Method for tightening connections of ram and seats of two-seat valve according to which one spring-supports with springy elements one of seats that with possibility of restricted axial displacement is tightly connected to ram, due to force prodiced with elastic elements, and due to force that is developed by pressure drop of working medium and effective area of the seat; at that deformation of elastic elements and displacement of seat within its boundaries one compensates changes of linear dimensions of parts of the valve at thermal expansion of those, this provides preservation of tightness of joints of ram and seats of twp-seat valve. |
