Description

Technical Field

[0001] This utility model relates to the field of anti-aging sealing ring technology, specifically a valve core assembly for a vehicle emergency shut-off valve with a fastening sealing ring. Background Technology

[0002] The emergency shut-off valve is installed at the bottom of the vehicle tank and is in a closed state during transportation, mainly relying on the sealing ring in the sealing seat for sealing. Due to frequent changes in the medium loaded on the tank truck, the presence of corrosive substances, temperature differences, and impurities, the sealing ring ages and cracks faster. In some cases, the sealing ring may even jump out of the mounting groove in the sealing seat, causing the emergency shut-off valve sealing ring to fail, resulting in medium leakage and posing a serious safety hazard.

[0003] In the past, when replacing the sealing ring, the old-style sealing seat would damage the sealing ring. If the inner diameter of the sealing ring was slightly too large, the sealing ring would jump out of the sealing seat groove after a period of use, affecting the normal sealing effect of the sealing ring.

[0004] To address the aforementioned issues, innovative design based on the existing component structure is urgently needed. Utility Model Content

[0005] The purpose of this utility model is to provide a valve core assembly for a vehicle emergency shut-off valve with a fastening sealing ring, in order to solve the problems mentioned in the background art, such as the sealing ring being damaged when the old-style sealing seat is replaced, and the sealing ring jumping out of the sealing seat groove after a period of use when the inner diameter of the selected sealing ring is slightly too large, thus affecting the normal sealing effect of the sealing ring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vehicle emergency shut-off valve core assembly with a fastening sealing ring, comprising a docking cylinder and an upper ring body disposed at the lower end of the docking cylinder; a lower ring body is disposed at the lower end of the upper ring body, and a sliding rod is fixedly installed at the lower end of the lower ring body; a compression ring is slidably installed on the outer side of the lower ring body, and an anti-aging outer ring is glued between the compression ring and the lower ring body, and a sealing inner ring is disposed inside the anti-aging outer ring;

[0007] A disassembly structure for controlling the rapid replacement of the anti-aging outer ring is provided between the upper ring body and the lower ring body, and a positioning structure for controlling the uniform wear of the anti-aging outer ring is provided between the upper ring body and the lower ring body.

[0008] Preferably, the disassembly structure includes a rotating shaft, which is fixedly installed at the lower end of the docking cylinder and rotatably connected to the upper ring body.

[0009] Preferably, the disassembly structure further includes a docking inner plate, which is fixedly installed inside the lower end of the upper ring body, and the docking inner plate is rotatably connected to the rotating shaft.

[0010] Preferably, a rotating inner disk is fixedly installed at the lower end of the rotating shaft, and the rotating inner disk is located inside the docking inner disk. A connecting rod is rotatably installed inside the rotating inner disk, and a pushing rod is rotatably installed at the end of the connecting rod away from the rotating inner disk, and the pushing rod is slidably connected to the docking inner disk.

[0011] Preferably, a docking outer plate is fixedly installed at the upper end of the lower ring body, and the docking outer plate is located outside the docking inner plate. A limit groove is formed inside the docking outer plate, and a return spring is provided inside the limit groove. A limit block is provided at the end of the return spring away from the limit groove, and the limit block is engaged with the docking inner plate.

[0012] Preferably, the positioning structure includes a docking groove and a docking block, wherein the docking groove is provided on the outer side of the docking outer plate, and the docking block is fixedly installed inside the upper ring body, and the docking groove and the docking block are engaged and connected.

[0013] Preferably, the positioning structure further includes a guide rod, which is fixedly installed at the lower end of the lower ring body, and the guide rod is arranged parallel to the sliding rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The engagement of the mating groove and the mating block ensures the stability of the mating between the upper and lower ring bodies. Furthermore, the engagement of the limiting block with the mating inner disc further ensures the stability of the mating between the upper and lower ring bodies. This ensures the balance of the compression ring against the compression of the aging outer ring and the sealing inner ring, thus guaranteeing the sealing effect of the component.

[0016] 2. Furthermore, by driving the rotating shaft to rotate through the docking cylinder, the inner rotating disc can move the connecting rod and the pushing rod, causing the limit block to separate from the inner docking disc, making it convenient to replace the anti-aging outer ring and the sealing inner ring;

[0017] 3. Furthermore, by connecting the outer and inner discs, the stability of the upper part of the component can be ensured, thereby ensuring the balance of pressure on the anti-aging outer ring and the sealing inner ring.

[0018] 4 Furthermore, by using sliding rods and guide rods to position the movement trajectory of the component, the wear of the sealing ring can be ensured evenly, effectively guaranteeing the sealing effect of the sealing ring. At the same time, the sealing ring structure is made of adhesive, which can prevent the sealing ring from jumping out. Attached Figure Description

[0027] 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.

[0028] Example 1: In a specific embodiment, this utility model provides the following technical solution: a vehicle emergency shut-off valve core assembly with a fastening sealing ring, such as... Figures 1-3 The basic usage process of the valve core assembly is shown in the figure.

