Novel packing ring structure

Abstract

The utility model relates to a novel packing ring structure which comprises a main body unit, a first mounting unit, a second mounting unit and a locking unit. The utility model has the advantages that: the main body unit provides a solid support foundation for the whole superposed structure by virtue of higher hardness and strength of the main body unit, so as to ensure that the superposed structure is not easy to deform under severe working conditions such as high pressure and high friction; the first mounting unit and the second mounting unit are accurately butted, so that all the main body units can be tightly connected, all layers of packing rings can be effectively aligned in the mounting process, and the sealing defect caused by mounting errors is reduced; and the overlapped main body units are locked by the locking units, so that the layers are firmly fixed into a whole. For the problems caused by thermal expansion and shrinkage differences between different layers, the stress can be effectively dispersed by the tight connection and locking mechanism. Even if a part of layers expand with heat and contract with cold, due to the fact that the units are tightly matched, the whole structure can be kept stable, and gaps cannot be generated due to local deformation.

Description

Technical Field

[0001] This utility model relates to the technical field of sealing components, and in particular to a novel packing ring structure. Background Technology

[0002] Graphite packing rings are a crucial sealing component. Made primarily of graphite, they are manufactured into a ring-shaped structure using a special weaving process. They are black in appearance and soft yet resilient in texture. In terms of performance, they possess excellent high-temperature resistance, capable of withstanding environments up to 800℃ and adapting to temperatures as low as -200℃. They exhibit excellent chemical stability, resisting the erosion of various corrosive media such as acids, alkalis, and salts. Their good self-lubricating properties effectively reduce friction and wear between the ring and equipment components. Graphite packing rings play a vital role in petrochemical reactors and pipeline valves, power industry steam pipelines and water pumps, and equipment in papermaking, shipbuilding, and other fields. They tightly fill the sealing area, preventing media leakage, ensuring stable equipment operation, preventing safety accidents and environmental pollution, and providing a solid guarantee for the continuous and efficient operation of various industries.

[0003] To increase the thickness of graphite packing rings, multiple packing rings are usually stacked together. Under high temperature conditions, graphite packing rings will thermally expand and shrink when cooled. When multiple rings are stacked together, there may be slight differences in thermal expansion and contraction between different layers, which can lead to deformation or stress concentration of the entire structure, thus affecting the sealing effect.

[0004] Currently, no effective solution has been proposed for the problem of multiple graphite packing rings stacked together in related technologies, which leads to deformation or stress concentration of the entire structure and affects the sealing effect. Utility Model Content

Precise docking of the first and second mounting units ensures a tight connection between the main units, effectively aligning the packing rings during installation and reducing sealing defects caused by installation errors. A locking unit securely locks the stacked main units, firmly fixing each layer into a unified whole. This tight connection and locking mechanism effectively disperses stress, addressing issues arising from differences in thermal expansion and contraction between different layers. Even if some layers experience thermal expansion and contraction, the tight fit between units maintains overall structural stability, preventing gaps caused by localized deformation, thus avoiding stress concentration and maintaining a consistently good sealing effect. This ensures reliable operation of the equipment under complex conditions, including high temperature, high pressure, and environments with frequent temperature fluctuations, preventing media leakage and guaranteeing production safety and stability.

[0162] Furthermore, the locking unit 40 also includes a second limiting element 42 and a control element 43.

[0173] The method of using this utility model is as follows (installation and usage instructions using two novel packing ring structures):

[0174] (I) Docking Operation

[0175] The second docking element 32 in a novel packing ring structure is docked into the third groove element 22 in another novel packing ring structure;

[0176] Twist the main component 11 in a novel packing ring structure to drive the second docking component 32 in the novel packing ring structure to rotate in the circumference of the third groove component 22 in another novel packing ring structure until the second docking component 32 in the novel packing ring structure abuts against the first docking component 23 in another novel packing ring structure.

[0177] During the process, the second snap-fit ​​element 33 in a novel packing ring structure snaps into the first snap-fit ​​element 24 in another novel packing ring structure.

[0178] Finally, the fourth through-slot element 35 in a novel packing ring structure is connected to the second through-slot element 25 and the third through-slot element 26 in another novel packing ring structure.

[0179] (II) Locking Operation

[0180] The corresponding locking element 41 is selected and passes through the first limiting element 27, the third through groove element 26, the second through groove element 25, and the first through groove element 14 in a new type of packing ring structure in sequence, and then is threadedly connected to the connecting element 34 in a new type of packing ring structure until it passes through the first limiting element 27 and the third through groove element 26 in another new type of packing ring structure.

[0181] Then, it passes sequentially through the fourth through groove element 35 in a novel packing ring structure, the second through groove element 25 in another novel packing ring structure, and the first through groove element 14, and is then threadedly connected to the connecting element 34 in another novel packing ring structure until it is tightened.

[0182] The advantages of this invention are as follows: The main unit, with its high hardness and strength, provides a solid supporting foundation for the entire stacked structure, ensuring it is not easily deformed under harsh conditions such as high pressure and high friction. Precise docking of the first and second installation units ensures a tight connection between the main units, effectively aligning the packing rings during installation and reducing sealing defects caused by installation errors. Locking units securely fix the stacked main units, firmly fixing each layer into a unified whole. This tight connection and locking mechanism effectively disperses stress, addressing issues arising from differences in thermal expansion and contraction between different layers. Even if some layers experience thermal expansion and contraction, the tight fit between units maintains overall structural stability, preventing gaps caused by localized deformation, thus avoiding stress concentration and maintaining a consistently good sealing effect. This ensures reliable operation of the equipment under complex conditions, including high temperature, high pressure, and environments with frequent temperature fluctuations, preventing media leakage and guaranteeing production safety and stability.

Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
