[0026] According to a second aspect of the present application, there is provided an electromagnetic floating quantum locking commutation valve, characterized in that it comprises
[0027] The water intake department, including multiple water intake rooms;
[0028] A water outlet portion, comprising a plurality of water outlet chambers;
[0029] A commutation part, the commutation part is arranged between the water inlet and the water outlet, and the commutation part comprises the electromagnetic floating quantum locking commutation structure according to any one of claims 1 to 11;

The water outlets of the 8 water outlet chambers are also arranged in four rows vertically. The 4 water outlets on the left and right sides are connected to the downstream water outlet pipe as water pumping gates, and the 4 water outlets in the two middle rows are connected to the downstream drainage pipe as drainage gates. The water inlets of the 8 water outlet chambers 310 correspond to the 16 flow channels arranged in 4 rows respectively.

[0034] The beneficial effects produced by this application are as follows.
[0035] The arrangement of the flow passage of the present application is combined with the sliding compound valve composed of a sub-gate and a flow ring, which can realize the self-balancing (anti-balancing) of the static water hammer pressure of the sliding compound valve, and the resultant force of the sliding compound valve is 0, and the resultant moment is 0. At the same time, the structure of the flow conversion compound valve also creates a sealing position condition for the isolation of water lifting and drainage and the sealing of pressure internal water. The sealing technology directly controls the pressure seepage leakage, which will improve the water lifting efficiency of the system.
[0036] During the commutation period, an electric motor water pump is used to assist in water lifting and commutation. By first commutating and then water hammering, a commutation water hammer is obtained in which the internal flow does not generate excess pressure and excess flow rate, thereby protecting the pipeline and preventing overpressure, achieving the goal of stable and long-term operation of the entire commutation valve, PCCP pressure pipeline, and water hammer water lifting system, and obtaining a longer working life. Of course, in addition to improving the performance of the commutation reversing valve itself, the commutation reversing valve is equipped with a motor water pump that assists in water lifting and conversion by sensing the outlet water pressure (0.1% accuracy) of the commutation reversing valve or sensing the pressure difference between the commutation outlet and the drainage outlet (and setting the internal flow of the commutation reversing valve at the commutation reversing valve outlet and the internal flow of the drainage outlet to the same pressure target). At the same time, the energy-saving type II symmetrical water hammer technology is adopted (that is, the pipeline technology in which the larger pressure water hammer wave of water lifting and speed reduction is faster than the smaller pressure water hammer wave of drainage speed increase, so that the drainage speed-up pressure recovery reflected wave reaches the commutation reversing valve only after the commutation, creating a commutation window period in which the drainage flow of the commutation reversing valve does not increase in pressure, achieving the effect of stable drainage flow rate, and no drainage due to the high-speed reflection peak of the pressure recovery, and no water energy loss). The quantum electromagnetic coupling locking energy of the commutation reversing valve of the present application only needs to overcome the extremely low load condition (for example, the water pressure difference below 1 meter of water column) to (easily) glide commutation.
[0037] The sliding gate type two-dimensional symmetrical combined commutation reversing valve with strictly controlled water hammer pressure of the present application has the characteristics of self-balancing of the static pressure; the reversing valve creates the working conditions of electromagnetic floating and quantum locking for the commutation reversing valve load; the reversing valve load is structural self-balancing, electromagnetic floating, quantum locking and mechanical wheel-rail redundant multi-field coupling bearing, and the reversing valve load under normal working conditions is electromagnetic floating quantum locking; in each commutation period, the shuttle operation of the reversing valve is non-mechanical bearing, so there is no mechanical friction, thereby ensuring long-term operation; the symmetrical 4-valve commutation of the reversing valve has symmetrical impact on the whole valve, and minimizes the impact on the basic structure outside the valve. The self-balancing of the static pressure of water hammer of the sliding reversing gate structure greatly shares, reduces and even completely relieves the load of the electromagnetic floating quantum locking commutation gate that overcomes the water hammer load, saves electricity, and facilitates the linear motor drive to slide according to the rhythm of water hammer; especially in each water hammer water lifting period, the reversing gate structure self-balancing bears the static pressure of water hammer, which can reduce the quantum locking output and even relieve the electromagnetic floating output force, realizing the minimization of the quantum electromagnetic locking load.

[0063] The present application provides a commutation valve structure using electromagnetic suspension and high-temperature superconducting magnetic levitation coupling locking (electromagnetic quantum coupling locking) technology, which is mainly used in long-distance dual PCCP water hammer water pumping systems. Among them, the electromagnetic suspension and high-temperature superconducting magnetic levitation coupling locking (electromagnetic quantum coupling locking) technology can be understood as follows: electromagnetic suspension actually relies on high-frequency and high-precision sensing of the distance between the rail and the electromagnet pole plate, and the power electronic control equipment (magnetic levitation controller) controls and adjusts the electromagnet excitation current to dynamically stabilize the air gap distance between the rail and the pole plate. High-temperature superconducting magnetic levitation refers to the use of the interaction between high-temperature superconductors and permanent magnets to achieve stable self-suspension, which has the advantages of high efficiency and stable and reliable process. Specifically, the commutation reversing valve of the present application mainly adopts a double-sided quantum locking method, combined with an electromagnetic suspension method, to achieve the technical purpose of stable movement and locking of the sliding reversing door in the valve body in the cavity. Specifically, the quantum locking components (Dewar and permanent magnet rail) and the electromagnetic locking components (U-shaped electromagnet and U-shaped rail) are symmetrically arranged on both sides of the sliding reversing door. The two together serve as a door position locking component. The commutation sliding reversing door of the commutation reversing valve can be strictly locked in the central door position of the internal water flow upward. The commutation of the sliding reversing door during the half-cycle weaving motion of the water hammer does not mechanically bear the main load and does not generate mechanical friction, which is conducive to long-term operation. It also provides technical guarantee for its gate-type or sealed pressure internal hydrodynamic sealing, which is conducive to improving efficiency.
[0064] The present application arranges quantum locking components on the front and rear sides (i.e., both sides) of the sliding compound door, which can achieve (pure) quantum locking without the assistance of sensor feedback control; or by arranging electromagnetic locking components on the front and rear sides (i.e., both sides) of the sliding compound door, and controlling and adjusting the electromagnetic output by sensing the magnetic levitation distance and quantum locking output, the quantum electromagnetic coupling locking enables each sensor feedback control cycle to achieve zero offset correction of the center gate position of the compound valve, that is, the electromagnetic quantum coupling strict locking of the center gate position of the commutation compound valve can be achieved; the electromagnetic locking component and high-frequency sensing can also be used to achieve pure electromagnetic locking of the compound valve. It is worth mentioning that the quantum and electromagnetic coupling locking compound valve is a stable control system that can strictly lock with an accuracy of ±0.01mm, and the stability of locking the center gate position is better than pure electromagnetic floating.
[0065] The linear motor drives the built-in sliding gate to do shuttle reciprocating motion according to the water hammer half-cycle. At the same time, with the specially designed static self-balancing commutation valve body structure and the flow channel design, it can realize the switching of double-pipe water supply to the downstream water lifting and drainage process. The operation process is easy to control. Due to the large flow rate in the water hammer water lifting process, the impact and influence on the valve body are also large. The above design can reduce the impact on the valve body, the anchor pier and the pipeline, and control the leakage to improve the utilization rate of water energy, realize the static water hammer pressure self-balancing (counterbalancing) of the combined sliding gate, and improve the safety and stability of the system; the quantum electromagnetic coupling locking has the ability to overcome the 32-meter water pressure commutation, so when matched with the corresponding PCCP pressure pipeline, it has the ability to lift water with a higher water lift of 32 meters.
[0066] The present application provides a commutation structure and a commutation re-valve using quantum locking and auxiliary electromagnetic locking.
[0067] like Figure 1 In the illustrated embodiment, the commutation structure at least includes a sliding cavity 110 , a sliding door 120 , a quantum locking assembly 130 , a linear motor 140 and an electromagnetic locking assembly 150 .