[0029] The assembly includes a connecting cylinder 1 and an upper ring 2 at the lower end of the connecting cylinder 1; a lower ring 3 is provided at the lower end of the upper ring 2, and a sliding rod 4 is fixedly installed at the lower end of the lower ring 3; a compression ring 5 is slidably installed on the outer side of the lower ring 3; an anti-aging outer ring 6 is glued between the compression ring 5 and the lower ring 3; and a sealing inner ring 7 is provided inside the anti-aging outer ring 6.

[0030] When using the vehicle emergency shut-off valve core assembly with a fastening seal ring, the valve core assembly needs to be installed on the outside of the opening and closing interface. During installation, the sliding rod 4 and guide rod 19 need to be limited to allow the assembly to move in a directional manner and control the opening and closing of the interface channel. During operation, the anti-aging outer ring 6 needs to contact the inner wall of the opening and closing channel to control the channel closure. Figure 2 The sliding of the control rod 4 and the guide rod 19 causes the anti-aging outer ring 6 to separate from the channel, thereby completing the opening and closing process of the control channel of the component and effectively improving the stability of the component's operation.

[0031] Example 2: In one specific embodiment, such as Figures 1-5 As shown, in order to solve the problem of poor sealing after long-term use of existing sealing rings, the process of achieving stable sealing of this component is disclosed.

[0032] A positioning structure for controlling the uniform wear of the anti-aging outer ring 6 is provided between the upper ring body 2 and the lower ring body 3. The positioning structure includes a docking groove 16 and a docking block 17. The docking groove 16 is opened on the outside of the docking outer plate 12, and the docking block 17 is fixedly installed inside the upper ring body 2. The docking groove 16 and the docking block 17 are engaged and connected. The positioning structure also includes a guide rod 19, which is fixedly installed at the lower end of the lower ring body 3. The guide rod 19 is parallel to the sliding rod 4.

[0033] When using the vehicle emergency shut-off valve core assembly with a fastening sealing ring, the anti-aging outer ring 6 needs to be in contact with the inner wall of the pipe. The anti-aging outer ring 6 and the sealing inner ring 7 deform due to the compression of the compression ring 5 and the lower ring body 3. The anti-aging outer ring 6 is bonded to the compression ring 5 and the lower ring body 3 with adhesive. This ensures the stability of the anti-aging outer ring 6 and the sealing inner ring 7 during operation, preventing the sealing ring from separating from the assembly and guaranteeing the sealing effect during operation. Figure 3 Meanwhile, the guide rod 19 and the sliding rod 4 can limit the movement trajectory of the anti-aging outer ring 6 and the sealing inner ring 7, ensuring the balance of the wear degree of the anti-aging outer ring 6 and the sealing inner ring 7, avoiding the situation where excessive wear in a single position leads to poor sealing, thereby ensuring the sealing stability of the component during operation.

[0034] Example 3: Based on the above examples, such as... Figures 1-7 The process of replacing the sealing ring structure of this component is shown in the figure.

[0035] A disassembly structure for quickly replacing the anti-aging outer ring 6 is provided between the upper ring body 2 and the lower ring body 3. The disassembly structure includes a rotating shaft 8, which is fixedly installed at the lower end of the docking cylinder 1 and rotatably connected to the upper ring body 2. The disassembly structure also includes a docking inner plate 18, which is fixedly installed inside the lower end of the upper ring body 2 and rotatably connected to the rotating shaft 8. A rotating inner plate 9 is fixedly installed at the lower end of the rotating shaft 8 and is located inside the docking inner plate 18. The inner plate 9 rotates internally. A connecting rod 10 is installed, and a push rod 11 is rotatably installed at the end of the connecting rod 10 away from the rotating inner disk 9. The push rod 11 is slidably connected to the docking inner disk 18. A docking outer disk 12 is fixedly installed at the upper end of the lower ring body 3. The docking outer disk 12 is located outside the docking inner disk 18. A limit groove 13 is opened inside the docking outer disk 12. A return spring 14 is provided inside the limit groove 13. A limit block 15 is provided at the end of the return spring 14 away from the limit groove 13. The limit block 15 is engaged with the docking inner disk 18.

[0036] After using the vehicle emergency shut-off valve core assembly with a fastening seal ring for a period of time, the anti-aging outer ring 6 and sealing inner ring 7 need to be replaced. During this process, the docking cylinder 1 needs to drive the rotating shaft 8 to rotate. This allows the rotating shaft 8 to drive the rotating inner disk 9 to rotate inside the docking inner disk 18. The rotation of the docking inner disk 18 causes the connecting rod 10 to push the push rod 11, and the movement of the push rod 11 causes the limit block 15 to separate from the docking inner disk 18. Figure 6 When the limiting block 15 moves, the return spring 14 will contract. After the limiting block 15 separates from the inner plate 18, the outer plate 12 can be separated from the inner plate 18, thereby separating the upper ring 2 from the lower ring 3. This facilitates the replacement of the anti-aging outer ring 6 and the sealing inner ring 7, ensuring the convenience of replacing the anti-aging outer ring 6 and the sealing inner ring 7 of this component and increasing its overall practicality.
