Technical Field
[0001] This utility model relates to the field of valve equipment technology, and in particular to an automatic disassembly device for valve sealing rings. Background Technology
[0002] In industrial fluid control systems, valve sealing performance is a key factor in ensuring the safe and efficient operation of the system. As the core sealing element of a valve, the sealing ring is subject to long-term effects from fluid pressure, temperature changes, and mechanical vibrations, requiring periodic replacement to maintain the valve's sealing performance. However, existing sealing ring disassembly methods and techniques have many limitations, posing significant challenges to maintenance work.
[0003] Currently, the removal of sealing rings typically relies on manual operation using simple tools such as pry bars and screwdrivers. This method is not only inefficient but also prone to damaging the sealing rings and valves during the process. Manual disassembly often results in uneven force due to a lack of precise control, potentially deforming or damaging the sealing rings, or even scratching the valve's sealing surface, affecting its sealing performance. Furthermore, manual operation requires operators to possess certain experience and skills; otherwise, improper operation can easily lead to disassembly failure or even safety accidents.
[0004] Besides the limitations of manual operation, existing auxiliary disassembly tools also have significant shortcomings. Most of these tools have simple structures and limited functions, making them unable to automate operations. During disassembly, these tools often fail to provide sufficient stability and reliability, easily becoming stuck or slipping, further reducing disassembly efficiency. These problems not only increase maintenance costs and workload but may also lead to prolonged equipment downtime, impacting production efficiency. Utility Model Content

[0007] Furthermore, the angle conversion mating part includes a slide groove formed on the base plate, a guide block is provided in the middle of the slide groove, and the slide groove is divided into a first slide track and a second slide track by the guide block. When the support part is close to the disassembly part, the slider slides along the first slide track, and when the support part is away from the disassembly part, the slider slides along the second slide track.
[0008] Furthermore, along the sliding trajectory of the slider, the bottom surface height of the second slide inlet is lower than the bottom surface height of the first slide, and the bottom surface height of the second slide outlet is higher than the bottom surface height of the first slide.

The plate has a first state bent at an obtuse angle and a second state bent at an acute angle. When the plate changes from the first state to the second state, it can disassemble the sealing ring from the valve. The elastic member is used to drive the plate in the second state back to the first state.
[0012] Furthermore, the insert plate includes a first folding plate disposed on the fixing member for support and a second folding plate for disassembly. The second folding plate is hinged to one end of the first folding plate. One end of the elastic member is connected to the fixing member, and the other end of the elastic member is connected to the second folding plate.
[0013] Furthermore, the drive unit includes a drive motor mounted on the base plate and a drive screw connected to the power output end of the drive motor, the drive screw being threadedly connected to the support base.

[0018] To make the technical problems, technical solutions, and beneficial effects to be solved by this embodiment clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this embodiment and are not intended to limit this embodiment.
[0019] Please refer to the following: Figures 1 to 6 The automatic valve sealing ring removal device provided in this embodiment will now be described. The automatic valve sealing ring removal device of this embodiment includes a base plate 1, a support part 2, a drive part 3 and a removal part 4 disposed on the base plate 1 for supporting the valve. The support part 2 is located upstream of the removal part 4. The drive part 3 is connected to the support part 2 and is used to drive the support part 2 to move closer to or away from the removal part 4.
[0020] The support part 2 includes a support base 21 connected to the drive part 3, and a rotating seat 22 rotatably mounted on the support base 21. An angle conversion part 5 is provided between the rotating seat 22 and the support base 21. An angle conversion mating part 6 is provided on the base plate 1. The angle conversion part 5 and the angle conversion mating part 6 cooperate to drive the rotating seat 22 to rotate horizontally relative to the support base 21 as the support base 21 moves away from the disassembly part 4.
[0021] This embodiment of an automatic valve sealing ring removal device, through the cooperation of the angle conversion part 5 and the angle conversion mating part 6, can drive the rotating seat 22 to rotate horizontally during the movement of the support base 21, so that the insertion plate 41 can change from an obtuse angle state to an acute angle state, thereby smoothly inserting and removing the sealing ring, which is beneficial to significantly improve the removal efficiency, reduce the number of operation steps, and reduce labor intensity.
[0022] Based on the overall description of the above structure, an exemplary structure of an automatic valve sealing ring removal device in this embodiment is as follows: Figure 1As shown. The drive unit 3 includes a drive motor 31 mounted on the base plate 1 and a drive screw 32 connected to the power output end of the drive motor 31. The drive screw 32 extends along the length direction of the base plate 1. The support unit 2 is connected to the drive screw 32 and can be driven by the drive screw 32 to slide along the length direction of the base plate 1, thereby moving to the disassembly unit 4 for easy disassembly of the sealing ring.
