Abstract

The invention relates to the technical field of valve assembly and testing, in particular to a ball valve dynamic characteristic parameter test system and test method. The ball valve dynamic characteristic parameter test system comprises a hardware control system for a ball valve dynamic characteristic parameter test and a software control system based on virtual instrument programming. As a carrier and an execution part of virtual instrument software, the hardware control system completes action including test medium automatic switching, test medium pressure and flow automatic adjusting, servo motor drive ball valve opening degree automatic adjusting and the like. The software system adopts a programming mode based on a virtual instrument, and is used for pressure data acquisition and data pre-processing, flow data acquisition and data pre-processing, test medium temperature data acquisition and data pre-processing, ball valve dynamic characteristic parameter automatic analyzing and saving, and characteristic parameter curve real-time displaying. Through the coordination of the hardware system and the software system, the invention achieves the automatic test and analysis of two types of dynamic characteristic parameters which are opening degree, pressure, flow and temperature characteristics of a ball valve and a dead zone characteristic.

Description

technical field [0001] The invention relates to the technical field of valve assembly testing, in particular to a ball valve dynamic characteristic parameter testing system and testing method. Background technique [0002] As a kind of actuator, valve is an indispensable control equipment in various fields such as petroleum, chemical industry, power station, long-distance pipeline, shipbuilding, nuclear industry, various cryogenic engineering, aerospace and marine oil production. Among them, ball valves, as a main type of valves, are being used in various industries at home and abroad. [0003] Ball valve refers to a valve that uses a valve stem to drive a ball with a circular through hole as an opening and closing member, and rotates around the ball valve axis. It is mainly used to open and close pipelines and equipment media, and can also be used for fluid regulation and control. The performance testing of ball valves mainly includes strength performance testing, sealing ...
