Parameter selection and calculation system for control valves

摘要

A parameter selection and calculation system for control valves has a file manage unit for integrating and storing the files generated in operation. In that, the control valve specification table for control valves of similar forms can be stored in one control valve design file instead of being stored in various different files. Furthermore, a language selection unit provides the function that a user can select a desire language for operating. Moreover, a user can enter into a numerical input unit for inputting related design parameters for a specific control valve or getting related design parameters by selected proper control valve forms in the control valve design database. Then these data are formed as control valve parameter tables acceptable by the control valve logic operation unit. Then the control valve logic operation unit will operate to get a control valve specification table by using the control valve parameter tables.

1. 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.
