Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to a spring-loaded sealing ring for high-cleanliness applications. Background Technology

[0002] In filling machinery used in the food, beverage, and pharmaceutical industries, pistons are required to drive mechanical movement. To ensure that the liquid being filled does not leak from the gap between the piston and the piston sleeve, and to prevent external impurities from entering the liquid, a spring-loaded sealing ring is needed for high-cleanliness applications to seal and protect the piston. The spring-loaded sealing ring is used for piston sealing to achieve precise filling in the filling machinery.

[0003] A search revealed Chinese patent publication number CN207715737U, which discloses a cryogenic spring energy storage sealing ring, comprising a sealing outer ring and a metal O-ring disposed within the sealing outer ring. The sealing outer ring has a U-shaped cross-section and two forked clamps. A groove with an opening facing outward is formed between the opposite sides of the two clamps. The metal O-ring is embedded in the groove of the sealing outer ring. Each of the opposite surfaces of the two clamps of the sealing outer ring forms one or more annular grooves along the circumference of the metal O-ring. After being compressed, the cryogenic spring energy storage sealing ring forms a sealing surface on both sides of the annular grooves, thereby creating a multi-stage sealing effect. This reduces the impact of microscopic unevenness on the sealing surfaces of the valve body and valve seat on the valve sealing performance, extends its sealing performance and lifespan, and also provides better wiping ability. However, because the sealing ring of this device is U-shaped, there is a gap between it and the spring. In actual use, material residue is easily caused in the sealing ring spring cavity, creating dead corners that are difficult to clean. This makes it unsuitable for high-cleanliness applications and reduces the practicality of the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a spring-loaded sealing ring for high-cleanliness applications. It aims to improve the existing technology where the sealing ring is U-shaped and has a gap between it and the spring. In actual use, the sealing ring and spring cavity are prone to material residue and have hard-to-clean dead corners, making it unsuitable for high-cleanliness applications and reducing the practicality of the device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spring-loaded sealing ring for high-cleanliness applications, comprising a piston, an installation groove on the right end of the outer wall of the piston, a sealing body slidably connected to the outer side of the installation groove, a spring cavity inside the sealing body, a stress spring inside the spring cavity, an upper lip fixedly connected to the outer right side of the spring cavity, a lower lip fixedly connected to the inner right side of the spring cavity, an anti-loosening disc fixedly connected to the right side of the upper lip and the lower lip, a protective mechanism provided on the right side of the anti-loosening disc, the protective mechanism reinforcing the spring cavity and the anti-loosening disc.

[0006] Through the above technical solution: the sealing body is installed on the mounting groove to prevent displacement of the sealing body position. When not subjected to abnormal external pressure, the stress spring is in a certain initial state, providing a certain preload force to the sealing body. Under the action of the stress spring, the upper and lower lips are adhered to the corresponding sealing surfaces, playing a sealing role and preventing leakage of internal and external media. When the external pressure increases, the external media applies pressure to the sealing body. This pressure is transmitted to the stress spring in the spring cavity, and the stress spring is compressed. As the stress spring is compressed, it generates a greater elastic force, pushing the upper and lower lips to adhere more tightly to the sealing surfaces. The anti-loosening disc prevents the sealing body from moving, ensuring the stability of the sealing structure. Moreover, the spring cavity is formed by the sealing body and the anti-loosening disc being fixedly connected to form a sealing cavity, with no dead corners for cleaning and disinfection, and no risk of residue contaminating the filling material.

[0007] As a further description of the above technical solution:

[0008] The protective mechanism includes a baffle plate, which is attached to the right side of the outer wall of the anti-loosening disc. A support ring 1 is fixedly connected to the left side of the outer wall of the baffle plate. The outer wall of the support ring 1 has multiple reserved holes. A support ring 2 is fixedly connected to the right side of the outer wall of the piston. The right side of the outer wall of the support ring 2 has multiple threaded holes. A plurality of bolts are provided on the left side of the outer wall of the baffle plate. All of the bolts pass through the multiple reserved holes and are threadedly connected to the corresponding threaded holes.

[0009] The above technical solution involves bolts passing through pre-drilled holes and then threadedly connecting them to threaded holes, allowing the baffle to be firmly fixed to the piston. In the operating environment, the piston and baffle clamp the anti-loosening disc via bolt connection, preventing the spring energy storage ring from moving during operation in high-cleanliness applications, thereby improving its service life. The clamped anti-loosening disc, piston, and baffle form a sealing pair, providing an additional seal compared to a standard cross-section spring energy storage sealing ring, thus enhancing the sealing capability.

[0010] As a further description of the above technical solution:

[0011] The anti-loosening disc has a first reinforcing rib inside, and a second reinforcing rib is fixedly connected to the outside of the first reinforcing rib. The size of the first reinforcing rib is larger than that of the second reinforcing rib.

