Embodiment Construction

[0027] Embodiments of the telescopic flexible pipe joint of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] figure 1 A cross-sectional structure of the expandable flexible pipe joint A of this embodiment is shown, and the expandable flexible pipe joint A is composed of a first cylindrical body, a second cylindrical body, and a third cylindrical body. The first cylindrical body is made of a pair of cast iron spherical rings 1, 1 with a partially spherical outer peripheral surface 4, and the second cylindrical body 2 is inserted into the cylindrical body so that it can move relatively in the direction of the cylinder axis X. The cast iron sleeve 2 in the first cylindrical body constitutes. The third cylindrical shape is composed of a pair of cast iron sleeves 3, 3 with a spherical inner peripheral surface 5 overlaid on each outer peripheral surface 4 of the first cylindrical body and flanges as connecting parts forme...

Abstract

The present invention relates to a telescopic flexible pipe connection formed from first cylindrical body, second cylindrical body and third cylindrical body, and on the internal peripheral surface of the first cylindrical body, ring grooves are formed, and on front and rear ends in direction of its cylindrical axis, walls roughly perpendicular to said cylindrical axis are formed, and on the external peripheral surface near the end portion of second cylindrial body, a recessed portion in which locking ring is nested and fixed is formed, and when it is subjected to the action of external force, the end face of locking ring is face-contacted with the above-mentioned walls formed on the front and rear ends of first cylindrical body respectively to restrict it to move, and at the same time, in all sliding portions between first cylindrical body, second cylindrical body and third cylindrical body, sealing devices are inserted respectively.

Description

technical field [0001] The present invention relates to a telescopic flexible pipe joint, in detail, it relates to a telescopic flexible pipe joint for connecting water pipes and other pipes, which can absorb external force and prevent pipeline damage when subjected to excessive external force . Background technique [0002] The established pipelines such as long water pipelines laid on the ground or underground are often subjected to pressure, tension in the direction of the pipe axis, or shear force and bending moment in the direction intersecting the pipe axis due to ground subsidence or earthquakes. various external forces. When this force is large, the stress tends to concentrate on the pipe joints connecting the installed pipes, causing partial damage to the pipe joints. Therefore, it is necessary to be able to absorb the external force acting on the water pipe part to prevent the damage of the pipe joint. [0003] In the past, a pipe joint has been developed. In or...
