Description

Technical Field

[0001] This utility model belongs to the field of hydraulic valve component protection technology, specifically relating to a hydraulic valve body outer sleeve reinforcement. Background Technology

[0002] Hydraulic valves, as core control components in hydraulic systems, play a crucial role in regulating the pressure, flow, and direction of hydraulic oil. The stability of their operation directly determines the operational accuracy and reliability of the entire hydraulic system. In numerous fields such as industrial production, engineering machinery, and aerospace, hydraulic valves often need to operate continuously under harsh conditions including high pressure, high-frequency vibration, temperature fluctuations, and external impacts. This places extremely high demands on the structural strength of the valve body itself. In existing technologies, hydraulic valve bodies are typically connected and fixed to the pipelines and equipment body of the hydraulic system via their own flange structure or simple mounting brackets. However, this traditional fixing method has significant drawbacks:

[0003] On the one hand, the connection points between the two ends of the hydraulic valve body and the pipeline, as well as the middle area of ​​the valve body, lack effective support and reinforcement structures. When subjected to the force of high-pressure hydraulic oil and the alternating load caused by system vibration over a long period of time, the valve body is prone to deformation and cracking. This not only affects the control accuracy of the hydraulic system, but may also lead to hydraulic oil leakage, causing equipment failure or even safety accidents. On the other hand, traditional fixed structures have limited ability to improve the bending and impact resistance of the hydraulic valve body. When the hydraulic system experiences pressure fluctuations or unexpected external collisions, the valve body is unable to withstand the instantaneous load impact, thereby shortening the service life of the hydraulic valve and increasing equipment maintenance costs and downtime losses.

[0004] To address the shortcomings in the aforementioned hydraulic valve body fixing and protection process, there is an urgent need for a hydraulic valve body outer sleeve reinforcement component. By clamping and stabilizing the hydraulic valve body outer sleeve, the overall structural strength of the valve body can be enhanced, improving its resistance to pressure, bending, and impact, thus ensuring that the hydraulic valve can operate stably and reliably under complex working conditions. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a hydraulic valve body outer sleeve reinforcement component, the specific technical solution of which is as follows:

[0006] A hydraulic valve body outer sleeve reinforcement includes two parallel clamping plates. A central hole on the surface of each clamping plate fits over a pipe body. A ring array of holes on the surface of each clamping plate fits over a fixing bolt. A locking nut for fixing the clamping plates is screwed onto the end of the fixing bolt. An extension portion is integrally formed on the lower part of each clamping plate. A connecting rod is provided between the two extension portions and is located directly below the hydraulic valve. Threaded holes are provided at both ends of the connecting rod. A threaded screw is screwed into a hole on the surface of the extension portion. A limit block is welded at the connection between the clamping plate and the extension portion. Limiting holes are provided at both ends of the connecting rod, and the limit block is movably installed inside the limit hole along the opening direction of the limit hole. A support mechanism for supporting the hydraulic valve is installed in the middle of the connecting rod.

[0007] Preferably, the support mechanism includes a hand-tightening screw that engages in a threaded hole in the middle of the connecting rod, a support plate at the end of the hand-tightening screw, a bearing for rotation between the hand-tightening screw and the support plate, a rubber pad bonded to the inner surface of the support plate, a guide rod welded to the lower surface of the support plate, and the guide rod being movably installed in a hole in the surface of the connecting rod.

[0008] Preferably, the guide rod is parallel to the axis of the hand-tightening screw.

[0009] Preferably, the rubber pad is in close contact with the lower surface of the hydraulic valve.

[0010] Preferably, the pipe body is fixed to both ends of the hydraulic valve by fixing bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Two clamping plates are fixed at both ends of the hydraulic valve by fixing bolts and locking nuts. A connecting rod is fixed between the two clamping plates by screws. Limiting blocks integrally formed on the inner surface of the clamping plates are movably installed in the limiting holes, so that the two clamping plates are fixed at both ends of the connecting rod. This facilitates the support of the hydraulic valve at both ends by the connecting rod and the clamping plates, enhances the hydraulic valve's resistance to pressure and bending, and improves the hydraulic valve's protection performance. At the same time, the support mechanism installed in the middle of the connecting rod is used to support the hydraulic valve, thereby serving as a reinforcement component to strengthen the hydraulic valve.

