[0050] The working state of the valve body is explained using hydraulic oil as the medium. The specific working state and principle are as follows:

[0051] 1. When the first electromagnetic coil 6 and the second electromagnetic coil 7 corresponding to the inner flow-dividing sleeve 2 and the outer flow-dividing sleeve 3 are not energized, the inner flow-dividing sleeve 2 and the outer flow-dividing sleeve 3 are in a neutral position (specifically, Figure 1 and Figure 8 As shown, it should be noted that Figure 8 In order to better distinguish the valve body 1, the inner flow dividing sleeve 2 and the outer flow dividing sleeve 3, a certain gap is left between the valve body 1, the inner flow dividing sleeve 2 and the outer flow dividing sleeve 3. Actually, there is no gap between the three. Figure 1 shown, and Figure 8-Figure 19 A certain gap is maintained between the three to facilitate better distinction of the three). At this time, the first connecting nozzle 9 is the oil inlet, the second connecting nozzle is the oil outlet, and the oil outlet A, oil outlet B, oil outlet C and oil outlet D are all connected to the oil inlet, so that the oil pressure of the four diversion ports 13 is the same as that of the oil inlet. This state can keep the oil under the diversion ports 13 at the same pressure. For a hydraulic device with an initial neutral state, this working state of the valve body 1 can make the hydraulic structure in a neutral state;

[0052] 2. When one of the first electromagnetic coil 6 and the second electromagnetic coil 7 is energized, the valve body 1 has the following four working states:

[0053] (1) When the first electromagnetic coil 6 in the inner flow-dividing sleeve 2 is energized, it pushes the inner flow-dividing sleeve 2 to move leftward until it contacts the left end of the inner wall of the valve body 1; while the second electromagnetic coil 7 in the outer flow-dividing sleeve 3 is not energized, and the outer flow-dividing sleeve 3 is still in the neutral position. At this time, the valve body 1 is in Fig. 9 In this state, the second annular recess 202 at the right end of the inner diverter sleeve 2 is blocked. At this time, the oil can only pass through the first annular recess 201 from the oil inlet, and enter the oil diverter port A and the oil diverter port C from the first annular recess 201. Therefore, the oil diverter port A and the oil diverter port C are in a high-pressure oil outlet state, while the oil diverter port B and the oil diverter port D are in a low-pressure oil return state.

[0054] (2) When the first electromagnetic coil 6 in the inner flow-dividing sleeve 2 is energized, the inner flow-dividing sleeve 2 is pulled to the right until it contacts the first electromagnetic coil 6; while the second electromagnetic coil 7 in the outer flow-dividing sleeve 3 is not energized, and the outer flow-dividing sleeve 3 is still in the neutral position. At this time, the valve body 1 is in Fig.10 In the state, oil distribution port B and oil distribution port D are in the high-pressure oil outlet state, while oil distribution port A and oil distribution port C are in the low-pressure oil return state.

[0055] (3) When the second electromagnetic coil 7 in the outer flow divider sleeve 3 is energized, the outer flow divider sleeve 3 is pulled to the left until it contacts the second electromagnetic coil 7; while the first electromagnetic coil 6 in the inner flow divider sleeve 2 is not energized, and the inner flow divider sleeve 2 is still in the neutral position. At this time, the valve body 1 is in Fig.11 In the state, the oil distribution port C and the diverter port D are in the high-pressure oil outlet state, while the oil distribution port A and the diverter port B are in the low-pressure oil return state.

[0056] (4) When the second electromagnetic coil 7 in the outer flow divider sleeve 3 is energized, it pushes the outer flow divider sleeve 3 to move rightward until it contacts the inner side of the valve body nut 8; while the first electromagnetic coil 6 in the inner flow divider sleeve 2 is not energized, and the inner flow divider sleeve 2 is still in the neutral position. At this time, the valve body 1 is in Fig.12 In the state, the oil distribution port A and the distribution port B are in the high-pressure oil outlet state, while the oil distribution port C and the distribution port D are in the low-pressure oil return state.

[0057] 3. When the first electromagnetic coil 6 and the second electromagnetic coil 7 are energized at the same time, and the inner flow dividing sleeve 2 and the outer flow dividing sleeve 3 are pushed or pulled to move to the limit position, the valve body 1 has the following three working states different from the above states:

[0058] (1) When the first electromagnetic coil 6 and the second electromagnetic coil 7 are energized, the inner flow divider sleeve 2 and the outer flow divider sleeve 3 move to the left at the same time to the contact limit. At this time, the valve body 1 is in Fig.13 In the state, oil outlet A, oil outlet C and oil outlet D are in the high-pressure oil outlet state, while oil outlet B is in the low-pressure oil return state.

[0059] (2) When the first electromagnetic coil 6 and the second electromagnetic coil 7 are energized, the inner flow divider sleeve 2 is pushed to the left to the contact limit position, and the outer flow divider sleeve 3 is pushed to the right to the contact limit position. At this time, the valve body 1 is in Fig.14 In the state, oil distribution port B and oil distribution port D are in the high-pressure oil outlet state, while oil distribution port A and oil distribution port C are in the low-pressure oil return state.

