Description

Technical Field

[0001] The invention relates to the technical field of pipeline connectors, in particular to a pipeline connector for petroleum mining. Background Art

[0002] A connector is a device that connects two pipe joints. A head is a temporary part of the pipe, leaving a pipe opening for the next construction to prevent insufficient use. A patch is a repair and sealing of the connected pipe heads. A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid flows from the high pressure part of the pipeline to the low pressure part after being pressurized by a blower, compressor, pump and boiler. It can also be conveyed by the pressure of the fluid itself or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial devices. In the oil extraction and transportation pipeline, the sealing effect of the connector used in oil extraction is not very good, and it is often corroded, which greatly affects the service life of the connector. Since the output of oil is generally unstable, it often increases or decreases suddenly. However, some connectors now have poor pressure stabilization and pressure resistance effects, and are very likely to rupture under sudden high pressure. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings and problems existing in the prior art and to propose a pipeline connector for oil mining.

[0010] Preferably, a mounting seat is provided at the lower end of the elliptical shell, and the elliptical shell is fixedly connected to the mounting seat.

[0011] The invention has a simple structure and is easy to operate. The two opposite ends of the two oil pipes to be connected are respectively inserted into the connecting pipe, and the insulator is threadedly connected to the electric heating column so that the electric heating column and the conductive block are butted against each other. Then, the power supply wire is connected to electricity, and the electric heating column and the electric heating ring are powered on and heated to a certain temperature to melt the hot melt material. Then, the hot melt material flows into the connecting pipe through the through hole and contacts the oil pipe. When the hot melt material fills the gap between the oil pipe and the connecting pipe, the power supply is disconnected, the heating is stopped, and the hot melt material is allowed to cool naturally. In this way, the oil pipe and the connecting pipe can be fixedly connected and sealed. When the oil passes through the connector, if it encounters a sudden high pressure, the flexibility and deformation ability of the hose can be slightly expanded, thereby relieving the pressure and preventing rupture. The invention has a reasonable structure, is easy to operate, has a very good sealing effect, is corrosion-resistant, and has good voltage stabilization and pressure resistance to prevent rupture.