[0013] 2. The support mechanism consists of a hand-tightening screw, bearing, support plate, rubber pad, and guide rod. The hand-tightening screw, which is screwed into a screw hole in the middle of the connecting rod, is rotatably connected to the support plate through the bearing. This allows the support plate to be squeezed against the hydraulic valve when the hand-tightening screw rotates in the forward direction. At the same time, the rubber pad bonded to the inner surface of the support plate acts as a buffer, making it easier to fix the support plate to the hydraulic valve. The guide rod welded to the surface of the support plate is movably installed in the hole on the surface of the connecting rod, which facilitates the movement of the support plate and increases the stability of the support plate during movement. It also prevents the support plate from rotating under force. Attached Figure Description

[0018] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.

[0019] Please see Figure 1-3 This embodiment provides the following technical solution: a hydraulic valve body outer sleeve reinforcement, including two parallel clamping plates 4, a central hole on the surface of the clamping plate 4 that fits over the tube body 2, and a ring array of holes on the surface of the clamping plate 4 that fits over the fixing bolt 3. A locking nut 5 for fixing the clamping plate 4 is screwed onto the end of the fixing bolt 3. An extension portion 6 is integrally formed on the lower part of each of the two clamping plates 4. A connecting rod 7 is provided between the two extension portions 6 and is located directly below the hydraulic valve 1. Threaded holes 8 are provided at both ends of the connecting rod 7. A threaded screw 9 installed in a hole on the surface of the extension portion 6 is screwed into the threaded hole 8. A limiting plug 10 is welded at the connection between the clamping plate 4 and the extension portion 6. Limiting holes 11 are provided at both ends of the connecting rod 7, and the limiting plug 10 is movably installed inside the limiting hole 11 along the opening direction of the limiting hole 11. A support mechanism for supporting the hydraulic valve 1 is installed in the middle of the connecting rod 7.

[0020] In this embodiment, two clamping plates 4 are fixed at both ends of the hydraulic valve 1 by fixing bolts 3 and locking nuts 5. At the same time, a connecting rod 7 is fixed between the two clamping plates 4 by screw rods 9. Meanwhile, a limiting insert 10 integrally formed on the inner surface of the clamping plate 4 is movably installed in the limiting insert hole 11, so that the two clamping plates 4 are fixed at both ends of the connecting rod 7. This facilitates the connecting rod 7 and the clamping plates 4 to support both ends of the hydraulic valve 1, enhances the hydraulic valve 1's resistance to pressure and bending, and improves the protection performance of the hydraulic valve 1. At the same time, the support mechanism installed in the middle of the connecting rod 7 is used to support the hydraulic valve 1, thereby achieving the purpose of reinforcing the hydraulic valve 1 with reinforcement components.

[0021] Specifically, the support mechanism includes a hand screw 12 that is screwed into a threaded hole in the middle of the connecting rod 7. A support plate 14 is provided at the end of the hand screw 12, and a bearing 13 for rotation is provided between the hand screw 12 and the support plate 14. A rubber pad 15 is bonded to the inner surface of the support plate 14, and a guide rod 16 is welded to the lower surface of the support plate 14. The guide rod 16 is movably installed in a hole opened on the surface of the connecting rod 7. The guide rod 16 is parallel to the axis of the hand screw 12, and the rubber pad 15 is in close contact with the lower surface of the hydraulic valve 1.

[0022] In this embodiment, a support mechanism consisting of a hand-tightening screw 12, a bearing 13, a support plate 14, a rubber pad 15, and a guide rod 16 is used. The hand-tightening screw 12, which is screwed into a screw hole in the middle of the connecting rod 7, is rotatably connected to the support plate 14 through the bearing 13. This facilitates the compression of the hydraulic valve 1 by the support plate 14 when the hand-tightening screw 12 rotates in the forward direction. At the same time, the rubber pad 15 bonded to the inner surface of the support plate 14 acts as a buffer, which facilitates the fixation of the support plate 14 to the hydraulic valve 1. The guide rod 16 welded to the surface of the support plate 14 is movably installed in the hole opened on the surface of the connecting rod 7, which facilitates the guidance of the support plate 14 when it moves, increases the stability of the support plate 14 when it moves, and also prevents the support plate 14 from rotating under force.

[0023] Specifically, the pipe body 2 is fixed to both ends of the hydraulic valve 1 by fixing bolts 3.
