Embodiment Construction

[0065] Figure 1-7 Among them, the safety joint for grooved steel pipe consists of a connector body 1, a grooved pipe joint snap ring 3, a steel locking ring 2, and a sealing rubber ring 4. Connector body 1. Grooved pipe joint snap ring should be made of 35Cr or thick-walled pipe with the same strength. Steel locking rings shall be manufactured using 65Mn cold drawn spring steel wire. The sealing rubber ring 4 should be made of nitrile oil-resistant rubber or synthetic oil-resistant rubber. The hardness of the outer surface of the connector body 1 is not lower than HRC28, and the surface hardness of the inner R3 arc is not lower than HRC32. The surface hardness of the grooved pipe joint snap ring 3 is not lower than HRC28, and the surface hardness of the steel locking ring 2 is not lower than HRC32. The steel locking ring 2 is in the shape of a circular ring with notches, and its inner diameter is slightly smaller than the outer diameter of the grooved pipe joint at the end...

Abstract

A safety joint for a grooved steel pipe comprises a connector body, a sealing rubber ring, a steel locking ring and a grooved pipe joint clamping ring, the sealing rubber ring is arranged in an inner-end straight groove and an outer-end straight groove, and the steel locking ring is arranged at a notch of the outer-end straight groove to form a connector body combined body; the groove pipe joint snap ring is arranged at the annular groove of the groove pipe joint of the pipeline groove connecting steel pipe to form a groove connecting steel pipe assembly; when the steel locking ring is arranged between the inner arc-shaped groove and the outer arc-shaped groove in the bellmouth connecting process of the groove connecting steel pipe combination body and the connector body combination body, the steel locking ring, the inner arc-shaped groove and the outer arc-shaped groove form a cambered surface fine adjustment mechanism. Flexible connection with the two-end connecting groove connecting steel pipe combination body of the connector body combination body is achieved through the cambered surface fine adjustment mechanism, the connector body combination body can generate a relative bevel state relative to the two-end connecting groove connecting steel pipe combination body, and the device can be more suitable for various complex occasions used in the field.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection of field steel pipelines, and in particular relates to a socket connector for flexible connection between steel pipes connected by pipeline grooves. Background technique [0002] In modern warfare, the main way of oil supply in wartime is to rely on oil pipelines. It is a basic work that must be done well in the preparation of military struggles to ensure that the oil pipelines arrive at the designated location in time and accurately so as to ensure the smooth flow of oil in wartime. For a large number of pipelines that are frequently connected and disassembled to replace the delivery site, frequent connection and disassembly operations are performed between the pipeline and the connector. The distance of oil pipelines is getting longer and longer, so more and more connectors are needed to connect them, and the frequency of maintenance and replacement is increasing. With the complexit...
