Hydraulic bidirectional pipeline sealing device

Abstract

The invention provides a hydraulic bidirectional pipeline sealing device, relates to the technical field of hydraulic pipeline sealing, and solves the problems that in the actual application process of an existing hydraulic pipeline, the joint of the pipeline cannot be sealed and protected when liquid flows through the pipeline, so that the joint of the pipeline is easily broken due to long-time use, and the pipeline cannot be subjected to effective shock isolation and heat insulation operation, so the pipeline cannot be effectively protected. The hydraulic bidirectional pipeline sealing device comprises a heat preservation seepage-proofing pipe, and the heat preservation seepage-proofing pipe is elastically connected to the inner position of an anti-extrusion pipe sleeve. Blades can be driven through the impact force of liquid, so that the purpose of driving a driven shaft to rotate through a transmission shaft is achieved. According to the design, an expansion disc can be driven to rotate synchronously through rotation of the blades, and therefore the purpose that arc-shaped expansion plates are thrown out and expanded through centrifugal force is achieved. By means of the design, when liquid passes through main pipe bodies, the joints of the main pipe bodies and splicing pipes can be automatically shielded and protected.

Description

technical field [0001] The invention belongs to the technical field of hydraulic pipeline sealing, and more specifically relates to a hydraulic two-way pipeline sealing device. Background technique [0002] The pipeline refers to the pipeline that transmits the working fluid in the hydraulic system. Compared with the pipeline, the pipeline is a reasonably arranged pipeline system. Because of the flexibility of the pipeline, the pipeline is often used in hydraulic systems and other liquid-driven systems. Mechanical equipment, with the rapid development of my country's hydraulic pipe market, the application and research and development of core production technologies related to it will surely become the focus of attention of enterprises in the industry. Understanding the research and development trends, process equipment, technology applications and trends of domestic and foreign hydraulic pipe production core technologies is critical for companies to improve product technical ...
