Description

The annex of band pressure exchanger equipment

The present invention relates to a kind of annex, especially the annex that has the pressure exchanger equipment of the tube chamber that alternating current crosses, wherein be furnished with in the enclosure one have a plurality of flow channels can rotating control assembly, shell has the interface of a plurality of connecting lines, shell and one first pipe-line system, and be connected with at least one tube chamber end face separately, wherein tube chamber another end face separately is connected with one second pipe-line system under the switching of other annex, control assembly is equipped with a motor-driven power transmission shaft, and the flow channel of control assembly alternately is connected with the opening of arranging in shell.

This pressure exchanger is made up of two or more tube chambers, and annex is equipped with in its end.Open and close accordingly by annex, tube chamber alternately loads with the liquid that contains different-energy.Therefore in tube chamber, in equipment or in equipment operation process, a kind of high pressure of liquid can pass to another liquid that only has slight pressure.Therefore can save cost of energy in the equipment by means of this pressure exchanger, and booster pump can do littler.

Reverse osmosis is through being usually used in the processing of water.By a film system, when fluid flow was big, the film system will be made up of a large amount of membrane modules liquid stream wherein to be purified with high-pressure extrusion.Because always have only the part of liquid to be purified can flow through diaphragm, so in this membrane module, can realize separating of pure water and the concentrate that gathers by diaphragm.The part that flows through perhaps also can be used as the penetrant at the diaphragm opposite side as pure water, as utilizing part to flow out.The part that does not flow through is as saline solution, and a kind of liquid concentrate that is gathered by salt and mineral matter leaves membrane module as part unavailable and that be under the high pressure.Under the membrane module inlet pressure of about 65 crust, this pressure is probably at 2 crust.

By US5306428 reverse osmosis equipment has been well-known, wherein reclaims the pressure exchanger that has used under the tube chamber form for energy.By means of its help, be delivered on the liquid of still preparing purifying by the also higher pressure of the saline solution that flows out in the membrane module, be rich in energy.Therefore in order to produce for the essential high pressure of reverse osmosis, the degree along with pressure improves only needs a small pump driving power for the liquid of supplying with.

Except other annex, annex that has a rotating control assembly is used to control and/or change and enters and from the fluid passage of the saline solution of pressure exchanger.By means of its help, realize using the saline solution of discharging, to alternately loading of pressure exchanger tube chamber by membrane module.Rotating control assembly is a cylinder, wherein according to the arranged in form interface channel of a three-way cock.In transfer process, realize thoroughly closing of all fluid passages.Compression shock for fear of in this class transfer process is furnished with pressure equalisation passage in cylinder.

In the service life of depending on diaphragm, its separating power descends, and therefore liquid to be purified must correspondingly stay in membrane module the longer time.Owing to this reason, under prior art, influence the conversion time of cylinder by means of a servo motor.Yet this annex only is suitable for little reverse osmosis equipment, because the cross section of flowing through in annex is almost the same big with the cross section of flowing through for the treatment of flow in pipes.In main equipment, and the liquid column that moves therein, and consequent power, produce the physical dimension problem of very big annex.

Task of the present invention is, especially develops a kind of conversion equipment for large-scale reverse osmosis equipment, and by means of its help, the liquid streams a large amount of in simple mode can distribute between the different tube chamber of pressure exchanger by interference-free.In the annex of this class, the solution of this problem is to realize in the enclosure by the inflow to control assembly of axial and/or radial direction, and realizes by the outflow of control assembly along axial direction.When axially flowing into and flowing out, can obtain the minimal structure length of annex.Otherwise though annex is a little long when radial inflow, yet the easier control of the axial displacement that is produced.

Task of the present invention is finished by following annex: the annex that promptly is used for the fluid passage conversion, it is used to have the pressure exchanger equipment that is provided with the tube chamber that alternating current crosses, wherein in a shell, be furnished with one have a plurality of flow channels can rotating control assembly, shell has the interface of a plurality of connecting lines, wherein shell is connected with first pipe-line system, and be connected with at least one pressure exchanger end face separately by interface, wherein pressure exchanger another end face separately is connected with second pipe-line system under the transfer of other annex, control assembly is equipped with a motor-driven power transmission shaft, and the flow channel of control assembly alternately is connected with the interface of arranging on shell, and the position of the switch along with control assembly, the highly pressurised liquid that flows into replaces flows to pressure exchanger, and arrive the interface that flows out low pressure liquid by the low pressure liquid that pressure exchanger flows out, wherein, be furnished with the interface of the highly pressurised liquid of an inflow, interface and at least two the pressure exchanger interfaces that alternately load that flow into low pressure liquid with highly pressurised liquid and low pressure liquid, realize in the enclosure by the inflow of axial and/or radial direction to control assembly, and realize from control assembly in axial direction to the outflow of the low pressure liquid of low pressure liquid interface, and in the control assembly transition period, give with annex and be in of the high pressure loading of effective tube chamber that is connected with inlet opening, on control assembly, compare with the flow openings of corresponding to shell therewith at the control opening of the area arrangements of high pressure chest, have an other opening angle.

