Abstract
The utility model discloses a kind of interface strengthening formula PVC-M double-wall corrugated pipe, a kind of double-wall corrugated pipe, include smooth inwall and in shape of threads spiral and under outer wall, described double-wall corrugated tube faucet side is provided with inside in-flanges, described double-wall corrugated pipe socket side is provided with outside flanging, and described bellmouth in-flanges and the lucky engagement sleeves of socket flanging are plugged together.By force, good toughness, enhances entire compression intensity for spiraling in shape of threads of the utility model design and lower new waveform outer wall construction rigidity; Two being threaded of corrugated tube port uniqueness makes threaded pipe bellmouth and is connected convenient between socket and firmly, extends the working life of double-wall corrugated pipe.
Description
Technical field
The utility model relates generally to a kind of both arms bellows, particularly relates to a kind of interface strengthening formula PVC-M double-wall corrugated pipe.
Background technique
Double-wall corrugated pipe is not only applied in buried draining, drainage pipeline aspect, in other different fields, application is also more and more extensive, as cable protection double-wall corrugated pipe, field irrigation or water drainage double-wall corrugated pipe, the double-wall corrugated pipe of old urban area gaspipe network transformation and subway ventilation, mine ventilation double-wall corrugated pipe etc., but present double-wall corrugated pipe structural rigidity is poor, poor toughness, transport, link cost is high, connect difficulty large, poor air-tightness, therefore a kind of structural rigidity how is designed strong, toughness is good, easy to connect and firmly double-wall corrugated pipe be the problem that related domain need solve.
Model utility content
The utility model object is exactly the defect in order to make up prior art, provides a kind of interface to strengthen formula PVC-M double-wall corrugated pipe.
The utility model is achieved through the following technical solutions:
A kind of double-wall corrugated pipe, include smooth inwall and in shape of threads spiral and under outer wall, described double-wall corrugated tube faucet side is provided with inside in-flanges, described double-wall corrugated pipe socket side is provided with outside flanging, described bellmouth in-flanges and the lucky engagement sleeves of socket flanging are plugged together, described bellmouth in-flanges relative bellmouth tube wall side is provided with internal thread one, and socket flanging is provided with the outside thread one of supporting internal thread one relative to socket tube wall side; Be provided with outside thread two outside described socket flanging, inside bellmouth, tube wall corresponding position is provided with the internal thread two of supporting outside thread two.
The oval cross section that the circle screw thread that described double-wall corrugated pipe outer wall intercepts along any point is formed and double-wall corrugated pipe place straight line are 45 degree of angles.
The utility model has the advantages that:
By force, good toughness, enhances entire compression intensity for spiraling in shape of threads of the utility model design and lower new waveform outer wall construction rigidity; Two being threaded of corrugated tube port uniqueness makes threaded pipe bellmouth and is connected convenient between socket and firmly, extends the working life of double-wall corrugated pipe.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of double-wall corrugated pipe, include smooth inwall 1 and in shape of threads spiral and under outer wall 2, described double-wall corrugated tube faucet 3 side is provided with inside in-flanges 4, described double-wall corrugated pipe socket 5 side is provided with outside flanging 6, described bellmouth in-flanges 4 and socket flanging 6 just engagement sleeves are plugged together, the described relative bellmouth 3 tube wall side of bellmouth 3 in-flanges 4 is provided with internal thread 1, and the relative socket 5 tube wall side of socket 5 flanging 6 is provided with the outside thread 1 of supporting internal thread 1; Be provided with outside thread 29 outside described socket 5 flanging 6, inside bellmouth 3, tube wall corresponding position is provided with the internal thread 2 10 of supporting outside thread 29.
The oval cross section that the circle screw thread that described double-wall corrugated pipe outer wall 2 intercepts along any point is formed and double-wall corrugated pipe place straight line are 45 degree of angles.
