Specific embodiment

The present invention relates to a kind of equipment that pipeline is flowed through for controlling liquid, method and system, it is by applying Pressure reduction or mechanical external force on shuttle causes it to move in and out in the passage of liquid stream in the duct.

In the de-scription, term " pipeline " is used to include conduit in a general sense, pipe, pipeline, cable channel and passage, its Middle material flows along the length of " pipeline ".Therefore, pipeline can be concrete, steel or plastic material.

The various embodiments of the present invention will be described below by Fig. 1 a -9b.

The valve (10) of the present invention includes pipeline (12) shown in Fig. 1 a, and it could be for conveying material stream (14) Pipeline, such as tubular pipeline, passage, pipeline or cable channel, the material in pipeline can be fluid, for example, oil, liquid, And gas, or solid-liquid fluid-mixing, wherein fluid includes solid in a fluid.The material of transmission is, such as fluid, example Such as, oil, liquid, and gas, or solidliquid mixture body, for example, sewage, solid waste includes wherein solid with other The liquid of thing.Specifically, the present invention is intended to be used in waste collection system, wherein, gas is used to transport solid, and water is dirty Water, industrial gasses and petrochemical industry supply system.Be connected to the pipeline (12) is a hollow protrusion platform (16), example therein It is one and is oriented to the solid arm or flexible duct on ground or any other desired surface by a not permeable transparent cover closing, example Such as sealing device (18).Hollow protrusion (16) accommodates shuttle (20), and it is locked in stop part (22) by clamping device (24) Appropriate location.Clamping device can be magnet or fixture.The position of shuttle as depicted is defined as "ON" position, due to Flowing in pipeline is in maximum rating.It is provided with height-adjustable distance piece to adapt to the depth of pipeline (12) , and distance piece is connected to the stop part (22) of sealing device (18), the change that chamber (28) is under pressure, the chamber (26) (28) it is limited in the volume space in the hollow protrusion (16) between sealing device (18) and shuttle (20).Stop part (22) for permeable, it does not limit the pressure in chamber (28), but limits upwards fortune of the shuttle (20) in chamber (28) It is dynamic.

Fig. 1 b show the pressure reduction for moving down shuttle (20) of generation.Pressure reduction is in pipeline (12) and chamber (28) Pressure between pressure differential, and can be produced by hydraulic pressure or pneumatic means.Can be that oil, the fluid of gas or liquid lead to Excess pressure is introduced in chamber (28).Fluid source can come from the compression conduit of outside positioning, or directly from positioned at chamber The internal pump in room (28), wherein inlet tube is connected to pump.As fluid is entered and filled chamber (28), the pressure in chamber (28) As chamber (28) increases full of fluid, and further introduce fluid into the pressure caused in chamber (28) in chamber (28) Go above the pressure of the material stream (14) in pipeline (12).The power produced by the pressure of the increase in chamber (28) is acted on On shuttle (20), and shuttle (20) is unlocked from " opening " position as shown in Figure 1a by overcoming the resistance of magnet (24). As pressure further increases, the power being applied on shuttle (20) becomes much larger, and shuttle (20) is along hollow protrusion (16) The linear underground of central axis is dropped in pipeline (12).When shuttle (20) is projected into pipeline (12) and reduces the horizontal stroke of pipeline (12) During area of section, the material stream (14) in pipeline (12) is reduced.

Pressure fluid in chamber always pushes shuttle (20) in pipeline (12), the material for blocking in pipeline (12) completely (14) flowing, as illustrated in figure 1 c.Shuttle (20) is entirely confined in this quilt in pipeline (12) in the flowing of material (14) It is defined as " closing " position.

Fig. 1 d show that fluid is removed from chamber (28), which results in the pressure in chamber (28) and get lower than pipeline (12) In pressure.When the pressure in pipeline (12) is more than the pressure in chamber (28), pressure differential produces one and pushes away shuttle (20) Go out pipeline (12) and drive shuttle (20) to leave the power of pipeline (12), and shuttle along the central axis of hollow protrusion (16) Return in chamber (28) towards original " opening " position linearity as shown in Figure 1a.By the fluid in pumping plenum chamber (28) To realize removing fluid from chamber (28).Or, the fluid in chamber (28) can be pumped out by being attached to the conduit of pump.

