Problems solved by technology
[0002] Bolts within the scope of strong acid chemical plants are vulnerable to strong corrosive environments, and strong corrosiveness is attached to the bolts through the air, especially between the nut of the bolt and the connection between the equipment and between the nut and the protruding bolt head One end is particularly susceptible to corrosion, and it will be rusted quickly, thereby reducing the service life, and the bolt is a fixed and solid part, once corroded, its function is easily affected, causing the connected equipment to loosen and the perforation to expand. Aging, it is easy to cause the equipment fixed by bolts to loosen or even fall off, and the consequences are very serious

Embodiment Construction
[0013] like figure 1 As shown, a special mechanism for bolt protection in a strong corrosive environment includes two transparent insulating seals arranged on the upper and lower sides of the bolt. The two transparent insulating seals are respectively an upper transparent insulating seal 1 and a lower transparent insulating seal 2. The two ends of the block transparent insulating seal are provided with snap-in mechanisms 3, and the gaps between the bolts, nuts 4 and nuts 5 and the fixed equipment are provided with glass fiber brushes 6.
[0014] Utilizing the present invention, two upper and lower transparent insulating seals are arranged at the part where the bolt is connected with the fixed equipment, the two ends of the two transparent insulating seals are provided with snap-in mechanisms 3, and the gaps in the middle are provided with densely covered glass fiber brushes 6, which realizes The external protection of the bolts effectively reduces the amount and circulation of...

The invention discloses a special mechanism for protecting a bolt in a strong corrosive environment and a use method. The special mechanism comprises two transparent insulating seals arranged on the upper part and the lower part of the bolt, the two transparent insulating seals comprise an upper transparent insulating seal and a lower transparent insulating seal, wherein two ends of the two transparent insulating seals are provided with clamping mechanisms, and glass fiber brushes are arranged among gaps between a nut of the bolt and fixed equipment. According to the invention, the upper and lower two transparent insulating seals are arranged at a connecting part between the bolt and the fixed equipment, two ends of the two transparent insulating seals are provided with the clamping mechanisms, middle gaps are provided with the dense glass fiber brushes, and thus, the outer protection of the bolt is realized, and the amount and the circulating amount of strong corrosive gas in contact with the bolt are effectively reduced; in addition, the glass fiber brushes can be bonded together after in long-term contact with the external strong corrosive gas, so that the contact between the strong corrosive air and the bolt is better blocked, and the transparent insulating seals are beneficial to the master of a corrosion condition of the bolt.
Description
technical field [0001] The invention belongs to the technical field of hardware protection, and in particular relates to a special mechanism for bolt protection in a strong corrosion environment and a use method thereof. Background technique [0002] Bolts within the scope of strong acid chemical plants are vulnerable to strong corrosive environments, and strong corrosiveness is attached to the bolts through the air, especially between the nut of the bolt and the connection between the equipment and between the nut and the protruding bolt head One end is particularly susceptible to corrosion, and it will be rusted quickly, thereby reducing the service life, and the bolt is a fixed and solid part, once corroded, its function is easily affected, causing the connected equipment to loosen and the perforation to expand. Aging can easily cause the equipment fixed by bolts to loosen or even fall off, and the consequences are very serious. Contents of the invention [0003] The i...
