Device for testing static and dynamic fatigue strength of valves built on the basis of disk springs

摘要

testing device for static and dynamic fatigue strength valves constructed based on hard disk springs, characterised by the fact that is built with the sleeve supporting tissues (1), and in the middle of the sliding pin is placed (2) on which is mounted wewnu0119t rzny ring piston (5), to which the outer ring is fallen piston (4),which is attached in the nest (3) supporting tissues cores (1), at the przesuwnym shank (2) is installed in the disk valve with a protective disc, and the anchoring screw cap (6).
