The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0016] like Figure 1-2 An electric steering control valve is shown, wherein the valve body 1 comprises an upper vertical tube 2, a horizontal tube 3, a lower vertical tube 4 and an adjusting cavity tube 5 which are connected in sequence, the upper vertical tube 2, the horizontal tube 3, the lower vertical tube 4 and the adjusting cavity tube 5 are arranged in a "cross" shape and are integrated, and two upper and lower spherical adjusting blocks 6 are installed in the middle of the valve body 1, and an adjusting piece is installed on the outer side wall of the adjusting cavity tube 5, the adjusting piece extends to the inside of the adjusting cavity tube 5 and fits with the spherical adjusting block 6, and the adjusting piece is used to adjust the angle of the spherical adjusting block 6 inside the valve body 1 and control the connection direction between the upper vertical tube 2, the horizontal tube 3 and the lower vertical tube 4.

[0017] The two spherical adjustment blocks 6 are respectively attached to the ports of the upper vertical tube 2 and the lower vertical tube 4. A 90° groove 7 is opened on the spherical adjustment block 6, and the groove 7 faces the inner cavity side of the adjustment cavity tube 5. A rotating shaft 8 passes through the middle of the spherical adjustment block 6, and the spherical adjustment block 6 rotates inside the valve body 1 through the rotating shaft 8.

[0018] A water inlet hole 9 penetrating the spherical adjusting block 6 is provided inside the spherical adjusting block 6 , and two ends of the water inlet hole 9 are respectively located on two sides of the spherical adjusting block 6 .

[0019] Based on the above, the spherical adjusting block 6 rotates inside the valve body 1 using the rotating shaft 8. When the spherical adjusting block 6 rotates, the positions of the two ends of the water diversion hole 9 will also change.

[0020] like Figure 1 As shown, when the two ends of the water diversion holes 9 in the two spherical adjustment blocks 6 are respectively located inside the upper vertical pipe 2 and the horizontal pipe 3, and inside the lower pipe and the horizontal pipe 3, the flow direction of the entire valve body 1 is:

[0021] The medium enters from the upper vertical pipe 2 and the lower vertical pipe 4 and flows out from the horizontal pipe 3, or enters from the horizontal pipe 3 and flows out from the upper vertical pipe 2 and the lower vertical pipe 4.

[0022] like Figure 2 As shown, when the two ends of the water diversion holes 9 in the two spherical adjusting blocks 6 are respectively located in the adjusting cavity tube 5 and the lower vertical tube 4, and in the adjusting cavity tube 5 and the upper vertical tube 2, the flow direction of the entire valve body 1 is: the medium enters from the upper vertical tube 2, enters into the adjusting cavity tube 5, and then flows out from the lower vertical tube 4, or flows in the opposite direction.

[0023] A partition plate 10 is installed inside the regulating cavity tube 5 , a return spring 11 is installed on the partition plate 10 , and the other end of the return spring 11 is connected to the inner wall of the slot 7 .

[0024] The adjusting member includes a sealing tube 12 installed on the outer wall of the adjusting cavity 5, a sealing filler 13 is filled in the sealing tube 12, a servo push rod 14 is installed at the end of the sealing tube 12, and the output shaft of the servo push rod 14 passes through the sealing tube 12, the sealing filler 13 and the partition 10 and extends to one side of the spherical adjusting block 6 in the adjusting cavity 5.

[0025] The interior of the regulating cavity 5 is divided by using components such as the partition 10 and the sealing filler 13 to avoid leakage.

[0026] A cushion block 15 is installed at the end of the output shaft of the servo push rod 14 , and the cushion block 15 abuts against the surfaces of the slots 7 of the two spherical adjustment blocks 6 .

[0027] A sealing plate 16 is attached to the outer wall of the two spherical adjusting blocks 6 on the side away from the partition plate 10 , and the sealing plate 16 is located at the edges where the two spherical adjusting blocks 6 are close to each other.

[0028] On the basis of the above, if Figure 1 As shown, the spring pulls the slot 7 of the spherical adjusting block 6, and the pad 15 at the end of the output shaft of the servo push rod 14 abuts against the slot 7, limiting the angle of the spherical adjusting block 6, so that the positions of the two ends of the water diversion hole 9 on the spherical adjusting block 6 are moved to appropriate positions, that is, Figure 1 , one end is located at the horizontal tube 3, and the other end is located inside the upper vertical tube 2 and the lower vertical tube 4. At this time, the upper vertical tube 2 is connected to the inside of the horizontal tube 3, and the lower vertical tube 4 is connected to the inside of the horizontal tube 3;

[0029] like Figure 2 As shown, when steering adjustment is required, the pad 15 at the end of the output shaft of the servo push rod 14 is used to press against the inner wall of the slot 7 and push to the other side, so as to control the movement of the output shaft of the servo push rod 14 to push the spherical adjustment block 6 to turn on the rotating shaft 8, change the position of the two ends of the water diversion hole 9 on the spherical adjustment block 6, and make its two ends move to the inside of the regulating cavity tube 5, the upper vertical tube 2 and the lower vertical tube 4, so as to realize the steering of the flow direction of the medium inside the valve body 1.

[0030] Based on the above, when the spherical adjustment block 6 needs to be reset, the output shaft of the servo push rod 14 is reset, and the spherical adjustment block 6 is rotated and reset on the rotating shaft 8 under the force of the reset spring 11. In this process, the cushion block 15 at the end of the output shaft of the servo push rod 14 limits the rotation of the spherical adjustment block 6 when it is reset, so that the flow state of the valve body 1 is restored.

[0031] When the spherical adjusting blocks 6 are rotating, the sealing plate is attached to the edges of the two spherical adjusting blocks 6 , thereby sealing the gap between the two and separating the cross pipe 3 from other components.

[0032] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
