DETAILED DESCRIPTION

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0026] In order to solve the problem that the hydraulic joints used for hydraulic valves use a single sealing ring to provide sealing, which is very prone to leakage and reduces the sealing connection effect of the hydraulic joints, please refer to Figures 1 to 5 The structure of the device body is a hydraulic joint body 1 with a hollow interior and three connecting pipes 2 with threads on the surface. The connecting pipes 2 are threadedly connected with hydraulic components such as pumps, delivery pipelines, reversing valves, and stop valves to achieve installation and communication of the hydraulic joint. The centripetal side of the three connecting pipes 2 is connected with the hydraulic joint body 1, and the centripetal side of the connecting pipes 2 is welded to the hydraulic joint body 1. A sealing component 3 is provided on the outer peripheral side of the connecting pipe 2. The sealing function provided by the sealing component 3 prevents leakage at the connection between the connecting pipe 2 and hydraulic components such as pumps, delivery pipelines, reversing valves, and stop valves, thereby improving the sealing connection effect of the hydraulic joint.

[0027] The sealing assembly 3 includes a plug-in tube 4 and a sealing ring 6. The outer peripheral side of the plug-in tube 4 is connected to the connecting tube 2, and the outer peripheral side of the plug-in tube 4 is welded to the connecting tube 2 to fix the position of the plug-in tube 4 and improve the structural stability of the components of the hydraulic joint. The side of the plug-in tube 4 is fixedly connected to a fixed magnetic ring 9 through an annular groove to fix the position of the fixed magnetic ring 9. The side of the fixed magnetic ring 9 is magnetically connected to a movable magnetic ring 8. The side of the movable magnetic ring 8 away from the fixed magnetic ring 9 is fixedly connected to the sealing ring 6, and the side of the sealing ring 6 close to the movable magnetic ring 8 abuts against the plug-in tube 4. At the same time, under the abutting action of the plug-in tube 4, a certain gap is provided at the connection between the fixed magnetic ring 9 and the movable magnetic ring 8 to prevent the fixed magnetic ring 9 and the movable magnetic ring 8 from being broken when the sealing ring 6 is abutted and squeezed, thereby improving the structural stability of the components of the hydraulic joint.

[0028] At the same time, the sealing ring 6 is provided to provide a sealing effect to prevent leakage when the hydraulic joint is threadedly connected with hydraulic components such as pumps, delivery pipelines, reversing valves, and stop valves. The outer tube surface of the plug-in tube 4 is sleeved with a sealing outer ring 5, and the inner tube surface of the plug-in tube 4 is plugged with a sealing inner ring 7. The sides of the sealing outer ring 5 and the sealing inner ring 7 are fixedly connected to the sealing ring 6. The provided sealing outer ring 5 and the sealing inner ring 7 provide a sealing effect on the hydraulic joint, thereby further improving the sealing connection effect of the hydraulic joint with hydraulic components such as pumps, delivery pipelines, reversing valves, and stop valves, and preventing leakage at the connection between the hydraulic joint and hydraulic components such as pumps, delivery pipelines, reversing valves, and stop valves.

[0029] A storage component 10 for storing active metals is arranged on the side of the hydraulic joint body 1. The storage component 10 is used to store active metals such as aluminum and zinc, so that the hydraulic joint body 1 is in contact with and connected to the parts of the storage component 10. When the hydraulic joint is oxidized and corroded, the reducing property provided by the active metals such as aluminum and zinc can realize the anti-corrosion effect on the hydraulic joint, thereby extending the service life of the hydraulic joint. The storage component 10 includes a storage ring 11 and a threaded block 18, so that active metals such as aluminum and zinc are placed inside the storage ring 11 to realize the storage effect of active metals such as aluminum and zinc. The side of the storage ring 11 is welded to the hydraulic joint body 1 to fix the position of the storage ring 11.

[0030] A rubber plate 12 is abutted against one side of the storage ring 11 away from the hydraulic joint body 1. The rubber plate 12 provides a shielding effect and a sealing effect to prevent the outside air from contacting with active metals such as aluminum and zinc for oxidation, thereby reducing the reducing property of the active metals to the hydraulic joint, thereby improving the anti-corrosion effect of the hydraulic joint and extending the service life of the hydraulic joint. A support plate 13 is fixedly connected to the side of the rubber plate 12. The support plate 13 provides a supporting effect on the rubber plate 12, strengthens the uniformity of the abutment between the rubber plate 12 and the storage ring 11, thereby improving the sealing effect of the rubber plate 12 on the storage ring 11. A connecting plate 14 is welded to the top surface of the support plate 13 to fix the position of the connecting plate 14. A connecting rod 15 is inserted into the side of the connecting plate 14 through a through groove. A rotating block 16 and a threaded rod 17 are respectively welded to the two end surfaces of the connecting rod 15. The connecting rod 15 provides a connecting effect.

