Description

Technical Field

[0001] This utility model relates to the field of rotary joint assembly technology, and in particular to a wear-resistant rotary joint assembly. Background Technology

[0002] A rotary joint assembly is a connecting device used to transfer fluids, gases, electrical energy, and other media between stationary and rotating equipment. The function of the rotary joint is to input liquids, gases, and other media from one side of the pipeline into rotating or reciprocating equipment and then discharge them from it. It is a sealing device for connection, which can ensure the stable transmission of media during equipment rotation, prevent media leakage, and ensure the normal operation of the equipment.

[0003] In the existing technology, the rotary joint assembly will continuously wear due to the influence of the internal fluid during use. Wear inside the assembly will affect the performance and service life. It is also impossible to detect fluid abnormalities in time and replace the assembly. If a breakage occurs during use, it will cause certain economic losses. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art where rotary joint assemblies are continuously worn due to the influence of the internal fluid during use. Wear inside the assembly affects the performance and service life, and abnormal fluid conditions cannot be detected and replaced in time. If breakage occurs during use, it will cause certain economic losses. Therefore, this invention proposes a wear-resistant rotary joint assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wear-resistant rotary joint assembly includes an assembly body, one end of which is fixedly connected to a first threaded tube, and the other end of which is fixedly connected to a second threaded tube. A guide tube is fixedly connected inside the assembly body. A threaded hole is formed on the inner wall of the top of the assembly body. A spiral guide groove is formed on the inner wall of the guide tube. A housing is fixedly connected to the inner wall of the assembly body above the guide tube. A controller is fixedly connected to the inner wall of the housing. A pressure sensor is fixedly connected to the inner wall of the housing. A pressure-sensing hole is formed on the wall of the guide tube. An alarm is fixedly connected to the top of the assembly body. The pressure sensor and the alarm are electrically connected to the controller.

[0006] Preferably, a pressure plate is slidably provided on the inner wall of the pressure sensing hole, the pressure plate is slidably provided on the inner wall of the sensing hole, a slide rod is fixedly connected to the top of the pressure plate, the top wall of the slide rod extends into the interior of the box and is fixedly connected to a pressure block, and the pressure block is located below the pressure sensor.

[0007] Preferably, a metal elastic strip is fixedly connected to the inner wall of the guide tube at the sensing hole, and the bottom of the metal elastic strip is pressed against the upper surface of the pressure plate.

[0008] Preferably, a guide ring is fixedly connected to the inner wall of the bottom end of the box, and the rod wall of the slide rod is slidably disposed on the inner wall of the guide ring.

[0009] Preferably, a guide slider is fixedly connected to the side wall of the pressure plate, and a guide groove is formed on the inner wall of the guide tube located in the sensing hole. The guide slider is slidably disposed on the inner wall of the guide groove.

[0010] Preferably, the bottom sidewall of the pressure plate has a rounded corner.

[0011] Compared with the prior art, this utility model provides a wear-resistant rotary joint assembly, which has the following beneficial effects: 1. This wear-resistant rotary joint assembly allows the medium to flow into the guide tube after entering the assembly body. The spiral guide groove regulates the flow path of the medium, reduces turbulence during transmission, and minimizes impact wear on the guide tube wall. It also improves the stability of medium delivery and avoids pressure fluctuations caused by turbulent medium flow. The threaded hole on the inner wall at the top of the assembly body can be used to install auxiliary components such as seals and detection elements to further enhance the sealing performance or expand the functionality of the assembly.

[0012] 2. This wear-resistant rotary joint assembly transmits the detected pressure signal to the controller via a pressure sensor. The controller analyzes the signal, and if the pressure exceeds the preset safety range, it immediately controls the alarm to issue an alarm signal, such as an audible and visual alarm, to remind staff to promptly troubleshoot faults such as pipeline blockage or medium overpressure, and to avoid component damage or medium leakage due to abnormal pressure.

[0013] 3. This wear-resistant rotary joint assembly has a sliding rod fixed to the top of the pressure plate. The top rod wall extends into the housing and is fixedly connected to the pressure block. The pressure block is located below the pressure sensor. When the pressure of the medium in the guide tube increases, the medium pushes the pressure plate upward, and the sliding rod drives the pressure block upward to squeeze the pressure sensor. When the pressure decreases, the pressure plate resets downward under the action of the metal elastic strip fixed to the inner wall of the pressure sensing hole in the guide tube. The bottom of the metal elastic strip is pressed against the upper surface of the pressure plate, which has a pre-tightening force to ensure that the pressure plate is in close contact with the medium and to assist the pressure plate in resetting.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A wear-resistant rotary joint assembly includes a component body 1, one end of which is fixedly connected to a first threaded tube 2, and the other end of which is fixedly connected to a second threaded tube 3. A guide tube 4 is fixedly connected inside the component body 1. A threaded hole 5 is formed on the inner wall of the top end of the component body 1. A spiral guide groove is formed on the inner wall of the guide tube 4. A housing 6 is fixedly connected to the inner wall of the component body 1 above the guide tube 4. A controller 7 is fixedly connected to the inner wall of the housing 6. A pressure sensor 8 is fixedly connected to the inner wall of the housing 6. A pressure sensing hole is formed on the wall of the guide tube 4. An alarm 9 is fixedly connected to the top end of the component body 1. The pressure sensor 8 and the alarm 9 are electrically connected to the controller 7.