[0012] Through the above technical solution, the reinforcing ribs 1 and 2 inside the anti-loosening disc further enhance the strength of the anti-loosening disc, so that the anti-loosening disc is in an open state.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the baffle has multiple circular grooves on the right side, and the outer wall of the multiple bolts fits into the inner wall of the circular grooves on the right side. The outer wall of the multiple bolts also has cross grooves on the right side.

[0015] The above technical solution ensures that the outer wall of the bolt fits into the circular groove, preventing the bolt from being exposed and affecting the operation of the device. The cross groove facilitates the use of tools to tighten or loosen the bolt.

[0016] As a further description of the above technical solution:

[0017] The piston has hexagonal seats fixedly connected to both the upper and lower sides of its outer wall, and each of the two hexagonal seats has a threaded groove on its inner wall.

[0018] Through the above technical solution: the hexagonal seat provides a connection point for other external connectors, and the threaded groove ensures that the external connectors are firmly connected to the hexagonal seat.

[0019] As a further description of the above technical solution:

[0020] The outer diameter of the first support ring is equal to the inner diameter of the anti-loosening disc, and the first support ring is slidably connected to the anti-loosening disc.

[0021] Through the above technical solution, the support ring can slide flexibly within the inner diameter range of the anti-loosening disc, which not only maintains the connection with the anti-loosening disc, but also avoids the generation of additional stress due to excessive constraint of the anti-loosening disc by the protective mechanism, thereby preventing damage to the components due to stress concentration and other problems.

[0022] As a further description of the above technical solution:

[0023] The outer wall of the baffle has multiple threaded grooves on the left side, and the outer wall size of the multiple bolts is the same as the inner wall size of the threaded grooves.

[0024] With the above technical solution, when the bolt is screwed into the second thread groove, due to the consistency of the dimensions, the threads can fully mesh, so that the bolt will not easily loosen or come out when subjected to external force.

[0025] As a further description of the above technical solution:

[0026] The diameter of the first support ring is equal to the diameter of the reserved hole, and both the first support ring and the second support ring are engaged with the anti-loosening disc.

[0027] The above technical solution involves the engagement of support ring one and support ring two with the anti-loosening disc, which plays a crucial role in positioning and initial fixation.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, when the sealing body is placed in the appropriate position of the installation groove and is not subjected to abnormal external pressure, the stress spring provides a certain pre-tightening force to the sealing body. At this time, the upper lip and lower lip clamp the stress spring and are connected together with the anti-loosening disc to ensure the stability of the sealing structure. The spring cavity is formed by the sealing body and the anti-loosening disc being fixedly connected to form a sealing cavity. There are no dead corners for cleaning and disinfection, and there is no risk of residue contaminating the filling material.

[0030] 2. In this utility model, the bolt passes through the reserved hole and is then threaded to the threaded hole, so that the baffle can be firmly fixed on the piston. In the equipment operating environment, the piston and the baffle clamp the anti-loosening disc through the bolt connection, preventing the spring energy storage ring in high-cleanliness applications from moving during the operation, thereby improving the service life. The clamped anti-loosening disc, piston and baffle form a sealing pair, which has an extra seal compared to the standard cross-section spring energy storage sealing ring, thereby improving the sealing ability.

[0039] 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.

[0040] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of a spring-loaded sealing ring for high-cleanliness applications, comprising a piston 1. A mounting groove 3 is formed on the right end of the outer wall of the piston 1, serving as the mounting base for the sealing ring. The mounting groove 3 provides an installation position for a sealing body 4. The sealing body 4 is slidably connected to the outside of the mounting groove 3. The sealing body 4 is made of PTFE material, possessing self-lubricating properties to reduce sliding friction and achieve precise filling. A spring cavity 5 is formed inside the sealing body 4, providing space for a stress spring 6. The stress spring 6 is housed inside the spring cavity 5. The stress spring 6 deforms according to the pressure. If the external pressure increases, the stress spring 6 is compressed, generating greater elastic force, causing the sealing body 4 to fit more tightly against the sealing surface to maintain a good sealing effect. When the external pressure decreases, the stress spring 6 rebounds, maintaining a certain sealing pressure. An upper lip 7 is fixedly connected to the outside of the right side of the spring cavity 5, and a lower lip 8 is fixedly connected to the inside of the right side of the spring cavity 5. The upper lip 7 and the lower lip 8 serve to fix the stress spring 6. On the one hand, it serves a sealing function. An anti-loosening disc 9 is fixedly connected to the right side of the upper lip 7 and the lower lip 8. The anti-loosening disc 9 is machined from PTFE tubing. Connecting the upper lip 7 and the lower lip 8, the anti-loosening disc 9 stabilizes their relative positions. The spring cavity 5 is formed by the sealing body 4 and the anti-loosening disc 9, creating a sealed cavity. There are no dead corners for cleaning and disinfection, eliminating the risk of residue contaminating the filling material. A protective mechanism 2 is provided on the right side of the anti-loosening disc 9, reinforcing the spring cavity 5 and the anti-loosening disc 9. The interior of the anti-loosening disc 9 contains reinforcing ribs. 10. A second reinforcing rib 11 is fixedly connected to the outer side of the first reinforcing rib 10. The size of the first reinforcing rib 10 is larger than that of the second reinforcing rib 11. The first reinforcing rib 10 and the second reinforcing rib 11 inside the anti-loosening disc 9 further enhance the strength of the anti-loosening disc 9, so that the anti-loosening disc 9 is in an open state. Hexagonal seats 14 are fixedly connected to the upper and lower sides of the outer wall of the piston 1. The inner walls of the two hexagonal seats 14 are provided with threaded grooves 15. The hexagonal seats 14 provide connection points for other external connecting parts. The threaded grooves 15 can ensure that the external connecting parts are firmly connected to the hexagonal seats 14.

