Description

Technical Field

[0001] The utility model relates to the technical field of installing directional valves, in particular to a directional valve suitable for multi-angle installation. Background Art

[0002] Directional valves are very important control components in hydraulic or pneumatic systems. They are primarily used to control the flow direction of fluid (hydraulic oil or compressed air), thereby controlling the movement direction of actuators (such as hydraulic cylinders and pneumatic cylinders).

[0003] The multi-angle installation directional valve currently used is connected to the pipeline through a flange. The multi-angle installation of the directional valve can be achieved by adjusting the relative angle between the flanges during connection. After adjusting the installation angle, even if the system is affected by large fluid pressure, vibration or temperature changes during operation, the angle can be kept unchanged.

[0004] The currently used multi-angle installation directional valve has achieved multi-angle installation, but requires the use of more bolts, and the tightness of the bolts has an important influence on the sealing and angle stability. Therefore, when adjusting the angle, it is necessary to loosen multiple bolts first, adjust the angle and then re-tighten the bolts evenly. The process is relatively cumbersome, and if the bolts are not tightened evenly, the flange will be deformed, which will affect the sealing and angle accuracy and affect the use. Therefore, a directional valve suitable for multi-angle installation is proposed to solve the above problems. Utility Model Content

[0035] Reference Figure 1 、 Figure 2 and Figure 5 The present invention provides an embodiment of a directional valve suitable for multi-angle installation, comprising a pipe 1 and a directional valve body 5. An angle adjustment assembly is fixedly connected to both sides of the directional valve body 5, and a connecting assembly is installed on the outside of the pipe 1. The angle adjustment assembly includes a plurality of connecting blocks 10, two of which are fixedly connected to the sides of the directional valve body 5, and the other two connecting blocks 10 are fixedly connected to adjustment blocks 12. The inner sides of the plurality of connecting blocks 10 are rotatably connected to connecting rods 11, and the inner sides of the adjustment blocks 12 are slidably connected to the fixed rod 6. Two connecting rings 2 are fixedly connected to the bottom side of the fixed rod 6, and the inner sides of the two fixed rods 6 are each provided with a plurality of adjustment holes 7. A housing 13 is slidably connected to the inner side of one of the adjustment holes 7, and a push rod 14 is slidably connected to the interior of the housing 13. A plurality of clamping blocks 24 are rotatably connected to the outer side of the push rod 14, and the outer side of the housing 13 is slidably connected to the adjustment block 12. The top ends of the two fixed rods 6 are fixedly connected to a top block 8. While the adjusting block 12 slides up and down on the outside of the fixed rod 6, the tilt angle is precisely adjusted, and then the push rod 14 is pressed to retract the clamping block 24 into the shell 13. After entering the adjusting hole 7, the push-pull rod 14 is released so that the push-pull rod 14 drives the clamping block 24 to be clamped on the outside of the adjusting block 12 under the elastic force of the spring 19, and the rotating block 15 is rotated to make it more firmly clamped, thereby realizing a simple and convenient adjustment of the angle of the directional valve.

[0036] Reference Figure 2 、 Figure 3 and Figure 4The connection assembly includes multiple connecting rings 2, two of which are mounted on the outside of the middle portion of the pipe 1. Both ends of the connecting rings 2 are fixedly connected to a fixing block 4, and two bolts 3 are installed inside each of the fixing blocks 4. Multiple connecting rings 2 are mounted on both ends of the pipe 1, and both ends of the connecting rings 2 are fixedly connected to the inside of the fixing block 4, which is mounted outside of the bolts 3. The connecting rings 2 are installed using the bolts 3, thereby securing the adjustment assembly and the directional valve body 5 together on the outside of the pipe 1, thereby ensuring stable fixation and adjustment of the directional valve body 5 and the adjustment assembly. A U-shaped block 17 is fixedly connected to the outside of one of the connecting rings 2. Rotating rods 15 are rotatably connected to the inside of each end of the U-shaped block 17. Both rotating rods 15 are fixedly connected to connecting blocks 16 on the outside. Both connecting blocks 16 are fixedly connected to the bottom of the directional valve body 5. The rotating rod 15 rotates inside the U-shaped block 17, driving the directional valve body 5 to swing left and right.

[0037] Reference Figure 5 、 Figure 6 Slideways 9 are defined on the outside of both ends of the fixed rod 6. Slide blocks 23 are fixedly connected to the inside of both ends of the adjustment block 12. Both slide blocks 23 are slidably connected to the inside of the two slideways 9. The adjustment block 12 slides securely within the slideways 9 via the internal slide blocks 23, thereby enabling quick and stable adjustment of the tilt angle of the directional valve body 5. A groove 20 is defined on the inside of the housing 13. Two slide blocks 1 (21) are fixedly connected to the sides of the push rod 14. Both slide blocks 1 (21) are slidably connected to the sides of the groove 20. As the push rod 14 slides with the slide blocks 1 (21) in the groove 20, the push rod 14 rotates, causing the slide blocks 1 (21) and the push-pull rod to engage within the housing 13, thereby securely retaining the engagement block 24 within the housing 13. One end of the push rod 14 is rotatably connected to a circular plate 18. This circular plate 18 is fixedly connected to a spring 19, one end of which is fixedly connected to the inside of the housing 13. A rotating block 22 is rotatably connected to the outside of the housing 13.

[0038] Working principle: By rotating the rotating rod 15 inside the U-shaped block 17, the directional valve body 5 is driven to swing left and right. While the adjustment block 12 slides up and down outside the fixed rod 6, the tilt angle is precisely adjusted. Then, the push rod 14 is pressed to retract the clamping block 24 into the housing 13. After entering the adjustment hole 7, the push-pull rod 14 is released. The push-pull rod 14 drives the clamping block 24 to engage the outside of the adjustment block 12 under the elastic force of the spring 19. The rotating block 15 is rotated to make the engagement more stable, thereby achieving simple and convenient adjustment of the angle of the directional valve. The connecting ring 2 is installed with the bolt 3, so that the adjustment assembly and the directional valve body 5 are installed together on the outside of the pipeline 1, thereby achieving stable fixation and adjustment of the directional valve body 5 and the adjustment assembly.
