The self-balancing water hammer static pressure of the sliding conversion door structure greatly shares, reduces and even completely eliminates the load of the electromagnetic floating quantum locking conversion door which overcomes the water hammer load, saves power, and facilitates the linear motor driving sliding according to the water hammer rhythm. In particular, during each water hammer water lifting period, the self-balancing water hammer static pressure of the conversion door structure can reduce the quantum locking output, so as to eliminate the electromagnetic floating output, and realize the minimization of the quantum electromagnetic locking load.

[0063] The application provides a commutation complex valve structure using electromagnetic suspension and high-temperature superconducting magnetic suspension coupling locking (electromagnetic quantum coupling locking) technology, which is mainly applied to a long-distance double PCCP water hammer water lifting system. The electromagnetic suspension and high-temperature superconducting magnetic suspension coupling locking (electromagnetic quantum coupling locking) technology can be understood as follows: the electromagnetic suspension is actually a high-frequency and high-precision sensing of the distance between the rail and the electromagnetic pole plate, and the dynamic stability of the air gap distance between the rail and the pole plate is achieved by controlling and adjusting the excitation current of the electromagnet by the power electronic control device (magnetic suspension controller). The high-temperature superconducting magnetic suspension refers to the interaction between high-temperature superconducting and permanent magnets to achieve stable self-suspension, which has the advantages of high efficiency and stable and reliable process. Specifically, the commutation complex valve of the application mainly adopts a double-sided quantum locking mode, cooperates with the electromagnetic suspension mode, and achieves the technical purpose of stable movement and locking of the sliding complex door in the valve body. Specifically, the sliding complex door is symmetrically arranged with quantum locking components (Dewar and permanent magnet rail) and electromagnetic locking components (U-shaped electromagnet and U-shaped rail) on both sides, which serve as door position locking components. The commutation sliding complex door of the commutation complex valve can be strictly locked at the center door position of the upward water flow, the mechanical load bearing of the sliding complex door water hammer half-cycle shuttle weaving movement commutation does not occur, mechanical friction does not occur, which is beneficial to long-term operation, provides technical support for the gate type or sealing type pressure water dynamic seal, and is beneficial to improving the efficiency.

[0064] The quantum locking assembly is arranged on the front and rear sides (i.e. both sides) of the sliding complex valve, so that (pure) quantum locking can be achieved without the need for auxiliary sensing feedback control; or the electromagnetic locking assembly is arranged on the front and rear sides (i.e. both sides) of the sliding complex valve, and the electromagnetic output is adjusted and controlled through the magnetic floating distance and quantum locking output sensing, so that the quantum electromagnetic coupling locking can correct the 0 offset distance of the complex valve center door position in each sensing feedback control cycle, that is, the electromagnetic quantum coupling strict locking of the converter complex valve center door position can be achieved; or the electromagnetic locking assembly and high-frequency sensing can be used to achieve pure electromagnetic locking of the complex valve. It is worth mentioning that the quantum and electromagnetic coupling locking complex valve is a stable control system, which can strictly lock with ±0.01mm accuracy, and the stability of the locking center door position is better than that of pure electromagnetic floating.

[0065] The linear motor driven built-in sliding complex valve makes shuttle weaving reciprocating motion according to the half cycle of water hammer, and cooperates with the specially designed static self-balancing converter complex valve body structure and the flow passage design, so that the switching of the double-pipe water conveying to downstream water lifting and drainage process can be achieved, the operation process is easy to control, the impact on the valve body and pier and the pipeline can be reduced through the above design, and the water utilization rate can be controlled to realize the self-balance of the combined sliding complex valve static water hammer pressure, and the safety and stability of the system are improved; the quantum electromagnetic coupling locking can overcome the 32-meter water pressure conversion, so that the corresponding PCCP pressure pipeline is matched, and the water lifting capacity of 32 meters of higher water lifting head can be achieved.

[0066] The application provides a converter structure and a converter complex valve applying quantum locking and auxiliary electromagnetic locking.

[0070] The quantum locking assembly 130 comprises a corresponding arrangement of the duvets 131 and the permanent magnetic rails 132 in the front-rear direction, and each of the upper and lower edges of the one overcurrent channel assembly 111 is provided with a group of duvet groups, each of the duvet groups comprises two duvets 131 arranged on the front side and the rear side of the gap, and each of the upper and lower edges of the sliding door 121 is provided with one of the permanent magnetic rails 132, and the permanent magnetic rail 132 is located between the two corresponding duvets 131. It can be understood that the permanent magnetic rail 132 is a double-sided permanent magnetic rail, which forms a symmetrical and stable quantum locking relationship with the two corresponding duvets 131 arranged in the front-rear direction.

[0071] The linear motor 140 is connected with the sliding cavity 110 and the sliding door 120, so that the linear motor 140 can drive the sliding door 120 to make reciprocating shuttle movement in the sliding cavity 110 as a shuttle driving assembly.

[0075] According to a preferred embodiment of the present application, the overcurrent channel assembly 111 is specifically configured as a structure as shown in Figures 1 to 3 The outer wall is circular and the inner wall is elliptical, and the major axis of the ellipse is arranged in the horizontal transverse direction. Such shape not only thickens the wall thickness of the channel assembly, which can withstand greater water flow impact, but also provides accommodation positions for the permanent magnetic rails arranged on the upper and lower edges. This will be described in more detail below.

[0076] According to other embodiments of the present application, the shape of the outer wall of the overcurrent channel assembly 111 can also be selectively configured as a circle, a rectangle, a square or other polygonal shapes according to different needs.

[0077] It should be noted that the outer wall and inner wall shape of the flow passage assembly 111 refers to the outer edge shape and inner edge shape of the flow passage assembly in the cross-sectional direction.

[0078] According to a preferred embodiment of the present application, the sliding cavity 110 includes 16 flow passages.

[0079] The first flow columns 1101 and the second flow columns 1102 can correspond to the water lifting function and the water draining function, respectively, or correspond to the water draining function and the water lifting function, respectively.

[0080] According to an embodiment of the present application, the sliding complex door 120 adopts a complex door structure, wherein the sliding complex door 120 includes a plurality of sub-doors 121 and flow rings 122, which are arranged in a spaced manner and matched with the arrangement manner of the flow passages.

[0081] According to a preferred embodiment of the present application, the sliding complex door 120 includes 12 sub-doors 121 and 12 flow rings 122. Figure 4 In the illustrated embodiment, the sub-doors 121 and the flow rings 122 of the sliding complex door 120 are arranged as four horizontal rows, and the sub-doors 121 and the flow rings 122 in each horizontal row are arranged in a mutually spaced and staggered manner, wherein the top horizontal row and the bottom horizontal row are a first horizontal row 1201 having the same arrangement manner, two second horizontal rows 1202 having the same arrangement manner are arranged between the two first horizontal rows 1201, and the arrangement manner of the sub-doors 121 and the flow rings 122 in the first horizontal row 1201 and the second horizontal row 1202 is mutually staggered. The flow rings 122 have a ring structure corresponding to the ring column structure of the flow passage assembly 111, and the vertical direction height of the flow rings 122 is not greater than the height of the sub-door 121. For details, refer to Figure 4In the shown embodiment, the first horizontal row 1201 at the top is arranged with the sub-door 121 and the flow ring 122 from left to right in sequence, and the second horizontal row 1202 below the first horizontal row 1201 is arranged with the flow ring 122 and the sub-door 121 from left to right in sequence. The arrangement of the sub-door and the flow ring in the first horizontal row 1201 and the second horizontal row 1202 is different, and thus the arrangement of the sub-door and the flow ring in the first horizontal row 1201 and the second horizontal row 1202 is staggered. In this way, the switching between the flow channels with the water lifting / discharging function during the sliding can be reasonable.

