Abstract

The invention discloses an intelligent flow automatic control instrument, which integrates an intelligent controller, an electric actuating mechanism, a flow transmitter, a flow regulating valve, a pressure transmitter, a valve body and a communication technology and has functions of self-inspection and self-diagnosis. The intelligent flow automatic control instrument compares a flow set value with a flow value detected by the flow transmitter, opens the flow regulating valve when the detected flow value is inconsistent with the set value, and automatically regulates the flow to the set value. The intelligent flow automatic control instrument is particularly suitable for automatic control in industries with strict requirements on flow such as oil field, chemical industry, water treatment and mining. The intelligent flow automatic control instrument can realize interconnection and intercommunication of instruments and equipment, reduces the labor intensity, and improves the automation level and the intelligentization level of application fields.

Description

technical field [0001] The invention relates to an intelligent flow automatic control instrument, which is especially suitable for automatic control of oil field, chemical industry, water treatment, mine and other industries which have strict requirements on flow. Background technique [0002] An intelligent flow automatic control instrument is mainly composed of a flow collection and display part, a flow control part, a pressure collection part, a data collection and processing part, a data transmission part and a power supply system. Strength, improve the level of automation and intelligence in the application field. Several existing technologies are introduced below: [0003] Chinese patent CN201320540747 discloses an intelligent flow controller, including an electromagnetic flowmeter, a flow regulating valve, and an electric actuator. The current signal output terminal of the control circuit board is connected with the RS485 digital signal, and the output signal of the...