[0023] In this embodiment, as Figure 2 As shown, the upper part of the support base 21 is provided with a receiving groove for accommodating the valve. The size of the receiving groove is the same as the size of the middle part of the valve body. When the valve is placed in the receiving groove, the receiving groove can just hold the valve in place to prevent the valve from falling off.
[0024] To facilitate smoother sliding of the support base 21, preferably, such as Figure 1 and Figure 3 As shown, the base plate 1 is provided with a guide groove 11 for guiding the sliding of the support base 21. The guide groove 11 provides a clear sliding direction for the support base 21, reducing the risk of failure caused by the offset of the support base 21 and improving the overall performance and reliability of the device.
[0025] And as a further preferred option, refer to Figure 3 As shown, a limiting block 12 is provided within the guide groove 11 to restrict the sliding of the support base 21. By providing the limiting block 12 within the guide groove 11, the sliding range of the support base 21 can be effectively limited, preventing the support base 21 from exceeding the predetermined position during movement, which could lead to device malfunction or damage. This design not only improves the safety of the device but also ensures the accuracy and stability of the disassembly process, further enhancing the performance and service life of the device. The setting of the limiting block 12 makes the device more stable and reliable during operation, reducing downtime caused by unexpected situations and improving production efficiency.
[0026] In this embodiment, as a specific preferred implementation, such as Figure 5 and Figure 6 As shown, the disassembly part 4 includes a plate 41 inserted between the valve and the sealing ring, and an elastic member 43 that connects the fixing member 42 and the plate 41 at both ends respectively. The plate 41 has a first state bent at an obtuse angle and a second state bent at an acute angle. When the plate 41 changes from the first state to the second state, the plate 41 can remove the sealing ring from the valve. The elastic member 43 is used to drive the plate 41 in the second state to return to the first state.
[0027] By incorporating a slide plate 41 that can be inserted between the valve and the sealing ring, and an elastic element 43 connecting the fixing element 42 and the slide plate 41, the slide plate 41 can be transformed from an obtuse angle to an acute angle, thus facilitating the smooth removal of the sealing ring. The shape-changing design of the slide plate 41 not only improves disassembly efficiency but also reduces the risk of damage to the sealing ring and valve. The reset function of the elastic element 43 further optimizes the disassembly process, ensuring that the slide plate 41 automatically returns to its initial state after disassembly, preparing for the next operation. This design not only improves the automation of the disassembly process but also reduces operational steps, lowers labor intensity, and further enhances the practicality and efficiency of the device.
[0028] And as a specific preferred implementation method, such as Figure 6 As shown, the insert plate 41 includes a first folding plate 411 disposed on the fixing member 42 for support and a second folding plate 412 for disassembly. The second folding plate 412 is hinged to one end of the first folding plate 411. One end of the elastic member 43 is connected to the fixing member 42, and the other end of the elastic member 43 is connected to the second folding plate 412.
[0029] By dividing the insert plate 41 into a first folding plate 411 and a second folding plate 412 and connecting them with a hinge, the shape of the insert plate 41 becomes more flexible. This design not only enhances the adaptability of the insert plate 41, enabling it to better accommodate sealing rings of different sizes and shapes, but also improves the service life of the insert plate 41. The connection method of the elastic element 43 further ensures the stability of the insert plate 41 during disassembly and repositioning, reducing possible jamming or slippage during operation.
[0030] After the disassembly unit 4 completes the disassembly of the sealing ring on one side of the valve, in order to facilitate the automatic disassembly of the sealing ring on the other side of the valve, in this embodiment, an angle conversion unit 5 is provided in the support unit 2, and an angle conversion mating unit 6 is provided on the base plate 1 to realize the automatic rotation of the valve, thereby facilitating the smooth completion of the sealing ring disassembly process.
[0031] In this regard, as a preferred implementation method, refer to Figure 2 As shown, the angle conversion part 5 includes a support rod 51 disposed in the middle of the bottom surface of the rotating seat 22, a slide rod 52 disposed at the bottom of the support rod 51, and a slider 53 disposed at the bottom of the slide rod 52. The support rod 51 passes through the support base 21 and is fixedly connected to the rotating seat 22. The bottom of the support rod 51 is rotatably connected to one end of the slide rod 52, and the slider 53 is rotatably disposed at the bottom of the other end of the slide rod 52.
[0032] The combination of support rod 51, slide rod 52, and slider 53 enables the rotating seat 22 to flip horizontally relative to the support base 21. This design not only enhances the adaptability of the device, allowing it to better accommodate valves and sealing rings of different sizes, but also improves the stability of the slide plate 41 during disassembly. The sliding of slider 53 within the groove 61 ensures the smooth flipping of the rotating seat 22, reducing potential jamming or slippage during operation. Compared to simpler tools in the prior art, this design significantly improves the reliability and safety of the disassembly process, reducing reliance on operator experience and skills.
