Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a high-speed motor controlled hydraulic solenoid valve. Background Technique

[0002] A solenoid valve is an industrial device controlled by electricity. It is a basic automation component for controlling fluids and belongs to an actuator, not limited to hydraulic and pneumatic applications. It is used in industrial control systems to adjust parameters such as the direction, flow rate, speed, and others of the medium. The solenoid valve can cooperate with different circuits to achieve the expected control, and both the control accuracy and flexibility can be ensured. There are many types of solenoid valves, and different solenoid valves play roles in different positions of the control system. The most commonly used ones are check valves, safety valves, direction control valves, speed regulating valves, etc. The working principle of the solenoid valve is that there is a sealed cavity inside the solenoid valve, with through holes opened at different positions. Each hole is connected to a different oil pipe. In the middle of the cavity is a piston, and on both sides are two electromagnets. Whichever side the magnet coil is energized, the valve body will be attracted to that side. By controlling the movement of the valve body, different oil discharge holes can be opened or closed.

[0003] Most of the existing solenoid valves are opened by energizing and attracting the sealed electromagnet to open the sealed cavity, and after power-off, the electromagnet is pushed by a spring to seal the cavity again. It is inconvenient when the solenoid valve needs to be opened and closed at shorter intervals, and when the frequency of opening and closing the solenoid valve is relatively high, it is easy to damage the solenoid valve. Therefore, it is necessary to design a high-speed motor controlled hydraulic solenoid valve to solve the above-mentioned problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a high-speed motor controlled hydraulic solenoid valve.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] It includes a valve body and a first fixed shell. On the upper left side of the first fixed shell, there is a motor. On the left side of the first fixed shell, there are a first connecting shaft and a second connecting shaft. One end of the first connecting shaft is provided with a first circular mounting hole, and the other end of the first connecting shaft is provided with a first connecting column. Both ends of the second connecting shaft are provided with second circular mounting holes. The rotating shaft of the motor is fixedly connected to the inside of the first circular mounting hole. The first connecting column is rotatably connected to the inside of one of the second circular mounting holes. On the left side of the first fixed shell, there is a fixedly connected rack. One side of the rack meshes with a gear. In the middle of the left end of the gear, there is a second connecting column. The outside of the second connecting column is rotatably connected to the inside of the other second circular mounting hole. In the middle of the right side of the gear, it is fixedly connected to one end of a moving shaft. The other end of the moving shaft is rotatably connected to a mounting shaft, and the bottom end of the mounting shaft is fixedly connected to a telescopic column;

[0007] With the above technical solution, the rotating shaft of the motor rotates at one end of the first coupling shaft, and the other end of the first coupling shaft drives the second coupling shaft and the gear to reciprocate on the toothed plate, driving the telescopic column to reciprocate up and down inside the valve body, and the dimensions of the first coupling shaft, the second coupling shaft and the toothed plate can be adjusted to increase or decrease the interval of the reciprocating movement of the telescopic column.

[0008] Furthermore, an installation groove is provided in the upper part of the first fixed housing, and the motor is fixedly connected to the inner side of the installation groove;

[0009] With the above technical solution, it is convenient to fixedly install the motor on the first fixed housing and protect the motor at the same time.

[0010] Furthermore, a guide groove is provided in the middle of the lower end on the right side of the first fixed housing, and the outer side of the right end of the moving shaft is slidably connected to the inner side of the guide groove;

[0011] With the above technical solution, when the moving shaft moves up and down following the gear, the moving shaft slides downward inside the guide groove, increasing the connection performance between the gear and the first fixed housing, and guiding the movement of the gear and the moving shaft left and right, increasing the movement stability.

[0012] Furthermore, a slot is provided in the middle of the inner bottom end of the valve body, and the shape of the slot fits the shape of the telescopic column;

[0013] With the above technical solution, when the telescopic column is engaged with the slot, the left and right spaces inside the valve body are in a sealed state, and when the telescopic column is not engaged with the slot, the left and right spaces inside the valve body are in a communicating state, which is convenient for the telescopic column to separate the left and right spaces inside the valve body.

[0014] Furthermore, a mounting platform is provided in the upper part of the valve body;

[0015] With the above technical solution, it is convenient to connect and fix the whole formed by the first fixed housing and the second fixed housing to the valve body.

[0016] Furthermore, a second fixed housing is provided on the outer side of the first fixed housing;

[0017] With the above technical solution, the motor, the first coupling shaft, the second coupling shaft, the toothed plate and the gear are placed inside the first fixed housing and the second fixed housing, and then the first fixed housing and the second fixed housing are connected and fixed to the valve body to protect the internal components from damage.

