Abstract

The invention discloses a flange nut loose-proof sleeve. The technical essential scheme is as follows: a connecting sleeve (2) is at least fixedly connected with two nut sleeves (1); the nut sleeves (1) are sleeved in the nuts of bolts on a corresponding flange; and the connecting sleeve (2) is fixed on a fixing device (6) on a flange outer side surface(4).

Description

technical field [0001] The invention relates to an anti-loosening sleeve, in particular to a flange nut anti-loosening sleeve. Background technique [0002] Flanges are widely used in petroleum, chemical, power transmission and other fields. Once the bolts loosen, there will be unexpected serious consequences. Therefore, the requirements for the anti-loosening performance of the connecting bolts are relatively high. In the prior art, the main methods of flange connection are: 1. Apply adhesive on the thread of the bolt to prevent loosening; 2. Use self-locking nuts with self-locking function to connect the bolts to prevent loosening; 3. The method of putting on the stop pad below is anti-loosening. The above three anti-loosening methods have poor anti-loosening reliability. Contents of the invention [0003] The purpose of the present invention is to solve the defects in the above-mentioned technologies, and propose a flange nut anti-loosening sleeve with high anti-loose...
