Air valve as protection from water hammer
Sedlmajer, Jakub ; Machů, Tomáš (referee) ; Himr, Daniel (advisor)
The thesis deals with air valves, focusing on vacuum air valves. The theoretical part describes basic water hammer theory, especially low pressure problematics. Subsequently there are briefly explained any of usual water hammer protections, air valves function principles and differences in vacuum air valves constructions. The work is finished by measurement which evaluates reduction of pressure head according to use of this kind of protection.
