Description

Quick disassembly and assembly connecting structure and connecting method for fire fighting pipeline

The technical field is as follows:

the invention relates to the technical field of fire fighting pipeline installation, in particular to a quick disassembly and assembly connecting structure and a quick disassembly and assembly connecting method for a fire fighting pipeline.

Background art:

two pipelines are often required to be connected in series in the fields of fire-fighting pipeline construction, water heating pipeline construction and the like. In the prior art, a malleable iron galvanized pipe joint is mainly adopted to connect two pipelines, the pipelines are in threaded connection with the pipe joint, and a sealing strip is wound at the threaded connection position for sealing. Although the pipeline can be connected in series in the prior art, some outstanding problems still exist: firstly, the external thread of the pipeline needs to be processed on site, which undoubtedly increases the difficulty and the construction period of site construction; secondly, the maintenance is difficult, when the middle pipeline needs to be disassembled for maintenance, the pipeline connected in series behind the middle pipeline needs to be disassembled for taking down, although the operation difficulty is not great, the operation is very complicated, and time and labor are wasted.

In order to simplify the installation operation, improve pipeline construction efficiency, make the pipe connection design more reasonable, and tend to perfect, prior art has carried out various attempts, try to make device overall structure more reasonable, nevertheless there are some not fully satisfactory parts always, for example chinese patent ZL2014200921844 discloses a fire control pipe footpath pipeline quick connector, this technical scheme has realized that the pipeline is connected with the alignment (parallel and level) of coupling, need not to process the screw thread on the pipeline, it is more convenient to install, later stage maintenance dismantlement is convenient. However, the technical scheme also has some limitations, namely, the diameter of the pipe fitting is larger than that of the steel pipe, and the diameter of the connecting piece is larger than that of the pipe fitting, so that the overall structural design is overlarge and heavy, the installation efficiency is influenced, and the operation in a narrow installation space is very unfavorable; secondly, during installation, the connecting piece is sleeved on the steel pipe, then the clamping ring is installed in the clamping groove of the steel pipe, and finally the connecting piece is connected with the pipe fitting in a threaded manner, three steps are needed to be completed, and the installation operation needs to be further simplified; thirdly, the snap ring and/or the clamping groove are easy to separate from the clamping groove due to long-time wear or corrosion and the like, so that the pipeline connection is failed, and the reliability of the pipeline connection structure needs to be improved; fourthly, the sealing effect is poor, side leakage is easy to occur, and the main reasons for the poor sealing effect are two points: firstly, a larger distance exists between the connecting piece and the steel pipe, and the steel pipe is difficult to ensure that the steel pipe and the center of the pipe fitting are aligned and installed due to the fact that the steel pipe is longer in actual installation, so that the radial direction of the steel pipe is easy to deviate; and secondly, the end parts of the pipe fitting and the steel pipe for extruding the sealing gasket are end planes, and the steel pipe and the pipe fitting are difficult to align in actual installation, so that one surface of the sealing gasket is stressed slightly, the other surface of the sealing gasket is stressed slightly, and finally the sealing gasket is not tight to cause the problem of side leakage, and meanwhile, the sealing gasket is easy to damage locally due to uneven stress.