[0082] Preferably, the cross section of the flow ring 122 is selected to be the same as the shape of the inner wall of the flow channel. In particular, the inner wall shape of the flow ring 122 is completely the same as the inner shape of the flow channel, so that the flow ring 122 is completely aligned with the flow channel to allow the water to pass through without any obstruction, 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.

[0084] The upper edge and the lower edge of each horizontal row of the sliding complex door 120 are provided with a cross beam 123, and the left and right sides of the sliding complex door between at least the adjacent sub-door and the flow ring are provided with a longitudinal spoke 124. The cross beam 123 and the longitudinal spoke 124 form an overall frame structure connecting the sub-door and the flow ring.

[0085] The cross beam 123 can be configured as a plate structure with a suitable thickness, and the sub-door and the flow ring are connected to the cross beam and fixed between adjacent cross beams, so as to connect and fix the sub-door 121 and the flow ring 122 to each other, thereby forming an overall structure of the sliding complex door. According to the structure shown in the illustrated embodiment, the plurality of cross beams 123 are uniformly distributed, and the extension of the cross beam 123 is along the transverse direction and the front-back direction.

[0086] In some embodiments, the cross beam 123 can be a hollow structure, which is conducive to the water flow in the sliding cavity during the sliding of the sliding complex door.

[0087] According to a preferred embodiment of the present application, the sliding complex door 120 includes five cross beams 123, as shown in the specific embodiment. Figure 4 In the shown embodiment, three cross beams 123 are arranged as middle beams 1233 respectively sandwiched between two first horizontal rows 1201 and two second horizontal rows 1202, and the remaining two cross beams 123 are arranged as top beams 1231 and bottom beams 1232 respectively arranged at the top of the upper first horizontal row 1201 and the bottom of the lower second horizontal row 1202, i.e. as the outer frame of the top and bottom of the sliding complex door.

[0088] According to an embodiment of the present application, the crossbeam 123 can be configured as a fused rail structure, which will be described in detail later.

[0089] As an optional embodiment, the longitudinal spoke 124 located at the middle position can be arranged in only one cross row or through at least two cross rows as needed. The longitudinal spoke 124 can increase the overall strength of the sliding complex door, and ensure the precision of the finishing and micron finishing of the complex door plane during production and manufacturing, and also ensure the sealing and water-stopping effect of the end face sealing.

[0090] According to an embodiment of the present application, the Dewar 131 is arranged at the upper edge and the lower edge of the flow passage assembly 111. Based on the gap, the flow passage assembly 111 is divided into two parts, and a set of Dewars is correspondingly arranged at the upper side walls of the two flow passage assemblies, that is, two Dewars 131 in the set of Dewars are respectively embeddedly arranged at the upper side walls of the flow passage assemblies 111 on the front and rear sides of the gap. Similarly, a set of Dewars is correspondingly arranged at the lower side walls of the two flow passage assemblies, that is, two Dewars 131 in the set of Dewars are respectively embeddedly arranged at the lower side walls of the flow passage assemblies 111 on the front and rear sides of the gap, and the two Dewars 131 in each set of Dewars are arranged in front and rear positions based on the central cross-sectional direction of the sliding complex door.

[0091] It can be understood that, during the sliding and locking process of the quantum locking assembly, the Dewar 131 and the permanent magnet rail 132 are not in contact and have no friction therebetween, and therefore a gap is required between the Dewar 131 and the permanent magnet rail 132. In this embodiment, the gap between the permanent magnet rail 132 and one side Dewar 131 is 5mm±2mm, and the gap between the permanent magnet rail 132 and the other side Dewar 131 is 5mm±2mm, that is, the sum of the two gaps between the permanent magnet rail 132 and the two side Dewars 131 is 10mm.

[0092] As shown in the embodiment, Figure 2 Because the flow passage assembly 111 is configured as a ring column 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 thickness of the flow passage assembly 111 in the upper and lower directions is relatively large, obviously larger than the wall thickness in the left and right directions. The installation groove is arranged at the position of the thick wall in the upper and lower directions of the outer wall, and the Dewar 131 is embedded in the installation groove. Therefore, the upper and lower walls of the flow passage assembly 111 are embedded with Dewars 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 magnet rail 132 is arranged on the sliding complex door 120. Specifically in combination with Figure 4 , Figure 5AIn the shown embodiment, the permanent magnet rails 132 are arranged on the upper and lower sides of the sub-door 121 and the flow-through ring 122 in the same horizontal row, and when the sliding complex door 120 is installed in the gap of the sliding cavity 110, the positions of the permanent magnet rails 132 are located between the front and rear two Dewars 131 of the corresponding set of Dewar groups. It can be understood that the front and rear surfaces of the permanent magnet rails 132 are kept at a small distance from the corresponding Dewars 131 to meet the requirement of relative sliding.

[0094] Optionally, the upper edge, the lower edge, the left edge, and the right edge of the flow-through ring 122 can be directly or through connecting elements 1221 connected with the permanent magnet rails 132, the sub-door 121, and the longitudinal spokes 124. The permanent magnet rails 132 can also be directly or through suitable connecting elements connected with the sub-door 121 and the longitudinal spokes 124. It can be understood that according to the actual situation of the valve body application, radial spokes (not shown in the figure) can also be added in the ring, extending from the geometric center of the ellipse to the flow-through ring 122, and then extending to the connection positions of the longitudinal spokes and / or the sub-door, to further ensure the rigidity of the flow-through ring.

[0095] The permanent magnet rails 132 in the same horizontal row can be the same length as the crossbeam 123 of the sliding complex door. The whole permanent magnet rails 132 can be in an integrated state, or the permanent magnet rails 132 in the same horizontal row can be spliced by six short permanent magnet rails with lengths equal to the width of the first / second flow-through longitudinal row, which is more convenient for transportation and repair.

[0096] Suitably, the permanent magnet rails 132 adopt halbach permanent magnet rails. A protection plate can be additionally arranged in the sliding complex door, and the permanent magnet rail segments and the sub-door can be installed in the protection plate. In other words, the protection plate can be configured as a thin plate with the same shape as the front side and the rear side of the permanent magnet rails and the sub-door, so as to make the installation of the permanent magnet rails and the sub-door more stable and also play a protection role. Alternatively, the protection plate is formed in an integrated structure with the sub-door, and extends upward and downward from the front side and the rear side of the sub-door to the position of the crossbeam, and there is a containing space between the front side and the rear side protection plates for containing the permanent magnet rails (not shown in the figure), so that the installation and protection of the permanent magnet rails 132 can also be achieved.

