Problems solved by technology

[0004] The purpose of the patent of the present invention is to provide a method to achieve a tight seal on the connecting pipe, which can not only eliminate or reduce the impact pressure of the pipe's water hammer through the outward displacement of the pipe in the pipe fitting, but also increase the volume of the pipe. The telescopic displacement of the pipe in the pipe fittings is used to compensate the change in the length of the pipe caused by thermal

Embodiment Construction

[0011] 1. Installation of plug-in telescopic compensation pipe fittings

[0012] Put the thrust rubber ring 2, steel ball ring 3, and positioning rubber ring 4 on the conical inner groove 6 of the insert 1 in sequence. Since the inner diameter of the positioning rubber ring 4 is smaller than the bottom diameter of the conical inner groove 6, Therefore, the elastic contraction force of the apron presses the steel ball ring 3 against the thrust apron 2 under the action of the slope of the conical inner groove 6, so that the steel ball ring 3 is sandwiched by the thrust apron 2 and the positioning apron 4 holding. The outer diameters of the thrust rubber ring 2, the steel ball ring 3 and the positioning rubber ring 4 placed on the conical inner groove 6 are respectively larger, slightly smaller and smaller than the inner diameter of the connecting pipe 8, and the inner diameter of the sealing rubber ring 5 is smaller than that of the circular ring The bottom diameter of inner gr...

Abstract

The invention discloses an expansion compensation connecting pipe fitting. The expansion compensation connecting pipe fitting has the characteristics that a connecting pipe can be subjected to tight coupling by the pipe fitting; expansion displacement can be achieved in the pipe fitting by the connecting pipe; a combined stress formed by a pipeline connected with the pipe fitting in any severe working condition environment is less than an allowable stress of a pipe material all the time; and the problem that the use safety and the reliability of the existing pipeline are poor is effectively solved.

Description

technical field [0001] The patent of the invention relates to a pipe connecting pipe fitting, which is especially suitable for pipelines with harsh working conditions. Background technique [0002] Pipeline transportation is the simplest transportation mode for medium transportation. Pipes must be connected by pipe fittings to become pipes. The reliability of pipe connection determines the safety and reliability of pipeline use. Therefore, it is necessary to develop pipe fittings with better connection performance to improve pipeline quality. [0003] At present, the stress of the pipe wall of the building water supply pipe is calculated according to the working pressure, and the safety factor of the pipe wall strength is very high. The damage of the pipeline, so the pipeline should be equipped with telescopic compensation pipe fittings to reduce the incidence of pipeline accidents. However, due to the relatively expensive telescopic compensation pipe fittings used at prese...
