Abstract

The invention provides a valve maintenance method and an experiment method and system for determining optimal maintenance parameters, and belongs to the technical field of valve maintenance. The experimental method comprises the following steps: determining the optimal impurity removal time of a cleaning solution by observing the impurity removal effect of the old sealing ring in the soaking process of the cleaning solution; determining the first minimum sealing damage time of the cleaning solution and the second minimum sealing damage time of the lubricating grease by observing the structural damage condition of the new sealing ring in the soaking process of the cleaning solution and the lubricating grease; and on the basis of the optimal impurity removal time and the first minimum sealing damage time, first optimal soaking time is optimized, the second minimum sealing damage time is determined as second optimal soaking time, and the first optimal soaking time and the second optimal soaking time are determined as optimal maintenance parameters of the oil and gas pipeline valve. The method is safe, reliable, high in operability and capable of guaranteeing the integrity of valve maintenance in the production and operation process of a pipeline transportation enterprise.

Description

technical field [0001] The present invention relates to the technical field of valve maintenance, in particular, to an experimental method for determining the optimal maintenance parameters of oil and gas pipeline valves, an experimental system for determining the optimal maintenance parameters of oil and gas pipeline valves, and a method for determining the optimal maintenance parameters of oil and gas pipeline valves. Maintenance method. Background technique [0002] During the storage and transportation of oil and gas pipelines, valves are needed to control the flow and cut-off of oil or gas, but the valves need to be maintained regularly after long-term use, otherwise leakage, leakage, etc. will easily occur, and even cause The fire threatens the life and property safety of staff and surrounding residents. [0003] At present, there is no complete set of valve maintenance technology in terms of valve maintenance and construction of long-distance oil and gas pipelines. ...
