shut-off valves’ or ‘blade/knife valves’, ‘edge gates’ or ‘guillotine valves’.
- Valves of the aforementioned type, namely ‘shut-off valve’, ‘blade/knife valve’, ‘edge valve’, ‘guillotine valve’, are known and are employed primarily, though not exclusively’ in the field of transfer, dispensing and dosing of loose particle material (e.g. granular material, powder, etc) contained in a hopper and the like.
- For example, U.S. Pat. No. 7,309,057 presents a guillotine valve, used for example in pipelines includes a single block body incorporating sealing elements, each in the form of an annular hose section, which are made of an elastomeric material and which are hollow along their entire circumference, each providing an airtight pneumatic circumferential chamber filled with air. Due to the compressibility of the chambers the contact faces of the hose sections deform uniformly in relation to a closing blade. Convex contours on the internal faces of the hose sections result in a further sealing effect due the pressing together of the contact faces by the pressure of the pipeline fluid. The hose sections can each also incorporate a T-shaped metal core comprising an axial portion and a radial portion.
- The disclosed fluid flow diverting assembly is a fluid flow diverting system (flow diverter) comprising a mono-block housing configured with at least one fluid conduit, said at least one fluid conduit being selectively open or closed by a blade-type gate member configured with one or more openings and displaceable between at least one open position facilitating fluid flow through one or more of said at least one fluid conduit, and at least one closed position prohibiting fluid flow through one or more of said at least one fluid conduit.
- A fluid flow diverting system according to the present disclosure is configured for diverting fluid flow from one or more flow conduits to one or more other flow conduits. Fluid flow can take place in either direction, i.e. fluid flow in one or more conduits can be in one sense whilst fluid flow in other conduits can take place in an opposite sense. The fluid flow diverting system is also configured for shutting fluid flow through one or more conduits, regardless of the flow state (open/closed) through other conduits in the system.
- The blade-type gate member is displaceable about a plane transecting said one or more fluid conduits.
- The blade-type gate member is displaceable within the mono-block housing in a sealed type fashion, whereby a sealing arrangement is provided between the gate member and the respective fluid conduits, to thereby prevent fluid leak therebetween.
- The term mono-block suggests, according to some particular embodiments, that one or more of housing components of the fluid flow diverting system constitute a house component of a fluid treating device (e.g. filtration unit and the like).
- Accordingly, the housing thereof constitutes part of a housing of a fluid treating device articulated thereto and being in fluid communication with one or more fluid flow conduits of the fluid flow diverting system, and configured for cooperation in conjunction therewith.
- Furthermore, one or more fluid flow diverting systems according to the disclosed subject matter can be configured for modular configurations, i.e. assembled in series, whereby at least some of the fluid conduits continuously extend between neighboring fluid flow diverting systems and wherein each fluid flow diverting system is associated with a fluid treating device. The arrangement is such that each of the fluid flow diverting systems is controlled independently.
- According to one particular application, the fluid flow diverting system is used in conjunction with a filtering assembly and it is appreciated that filtering assembly disclosure can be any type of filtering media such as a stack of filtering disks, a filtering screen (i.e. a fine mash of material) or a thread-type cylinder, etc. in the context of a filtering assembly the fluid flow diverting assembly is used for controlling and manipulating (diverting) inlet ports and outlet ports between a filtration mode and a backwash/rinsing mode, for opening/closing respective ports.
- According to a particular design of the fluid flow control assembly, manipulating between the open position and the closed position takes place at a single stroke.
- The blade-type gate member is displaceable within the housing between its respective closed/open positions in a planner fashion, and is thus slidingly received within a slot at the housing. According to a first configuration the gate member is linearly displaceable within the hosing and according to another configuration the gate member is angularly displaceable (rotary) about a pivot point within the hosing.
- According to yet a configuration the blade-type gate member is displaceable within the housing about an axis substantially normal to the inlet ports and outlet ports and according to a different example the gate member is displaceable within the housing about an axis inclined (slanted) with respect to the inlet ports and outlet ports. It is however appreciated that a combination of the above configurations can be employed with a fluid flow control assembly of the present disclosure.
- It is appreciated that the set-up of the inlet/outlet ports and the openings at the gate member can be configured such that a single stroke (linear or rotary) simultaneously opens or closes all ports, whilst according to other configurations the gate member is displaceable between more than one closed and/or more than one closed position, whereby several strokes of the gate member are required.
- The gate member is articulated to a manipulator for displacing it between the respective closed/open positions, said manipulator can be of any type, e.g. hydraulic, electric, electromagnetic, pneumatic, etc.
- Activating the manipulator is facilitated by a controller generating a control signal.
- According to a specific configuration of the fluid flow diverting assembly, the one or more fluid conduits extend within the mono-block housing into a planner gate space defined between two parallely extending wall faces, and defining therebetween a planner gate space, wherein the gate member is displaceable within said gate space. The fluid conduits are each configured with a first opening extending at a first wall surface of said gate space and coaxially extending with a second opening configured at an opposite, second wall surface. The first and second openings are respective inlet/outlet openings depending on the fluid flow direction within the respective fluid conduit.
