FIELD: machine building.SUBSTANCE: valve for control of fluid medium flow under pressure along the pass leading from restricted space includes a valve body with a flow passage through it, a rupture disk in the valve body, which is bent in backward direction, in a commonly blocked position in relation to fluid medium flow through the passage, and a randomly actuated device located on the valve body near convex surface of the disk. The disk has a bent central section mainly representing a convex surface and a concave side. Convex surface faces fluid medium under pressure. The device brought into action is provided with possibility of being ruptured without puncture of the disk to initiate reverse direction and rupture of the disk and to provide fluid medium flow under pressure through the passage. There is a version of the design of such a valve, as well as a control method of fluid medium flow, which involves the same valve.EFFECT: providing control of fluid medium flow under pressure from restricted space with possibility of reducing excess pressure state; providing fluid medium flow through the valve in response to pressure reduction command.19 cl, 19 dwg |