[0041] Specifically, the sealing body 4 is installed through a sliding connection with the mounting groove 3 on the right end of the outer wall of the piston 1. Because the sealing body 4 is self-lubricating, it reduces sliding friction during installation, facilitating precise placement of the sealing body 4 into the appropriate position in the mounting groove 3. When not subjected to abnormal external pressure, the stress spring 6 is in a certain initial state, providing a certain preload to the sealing body 4. At this time, the upper lip 7 and lower lip 8, under the action of the stress spring 6, adhere to the corresponding sealing surfaces, achieving a sealing effect and preventing leakage of internal and external media. When the external pressure increases, the external media applies pressure to the sealing body 4. This pressure is transmitted to the stress spring 6 in the spring cavity 5, causing the stress spring 6 to compress. As the stress spring 6 compresses, it generates greater elastic force, pushing the upper lip 7 and lower lip 8 to adhere more tightly to the sealing surfaces. The upper lip 7 and lower lip 8 are connected together by the anti-loosening disc 9. During equipment operation, due to possible vibrations, pressure fluctuations, etc., the upper lip 7 and lower lip 8... There is a tendency for relative displacement. The anti-loosening disc 9 can limit this relative displacement, stabilize the relative position of the upper lip 7 and the lower lip 8, and ensure the stability of the sealing structure. The spring cavity 5 is formed by the sealing body 4 and the anti-loosening disc 9. There are no dead corners for cleaning and disinfection, and there is no risk of residue contamination of the filling material. The reinforcing ribs 10 and 11 set inside the anti-loosening disc 9 further enhance the strength of the anti-loosening disc 9, so that the anti-loosening disc 9 is in an open state. The hexagonal seat 14 provides connection points for other external connecting parts. The threaded groove 15 can ensure that the external connecting parts are firmly connected to the hexagonal seat 14.

[0042] Reference Figure 1 , Figure 3 and Figure 4The protective mechanism 2 includes a baffle 201, which is attached to the right side of the outer wall of the anti-loosening disc 9. The baffle 201 provides direct protection, preventing external damage to the anti-loosening disc 9 and the spring cavity 5, preventing collisions with foreign objects, and blocking direct impacts from some liquids. A support ring 1 202 is fixedly connected to the left side of the outer wall of the baffle 201. The outer diameter of the support ring 1 202 is equal to the inner diameter of the anti-loosening disc 9 for positioning. Multiple pre-drilled holes 203 are provided on the outer wall of the support ring 1. A support ring 204 is fixedly connected to the right side of the outer wall of the piston 1. Multiple threaded holes 205 are provided on the right side of the outer wall of the support ring 204. Multiple bolts 206 are provided on the left side of the outer wall of the baffle 201, and all bolts 206 pass through the multiple pre-drilled holes 203. The corresponding threaded hole 205 is threaded. When installing the protective mechanism 2, the bolt 206 passes through the reserved hole 203 and is then threaded to the threaded hole 205, so that the baffle 201 can be firmly fixed on the piston 1. The connection stability between the protective mechanism 2 and the piston 1 is ensured by the cooperation of the first support ring 202 and the second support ring 204. Multiple circular grooves 12 are opened on the right side of the outer wall of the baffle 201. The right side of the outer wall of multiple bolts 206 fits against the inner wall of the circular groove 12. The outer wall of the bolts 206 fits against the circular groove 12 to prevent the bolts 206 from being exposed and affecting the operation of the device. A cross groove 13 is opened on the right side of the outer wall of multiple bolts 206. The function of the cross groove 13 is to facilitate the use of tools to tighten or loosen the bolts 206.

