Parameter selection and calculation system for control valves

A parameter selection and calculation system for control valves comprising:

• a server connected to a user input device, the server including a processor and a memory;
• the processor serving to process the required operations of the system;
• and the memory serving to store the software and data used in the system;
• a plurality of functional units being performed by the server;
• the functional unit comprising:
• a user selection interface connected to the user input device;
• the user selection interface performs related operations according to the contents from the user input device;
• a file manage unit connected to the user selection interface for generating a plurality of control valve design files;
• one control valve design file containing one or a plurality of control valve specification table;
• one control valve specific table being related to design of a control valve of a specific form;
• the control valve specification tables for control valves of similar forms being stored in one control valve design file instead of being stored in various different files;
• a numerical input unit connected to the user selection interface;
• the numerical input unit including a control valve design database which stores a plurality of historical data related to the control valve design parameters for different kinds of control valves;
• the numerical input unit serving for receiving the data about the building of control valve parameter tables;
• the control valve parameter table having the data about the parameters of a control valve to be designed;
• and
• a control valve logic operation unit connected to the numerical input unit;
• the control valve logic operation unit having operation logics;
• by the control logic therein and he contents in the control valve parameter table in the numerical input unit, the control valve logic operation unit forming a control valve specification table;
• and the control valve specification table having the data for making a control valve;
• the control valve specification table being transferred to the file manage unit for forming the control valve design files.
