Groove pipe joint preassembling snap ring piece

Abstract

A groove pipe joint preassembling snap ring piece comprises a groove pipe joint preassembling snap ring, the groove pipe joint preassembling snap ring is a complete annular ring body formed by two semi-circular rings, a protruding part is arranged in the middle of the inner wall of the groove pipe joint preassembling snap ring, and the protruding part is matched with an annular groove in the position of a groove pipe joint for fixing a groove connecting steel pipe. And the inner walls of the groove pipe joint preassembled clamping rings at the two ends of the convex part are in contact with the outer-diameter cylindrical surface of the groove pipe joint of the fixed groove connecting steel pipe. After being connected with a fixed groove connecting steel pipe, the groove pipe preassembling connector can bear pressure and bending force from the interior of a pipeline through the groove pipe connector preassembling clamping ring and can also bear thrust, and connection of the pipeline groove connecting steel pipe is facilitated. The contact area between the groove pipe joint preassembling snap ring and the groove connecting steel pipe of the pipeline is large, so that the groove pipe preassembling joint is stably connected with the groove connecting steel pipe of the pipeline, is not easy to fall off, and is high in safety.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection of steel pipelines in the field, and particularly relates to a grooved pipe joint pre-installed clamp in a grooved pipe joint pipeline. Background technique [0002] In modern warfare, the main way to guarantee oil in wartime is to rely on oil pipeline transportation. It is a basic work that must be done in preparation for military struggle to ensure that oil pipelines reach the designated position in time and accurately so as to ensure the smooth flow of oil in wartime. Connect multiple steel pipes together to form an oil pipeline. Prefabricated joints for grooved steel pipes are mainly used in the connection between grooved steel pipes in pipelines and fixed equipment such as booster pump stations and relatively fixed grooved connection pipes such as connecting valves. After the grooved steel pipe of the pipeline is changed to the socket connection form, the joint form of the groove...

AI Technical Summary

Problems solved by technology

When the pre-installed connector body and the fixed grooved steel pipe 3' are used in a bending state and in a high-pressure environment, leakage will occur at the pre-installed joint of the grooved pipe, and in severe cases, the grooved connection steel pipe between the pre-installed joint of the grooved pipe and the pipeline will occur falling off, causing a safety accident