A scheme is, control assembly is made the control assembly of a hollow cylinder, and dividing plate is divided into the control assembly of hollow cylinder in the chamber in two different pressures districts.In annex, can form chamber additional, that produce the flow divert for the treatment of exchanging liquid with this.Therefore use the thin wall component of simple, an easier control in transfer process for the original control of annex and sealing function.Here another scheme is, arranges additional reinforcement in the chamber in different pressures district.This reinforcement can be made the reinforcement gusset, perhaps makes the thin-wall part that distributes along flow direction for the pressure area that flows through.Same additional reinforcement also can be made annular element.It can be sector or annular element.It improves the rigidity of hollow cylinder control assembly, when being in different following times of pressure condition, the distortion of resisting parts thus.

The different schemes that is used for the operation of hollow cylinder control assembly is, power transmission shaft adopts with dividing plate can transmit being connected of moment of torsion, baffle arrangement is in the mesozone of hollow cylinder control assembly, the arrangements of components that can transmit moment of torsion is on an end face of hollow cylinder control assembly, and dividing plate is fixedlyed connected with control assembly or dividing plate is fixedlyed connected with shell.What therefore power transmission shaft can be direct or indirect is fixed on the control assembly, and it depends on best processing mode.When the zone line of baffle arrangement, guaranteed the distribution in two pressure chambers at the hollow cylinder control assembly.The dividing plate that meanwhile control assembly is divided into two pressure areas can directly be fixed on the control assembly, perhaps is connected with shell.

This scheme is in high-pressure side inlet opening district for this reason, and dividing plate is fixed on the shell with support bar.Meanwhile seal can be arranged between static dividing plate and the rotating hollow cylinder control assembly inner wall surface.Dividing plate and/or the dividing plate that has a support bar that links to each other with shell also can be made interchangeable parts, and it makes that installation and maintenance work is easier, and fixing dividing plate makes axially moving freely of control assembly be arranged as possibility on shell.

According to another kind of scheme, control assembly is a solid cylinder, and a plurality of flute profile flow channels constitute the different pressures district on its circumferential surface.This manufacturing type has been improved strength characteristics.Another kind of for this reason scheme is that on circumferential surface, the flow channel of same pressure area is obtained the balance of pressure thus mutually in radially relative layout.

The cross section of a flute profile flow channel that links to each other with flow openings has formed the control opening of control assembly in addition, and in a high-pressure side inlet opening zone radially, is arranging a cannelure on the shell and/or on the circumferential surface at control assembly.Obtained thus preferably, additional radially connection possibility.In addition on control assembly, between the end of the flute profile flow channel in different pressures district, be furnished with the ring packing district of sealing, and, be furnished with seal on the control assembly and/or on shell in the zone of seal area.And be implemented in the axial displacement unloading between its end face by a relief passage that is arranged on the control assembly.Therefore additional thrust bearing is unnecessary.

The pressure loading of shell is by constituting fork-shaped and/or step-like on the outer circumference surface of control assembly, and the control flume that is connected with the control opening and optimised.In order to resist the load on the outer enclosure, therefore realize autotelic, as to have a high pressure enclosure pressure loading in the zone of control flume.The subsidiary control flume that passes through has obtained an other flow channel, makes the instantaneous possibility that is connected to become between the tube chamber that connects by means of its help.Therefore a cross section of overflow ducts is instantaneous transferring on the control assembly.

When control flume adopts fork configuration, subcontinuous volume flow and pressure condition in annex, have been kept in the transition period.The arcuate member that is in the original Y-piece is arranged in the plane of radially strengthening gusset.This measure has improved the transmission of the power in annex equally.Similarly also can arrange on the inner peripheral surface of wall in the enclosure that constitute fork-shaped and/or step-like, and the mobile groove that is connected with flow openings.