Fig. 1 e show the design of valve (10), its allow valve (10) with the longitudinal axis of pipeline (12) into any angle Install on vertical direction in the direction of degree.Traditional valve is usually designed with the control machine perpendicular to its flow direction for controlling Structure.When Existential Space is limited, this is probably a problem.The terminal of shuttle (20) is designed such that the size and pipe of terminal The cross section in road (12) corresponds to allow for shuttle (20) to close the cross section of pipeline (12) including the angle including 90 °, its Described in angle (θ) preferably with the longitudinal axis of the pipeline (12) into 40 ° to 90 °.This is in the case of limited space It is helpful, and it is crucial that valve (10) is placed on into special angle or position.

Fig. 2 a show the modification of construction as shown in Figure 1a, wherein bias unit (30) (such as helical spring, flat board bullet Spring or machining spring) it is located between shuttle (20) and retainer (22).This allows a kind of " normally closed " construction, without to chamber Room (28) is pressurizeed so that shuttle (20) is moved into " closing " position as above, because the bias unit with elastic force (30) shuttle (20) is forced into " closing " position.

Fig. 2 b show the valve (10) in " opening " position.In order to shuttle (20) is moved into " opening " position, lead to Cross and extract fluid out from chamber (28) and form the low pressure put on shuttle (20), extract fluid out from chamber (28) and produce Pressure differential, so as to the pressure in the pressure ratio chamber (28) in pipe (12) is bigger, and the pressure differential causes one from pipe Road (12) is applied on shuttle (20) into the power of chamber (28), and its against the force of the spring simultaneously pushes up shuttle, so as to press Contracting bias unit (30) simultaneously allows the material (14) in pipeline (12) to flow.

Bias unit (30) and shuttle (20) may be configured so that shuttle (20) in " normally closed " or " normally opened " setting. In " normally closed " setting, biasing device (30) applies a certain amount of power to keep shuttle (20) to be pushed down, until need by It is lifted with allowing the flowing of material (14).Conversely, in " normally opened " setting, shuttle (20) is in " opening " position Bias unit (30) underhung simultaneously allows the flowing of material (14), until needing by applying higher pressure in chamber (28) Power come reduce shuttle (20) so that the shuttle (20) move in the pipeline (12) with stop material (14) flowing.

Another modification of valve (10) is shown, wherein shuttle (20) is moved by mechanical device in Fig. 2 c.Bias unit (30) for shuttle (20) to be pushed into " closing " position.Cable (32) from " closing " position for moving shuttle to " opening " position Put.Valve (10) uses mechanical device, and a kind of embodiment is capstan winch (34) to wind cable (32) and by shuttle (20) from pipe Road (12) is pulled out and into chamber (28).

Fig. 3 a further illustrate the application of the valve (10) in the case of very depth, in this case, safeguard and When repairing valve (10), its accessibility is necessary, but the condition of the depth or water on liquid or ground may not be caused This safe operation is feasible.In this case, the fluid header in chamber (28) is used for mobile angled shuttle (36), Wherein fluid can be identical or compatible with the fluid of the flowing in pipeline (12), in order to angled shuttle (36) is moved to " closing " position, it is only necessary to apply at the top of fluid header of the little pressure in chamber (28).Angled shuttle (36) Design wedgewise, it allows the direction quilt of the momentum of the fluid of flowing in pipeline (12) along the central axis of hollow protrusion The head of the fluid being delivered in chamber (28).Conversely, in order to angled shuttle (36) is moved into " opening " position, needing The fluid of small size is extracted out at the top of chamber (28), to reduce pressure and allow angled shuttle (36) to travel upwardly.

In fig 3b, angled shuttle (36) drops in the fluid flowed in pipeline (12).In the high volume of fluid During flowing with high speed, the unexpected closing of valve (10) can cause fluid to hammer effect into shape.In order to mitigate such case, pass through Gradually pressure fluid is fed in chamber (28) and the downward power that angled shuttle (36) is pushed pipeline (12) is produced, In fluid being gradually lowered to so as to the shuttle (36) being at an angle of.Due to the work produced by the momentum of the mobile fluid in pipeline (12) For the power upwards on angled shuttle (36), so as to prevent moving downward for angled shuttle (36).By allowing The momentum of mobile fluid is dissipated in the head of the fluid in chamber (28), while be gradually lowered angled shuttle (36) entering " closing " position, can minimize

Fig. 3 c show the angled shuttle (36) in " closing " position, and the flow of fluid in pipeline (12) is stopped Only.Using the setting, it is not necessary to additional damper or pad, to allow pipeline (12) in flow of fluid be diverted to subtract Lighter fluid hammers effect into shape.In order to allow flowing of the fluid in pipeline (12) again, as shown in Figure 3 d, fluid is needed by from chamber (28) remove in.This causes the pressure in chamber (28) to become less than the pressure in pipeline (12), will be angled so as to generate Shuttle (36) power of " opening " position that lifted and entered into chamber.

