Description

Technical Field

[0001] This utility model relates to the field of hydraulic technology, and in particular to a threaded cartridge hydraulic pressure compensation valve. Background Technology

[0002] Hydraulic pressure compensation valves are key control components in hydraulic systems. Their core function is to automatically adjust the valve opening to maintain a relatively constant pressure difference between the valve inlet and outlet when the flow rate changes or the load fluctuates. This ensures a stable flow supply to the actuators and guarantees the smoothness and reliability of the hydraulic system. Threaded cartridge hydraulic pressure compensation valves are compact components formed by combining a threaded cartridge structure with the traditional hydraulic pressure compensation valve. They are directly inserted into the mounting hole of the hydraulic manifold or valve body using a threaded connection, simplifying the overall structure of the hydraulic system. They have become one of the mainstream components for achieving pressure compensation in small and medium-sized hydraulic systems.

[0003] Commonly used types include pressure-compensated adjustable cartridge flow valves and pressure-compensated flow regulating valves. However, existing threaded cartridge hydraulic pressure compensating valves are often fixed in their installation structure, making it difficult to adjust their extension and retraction or adjust their installation length according to actual spacing requirements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a threaded cartridge-type hydraulic pressure compensation valve, which aims to improve the problems of difficulty in adjusting the extension and retraction and adjusting its installation length according to actual spacing requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a threaded cartridge hydraulic pressure compensation valve, comprising a bolt, a threaded rod connected to the inner wall of the bolt, a fixed plate fixedly connected to the outer wall of the bolt, a motor fixedly connected to the lower surface of the fixed plate, a threaded rod II fixedly provided at the output end of the motor, a cylindrical tube threadedly connected to the outer wall of the threaded rod II, a limit post I fixedly connected to the outer wall of the cylindrical tube, a sleeve fixedly connected to the outer wall of the cylindrical tube, a limit post II rotatably connected to the outer wall of the sleeve, a clamping mechanism provided on the upper surface of the limit post II, and a limit component provided on the upper surface of the bolt, the limit component being used to limit the bolt.

[0006] Through the above technical solution, the starting motor hydraulically drives the second threaded rod to rotate hydraulically, which in turn drives the cylindrical cylinder to rotate hydraulically. The second threaded rod hydraulically drives the cylindrical cylinder to rotate hydraulically synchronously, so that the cylindrical cylinder hydraulically drives the sleeve to rotate hydraulically through the first limit pin, which in turn moves the second limit pin hydraulically. At the same time, the second limit pin moves up and down with the rotation of the cylindrical cylinder, which drives the fixed bracket to move up and down to complete the extension and retraction. This not only achieves the effect of extending the length to adapt to different distances between the pressure compensation valve body and the component to be installed, but also achieves the effect of installation and debugging through the clamping mechanism, making it compatible with different specifications of components and improving installation efficiency.

[0007] Preferably, the limiting component includes a pressure compensation valve body, the lower surface of which is disposed on the upper surface of bolt one, and bolt two is rotatably connected to the upper surface of the pressure compensation valve body.

[0008] Preferably, the clamping mechanism includes a fixed bracket, the lower surface of which is disposed on the upper surface of the second limiting post, a slide rail is fixedly connected to the outer wall of the fixed bracket, a threaded groove is opened inside the fixed bracket, a threaded post is threadedly connected inside the fixed bracket, a first fixing post is attached to the outer wall of the fixed bracket, a second fixing post is fixedly connected to the outer wall of the first fixing post, and a clamp is fixedly connected to the outer wall of the second fixing post.

[0009] Preferably, the outer wall of the threaded rod is rotatably connected to the inside of the fixed plate, and the outer wall of the cylindrical tube is rotatably connected to the inside of the limiting post.

[0010] Preferably, the outer wall of the second threaded rod is threadedly connected to the inside of the cylindrical tube, and the outer wall of the first threaded rod is rotatably connected to the inside of the second bolt.

[0011] Preferably, the outer wall of the clamp is slidably connected to the outer wall of the fixed bracket, and the outer wall of the clamp is slidably connected to the outer wall of the slide rail.

[0012] Preferably, the lower surface of the clamp is slidably connected to the upper surface of the second bolt, and the outer wall of the fixing bracket is slidably connected to the outer wall of the second bolt.

[0013] Preferably, the outer wall of the threaded column is threaded to the inside of the fixed column two, and the two ends of the threaded rod two are provided with reverse threads.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the sleeve rotates to drive the second limiting post to move, which in turn drives the cylindrical cylinder to rotate and move up and down, thereby driving the clamping mechanism to move up and down. This not only achieves the effect of extending the length to adapt to different distances between the pressure compensation valve body and the component to be installed, but also achieves the effect of installing and debugging through the clamping mechanism, making it compatible with different specifications of components and improving installation efficiency.

