Description

Technical Field

[0001] This utility model relates to the field of electromagnetic hydraulic valve technology, and more specifically, to an integrated electromagnetic hydraulic valve core with a spiral guide groove. Background Technology

[0002] An electromagnetic hydraulic valve is a type of valve that combines electromagnetic control technology with hydraulic control technology. It is used to control the flow direction, pressure, and flow rate of oil in a hydraulic system. An integrated electromagnetic hydraulic valve core refers to a valve core assembly that integrates the electromagnetic control part and the hydraulic valve core part into a single structure. When the electromagnet is energized, it generates a magnetic field, attracting the armature to move, which in turn drives the valve core to move within the valve body, changing the flow area between the valve core and the valve seat, thereby controlling the flow state of the oil.

[0003] A search revealed that Chinese Patent CN221221524U discloses a hydraulic valve core. This invention, by incorporating a discharge control device, facilitates the control of the discharge output and seals the discharge port, thereby preventing side leakage of the oil. Multiple discharge holes are located at the upper end of the inlet port. When the valve core moves, it aligns the inlet port with the upper discharge holes, and the alignment determines the discharge volume, thus achieving the effect of discharge volume control. A storage chamber is located at the lower end of the inlet port, through which the oil is transferred and converted, thus achieving the effect of hydraulic valve control. Sealing rings are distributed on one side of the inlet port, isolating each inlet port and preventing side leakage during oil transmission. Overall, this invention achieves the effect of controlling the discharge volume of the oil.

[0004] When the valve core is in use, the valve core body moves and drives the movable column. The return spring can achieve the reset effect. However, the two ends of the return spring are respectively connected to one side of the receiving groove and one side of the valve core body, making it inconvenient to disassemble and replace the return spring. When the return spring experiences mechanical fatigue, its reset performance will decrease, thereby affecting the working efficiency and accuracy of the hydraulic valve. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an integrated electromagnetic hydraulic valve core with a spiral guide groove, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated electromagnetic hydraulic valve core with a spiral guide groove, comprising a sealing cavity and a valve core body, wherein the valve core body is located inside the sealing cavity, a plurality of first drain holes are provided on the outer side of the sealing cavity, a plurality of inlet holes are provided on the outer side of the valve core body, and a reset assembly is provided on one side of the valve core body, the reset assembly comprising a receiving cylinder, a first connecting plate, a T-shaped insert rod, a second connecting plate, a reset spring, a lead screw and two bolts, one end of the receiving cylinder being fixedly connected to the first connecting plate, one end of the T-shaped insert rod penetrating the receiving cylinder, and the other end of the T-shaped insert rod being fixedly connected to the second connecting plate, both ends of the reset spring being fixedly connected to the second connecting plate and the first connecting plate respectively, the lead screw being fixedly installed on the other side of the second connecting plate, and the first connecting plate being fixed to the sealing cavity by two bolts.

[0007] Furthermore, a locking block is fixedly connected to the other side of the first connecting plate, and one end of the locking block extends into the interior of the sealing cavity.

[0008] It can be seen that the above technical solution aims to improve the stability between the first connecting plate and the sealing cavity.

[0009] Furthermore, two limiting rods are fixedly connected inside the sealing cavity, and one end of each limiting rod penetrates the valve core body.

[0010] It can be seen that the above technical solution is designed to prevent the valve core body from deflecting when it moves horizontally.

[0011] Furthermore, a spiral guide groove column is fixedly connected to one side of the valve core body, and the spiral guide groove column is threadedly connected to the lead screw.

[0012] Furthermore, a second drain hole is provided on the outer side of the sealing cavity, and the second drain hole is located at the bottom of the reset assembly.

[0013] Furthermore, multiple sealing rings are fixedly sleeved on the outer side of the valve core body, and the outer sides of the multiple sealing rings are in contact with the sealing cavity.

[0014] It can be seen that the above technical solution aims to improve the sealing performance between the valve core body and the sealing cavity.

[0015] Furthermore, a toggle lever is fixedly connected to the other side of the valve core body.

[0016] It can be seen that the above technical solution is designed to facilitate the horizontal movement of the valve core body.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model uses the valve core body to drive the spiral guide groove column to move horizontally, thereby driving the return spring to stretch. Similarly, the return spring resets the valve core body. By rotating the two bolts in sequence and moving them away from the first connecting plate, and rotating the second connecting plate and moving the lead screw away from the spiral guide groove column, the reset assembly can be disassembled and replaced. Similarly, the reset assembly can be installed. The operation is simple and the reset spring can be easily disassembled and replaced.

