Abstract

The invention relates to a rupture disk fatigue tester for 400MPa gas cylinders, which is used for testing the durability of the rupture disks. The tester comprises a control system and a testing system, wherein the control system is used for controlling the testing system to carry out test and the testing system comprises a drive loop, a first high-pressure loop and a second high-pressure loop. The tester realizes regulating the controlled cycling pressure, cyclic frequency, pressure holding time and continuous pressure cycling by utilizing the control system to control the reducing valve, so that the data are accurately processed, thus improving the reliability of the whole system, ensuring stable work and reducing the maintenance work.

Description

technical field [0001] The invention relates to the field of bursting disc durability tests, in particular to a bursting disc fatigue testing machine for a 400MPa gas cylinder. Background technique [0002] The bursting disc is a pressure sensitive element that can quickly move (rupture or fall off) due to overpressure when the pressure of the gas cylinder rises due to an abnormal increase in the ambient temperature, and release the overpressure medium in the cylinder. The pros and cons of its quality play a particularly important role in safe production, so whether users, manufacturers or testing institutions want to understand and master the reliability of the bursting disc quality in a short period of time, they must rely on the bursting disc durability test device, However, there is currently no ideal device for testing it. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bursting disc fatigue testing machi...