[0015] 2. In this utility model, the threaded column is fixed by the threaded engagement of the threaded groove, thereby fixing the second column and completing the clamping. This achieves the effect of preventing the two from loosening due to the impact of the hydraulic oil flow, thus improving service life and safety. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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.

[0019] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model is provided: a threaded cartridge type hydraulic pressure compensation valve, including a bolt 1, a threaded rod 2 threadedly connected to the inner wall of the bolt 1, a fixing plate 3 fixedly connected to the outer wall of the bolt 1, a motor 4 fixedly connected to the lower surface of the fixing plate 3, a threaded rod 5 fixedly provided at the output end of the motor 4, a cylindrical cylinder 6 threadedly connected to the outer wall of the threaded rod 5, a limit post 7 fixedly connected to the outer wall of the cylindrical cylinder 6, a sleeve 8 fixedly connected to the outer wall of the cylindrical cylinder 6, a limit post 9 rotatably connected to the outer wall of the sleeve 8, a clamping mechanism 19 provided on the upper surface of the limit post 9, and a limit component provided on the upper surface of the bolt 1, the limit component being used to limit the bolt 1; Specifically, the motor 4 drives the threaded rod 5 to rotate, which in turn drives the cylindrical cylinder 6 to rotate. During operation, the fixing plate 3 fixes the motor 4 to ensure that the position of the motor 4 does not change during operation. At the same time, the fixing plate 3 restricts the threaded rod 5 to ensure that the position of the threaded rod 5 does not change when driven to rotate by the motor 4. The threaded rod 5 also restricts the cylindrical cylinder 6, so that when the threaded rod 5 is driven to rotate by the motor 4, it synchronously drives the cylindrical cylinder 6 to rotate. This rotation of the cylindrical cylinder 6 drives the first limiting post 7 to rotate, which in turn drives the sleeve 8 to rotate, thereby moving the second limiting post 9. The cylindrical cylinder 6... The first limiting post 7 is fixed to ensure that the cylindrical tube 6 rotates synchronously with the first limiting post 7. At the same time, the second limiting post 9 restricts the sleeve 8 to ensure that the position of the sleeve 8 does not change when it rotates. The second limiting post 9 also restricts the cylindrical tube 6, so that the rotation of the cylindrical tube 6 synchronously drives the second limiting post 9 to move up and down. This up and down movement of the second limiting post 9 drives the clamping mechanism 19 to move up and down, completing the extension and retraction. This not only achieves the effect of extending the length to adapt to different distances between the pressure compensation valve body 10 and the parts to be installed, but also achieves the effect of installation and debugging through the clamping mechanism 19, making it suitable for installing parts of different specifications and improving installation efficiency.

[0020] Reference Figure 1 and Figure 5 The limiting component includes a pressure compensation valve body 10, the lower surface of the pressure compensation valve body 10 is disposed on the upper surface of bolt 1, and bolt 2 11 is rotatably connected to the upper surface of the pressure compensation valve body 10. Specifically, the pressure compensation valve body 10 is restricted by bolt 1 to prevent its position from changing, and bolt 21 is supported and restricted by the pressure compensation valve body 10 to prevent the threaded rod 2 of bolt 21 from falling off.

[0021] Reference Figure 1 , Figure 4 and Figure 5The clamping mechanism 19 includes a fixed bracket 12, the lower surface of the fixed bracket 12 is disposed on the upper surface of the second limiting post 9, a slide rail 13 is fixedly connected to the outer wall of the fixed bracket 12, a threaded groove 14 is opened inside the fixed bracket 12, a threaded post 15 is threadedly connected inside the fixed bracket 12, a first fixed post 16 is attached to the outer wall of the fixed bracket 12, a second fixed post 17 is fixedly connected to the outer wall of the first fixed post 16, and a clamp 18 is fixedly connected to the outer wall of the second fixed post 17. Specifically, by pushing the first fixed column 16 inward, the second fixed column 17 moves, which in turn moves the clamp 18. The fixed bracket 12 restricts the first fixed column 16 to prevent its position from shifting. Simultaneously, the fixed bracket 12 restricts the second fixed column 17 to ensure its position remains unchanged during movement. The second fixed column 17 also fixes the clamp 18, so that its movement synchronously moves the clamp 18. The clamp 18 moves and clamps the column, while the slide rail 13 guides it, ensuring it can only move on the outer wall of the slide rail 13. By rotating the threaded column 15 inward, the threaded groove 14 threads the threaded column 15, thus threading the second fixed column 17. After the pressure compensation valve body 10 is connected and installed with other equipment, the clamps 18 on both sides clamp and fix the parts connected to the pressure compensation valve body 10, preventing loosening due to the impact of hydraulic oil flow and improving service life and safety.

