  • Patent number: 8628117
    Abstract: The instant disclosure relates to a push-fit ring-seal joint structure for plastic pipes. For the joint structure, a lip portion tapers away from the pipe outlet, while a throat portion tapers toward the pipe outlet. The joint structure allows the angular deflection to be increased by three or four times versus the conventional push-fit joint, while maintaining excellent sealing and pressure rating. By the unique design of the joint structure, the structural flexibility of pipe connection can be increased. When there is ground movement due to land subsidence or earthquake or adjustment in pipe route, the coupled pipe can maintain excellent sealing and pressure rating. Therefore, the joint structure of the instant disclosure indeed has novelty and industrial applicability.

    Abstract: An annular sealing material seals a pipe joint between a socket and a spigot. The sealing material includes a bulb part which is composed of a first bulb, a second bulb located closer to the inner side of the socket than the first bulb, and a narrow part present between the first and second bulbs. The first bulb is pressed against the inner circumferential surface of the socket. The second bulb is pressed against the outer peripheral surface of the spigot. The second bulb is inclined towards the pipe center from the first bulb in a natural state before it is provided between the socket and the spigot. The inner diameter of the second bulb is smaller than the outer diameter of the spigot in the natural state. The second bulb is extensible in the pipe diameter direction due to elastic deformation of the narrow part.
