Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve technology, specifically to an integrated hydraulic control valve body structure. Background Technology

[0002] Hydraulic valves operate on the principles of fluid mechanics, regulating and controlling hydraulic systems by controlling the flow direction, pressure, and flow rate of hydraulic fluid. There are many types of hydraulic valves, such as throttle valves, pressure reducing valves, and relief valves. Throttle valves control flow rate by changing the throttling cross-section or length, and do not have negative flow feedback, making them suitable for applications with minimal load variations. Relief valves maintain constant system pressure, prevent overload, and can also enable remote pressure regulation and system unloading. Each type has its specific function and application scenario.

[0003] Currently, hydraulic control valve bodies are usually integrated structures. If the valve core and spring in the hydraulic valve wear out or the spring becomes bent and loses elasticity during long-term use, it becomes difficult to maintain or replace the internal components of the valve body. Therefore, an integrated hydraulic control valve body structure is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated hydraulic control valve body structure, which has advantages such as easy maintenance of internal valve body components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated hydraulic control valve body structure, including a first valve body and a second valve body, a locking member between the first valve body and the second valve body, an oil inlet pipe connected to the side of the first valve body away from the second valve body, an oil outlet pipe connected to the bottom of the first valve body, and an adjusting member on the second valve body.

[0006] The locking component includes a U-shaped block, which is disposed on the side wall of the first valve body. A rotating block is rotatably connected inside the U-shaped block via a rotating shaft. A threaded rod is provided on one side of the rotating block. A raised edge plate is provided on the outer side of the opposite side of the first valve body and the second valve body. Multiple U-shaped grooves are opened on the side wall of the raised edge plate.

[0007] The adjusting component includes a piston, an adjusting rod connected to one side of the piston, the end of the adjusting rod away from the piston extending through the second valve body to the outside and connected to a guide plate, and an adjusting nut connected to the external thread of the adjusting rod.

[0008] Furthermore, the adjusting nut is rotatably connected to the side wall of the second valve body, and the side wall of the second valve body is connected to two guide rods, one end of which extends through the guide plate to the outside.

[0009] Furthermore, the threaded rod is externally threaded with a clamping screw block, and a rotating rod is fixedly connected to the side of the clamping screw block away from the threaded rod.

[0010] Furthermore, the threaded rod is located inside the U-shaped groove, and a positioning groove is provided on the side of the first valve body near the second valve body. A positioning protrusion is provided on the side of the second valve body near the first valve body, and the positioning protrusion is engaged inside the positioning groove.

[0011] Furthermore, the first valve body has an oil inlet that communicates with the oil inlet pipe inside, and a valve core is provided inside the oil inlet. A limit post is connected to the opposite side of the valve core and the piston, and a spring installed outside the limit post is provided between the valve core and the piston.

[0012] Furthermore, the guide plate is a rectangular plate, and the adjusting nut is located between the guide plate and the second valve body.

[0013] Furthermore, the first valve body and the second valve body each have three U-shaped grooves, which are distributed equidistantly around each other.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The integrated hydraulic control valve body structure is integrated into a whole by setting a first valve body and a second valve body for locking. The first valve body and the second valve body are fixed by locking components, which makes it easy to separate the first valve body and the second valve body. This facilitates maintenance or replacement of internal components. Rotating the adjusting nut clockwise or counterclockwise will cause the adjusting rod to move and push the piston to move, which can easily adjust the pressure of the spring and achieve the effect of pressure regulation.

[0021] 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.

[0022] Please see Figures 1 to 4 The integrated hydraulic control valve body structure in this embodiment includes a first valve body 1 and a second valve body 2. A locking member is provided between the first valve body 1 and the second valve body 2. An oil inlet pipe 3 is connected to the side of the first valve body 1 away from the second valve body 2. An oil outlet pipe 4 is connected to the bottom of the first valve body 1. An adjusting member is provided on the second valve body 2.

[0023] The locking component includes a U-shaped block 13, which is disposed on the side wall of the first valve body 1. A rotating block 14 is rotatably connected inside the U-shaped block 13 via a rotating shaft. A threaded rod 15 is provided on one side of the rotating block 14. A raised edge plate 21 is provided on the outer side of the opposite side of the first valve body 1 and the second valve body 2. Multiple U-shaped grooves 20 are opened on the side wall of the raised edge plate 21.

[0024] Please see Figure 1 , Figure 2 In this embodiment, the adjusting component includes a piston 6, an adjusting rod 9 connected to one side of the piston 6, the end of the adjusting rod 9 away from the piston 6 extending through the second valve body 2 to the outside and connected to a guide plate 10, an adjusting nut 11 threadedly connected to the outside of the adjusting rod 9, the adjusting nut 11 being rotatably connected to the side wall of the second valve body 2, two guide rods 12 connected to the side wall of the second valve body 2, one end of the guide rod 12 extending through the guide plate 10 to the outside, the guide plate 10 being a rectangular plate, and the adjusting nut 11 being located between the guide plate 10 and the second valve body 2.

[0025] Please see Figure 2 The first valve body 1 and the second valve body 2 each have three U-shaped grooves 20, which are distributed equidistantly around each other.

[0026] In this embodiment, the first valve body 1 has an oil inlet that communicates with the oil inlet pipe 3. The oil inlet has a valve core 5 inside. The valve core 5 and the piston 6 are connected to a limit post 7 on opposite sides. A spring 8 is installed outside the limit post 7 between the valve core 5 and the piston 6.

[0027] It is understandable that by setting the first valve body 1 and the second valve body 2 to be locked and integrated into a whole, and the first valve body 1 and the second valve body 2 are fixed by locking components, it is convenient to separate the first valve body 1 and the second valve body 2, so as to facilitate maintenance or replacement of internal components.

[0028] It should be noted that by rotating the adjusting nut 11, since the adjusting nut 11 is threadedly connected to the adjusting rod 9, and under the limiting effect of the sliding connection between the guide plate 10 and the guide rod 12, the adjusting rod 9 can be translated when the adjusting nut 11 is rotated, and the piston 6 can move to the left or right to adjust the pressure of the spring 8.

[0029] The threaded rod 15 is externally threaded with a clamping screw block 16, and a rotating rod 17 is fixedly connected to the side of the clamping screw block 16 away from the threaded rod 15.

[0030] The rotating rod 17 facilitates the rotation of the clamping screw block 16, which presses against the side wall of the flange plate 21 to fix the first valve body 1 and the second valve body 2.

[0031] The threaded rod 15 is located inside the U-shaped groove 20. The first valve body 1 has a positioning groove 18 on the side near the second valve body 2. The second valve body 2 has a positioning protrusion 19 on the side near the first valve body 1. The positioning protrusion 19 is engaged inside the positioning groove 18.

[0032] The working principle of the above embodiment is as follows: When it is necessary to maintain the internal components, by rotating the rotating rod 17 to drive the clamping screw block 16 to rotate away from the convex edge plate 21, the threaded rod 15 can be flipped outward to move out of the U-shaped groove 20. After completing the unlocking operation in sequence, the first valve body 1 and the second valve body 2 can be separated, which is convenient for maintaining the internal components. When using the hydraulic valve again, by rotating the adjusting nut 11 clockwise or counterclockwise, the adjusting rod 9 can be moved to push the piston 6 to move, which is convenient for adjusting the pressure of the spring 8 and achieving the effect of pressure regulation.