[0068] The sliding cavity 110 includes a plurality of groups of flow channel components 111 for forming a plurality of flow channels. Each group of flow channel components 111 has gaps in the cross-sectional direction, and the plurality of gaps are interconnected in the same plane.
[0069] The sliding double door 120 is disposed in the gap of the flow channel assembly 111 , and includes a plurality of sub-doors 121 and a flow ring 122 , wherein the plurality of sub-doors 121 and the plurality of flow rings 122 are arranged alternately and spaced apart.
[0070] The quantum locking component 130 includes a dewar 131 and a permanent magnet track 132 arranged correspondingly in the front-to-back direction. A group of dewar groups are respectively arranged at the upper edge and the lower edge of the flow channel component 111. Each group of the dewar groups includes two dewars 131 arranged at the front and rear sides of the gap. The upper edge and the lower edge of the sub-gate 121 and the flow ring 122 are respectively provided with a permanent magnet track 132. The permanent magnet track 132 is located between the two correspondingly arranged dewars 131. It can be understood that the permanent magnet track 132 is a double-sided permanent magnet track to form a symmetrical and stable quantum locking relationship with the two dewars 131 arranged correspondingly in the front-to-back direction.
[0071] The linear motor 140 is connected to the sliding cavity 110 and the sliding door 120 , so the linear motor 140 , as a shuttle driving component, can drive the sliding door 120 to perform reciprocating shuttle motion in the sliding cavity 110 .
[0072] A part of the sub-gates 121 can block the passage of a part of the flow channel during the reciprocating motion, and a part of the flow ring 122 overlaps with another part of the flow channel during the reciprocating motion and makes it pass through. The reciprocating motion process of the sliding gate 120 makes different flow channels alternately pass through, thereby realizing the switching of water lifting and drainage.
[0073] The gaps of all the flow channel components 111 are connected in the same cross-sectional plane, so that the sliding compound door can realize sliding motion in the sliding cavity.

This shape not only thickens the wall thickness of the channel component and can withstand greater water flow impact, but also provides a storage position for the permanent magnet rails arranged on its upper and lower edges, which will be explained in more detail below.
[0076] According to other embodiments of the present application, the outer wall shape of the flow channel assembly 111 can also be selectively constructed into a circular, rectangular, square or other polygonal shapes according to different requirements.
[0077] It should be noted that the shapes of the outer wall and inner wall of the above-mentioned flow channel component 111 refer to the shapes of the outer edge and inner edge of the flow channel component in the cross-sectional direction.
[0078] According to a preferred embodiment of the present application, the sliding cavity 110 includes 16 flow passages, such as Figure 3 In the embodiment shown, the 16 flow passages can be arranged into two first flow longitudinal columns 1101 and two second flow longitudinal columns 1102, wherein the first flow longitudinal columns 1101 and the second flow longitudinal columns 1102 each include four longitudinally arranged flow passages, the two second flow longitudinal columns 1102 are arranged between the two first flow longitudinal columns 1101, an intermediate vacant column 1103 is arranged between the two second flow longitudinal columns 1102, and an vacant column is respectively arranged on the relatively outer sides of the two first flow longitudinal columns 1101.
[0079] The first flow column 1101 and the second flow column 1102 may correspond to a water pumping function and a water discharge function, or correspond to a water discharge function and a water pumping function, respectively.
[0080] According to one embodiment of the present application, the sliding compound door 120 adopts a compound door structure, wherein the sliding compound door 120 includes a plurality of sub-doors 121 and a flow ring 122, and the spacing arrangement thereof matches the arrangement of the flow channel.
[0081] According to a preferred embodiment of the present application, the sliding compound door 120 includes 12 sub-doors 121 and 12 current rings 122. Figure 4 In the embodiment shown, the sub-gates 121 and flow rings 122 of the sliding compound gate 120 are arranged in 4 horizontal rows, and the sub-gates 121 and flow rings 122 in each horizontal row are arranged in an interlaced manner, wherein the top horizontal row and the bottom horizontal row are the first horizontal rows 1201 arranged in the same manner, and between the two first horizontal rows 1201 are the two second horizontal rows 1202 arranged in the same manner, and the sub-gates 121 and flow rings 122 in the first horizontal row 1201 and the sub-gates 121 and flow rings 122 in the second horizontal row 1202 are arranged in an interlaced manner. The flow ring 122 is an annular structure corresponding to the annular columnar structure of the flow channel assembly 111, and its vertical height is not greater than the height of the sub-gate 121. For specific reference Figure 4In the embodiment shown, the sub-gates 121 and the flow rings 122 are arranged in sequence from left to right in the first horizontal row 1201 at the top, and the arrangement manner is an interval arrangement. In the second horizontal row 1202 below the first horizontal row 1201 at the top, the flow rings 122 and the sub-gates 121 are arranged in sequence from left to right, and the arrangement manner is also an interval arrangement. Since the arrangement order of the sub-gates and flow rings in the first horizontal row 1201 and the second horizontal row 1202 is different, they are arranged in a staggered manner from top to bottom. This method can realize reasonable switching between the flow channels with water lifting / drainage functions during sliding.
[0082] Preferably, the cross section of the flow ring 122 is selected to have the same shape as the inner wall shape of the flow channel, and in particular, the inner wall shape of the flow ring 122 is exactly the same as the inner shape of the flow channel, so that the flow ring 122 is completely aligned with the flow channel so that water can pass through unimpeded, and the impact on the flow ring can also be avoided. The outer wall shape of the flow ring 122 can be selected according to actual engineering requirements.
[0083] According to a preferred embodiment of the present application, the inner wall shape of the flow ring 122 is configured to be an ellipse that is completely identical to the inner wall of the flow channel.
[0084] A crossbeam 123 is provided on the upper and lower sides of each horizontal row of the sliding compound door 120, and longitudinal spokes 124 are provided at least between the middle adjacent sub-doors and the flow ring and on the left and right sides of the sliding compound door. The crossbeam 123 and the longitudinal spokes 124 form an overall frame structure connecting the sub-doors and the flow ring.
[0085] The cross beam 123 can be constructed as a plate-like structure with a suitable thickness, and the sub-doors and the flow rings are connected to the cross beam and fixed between adjacent cross beams, so that the sub-doors 121 and the flow rings 122 are connected and fixed to each other, thereby forming the overall structure of the sliding compound door. According to the structure shown in the illustrated embodiment, the multiple cross beams 123 are evenly distributed, and the extension of the cross beams 123 is along the lateral direction and the front-back direction.
[0086] In some embodiments, the cross beam 123 may be a hollow structure, which is beneficial for water to flow through the sliding cavity when the sliding door slides.
[0087] According to a preferred embodiment of the present application, the sliding door 120 includes five cross beams 123, as shown in FIG. Figure 4 As shown, three of the cross beams 123 are used as middle beams 1233 and are respectively sandwiched between the two first horizontal rows 1201 and the two second horizontal rows 1202, and the remaining two cross beams 123 are used as top beams 1231 and bottom beams 1232 and are respectively arranged at the top of the upper first horizontal row 1201 and the bottom of the lower second horizontal row 1202, that is, as the outer frames of the top and bottom of the sliding door.
[0088] According to an embodiment of the present application, the crossbeam 123 may be constructed as a fused rail structure, and the specific structure will be described in detail below.
[0089] As an optional embodiment, the longitudinal spokes 124 located in the middle position can be arranged in only one horizontal row, or can run through at least two horizontal rows as needed. The longitudinal spokes 124 can increase the overall strength of the sliding compound door, ensure the precision of fine machining and micron fine machining of the compound door surface during production, and ensure the airtight and water-stopping effect of the end face sealing.
[0090] According to one embodiment of the present application, the dewar 131 is arranged on the upper edge and the lower edge of the flow channel assembly 111. Based on the gap, the flow channel assembly 111 is divided into two parts, front and rear, and the upper side walls of the front and rear flow channel assemblies are correspondingly provided with a group of dewar groups, that is, the two dewars 131 in the group of dewar groups are respectively embedded in the upper side walls of the flow channel assembly 111 in front and behind the gap. Similarly, the lower side walls of the front and rear flow channel assemblies are also correspondingly provided with a group of dewar groups, that is, the two dewars 131 in the group of dewar groups are respectively embedded in the lower side walls of the flow channel assembly 111 in front and behind the gap, and the two dewars 131 of each group of dewars are arranged in front and back alignment based on the central cross-sectional direction of the sliding compound door.
