Problems solved by technology

[0003] At present, in the connection of underground pipelines, its flexible structure is often used with sealing rings. Although it is guaranteed to adapt to the displacement and deformation caused by temperature changes, when a major earthquake occurs, the deformation of the pipeline nodes will not meet the displacement required for earthquake resistance. Pipeline nodes deform and fall off under huge tension, causing damage

Embodiment Construction

[0041] The present invention is described in detail below in conjunction with the accompanying drawings: the anti-seismic threaded pipe connector includes a connector socket (1), a connector socket (2), a water-stop rubber ring (3), a socket flange (4) and a socket method Orchid plate (5).

[0042] Install the water-stop rubber ring (3) at the position of the annular protrusion (1a) of the connector socket (1) first;

[0043] After installing the water-stop rubber ring (3), insert the connector socket (2) into the socket (1). Before inserting, apply a layer of lubricant to the water-stop rubber ring to facilitate installation.

[0044]After installing the water-stop rubber ring (3) to the position of the annular protrusion (1a) of the socket, insert it into the pipe socket (2), when the external thread (2b) of the socket contacts the internal thread (1b) of the socket, start screw in. After the screw-in is completed, continue to insert until the ring groove (2a) of the socke...

Abstract

The invention discloses an anti-seismic threaded pipeline connecting part. The anti-seismic threaded pipeline connecting part comprises a connecting part socket, a connecting part inserting opening, awater-stop rubber ring, a socket flange plate and an inserting opening flange plate. An annular protrusion and an inner screw thread are disposed in the connecting part socket; a circle of annular groove and an outer screw thread are formed in an inserting opening pipeline, and in order to conveniently perform mounting, 15 degree-45 degree slope treatment is performed on all portions of the connecting part. In the mounting process of the connecting part inserting opening, the water-strop rubber ring is squeezed and deform to be fixed at the inserting opening annular groove, and therefore theeffects of sealing and water stopping are enhanced. When the pulling force exerted on a pipeline is small, the anti-pulling force is provided by the frictional force between the connecting part inserting opening and the water-stop rubber ring; and when the pulling force is larger than the frictional force, the inserting opening annular groove is pulled by a certain distance, then the inner screw thread of the connecting part socket makes contact with and is engaged with the outer screw thread of the inserting opening, the connecting part is prevented from continuing to be pulled and separated,and therefore the function of restraining excessive deformation and failure of the pipeline is achieved.

Description

technical field [0001] The invention relates to an anti-seismic threaded connecting piece for connecting pipelines, which is a pipeline connecting piece capable of resisting large deformation. Background technique [0002] Underground pipelines play a vital role in lifeline engineering. They are buried underground for the transportation of various media such as water. Since buried pipelines usually perform their functions in the form of a network system and are distributed over a wide area, it is inevitable that they will pass through sites with different geological conditions, including areas with active seismic activity. In these underground pipelines, the pipeline node is an important connection point, and at the same time it is a very weak point, which is highly sensitive to changes in site conditions. According to the investigation and research of earthquake disasters around the world in recent years, buried pipelines will suffer damage such as disconnection and fractu...