[0019] 2. In this utility model, the oil enters the valve core body, and the spiral guide groove guides the oil, causing the oil to flow in a spiral shape. This flow method can reduce energy loss, improve system efficiency, reduce vibration and noise caused by unstable oil flow, and ensure more stable system operation. Finally, the oil flows out through the second drain hole, forming a complete flow channel. At the same time, the sealing ring can improve the sealing between the valve core body and the sealing cavity. The structure is simple and easy to use. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Refer to the instruction manual appendix Figure 1-5 The integrated electromagnetic hydraulic valve core with spiral guide groove in this embodiment includes a sealing cavity 1 and a valve core body 2, with the valve core body 2 located inside the sealing cavity 1. Multiple first drain holes 4 are provided on the outer side of the sealing cavity 1, and multiple inlet holes 7 are provided on the outer side of the valve core body 2. A reset assembly 6 is provided on one side of the valve core body 2. The reset assembly 6 includes a receiving cylinder 601, a first connecting plate 602, a T-shaped insert 603, a second connecting plate 604, a reset spring 605, a lead screw 606, and two bolts 608. One end of the receiving cylinder 601 is connected to the first connecting plate 604. Plate 602 is fixedly connected. One end of T-shaped insert 603 passes through the receiving cylinder 601, and the other end of T-shaped insert 603 is fixedly connected to the second connecting plate 604. The two ends of the return spring 605 are fixedly connected to the second connecting plate 604 and the first connecting plate 602 respectively. The screw 606 is fixedly installed on the other side of the second connecting plate 604. The first connecting plate 602 is fixed to the sealing cavity 1 by two bolts 608. A locking block 607 is fixedly connected to the other side of the first connecting plate 602, and one end of the locking block 607 extends into the interior of the sealing cavity 1.

[0029] Furthermore, two limiting rods 10 are fixedly connected inside the sealing cavity 1, and one end of each limiting rod 10 penetrates the valve core body 2.

[0030] Furthermore, a spiral guide groove column 8 is fixedly connected to one side of the valve core body 2, and the spiral guide groove column 8 is threadedly connected to the lead screw 606. A second drain hole 5 is opened on the outside of the sealing cavity 1, and the second drain hole 5 is located at the bottom of the reset assembly 6. Multiple sealing rings 9 are fixedly sleeved on the outside of the valve core body 2, and the outside of the multiple sealing rings 9 are in contact with the sealing cavity 1. A toggle rod 3 is fixedly connected to the other side of the valve core body 2.

[0031] When the valve core body 2 moves horizontally, the distance between the first drain hole 4 and the inlet hole 7 can be changed, thereby achieving the effect of flow control. The oil enters the valve core body 2, and the spiral guide groove column 8 guides the oil, making the oil flow in a spiral shape. This flow mode can reduce energy loss, improve system efficiency, reduce vibration and noise caused by unstable oil flow, and ensure more stable system operation. Finally, the oil flows out through the second drain hole 5, forming a complete flow channel. At the same time, the sealing ring 9 can improve the sealing between the valve core body 2 and the sealing cavity 1. The structure is simple and easy to use. Meanwhile, the two limit rods 10 can prevent the valve core body 2 from deflecting when it moves horizontally.

[0032] The usage method of this embodiment is as follows:

[0033] In use, when the lever 3 pulls the valve core body 2 horizontally, the valve core body 2 drives the spiral guide groove column 8 to move horizontally, thereby stretching the return spring 605. At the same time, the T-shaped insert 603 moves on the receiving cylinder 601, which can prevent the return spring 605 from deflecting when deformed. Similarly, the return spring 605 resets the valve core body 2. The two bolts 608 are rotated in sequence and moved away from the first connecting plate 602, thereby releasing the fixation between the first connecting plate 602 and the sealing cavity 1. The valve core body 2 is moved horizontally and the first connecting plate 602 is moved away from the inside of the sealing cavity 1. The second connecting plate 604 is rotated and the screw 606 is moved away from the spiral guide groove column 8, so that the reset assembly 6 can be disassembled and replaced. Similarly, the reset assembly 6 can be installed. The operation is simple and convenient for disassembling and replacing the return spring 605. At the same time, the locking block 607 is inserted into the sealing cavity 1, which can improve the stability between the first connecting plate 602 and the sealing cavity 1.
