Multifunctional threaded pipeline

Abstract

The invention provides a multifunctional threaded pipeline which comprises a first pipe body with an external screw thread, and a second pipe body with an internal screw thread. The second pipe body and the first pipe body are connected in a screwing way through the internal screw thread and the external screw thread; a main glue injection channel is built in the threaded pipe wall of the first pipe body; a branch glue injection pipeline is arranged on the threaded pipe wall of the first pipe body; and one end of the main glue injection channel communicates with the outside. The multifunctional threaded pipeline has the beneficial effects that (1) the device can be sealed by adopting a high-pressure sealant filling manner regularly without the need for disassembling the pipeline; and (2) when the connected pipeline does not need to be sealed, lubricating oil is injected into the main glue injection channel, so that two rusted pipelines can be disassembled and separated.

Description

technical field [0001] The invention designs a mechanical device, in particular a multifunctional threaded pipeline. Background technique [0002] When the pipe is connected to the pipe, it is usually used to connect with raw tape, and over time. The raw tape will oxidize, catalyze, and lose its sealing effect. In addition, the long-term corrosion of the pipeline will accelerate the failure of the raw tape. Rust is a kind of iron salt, which will accelerate the corrosion of the raw tape under the action of water, resulting in the failure of the seal of the raw tape. In addition, the pipeline needs to be disassembled during pipeline maintenance, and it is very troublesome to disassemble the rusted and adhered pipeline. Therefore, it is necessary to provide a technical solution to solve such technical problems. Contents of the invention [0003] The invention provides a multi-functional threaded pipeline. The purpose of designing and developing this device is: 1. When the...
