Description
[ technical field ] A method for producing a semiconductor device
The utility model belongs to the technical field of the technique of winding union coupling and specifically relates to an anti formula socket joint connection structure that subsides for drain pipe.
[ background of the invention ]
Along with the urbanization construction in China, the demand of municipal drainage pipelines is multiplied every year, and HDPE hollow-wall winding pipes have the advantages of high rigidity, good toughness, long service life, light weight, recoverability and the like, so that the HDPE hollow-wall winding pipes are widely applied to municipal engineering all over the country once being introduced.
The HDPE hollow wall winding pipe has three main connection modes, one is connection of a PE heat shrinkage sleeve, the bonding strength of the PE heat shrinkage sleeve depends on the thickness of the heat shrinkage sleeve, a gap is easily formed due to uneven heating during bonding, leakage points are generated, the requirement on the construction environment is high, and the construction difficulty is high. The second is electric hot melting belt connection, which has high requirements on construction environment, and the construction is live working, thus increasing the construction danger. The third is socket connection, which is a convenient, fast, safe and efficient connection mode in pipeline installation. However, in the existing socket connection mode, when the pipeline is settled, the joint is easy to disconnect, so that the pipeline is easy to leak.
[ Utility model ] content
The utility model aims at solving the problem in the prior art and providing an anti-settling pipe injection joint with good sealing reliability.
In order to realize the above purpose, the utility model provides an anti tubular product injection joint that subsides, including welding bellmouth and the main bellmouth that integrated into one piece connects in proper order, main bellmouth comprises the anti section of subsiding and rubber ring socket joint section that connects gradually, the internal diameter of rubber ring socket joint section is greater than the internal diameter of anti section of subsiding.
Preferably, the front end of the main bell mouth is provided with an annular retainer ring connected with the welding bell mouth.
Preferably, the anti-settling section and the rubber ring socket connecting section are in transition connection through a conical section.
Preferably, the inner diameter of the anti-settling section is 5-15 mm larger than the outer diameter of the corresponding pipe, and the length of the anti-settling section is 60-120 mm.
Preferably, the inner diameter of the anti-settling section is 2-3 mm larger than the outer diameter of the front part of the rubber ring matched with the pipe.
Preferably, the length of the anti-settling section accounts for 1/3-1/2 of the total length of the main bellmouth.
Preferably, the inner diameter of the rubber ring socket joint connecting section is 5-10 mm larger than that of the anti-settling section.
The utility model has the advantages that: 1. the inner diameter of the anti-settling section is 2-3 mm larger than the outer diameter of the front part of the rubber ring matched with the pipe, so that when the pipe is settled, the anti-settling section can well support the weight of the pipe, not only can the good matching of the pipe be ensured, but also a small effective gap can be ensured, a good supporting effect can be achieved, the phenomenon that the sealing effect is damaged due to the fact that the gap at one side is too large because the whole weight is borne by the rubber ring is avoided, and the phenomenon that the rubber ring is separated from the pipe and the sealing is damaged due to the fact that the angle deviation between the bearing ends and the;
2. the inner diameter of the rubber ring socket joint connecting section is 5-10 mm larger than the inner diameter of the anti-settling section, the gap of the rubber ring socket joint connecting section is slightly larger than the inner diameter of the anti-settling section, the rubber ring is used for sealing, the height design of the rear peak of the rubber ring can be guaranteed to reach effective compensation amount, the rubber ring is deviated and the leakage condition occurs when the pipeline is prevented from settling, the sealing performance of the pipeline during settling is guaranteed, and even if the outer diameter of a bell mouth and the outer diameter of a pipe are changed to a certain extent, the good.
3. The anti-settling section and the rubber ring socket connecting section are in transition connection through the conical section, so that the overall rigidity of the main bell mouth is enhanced, and the deformation resistance is improved; meanwhile, the pipe is not blocked and smoothly put in place during installation.
The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
