Dynamic Performance of High Temperature Ceramic Check
Valves. Edition No. 1
VDM Publishing House, Sep 2008, Pages: 156
This book discusses the performance of check valves
with springs and seats made of Yttria stabilized
zirconia. Standard check valves have components in
them, such as metallic springs and elastomeric seats,
which have certain limitations with respect to
temperature. The springs were of 10, 12, 14 and 16
turns per inch (TPI). This helped us study the
performance of the springs based on the coil
thickness and number of turns per inch.The tests
included deflection and cracking pressure
measurements at ambient and elevated temperatures.
The experimental data was correlated to a metal
spring equation with certain modifications to compare
the performance of the ceramic check valves.
The work was carried out at University of Alabama
Huntsville under the able guidance of Dr James E
Smith, Jr and support from Parker and Hannifin
Corporation, Valves Division, Jacksonville, Alabama