[0097] According to the structure design of the above-mentioned quantum locking assembly 130, it can be known that due to the physical properties between the Dewar and the permanent magnet, i.e., the high-temperature superconductor can strictly quantum lock the permanent magnet in a constant low-temperature environment, the permanent magnet rails 132 are stably moved and locked between the Dewars 131 by means of the above-mentioned physical properties, and the sliding complex door can stably perform horizontal reciprocating motion in the sliding cavity and be locked at the required position.

[0098] The Dewar 131 can adopt an existing Dewar arrangement, in which the interior is uniformly provided with superconductors, such as YBaCuO high-temperature superconductor blocks, etc., and the permanent magnet rail 132 can adopt a neodymium-iron-boron permanent magnet rail, etc. The Dewar and the permanent magnet have been used in the field of magnetic levitation trains, and thus the selection of the Dewar and the permanent magnet can be made according to the technical knowledge of those skilled in the art and the actual engineering needs, and is not limited herein.

[0099] According to an embodiment of the present application, the sliding cavity 110 is also secondarily provided with a linear motor 140, which is arranged in the space between the top and / or bottom of the sliding complex door 120 and the inner wall of the sliding cavity. It can be understood that the linear motor can be connected to the top and / or bottom of the sliding complex door 120, and can drive the sliding complex door 120 to move in the sliding cavity 110 in a reciprocating linear motion according to the water hammer rhythm. The installation structure of the linear motor can be reasonably arranged according to the conventional technical knowledge of those skilled in the art, and thus is not specifically described herein.

[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 complex 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 complex 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 complex door 120 to move in the sliding cavity 110 in a reciprocating linear motion according to the water hammer rhythm.

[0101] As shown in Figure 1 , the top beam 1231 upper surface and the bottom beam 1232 lower surface are respectively arranged with the movers of the linear motors corresponding to the positions of the first and second flow columns 1101 and 1102. In this way, the driving force of the sliding complex door is balanced as a whole, so as to stably drive the movement of the sliding complex door, and the stress on the sliding complex door is balanced from the perspective of the driving force of the motor.

[0102] According to an embodiment of the present application, the commutation structure is also provided with an electromagnetic locking assembly 150, and the rail 153 of the electromagnetic locking assembly 150 is integrally made with the cross beam 123 in a fusion rail manner, as shown in Figure 5BThe rail 153 forms a U-shaped track at the front and rear end faces of the beam 123, with the notches facing the front / rear direction. The inner wall of the sliding cavity 110 is provided with a groove, and the electromagnet 152 of the electromagnetic locking assembly 150 is embedded in the groove. The electromagnet 152 is arranged in such a manner that the iron core 1522 is sandwiched between the upper and lower side plates 1521, and a coil (not shown in the figure) is wound around the outer periphery of the iron core. The positions of the upper and lower side plates 1521 correspond to the upper and lower edges of the notches of the U-shaped track, respectively, and the distance between the upper and lower side plates 1521 can be equal to the height of the notches of the U-shaped track. The gap between the side plates 1521 of the electromagnet 152 and the rail 153 is 5mm±2mm, and preferably, the distance is 5mm for optimal relative sliding.

[0103] In operation, the upper and lower edges of the notches of the U-shaped track work in pairs with the fixed electromagnet side plates, i.e., relative movement occurs through electromagnetic induction. During the movement, the rail does not contact and rub against the electromagnet. The electromagnet 152 can be laterally extended to be equal to or slightly smaller than the lateral length of the inner wall of the sliding cavity, as long as it can realize electromagnetic induction with the rail 153 and ensure the function of correcting the offset distance of the electromagnetic induction assembly.

[0104] More preferably, as shown in Figure 4 、 Figure 5A and Figure 5B , a fixed rail 151 is arranged in the notch of the U-shaped track. The fixed rail 151 is a non-magnetic sliding rail, i.e., 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 notch and works in pairs, sharing the electromagnetic load overload, and completely bearing the main load when the electromagnetic fails. When the fixed rail 151 is selected as a sliding guide rail, there is sliding friction, and when the fixed rail 151 is selected as a rolling guide rail, there is rolling friction. More preferably, a lubricating guide shoe 1511, a roller (roller or needle) or a sliding rail sleeve can be embedded in the side of the fixed rail 151 facing the bottom of the U-shaped notch. The guide shoe can be made of low-friction coefficient synthetic materials such as copper-embedded graphite, copper-carbon powder alloy, iron pear wood, and water-lubricated rubber, thereby achieving lubricated and low-friction sliding.

[0105] It is necessary that the electromagnet 152 and the rail 153 are arranged in corresponding positions. Specifically, the number of grooves arranged on the inner walls of the front side and the rear side of the sliding cavity 110 is the same as the number of the cross beams 123, and the distance between adjacent grooves is equal to the distance between the cross beams, so that the electromagnet 152 built in the groove can correspond to the plurality of rails 153 one by one, which is beneficial to assist in correcting the offset of the relative position of the sliding complex 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 integrally manufactured with the shell 112, and the electrical core and the excitation wire package can be placed in the protection space of the outer isolation wall of the sliding cavity because they can be separated from the pole plate 1521, which is beneficial to insulation protection.

[0106] In the present application, the electromagnetic locking assembly 150 serves as an auxiliary stable active control system for correction of the offset distance. Specifically, the offset distance of the sub-door unit is obtained by sensing, and according to the offset distance, it is known how much the quantum output is offset, how much the quantum locking force is greater than the offset distance, and then the electromagnet 152 is fed back and the electromagnet 152 increases the force by this amount. The quantum output can return to the quantum output without offset distance, and the door position 0 offset correction in the sensing cycle is realized. In other words, when the locking ability of the self-stable quantum locking assembly 130 is insufficient to strictly lock the door position of the sliding complex door 120, that is, when the sliding complex door is laterally offset due to water flow impact, the electromagnetic locking assembly 150 can further actively control and adjust the electromagnetic force to make the sliding complex door resist the offset force and correct the 0 offset distance. The electromagnet provides auxiliary locking force exceeding the quantum locking ability for high-frequency continuous adjustment, and realizes the coupling of quantum physical characteristics self-locking and electromagnetic active sensing feedback locking in the whole process of commutation sliding. Similar to the track maglev train, the quantum locking and the electromagnetic floating locking also have guiding forces to overcome the disturbance (such as gravity) in the plumb direction of the sliding door, and prevent the upward and downward direction offset movement. Like the horizontal direction main load, in the plumb direction, the slide rail is also coupled with the electromagnet to bear the load, and the slide rail can not bear or bear less mechanically under low disturbance load.

