FLOW SELECTOR

摘要

manufacture of fittings; equipment of transport pipe lines; seam pressure maintenance systems in oil production. SUBSTANCE: flow selector has body with inlet and outlet cylindrical branch pipes located on both sides, detachable seats and shut- off member with drive shaft. shut-off member is provided with cylindrical and taper sectional and guides located coaxially. Through passage for drive shaft is made on cylindrical section. Detachable seats are provided with taper mounting areas. Middle portion of body on section of radial inlet branch pipe is located eccentrically relative to outlet cylindrical branch pipes. Fitted rigidly on drive shaft is eccentric bush kinematically linked with slide block which is received by flow-through passage of shut-off member perpendicularly to axis of drive shaft. Guides are received by reducing branch pipes connected with outlet cylindrical branch pipes. EFFECT: enhanced operational reliability and reduced labor consumption. 2 dwg
