Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve block technology, and in particular to modular hydraulic valve blocks. Background Technology

[0002] Hydraulic valve blocks are crucial components in hydraulic environments used to control and regulate parameters such as fluid flow direction, flow rate, and pressure. Typically made of metal, hydraulic valve blocks contain multiple channels and cavities. Through the action of valves, valve cores, and other control elements, they control the flow path and flow rate of the fluid to meet the needs of different operating conditions.

[0003] The hydraulic valve block is a core component in a hydraulic environment, mainly composed of an inlet, an outlet, a control valve body, a valve core, channels, adjusting components, and seals. The hydraulic valve block controls the direction, pressure, and flow rate of the hydraulic fluid by moving the valve core within the valve body. After the fluid enters the valve block, the control valve adjusts the flow path and parameters according to requirements, thereby achieving precise control and regulation of the hydraulic fluid and ensuring the safe, stable, and efficient operation of the hydraulic valve block.

[0004] In existing technologies, in complex and ever-changing working environments, different working scenarios have different requirements for the flow and pressure parameters of hydraulic valve blocks. However, since some hydraulic valve blocks are difficult to splice and combine, it is impossible to flexibly adjust the structure and function, which greatly limits the adaptability to different working conditions. Therefore, modular hydraulic valve blocks are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular hydraulic valve block, which aims to improve the problem that some hydraulic valve blocks in the prior art cannot be modularly assembled, resulting in poor adaptability to working conditions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular hydraulic valve block includes a hydraulic valve body, with an external splicing mechanism and an internal pressure relief mechanism.

[0008] The splicing mechanism includes a trapezoidal block, the trapezoidal block being fixedly connected to the outside of one side of the hydraulic valve body, and a trapezoidal groove being provided on the other side of the hydraulic valve body. The trapezoidal block is slidably connected to the inside of the trapezoidal groove. A fixing plate is fixedly connected to one side of the top of the hydraulic valve body, i.e., the side near the trapezoidal groove. A mounting block is fixedly connected to the other side of the top of the hydraulic valve body. A pull plate is slidably connected to the top inside of the mounting block. An elastic component is provided inside the mounting block.

[0009] As a further description of the above technical solution:

[0010] The pressure relief mechanism includes a first fixed ring, which is externally fixedly connected to the inside of the hydraulic valve body. A second fixed ring is fixedly connected to the inside of the hydraulic valve body. A second spring is fixedly connected to the outside of the second fixed ring. A circular plate is fixedly connected to the other end of the second spring. A locking component is slidably connected inside the circular plate.

[0011] As a further description of the above technical solution:

[0012] The elastic component includes a round rod, the outside of which is slidably connected to the inside of the mounting block, one end of which is slidably connected to the inside of the fixing plate, a connecting block fixedly connected to the outside of the round rod, a spring fixedly connected to the outside of the connecting block, the other end of the spring fixedly connected to the inside of the mounting block, and the bottom of the pull plate fixedly connected to the top of the connecting block.

[0013] As a further description of the above technical solution:

[0014] The locking assembly includes a limiting strip, the outer side of which is slidably connected to the inside of the circular plate, and the outer side of which is slidably connected to the inside of the hydraulic valve body;

[0015] As a further description of the above technical solution:

[0016] The hydraulic valve body has a main pipe inside and a branch pipe inside, and the main pipe and the branch pipe are interconnected.

[0017] As a further description of the above technical solution:

[0018] The hydraulic valve body has a threaded hole on its inner top side, and a bolt is threaded into the inner thread of the threaded hole;

[0019] As a further description of the above technical solution:

[0020] The top of the branch pipe is provided with a mounting plate, and the external thread of the bolt is connected to the inside of the mounting plate;

[0021] As a further description of the above technical solution:

[0022] A valve body is fixedly connected inside the mounting plate, and the bottom of the valve body is slidably connected inside the branch pipe.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the operator pulls the pull plate, which drives the connecting block to overcome the spring force and move the round rod. After the trapezoidal block slides into the trapezoidal groove for initial positioning, the pull plate is released and the round rod can be inserted into the fixing plate, realizing the precise splicing and positioning of multiple hydraulic valve bodies, enhancing the overall stability, and facilitating the modular combination of hydraulic valve blocks to meet the needs of different working conditions for hydraulic valve blocks.

[0025] 2. In this utility model, under normal conditions, the second spring keeps the circular plate in contact with the first ring to prevent leakage. When the pressure in the main pipeline is too high, the limit strip is pulled open to release the restriction on the circular plate. The pressure pushes the circular plate to compress the second spring. The movement of the circular plate can be controlled by the limit strip, thereby realizing pressure relief as needed. This can effectively protect the hydraulic valve block, prevent damage to components due to excessive pressure, and ensure the stable and safe operation of the hydraulic valve block.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 One embodiment of this utility model is a modular hydraulic valve block, including a hydraulic valve body 1. The hydraulic valve body 1 has good pressure resistance and wear resistance and can withstand high pressure environment. The hydraulic valve body 1 has a regular block shape and the surface is finely processed to ensure the flatness and smoothness of the mounting surface. The hydraulic valve body 1 is provided with a splicing mechanism on the outside and a pressure relief mechanism on the inside.