Another kind of scheme according to the present invention on the outer wall of shell and/or in be furnished with the overflow ducts of a plurality of connection flow openings.Help by means of it realizes the exchange of liquid from the tube chamber to the tube chamber during the working cycles of pressure exchanger, wherein annex ensured each connection tube chamber always from the filling of influent zone, and discharge from the trickle zone.For the coupling in pressure exchanger control time, the flow openings of arranging constitutes the part of an adjustable hollow cylinder outer casing inner wall in the enclosure.This additional hollow cylinder outer casing inner wall is made independent parts, and can reverse layout with respect to shell with the flow openings of arranging inside.Therefore under the situation of needs, can mate with the overlapping time of the control opening of on control assembly, arranging.It carries out may be at run duration or at the annex load facility time according to project organization.

In the outer wall of shell, be furnished with a plurality of inlets in addition.Its feasible manufacturing and processing are easier when cast casing.It by the method known with the form of locking member such as embolism, screw element or similarly parts seal.In the outer wall of shell, be furnished with the reinforcement of a plurality of outsides for the rigidity that improves shell.It can be arranged to around shape or externally shell groove just.Because weight and processing, the shell groove is arranged between the overflow ducts.

The tube chamber of pressure exchanger can instantaneously interconnect by overflow ducts during control assembly moves in addition.Particularly when during as attached flow openings, realizing the conversion of impacting with minimum pressure by another angular area expansion at high-pressure side control opening.Angle between opening is measured like this, so that when the opening of tube chamber 1 is just in time closed, and the mobile end of high-pressure fluid, the opening of tube chamber 2 is just in time opened, and admits high-pressure fluid thus.Guaranteed still to wait liquid to be purified and that be in the tube chamber opposite side always to be under the high pressure thus.

Overflow ducts also can be an outer tube, wherein for easy installation, distributes on the outer circumference surface of shell and arranges a plurality of pipe fitting interfaces.According to another kind of scheme, overflow ducts is the flow channel that is integrated in the shell wall.It has reduced the quantity of sealing station.

Another kind of scheme is, by minimum two mutual radially relative flow openings separately, and the control corresponding opening is implemented in fluid exchange between control assembly and the overflow ducts therewith.The symmetric arrangement of opening and flow channel has obtained the supporting that freely moves radially of control assembly in the enclosure.

For soft commutation, the control opening of hollow cylinder control assembly for example can be slot, polygon or other form.The size of position on control assembly and control opening makes no compression shock flow and is converted into possibility.Closing simultaneously of the tube chamber control opening of a connection links with another opening mutually of opening of control of other tube chamber of closing previously, and vice-versa.Because the control opening that enlarges,, realized overlapping with the flow openings of the overflow ducts of fixed and arranged on shell perhaps exactly by its position on control assembly.Meanwhile this overlapping state to commutation and the flow fluid scapus that is influenced thus produces advantageously effect.

At the run duration of annex, on the circumference of control assembly, in graded area, exist different pressure states.Move easilier for the conversion that makes control assembly, control assembly can be provided with a plurality of relief passages on excircle.The zone of determining with this slidingsurface can load with the back-pressure of determining.This class relief passage also can be arranged on the outer wall surface of control assembly, and/or is arranged on the annex case surface that is in face-to-face position.According to its shape and structure, in relief passage, can realize continuous or flowing through of replacing.

When control assembly is bearing on the tortuous case surface of moving towards pivotally, perhaps when the outer casing inner wall as separate part is bearing on the tortuous case surface of moving towards, can obtain a kind of favourable processing possibility.Tortuous groove has constituted a kind of affluent channel between the tributary so, and it works in the enclosure as overflow ducts simultaneously.Therefore this shell can be with low-down expense manufacturing, because avoided disadvantageous undercut thus.Same control assembly can be on a plurality of independent surface of shell pivoting support.

Only when one of use has the control assembly of stationary barrier, be provided with the thrust bearing of supporting control assembly in the enclosure.Control assembly for a high-pressure side forms between two stationary barriers does not need thrust bearing in principle.In a kind of modification in back, show, arrange that on shell the annular chamber that is connected with the high-pressure side is favourable.It allows to carry out better simply sealing at interface area.