[0018] The utility model has the following beneficial effects:

[0019] First, it is fixed through the first circular mounting hole provided at one end of the first coupling by the rotating shaft of the motor. The rotating shaft of the motor drives one end of the first coupling to rotate, and the other end of the first coupling rotates along a circular motion trajectory. Then, the first connecting column provided at the other end of the first coupling rotates within the second circular mounting hole provided at one end of the second coupling, and drives one end of the second coupling to rotate along a circular motion trajectory. The other end of the second coupling moves up and down in the horizontal direction. Secondly, the second circular mounting hole provided at the other end of the second coupling rotates on the second connecting column provided on the left side of the gear. The other end of the second coupling pushes the gear to move up and down. The gear meshes and moves on the toothed plate, causing the moving shaft to move up and down within the guiding groove during rotation. Since the moving shaft is rotationally connected to the mounting shaft, it drives the telescopic column to move up and down telescopically. When the telescopic column moves upward, the internal space of the valve body is in a communicating state. When the telescopic column moves downward, it engages with the slot, separating the left and right spaces inside the valve body. At the same time, driven by the motor, the gear reciprocates on the toothed plate, causing the telescopic column to reciprocate up and down. It can open and close the valve body reciprocally in a relatively short interval time, avoiding the risk of damaging the solenoid valve when the electromagnetic adsorption frequency is high. At the same time, the dimensions of the first coupling, the second coupling, and the toothed plate can be adjusted to increase or decrease the interval of the reciprocating movement of the telescopic column.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Referring to Figures 1-4 , an embodiment provided by the present invention includes a valve body 1 and a first fixed housing 2. A motor 4 is provided at the upper left of the first fixed housing 2. A first coupling shaft 5 and a second coupling shaft 7 are provided on the left side of the first fixed housing 2. One end of the first coupling shaft 5 is provided with a first circular mounting hole 6, and the other end of the first coupling shaft 5 is provided with a first connecting column 8. Both ends of the second coupling shaft 7 are provided with second circular mounting holes 9. The rotating shaft of the motor 4 is fixedly connected to the inside of the first circular mounting hole 6. The first connecting column 8 is rotatably connected to the inside of one of the second circular mounting holes 9. The left side of the first fixed housing 2 is fixedly connected with a toothed plate 12. A gear 10 is meshed with one side of the toothed plate 12. The middle of the left end of the gear 10 is provided with a second connecting column 11. The outside of the second connecting column 11 is rotatably connected to the inside of the other second circular mounting hole 9. The middle of the right side of the gear 10 is fixedly connected to one end of a moving shaft 13. The other end of the moving shaft 13 is rotatably connected to a mounting shaft 14. The bottom end of the mounting shaft 14 is fixedly connected with a telescopic column 15.

[0028] An installation groove 3 is provided at the upper part of the first fixed housing 2. The motor 4 is fixedly connected to the inside of the installation groove 3, which is convenient for the fixed installation of the motor 4 on the first fixed housing 2 and at the same time protects the motor 4. A guide groove 17 is provided in the middle of the lower right side of the first fixed housing 2. The outside of the right end of the moving shaft 13 is slidably connected to the inside of the guide groove 17. When the moving shaft 13 moves up and down following the gear 10, the moving shaft 13 slides downward inside the guide groove 17, which increases the connection performance between the gear 10 and the first fixed housing 2 and makes the movement of the gear 10 and the moving shaft 13 have left-right guidance, increasing the movement stability.

[0029] In the middle of the inner bottom end of the valve body 1, there is a slot 16. The shape of the slot 16 fits the shape of the telescopic column 15. When the telescopic column 15 is engaged with the slot 16, the left and right spaces inside the valve body 1 are in a sealed state. When the telescopic column 15 is not engaged with the slot 16, the left and right spaces inside the valve body 1 are in a communicating state, which is convenient for the telescopic column 15 to separate the left and right spaces inside the valve body 1. There is a mounting platform 18 on the upper part of the valve body 1, which is convenient for the overall formed by the first fixed shell 2 and the second fixed shell 19 to be connected and fixed to the valve body 1. The second fixed shell 19 is arranged on the outside of the first fixed shell 2. The motor 4, the first coupling 5, the second coupling 7, the toothed plate 12 and the gear 10 are placed inside it through the first fixed shell 2 and the second fixed shell 19, and then the first fixed shell 2 and the second fixed shell 19 are connected and fixed to the valve body 1 to protect the internal components from damage.

[0030] Working principle: First, the rotating shaft of the motor 4 is fixed in the first circular mounting hole 6 provided at one end of the first coupling 5. The rotating shaft of the motor 4 drives one end of the first coupling 5 to rotate, and the other end of the first coupling 5 rotates along a circular motion trajectory. Then, the first connecting column 8 provided at the other end of the first coupling 5 rotates in the second circular mounting hole 9 provided at one end of the second coupling 7 and drives one end of the second coupling 7 to rotate along a circular motion trajectory, and the other end of the second coupling 7 moves up and down in the horizontal direction. Secondly, the second circular mounting hole 9 provided at the other end of the second coupling 7 rotates on the second connecting column 11 provided on the left side of the gear 10, and the other end of the second coupling 7 pushes the gear 10 to move up and down. The gear 10 meshes and moves on the toothed plate 12, so that the moving shaft 13 moves up and down in the guide groove 17 during rotation. Since the moving shaft 13 is rotationally connected to the mounting shaft 14, the telescopic column 15 is driven to move up and down telescopically. When the telescopic column 15 moves upward, the internal space of the valve body 1 is in a communicating state. When the telescopic column 15 moves downward, it is engaged with the slot 16, and the left and right spaces inside the valve body 1 are separated. At the same time, driven by the motor 4, the gear 10 reciprocates on the toothed plate 12, so that the telescopic column 15 moves up and down reciprocally.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