[0091] It can be understood that during the sliding and locking process of the quantum locking assembly, there is no contact and friction between the dewar 131 and the permanent magnet rail 132, so there needs to be a gap between the dewar 131 and the permanent magnet rail 132. In this embodiment, the gap between the permanent magnet rail 132 and the dewar 131 on one side is 5 mm ± 2 mm, and the gap between the permanent magnet rail 132 and the dewar 131 on the other side is 2 mm. That is, the sum of the two gaps between the permanent magnet rail 132 and the dewars 131 on both sides is 10 mm.
[0092] like Figure 2 In the embodiment shown, since the flow passage assembly 111 is constructed as an annular columnar structure with a circular outer wall and an elliptical inner wall, and the major axis of the elliptical inner wall is parallel to the horizontal direction, the wall of the flow passage assembly 111 in the upper and lower directions is relatively thick, and is obviously thicker than the wall thickness in the left and right directions. Mounting grooves are preset at the thicker wall positions in the upper and lower directions of the outer wall, and the dewar 131 is embedded in the mounting grooves, so that the upper and lower walls of the flow passage assembly 111 are both embedded with the dewar 131, and the flow passage is located between the two dewars 131 in the upper and lower directions.
[0093] According to an embodiment of the present application, the permanent magnetic track 132 is disposed on the sliding door 120. Figure 4 , Figure 5AIn the embodiment shown, the transversely extending permanent magnet rail 132 is arranged on the upper and lower sides of the same horizontal sub-gate 121 and the current ring 122. When the sliding compound door 120 is installed in the gap of the sliding cavity 110, the position of the permanent magnet rail 132 is located between the front and rear two dewars 131 of the corresponding group of dewars. It can be understood that the front and rear surfaces of the permanent magnet rail 132 maintain a micro distance from the corresponding dewar 131 to meet the requirements of relative sliding.
[0094] Optionally, the upper edge, lower edge, left edge and right edge of the flow ring 122 can be connected to the permanent magnet track 132, the sub-gate 121 and the longitudinal spoke 124 directly or through a connecting element 1221. The permanent magnet track 132 and the sub-gate 121 and the longitudinal spoke 124 can also be connected directly or through a suitable connecting element. It can be understood that according to the actual application of the valve body, radial spokes (not shown in the figure) can be added inside the ring, extending from the geometric center of the ellipse to the flow ring 122, and then continuing to extend to the connection position of the longitudinal spoke and / or the sub-gate, so as to further ensure the rigidity of the flow ring.
[0095] The transverse permanent magnet rail 132 can be the same length as the crossbeam 123 of the sliding double door, and the entire permanent magnet rail 132 can be in an integrated form. A transverse integral permanent magnet rail 132 can also be formed by splicing 6 short sections of permanent magnet rails with a length equal to the width of the first / second current-carrying longitudinal columns, which is more convenient for transportation and maintenance.
[0096] Preferably, the permanent magnet rail 132 adopts a Halbach permanent magnet rail. An additional protective plate can be provided in the sliding compound door, and the permanent magnet rail section and the sub-door can be installed inside the protective plate. In other words, the protective plate can be constructed as a thin plate of the same shape that just covers the front and rear sides of the permanent magnet rail and the sub-door, thereby making the installation of the permanent magnet rail and the sub-door more stable and also playing a protective role. Alternatively, the protective plate is a structure formed integrally with the sub-door, which extends upward and downward from the front and rear edge positions of the sub-door to the crossbeam position, and there is an accommodation space for accommodating the permanent magnet rail between the front and rear protection plates (not shown in the figure), thereby also achieving the installation and protection of the permanent magnet rail 132.
[0097] According to the structural design of the above-mentioned quantum locking component 130, it can be known that due to the physical properties between the dewar and the permanent magnet, that is, the high-temperature superconductor can strictly quantum lock the permanent magnet in a constant low temperature environment, so with the help of the above-mentioned physical properties, the permanent magnet rail 132 can be stably moved and locked between the dewar 131, thereby realizing the operation process of the sliding door stably performing horizontal reciprocating motion in the sliding cavity and locking at the desired position.
[0098] The dewar 131 can adopt the existing dewar arrangement, wherein superconductors are uniformly arranged inside, such as YBaCuO high temperature superconductor blocks, etc., and the permanent magnet rail 132 can adopt NdFeB permanent magnet rails, etc. Dewar and permanent magnets are already in actual use in the field of maglev trains, so the selection of dewar and permanent magnets can be selected according to the technical knowledge of technicians in this field and actual engineering needs, and no additional restrictions are made here.
[0099] According to an embodiment of the present application, a linear motor 140 is additionally configured in the slide chamber 110, and the linear motor 140 is arranged in the space between the top and / or bottom of the slide door 120 and the inner wall of the slide chamber. It can be understood that the linear motor can be connected to the top and / or bottom of the slide door 120, respectively, and can drive the slide door 120 to perform reciprocating linear motion in the slide chamber 110 according to the rhythm of water hammer. The installation structure of the linear motor can be reasonably arranged according to the conventional technical knowledge of those skilled in the art in the figure, so it is not described in detail.
[0100] According to a preferred embodiment of the present application, the linear motor 140 is arranged in the space between the upper surface of the top beam 1231 of the sliding compound door 120 and the inner wall of the sliding cavity, and in the space between the lower surface of the bottom beam 1232 of the sliding compound door 120 and the inner wall of the sliding cavity. The upper and lower linear motors are respectively connected to the top beam 1231 and the bottom beam 1232, so as to drive the sliding compound door 120 to perform reciprocating linear motion in the sliding cavity 110 according to the rhythm of water hammer.
[0101] You can Figure 1 As shown, the movers of the linear motors are arranged on the upper surface of the top beam 1231 and the lower surface of the bottom beam 1232 corresponding to the positions of the first current-passing longitudinal column 1101 and the second current-passing longitudinal column 1102, respectively. In this way, the driving force given to the sliding compound door is overall balanced, so as to stably drive the movement of the sliding compound door and balance the force on the sliding compound door from the perspective of the motor driving force.
[0102] According to one embodiment of the present application, an electromagnetic locking assembly 150 is further configured in the commutation structure, and the rail 153 of the electromagnetic locking assembly 150 is made integrally with the crossbeam 123 in a manner of fusing the rail. Figure 5BAs shown in the dotted position in . The rail 153 forms a U-shaped track on the front and rear end faces of the crossbeam 123, respectively, and its notch faces the front / rear direction. The inner wall of the sliding cavity 110 is preset with a groove, and the electromagnet 152 of the electromagnetic locking assembly 150 is built into the groove. The electromagnet 152 is arranged in a manner that an iron core 1522 is sandwiched between the upper and lower pole plates 1521 and a coil (not shown in the figure) is surrounded by the iron core. The positions of the upper and lower pole plates 1521 correspond to the upper and lower edges of the notch of the U-shaped track, respectively, and the spacing between the upper and lower pole plates 1521 can be equal to the notch height of the U-shaped track. A gap of 5mm±2mm is left between the pole plate 1521 of the electromagnet 152 and the rail 153. Preferably, maintaining a 5mm spacing is optimal for relative sliding behavior.
[0103] During operation, the upper and lower edges of the slot of the U-shaped track work in pairs with the fixed electromagnet pole plates, that is, relative movement occurs through electromagnetic induction. During the movement, the rail and the electromagnet do not contact or frictionally extend. The electromagnet 152 can extend laterally to be equal to the lateral length of the inner wall of the sliding cavity, or slightly smaller than the lateral length of the inner wall of the sliding cavity, as long as it can achieve electromagnetic induction with the rail 153 and thereby ensure the function of offset correction of the electromagnetic induction component.
