Instant plug pipe device on production line and method thereof

Abstract

The invention relates to an instant plug pipe device on a production line and a method thereof, aiming to avoid the defects that when a system pipeline is replaced in the past, the pressure of fluid in the system pipeline is needed to be reduced in the first place, or a source is closed so as to prevent fluid leakage in the replacement process. The working method of the invention is used for carrying out system pipeline modification or replacement on the basis of not influencing the operation of the production line and avoiding working safety accidents and is mainly characterized in that a position is selected on an old system pipeline, then at least one short pipe is welded, and each short pipe is provided with a gate valve for regulating or interrupting the fluid of the short pipes; then the system pipeline is put on a drilling machine through a line, and a communicated hole is drilled on the system pipeline by a specially-made cutter; and then the system pipeline is processed to ensure that the inner diameters of the short pipes confirm to the inner diameter of the system pipeline for specially-made plugs to be arranged in intersection points of the system pipeline and short pipelines to finish sealing pipelines which are planned to be sealed by the system.

Description

Technical field [0001] The present invention relates to an instant pipe plugging device and method on a production line, and particularly refers to the need to reduce pressure or shut off fluid when performing system pipeline leakage prevention and modification and replacement actions, and plugs can be used to remove old pipelines If the two ends are closed, or the system needs to be modified to remove the bottleneck of the pipeline, it can be helpful to use a new return pipe to connect, so that the system pipeline can operate normally, and the action is fast and thorough, which can save the time and action of system pipeline replacement, and improve its use Efficacy is an improvement in the processing method of the online plug tube. Background technique [0002] It is generally known that when the system pipeline needs to be bottlenecked or is relatively old, the original pipeline or the old pipeline must be replaced, but before replacing the system pipeline, because the system ...

Problems solved by technology

[0002] It is generally known that when the system pipeline needs to be debottlenecked or is relatively old, the original pipeline or the old pipeline must be replaced, but before the system pipeline is replaced, because the system pipeline, the circulating For pressurized liquids such as water, diesel, gasoline, LPG, etc., and gases such as air, nitrogen, low-pressure steam or oil and gas, etc., the pressure must be reduced first or the fluid in the system pipeline must be closed to prevent the replacement process. The medium explosion pressure is released, or it must be filled with other fluids (such as nitrogen or water) to neutralize the fluid in the tube before it can be replaced. In this way, not only the production line will be interrupted, but also the procedures are complicated, time-consuming and laborious; If fluid leaks when replacing the system pipeline, it will not only pollute the environment, but if the leaked gas and liquid are poisonous, the scope of harm is not limited to human beings! Have to be careful! On the premise of not affecting the operation of the production line and construction safety, how to install a new system pipeline in advance for some parts that may already have abnormal or old pipelines so that the fluid in the pipeline can be changed to a new return pipe for circulation. The old pipeline is plugged again to block the flow of the fluid in the pipe in this section. It is not necessary to close the source of the system pipeline. Not only will the production line not be interrupted, but the safety of using the system pipeline can be improved. I believe It is the goal that the relevant industry is eager to achieve
