Description

Technical Field

[0001] The utility model relates to the technical field of sealing ropes, in particular to a quartz fiber sealing rope core structure. Background Art

[0002] Quartz fiber sealing rope core is a special sealing material, mainly woven from quartz fiber. Quartz fiber has excellent properties such as high temperature resistance, corrosion resistance, and wear resistance. Therefore, quartz fiber sealing rope core has good sealing performance in harsh environments such as high temperature, high pressure, and strong corrosion. Quartz fiber sealing rope core is usually used in occasions that require high sealing performance, such as seals, fillers, and gaskets in the fields of petrochemicals, electric power, aerospace, etc. It can effectively prevent the leakage of liquids, gases, steam and other media to ensure the normal operation and safety of the equipment.

[0003] Existing quartz fiber sealing ropes are mostly composed of a quartz fiber braided layer and an internal expansion core. However, the structure of the quartz fiber braided layer and the expansion core inside the existing quartz fiber sealing rope is mostly a direct wrapping type. It is inconvenient to ensure the installation and sealing strength of the expansion core after high-temperature expansion, and it is also inconvenient to protect the expansion core from waterproofing and moisture. For this reason, we propose a quartz fiber sealing rope core structure. Utility Model Content

[0007] Preferably, the sealing rope body also includes steel wire strips wound around the outer ends of the quartz fiber ropes, and the number of the steel wire strips is multiple groups.

[0008] Preferably, the sealing rope body further comprises an elastic edge arranged on one side of the outer braided sleeve outside the high-temperature expansion core, and the thickness of the elastic edge is smaller than the thickness of the outer braided sleeve.

While ensuring that the two sides of the sealing rope body are pressed tightly after installation, the sealing effect after the expansion of the outer side can also be ensured. At the same time, the inner waterproof sleeve arranged on the inner end surface of the outer braided sleeve can also provide waterproof and moisture-proof protection for the internal high-temperature expansion core and the rear high-temperature expansion strip, thereby avoiding the problem of corrosion after installation;

[0021] Specifically, the quartz fiber sealing rope core is a special sealing material, which is mainly woven from quartz fibers. Quartz fibers have excellent properties such as high temperature resistance, corrosion resistance, and wear resistance. Therefore, the quartz fiber sealing rope core has good sealing performance in harsh environments such as high temperature, high pressure, and strong corrosion. The quartz fiber sealing rope core is usually used in occasions requiring high sealing performance, such as seals, fillers, and gaskets in the fields of petrochemicals, electric power, aerospace, etc. It can effectively prevent the leakage of media such as liquids, gases, and steam to ensure the normal operation and safety of the equipment; the high-temperature expansion core 103 in the sealing rope body 100 and the multiple groups of rear high-temperature expansion strips 104 at the rear end thereof are divided into In particular, the elastic edges 108 on both sides and one end can expand in a high-temperature environment after installation. While ensuring that the two sides of the sealing rope body 100 are pressed tightly after installation, the sealing effect after the expansion of the outside can also be ensured. At the same time, the inner waterproof sleeve 102 arranged on the inner end face of the outer braided sleeve 101 can also provide waterproof and moisture-proof protection for the internal high-temperature expansion core 103 and the rear high-temperature expansion strip 104, thereby avoiding the problem of corrosion after installation.

[0022] The working principle and use process of this utility model:

[0023] After the sealing rope body 100 is installed in the sealing groove during use, the high-temperature expansion core 103 and the rear high-temperature expansion strip 104 at the front and rear ends of the sealing rope body 100 will expand under a high-temperature environment. After the expansion of the multiple groups of rear high-temperature expansion strips 104 at the rear end, while compressing the multiple groups of quartz fiber ropes 106 in the installation cavity 105 between the rear high-temperature expansion strips 104, the sealing rope body 100 will be tightened as a whole in the sealing groove, thereby ensuring the tightness of the sealing rope body 100 after installation. After the expansion of the high-temperature expansion core 103 at the front end, it will squeeze the inner waterproof cover 102 and the elastic edge 108 on the outside, and then fit tightly to the outer connecting component to ensure good sealing after installation.
