Description

technical field

[0001] The invention belongs to the technical field of valve testing, and in particular relates to a valve impact performance testing pipeline and system. Background technique

[0002] In the conventional valve test system, the usual way to adjust the volume of the cavity after the test piece is: fill the water tank with water, control the water filling volume of the water tank, and use the remaining volume in the water tank as the simulated air cushion volume. The disadvantages of this method are: : 1) The system needs to increase the water medium subsystem, and the water supply and drainage of the container need to be considered, and the system is relatively complicated; 2) The volume control is realized by liquid level control, and the accuracy is low; 3) The follow-up pipeline of the simulated air cushion has a Larger water vapor has come, affecting the accuracy and life of the system, causing potential safety hazards; 4) The volume occupied is relatively...
