Marine fuel oil pipeline oil-leakage emergency welding device and method

Abstract

The invention relates to a marine fuel oil pipeline oil-leakage emergency welding device and method. The marine fuel oil pipeline oil-leakage emergency welding device is installed at one end of an oilleakage pipeline and structurally comprises an inlet valve, a gas buffer cabinet, a pressure reducing valve and an outlet valve which are connected in sequence, the inlet valve, the gas buffer cabinet, the pressure reducing valve and the outlet valve are connected through pipelines, the outlet valve is connected with one end of the oil leakage pipeline through a hose, and the other end of the oilleakage pipeline is further provided with a closing plate; and a first pressure gauge is arranged between the inlet valve and the gas buffer cabinet, and a second pressure gauge is further arranged between the outlet valve and the oil leakage pipeline. Through the marine fuel oil pipeline oil-leakage emergency welding device, oxygen in the oil leakage pipeline is exhausted and then welded, the situation that the oil leakage pipeline is detached, then taken to other places to be cleaned,, then welded and then reassembled is avoided, welding operation can be directly conducted on site, and a large amount of time is saved; testing can be continued on the basis of original testing, original testing data is reserved, and repeated work is avoided; and welding is carried out after the oxygen isexhausted, so that the welding safety is also guaranteed.

Description

technical field [0001] The invention relates to the field of ship pipeline construction, in particular to a device and method for emergency welding of oil leakage of marine fuel pipelines. Background technique [0002] During the construction stage of the ship, various tests are required. The main engine of the generator needs to consume fuel oil and diesel oil during operation. No matter whether it is fuel oil or diesel oil. The test can only be continued after the pipeline is disassembled for cleaning, welding, and reassembly. The complete cycle of pipeline disassembly, cleaning, welding, and reassembly takes about 2 days. Test and record; there is no problem with this method at the beginning of the test, but if the test is halfway through or more, it will take time and effort to do it again, and all the recorded data will be invalidated. welding. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a device ...
