FIELD: machine building.
SUBSTANCE: device for manual adjustment of the amount of flowing substance of steam lines includes a throttle housing having an inlet and an outlet. Piston is located eccentrically in the throttle housing and provided with possibility of being rotated about its longitudinal axis. The above piston has the possibility of being brought into action by means of at least one gripping element outside the throttle housing. An eccentric longitudinal drilled hole is made in the above piston. The piston is installed in the eccentrically located drilled hole inside the throttle housing. The piston has running slots to admit O-rings, which are located on the side of the end face. Cross section of the main line is decreased to the specified cross section after rotation through the specified angle. Besides, the amount of flowing substance is kept at minimum level in each position of the piston.
EFFECT: creation of compact device at simplifying the design and low maintenance expenses.