[0107] As a preferred embodiment, the electromagnet 152 and the rail 153 are arranged in front and rear of the sliding complex door 120, and are symmetrically arranged based on the sliding complex door 120. Specifically, as shown in the figure, the electromagnet 152 and the rail 153 are arranged in front and rear of the sliding complex door 120, and are symmetrically arranged based on the sliding complex door 120. Figure 1 and Figure 3As shown, the upper and lower edges of the two first horizontal rows 1201 and the two second horizontal rows 1202 of the sliding complex door are provided with five beams 123. Since the front and rear end faces of the beams 123 are symmetrical, the rails 153 fused to the front and rear end faces of the beams 123 are also symmetrical. The electromagnets 132 corresponding to the rails 153 are also symmetrical relative to the sliding complex door 120. Thus, the electromagnetic locking assembly 150 is symmetrical relative to the sliding complex door, and can realize bilateral 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 overflow ring 122 are matched with the cross-sectional (end face) shape and size of the inner wall of the overflow passage assembly 111. Meanwhile, the cross-sectional shape of the sub-door 121 is a square with a side length greater than the long axis size of the elliptical cross section of the overflow passage assembly 111, or a rectangle with a minimum side size greater than the long axis size of the elliptical cross section of the overflow passage assembly 111. On the basis of this structure, when the sliding complex door 120 moves to the through position, the end face of the overflow ring 122 can just coincide with the end face of the corresponding overflow passage assembly 111, and cooperate with the end face sealing body to maximize the guarantee of water flow and sealing, realize the “opening” of the passage, and at the same time the sub-door can completely block the end face of the corresponding overflow passage assembly, thereby blocking the water flow of the overflow passage and realizing the “closing” of the passage.

[0109] In the above embodiment, the bottom hollowed-out piston or aeroengine case-shaped sealing structure body integrating end face sealing and radial cylindrical sealing is integrated in the overflow passage. The end face sealing structure can adopt graphite ring end face sealing or end face copper-carbon powder metallurgy self-lubricating sealing. The radial sealing can use self-lubricating metal material piston ring sealing, Igus sliding bearing high polymer self-lubricating composite material piston ring, and rolling high polymer O-ring, and is arranged at the end of the overflow port sliding door. The sealing body can be 3D printed like a case, and a wide edge can be added to the parallel end face sealing to resist stress deformation, and a cylindrical sealing is arranged between the two wide edges. The end face sealing structure is tightly attached to the surface of the sub-door and the overflow ring, and can elastically deviate from the balance center by ±5 mm in the upstream and downstream directions (rear and front directions in the application), in addition, the end face of the overflow passage assembly 111 can be structured as a top chamfer, which facilitates the attachment of the sub-door and the overflow ring to the sliding surface. The cylinder body is made of light metal alloy or Igus sliding bearing material, so as to better attach to the inner wall of the overflow passage port, and to realize the micro-distance axial sliding of the electromagnetic control cooperation complex valve flow switching sliding and end face sealing sealing, realize the sealing of the radial cylindrical surface sliding surface gap, and the end face sealing relies on the graphite ring end face to seal the sub-door and the overflow ring, thereby reducing the friction coefficient, reducing maintenance work, improving corrosion resistance, and prolonging the service life.

[0110] According to an embodiment of the present application, as shown in FIG. 1, the overflow passage assembly 111 is provided with a plurality of overflow ports 112, and each overflow port 112 is provided with a sliding complex door 120. Figure 6As shown, the sliding cavity 110 further comprises a housing 112, which serves as a shell to enclose the sliding complex door 120, the flow passage assembly 111, the Dewar 131, the electromagnet 152, and the linear motor 140, so as to realize the sealing of the converter structure. Since the flow passage needs to pass through the front-rear direction to make the water flow through, the end of the flow passage assembly 111 is configured as a through hole on the housing 112.

[0111] The specific shape of the housing 112 is not particularly limited in the present application, as long as the installation and operation of the sliding complex door, the electromagnetic induction assembly, the motor and other components inside can be realized.

[0112] The present application also provides a converter complex valve of the converter structure using the above-mentioned electromagnetic floating quantum coupling locking technology, which comprises a water inlet part 200, a water outlet part 300, and a converter part 100, as shown in Figure 6 As shown in the embodiment, the converter part 100 is arranged between the water inlet part 200 and the water outlet part 300, and the converter part 100 comprises the converter structure as described above.

[0113] According to an embodiment of the present application, the water inlet part 200 comprises a plurality of water inlet rooms 210, each of which comprises one water inlet and two transversely arranged water outlets, which are respectively communicated with each of the first flow passage column 1101 and the second flow passage column 1102 in the sliding cavity of the converter structure.

[0114] According to an embodiment of the present application, the water outlet part 300 comprises a plurality of water outlet chambers 310, each of which comprises one water outlet and two longitudinally arranged water inlets, which are communicated with two adjacent flow passages in a column of the sliding cavity of the converter structure.

[0115] The converter complex valve of the present application is applied to a water delivery and drainage system of a double PCCP pipeline, which comprises an upstream first PCCP pipe and a second PCCP pipe, a downstream water lifting pipe and a downstream drainage pipe. The water outlet ends of the first PCCP pipe and the second PCCP pipe are communicated with the water inlet part 200 of the converter complex valve, and the water inlet ends of the downstream water lifting pipe and the downstream drainage pipe are communicated with the water outlet part 300 of the converter complex valve.

[0116] According to the above-mentioned embodiment of the present application, half of the number of water inlets in the water inlet part 200 of the converter complex valve are communicated with the first PCCP pipe, and the other half of the number of water inlets are communicated with the second PCCP pipe. Specifically, the first PCCP pipe can be communicated with the top and bottom water inlets arranged at intervals, and the second PCCP pipe is communicated with the two rows of water inlets in the middle part.

[0117] Similarly, half of the water outlets in the water outlet part 300 of the valve are connected with the downstream water lifting pipe, and the other half are connected with the downstream drainage pipe. Specifically, the downstream water lifting pipe can be connected with the leftmost and rightmost water outlets arranged at intervals, and the downstream drainage pipe can be connected with the two rows of water outlets in the middle part. Of course, the opposite arrangement can also be made, that is, the downstream drainage pipe is connected with the leftmost and rightmost water outlets arranged at intervals, and the downstream water lifting pipe is connected with the two rows of water inlets in the middle part. The above connection mode can be specifically designed according to the actual environment and the upstream and downstream pipe arrangement mode.

[0118] According to a preferred embodiment of the present application, as shown in Figures 6 to 10 The water inlet part 200 includes eight water inlet rooms 210, which are arranged transversely in four rows. Accordingly, the water inlets of the eight water inlet rooms 210 are also arranged transversely in four rows. The water outlets of the eight water inlet rooms 210 correspond to the 16 flow channels arranged longitudinally in four rows, respectively. In this embodiment, the four first water inlets 2111 arranged in the top and bottom two rows are connected with the first PCCP pipe, and the four second water inlets 2112 arranged in the middle two rows are connected with the second PCCP pipe.

