Problems solved by technology

Due to the poor earthquake resistance and large deformation ability of ordinary socket-type pipe joints, the design and processing of the existing pipe seismic joints developed by Kubota Company in Japan are relatively complicated, and on-site installation is very inconvenient

Embodiment Construction

[0045] The present invention is described in detail below in conjunction with the accompanying drawings: the anti-seismic pipeline interface comprises a pipeline socket (1), a pipeline socket (2), a water-stop rubber ring (3), and a metal stop ring (4). See attached figure 1 , attached figure 2 , attached image 3 , attached Figure 4 , attached Figure 5 .

[0046] First install the rubber gasket (5) in the groove of the pipe socket;

[0047] Install the three circular arcs that make up the metal limit ring (4) in the groove of the pipe socket (1) in sequence. After the three rings are assembled into a complete ring, they can be firmly stuck on the pipe socket ( 1) in the groove;

[0048] Then install the water-stop rubber ring (3) on the raised position of the pipe socket (1);

[0049] After installing the water-stop rubber ring (3), insert the pipe socket (2) into the pipe socket (1), and apply a layer of lubricant to the water-stop rubber ring (3) and the metal sto...

Abstract

The invention discloses a socket and spigot joint pipeline anti-seismic connector, and relates to a socket and spigot joint pipeline connector so as to improve the tensile bearing force of a buried pipeline connector, optimize the anti-seismic performance of the buried pipeline, effectively reduce the earthquake disaster at the position of the pipeline connector, prolong the service life of the pipeline connector, reduce the pipeline post-disaster repairing and maintaining cost. The connector comprises five parts including a pipeline bell mouth, a pipeline inserting port, a rubber ring, a metal limiting ring and a rubber gasket. The pipeline bell mouth is internally provided with an annular groove. A circle of ring-shaped protrusion is arranged at the tail end of an inserting port pipeline. One side of the tail end, close to the inserting port, of the protrusion part is provided with the gradient with the tilt angle ranging from 15 degrees to 45 degrees, and pipeline inserting port installation is convenient. The metal limiting ring is composed of three sets of arcs of 120 degrees, the cross section is in an L shape, and the part, protruding close to the outer side, of the metal limiting ring is used for installing and fixing the metal ring to the position of the groove of a bell mouth pipeline. After a single pipeline connector is pulled and deformed to the extreme, each pipeline can drive an adjacent pipeline to slide together, pipeline deformation is transmitted to an adjacent pipeline connector, and the capability of resisting large deformation of a soil body around the pipeline is achieved finally.

Description

technical field [0001] The invention relates to an anti-seismic joint for connecting ductile cast iron pipelines, which is an anti-seismic pipeline joint capable of resisting large deformation, and belongs to the technical field of urban water supply pipeline applications. Background technique [0002] As an important part of urban lifeline project, water supply system is an important link to ensure the normal operation of urban functions and an important guarantee for urban development and national economy. Buried water pipelines have the characteristics of wide distribution and long transportation distances. Therefore, it is inevitable to pass through complex geological conditions, such as faults, landslides, and subsidence areas. Buried pipelines are sensitive to changes in site conditions, especially when earthquakes occur, which will cause relative displacement between the pipe and soil, which is likely to cause large deformation or even damage to the pipeline, threaten...