[0033] At the same time, such as Figures 2 to 4 As shown, the angle conversion mating part 6 includes a slide groove 61 formed on the base plate 1. A guide block 62 is provided in the middle of the slide groove 61. The slide groove 61 is divided into a first slide rail 611 and a second slide rail 612 by the guide block 62. When the support part 2 is close to the disassembly part 4, the slider 53 slides along the first slide rail 611. When the support part 2 is away from the disassembly part 4, the slider 53 slides along the second slide rail 612.
[0034] By setting a groove 61 and a guide block 62 on the base plate 1, the groove 61 is divided into a first slide rail 611 and a second slide rail 612, realizing the sliding path control of the slider 53 at different stages. When the support part 2 is close to the disassembly part 4, the slider 53 slides along the first slide rail 611, causing the rotating seat 22 to gradually rotate, so that the insert plate 41 can be smoothly inserted between the sealing ring and the valve; when the support part 2 is away from the disassembly part 4, the slider 53 slides along the second slide rail 612, causing the rotating seat 22 to rotate in the opposite direction and return to the initial state. This design not only improves the automation level of the device, but also ensures the smoothness and reliability of the disassembly process, further improving the performance and service life of the device.
[0035] It is important to note that, to facilitate the smooth transition of slider 53 between the first slide rail 611 and the second slide rail 612, the bottom surface height of the inlet 6121 of the second slide rail 612 is lower than the bottom surface height of the first slide rail 611, and the bottom surface height of the outlet 6122 of the second slide rail 612 is higher than the bottom surface height of the first slide rail 611.
[0036] By cleverly designing the bottom height of the slide 61, the sliding process of the slider 53 is further optimized. The bottom height of the inlet 6121 of the second slide 612 is lower than that of the first slide 611, while the bottom height of the outlet 6122 of the second slide 612 is higher than that of the first slide 611. This height difference design allows the slider 53 to naturally guide the rotation of the rotary seat 22 during sliding, without the need for additional power or complex control mechanisms. This design not only simplifies the structure of the device but also improves the smoothness and reliability of operation, reduces the risk of failure caused by the slider 53 jamming or slipping, and further enhances the automation and efficiency of the device.
[0037] The working process of this device is described in detail below: First, place the valve with the sealing ring to be removed on the rotating seat 22, ensuring the valve is stable and accurately positioned. At this time, the rotating seat 22 is located on the support base 21 and is connected to the support base 21 through the angle conversion part 5. The angle conversion part 5 includes a support rod 51, a slide rod 52, and a slider 53. The slider 53 is located in the slide groove 61 on the base plate 1. The slide groove 61 is divided into a first slide rail 611 and a second slide rail 612 by the guide block 62.
[0038] The drive unit 3 is activated, and the drive motor 31 pushes the support base 21 along the guide groove 11 toward the disassembly unit 4 via the drive screw 32. During the movement, the slider 53 slides along the first slide rail 611. Since the height of the second slide rail 612 is higher than that of the first slide rail 611, the slider 53 slides smoothly within the first slide rail 611. As the support base 21 moves, the end of the insert plate 41 gradually contacts the valve, and as the valve moves forward, the insert plate 41 gradually changes from an obtuse angle to an acute angle. During this process, the head of the insert plate 41 gradually inserts into the gap between the valve and the sealing ring, and drives the sealing ring to disengage from the valve.
[0039] After the sealing ring is removed, the drive unit 3 reverses its operation, and the drive motor 31 pushes the support base 21 away from the disassembly unit 4 along the guide groove 11 via the drive screw 32. Since the inlet 6121 of the second slide rail 612 is lower than the first slide rail 611, the slider 53 begins to enter the second slide rail 612. At this time, the slide rod 52 and the support rod 51 drive the rotating seat 22 to rotate 180 degrees relative to the support base 21 until the support base 21 returns to its initial position. This rotational action ensures that the rotating seat 22 can be correctly aligned during the return process, preparing for the next operation.
[0040] Once the support base 21 returns to its initial position, the drive unit 3 restarts, pushing the support base 21 to slide along the first slide rail 611, completing the disassembly process of the sealing ring on the other side of the valve. This process is repeated to ensure that the sealing rings on both sides of the valve can be disassembled efficiently and accurately.
[0041] This process is repeated to ensure that the sealing rings on both sides of the valve can be removed efficiently and accurately. Through this automated and precise control design, this device not only improves the efficiency and reliability of sealing ring removal but also significantly reduces the difficulty and labor intensity of operation.
[0042] The above description is only a preferred embodiment of this embodiment and is not intended to limit this embodiment. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this embodiment should be included within the protection scope of this embodiment.