[0031] When the rotating block 16 rotates, the threaded rod 17 is driven to rotate synchronously during the transmission process. The side of the rotating block 16 close to the connecting rod 15 abuts against the connecting plate 14, and the threaded rod 17 is threadedly connected to the threaded block 18, so that the threaded rod 17 moves laterally along the thread path of the threaded block 18, which is convenient for reducing the distance between the connecting plate 14 and the threaded block 18. During the transmission process, the sealing and shielding effect of the rubber plate 12 on the storage ring 11 is strengthened, and at the same time, the shielding effect of the rubber plate 12 on the storage ring 11 is released, and active metals such as aluminum and zinc are replaced to prevent aluminum, zinc and other active metals from being oxidized after replacing the hydraulic joint for a long time, and the reduction effect provided to the hydraulic joint is weakened, thereby improving the anti-corrosion effect of the hydraulic joint and extending the service life of the hydraulic joint. The bottom and side surfaces of the threaded block 18 are fixedly connected to the storage ring 11 and the hydraulic joint body 1 respectively.

[0032] The working principle, size and model are irrelevant to the function of this application, so they are not described in detail. The control method of the utility model is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0033] How it works

[0034] When using the hydraulic joint for a hydraulic valve, the user makes the connecting pipe 2 of the hydraulic joint be threadedly connected with the hydraulic components such as a pump, a delivery pipeline, a reversing valve, and a stop valve through the threads on its surface, so that the hydraulic components such as the pump, the delivery pipeline, the reversing valve, and the stop valve abut against the sealing ring 6, so that the sealing ring 6 provides a sealing effect to prevent leakage at the connection between the hydraulic joint and the hydraulic components such as the pump, the delivery pipeline, the reversing valve, and the stop valve. At the same time, the provided sealing outer ring 5 and the sealing inner ring 7 provide a sealing effect to further strengthen the sealing connection between the hydraulic components such as the pump, the delivery pipeline, the reversing valve, and the stop valve and the hydraulic joint. The plug-in tube 4 is provided to provide support and extension, and the fixed magnetic ring 9 and the movable magnetic ring 8 are magnetically connected to prevent the sealing outer ring 5, the sealing ring 6 and the sealing inner ring 7 from falling off and being lost, thereby improving the structural stability of the components of the hydraulic connector. At the same time, under the interaction between the structures, the sealing outer ring 5, the sealing ring 6 and the sealing inner ring 7 are prevented from shaking and deviating, which would cause leakage at the connection between the hydraulic connector and hydraulic components such as pumps, delivery pipelines, reversing valves and stop valves, thereby improving the sealing connection effect between the hydraulic connector and hydraulic components such as pumps, delivery pipelines, reversing valves and stop valves.

[0035] The active metals such as aluminum and zinc stored in the storage ring 11 can provide a reduction effect on the hydraulic joint under the welding effect of the side of the storage ring 11 and the hydraulic joint body 1, so as to prevent the hydraulic joint from being oxidized and corroded after long-term use, and the active metals such as aluminum and zinc can reduce the hydraulic joint, so as to replace the oxidized hydraulic joint with the active metals such as aluminum and zinc, so as to achieve the anti-corrosion effect on the hydraulic joint, thereby extending the service life of the hydraulic joint, and the rotating block 16 can be rotated, and the threaded rod 17 can be moved laterally along the threaded path of the threaded block 18 during the transmission process, so as to facilitate the release of the abutment effect of the rotating block 16 on the connecting plate 14, and the connecting plate 14 and the supporting plate 13 can be rotated with the connecting rod 15 as the center of the circle during the transmission process, so as to release the sealing and shielding effect of the rubber plate 12 on the storage ring 11, so as to facilitate the replacement of the active metals such as aluminum and zinc stored in the storage ring 11, and prevent the active metals such as aluminum and zinc from being weakened after long-term use, thereby improving the anti-corrosion effect on the hydraulic joint and extending the service life of the hydraulic joint.