- The respective first openings and second openings are configured with a sealing member, e.g. an O-ring, whereby the gate member is displaceable substantially flush over the first openings and second openings, in a sealing tight fashion.
- The gate space is a gap formed between the first wall surface and the second wall surface of the housing. Said gap can be configured by a cut-out portion configured at one or both of said first wall surface and the second wall surface, or within an adapter/spacer member disposed between said walls.
- As may be desired, inserts can be provided between the gate member and the first wall surface and the second wall surface. For example, said inserts can be made of a material easier to machine than the mono-block housing.
- It is appreciated, that in any configuration, a fluid conduit can be referred to as an inlet conduit or as an outlet conduit, configured with an inlet port and an outlet port, respectively, depending on the context and the particular application for which the fluid flow diverter is configured to be used.

Thefilter unit 510 is configured with a rawfluid inlet port 540 extending from the mono-block fluid flow diverting system 520 (a partial exploded view of which is provided inFIG. 5C ) into thespace 542 of the filtration assembly. Aninternal space 550 of thefilter unit 532 is in fluid communication with adrain chamber 552 and via adrain tube 556 into afluid collecting chamber 558 of the housing. - Extending from the
chamber 558 there is a filteredfluid outlet port 560 extending through the mono-block flow diverter 520, extending substantially parallel to theraw fluid inlet 540. It is however noticed that the filteredfluid outlet port 560 is configured substantially above the end of thetube 556 whereby thebottom space 558 serves as a filtered fluid accumulation chamber. - It is thus noted that the housing component of the fluid flow diverting system constitutes a house component of the filtration unit. Accordingly, the housing thereof constitutes part of a housing of the filtration unit articulated thereto and is in fluid communication with one or more fluid flow conduits of the fluid flow diverting system, and configured for cooperation in conjunction therewith, as will be explained herein after in further details.
- Configured within the mono-block
fluid flow diverter 520 there is further provided a rinsing fluid outlet port 564 (serving as a drain port) being in flow communication with thespace 542 of the filter assembly. The mono-block flow diverter 520 is further configured with a pressurizedfluid inlet port 568 extending into thechamber 558, the purpose of which to become apparent hereinafter. - Turning now to the mono-block
fluid flow diverter 520 it is noted that the raw tofluid inlet port 540, the rinsingfluid outlet port 564, the pressurizedfluid inlet port 568 and the filteredfluid outlet port 560 extends substantially co-planar within theblock 570 of the mono-block flow diverter 520 and typically said fluid ports extend co-planar and parallel to one another whereby a blade-type gate member 580 is configured in the form of a flat member configured with openings corresponding with the location of said inlet/outlet fluid flow ports, saidgate 580 being articulated to a manipulating piston assembly generally designated 586 being a hydraulic/pneumonic piston or otherwise controlled activator (e.g. solenoid operated and the like) configured for displacing thegate member 580 between a filtration mode (FIGS. 5A , 5B, 5D and 5E) and a backwash/rinsing mode (FIGS. 6A to 6D ). - As can best be seen in
FIG. 5C , thefluid flow diverter 520 is configured with a housing composed of a first block portion 570 (not shown inFIG. 5C ) and the second block portion 517 (being part of the filter unit). Each of theblock portions portion 523A (best seen inFIG. 5E) and 523B (best seen inFIG. 5C ), defining together space fixedly accommodating a pair of made of a machineable material e.g. light metal alloy, plastic material etc. - Each of the inserts/
spacers openings openings second block portion 517, and corresponding openings formed in thefirst block portion 570. Sealing O-rings 575 are provided around each opening between the block portions and the respective insert plate. - A blade gap extends between facing
surfaces spacers member 580, configured withopenings 540′, 564′ and 560′, corresponding with the conduits and openings of the block portions and the inserts, respectively. A set of sealing O-rings collectively designated 575 is provided, received within grooves configured at the static (fixed) inserts 525A and 525B and extending around eachopening gate member 580. - The
gate member 580 is coupled to the manipulating piston assembly generally designated 586, as discussed above. - In the filtration mode, as illustrated in
FIGS. 5A , 5B, 5D and 5E, the rawfluid inlet port 540 and the filteredfluid outlet port 560 are open by virtue of displacement of thegate 580 into its downward position designated byarrowed line 589 whilst the rinsingfluid outlet port 564 and the pressurizedfluid inlet port 568 are sealingly blocked by thegate member 580. - In this position, raw fluid enters in direction of
arrow 592 through the rawfluid inlet port 540 whereby it is forced to flow through thefiltering media 536 in direction of thearrowed lines 594 and then down through thetube segment 556 into thechamber 558 and then out, along the fluid flow path indicated by thearrowed lines 594 through the filteredfluid outlet port 560 from which it is to be consumed via suitable piping coupled to the mono-block flow diverter 520 (not shown). At the filtration mode, the filtered fluid accumulates at thebottom chamber 558 and filtered fluid will remain within thechamber 558 also upon shutting the supply of raw fluid into the system. - Turning now to