[0104] More preferably, Figure 4 , Figure 5A and Figure 5B As shown, a fixed rail 151 is provided in the notch of the U-shaped track, which is a non-magnetic slide rail, that is, it is made of non-magnetic materials, such as non-metallic materials, non-magnetic steel, etc. The fixed rail 151 is attached to the bottom of the U-shaped rail groove and works in pairs, coupling to share the electromagnetic load overload, and completely bearing the main load when the electromagnetic fails. When the fixed rail 151 uses a sliding guide rail, there is sliding friction, and when the fixed rail 151 uses a rolling guide rail, there is rolling friction. More preferably, a lubricating guide shoe 1511, a roller (roller or needle roller) or a slide rail sleeve can be embedded in the side of the fixed rail 151 facing the bottom of the U-shaped groove. The guide shoe can be a guide shoe with a low friction coefficient made of synthetic materials such as copper-inlaid graphite, copper-carbon powder alloy, ironwood, water-lubricated rubber, etc., thereby obtaining lubrication and low-friction sliding.
[0105] It is necessary that the positions of the electromagnet 152 and the rail 153 are arranged corresponding to each other. Specifically, the number of grooves arranged on the front inner wall and the rear inner wall of the sliding cavity 110 is the same as the number of the cross beams 123, and the spacing between adjacent grooves is equal to the spacing of the cross beams. Therefore, the electromagnet 132 built into the groove can correspond to multiple rails 153 one by one, which is conducive to assisting in correcting the offset of the relative position of the sliding compound door 120 and the sliding cavity 110, and can withstand stronger water flow impact. As shown in the figure, the shell 112 is the inner wall of the sliding cavity 110. During the manufacturing process, the pole plate 1521 can be made integrally therewith, so that the electric iron core and the excitation coil can be placed in the protective space of the isolation wall outside the sliding cavity because they are separable from the pole plate 1521, which is conducive to insulation protection.
[0106] In the present application, the electromagnetic locking assembly 150 is used as an auxiliary stable active control system, which is used for the correction of offset. Specifically, the offset of the sub-gate unit is obtained by sensing, and according to the offset, it can be known how much the quantum force is generated due to the offset, which is greater than the quantum locking force without offset, and then fed back to the electromagnet 152 and the electromagnet 152 increments this force, and the quantum output can return to the quantum output without offset, thereby realizing the zero offset correction of the gate position within the sensing cycle. In other words, when the locking capacity of the self-stabilizing quantum locking assembly 130 is insufficient to strictly lock the gate position of the sliding compound door 120, that is, when the sliding compound door is slightly offset laterally due to the impact of water flow, the electromagnetic locking assembly 150 can further actively control and adjust the electromagnetic force to make the sliding compound door resist this deflection force, and correct the zero offset, and the electromagnet gives the auxiliary locking force that exceeds the quantum locking capacity. High frequency continuous adjustment, and realize the self-locking of quantum physical characteristics of the whole process of commutation sliding and the coupling of electromagnetic active sensing feedback locking to strictly lock the commutation gate position. Similar to the maglev train, the quantum lock and electromagnetic levitation lock also have guiding forces to overcome the disturbance of the plumb direction of the sliding door (such as gravity) to prevent the up and down deviation movement. Like the main load in the horizontal direction, the slide rail is also coupled with the electromagnet in the plumb direction. The slide rail can bear no or little mechanical load under low disturbance load conditions.
[0107] As a preferred embodiment, the electromagnet 152 and the rail 153 are arranged at the front and rear of the sliding door 120, and the arrangement is symmetrical based on the sliding door 120. Figure 1 and Figure 3As shown, a total of five beams 123 are arranged on the upper and lower sides of the two first horizontal rows 1201 and the two second horizontal rows 1202 of the sliding compound door. Since the front and rear end surfaces of the beams 123 are symmetrical, the rails 153 integrated into the front and rear end surfaces of the beams 123 are also symmetrical, and the electromagnets 132 corresponding to the rails 153 are also front-to-back symmetrical relative to the sliding compound door 120. Therefore, the electromagnetic locking assembly 150 is overall front-to-back symmetrical relative to the sliding compound door, and can realize a bilaterally symmetrical electromagnetic locking function, thereby ensuring the stability of locking and the accuracy of offset correction.
[0108] It can be understood that the cross-sectional (end face) shape and size of the flow ring 122 match the cross-sectional (end face) shape and size of the inner wall of the flow channel assembly 111, and the cross-sectional shape of the sub-gate 121 is a square whose side length is greater than the major axis size of the elliptical cross-sectional shape of the flow channel assembly 111, or a rectangle whose minimum side size is greater than the major axis size of the elliptical cross-sectional shape of the flow channel assembly 111. Based on this structure, when the sliding compound door 120 moves to the through position, the flow ring 122 and the corresponding end face of the flow channel assembly 111 can just overlap, and cooperate with the end face sealing body to ensure the water flow and sealing to the greatest extent, so as to realize the "opening" of the channel. At the same time, the sub-gate can completely block the corresponding end face of the flow channel assembly, thereby blocking the water flow of the flow channel and realizing the "closing" of the channel.
[0109] In the above embodiment, the flow passage integrates the end face seal and radial cylindrical seal in the shape of a hollow bottom piston or an aircraft engine casing. The end face seal structure can use a graphite ring end face seal or an end face copper-carbon powder metallurgy self-lubricating seal. The radial seal can use a self-lubricating metal material piston ring seal, an Igus sliding bearing polymer self-lubricating composite material piston expansion ring, and a rolling polymer O-ring, and is set at the end of the flow port sliding door. The seal body can be 3D printed like the casing, and the parallel end face seal can add a wide edge to resist stress deformation, and a cylindrical seal is arranged between the two wide edges. The end face sealing structure is used to fit closely to the sub-gate and the flow ring surface and can flexibly deviate from the balance center within ±5mm in the upstream and downstream (the rear and front directions in this application). In addition, the end face of the flow channel assembly 111 can be constructed with a top chamfer to facilitate sliding fit with the sub-gate and the flow ring surface. The cylinder body adopts lightweight metal alloy or Igus sliding bearing material so that it can better fit the inner wall of the flow channel opening, and electromagnetic control cooperates with the complex valve switching sliding and the end face sealing to perform micro-axial sliding to achieve the sealing of the radial cylindrical sliding surface gap, and the end face sealing relies on the graphite ring end face to fit the sub-gate and the flow ring, thereby reducing the friction coefficient, thereby reducing maintenance work, improving corrosion resistance, and extending service life.
[0110] According to one embodiment of the present application, Figure 6As shown, the slide chamber 110 further includes a housing 112, which serves as a shell for enclosing the slide chamber 110. The slide gate 120, the flow channel assembly 111, the dewar 131, the electromagnet 152, and the linear motor 140 are accommodated in the housing 112 to achieve the sealing of the commutation structure. Since the flow channel needs to be through the front-to-back direction to allow water to pass through, the end of the flow channel assembly 111 is formed as a through hole on the housing 112.
[0111] The present application does not impose any particular limitation on the specific shape of the housing 112, as long as the installation and operation of the sliding door, electromagnetic induction assembly, motor and other components inside the housing 112 can be achieved.
[0112] The present application also provides a commutation valve with a commutation structure using the electromagnetic floating quantum coupling locking technology. The commutation valve includes a water inlet 200, a water outlet 300 and a commutation part 100. Figure 6 In the illustrated embodiment, the flow conversion unit 100 is disposed between the water inlet 200 and the water outlet 300 , and the flow conversion unit 100 includes the flow conversion structure as described above.
[0113] According to one embodiment of the present application, the water inlet part 200 includes a plurality of water inlet rooms 210, each of the water inlet rooms 210 includes a water inlet and two transversely arranged water outlets, and the two transversely arranged water outlets are respectively connected to each of the flow channels in the adjacent first flow column 1101 and the second flow column 1102 in the sliding cavity of the flow conversion structure.
[0114] According to one embodiment of the present application, the water outlet part 300 includes a plurality of water outlet chambers 310, each of the water outlet chambers 310 includes a water outlet and two longitudinally arranged water inlets, and the two longitudinally arranged water inlets are connected to two adjacent flow channels in a vertical column in the sliding cavity of the flow conversion structure.
