A shock-absorbing throat for mud-water balance shield mud circulation system

Abstract

The invention provides a compensator for a slurry balance shield mud circulation system. The compensator comprises an inner rubber layer, a first body enhancement layer, a second body enhancement layer, a skeleton layer, a third body enhancement layer, a fourth body enhancement layer, flange pieces and connector enhancement layers, wherein the first body enhancement layer, the second body enhancement layer, the skeleton layer, the third body enhancement layer, the fourth body enhancement layer are sequentially arranged from the outer circular face of the inner rubber layer outwards, and the flange pieces and the connector enhancement layers are arranged at the two ends of the inner rubber layer. The connector is sequentially provided with the first flange piece, the first connector enhancement layer, the second flange piece, the second connector enhancement layer, the third flange piece, the third connector enhancement layer, the fourth flange piece and the fourth connector enhancement layer in the axial direction, wherein the first connector enhancement layer and the first body enhancement layer are integrally arranged, the second connector enhancement layer and the second body enhancement layer are integrally arranged, the third connector enhancement layer and the third body enhancement layer are integrally arranged, and the fourth connector enhancement layer and the fourth body enhancement layer are integrally arranged. The first connector enhancement layer and the second connector enhancement layer are integrally arranged on the outer circle side of the flange pieces, and the third connector enhancement layer and the fourth connector enhancement layer are integrally arranged on the outer circle side of the flange pieces. The compensator is high in strength.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a shock-absorbing throat for a shield machine. Background technique [0002] Shock-absorbing throat is mainly used for the connection of pipelines. It is a hollow rubber product that acts as a flexible connection between metal pipelines. It can compensate for pipeline installation errors and eliminate pipeline vibration. The shock-absorbing throats on the market are all rubber die-casting. When subjected to axial tension, the deformation is large, and there is even a serious problem that the rubber body is pulled off from the movable flange. [0003] At present, shock absorbing throats are mainly used on waterways, and have low requirements for wear resistance. The shock-absorbing throat used for the mud-water balance shield mud circulation system pipeline must have strong resistance to axial tension and high wear resistance, and this type of shock-absorbing throat cannot me...
