Nut dedicated to explosion-proof equipment

Abstract

The invention discloses a nut dedicated to explosion-proof equipment. The nut comprises a nut body, wherein a through threaded hole is formed in the center of the nut body; an insulating material is sprayed on the inner side wall of the threaded hole; the outer side of the nut body is a side edge wall; the side edge wall and the upper and lower ends of the nut body are coated with an explosion-proof material; the explosion-proof material comprises the following chemical components by mass percent: 0.5 to 0.7% of aluminum, 0.05 to 0.15% of copper, 0.1 to 0.2% of zinc, 0.15 to 0.25% of manganese, 0.15 to 0.3% of chromium and 0.05 to 0.1% of potassium; and a high temperature resistant adhesive is further added inside the explosion-proof material. The nut can adapt to explosion-proof machinery, not only can be used for fastening of the explosion-proof machinery but also can be perfectly combined with explosion-proof mechanical equipment, and has explosion-proof property.

Description

technical field [0001] The invention relates to the field of nuts, in particular to a special nut for explosion-proof equipment. Background technique [0002] Nuts are parts that tightly connect mechanical equipment. Nuts and bolts of the same specification can be connected together through internal threads. Nuts and bolts are detachable connections. Nuts are used in many mechanical equipment. However, ordinary nuts are only used as ordinary fasteners and do not have explosion-proof characteristics. Special nuts are also used to fasten parts on explosion-proof mechanical equipment, and ordinary nuts do not have explosion-proof characteristics. When connecting with explosion-proof mechanical equipment Finally, the explosion-proof safety of explosion-proof mechanical equipment is reduced. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a special nut for explosion-proof equipment, which can be adapted to explosion...