[0043] Specifically, the baffle 201 is attached to the right side of the outer wall of the anti-loosening disc 9. Its main function is to provide direct protection. The bolt 206 passes through the reserved hole 203 and is then threaded into the threaded hole 205, so that the baffle 201 can be firmly fixed to the piston 1. In the equipment operating environment, the anti-loosening disc 9 is clamped by the piston 1 and the baffle 201 through the connection of the bolt 206, preventing the spring energy storage ring in high-cleanliness applications from moving during operation, thereby improving its service life. The clamped anti-loosening disc 9, piston 1 and baffle 201 form a sealing pair, which has an extra seal compared to the standard cross section spring energy storage sealing ring, thereby improving the sealing capacity. The outer wall of the bolt 206 is attached to the circular groove 12 to prevent the bolt 206 from being exposed and affecting the operation of the device. The function of the cross groove 13 is to facilitate the use of tools to tighten or loosen the bolt 206.

[0044] Reference Figure 1 , Figure 2 and Figure 6The outer wall of the baffle 201 has multiple threaded grooves 16 on its left side. The outer wall size of the multiple bolts 206 is the same as the inner wall size of the threaded grooves 16. When the bolts 206 are screwed into the threaded grooves 16, due to the consistency of size, the threads can fully engage, so that the bolts 206 will not easily loosen or come out when subjected to external force. The diameter of the support ring 202 is equal to the diameter of the support ring 204. Both the support ring 202 and the support ring 204 are engaged with the anti-loosening disc 9. During the process of installing the protective mechanism 2 onto the piston 1... In this process, the interlocking relationship plays a crucial role in positioning and initial fixation. The outer diameter of the support ring 202 is equal to the inner diameter of the anti-loosening disc 9. The support ring 202 is slidably connected to the anti-loosening disc 9. When the anti-loosening disc 9 moves slightly in the axial or radial direction due to the reciprocating motion of the piston 1, the support ring 202 can slide flexibly within the inner diameter range of the anti-loosening disc 9. This maintains the connection with the anti-loosening disc 9 and avoids additional stress caused by excessive constraint of the anti-loosening disc 9 by the protective mechanism 2, thereby preventing damage to the components due to stress concentration and other problems.

[0045] Specifically, when bolt 206 is screwed into thread groove 16, the threads can fully engage due to the consistency of dimensions, so that bolt 206 will not easily loosen or come out when subjected to external force. Through the engagement of support ring 202 and support ring 204 with anti-loosening disc 9, this engagement plays a crucial role in positioning and initial fixation. Support ring 202 can slide flexibly within the inner diameter range of anti-loosening disc 9, which not only maintains the connection with anti-loosening disc 9, but also avoids additional stress caused by excessive constraint of anti-loosening disc 9 by protective mechanism 2, thereby preventing damage to components due to stress concentration and other problems.

[0046] Working Principle: The sealing body 4 is installed on the mounting groove 3 to prevent displacement of the sealing body 4. Due to the self-lubricating properties of the sealing body 4, sliding friction can be reduced during installation, making it easy and accurate to place the sealing body 4 into the appropriate position in the mounting groove 3. When not subjected to abnormal external pressure, the stress spring 6 is in a certain initial state, providing a certain preload to the sealing body 4. At this time, the upper lip 7 and lower lip 8 are adhered to the corresponding sealing surfaces under the action of the stress spring 6, playing a sealing role and preventing leakage of internal and external media. When the external pressure increases, the external media applies pressure to the sealing body 4. This pressure is transmitted to the stress spring 6 in the spring cavity 5, and the stress spring 6 is compressed. As the stress spring 6 is compressed, it generates a greater elastic force, pushing the upper lip 7 and lower lip 8 to adhere more tightly to the sealing surface. The upper lip 7 and lower lip 8 are connected together by the anti-loosening disc 9. During equipment operation, the anti-loosening disc 9 can limit the displacement of the upper lip 7 and lower lip 8, stabilizing the upper lip 7. The relative position of the lower lip 8 ensures the stability of the sealing structure. The spring cavity 5 is formed by the sealing body 4 and the anti-loosening disc 9, which are fixedly connected to form a sealed cavity. There are no dead corners for cleaning and disinfection, and there is no risk of residue contamination of the filling material. The bolt 206 passes through the reserved hole 203 and is then threadedly connected to the threaded hole 205, so that the baffle 201 can be firmly fixed on the piston 1. In the equipment operation environment, the anti-loosening disc 9 is clamped by the piston 1 and the baffle 201 through the bolt 206, which prevents the spring energy storage ring from moving during the operation in high-cleanliness applications, thereby improving the service life. The clamped anti-loosening disc 9, piston 1 and baffle 201 form a sealing pair, which has an extra seal compared to the standard cross-section spring energy storage sealing ring, thereby improving the sealing capacity.