[0119] According to a preferred embodiment of the present application, as shown in Figure 6 , Figure 7 , Figures 11 to 13 The water outlet part 300 includes eight water outlet rooms 310, which are arranged longitudinally in four columns. Accordingly, the water outlets of the eight water outlet rooms 310 are also arranged longitudinally in four columns. The water inlets of the eight water outlet rooms 310 correspond to the 16 flow channels arranged longitudinally in four rows, respectively. In this embodiment, the four water outlets arranged in the left and right two columns are connected with the downstream water lifting pipe as water lifting outlets 3121, and the four water outlets arranged in the middle two columns are connected with the downstream drainage pipe as drainage outlets 3122. Of course, the opposite connection can also be made.

[0120] It can be understood that for a single water inlet room 210, the longitudinal cross section of the water inlet room 210 gradually increases in the direction from the water inlet to the water outlet; for a single water outlet room 310, the longitudinal cross section of the water outlet room gradually decreases in the direction from the water inlet to the water outlet. For the whole valve, the cross-sectional area in the front-rear direction of the chamber gradually changes, which is beneficial to the automatic adjustment of the internal flow field and the maintenance of the micro-momentum balance, has a certain water flow buffering function, and has a reasonable layout of the overall shape structure.

[0121] For 16 over-flow channels, the sliding complex door can group them to achieve partial penetration and partial non-penetration (blocked by the child door) at a certain gate. For ease of explanation, define the multiple over-flow channels that are simultaneously in the penetration / non-penetration state at a certain gate as M group, N group. According to the principles, structures and drawings of the present application, it can be understood that at the first phase-locked gate, the over-flow channels of the M group are front and rear penetration, while the over-flow channels of the N group are non-penetration (blocked); at the second phase-locked gate, the over-flow channels of the M group are non-penetration (blocked), while the over-flow channels of the N group are front and rear penetration. In this way, at different gates, the penetration / non-penetration state of the M group and the N group is alternated according to the reciprocating motion of the sliding complex door, thereby realizing the switching of the valve body to different water flow directions.

[0122] The single valve with 4 over-flow ports in the prior art is subjected to huge pressure at each over-flow port and in the switching process, which is easy to cause valve body failure or even damage due to overpressure. The flow conversion complex valve protected by the present application is a complex valve flow conversion valve composed of four single valves arranged in strict two-dimensional symmetry (central symmetry) according to the 2x2 over-flow ports. Each flow conversion single valve includes two water inlet rooms, two water outlet chambers, a sliding door and its corresponding sliding chamber. From the whole, it can be understood as a complex valve composed of four single valves, including eight water inlet rooms, eight water outlet chambers, a sliding complex door composed of four sliding doors and a whole sliding chamber formed by the fusion of four sliding chambers. 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 water drainage is arranged on the lower layer. Correspondingly, due to the two-dimensional symmetry (central symmetry) of the four single valves in the complex valve flow conversion valve, the arrangement of water inlet, water lifting and water drainage also presents two-dimensional symmetry (central symmetry).

[0123] The motor water pump auxiliary water-lifting commutation is through the water hammer after commutation first, and the inner flow of the water hammer does not generate excess pressure and excess flow rate, thereby protecting the pipeline, eliminating overpressure, achieving the purpose of stable and long-term operation of the commutation valve, the PCCP pressure pipeline and the water hammer water-lifting system, and obtaining longer working life. Of course, in addition to improving the performance of the commutation valve itself, the motor water pump auxiliary water-lifting commutation measures are taken to cooperate with the water pressure (0.1% precision) sensing of the water outlet of the commutation valve water-lifting outlet or the differential pressure sensing of the water-lifting outlet and the drainage outlet (and the target of the equal pressure of the inner flow of the water-lifting outlet of the commutation valve and the inner flow of the drainage outlet), and the energy-saving two-type symmetric water hammer technology (that is, the larger pressure water hammer wave of the water-lifting speed reduction pipeline technology and the smaller pressure water hammer wave of the drainage speed increase pipeline technology, so that the drainage speed increase pressure recovery reflection wave reaches the commutation valve after commutation, creates a commutation window period of the drainage flow without pressure rise of the commutation valve, achieves stable drainage flow rate, and the high-speed water energy loss effect is avoided), so that the commutation quantum electromagnetic coupling locking of the commutation valve of the application only needs to overcome the extremely low load (for example, the water pressure difference below 1 meter of water column) to easily slide and commutate.

[0124] The water hammer pressure of the sliding door type two-dimensional symmetric combined commutation valve of the application is strictly controlled, and the sliding commutation valve has the characteristics of self-balance of static pressure. The commutation valve creates the working position conditions of electromagnetic floating and quantum locking for the commutation valve load. The commutation valve load is self-balance, electromagnetic floating, quantum locking and mechanical wheel track redundant multi-field coupling bearing. Under normal working conditions, the commutation valve load is electromagnetic floating and quantum locking. The commutation valve shuttle weaving operation is non-mechanical bearing, so there is no mechanical friction, thereby ensuring long-term operation. The self-balance of the water hammer static pressure of the sliding commutation valve structure greatly reduces or even completely eliminates the load of the electromagnetic floating and quantum locking commutation valve for overcoming the water hammer load, saves power, and facilitates the linear motor driving according to the water hammer rhythm to slide. In particular, during the water-lifting period of each water hammer, the self-balance bearing water hammer static pressure of the commutation valve structure can reduce the quantum locking output, so as to eliminate the electromagnetic floating output, and realize the minimization of the quantum electromagnetic locking load.

[0125] The arrangement mode of the overcurrent passage of the application cooperates with the sliding commutation valve combined with the sub-door and the overcurrent ring, and can realize the self-balance of the statics water hammer pressure of the sliding commutation valve. The resultant force of the sliding commutation valve is 0, and the moment of the resultant force is 0. In addition, when the cross section of the overcurrent passage and the overcurrent ring is circular, oval, rectangular or square, the statics water pressure of the sliding commutation valve can also be completely self-balanced during the sliding process. At the same time, the commutation valve also creates the sealing working position conditions for the water-lifting and drainage isolation and the pressure internal water sealing in structure, and the sealing technology directly controls the pressure seepage leakage, which can make the system water-lifting efficiency the highest.

[0126] A preferred embodiment of the present application will now be described in detail with reference to the drawings.

[0127] In combination Figure 1The commutation structure of the preferred embodiment shown includes a sliding cavity 110, a sliding complex door 120, a quantum locking assembly 130, a linear motor 140 and an electromagnetic locking assembly 150.

[0128] In the embodiment, the sliding cavity 110 includes 16 groups of flow passage assemblies 111 for forming 16 flow passages, each group of flow passage assemblies 111 has a gap in the cross-sectional direction, and the gaps of all the flow passage assemblies 111 are mutually penetrated in the same plane. The 16 flow passages are arranged in a reasonable manner, combined with the Figure 1 and Figure 3 The arrangement shown is that the 16 flow passages are arranged as 2 first flow columns 1101 and 2 second flow columns 1102, each of the first flow columns 1101 and the second flow columns 1102 includes 4 longitudinally arranged flow passages. The 2 second flow columns 1102 are arranged between the 2 first flow columns 1101, and an intermediate empty column 1103 is arranged between the 2 second flow columns 1102, and the first empty column 1104 and the second empty column 1105 are arranged on the opposite outer sides of the 2 first flow columns 1101.