[0115] The reversing re-valve of the present application is applied to a water delivery and drainage system of double PCCP pipes, which includes a first PCCP pipe and a second PCCP pipe upstream, a downstream water lifting pipe and a downstream drainage pipe downstream. The water outlet ends of the first PCCP pipe and the second PCCP pipe are connected to the water inlet 200 of the reversing re-valve, and the water inlet ends of the downstream water lifting pipe and the downstream drainage pipe are connected to the water outlet 300 of the reversing re-valve.
[0116] According to the above embodiment of the present application, half of the water inlets in the water inlet part 200 of the reversing valve are connected to the first PCCP pipe, and the other half of the water inlets are connected to the second PCCP pipe. Specifically, the first PCCP pipe can be connected to the water inlets at the top and bottom arranged at intervals, and the second PCCP pipe is connected to the two rows of water inlets in the middle part.
[0117] Similarly, half of the water outlets in the water outlet portion 300 of the reversing valve are connected to the downstream water lifting pipe, and the other half of the water outlets are connected to the downstream drainage pipe. Specifically, the downstream water lifting pipe can be connected to the leftmost and rightmost water outlets arranged at intervals, and the downstream drainage pipe can be connected to the two columns of water outlets in the middle part. Of course, the opposite arrangement can also be made, in which the downstream drainage pipe is connected to the leftmost and rightmost water outlets arranged at intervals, and the downstream water lifting pipe is connected to the two columns of water inlets in the middle part. The above connection method can be specifically designed according to the actual environment and the upstream and downstream piping method.
[0118] According to a preferred embodiment of the present application, Figures 6 to 10 As shown, the water inlet 200 includes 8 water inlet rooms 210, and the 8 water inlet rooms 210 are arranged in four rows horizontally. Accordingly, the water inlets of the 8 water inlet rooms 210 are also arranged in four rows horizontally. The water outlets of the 8 water inlet rooms 210 correspond to the 16 flow channels arranged in the four columns. In this embodiment, the four first water inlets 2111 in the two rows at the top and bottom are connected to the first PCCP pipe, and the four second water inlets 2112 in the two middle rows are connected to the second PCCP pipe.
[0119] According to a preferred embodiment of the present application, Figure 6 , Figure 7 , Figures 11 to 13 As shown, the water outlet portion 300 includes 8 water outlet chambers 310, and the 8 water outlet chambers 310 are arranged in four rows longitudinally. Accordingly, the water outlets of the 8 water outlet chambers 310 are also arranged in four rows longitudinally. The water inlets of the 8 water outlet chambers 310 correspond to the 16 flow passages arranged in the four rows. In this embodiment, the four water outlets in the two rows on the left and right sides are connected to the downstream water supply pipe as water supply ports 3121, and the four water outlets in the two middle rows are connected to the downstream drainage pipe as drainage ports 3122. Of course, the opposite connection can also be made.
[0120] It is understandable that, for a single water inlet chamber 210, the longitudinal cross section of the water inlet chamber 210 gradually increases from the water inlet to the water outlet; for a single water outlet chamber 310, the longitudinal cross section of the water outlet chamber gradually decreases from the water inlet to the water outlet. For the whole flow-converting valve, the cross-sectional area of the chamber in the front-to-back direction gradually changes, which is conducive to the automatic adjustment of the internal flow field and the maintenance of the micro-momentum balance, and has a certain water flow buffering function and a reasonable layout of the overall external structure.
[0121] For the 16 flow channels, the sliding compound door can group them to achieve partial penetration and partial non-penetration (blocked by the quilt door) at a certain door position. For the sake of convenience, multiple flow channels that are simultaneously penetrated / non-penetrated at a certain door position are defined as M group and N group. In combination with the principle, structure and drawings of the present application, it can be understood that: when the door position is locked in the first phase, the flow channels of the M group are penetrated from front to back, and the flow channels of the N group are non-penetrating (blocked); when the door position is locked in the second phase, the flow channels of the M group are non-penetrating (blocked), and the flow channels of the N group are penetrated from front to back. Accordingly, at different door positions, the penetration / non-penetration status of the M group and the N group is alternated according to the reciprocating motion of the sliding compound door, thereby realizing the switching of different water flow directions inwardly of the valve body.
[0122] In the prior art, for a PCCP water delivery system with extremely large water flow, the pressure on each flow port and the switching process is huge, and the valve body is easily damaged or even damaged due to overpressure. The flow conversion re-valve protected by the present application, in principle, adopts a re-valve flow conversion valve with four single valves arranged in a strict two-dimensional symmetry (center symmetry) according to the flow ports 2×2, wherein each flow conversion single valve includes two water inlet chambers, two water outlet chambers, a sliding door and its corresponding sliding cavity. From the overall point of view, it can be understood that the re-valve is composed of four single valves, including eight water inlet chambers, eight water outlet chambers, and a sliding re-valve composed of four sliding doors and an overall sliding cavity formed by the fusion of the sliding re-valve and its four sliding cavities. Corresponding to the actual use process, for the single valve, the water inlet is divided into left and right water inlet, the water lifting is arranged on the upper layer, and the drainage is arranged on the lower layer. Correspondingly, due to the two-dimensional symmetry (center symmetry) of the corresponding four single valves in the re-valve flow conversion valve, the arrangement of water inlet, water lifting and drainage also presents two-dimensional symmetry (center symmetry).
[0123] During the commutation period, the motor water pump assists in water lifting and commutation. By commutating first and then water hammering, a commutation water hammer without excessive pressure and excessive flow rate is obtained, thereby protecting the pipeline and preventing overpressure, achieving the purpose of stable and long-term operation of the entire commutation valve, PCCP pressure pipeline and water hammer water lifting system, and obtaining a longer working life. Of course, in addition to improving the performance of the converter valve itself, it is also coordinated with the use of a motor pump that controls the water outlet pressure (0.1% accuracy) of the converter valve or the pressure difference between the water outlet and the drainage outlet (and the goal of isolating the internal flow of the converter valve water outlet and the internal flow of the drainage outlet) to assist in water lifting and conversion measures. At the same time, energy-saving type II symmetrical water hammer technology is also adopted (that is, the pipeline technology in which the larger pressure water hammer wave of water lifting and speed reduction is faster than the smaller pressure water hammer wave of drainage speed increase, so that the drainage speed-up pressure recovery reflected wave reaches the converter valve only after the conversion, creating a conversion window period in which the converter valve drainage overcurrent does not increase the pressure, achieving a stable drainage flow rate, and the effect of no loss of high-speed water energy due to pressure recovery), so that the quantum electromagnetic coupling locking of the converter valve of the present application only needs to overcome extremely low load conditions (for example, water pressure difference below 1 meter water column) to easily glide and convert.
[0124] The sliding gate type two-dimensional symmetrical combined commutation valve with strictly controlled water hammer pressure of the present application has the characteristic of self-balancing of the static pressure it is subjected to. The valve creates the working conditions of electromagnetic floating and quantum locking for the commutation valve load. The valve load is structural self-balancing, electromagnetic floating, quantum locking and mechanical wheel-rail redundant multi-field coupling bearing, and the valve load under normal working conditions is electromagnetic floating quantum locking. In each commutation period, the shuttle operation of the valve is non-mechanical bearing, so there is no mechanical friction, thereby ensuring long-term operation. The self-balancing of the static pressure of water hammer of the sliding gate structure greatly reduces and completely relieves the load of the electromagnetic floating quantum locking commutation gate that overcomes the water hammer load, saves electricity, and facilitates the linear motor drive to slide according to the rhythm of water hammer; especially in each water hammer water lifting period, the gate structure self-balances the water hammer static pressure, which can reduce the quantum locking output and even relieve the electromagnetic floating output force, realizing the minimization of the quantum electromagnetic locking load.
