FIELD: machine building. ^ SUBSTANCE: invention relates to quick-split high-waterproof threaded connections of pipes with screw sockets. It contains external screw thread with left and right direction of coils on end parts of connected pipes and screw thread inside screw socket the left and right direction of coils on its reciprocal sides. Inside screw socket in its middle part it is implemented as radial annular groove, in which with ability of axial movement it is installed packing washer, contacting to face surfaces of connected pipes. Screw socket is implemented in the form of two half-couplings, separated by axial plug and connected to each other by means of enveloping clutch, allowing outside engagement components for 0 - application to it of rotational moment. Enveloping clutch is connected to screw socket by means of engagement components and is installed on screw socket with ability if axial movement. ^ EFFECT: invention increases tightness. ^ 9 cl, 5 dwg |