Another kind of scheme is that shell is provided with the interface that is used to connect each tube chamber, and is provided with the interface of high-pressure side inlet opening and the interface that low-pressure side flows out opening separately.Therefore the sealing station quantity on annex can drop to minimum.Wherein shell can be provided with one axially and/or the high-pressure side inlet opening of radial arrangement.An axial arranged inflow entrance is opened on the end face that is arranged in shell, and wherein first pipe-line system is arranged on this on high-tension side inlet opening.This structure with simple mode make that the sealing of annex becomes easily because only need the sealing of a static state here.

Another kind of for this reason scheme is that the high-pressure side inlet opening is auxiliary arranges the flow divert device with support member, and the flow divert device just surrounds a bearing of control assembly.This measure helps the shortening of part length and the improvement of rigidity equally.And be arranged on the outer cover owing to have the high-pressure side inlet opening of flow reversing arrangement and supporting, in the possibility of simplifying processing, improved the supporting of control assembly.

Same shell can be provided with and have axially and/or the low-pressure side of radial arrangement outflow opening.

Embodiments of the invention are described in the accompanying drawings, and will further specify below.As shown in the figure

The operation principle of annex has been described on the example of reverse osmosis equipment according to prior art in Fig. 1.High-pressure pump 1 carries liquid to be purified to one or more reverse osmosis membrane assemblies 2, normally lake water, seawater, river bend water or also can be waste water.Osmotic pressure owing to high in membrane module 2 produces separating effect in the film of Bu Zhiing therein.Have purifying waste water of low pressure in the outflow of the back of film, promptly so-called penetrant is collected the back and supplies with other application.

By the unpurified liquid that flows out in the reverse osmosis membrane assembly 2, promptly so-called saline solution after separation process, has the concentration of higher harmful substance, and harmful substance is salt normally, and is flow back to the original place.Because it is with the high energy content of pressure energy form, for energy reclaims, saline solution imports the pressure exchanger in one two chamber by an annex 7.In tube chamber 3.1,3.2, be furnished with under pressure influence movably separator piston 4.1,4.2, it has formed at two separately with the isolation of the cavity of different pressure-loaded.The equipment that has no separator piston tube chamber also is well-known, yet when system was no longer mated by bascule or control time, can cause undesirable mixing between the different liquids inside.

Meanwhile the high pressure of saline solution is pressed on piston 4.1 in first tube chamber 3.1 that is in top shown in Fig. 1 to a side that is in away from annex 7, and transmit pressure everywhere inside and be on the liquid of piston opposite side.Meanwhile high pressure is passed to and is in piston left side and also waits on the low liquid of pressure to be purified.This liquid flows to the left side in upper tube chamber 3.1 with high pressure then, and flows through the check valve 5 of the booster 6 that is arranged in second pipe-line system.Also needing to compensate the small pressure that produces by means of 6 of boosters in the infiltration purification process in membrane module 2 then falls.Because reclaiming 6 of boosters, energy also needs to be provided at the pressure differential that reverse osmosis membrane assembly loses.Therefore high-pressure pump 1 can be very little, and therefore become cheaper than the cost of equipment when not having energy to reclaim.

When in first tube chamber 3.1, when piston 4.1 arrived the tube chamber end, annex 7 switched then, and therefore first tube chamber and atmosphere are connected from now on.Inlet pressure in the intake line of guiding to main pump 1 is enough, with liquid to be purified, being in the saline solution that reduces pressure now in the first top tube chamber 3.1, again by extrusion to the right in the top tube chamber 3.1, and makes one in line in atmosphere.During the process that saline solution is discharged in by first tube chamber 3.1, simultaneously by annex 7, the loading of bottom second tube chamber, 3.2 usefulness high pressure saline solutions.The discharge process of decompression saline solution is described in second tube chamber 3.2 of bottom.

Periodic conversion by corresponding annex 7 realizes that the alternative pressure of two tube chambers 3.1,3.2 loads, and realizes that therefore effective energy reclaims.Because the threeway function in annex may produce compression shock in transfer process, it can damage the diaphragm in the reverse osmosis membrane assembly 2.For making this danger drop to minimum, for this purpose is provided with additional special pressure equalisation openings in the control assembly of annex 7.By adjust during moving in conversion, uncompensated radial displacement meeting brings other rough sledding.

In Fig. 2, by show the cross section A-A and the B-B of two interlaced 90 ° of layouts according to a cross section of annex of the present invention.By means of its help, in ensuing description of drawings, the operation principle of annex is explained.Four-headed arrow Z has shown here by coming in (not shown) pressure exchanger tube chamber and flow direction in the pressure exchanger tube chamber; Single arrow Y has shown the discharge direction by the decompression saline solution that flows out in the annex.