[0125] The arrangement of the flow channel of the present application is combined with the sliding compound valve composed of a sub-gate and a flow ring, which can realize the self-balancing (resistance) of the static water hammer pressure of the sliding compound valve. The resultant force of the sliding compound valve is 0, and the resultant moment is 0. In addition, when the cross-section of the flow channel and the flow ring is circular, elliptical, rectangular, or square, the static water pressure of the sliding compound valve during the sliding process can also be completely self-balanced. At the same time, the structure of the flow conversion valve also creates a sealed working position condition for water lifting and drainage isolation and pressure internal water sealing. The sealing technology directly controls the pressure seepage leakage, which will make the system water lifting efficiency the highest.
[0126] A preferred embodiment of the present application is described in detail below with reference to the accompanying drawings.
[0127] Combination Figure 1The commutation structure of the preferred embodiment shown includes a sliding cavity 110 , a sliding compound door 120 , a quantum locking assembly 130 , a linear motor 140 and an electromagnetic locking assembly 150 .
[0128] In this embodiment, the sliding cavity 110 includes 16 groups of flow channel components 111 for forming 16 flow channels, each group of flow channel components 111 has a gap in the cross-sectional direction, and the gaps of all flow channel components 111 are interconnected in the same plane. The 16 flow channels are arranged in a reasonable manner, combined with Figure 1 and Figure 3 In the arrangement shown, 16 flow passages are arranged into 2 first flow columns 1101 and 2 second flow columns 1102, and 4 flow passages are arranged longitudinally in each of the first flow columns 1101 and the second flow columns 1102. The two second flow columns 1102 are arranged between the two first flow columns 1101, and an intermediate vacant column 1103 is arranged between the two second flow columns 1102. The first vacant column 1104 and the second vacant column 1105 are arranged on the opposite outer sides of the two first flow columns 1101, respectively.
[0129] The flow channel assembly 111 is constructed as an annular columnar structure, and has a gap in the cross-sectional direction of the annular columnar structure. That is, the gap separates the flow channel assembly 111 in the annular columnar structure into two parts located at the front and rear sides respectively. The end faces located at the front and rear sides are respectively connected to the outer shell of the sliding cavity and realize the internal penetration of the flow channel.
[0130] The flow passage assembly 111 may be constructed as follows Figures 1 to 3 , Figure 6 The structure shown has a circular outer wall and an elliptical inner wall, and the long axis of the ellipse is arranged parallel to the horizontal direction. Therefore, the walls of the flow channel component 111 in the upper and lower directions are relatively thick, which is obviously thicker than the wall thickness in the left and right directions. Such a shape not only thickens the wall thickness of the channel component to withstand greater water flow impact, but also provides an accommodation position for the Dewar 131 arranged on its upper and lower edges.
[0131] Specifically, mounting grooves are preset at positions where the wall is thicker on the upper and lower sides of the outer wall, and the dewar 131 is embedded in the mounting grooves. Therefore, the upper and lower walls of the flow channel assembly 111 on the front and rear sides of the gap are embedded with the dewar 131, and the flow channel is located between the two dewars 131 in the upper and lower directions, and the two dewars 131 of the upper wall of the flow channel assembly 111 on the front and rear sides of the gap are symmetrically arranged based on the cross-sectional direction. Similarly, the two dewars 131 of the lower wall on the front and rear sides are also symmetrically arranged based on the cross-sectional direction.
[0132] In this embodiment, if Figure 7As shown, the first flow column 1101 and the second flow column 1102 correspond to the water lifting function and the water discharge function respectively.
[0133] In this embodiment, the sliding double door 120 is an integral double door structure, adopts a two-dimensional symmetrical static self-balancing 12 sub-door design, and is accommodated in the gap of the flow channel assembly 111. Figure 4 As shown, the sliding compound door 120 includes 12 sub-doors 121 and 12 flow rings 122, and the 12 sub-doors 121 and 12 flow rings 122 are arranged in a reasonable manner. Figure 1 and Figure 3 As shown, the sub-gates 121 and the current rings 122 of the sliding compound gate 120 are arranged in 4 horizontal rows, each horizontal row includes 3 sub-gates and 3 current rings, and the 3 sub-gates and 3 current rings are arranged alternately. In order to achieve its commutation function, the top horizontal row and the bottom horizontal row are the first horizontal rows 1201 arranged in the same manner, and the two second horizontal rows 1202 arranged in the same manner are between the two first horizontal rows 1201. Figure 4 It can be clearly seen that the first horizontal row 1201 starts with a sub-gate on the left side, and the sub-gates and the flow rings are arranged alternately and sequentially to the right, and the flow rings are stopped on the right side; the second horizontal row 1202 starts with a flow ring on the left side, and the sub-gates and the flow rings are arranged alternately and sequentially to the right, and the sub-gates are stopped on the right side. Therefore, the sub-gates 121 and the flow rings 122 in the first horizontal row 1201 and the sub-gates 121 and the flow rings 122 in the second horizontal row 1202 are arranged alternately up and down, and such a design can realize the reasonable switching between the flow channels with water lifting or drainage functions during the sliding process.
[0134] In this embodiment, the flow ring 122 is constructed as an elliptical ring with the same shape as the inner wall of the flow channel assembly 111, with its transverse major axis parallel to the horizontal direction, its longitudinal minor axis parallel to the vertical direction, and the minor axis length slightly less than the height of the sub-gate 121. Preferably, the flow ring 122 is connected to the upper and lower double-sided permanent magnetic rails 132, the left and right sub-gates 121 or the longitudinal spokes 124 through the connecting element 1221.
[0135] In this embodiment, the sliding compound door 120 further includes five cross beams 123 with fused rails, and the cross beams 123 are components of the frame structure connecting the sub-doors 121 and the flow ring 122. Figure 4As shown, three of the cross beams 123 are used as middle beams 1233 and are respectively sandwiched between the two first horizontal rows 1201 and the two second horizontal rows 1202, so that the sub-doors 121 and the current rings 122 are connected and fixed to each other, and the remaining two cross beams 123 are used as top beams 1231 and bottom beams 1232 and are respectively arranged at the top of the upper first horizontal row 1201 and the bottom of the lower second horizontal row 1202, that is, as the outer frames of the top and bottom of the sliding compound door.
[0136] like Figure 4 and Figure 5A As shown, the double-sided permanent magnet rail 132 is arranged on the sliding compound door 120, and the double-sided permanent magnet rail 132 extending laterally is arranged on the upper and lower sides of the sub-door 121 and the current ring 122 in the same horizontal row. When the sliding compound door 120 is installed in the gap of the sliding cavity 110, the position of the double-sided permanent magnet rail 132 is located between the front and rear two dewars 131 of the corresponding group of dewar groups.
[0137] In this embodiment, the cross beam 123 can be constructed as a hollow plate structure with a certain height, which can meet the rigidity requirements of the load and the requirements of water flow in the sliding cavity. The double-sided permanent magnetic rail 132 is connected to the cross beam 123, and the sub-door 121 and the flow ring 122 are fixed between the two double-sided permanent magnetic rails 132 to form the overall structure of the sliding compound door. Figure 1 and Figure 4 In the structure shown, the plurality of cross beams 123 are evenly distributed, and the cross beams 123 extend along the lateral direction and the front-rear direction.
[0138] In this embodiment, the sliding compound door 120 is further provided with three evenly distributed longitudinal spokes 124, which are also components of the frame structure, wherein one longitudinal spoke 124 is provided at the leftmost and rightmost sides, and another longitudinal spoke 124 is provided at the middle position of the sliding compound door, longitudinally passing through four horizontal rows, and each left and right row of the longitudinal spokes 124 respectively includes two sub-doors 121 and one flow ring 122, or two flow rings 122 and one sub-door 121. It can be understood that the provision of the longitudinal spokes 124 can effectively increase the strength of the sliding compound door, and can ensure the precision of fine machining and micron fine machining of the compound door plane during production and manufacturing, and can also ensure the airtight water-stopping effect of the end face seal.