[0129] The flow passage assembly 111 is configured as a ring-shaped columnar structure, which has a gap in the cross-sectional direction, that is, the gap separates the flow passage assembly 111 in the ring-shaped columnar structure into two parts located on the front side and the rear side respectively, and the end faces on the front side and the rear side are connected with the shell of the sliding cavity and realize the internal penetration of the flow passages.

[0130] The flow passage assembly 111 can be configured as a structure as shown in Figures 1 to 3 , Figure 6 The outer wall is circular and the inner wall is elliptical, and the major axis of the ellipse is arranged horizontally, so the wall thickness in the up-down direction of the flow passage assembly 111 is relatively thick, obviously thicker than the wall thickness in the left-right direction, such a shape not only thickens the wall thickness of the passage assembly and can withstand greater water flow impact, but also can provide accommodation positions for the dewars 131 arranged along the up-down direction.

[0131] Specifically, mounting grooves are pre-set at the positions of the outer wall where the wall thickness in the up-down direction is relatively thick, and the dewars 131 are embedded in the mounting grooves, so that the dewars 131 are embedded in the up-down wall of the flow passage assembly 111 on the front and rear sides of the gap, the flow passages are located between the two dewars 131 in the up-down direction, and the two dewars 131 of the up-down wall of the flow passage assembly 111 on the front and rear sides of the gap are arranged symmetrically based on the cross-sectional direction, and similarly, the two dewars 131 of the up-down wall on the front and rear sides are also arranged symmetrically based on the cross-sectional direction.

[0132] In the embodiment, as shown in Figure 7As shown, the first flow column 1101 and the second flow column 1102 correspond to the water lifting function and the water draining function respectively.

[0133] In the embodiment, the sliding complex door 120 is designed as a two-dimensional symmetrical static self-balancing 12-door structure as a whole, and is accommodated in the gap of the flow channel assembly 111. Specifically, as shown in Figure 4 As shown, the sliding complex door 120 includes 12 doors 121 and 12 flow rings 122 arranged in a reasonable manner. In combination with Figure 1 and Figure 3 As shown, the doors 121 and the flow rings 122 of the sliding complex door 120 are arranged in four horizontal rows, each of which includes three doors and three flow rings, and the three doors and the three flow rings are arranged in an alternating manner. In order to realize the switching function, the top and bottom horizontal rows are the first horizontal rows 1201 arranged in the same manner, and the two second horizontal rows 1202 arranged in the same manner are arranged between the two first horizontal rows 1201. From Figure 4 It can be clearly seen that, from the left side of the first horizontal row 1201, the doors and the flow rings are sequentially and alternately arranged from left to right, and the right side ends with a flow ring; from the left side of the second horizontal row 1202, the flow rings and the doors are sequentially and alternately arranged from left to right, and the right side ends with a door. Therefore, the doors 121 and the flow rings 122 in the first horizontal row 1201 and the doors 121 and the flow rings 122 in the second horizontal row 1202 are arranged in an alternating manner, and such a design can realize reasonable switching between the flow channels with water lifting or water draining functions during sliding.

[0134] In the embodiment, the flow ring 122 is configured as an elliptical ring with the same shape as the inner wall of the flow channel assembly 111, the horizontal long axis is parallel to the horizontal direction, the vertical short axis is parallel to the vertical direction, and the length of the short axis is slightly smaller than the height of the door 121. Preferably, the flow ring 122 is connected to the upper and lower double-sided permanent magnet rails 132, the left and right doors 121 or the longitudinal spokes 124 through the connecting elements 1221.

[0135] In the embodiment, the sliding complex door 120 further includes five horizontal beams 123 with fused rails, which are components of the frame structure connecting the doors 121 and the flow rings 122, and specifically as shown in Figure 4As shown in the figure, three of the beams 123 are arranged as middle beams 1233, which are respectively arranged between two first horizontal rows 1201 and two second horizontal rows 1202, so as to connect and fix the sub-door 121 and the flow ring 122. The other two beams 123 are arranged as top beams 1231 and bottom beams 1232, which are respectively arranged on the top of the upper first horizontal row 1201 and the bottom of the lower second horizontal row 1202, i.e. as the outer frame of the top and bottom of the sliding complex door.

[0136] As shown in the figure, Figure 4 and Figure 5A The double-sided permanent magnet track 132 is arranged on the sliding complex door 120, and the double-sided permanent magnet track 132 is arranged on the upper and lower sides of the sub-door 121 and the flow ring 122 in the same horizontal row. When the sliding complex door 120 is installed in the gap of the sliding cavity 110, the position of the double-sided permanent magnet track 132 is located between the front and rear two Dewars 131 corresponding to the group of Dewars.

[0137] In the embodiment, the beam 123 can be configured as a hollow plate structure with a certain height, which can meet the rigidity requirement of bearing and the requirement of water flow in the sliding cavity. The double-sided permanent magnet track 132 is connected to the beam 123, and the sub-door 121 and the flow ring 122 are fixed between the two double-sided permanent magnet tracks 132, so as to form the overall structure of the sliding complex door. According to Figure 1 and Figure 4 The plurality of beams 123 are uniformly distributed, and the extension mode of the beam 123 is along the transverse direction and the front and rear direction.

[0138] In the embodiment, the sliding complex door 120 further comprises three longitudinally distributed spokes 124, which are also components of the frame structure. One of the spokes 124 is arranged on the leftmost side, one of the spokes 124 is arranged on the rightmost side, and the other spoke 124 is arranged at the middle position of the sliding complex door and longitudinally passes through the four horizontal rows. Each row of the left and right spokes 124 respectively comprises 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 arrangement of the longitudinal spoke 124 can effectively increase the strength of the sliding complex door, and the precision of the planar finish machining and micron finish machining of the sliding complex door in the production and manufacturing process can also ensure the sealing effect of the end face sealing.

[0139] In the embodiment, the slide cavity 110 also 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 slide cavity, and the space between the lower surface of the bottom beam 1232 and the inner wall of the slide cavity. It can be understood that the movers of the upper and lower linear motors are connected to the top beam 1231 and the bottom beam 1232 respectively, so as to realize the driving of the slide complex door 120 to move reciprocatingly in the slide cavity 110 according to the water hammer rhythm, as shown in Figure 1 The upper surface of the top beam 1231 and the lower surface of the bottom beam 1232 correspond to the positions of the first flow column 1101 and the second flow column 1102, and the movers of the linear motors are arranged correspondingly. In this way, the driving force of the slide complex door is balanced as a whole, so as to stably drive the movement of the slide complex door, and the force acting on the slide complex door is balanced from the perspective of the driving force of the motor.

