Vibration reduction connecting device for flanges based on particle damping

Abstract

The invention relates to a vibration reduction connecting device for flanges based on particle damping. The vibration reduction connecting device comprises a group of connecting flanges, a fixing pipe fitting, a fixing box body, a plurality of locking bolts and first damping particles, wherein the group of connecting flanges are fixedly connected to the ends of corresponding workpieces correspondingly; the fixing pipe fitting is arranged on the outer sides of the group of connecting flanges in a sleeving mode, a fixing gasket arranged between the group of connecting flanges in a cushioned mode is fixedly connected to the middle of the inner side wall of the fixing pipe fitting inwards, and a plurality of fixing grooves corresponding to flange holes of the connecting flanges are formed in the positions, on the two sides of the fixing gasket, of the fixing pipe fitting correspondingly; the fixing box body is detachably mounted in the fixing grooves; the locking bolts penetrate through a connecting pipe of the fixing box body, the flange holes of the connecting flanges and first through holes of the fixing gasket correspondingly and then are locked through corresponding locking nuts; and the fixing box body is filled with the first damping particles. According to the vibration reduction connecting device, on the basis that the connecting stability of the connecting flanges is not affected, the vibration reduction effect of the connecting ends of the connecting flanges can be effectively and greatly improved.

Description

technical field [0001] The invention relates to a vibration-damping connection device for flanges based on particle damping, which can be effectively installed in cooperation with the locking flange used for workpiece connection, and can effectively reduce vibration at the joint part of the workpiece while improving the locking effect Effect. Background technique [0002] Flanges are commonly used locking connectors for pipe fittings, rods, columns and other workpieces. Form a clamping lock, so as to effectively connect the workpieces that need to be docked stably into a whole. [0003] Since the connection between the flanges is a rigid connection, it is conducive to the transmission of vibration, so that the vibration of the workpiece at one end is easily transmitted to the workpiece at the other end. For some special working conditions, vibration reduction treatment is often required at the flange connection end. For example, the liquid outlet pipe connected to the out...

AI Technical Summary

Problems solved by technology

For example, the liquid outlet pipe connected to the outlet of the water pump through the flange, the vibration from the water pump is easily transmitted to the liquid outlet pipe through the flange connection end, which not only causes the vibration to spread, but also easily leads to the installation stability of the liquid outlet pipe. The design requirements are not met, resulting in frequent leakage problems at the connection nodes of the liquid outlet pipe

However, due to the special structure of the flange, it is extremely difficult to carry out effective vibration reduction treatment.

At present, most of the vibration damping methods of flange connection ends are only damping gaskets between the flanges. In order to ensure the stability of the connection, the connection force between the flanges often forms a rigid extrusion on the vibration damping gaskets. Therefore, the damping effect of the damping gasket between the flanges is basically useless
