Wear-resistant and leakage-proof type compensator

Abstract

The invention discloses a wear-resistant and leakage-proof type compensator. The wear-resistant and leakage-proof type compensator structurally comprises a compensator body, a corrugated pipe, flanges, a flow guide tube, a pull rod, a valve, nuts, flexible seal rings and butyronitrile rubber pads. The corrugated pipe is arranged in the middle of the compensator body. The flow guide tube is arranged in the middle of the corrugated pipe. The valve is arranged at the side part of the corrugated pipe. The flanges are arranged at the two ends of the compensator body. The middles of the flanges areconnected with the pull rod. The two sides of the pull rod are connected through the nuts. The side parts of the flanges are provided with the flexible seal rings. The periphery of the outer side of each flexible seal ring is provided with the corresponding butyronitrile rubber pad. The interiors of the flanges are provided with an inner pipe. The two ends of the inner pipe are provided with precise filtering nets. Fastening pieces are distributed at the side parts of the precise filtering nets. According to the wear-resistant and leakage-proof type compensator, the compensator body is efficiently sealed while being connected, the danger due to leakage is avoided, safety and reliability are achieved, assembly and disassembly are convenient, middle gas or liquid is filtered, and wear resistance and corrosion resistance are achieved.

Description

technical field [0001] The technical field of compensator equipment of the present invention is specifically a wear-resistant and leak-proof compensator. Background technique [0002] Compensators are also customarily called expansion joints, or expansion joints. It consists of a bellows (an elastic element) that constitutes its main body and accessories such as end pipes, brackets, flanges, and conduits. Belongs to a compensation element. Utilize the effective expansion and contraction deformation of the bellows of its working body to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, or compensate the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration reduction. It is widely used in modern industry. In heating, in order to prevent the pipe from being deformed or damaged due to thermal elongation or temperature stress when...

AI Technical Summary

Problems solved by technology

[0003] The sealing performance of the existing compensator is poor, which may lead to leakage or even danger during use, and it is difficult to control the opening and closing of the compensator, and the existing compensator cannot filter the internal gas and liquid, so it is difficult to meet the current requirements. Some compensators need to be used
