And the phenomena of loosening, dislocation and the like of the packing ring in use are prevented.

Description

Technical Field

[0001] This utility model relates to the technical field of packing installation, and in particular to a combined packing structure. Background Technology

[0002] Structurally, packing rings are ring-shaped and made of various materials woven or molded. Common materials include graphite, aramid fiber, asbestos, and various types of rubber, each giving the packing ring unique properties. Packing rings are installed at sealing points in equipment, such as valves and pipe connections. During equipment operation, they fit tightly against the sealing surface, using their elasticity and material properties to fill tiny gaps, thereby preventing the leakage of liquids, gases, and other media. Their excellent sealing performance not only ensures efficient equipment operation and reduces energy waste but also prevents the leakage of hazardous substances, protecting the working environment. They play an irreplaceable role in many industries, including petrochemicals, power, and machinery manufacturing.

[0003] Currently, installing multiple packing rings requires more precise operation and higher installation skills. Improper installation can easily lead to uneven gaps between the packing rings, thus affecting the sealing effect. Furthermore, the installation process for multiple packing rings is relatively complex and increases installation time.

[0004] Currently, no effective solution has been proposed to address the problem of uneven gaps between multiple packing rings in related technologies, which affects the sealing effect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a combined packing structure to solve the problem of uneven gaps between multiple packing rings that affect the sealing effect.

[0017] A first docking element is disposed at the top of the first mounting element;

[0020] The second mounting element is disposed at the bottom end of the main body unit and connected to the main body unit;

[0021] The second docking element is disposed at the bottom end of the second mounting element and is connected to the second mounting element;

[0022] The second connecting element is disposed outside the second docking element and is detachably connected to the first mounting unit of the other combined packing structure.

[0023] In some embodiments, the combined packing structure further includes:

[0024] At least one locking unit is provided, which passes through the first mounting unit, the main body unit and is connected to the second mounting unit, respectively, for limiting the position of the first mounting unit and the second mounting unit.

[0036] This utility model discloses a combined packing structure that connects two adjacent main units (packing rings) through the cooperative use of a first mounting unit and a second mounting unit. During installation, the relative positions of the packing rings are defined, effectively avoiding uneven gaps caused by manual installation errors. This results in uniform resistance for the sealing medium as it passes through the packing rings, reducing the risk of leakage from larger gaps and improving overall sealing performance. When subjected to medium pressure, the load is evenly distributed among the packing rings through the mounting units, preventing excessive wear or damage to individual packing rings due to uneven stress, further enhancing the reliability and stability of the entire sealing system and ensuring long-term safe operation of the equipment. A locking unit securely fixes the first and second mounting units to the main units, forming a tight and stable integrated structure from multiple packing rings. This connection method effectively resists the influence of axial forces, radial forces, and vibrations generated during equipment operation, preventing loosening or misalignment of the packing rings during use and extending the service life of the packing ring assembly.
