FIELD: mechanical engineering.
SUBSTANCE: valve of axial flow has interconnected outer and inner housings. The housings form the axially symmetrical flowing part. The inner housing receives unloaded plunger with sealing side and mechanism for its movement. The plunger is provided with welded metallic bellows. One end of the bellows is tightly secured to it. The other end of the bellows is tightly connected with the inner housing. When the bellows is compressed, it provides axial movement of the sealing side of the plunger toward the seat in the direction opposite to the direction of fluid flow.
EFFECT: enhanced reliability.