FIGS. 6A to 6C , the assembly is illustrated at its backwash/rinsing mode wherein, as mentioned hereinabove, a residual amount of filtered liquid resides at thebottom chamber 558 and upon displacement of thegate member 580 into its upward position as indicated byarrowed line 599 the rawfluid inlet port 540 as well as the filteredfluid outlet port 560 sealingly shut whilst the rinsingfluid outlet port 564 as well as the pressurizedfluid inlet port 568 open, whereby pressurized fluid (pressurized air in the particular example) is forced through the pressurizedfluid inlet port 568, causing the liquid received withinchamber 558 to propel upwards through thetube 556 and viachamber 552 out through thefiltering media 536 in a reverse direction to the filtering mode, thereby rinsing any dirt particles from the filtering media, wherein the rinsing liquid together with the dirt are now forced along the dashedline 611 through thespace 542 and then out through the rinsingfluid outlet port 564. The rinsing fluid flow path is represented by dashedline 609. - Thus, it is appreciated that the liquid filtered during the filtration mode (
FIGS. 5A , 5B, 5D and 5E) accumulated at thebottom chamber 558 serves during the backwash/rinsing mode as the rinsing/washing liquid which is then forced in a reverse direction along the dashedarrows 611 to rinse the filtering media and is then evacuated through the mono-block. - It is appreciated that a fluid flow diverting system according to the present disclosure fluid flow diverting system can be configured for modular configurations, i.e. assembled in series, whereby at least some of the fluid conduits continuously extend between neighboring fluid flow diverting systems and wherein each fluid flow diverting system is associated with a fluid treating device. The arrangement is such that each of the fluid flow diverting systems is controlled independently. For that purpose, the
housing 570 of the fluidflow diverting system 520 is configured with aremovable sealing plate 573, removal of which exposes the fluid conduits of the diverter and further facilitates sealingly coupling of a like neighboring fluid flow diverting system, whereby the fluid conduits of the neighboring systems coextend in a sealing fashion. - Furthermore, one or more fluid flow diverting systems according to the disclosed subject matter can be configured for modular configurations, i.e. assembled in series, whereby at least some of the fluid conduits continuously extend between neighboring fluid flow diverting systems and wherein each fluid flow diverting system is associated with a fluid treating device.

block 604 is fitted with a rawfluid inlet port 650 and a filteredfluid outlet port 652 the latter extending from a drainingchamber 654 being in fluid communication with theinside space 618 of thefilter unit 612. - The mono-block
fluid flow diverter 604 is further configured with a rinsingfluid inlet port 670 being in flow communication with thechamber 654 and further there is provided a rinsingfluid drain port 674 which is in flow communication with theinternal space 614 of the filtration assembly. - It is appreciated that suitable sealing arrangements are provided to prevent fluid leakage, such as sealing gaskets CO rings') 675.
- A blade-
type gate member 680 is slidingly supported within the mono-block housing 605, saidblade 680 is configured with four openings (best seen inFIGS. 7B and 8B , respectively), configured and registered with the respective inlet/outlet ports arrow 689 by means of adisplacing mechanism 690 which is for example a gate displaceable between two extreme positions by a hydraulic/pneumonic valve, an electric solenoid, etc. - It is however appreciated that the number of openings in the blade can be configured depending on different designs and the respective number and positioning of the conduits.
- At the filtration mode of
FIGS. 7A and 7B thegate 680 is displaced in its downwards position as illustrated byarrowed line 689 wherein the rawfluid inlet port 650 and the filteredfluid outlet port 652 are open, whilst the rinsingfluid outlet port 674 and the rinsingfluid inlet port 670 are closed by thegate member 680. At this position, raw fluid enters in direction ofarrowed line 698 through the rawfluid inlet port 650 into thespace 614 of thefilter assembly 602, wherein the raw fluid is forced through the tightly compactedfiltration disks 617 into thespace 618 where it is filtered and allowed to drain, alongarrowed lines 699 into thechamber 654 and then out through the filteredfluid outlet port 652. - Upon displacement of the
gate member 680 into its backwash/rinsing mode ofFIGS. 23A and 8A , the compactingarrangement 624 displaces upwards in direction ofarrow 625 thereby allowing loosening of the filtration disks to facilitate their rinsing and backwashing. Then, upon displacement in direction ofarrowed line 700, the rawfluid inlet port 650 and the filteredfluid outlet port 652 now shut by thegate member 680 whilst the rinsingfluid inlet port 670 and the rinsing fluid outlet port 674 (namely drain port) now open whereby rinsing fluid flowing in direction of dashedarrowed line 702 is forced through theinternal space 618 of thefilter unit 612 and then, through the loosenedfiltration disks 617 out to thespace 614 and from there along the dashedarrows 704 through the rinsingfluid outlet port 674 to a suitable drain. It is however appreciated that the configuration disclosed herein is an example illustrating the association of a fluid flow diverting system with a fluid treating device, in conjunction therewith. It is however appreciated that a plurality of other combinations are possible too. - For example, in connection with the example of
FIG. 7 fluid collecting chamber 558 can be avoided, wherein fluid flow can extend directly fromchamber 552 to filteredfluid outlet port 560