[0140] In the embodiment, the electromagnetic locking assembly 150 includes a U-shaped rail integrated with the cross beam 123. Therefore, it can be understood that there are five U-shaped rails 153 on the front and back sides of the slide complex door 120, and electromagnets 152 are arranged on the inner wall of the slide cavity 110 corresponding to the positions of the U-shaped rails 153. The front and back end faces of the U-shaped rails 153 form notches of U-shaped tracks, which face the front / back side direction.

[0141] In the embodiment, the inner wall of the slide cavity 110 is provided with a groove, and the electromagnets 152 are integrally arranged in the groove. The position of the electromagnets 152 protrudes from the inner wall of the slide cavity 110, but maintains a distance of 5 mm with the U-shaped rails 153, so as to ensure the work without affecting the sliding movement of the slide complex door. The electromagnets 152 are provided with a core 1522 clamped between upper and lower side plates 1521, and a coil (not shown in the figure) is arranged around the core. The horizontal extension length of the coil is slightly smaller than the horizontal length of the inner wall of the slide cavity, and the distance between the upper and lower side plates 1521 is equal to the opening height of the notches of the U-shaped tracks.

[0142] Necessarily, the electromagnets 152 and the U-shaped rails 153 are arranged in a corresponding manner. As can be understood from the foregoing structure, the slide complex door 120 includes five cross beams 123, and each cross beam 123 is provided with a U-shaped rail 153 on the front and back end faces. Each U-shaped rail 153 corresponds to a groove and an electromagnet 152 arranged in the groove. Therefore, it can be understood that the U-shaped rails 153 on the front and back sides are symmetrically arranged with the slide complex door 120 as a reference, and the grooves on the front and back sides, the electromagnets on the front and back sides are also symmetrically arranged. Combined with the structure of the slide complex door 120, the electromagnets 152 on the front and back sides are arranged in a corresponding manner with the U-shaped rails 153 on the front and back sides. Figures 1 to 5BThe two rows of electromagnets 152 correspond to the opening walls of the front and rear U-shaped track slots respectively, and the electromagnetic locking assembly 150 is a bilateral symmetrical electromagnetic locking structure, which is beneficial to the stability and correction of the relative position between the sliding complex door 120 and the sliding cavity 110 in the moving state / locked state, and can withstand the impact of water flow to a certain extent.

[0143] As shown in the figure, the U-shaped track slot is provided with a fixed rail 151 made of non-magnetic material. The side of the fixed rail 151 facing the bottom of the U-shaped slot is embedded with a lubricating guide shoe 1511.

[0144] It can be understood that the shape and size of the end surface of the flow passage assembly 111 of the sliding cavity 110 match those of the flow ring 122 of the sliding complex door 120. Specifically, the flow ring 122 has an annular structure with an elliptical cross section, and the flow passage assembly 111 has an annular columnar structure with an elliptical cross section. Therefore, when the sliding complex door 120 slides to any locking door position, the flow ring 122 and the annular end surface of the flow passage assembly 111 just coincide, so that the flow passage is through.

[0145] It can be understood that the shape and size of the end surface of the flow passage assembly 111 of the sliding cavity 110 match those of the sub-door 121 of the sliding complex door 120. Specifically, Figure 1 and Figure 4 As shown in the figure, the cross-sectional shape of the sub-door 121 is rectangular, with the horizontal side being the long side and the vertical side being the short side. The short side is slightly larger than the length of the major axis of the cross section of the flow passage assembly. When the sliding complex door 120 slides to any locking door position, part of the flow passage is in a non-through state, and the size of the sub-door 121 can cover the elliptical annular end surface of the flow passage assembly 111 to block the water flow through the flow passage.

[0146] On the basis of this structure, when the sliding complex door 120 slides to any locking door position, part of the flow passage is in a through state, and the flow ring 122 and the end surface of the corresponding flow passage assembly 111 can just coincide, and the end surface sealing structure can maximize the water flow and sealing performance, realizing the "opening" of the flow passage. At the same time, the sub-door 121 can completely block the end surface of the corresponding flow passage assembly 111, thereby blocking the water flow through the flow passage and realizing the "closing" of the flow passage. The reciprocating movement of the sliding complex door 120 can alternately realize the "opening" and "closing" of each flow passage, thereby realizing the commutation function of the commutation complex valve.

[0147] In the embodiment, the sliding cavity 110 is formed by a sealing shell 112, the sliding complex door 120, the flow passage assembly 111, the Dewar 131, the electromagnet 152 and the linear motor 140 are all contained in the sliding cavity 110 in the shell 112, and the overall sealing of the electromagnetic conversion structure can be realized. Since the flow passage needs to pass through the front and back directions to make the water flow through, the end of the flow passage assembly 111 is formed as a through hole on the shell 112.

[0148] The application also provides a conversion complex valve of the conversion structure using the quantum electromagnetic suspension coupling locking technology. Figure 6 As shown in the figure, the conversion complex valve includes a water inlet part 200, a water outlet part 300 and a conversion part 100, the conversion part 100 is arranged between the water inlet part 200 and the water outlet part 300, and the conversion part 100 includes the conversion structure as described above.

[0149] As shown in the figures, Figure 6 , Figures 8 to 10 In the embodiment, the water inlet part 200 includes a plurality of water inlet rooms 210, each of the water inlet rooms 210 includes one water inlet port 211 and two transversely arranged water outlet ports 212, and the two transversely arranged water outlet ports 212 are communicated with one flow passage in each of the first flow passage column 1101 and the second flow passage column 1102 in the sliding cavity 110 of the conversion structure.

[0150] As shown in the figures, Figure 6 , Figures 11 to 13 In the embodiment, the water outlet part 300 includes a plurality of water outlet chambers 310, each of the water outlet chambers 310 includes one water outlet port 312 and two longitudinally arranged water inlet ports 311, and the two longitudinally arranged water inlet ports 311 are communicated with two adjacent flow passages in one column of the sliding cavity 110.

[0151] The conversion complex valve of the application is applied to a water delivery and drainage system of double PCCP pipes, which includes an upstream first PCCP pipe and a second PCCP pipe, a downstream water lifting pipe and a downstream drainage pipe. The water outlet ends of the first PCCP pipe and the second PCCP pipe are communicated with the water inlet part 200 of the conversion complex valve, and the water inlet ends of the downstream water lifting pipe and the downstream drainage pipe are communicated with the water outlet part 300 of the conversion complex valve.

[0152] In the embodiment, half of the water inlet ports in the water inlet part 200 of the conversion complex valve are communicated with the first PCCP pipe, and the other half of the water inlet ports are communicated with the second PCCP pipe.

[0153] Specifically as shown in the figures, Figures 8 to 10The water inlet part 200 includes 8 water inlet rooms 210, which are arranged in four rows in the transverse direction. The water inlets 211 of the 8 water inlet rooms 210 are also arranged in four rows in the transverse direction. The 4 water inlets in the top and bottom rows are connected to the first PCCP pipe, and the 4 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 4 longitudinal rows of the 16 flow channels.

[0154] In this embodiment, half of the water outlets in the water outlet part 300 of the valve are connected to the downstream water lifting pipe, and the other half are connected to the downstream drainage pipe.

