ABSTRACT:
This invention relates to structure for preventing icing in fluid valves such as gate valves, the gate of which is movable inside a chamber. Obstacles formed with orifices therein communicate with the chamber, intercept the flow of fluid through the valve and create a continuous circulation of fluid in the chamber thereby preventing any accumulation of water therein which is liable to freeze and cause the valve mechanism to seize up.
