Abstract

The invention discloses a valve debugging and diagnosis integration device and an analysis method. The integration device comprises a sensor, a transmitter unit, a data acquisition and processing unit, a control and analysis unit, a monitoring and operation unit, a driving unit and a system power supply. According to the invention, installation and debugging after the maintenance can be performed on four kinds of valves like electric switch valves, electric adjusting valves, pneumatic switch valves and pneumatic adjusting valves; comprehensive and quantitative automatic analysis can be performed on operation performance parameters of debugged or operated valves; manufacturing, installation, maintenance and debugging quality of the valves can be checked; potential defects in the valves can be found in advance so that the defects can be eliminated in advance; the production benefit and safety in the production process are improved; meanwhile, related parameters and test steps in the debugging and operation performance parameter analysis processes are automatically stored and reports are generated, so analysis can be easily performed after a valve fails in the production processes; and in addition, by use of AI and DI channels of the device, real-time acquisition or monitoring can be performed on all kinds of physical quantity in the production processes; and the integration device has functions of a high speed recorder.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a device and method for valve debugging and performance analysis. Background technique [0002] With the development of computer technology, artificial intelligence has become the general trend. Artificial intelligence can standardize and standardize the production process, thereby reducing human errors and improving production efficiency and quality. [0003] With the development of DCS (distributed control system), the control logic control of the electric valve switching valve and the servo amplification processing part of the electric regulating valve are all realized inside the DCS. In this case, the traditional electric valve debugging method (through the valve power supply The electric valve can be debugged by the drawer cabinet) It is no longer possible to debug the electric valve, and the electric valve debugging task must be completed with the help of the electric valve...