Fig. 4 a-4d show the application using shuttle (20), and shuttle (20) is as a kind of device by shuttle (20) Produce pressure differential to stop material stream (14), wherein shuttle (20) is always away from the side of larger pressure, the larger pressure Generate the power acted on shuttle (20).In fig .4, shuttle (20) is in " opening " position.Fig. 4 b are shown when fluid quilt When being fed in chamber (28), due to by the pressure in chamber higher than pressure in pipeline acting on shuttle for producing Power, shuttle (20) is pushed down.In Fig. 4 c, the downward power produced due to the elevated pressures in chamber (28) causes to slide Shuttle (20) is maintained at " closing " position.When fluid is removed from chamber (28), as shown in figure 4d, the pressure in pipeline (12) becomes More than the pressure in chamber (28), and pressure differential generates the power for moving up shuttle (20).

Fig. 5 a-5d are shown with the outside shuttle for installing air bag (38).In fig 5 a, the pressure in chamber (28) is less than Pressure in pipeline (12), and the shuttle with air bag (38) is in " opening " position, wherein due to pressure differential, air bag cladding In shuttle and in the state without expansion.

In figure 5b, the chamber (28) that the fluid under pressure is entered above shuttle, causes to be produced in chamber (28) Higher pressure.The pressure for coming from the chamber (28) above the shuttle with air bag (38) is allowed to pass through shuttle and enters Enter air bag (38).Fluid permeability passes through shuttle, and the power from increased pressure to act on airbag wall.Higher pressure differential Shuttle with air bag (38) is pushed the power in pipeline (12) for generation, and the power causes the shuttle with air bag (38) slight Expansion.

In fig. 5 c, the power for being produced by the elevated pressures in chamber (28) relative to pipeline (12) will be with air bag (38) Shuttle push " closing " position, wherein air bag expand completely with seal be likely to be present in shuttle shuttle body and pipeline (12) wall it Between gap, so that it is guaranteed that the effective Fluid Sealing between the both sides of the pipeline (12) separated by the setting of shuttle-air bag.

As fig 5d, by pumping out fluid from chamber (28) and removing fluids, produce in chamber (28) relatively low Pressure.This relatively low pressure differential causes air bag to shrink with the power of the elevated pressures in pipeline (12), and the power is upwards Act on air bag towards chamber, while the shuttle with air bag (38) is upwardly into chamber (28) with restorer fluid (14) flowing in pipeline (12).

Fig. 6 a-6d show the modification of the shuttle with semi-solid and half airbag design (40).In this design, only shuttle The half of body is permeable, and to allow fluid permeability to air bag, and second half of shuttle is solid.Half inflatable balloon-like shuttle (40) Solid side is oriented such that towards the upstream side of pipeline (12), and air bag side is towards the downstream of pipeline (12).Can set Think it is this be configured to, when conveying solid substance material in a fluid, because the solid portion of the shuttle of upstream side will protect air bag Do not pierced through by the solid material in fluid-solid mixed flow.The method of valve (10) is opened and closed similar to institute in Fig. 5 a-5d The method shown.

In Fig. 6 a, half inflatable balloon-like shuttle (40) is in " opening " position, wherein pressure of the cell parts in chamber (28) Shuttle is coated during the pressure that power is less than in pipeline (12).In figure 6b, the fluid under pressure enters chamber (28) and wears Cross shuttle and penetrate into air bag side.The increase of pressure generates and half inflatable balloon-like shuttle (40) is pushed down into pipeline (12) Power, the power causes air bag somewhat to expand.In fig. 6 c, the pressure in chamber (28) is the pressure being sufficiently higher than in pipeline (12) Power, by half inflatable balloon-like shuttle (40) " closing " position is moved to, and causes air bag side to expand to seal any completely Gap.As shown in fig 6d, the lower pressure from chamber (28) removing fluids, chamber (28) causes air bag to shrink.Half inflatable balloon-like is slided Shuttle (40) is applied power thereon and is increased in chamber (28) due to the elevated pressures in pipeline (12), so as to recover in pipe (12) flowing of fluid (14) in.

