High-temperature medium pressure pipeline blocking device

Abstract

The invention provides a high-temperature medium pressure pipeline blocking device which comprises a traveling mechanism, an inspecting mechanism, a blocking mechanism, a cooling mechanism and a control mechanism, wherein the traveling mechanism is arranged on an end part fixing base of a pressure pipeline; the inspecting mechanism is arranged on the traveling mechanism; the blocking mechanism isarranged on the traveling mechanism and matched with the inspecting mechanism; the cooling mechanism is arranged on the traveling mechanism; and the control mechanism is arranged on the traveling mechanism, and used for controlling the traveling mechanism, the inspecting mechanism, the cooling mechanism and the blocking mechanism. By adoption of the high-temperature medium pressure pipeline blocking device provided by the invention, not only can the online blocking operation be achieved, but also the circumstance that when a tool is utilized for treatment, slag from the side wall of a leakinghole falls and pollutes a medium in the pipeline can be avoided; meanwhile, the pipeline can be permanently or semi-permanently repaired, so that the repairing operation on the pipeline during an overhaul can be avoided and just the automatic inspecting operation is needed; and when leaking at high temperature, the pipeline can be temporarily cooled, so that the dangerous environment caused by toohigh temperature can be avoided.

Description

technical field [0001] The invention relates to the technical field of pipeline leakage sealing equipment, in particular to a high-temperature medium pressure pipeline sealing device. Background technique [0002] Pressure pipelines refer to all pipelines that are subject to internal or external pressure. However, for pressure pipelines, not only are they required to withstand high pressure, but also need to work stably for a long time, but due to the harsh working environment, it is inevitable that they will leak. The safest and safest way is to close the pressurized pipeline and then carry out maintenance, but it will seriously affect industrial production or residents' lives, so a plugging device that can be repaired online is needed. There are various plugging devices and methods, but they only perform temporary plugging, but do not achieve long-term stable plugging, or the plugging effect is not good, and there are plugging holes in the online cleaning process.

The safest and safest way is to close the pressurized pipeline and then carry out maintenance, but it will seriously affect industrial production or residents' lives, so a plugging device that can be repaired online is needed. There are various plugging devices and methods, but they only perform temporary plugging, but do not achieve long-term stable plugging, or the plugging effect is not good, and there are plugging holes in the online cleaning process. Unnecessary pollution will be generated, which will cause unnecessary pollution to the pipeline, which will inevitably limit the use of tools for the plugging device
