The invention relates to a multi-layer oil curtain partition device for fast and flexible partition of vacuum pipelines. One side of the partition device is the sealed vacuum section of the vacuum pipeline, and the other side is the disassembly section of the vacuum pipeline; the partition device is equipped with There are butt flanges, which are connected to the sealed vacuum section and the dismantling section through the butt flanges; high-pressure nozzles and oil pumps are arranged above the pipelines of the partition device, and Rafal nozzles and fuel tanks are correspondingly installed below the pipelines; in addition, the high-pressure An inlet pressure regulating valve is set between the nozzle and the oil pump, and an outlet pressure regulating valve is set between the Lafal nozzle and the fuel tank; the oil pump sprays the working fluid through the high-pressure nozzle to form a jet oil curtain in the pipeline, And enter the corresponding Rafal nozzle below the pipeline; the invention realizes the vacuum pipeline partition by using the high-pressure nozzle to generate the high-speed jet oil curtain. Good adaptability.
Description
technical field [0001] The invention belongs to the field of partitioning of vacuum pipelines, in particular to the field of flexible partitioning of rapid multi-layer oil curtains of vacuum pipelines. Background technique [0002] The establishment of vacuum in the pipeline requires the continuous operation of the vacuum pump unit, and the replacement and maintenance of parts in the vacuum pipeline needs to break the balance of the entire vacuum system. Therefore, it is very necessary to realize the rapid and flexible isolation of the vacuum pipeline. Contents of the invention [0003] In order to solve the above problems, the present invention achieves the above object through the following technical solutions: [0004] A multi-layer oil curtain partition device that realizes fast and flexible partition of vacuum pipelines, one side of the partition device is the sealing vacuum section of the vacuum pipeline, and the other side is the disassembly section of the vacuum pi...
