GEAR CONNECTING PIPE-LINES Russian patent published in 1999 - IPC

FIELD: space equipment, hydraulic systems, mechanical engineering. SUBSTANCE: gear connecting pipe-lines includes stationary and separable joined bodies with valves installed in them, coupling nut pit on separable body where cylindrical guide coupled to coupling nut with flange having ball lock is located. Outer surface of guide has protrusions with conical grooves, cylindrical grooves with ledges-rests and conical craters. Stationary body has flange with ball locks and cylindrical groove with grooves and ledges. Force of each ball lock of separable body exceeds that of ball lock of stationary body in agreement with relation , where F₁ is force of spring of ball lock of stationary body; F₂ is force of spring of ball lock of coupling nut; d₁ is diameter on which force of spring of ball lock of stationary body acts; d₂ is diameter on which force of spring of ball lock of coupling nut acts. EFFECT: increased reliability of connection of pipe-lines. 5 dwg