[0035] The splicing mechanism includes a trapezoidal block 2, which can be precisely matched with a trapezoidal groove 3. The trapezoidal block 2 is externally fixedly connected to one side of the hydraulic valve body 1. The other side of the hydraulic valve body 1 is provided with a trapezoidal groove 3. When multiple hydraulic valve bodies 1 are spliced, the trapezoidal block 2 can smoothly slide into the trapezoidal groove 3 to achieve initial positioning and connection. The trapezoidal block 2 is externally slidably connected to the inside of the trapezoidal groove 3. A fixing plate 4 is fixedly connected to the top side of the hydraulic valve body 1, that is, the side close to the trapezoidal groove 3. The fixing plate 4 provides additional structural support for the spliced ​​hydraulic valve blocks and, in conjunction with the elastic component, enhances the overall stability. An installation block 5 is fixedly connected to the top side of the hydraulic valve body 1. The installation block 5 is used to accommodate the elastic component and provide guidance for the pull plate 9. The pull plate 9 is slidably connected to the top side of the installation block 5. The pull plate 9 can be easily pulled by the operator. The installation block 5 is provided with an elastic component inside.

[0036] The elastic component includes a round rod 6, which slides into the fixed plate 4 under the action of a spring 8, serving as a limiting element. The outside of the round rod 6 is slidably connected to the inside of the mounting block 5, and one end of the round rod 6 is slidably connected to the inside of the fixed plate 4. A connecting block 7 is fixedly connected to the outside of the round rod 6, which provides a mounting base for the spring 8. The spring 8 provides an outward elastic force to the connecting block 7, allowing the round rod 6 to be inserted into the inside of the fixed plate 4. The other end of the spring 8 is fixedly connected to the inside of the mounting block 5, and the bottom of the pull plate 9 is fixedly connected to the top of the connecting block 7.

[0037] Reference Figure 4 and Figure 5The pressure relief mechanism includes a fixed ring 10, which is used to cooperate with a circular plate 13 to block the passage. The fixed ring 10 is externally fixedly connected to the inside of the hydraulic valve body 1. A fixed ring 2 11 is fixedly connected inside the hydraulic valve body 1. The main function of the fixed ring 2 11 is to provide a mounting base for the spring 2 12. The fixed ring 2 11 is externally fixedly connected to the spring 2 12. The spring 2 12 is in a compressed state, providing a pressure to the circular plate 13 in the direction of the main pipe 15, so that the circular plate 13 fits tightly against the outside of the fixed ring 10 to prevent hydraulic oil leakage. When the internal pressure of the main pipe 15 is too high, the circular plate 13 moves, and the spring 2 12 is further compressed, thereby achieving pressure relief. The other end of the spring 2 12 is fixedly connected to the circular plate 13. The circular plate 13 has a groove inside, which is used to accommodate the locking component. The locking component is slidably connected inside the circular plate 13.

[0038] The locking assembly includes a limit bar 14. The main function of the limit bar 14 is to restrict the movement of the circular plate 13. Only when the limit bar 14 is pulled open and the circular plate 13 is freed from the restriction of the limit bar 14 can it move, thereby realizing the control of pressure relief. The external sliding connection of the limit bar 14 is to the inside of the circular plate 13, and the external sliding connection of the limit bar 14 is to the inside of the hydraulic valve body 1.

[0039] Reference Figure 1 , Figure 2 and Figure 4 The hydraulic valve body 1 has a main pipe 15 inside, and the main pipe 15 and the branch pipe 16 are channels for hydraulic oil transmission. The main pipe 15 and the branch pipe 16 are interconnected. The top side of the hydraulic valve body 1 has a threaded hole 17. The thread of the threaded hole 17 is designed according to the size of the bolt 18 to ensure a good threaded connection between the threaded hole 17 and the bolt 18. The bolt 18 is connected to the threaded hole 17. The bolt 18 is connected to the threaded hole 17 to firmly fix the mounting plate 19 and the valve body 20 to the hydraulic valve body 1, ensuring that they will not loosen during operation. The top of the branch pipe 16 has a mounting plate 19. The mounting plate 19 can ensure the stability of the valve body 20 during operation. The external thread of the bolt 18 is connected to the inside of the mounting plate 19. The valve body 20 is fixedly connected to the inside of the mounting plate 19. The valve body 20 can precisely fit with the inside of the branch pipe 16 to realize the flow control of hydraulic oil. The bottom of the valve body 20 is slidably connected to the inside of the branch pipe 16.

[0040] Working principle: When assembling multiple hydraulic valve bodies 1, the operator manually pulls the pull plate 9. The pull plate 9 drives the connecting block 7. The connecting block 7 overcomes the elastic force of the spring-8, causing the round rod 6 to move from inside the mounting block 5 to the outside of the fixing plate 4. The trapezoidal block 2 of one hydraulic valve body 1 is aligned with the trapezoidal groove 3 of another hydraulic valve body 1 and slid in, completing the initial positioning connection. At this time, the pull plate 9 is released. Under the elastic force of the spring-8, the round rod 6 is inserted into the fixing plate 4 to play a limiting role.

[0041] During the operation of the hydraulic valve body 1, hydraulic oil is transmitted in the main pipeline 15 and the branch pipeline 16. Under normal circumstances, the second spring 12 is in a compressed state, giving the circular plate 13 a pressure in the direction of the main pipeline 15, so that the circular plate 13 fits tightly against the outside of the fixed ring 10 to prevent hydraulic oil leakage. When the internal pressure of the main pipeline 15 is too high, the limit strip 14 is pulled open, and the circular plate 13 is released from the restriction of the limit strip 14. The pressure in the main pipeline 15 pushes the circular plate 13 to compress the second spring 12, thereby opening a pressure relief channel to achieve pressure relief. The bolt 18 is threadedly connected to the threaded hole 17 to firmly fix the mounting plate 19 and the valve body 20 to the hydraulic valve body 1, ensuring that they will not loosen during operation.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
