FIELD: hydraulic and pneumatic engineering. ^ SUBSTANCE: device has body with coaxially placed two serially opened locking organs. Coaxially to body guiding cylinder perforated with through apertures is fixed to first locking organ, placed with possible displacement relatively to guiding cylinder and interaction with saddle and stationary support. Second locking organ is made in form of decreased cope of the first one, provided with guiding cylinder, fixed to analogical cylinder of first locking organ on the side of flow output. First locking organ is made in form of hollow barrel moved along outer surface of guiding cylinder with unloading apertures in its bottom. Hollow barrel I loaded with back action spring. The latter is placed between its bottom and body. Second locking organ is loaded with back action spring, placed between its bottom and bottom of first locking organ. Saddle for first locking organ is placed on the side of flow output. Bottom of second locking organ is placed on the side of flow output. Bottom of first locking organ is connected to servo through rod. On each saddle of guiding cylinders of locking organs on the side of flow outputs protective element is placed. Protective element is in contact with front edge of barrel and is made in form of for example moveable ring spring-loaded relatively to saddle. This ring envelopes saddle and covers stationary compaction of locking couple in its open position on the side of the flow. Ring is provided with unloading apertures and limiter of movement in form of for example removable brackets. Brackets are evenly placed along circle in amount no less than three and fixed at the end of saddle. Servo is made in form of pneumatic cylinder adjuster coaxial to the body. Said cylinder is mounted outside gas flow and contains moving piston. Piston separates hollows of controlling and output pressures. In hollow of said pressure said rod connected to piston is placed. On the opposite side piston is supported by pusher. Pusher is mounted coaxially with its possible contact to sensor of position of locking organs ad coaxial to pusher of limiter of their movement, moved manually or automatically. ^ EFFECT: higher durability, broader functional capabilities. ^ 1 dwg |
