Description

Reinforced pipeline connecting pipe

Technical Field

The invention relates to the field of pipeline equipment, in particular to a reinforced pipeline connecting pipe.

Background

The pipeline is commonly used for conveying liquid and gas, is an essential device for daily life, factory production operation and water source energy transmission of people, and is mainly used for water supply, water drainage, heat supply, gas supply, long-distance petroleum and natural gas transmission, agricultural irrigation, hydraulic engineering and various industrial devices. The pipeline is generally produced in a subsection manner, the length of each section of pipeline is limited, and the sizes of pipe fittings produced according to different purposes and conveying amounts are different, so that when the pipeline is conveyed far away, a plurality of pipelines with different lengths and different thicknesses are required to be connected together through a connecting device; or when it is necessary to branch off the liquid/gas being transported, it is also necessary to connect the thinner branch pipes to the thicker main pipe. The common pipe connection modes at present are two general types: firstly, a metal pipeline connector is adopted, two ends of the connector are spiral pipe openings, two pipelines are respectively in threaded connection with two ends of the connector, the butt joint of the pipelines can be generally completed in the connection process, and a layer of leakage-proof adhesive tape is generally wrapped at the pipe opening of the pipeline in the connection process; and secondly, the pipeline connecting pipe and the pipe fitting are both made of plastics or rubber materials, the outer wall of the pipe orifice and the inner wall of the pipeline connecting pipe are directly melted, then the pipe orifice is inserted into the pipeline connecting pipe, and the pipe joint is cooled naturally. However, the conventional pipe connection device still has the following problems:

1. although the mode of adopting threaded connection is relatively convenient to install, the connection part is easy to loosen when the pipeline is used for a long time or under the action of external force, so that the problems of water leakage, even pipeline falling and the like occur.

2. The existing mode of butt joint can guarantee the leakproofness through melting the pipeline, but can't dismantle the pipeline, causes very big inconvenience to dismantling the pipeline or laying the pipeline work again.
