Problems solved by technology

Non-metallic expansion joints can compensate axial, transverse, and angular directions. They have the characteristics of no thrust, simplified support design, corrosion resistance, high temperature resistance, noise reduction and vibration reduction, etc., especially suitable for hot air pipes and smoke pipes, but some due to flexibility It is not very good, it does not have much impact on the reverse thrust of the equipment and system, and it cannot control its elongated length very well, so it is easy to damage

Abstract

The invention relates to a new nonmetal expansion joint, relating to a nonmetal expansion joint. The nonmetal expansion joint comprises an adapter (1), an otic placode (2), a flexible ring belt (3), a nut (4), a stud bolt (5), high alumina cellucotton (6), a honeycomb duct (7), an inner honeycomb duct (8) and a gemel. The adapter (1) is arranged at the bottom end of the otic placode (2) and vertically connected with each other. The high alumina cellucotton (6) is arranged below the flexible ring belt (3) and provided with a gemel (9). The stud bolt (5) is arranged on one side of the nut (4). The honeycomb duct (7) is arranged below the inner honeycomb duct (8). The surface of the gemel (9) is made of stainless steel wire netting and the inner layer thereof comprises silicone cloth, reinforcing fiber cloth, tetrafluoro cloth, glass fibre cloth, and compound Tianjian cloth. The gemel has good flexibility and reaction thrust influence on devices and systems, brings convenience to the pipeline design, has easy controllable tensible length and is difficult to be damaged.

Description

Technical field: [0001] The invention relates to a non-metallic expansion joint. Background technique: [0002] Non-metallic expansion joints are also called non-metallic compensators and fabric compensators, which are a kind of compensators. Its materials are mainly fiber fabrics, rubber, and other high temperature resistant materials. It can compensate the vibration of the fan and air duct operation and the deformation of the pipeline. Non-metallic expansion joints can compensate axial, transverse, and angular directions. They have the characteristics of no thrust, simplified support design, corrosion resistance, high temperature resistance, noise reduction and vibration reduction, etc., especially suitable for hot air pipes and smoke pipes, but some due to flexibility It's not very good, it doesn't have too much impact on the reverse thrust of the equipment and system, and it can't control its elongated length very well, so it is easy to damage.
