detailed description

In the present invention, the inlet, outlet and sewage pipeline of the filter separator are combined into a header, and then through a transparent glass container with a lamp and a self-sealing sampling joint, the oil samples at the inlet, outlet and bottom of the filter separator are realized in a closed state. The advanced process supervision solves the safety hazards of increased labor intensity and jet fuel leakage caused by frequent oil sampling and pouring during process supervision and sampling.

The main principle of the integrated sampling device of the present invention is shown in FIG. 2 . The filter separator integrated sampling device is composed of inlet sampling ball valve 1, bottom sampling ball valve 2, outlet sampling ball valve 3, oil sample observer 4, confluence ball valve 5, sewage ball valve 6 and oil sample test bottle 7, of which oil sample observer 4 is used Supervise the oil sample process in a closed state. When the visual observation is qualified, close the confluence ball valve 5, connect the oil sample test bottle 7 to the oil sample observer 4, and open the inlet sampling ball valve 1, the bottom sampling ball valve 2, and the outlet in sequence. Sampling ball valve 3 just can finish the test sampling to filter separator inlet, bottom and outlet. If the oil sample in the oil sample test bottle 7 is not tested for physical and chemical indicators, the inlet sampling ball valve 1, the bottom sampling ball valve 2, the outlet sampling ball valve 3 and the sewage discharge ball valve 6 can be closed, the oil sample observer 4 can be connected, and the confluence ball valve 5 can be opened. Push the piston inwardly to deliver the sample in the oil sample test bottle 7 to the pipeline at the bottom of the filter separator. It can be seen that through the effective combination of the oil sample observer 4 and the oil sample test bottle 7, the sampling of the filter separator inlet, bottom and outlet is conveniently realized, and the process sampling and test sampling can be completed in a closed state, improving The convenience and safety of sampling work are improved.

The oil sample observer 4 is made of transparent toughened glass, and has a threaded joint matched with the pipeline and a self-sealing joint matched with the oil sample test bottle 7 . Considering that the light inside the pump room of the ship and the gas station may be dark, a local LED light is set on the upper part of the oil sample observer 4 to clearly observe the state of the internal oil sample.
