FIELD: machine building.SUBSTANCE: contact plate for a mass-transfer column contains the plate blade for reception of liquid flow, and the named plate blade has a set of holes for passing through them of rising steam and a set of valve covers. Each named valve cover is installed above one of the named respective holes and has the central section located at a distance from the named plate blade and above the respective hole, and, at least, one guide vane passing in the lateral direction and downwards from the named central section towards the named plate blade for deflection, at least, of a part of steam rising through the respective hole towards the named plate blade. At least, some of the named valve covers have pairs of legs passing from opposite ends of the named central section towards the named plate blade and pair of panels. Each named panel passes between one of respective named pairs of legs and the named guide vane for deflection of a part of steam rising through the respective hole towards the named plate blade.EFFECT: simplicity of design of the valve plate and ease of its installation on the plate, increase of plate productivity.31 cl, 15 dwg |
