Method and system for parameter optimization of long-life valve group based on big data

Abstract

The present invention relates to the field of big data processing, specifically a method and system for optimizing long-life valve group parameters based on big data. The statistical opening threshold of the flow-open valve corresponding to the working condition of the group, and then select other valve groups whose opening threshold is similar to the target valve group based on the statistical opening threshold, and obtain other valve group sets; wherein the flow-open valve opening Switch to a flow-closed valve when the opening threshold is reached; based on other valve groups in other valve group sets, obtain the ideal opening threshold for the flow-open valve to switch to the flow-close valve and the ideal opening threshold for the flow-close valve to switch to the flow-open valve After the ideal opening threshold, combined with the opening threshold of the target valve group, the opening reference interval of the flow-open valve in the target valve group is obtained, and the target valve group is determined according to the position of the opening threshold of the target valve group in the opening reference interval. The switching speed of the valve. The invention avoids excessive wear of the valve group.

technical field [0001] The invention relates to the field of big data processing, in particular to a method and system for optimizing parameters of a long-life valve group based on big data. Background technique [0002] In the production process of high-pressure valve work, the high-pressure valve group will vibrate and noise due to different loads. When the high-pressure valve vibrates, it means that the valve core, valve seat and other internal parts are severely washed away, resulting in a series of wear marks, deep grooves and pits, and some even cause the valve stem to break, which seriously affects the use of the valve. performance, reducing service life. [0003] In some high-pressure valve working processes, it is possible to use high-pressure valve groups to simultaneously use two types of valves, open and closed, to achieve simple control and wear balance while avoiding vibration.

When the high-pressure valve vibrates, it means that the internal parts such as the valve core and the valve seat are severely washed away, resulting in a series of wear marks, deep grooves and pits, and some even cause the valve stem to break, which seriously affects the use of the valve. performance, reduced service life

[0003] In some high-pressure valve working processes, high-pressure valve groups can be used to simultaneously use two types of open and closed valves to achieve simple control and wear balance while avoiding vibration. However, the calibration of valve vibration and opening ratio needs to be based on fluid characteristics. On-site calibration, and the valve pressure and flow rate are not proportional, due to factors such as pressure difference, valve section shape, valve opening, etc., the relationship between pressure and flow rate cannot be determined, resulting in difficult calibration