[0060] (3) When the first electromagnetic coil 6 and the second electromagnetic coil 7 are energized, the inner flow divider sleeve 2 and the outer flow divider sleeve 3 move to the right at the same time until they contact the limit position. At this time, the valve body 1 is in Fig.15In the state, oil outlet A, oil outlet B and oil outlet D are in the high-pressure oil outlet state, while oil outlet C is in the low-pressure oil return state.

[0061] 4. When you are a general Figure 1 The first connecting nozzle 9 is transformed into an oil outlet, and the second connecting nozzle 10 is transformed into an oil inlet. The valve body 1 has the following three working states different from the above states:

[0062] (1) When the first electromagnetic coil 6 and the second electromagnetic coil 7 are not energized, the inner flow divider sleeve 2 and the outer flow divider sleeve 3 remain in a neutral position. At this time, the valve body 1 is in Fig.16 In this state, oil distribution ports A, B, C and D are all in low-pressure oil return state.

[0063] (2) When the first electromagnetic coil 6 and the second electromagnetic coil 7 are energized, the inner flow divider sleeve 2 and the outer flow divider sleeve 3 move to the left at the same time until they contact the limit position. At this time, the valve body 1 is in Fig.17 In the state, the oil distribution port B is in the high-pressure oil outlet state, while the oil distribution ports A, C and D are all in the low-pressure oil return state.

[0064] (3) When the first electromagnetic coil 6 and the second electromagnetic coil 7 are energized, the inner flow divider sleeve 2 and the outer flow divider sleeve 3 move to the right at the same time until they contact the limit position. At this time, the valve body 1 is in Fig.18 In the state, the oil distribution port C is in a high-pressure oil outlet state, while the oil distribution ports A, B and D are all in a low-pressure oil return state.

[0065] In summary, through the conversion of the oil inlet and outlet of the first connecting nozzle 9 and the second connecting nozzle 10 and the opening and closing coordination of the first electromagnetic coil 6 and the second electromagnetic coil 7, the valve body 1 can have the above 11 working states.

[0066] In particular, if one of the diverter port A, diverter port B, diverter port C, and diverter port D is used as the oil inlet, and the other channels are diverter ports, the valve body 1 will have more working states.

[0067] In particular, if the diversion ports A, B, C and D are blocked with sealing nuts, the valve body 1 can generate more working states.

[0068] Therefore, the structures of the inner flow-dividing sleeve 2, the outer flow-dividing sleeve 3 and the valve body 1 in the present invention embody strong precision and ingenuity in configuring the connection relationship of the pore channels.

[0069] Moreover, the diverter sleeve 2, the outer diverter sleeve 3 and the valve body 1 structure are not randomly arranged in the process of configuring the through hole 16, the first connecting hole 14, the second connecting hole 15 and the diverter port A, the diverter port B, the diverter port C, the diverter port D and other structures. In order to achieve the above-mentioned different working states, and the opening designs under different working states interfere with each other, therefore, the applicant needs to consider the optimal solution that can simultaneously satisfy the coordination of each hole position, which requires complex calculations and comparisons, and the present application also excludes many redundant opening schemes that cannot produce ideal working states, in order to finally obtain the above-mentioned solution.

[0070] In addition, according to the above working state and principle, the present invention also provides an aircraft horizontal tail operating system using the above six-channel fluid medium control valve, and the specific application of the valve body 1 in the present invention is explained by the aircraft horizontal tail operation. The operating system specifically includes a fluid medium control valve and two horizontal tails 17, and also includes an actuating cylinder 18 for controlling the two horizontal tails 17 and a control rod 19 for controlling the first electromagnetic coil 6 and the second electromagnetic coil 7 inside the valve body 1. For details, please refer to Fig.19 :

[0071] 1. The control stick 19 is not operated, the valve body 1 is in the neutral position, the horizontal tail 17 remains horizontal, and the aircraft maintains level flight;

[0072] 2. Pull the steering rod 19 backwards, the valve body 1 is in Fig. 9 In the middle state, the left and right actuating cylinders 18 extend simultaneously, the front end of the horizontal tail 17 deflects downward, and the aircraft climbs;

[0073] 3. Push the steering rod 19 forward, the valve body 1 is in Fig.10 In the middle state, the left and right actuating cylinders 18 are retracted simultaneously, the front end of the horizontal tail 17 is deflected upward, and the aircraft descends;

[0074] 4. Press the steering rod 19 to the right, and the valve body 1 is in Fig.11 In the state of the left actuating cylinder 18 extending, the right actuating cylinder 18 retracting, the front end of the left horizontal tail 17 deflecting downward, the front end of the right horizontal tail 17 deflecting upward, the aircraft rolling clockwise along the heading;

[0075] 5. Press the steering rod 19 to the left, and the valve body 1 is in Fig.12 In the state, the left actuating cylinder 18 is retracted, the right actuating cylinder 18 is extended, the front end of the left horizontal tail 17 is deflected upward, the front end of the right horizontal tail 17 is deflected downward, and the aircraft rolls counterclockwise along the heading.

[0076] In summary, the present invention has the advantage of lightweight structure and can integrate oil inlet, oil return and multi-channel oil distribution, making the overall functionality of the valve body 1 stronger. For example, the current aircraft needs at least two hydraulic servos to control the horizontal tail, respectively, while the present invention can achieve this function with only one valve body 1, which is conducive to lightweight design. In addition, it also has similar effects on hydraulic components in other hydraulic systems.

[0077] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
