<p>PURPOSE: A pipe break valve device is provided to be produced with a reduced number of components and to guarantee the stable action permanently. CONSTITUTION: A pipe break valve device comprises a housing, a valve slide(18), and a throttling device. The housing has an inlet connection part for pipes(14) and an outlet connection part for flexible pipes(54). In a normal operational state of a valve slide, flowing media pass through the housing. When pipes are broken or leaked, the valve slide is displaced in a direction opposite to the action of an elastic unit(22) in order to isolate the pipe break valve device. The throttling device has an internal space(20) connected to a throttling duct(28) and the inside of the housing at an inlet and an outlet through the throttling duct.</p> |