[0139] In this embodiment, the sliding cavity 110 further includes a linear motor 140, which is arranged in the space between the upper surface of the top beam 1231 and the inner wall of the sliding cavity, and in the space between the lower surface of the bottom beam 1232 and the inner wall of the sliding cavity. It can be understood that the movers of the upper and lower linear motors are respectively connected to the top beam 1231 and the bottom beam 1232, so that the sliding door 120 can be driven to perform reciprocating linear motion in the sliding cavity 110 according to the rhythm of water hammer, such as Figure 1 As shown, the upper surface of the top beam 1231 and the lower surface of the bottom beam 1232 correspond to the positions of the first current-passing column 1101 and the second current-passing column 1102, respectively, and the movers of the linear motors are arranged accordingly. In this way, the driving force given to the sliding compound door is overall balanced, so as to stably drive the movement of the sliding compound door, and the force on the sliding compound door is balanced from the perspective of the motor driving force.
[0140] In this embodiment, the electromagnetic locking assembly 150 includes a U-shaped rail integrated with the crossbeam 123. Therefore, it can be understood that there are 5 U-shaped rails 153 on the front and rear sides of the sliding double door 120 and an electromagnet 152 arranged on the inner wall of the sliding cavity 110 corresponding to the position of each U-shaped rail 153. The front and rear end faces of the U-shaped rail 153 are formed with grooves of the U-shaped rail, and the grooves are facing the front / rear direction.
[0141] In this embodiment, the inner wall of the sliding cavity 110 is preset with a groove, and the electromagnet 152 is integrally built into the groove, and the electromagnet 152 protrudes from the inner wall of the sliding cavity 110 but maintains a 5mm spacing with the rail 153, ensuring that the sliding movement of the sliding door is not affected while working. The electromagnet 152 is an iron core 1522 sandwiched between the upper and lower side pole plates 1521 and a coil (not shown in the figure) is wrapped around the iron core, and its horizontal extension length is slightly less than the horizontal length of the inner wall of the sliding cavity, and the spacing between the upper and lower side pole plates 1521 is equal to the opening height of the notch of the U-shaped track.
[0142] It is necessary that the positions of the electromagnets 152 and the U-shaped rails 153 are arranged corresponding to each other. As can be seen from the above structural description, the sliding double door 120 includes 5 crossbeams 123, and the front and rear end surfaces of each crossbeam 123 are U-shaped rails 153, and each U-shaped rail 153 corresponds to a groove and an electromagnet 152 built in the groove. Therefore, it can be understood that, based on the sliding double door 120, the U-shaped rails 153 on the front and rear sides are symmetrically arranged, and the grooves on the front and rear sides and the electromagnets on the front and rear sides are also symmetrically arranged. Figures 1 to 5BIn the specific structure shown, the two rows of electromagnets 152 respectively correspond to the opening walls of the front and rear U-shaped track grooves, that is, the electromagnetic locking assembly 150 as a whole is constructed as a bilaterally symmetrical electromagnetic locking structure, which is beneficial to maintaining the stability of the relative position between the sliding compound door 120 and the sliding cavity 110 in the moving state / locked state, correcting the offset, and at the same time being able to withstand the impact of water flow to a certain extent.
[0143] As shown in the figure, a fixed rail 151 is arranged in the notch of the U-shaped track, and is made of non-magnetic material. A lubricating guide shoe 1511 is embedded in the fixed rail 151 on one side facing the bottom of the U-shaped groove.
[0144] It can be understood that the flow ring 122 of the sliding compound door 120 matches the end face shape and size of the flow channel assembly 111 of the sliding chamber 110. Specifically, the flow ring 122 is an annular structure with an elliptical circular cross section, and the flow channel assembly 111 is an annular columnar structure with an elliptical cross section, so that when the sliding compound door 120 slides to any phase locking door position, the flow ring 122 and the annular end face of the flow channel assembly 111 just overlap, so that the flow channel is connected.
[0145] It is understandable that the sub-door 121 of the sliding compound door 120 matches the end surface shape and size of the flow passage assembly 111 of the sliding chamber 110. Figure 1 and Figure 4 As shown, the cross-sectional shape of the sub-gate 121 is a rectangle, wherein the transverse side is the long side and the longitudinal side is the short side, and the dimension of the short side is slightly larger than the length of the major axis of the cross-sectional area of the flow channel assembly. When the sliding compound door 120 slides to any phase locked door position, a portion of the flow channel is in a non-through state, and the size of the sub-gate 121 can cover the elliptical annular end face of the flow channel assembly 111 to block the flow of water through the flow channel.
[0146] On the basis of this structure, when the sliding gate 120 slides to any phase locking position, a part of the flow channel is in a through state, and the flow ring 122 can just coincide with the end face of the corresponding flow channel component 111. Combined with the end face sealing structure, the water flow and sealing can be guaranteed to the greatest extent, thereby realizing the "opening" of the flow channel. At the same time, the sub-gate 121 can completely block the end face of the corresponding flow channel component 111, thereby blocking the water flow through the flow channel and realizing the "closing" of the flow channel. The reciprocating motion of the sliding gate 120 enables each flow channel to be alternately "opened" and "closed", thereby realizing the flow conversion function of the flow conversion valve.
[0147] In this embodiment, the sliding cavity 110 is formed by a sealed housing 112, and the sliding gate 120, the flow channel assembly 111, the dewar 131, the electromagnet 152, and the linear motor 140 are all accommodated in the sliding cavity 110 in the housing 112, so that the overall sealing of the electromagnetic commutation structure can be achieved. Among them, since the flow channel needs to be through the front and rear directions to allow water to pass through, the end of the flow channel assembly 111 is formed as a through hole on the housing 112.
[0148] The present application also provides a commutation valve having a commutation structure using the above-mentioned quantum electromagnetic suspension coupling locking technology, such as Figure 6 As shown, the flow conversion valve includes a water inlet 200, a water outlet 300 and a flow conversion part 100. The flow conversion part 100 is arranged between the water inlet 200 and the water outlet 300. The flow conversion part 100 includes the flow conversion structure as described above.
[0149] Combination Figure 6 , Figures 8 to 10 As shown, in this embodiment, the water inlet part 200 includes a plurality of water inlet chambers 210, each of the water inlet chambers 210 includes a water inlet 211 and two transversely arranged water outlets 212, and the two transversely arranged water outlets 212 are connected to each of the flow channels in the adjacent first flow column 1101 and the second flow column 1102 in the sliding cavity 110 of the flow conversion structure.
[0150] Combination Figure 6 , Figures 11 to 13 As shown, in this embodiment, the water outlet part 300 includes a plurality of water outlet chambers 310 , each of the water outlet chambers 310 includes a water outlet 312 and two longitudinally arranged water inlets 311 , and the two longitudinally arranged water inlets 311 are connected to two adjacent flow channels in a vertical column in the sliding cavity 110 .
[0151] The reversing re-valve of the present application is applied to a water delivery and drainage system of double PCCP pipes, which includes a first PCCP pipe and a second PCCP pipe upstream, a downstream water lifting pipe and a downstream drainage pipe downstream. The water outlet ends of the first PCCP pipe and the second PCCP pipe are connected to the water inlet 200 of the reversing re-valve, and the water inlet ends of the downstream water lifting pipe and the downstream drainage pipe are connected to the water outlet 300 of the reversing re-valve.
[0152] In this embodiment, half of the water inlets in the water inlet portion 200 of the converter reversing valve are connected to the first PCCP pipe, and the other half of the water inlets are connected to the second PCCP pipe.
[0153] Specific combination Figures 8 to 10In the structure shown, the water inlet 200 includes 8 water inlet rooms 210, which are arranged in four rows horizontally. Accordingly, the water inlets 211 of the 8 water inlet rooms 210 are also arranged in four rows horizontally. The four water inlets 211 in the top and bottom rows are connected to the first PCCP pipe, and the four water inlets in the middle two rows are connected to the second PCCP pipe. The water outlets 212 of the 8 water inlet rooms 210 correspond to the 16 flow passages arranged in four columns.
[0154] In this embodiment, half of the water outlets in the water outlet portion 300 of the flow conversion reversing valve are connected to the downstream water lifting pipe, and the other half of the water outlets are connected to the downstream drainage pipe.
