Abstract
The flow blocking valve has retractable closing element for sealing channels carrying a fluid. This valve is used especially for controlling flow or dangerous fluids such as, for example, uranium hexafluoride. The sealing efficiency is comparable to the sealing efficiency in vacuum plants. No special production precision is necessary in its making. The valve housing is not deformed in use and this eliminates risk of damage due to friction and flexible sealing components. The actuating mechanism moves the closure unit completely out of the flow path by a lever mechanism with outwards swinging links on both sides of the actuating spindle. The levers (13, 16) are pivoted forming a toggle arrangement which pushes the valve closure plates against the sealing seats.