[0018] A pressure plate 10 is slidably provided on the inner wall of the pressure sensing hole. The pressure plate 10 is slidably provided on the inner wall of the sensing hole. A slide rod 11 is fixedly connected to the top of the pressure plate 10. The top wall of the slide rod 11 extends into the interior of the box 6 and is fixedly connected to a pressure block 12. The pressure block 12 is located below the pressure sensor 8. A metal elastic strip 13 is fixedly connected to the guide tube 4 on the inner wall of the sensing hole. The bottom of the metal elastic strip 13 is pressed against the upper surface of the pressure plate 10.

[0019] The component body 1 is the core load-bearing component of the rotary joint, providing the installation foundation for various functional structures. The first threaded pipe 2 fixed at one end of the component body 1 and the second threaded pipe 3 fixed at the other end are used to connect external pipelines. Through the threaded engagement, the component body 1 can be firmly connected to the pipeline for conveying the medium, ensuring that the medium can enter the interior of the component body 1 through the first threaded pipe 2 and then be conveyed to the target equipment through the second threaded pipe 3, realizing the medium transmission in the rotating state, such as the lubricating oil transmission of rotating parts of mechanical equipment.

[0020] When the medium enters the component body 1, it flows into the guide tube 4. The spiral guide groove can regulate the flow path of the medium, reduce the turbulence of the medium during the transmission process, reduce the impact and wear of the medium on the tube wall of the guide tube 4, and at the same time improve the stability of the medium delivery and avoid pressure fluctuations caused by the turbulent flow of the medium. The threaded hole 5 opened on the inner wall of the top of the component body 1 can be used to install auxiliary components such as seals and detection elements to further enhance the sealing performance of the component or expand its functions.

[0021] The controller 7 fixed to the inner wall of the housing 6 is the core control unit. The pressure sensor 8 fixed to the inner wall of the housing 6 is used to monitor the pressure of the medium in the guide tube 4. The alarm 9 fixed to the top of the component body 1 is used to issue a warning when the pressure is abnormal. The pressure-sensing hole opened on the wall of the guide tube 4 is the key channel for pressure transmission. The pressure plate 10 slidably set on the inner wall of the pressure-sensing hole can directly contact the medium in the guide tube 4. When the medium pressure changes, it will push the pressure plate 10 to move up and down along the pressure-sensing hole.

[0022] A sliding rod 11 is fixed at the top of the pressure plate 10. The top rod wall extends into the box 6 and is fixedly connected to the pressure block 12. The pressure block 12 is located below the pressure sensor 8. When the pressure of the medium in the guide tube 4 increases, the medium pushes the pressure plate 10 to move upward. The sliding rod 11 then drives the pressure block 12 to press the pressure sensor 8 upward. When the pressure decreases, the pressure plate 10 resets downward under the action of the metal elastic strip 13 fixed in the inner wall of the pressure sensing hole of the guide tube 4. The bottom of the metal elastic strip 13 is pressed tightly against the upper surface of the pressure plate 10, which has a pre-tightening force to ensure that the pressure plate 10 is in close contact with the medium. At the same time, it assists the pressure plate 10 in resetting. The pressure sensor 8 transmits the detected pressure signal to the controller 7. The controller 7 analyzes the signal. If the pressure exceeds the preset safety range, it immediately controls the alarm 9 to issue an alarm signal, such as an audible and visual alarm, to remind the staff to check for faults such as pipeline blockage or medium overpressure in time, so as to avoid component damage or medium leakage due to abnormal pressure.

[0023] To ensure that the slide bar 11 moves only in the vertical direction, such as Figure 1-4 As shown, a guide ring 14 is fixedly connected to the inner wall of the bottom end of the box 6, the rod wall of the slide rod 11 is slidably disposed on the inner wall of the guide ring 14, a guide slider 15 is fixedly connected to the side wall of the pressure plate 10, a guide groove is provided on the inner wall of the guide tube 4 located in the sensing hole, the guide slider 15 is slidably disposed on the inner wall of the guide groove, and a rounded corner is provided on the bottom side wall of the pressure plate 10.

[0024] The guide ring 14 fixed to the inner wall of the bottom end of the box 6 slides against the wall of the slide rod 11, which restricts the movement trajectory of the slide rod 11 and ensures that the slide rod 11 moves only in the vertical direction. This prevents the slide rod 11 from deviating and causing the pressure block 12 to fail to accurately squeeze the pressure sensor 8, thus ensuring the accuracy of pressure monitoring. The guide slider 15 fixed on the side wall of the pressure plate 10 slides in the guide groove opened in the inner wall of the pressure sensing hole of the guide tube 4, further enhancing the stability of the sliding of the pressure plate 10 and preventing the pressure plate 10 from tilting under the action of the medium pressure, ensuring uniform pressure transmission. The rounded corners opened in the bottom side wall of the pressure plate 10 can reduce the resistance when the pressure plate 10 contacts the medium, prevent the medium from generating eddies due to the sharp edge of the pressure plate 10 when it flows, and at the same time prevent the edge of the pressure plate 10 from scratching the inner wall of the guide tube 4, reducing wear.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