Fig. 7 a show the top view of the shuttle with hollow space (42).This design is the cunning for being equipped with air bag Shuttle.Air bag is circumferentially arranged on around shuttle (20), and by the spiritual consistent material such as rubber with the present invention, neoprene rubber Glue, leather and other elastomeric materials are made.In the case of using half inflatable balloon-like shuttle (40), shuttle is not allowed to perpendicular around it Straight axis rotate, and a kind of device for preventing shuttle in the angled rotation of within the chamber, such as gathering sill (44) are attached to shuttle On, the gathering sill coordinates with the tongue (45) being formed in hollow protrusion (16), as shown in Figure 7b.According to circumstances, it is oriented to Groove (44) can be formed in hollow protrusion, and tongue (45) is formed on shuttle.Fig. 7 c are shown with around shuttle body wall Hole (46) shuttle, it will allow fluid from shuttle so that air bag is according to the chamber above the hollow space of shuttle and its Interior pressure condition and expansion or shrinkage.When the pressure of within the chamber is more than the pressure in pipe, air bag will expand, and work as within the chamber Pressure less than pressure in pipeline when, air bag will shrink.

Fig. 8 a show the top view and side view of the hollow shuttle with inflatable side seal (48).Inflatable side seal Part (50) is made up of the material similar with the air bag described in Fig. 5 a-5d.Inflatable side seal (50) is retracted into and is formed at cunning In recess on the surface contacted with duct wall of shuttle.Gathering sill (44) prevents the shuttle with inflatable side seal (48) from existing Within the chamber rotates, to guarantee appropriate sealing fluid.When the positive differential pressure not being fed in chamber, side seal (50) is in Contraction state and holding be retracted in recess.Fig. 8 b show the top view and side view of same shuttle, and the shuttle has band There is the inflatable side seal (48) of side seal (50), the side seal is filled when positive differential pressure is fed in chamber Gas.Side seal (50) expands to seal any small―gap suture being likely to be present between shuttle and duct wall.The motion of the shuttle Mode is similar to as shown in Fig. 5 a-5d.

Fig. 9 a and 9b show the screw thread being formed on the top of shuttle (20) and the shuttle with air bag (38,40) (52), in order to remove from hollow protrusion shuttle (20) or with air bag (38, shuttle 40).In shuttle (20) and band Have air bag (38, the installation of shuttle 40) or maintenance period, when it is inserted into hollow protrusion or is moved from hollow protrusion Except when, extendible T-shaped spanner or play the device with the end of thread of similar effect and be screwed onto on screw thread (52) to grip cunning Shuttle (20) or the shuttle with air bag (38,40).Be fully inserted into when shuttle (20) and the shuttle with air bag (38,40) or After removing, by shuttle (20) or with air bag, (38, shuttle 40) is backed out from extendible T-shaped spanner.

The design of the valve is the improvement of the conventional valve equipment to using at present.The circular cross section of shuttle is preventing it With increased mechanical strength during flowing, and compared with traditional gate valve or ball valve, valve of the present invention much more resistant to by The deformation that power thereon causes is acted in material stream and differential pressure, traditional door or ball valve are used and have the flat of relative thin Flat cross section.

Additionally, the installation of valve only needs to be formed at the top of main pipeline opening to be attached hollow protrusion.Without prominent Material flowing or cause material to be captured that right depression or angle is come in interrupt pipe.Pipeline is from upstream side to downstream Smooth hole.Hollow bumps are also smooth hole, and in this place it is joined to the opening on surface with supervisor, and this design is allowed respectively Plant device and move the within the chamber of shuttle to be used in hollow bumps.Without the material that unexpected depression or angle are come in interrupt pipe Stream is dynamic or causes material to be captured.Pipeline is the smooth hole from upstream side to downstream.Hollow protrusion is from it with supervisor's The part of the opening on joint to its surface is also smooth hole, and the design allows various devices to move in hollow protrusion The shuttle that the interior in portion uses.

Due to the design of valve, any maintenance needs to chamber are eliminated, because all of installation and maintenance can be from ground Carry out on face.This eliminates the needs to outside machinery or safe ventilation equipment, and this contributes to reducing installing and safeguarding valve institute The cost for needing.Further, since dirt need not be removed on a large scale, it is possible to reduce the risk being related in these courses of work and peace The use of full device.

Conventional valves design is a kind of overproof design, can withstand up to 1,000,000Pa operating pressure.This is needed The engineering of complexity and the material of higher intensity are wanted, the higher costs of valve are this often means that.As described in the present invention valve can To be applied to the system with relatively low operating pressure, i.e. the up to system of 500,000Pa, therefore its simple design and to high-strength The needs of degree material less need for and need relatively low cost.

Present invention could apply to there is the situation of oil-well blowing, wherein the side of the pipe that can gush out in oil is opened Mouthful, and can by shuttle insertion opening with stop from oil-gas Layer it is any more oil flowings.This mode is than inciting somebody to action In " well killing fluid " insertion oil well more preferably, in the well for adding well killing fluid, if well will be used again, need to remove kill-job Liquid.