[0022] Reference Figure 1 and Figure 2 The outer wall of the threaded rod 5 is rotatably connected to the inside of the fixed plate 3, and the outer wall of the cylindrical tube 6 is rotatably connected to the inside of the limiting post 9; Specifically, the threaded rod 5 is restricted by the fixing plate 3 so that the position of the threaded rod 5 will not deviate when it is driven to rotate by the motor 4. The cylindrical cylinder 6 is restricted by the limiting post 9 so that the cylindrical cylinder 6 moves up and down synchronously with the limiting post 9 when it rotates.

[0023] Reference Figure 1 and Figure 2 The outer wall of threaded rod 2 5 is threadedly connected to the inside of cylindrical tube 6, and the outer wall of threaded rod 1 2 is rotatably connected to the inside of bolt 2 11; Specifically, the cylindrical tube 6 is restricted by the threaded rod 2 5, so that when the threaded rod 2 5 is driven to rotate by the motor 4, it synchronously drives the cylindrical tube 6 to rotate. The bolt 2 11 is restricted by the threaded rod 1 2, so that the position of the bolt 2 11 will not change.

[0024] Reference Figure 1 , Figure 4 and Figure 5The outer wall of the clamp 18 is slidably connected to the outer wall of the fixed bracket 12, and the outer wall of the clamp 18 is slidably connected to the outer wall of the slide rail 13. Specifically, the clamp 18 is restricted by the fixed bracket 12 so that the position of the clamp 18 will not shift when it moves, and the clamp 18 is guided by the slide rail 13 so that the clamp 18 can only move on the outer wall of the slide rail 13.

[0025] Reference Figure 1 , Figure 4 and Figure 5 The lower surface of the clamp 18 is slidably connected to the upper surface of the bolt 11, and the outer wall of the fixing bracket 12 is slidably connected to the outer wall of the bolt 11. Specifically, the clamp 18 slides on the upper surface of the bolt 11, so that the bolt 11 supports and restricts the clamp 18. The fixed bracket 12 slides on the upper surface of the bolt 11, so that the bolt 11 restricts and supports the fixed bracket 12.

[0026] Reference Figure 1 , Figure 4 and Figure 5 The outer wall of the threaded column 15 is threaded to the inside of the fixed column 17, and the two ends of the threaded rod 5 are provided with reverse threads. Specifically, the fixed column 17 is fixed by the threaded column 15, so that the position of the fixed column 17 will not change. The threaded rod 25 has reverse threads at both ends, so that when the threaded rod 25 is driven to rotate by the motor 4, it synchronously drives the cylindrical cylinder 6 to rotate.

[0027] Working principle: When the hydraulic pressure compensation valve needs to be extended or retracted, the starting motor 4 drives the threaded rod 5 to rotate, which in turn drives the cylindrical cylinder 6 to rotate. The threaded rod 5 drives the cylindrical cylinder 6 to rotate synchronously, so that the cylindrical cylinder 6 drives the sleeve 8 to rotate through the limiting post 7, which in turn moves the limiting post 9. At the same time, the limiting post 9 moves up and down with the rotation of the cylindrical cylinder 6, which drives the clamping mechanism 19 to move up and down to complete the extension and retraction. This not only achieves the effect of extending the length to adapt to different distances between the pressure compensation valve body 10 and the parts to be installed, but also achieves the effect of installation and debugging through the clamping mechanism 19, making it compatible with different specifications of parts and improving installation efficiency. When installing the hydraulic pressure compensation valve, pushing the first fixing column 16 inward will move the second fixing column 17, which in turn will move the clamp 18. The clamp 18 moves along the slide rail 13 to achieve clamping. Rotating the threaded column 15 inward will fix the threaded column 15 through the thread engagement of the threaded groove 14, thereby fixing the second fixing column 17. After the pressure compensation valve body 10 is connected and installed with other equipment, the clamps 18 on both sides can clamp and fix the part that is connected to the pressure compensation valve body 10, which can prevent the impact force of the hydraulic oil flow from causing the two to loosen, thus improving the service life and safety. In other words, this hydraulic pressure compensation valve not only achieves the effect of adapting the extension length to accommodate different distances between the pressure compensation valve body 10 and the component to be installed, and improves the installation efficiency by using the clamping mechanism 19 for installation and debugging, thus adapting to different specifications of components, but also prevents the impact force of hydraulic oil flow from causing loosening between the two, thereby improving service life and safety.

[0028] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