[0155] Specific combination Fig.11 and Fig.13 In the structure shown, the water outlet 300 includes 8 water outlet chambers 310, which are arranged in four columns in the longitudinal direction. Accordingly, the water outlets 312 of the 8 water outlet chambers 310 are also arranged in four columns in the longitudinal direction. The 4 water outlets 312 on the left and right sides corresponding to the first flow column 1101 are connected to the downstream water outlet pipe as water pumping gates, and the 4 water outlets 312 in the middle two columns corresponding to the second flow column 1102 are connected to the downstream drainage pipe as drainage gates. The water inlets 311 of the 8 water outlet chambers 310 correspond to the 16 flow passages arranged in the four columns.
[0156] Since the above-mentioned flow conversion structure also includes the middle vacant column and the first and second vacant columns on both sides, the width range of the water inlet room and the water outlet room can cover the width of the vacant column, and can have a certain water flow buffering function and a reasonable layout of the overall appearance structure.
[0157] The above describes the preferred embodiments from a structural perspective in combination with the commutation structure and commutation re-valve structure shown in the accompanying drawings. For easier understanding, the distribution of the flow passages is explained below from a functional perspective.
[0158] Figure 14 to Figure 15 It is a plan view of the distribution of flow channels viewed from the water inlet direction. The flow channels are appropriately numbered in the figure. It should be noted that such numbering is only for the convenience of subsequent description of the process to assist understanding.
[0159] From the functional point of view, each flow channel a is defined as the water-lifting gate position for water inlet of the first PCCP pipe, and each flow channel b is defined as the water-draining gate position for water inlet of the first PCCP pipe; each flow channel c is defined as the water-lifting gate position for water inlet of the second PCCP pipe, and each flow channel d is defined as the water-draining gate position for water inlet of the second PCCP pipe. The "water-lifting gate position" function here is based on the water-lifting function realized by the first flow column 1101 in this embodiment being connected to the downstream water-lifting pipe, and the "draining gate position" function is based on the drainage function realized by the second flow column 1102 in this embodiment being connected to the downstream drainage pipe.
[0160] In conjunction with the accompanying drawings, the flow channel 1a, the flow channel 1b, the flow channel 1c, and the flow channel 1d form a small-scale flow conversion combination (or can be understood as a single valve). For the sake of convenience, it is referred to as the first combination. In the first combination, the flow channel 1a on the left side is the first PCCP pipe water inlet-water lifting channel, the flow channel 1b on the right side is the first PCCP pipe water inlet-water discharge channel, the flow channel 1c on the left side is the second PCCP pipe water inlet-water lifting channel, and the flow channel 1d on the right side is the second PCCP pipe water inlet-water discharge channel.
[0161] Similarly, the flow passage 2a, the flow passage 2b, the flow passage 2c, and the flow passage 2d also form a small flow conversion combination, referred to as the second combination, which is located on the right side of the first combination; the flow passage 3a, the flow passage 3b, the flow passage 3c, and the flow passage 3d form a third combination, which is located on the lower side of the first combination; the flow passage 4a, the flow passage 4b, the flow passage 4c, and the flow passage 4d form a fourth combination, which is located on the lower side of the second combination and on the right side of the third combination. Whether from the above structure or from the water intake, water lifting, and water discharge functions, the first combination and the second combination are symmetrical with respect to the longitudinal direction, the third combination and the fourth combination are symmetrical with respect to the longitudinal direction, and the first combination and the second combination are symmetrical with respect to the transverse direction, and the third combination and the fourth combination are symmetrical with respect to the transverse direction, or the first combination to the fourth combination are set to be centrally symmetrical with the center point of the middle vacant row as the reference, which can correspond to the "complex valve flow conversion valve with four single valves arranged in a strict two-dimensional symmetry (central symmetry) combination according to the flow port 2×2" in the aforementioned principle.
[0162] Correspondingly, it can be understood that the flow channels 1a, 1c, 3c, 3a are located in the first vertical column 1101 on the left side of the sliding cavity 110, the flow channels 1b, 1d, 3d, 3b are located in the second vertical column 1102 on the left side of the sliding cavity 110, the flow channels 2a, 2c, 4c, 4a are located in the first vertical column 1101 on the right side of the sliding cavity 110, and the flow channels 2b, 2d, 4d, 4b are located in the second vertical column 1102 on the right side of the sliding cavity 110.
[0163] The arrangement of the above-mentioned flow channel, in conjunction with the sliding compound gate composed of a sub-gate and a flow ring, can achieve self-balancing (counterbalancing) of the static water hammer pressure of the sliding compound gate, that is, the sliding compound gate has the characteristics of 0 force and 0 moment, and when the inner wall of the flow port is elliptical, the static water pressure of the combined gate during sliding is also completely self-balanced, that is, the dynamic pressure of the water flow of the sliding compound gate is counterbalanced with the help of magnetic suspension.
[0164] During operation, when the sliding door 120 is in the Fig.14 When the first phase is locked at the gate position, it can be seen that the sub-gates block the gate positions of the flow channels 1c, 3c, 2c, 4c of the first flow column 1101 and the flow channels 1b, 3b, 2b, 4b of the second flow column 1102. At the same time, the flow channels 1a, 3a, 2a, 4a of the first flow column 1101 and the flow channels 1d, 3d, 2d, 4d of the second flow column 1102 are aligned with the flow ring and connected to allow water to flow through, and the additional sub-gates block the flow channels 1c, 3c, 2c, 4c of the first flow column 1101 and the flow channels 1b, 3b, 2b, 4b of the second flow column 1102. The gate and the flow ring are located in the middle vacant column 1103 and the second vacant column 1105 on the right, so that the first PCCP pipe can pump water to the downstream water pumping pipe through the flow channels 1a, 3a, 2a, and 4a, and drain water to the downstream drainage pipe through the flow channels 1d, 3d, 2d, and 4d. At this time, the corresponding Dewar and the double-sided permanent magnet rails perform quantum locking on the sliding compound gate, and the electromagnets and rails that are energized at the same time realize bilateral offset correction of the sliding compound gate through electromagnetic suspension induction.
[0165] According to the water hammer rhythm requirement, the sliding compound door 120 is driven by the linear motor 140 to move leftward from the position of the first phase locking door position to the position of the first phase locking door position. Fig.15 The position of the second phase locking door position shown in the figure shows that the sub-gate blocks the flow channels 1a, 3a, 2a, 4a of the first flow column 1101 and the flow channels 1d, 3d, 2d, 4d of the second flow column 1102. At the same time, the flow channels 1c, 3c, 2c, 4c of the first flow column 1101 and the flow channels 1b, 3b, 2b, 4b of the second flow column 1102 are aligned with the flow ring to allow water to flow through, and the additional The sub-gates and the flow rings are located in the middle vacant column 1103 and the first vacant column 1104 on the left, so that the first PCCP pipe can pump water to the downstream water pumping pipe through the flow channels 1c, 3c, 2c, and 4c, and drain water to the downstream drainage pipe through the flow channels 1b, 3b, 2b, and 4b. At this time, the corresponding Dewars and double-sided permanent magnet rails perform quantum locking on the sliding compound gate, and the electromagnets and rails that are energized at the same time perform bilateral offset correction on the sliding compound gate through electromagnetic suspension induction.
[0166] According to the above description of the commutation switching process, it can be understood that the linear motor 140 can drive the sliding gate 120 to reciprocate in the sliding cavity 110, and the quantum locking component and the electromagnetic locking component lock the sliding gate in the first phase locking gate position or the second phase locking gate position during the reciprocating motion, so that the sub-gates and the flow rings of the sliding gate can overlap with the corresponding flow channel components 111 respectively. When the gate is in the first phase locking position, part of the flow channel is connected front to back, and the other part of the flow channel is blocked by the sub-gate, and when switching to the second phase locking position, the through and blocking states of the flow channel are exchanged, thereby realizing the switching of the water lifting and drainage strokes in the valve.
[0167] The electromagnetic commutation structure and electromagnetic commutation valve according to the present application are described in detail by way of example only. These examples are only used to illustrate the principle and implementation method of the present application, but not to limit the present application. Without departing from the spirit and scope of the present application, those skilled in the art can also make various modifications and improvements. Therefore, all equivalent technical solutions should belong to the scope of the present invention and be defined by the claims of the present application.
