FIELD: production of stop valves. ^ SUBSTANCE: invention relates to production of stop valves and is intended for controlling liquid flows. The independent quarter-turn outlet three-way valve incorporates an inlet channel located between two outlet channels arranged perpendicular to the inlet channel lengthwise axis making a T-like arrangement. One of the independent valves, a central, is axially aligned with the tubular inlet channel that makes a lengthwise section of the said T-like arrangement. Another side valve has an axis perpendicular to lengthwise axis of one of the tubular outlet valves. The outlet channels make a crosswise section of the said T-like arrangement. Both valves are arranged in a single assembly unit making the three-way valve assembly part. Liquid forced into the central valve from below is distributed in ether side or in both at a time, as required. Central valve plug (3) incorporates a straight inner channel (4) and an L-shape channel with perpendicular outlets. Straight channel (4) passes liquid in both outlet channels at a time. L-shape channel allows liquid to flow in one direction only towards outlet channel (6). This is where side valve (6) is fitted in. ^ EFFECT: simple design and lower cost. ^ 2 cl, 9 dwg |