[0155] Specifically combined Figure 11 and Figure 13 The water outlet part 300 includes 8 water outlet rooms 310, which are arranged in four columns in the longitudinal direction. The water outlets 312 of the 8 water outlet rooms 310 are also arranged in four columns in the longitudinal direction. The 4 water outlets on the left and right sides, which correspond to the first flow longitudinal column 1101, are connected to the downstream water lifting pipe as water lifting gates. The 4 water outlets in the middle two columns, which correspond to the second flow longitudinal column 1102, are connected to the downstream drainage pipe as drainage gates. The water inlets 311 of the 8 water outlet rooms 310 correspond to the 4 longitudinal rows of the 16 flow channels.

[0156] Due to the above-mentioned flow reversing structure, which further includes the middle empty column and the first and second empty columns on both sides, the width range of the water inlet room and the water outlet room can cover the width of the empty column, and can have a certain water flow buffering function and a reasonable overall shape structure.

[0157] The above-mentioned flow reversing structure and the flow reversing valve structure shown in the drawings are described from the structural point of view for the preferred embodiments. In order to be easier to understand, the distribution mode of the flow channel is explained from the functional point of view as follows.

[0158] Figures 14 to 15 It is a plan view of the distribution of the flow channel 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 process description, and is used to assist understanding.

[0159] In terms of functions, each overcurrent passage a is defined as a water lifting inlet of the first PCCP pipe, each overcurrent passage b is defined as a water discharge outlet of the first PCCP pipe, each overcurrent passage c is defined as a water lifting inlet of the second PCCP pipe, and each overcurrent passage d is defined as a water discharge outlet of the second PCCP pipe. The "water lifting inlet" function herein is a water lifting function realized based on the first overcurrent column 1101 in the embodiment in communication with the downstream water lifting pipe, and the "water discharge outlet" function is a water discharge function realized based on the second overcurrent column 1102 in the embodiment in communication with the downstream water discharge pipe.

[0160] In combination with the drawings, the overcurrent passage 1a, the overcurrent passage 1b, the overcurrent passage 1c, and the overcurrent passage 1d form a small-scale overcurrent combination (or understood as a single valve), for convenience of description, referred to as a first combination. In the first combination, the overcurrent passage 1a on the left side is a water lifting inlet of the first PCCP pipe, the overcurrent passage 1b on the right side is a water discharge outlet of the first PCCP pipe, the overcurrent passage 1c below the left side is a water lifting inlet of the second PCCP pipe, and the overcurrent passage 1d below the right side is a water discharge outlet of the second PCCP pipe.

[0161] Similarly, the overcurrent passage 2a, the overcurrent passage 2b, the overcurrent passage 2c, and the overcurrent passage 2d also form a small-scale overcurrent combination, referred to as a second combination, which is located on the right side of the first combination. The overcurrent passage 3a, the overcurrent passage 3b, the overcurrent passage 3c, and the overcurrent passage 3d form a third combination, which is located on the lower side of the first combination. The overcurrent passage 4a, the overcurrent passage 4b, the overcurrent passage 4c, and the overcurrent 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 inlet, 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, the third combination and the fourth combination are symmetrical with respect to the transverse direction, or the first combination to the fourth combination is arranged to be centrally symmetrical with the center point of the middle empty column as the reference center. In this way, it can correspond to the "four single valves arranged in a 2x2 overcurrent port strictly two-dimensional symmetrical (central symmetrical) combination of complex valve overcurrent valve" in the foregoing principle.

[0162] It can be understood that the overcurrent passages 1a, 1c, 3c, and 3a are located in the first longitudinal column 1101 on the left side of the sliding cavity 110, the overcurrent passages 1b, 1d, 3d, and 3b are located in the second overcurrent longitudinal column 1102 on the left side of the sliding cavity 110, the overcurrent passages 2a, 2c, 4c, and 4a are located in the first longitudinal column 1101 on the right side of the sliding cavity 110, and the overcurrent passages 2b, 2d, 4d, and 4b are located in the second overcurrent longitudinal column 1102 on the right side of the sliding cavity 110.

[0163] The above-mentioned arrangement of the flow passage, combined with the sliding double gate containing the sub-gate and the flow ring, can achieve self-balancing of the static water hammer pressure of the sliding double gate. That is, the sliding double gate has the characteristics of zero resultant force and zero resultant torque. When the inner wall of the flow outlet is elliptical, the static water pressure during the sliding process of the combined gate is also completely self-balancing. That is, the flow dynamic pressure of the sliding double gate is balanced by magnetic levitation.

[0164] During operation, when the sliding gate 120 is located as follows: Figure 14 When the first phase is locked at the gate position, it can be seen that the sub-gate is blocked at 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 and connected with the flow ring to allow water flow. Additionally, the sub-gate... The door and the flow ring are located in the middle empty column 1103 and the second empty column 1105 on the right. Therefore, the first PCCP pipe can lift water to the downstream water lifting 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 Dewar and double-sided permanent magnet rails corresponding to each other perform quantum locking on the sliding double door. At the same time, the energized electromagnet and the rails achieve double-sided offset correction of the sliding double door through electromagnetic levitation induction.

[0165] According to the water hammer rhythm requirements, the sliding double door 120, driven by the linear motor 140, moves from the first phase locked door position to the left. Figure 15 The position of the second phase locking gate shown indicates that the sub-gate is blocked at the gate positions of 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. Simultaneously, 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 and connected with the flow ring to allow water flow, and additionally... The sub-gate and the overcurrent ring are located in the middle empty column 1103 and the first empty column 1104 on the left. Therefore, the first PCCP pipe can lift water to the downstream water lifting pipe through the overcurrent channels 1c, 3c, 2c, and 4c, and drain water to the downstream drain pipe through the overcurrent channels 1b, 3b, 2b, and 4b. At this time, the Dewar and double-sided permanent magnet rails corresponding to each other perform quantum locking on the sliding double gate. At the same time, the energized electromagnet and the rails achieve double-sided offset correction of the sliding double gate through electromagnetic levitation 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 complex door 120 to reciprocate in the sliding chamber 110, and the quantum locking assembly and the electromagnetic locking assembly lock the sliding complex door at the first phase locking door position or the second phase locking door position in the reciprocating process, so that the sub-door and the flow ring of the sliding complex door can be respectively coincided with the corresponding flow channel assembly 111. In the first phase locking door position, part of the flow channel is through in front and back, and the other part of the flow channel is blocked by the sub-door. When switched to the second phase locking door position, the through and blocked states of the flow channel are exchanged with each other, so as to realize the switching of the water lifting and drainage stroke in the valve.

[0167] The electromagnetic commutation structure and the electromagnetic commutation complex valve according to the present application are only illustrated in detail by way of example, and the examples are only used to illustrate the principles and implementation modes of the present application, but not to limit the present application. Various modifications and improvements can be made by those skilled in the art without departing from the spirit and scope of the present application. Therefore, all equivalent technical solutions shall belong to the scope of the present application and be limited by the claims of the present application.
