Embodiment 1
[0024] Example 1, such as figure 1 As shown, a method for metering and adjusting refined oil products according to the embodiment of the present invention, the method includes:
[0025] Step 1, the refined oil enters the process pipeline 2 through the inlet of the process pipeline 2, and enters the flow metering adjustment pipeline 4 through the first process valve 3 imported upstream;
[0026] Step 2, filter the refined oil and eliminate air bubbles through the filter air eliminator 5 installed on the flow metering adjustment pipeline 4;
[0027] Step 3, through the integrated temperature transmitter 7 and the intelligent pressure transmitter 8 installed on the flow measurement adjustment pipeline 4 to detect the temperature and pressure of the refined oil;
[0028] Step 4, measure the flow rate of the refined oil through the flow meter 9 installed on the flow measurement adjustment pipeline 4;
[0029] Step 5, adjusting the flow rate of the refined oil through the flow reg...

The invention discloses a metering and adjusting method for product oil. The method comprises the following steps that product oil enters a flow metering and adjusting pipeline; a filter getter device performs filtering and removes air bubbles; an integrated temperature transmitter and an intelligent pressure transmitter detect the temperature and pressure; a flowmeter meters the flow; a flow adjusting valve adjusts the flow; a reflux pipeline performs a reflux operation; a loading operation is performed; a blow-down pipeline performs blowing down; and a flow metering signal, a pressure measuring signal, a temperature measuring signal and a flow adjusting and monitoring signal are connected to the flow controller and are then transmitted to an SCADA system. The method disclosed by the invention has the beneficial effects that the method can realize real-time metering and adjustment of the flow of a loading pipeline and has the advantages of being high in accuracy, stable in operation, small in occupied area, high in integration level and favorable to maintenance and repair in the future.
Description
technical field [0001] The invention relates to the technical field of vehicle loading systems, in particular to a method for measuring and adjusting refined oil. Background technique [0002] In the loading metering station, in order to meet the normal operation of the loading system, it is necessary to measure and adjust the flow of oil products. In the past, the metering system and the regulating system were mainly set up separately. The two systems are relatively independent. Among them, the metering system mainly includes upstream and downstream straight pipe sections, upstream shut-off valves and flow meters, and the regulating system mainly includes upstream shut-off valves and regulating valves. The metering system and The data of the pressure regulating system is uploaded to the station control system, and the station control system realizes the detection and adjustment of the flow. However, the disadvantages of this method are that the flow meter and the control v...