Annex according to the present invention is represented in the section of two interlaced separately 90 ° of layouts in Fig. 3 a and 3b.Fig. 2 is taken from the position of cross section A-A and B-B, and remains constant in the position of the cylindrical control assembly 10 of description of profile hollow core.

Hollow cylinder control assembly 10 is arranged in the shell 11 of annex pivotally.Flow out by reverse osmosis membrane assembly 2, be in the saline solution under the high pressure, be called high pressure saline solution (HPB) below, and,, enter a high pressure chest 14 of annex by a unique high-pressure side inlet opening 12 by means of a gatherer that (not shown) is preposition.This example has represented that an annex is similar to being connected of two-tube pressure exchanger shown in Figure 1 with one.Owing to this reason has been abandoned being connected to describing of tube chamber on the annex.

The shell 11 of annex has two

interfaces

16,17 on outer wall 15, (not shown) pipeline that is used to connect same not shown tube chamber 3.1,3.2 just is connected on the top.The embodiment of shell 11 is provided with all-in-one-piece flow channel 18-21 and two

ring cavities

26,27 here, is implemented in

interface

16,17 and is arranged in the connection between the flow openings 29-36 on the outer casing inner wall 28 by means of their help.Here because structural reason is a hollow cylinder thin wall component, it is arranged in the shell 11 outer casing inner wall 28 hermetically.When it for example made a cast structure, it can be a fixing building block of shell 11 equally.28 whiles of outer casing inner wall are as the radial support of hollow cylinder control assembly 10.The wall of control assembly 10 is passed by a plurality of control opening 37-44.

Shown in Fig. 3 a, enter the high pressure chest 14 of shell 11 by inlet opening 12 by a represented high pressure saline solution of arrow HPB.High pressure chest 14 is arranged within the control assembly 10, and fixedly end face 13 and a dividing plate 47 fence up along axial direction by shell.Dividing plate 47 seals with respect to control assembly 10 by means of seal 49 in the present embodiment.And dividing plate 47 particularly is connected with end face 13 antitorque commentaries on classics here by support bar 48 and shell 11.By this project organization, can during its converting motion, alleviate axial compressive force by rotating control assembly 10.Can find the application scheme of knowing for seal 49.

In control assembly 10, compare here in the enclosure at the control opening 37-40 of the area arrangements of high pressure chest 14 that corresponding to therewith

flow openings

30,31,34,35 has other opening angle on the wall 28.Selection by the suitable openings angle can realize, in the transition period of control assembly 10, is in effective (not shown) tube chamber that is connected with annex here by

interface

16,17, can instantaneously be in simultaneously under the high pressure of inlet opening 12.Therefore the pressure oscillation that endangers the reverse osmosis equipment film has been avoided.

Control assembly 10 can turn round layout in shell 11.The dividing plate of fixing with support bar 48 antitorque commentaries on classics on shell 11 47 approximately is in the zone line of shell.Dividing plate 47 has become control assembly 10 internal distribution to have two

chambeies

14,45 in different pressures district.What chamber 14 here continued is connected with the higher-pressure region HPB of membrane module.Opposite another chamber 45 that in Fig. 3 a, is in dividing plate 47 left sides, with that represent by arrow LPB, decompression, be connected by an interface 46 of the low-pressure area of the saline solution that flows back in the tube chamber.Because control assembly 10 relatively moves for dividing plate 47, so be provided with a seal 49 that is fit to for the pressure condition of sealing.

Control assembly 10 drives by a power transmission shaft 50, and its end is protruding by the through hole 52 on the shell of low-pressure side.Gyration can be continuous or stepping, and speed will depend on that remaining system unit determines.

When the position of control assembly 10 does not change, as follows in the operation principle shown in Fig. 3 a and the 3b according to convert attachments of the present invention:

By axial arranged here unique inlet opening 12, high pressure saline solution HPB flows into high pressure chest 14.This structure decrease the quantity of interface and the cumulative volume of annex.Certainly the supply inlet opening 12 of high pressure saline solution HPB also can radial arrangement, yet the structure of annex just must be longer, and supply must can't realize that control assembly 10 overlapping shell region carry out.Low pressure saline solution LPB from annex is discharged by interface 46.Annex guaranteed basically, from interface 16 and tube chamber that 17 are connected a tube chamber is arranged all the time with the filling of high pressure saline solution, then from the another one tube chamber, the low pressure saline solution of decompression is drained.Only instantaneous two tube chambers in the transition period obtain high pressure simultaneously.

