Abstract

The invention discloses a product oil loading metering adjusting device. One end of a process pipeline is connected to a first flange, and the other end of the process pipeline is connected to one end of a flow metering adjusting pipe via a first process gate valve; the other end of the flow metering adjusting pipe is connected to one end of a loading crane pipe through a flange; the other end of the loading crane pipe is connected to the top of a product oil vehicle top; the flow metering adjusting pipe is connected to a flow controller through a cable; a filtering air removing device, a second process gate valve, an integrated temperature transmitter, an intelligent pressure transmitter, a flow meter, a flow adjusting valve, and a triple offset butterfly valve are successively connected to the flow metering adjusting pipe in series; the flow meter, the intelligent pressure transmitter, the integrated temperature transmitter, and the flow adjusting valve are connected to the flow controller through instrument cables; and the flow controller is connected to an SCADA system. The beneficial effects of the invention are that the metering device and the adjusting device are integrated, and the metering and adjusting precision is improved.

Description

technical field [0001] The invention relates to the technical field of loading systems, in particular to a metering and adjusting device for loading 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 regulating...
