Abstract

FIELD: valving. SUBSTANCE: valve has two movable stop members arranged in series and rods of the stop members that are axially alined one inside the other and brought out of the valve housing from one side. When the valve is closed, the members shut off the flow from the first part of the valve housing to the second part and, both in closed and in open position, form leakage space. EFFECT: improved design.

Claims (1)

С помощью двухседельного клапана должно быть выполнено требование не только к осушаемой, но и к разгружаемой от давления лекажной полости при всех рабочих режимах. Это обеспечивается тем, что выполненный в виде полого штока шток клапана второго запирающего органа с внутренней стороны ограничивает часть соединительного канала, который непосредственно примыкая к лекажной полости, на части своего дальнейшего прохождения по отношению к своей остальной части расширен до проходного поперечного сечения и увеличивает лекажную полость, образуя объем.By means of a two-seat valve, the requirement must be fulfilled not only for the drained cavity, but also for the pressure-free cavity under all operating conditions. This is ensured by the fact that the valve stem of the second locking member, made in the form of a hollow rod, on the inside limits the part of the connecting channel, which is directly adjacent to the cage cavity, is expanded to a passage cross section with respect to its rest, and increases the cage cavity forming a volume.