First kind of duty (Fig. 3 a and 3b):

High pressure saline solution HPB is by high pressure chest 14, by in control assembly 10, being in the

control opening

38 and 39 of face-to-face position mutually, the control opening 30 and 31 that is in face-to-face position in the enclosure in the wall 28 equally mutually flows into the annular chamber 27 that is integrated in the shell 11, comparison diagram 3b.Two dividing

plates

24,25 that partly surround annular chamber 27 along axial direction have formed the supporting of outer casing inner wall 28 simultaneously.High pressure saline solution HPB flows to one first tube chamber interface 17 from annular chamber 27.Remaining is in annex, formed annular chamber 26 and interface 16 flow channel,

passage

20 and 21

flow openings

34,35, be closed by control assembly 10.Filled with this first tube chamber that is in interface 17.

Be in effective the connection by interface 16 annexes with two other tube chamber simultaneously.Be back to annex from the low pressure saline solution LPB that second tube chamber, reduces pressure here, and enter annular chamber 26 by interface 16, and by the

flow openings

33 and 36 that is in face-to-face position mutually, and, enter low-pressure cavity 45 by in control assembly 10, being in the

control opening

41 and 44 of face-to-face position equally mutually.Flow into an interface 46 from that low pressure saline solution LPB that comes out, realize the emptying of tube chamber thus to atmosphere one side.Arrange on all other the wall in the enclosure 28 that guide

channel

The high pressure saline solution that flows into first tube chamber by interface 17 with its pressure energy pass to be positioned at the inside still wait to be purified, and then be pressed into the liquid of reverse osmosis membrane assembly with higher pressure.The selection in the opening cross section of the speed of gyration of drive unit on power transmission shaft 50 (not shown) and control opening 37-40 has guaranteed that in the moment of tube chamber before being filled with by the high pressure saline solution fully at interface 17 places, injection process finishes.The discharge process of while at second tube chamber at interface 16 places finishes equally.

That concur in pairs separately in the high-pressure side and be in the opening 38/30 and 39/31 of face-to-face position mutually, however than the time of opening at the paired opening 41/33 and 44/36 of low-pressure side to keep long a bit.Thus when paired opening 38/30 and 39/31 is just in time closed, the tube chamber that at this moment is in interface 16 places by paired opening 37/34 and 40/35,

passage

20 and 21 and annular chamber 26 obtained high pressure.Therefore guaranteed that second kind of duty begins along with the change of the flow direction that arrives tube chamber under no compression shock.

Second kind of duty (Fig. 4 a/4b):

Opposite with shown in Fig. 3 a and the 3b represent at the half-twist in shell 11 of control assembly 10 shown in this accompanying drawing, and the mobility status to tube chamber is opposite fully at

interface

16,17 places.In order better to see clearly, abandoned during rotatablely moving diagram to middle position.

When paired opening 38/30 and 39/31 was in the closed position, the tube chamber of at this moment annotating so continued filling at interface 16 places.On the contrary at the tube chamber at interface 17 places,, be in the

passage

18 and 19 and the paired opening 29/42 and 32/43 that is in face-to-face position mutually of face-to-face position mutually, by low-pressure cavity 45 and interface 46 emptyings by annular chamber 27.When the tube chamber at interface 17 places was drained, the pressure energy of high pressure saline solution HPB was delivered in the tube chamber at interface 16 places under second kind of duty.When finishing, be similar to first kind of duty in process, paired opening 37/34 and 40/35 and 38/30 and 39/31 is instantaneously opened simultaneously, proceeds to the transition of the no compression shock of first kind of duty again.

Control assembly 10 is to be provided with seal 49 in the zone of dividing plate 47 on its inside and/or outer circumferential surface here.It has prevented the overcurrent between high-pressure side and low-pressure side, and therefore keeps overall system efficiency.According to the physical dimension of this kind equipment, on control assembly 10, also can use a plurality of such seals 49.

Help by means of it places the power transmission shaft 50 of gyration with control assembly 10, supports by supporting member commonly used, and prevents that by means of the seal of knowing liquid from overflowing.Transmission between power transmission shaft 50 and control assembly 10 realizes by the driving member of knowing 51.It can be support bar, dish or other other device, and it makes from low-pressure cavity 45 to interface 46 fluid by becoming possibility.Fig. 3 a that is introduced in of power realizes at the end face of control assembly 10 in the example shown in the 4b.
