Description
Technical field
The utility model relates to pipe technology field, is specially a kind of metallic hose and is wound around enhancing carat pipe.
Background technique
Now, being wound around enhancing carat pipe is the buried rain, the dirty waste pipe that have all generally used both at home and abroad already, has the advantages such as service life is long, steady quality is reliable, electro-fusion socket is easy to connect, good leak tightness.
The increase of urban population number, in the designing requirement medium caliber of buried pipeline in continuous increasing, simultaneously along with the increasing of bore, also need the larger buried degree of depth, the ring stiffness index that these conditions all require tubing to possess more to increase, prevents from occurring the phenomenons such as conquassation in using process.
But present winding strengthens carat pipe majority and adopts polyethylene wound pipe, and cost is very high, and ring stiffness is lower, often occurs the phenomenon that entwining tube ruptures have impact on the up-to-standard rate of product in course of conveying.
Summary of the invention
The technical problem that the utility model solves is that providing a kind of metallic hose to be wound around strengthens carat pipe, to solve the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of metallic hose is wound around and strengthens carat pipe; comprise body; the outer surface spiral winding of described body has reinforced pipe; described reinforced pipe is made up of two-layer; internal layer is metallic hose; skin is polyethylene pipe; the outer wall welding of described polyethylene pipe and described body; described metallic hose is attached on the inwall of described polyethylene pipe; described metallic hose is metal bellows; and the wall thickness of described metallic hose is 1/3-1/5 of described polyethylene pipe wall thickness, the diameter of described metallic hose is 1/10-1/20 of described pipe diameter;
The outer surface of described body is gone back the stiffening rib that spiral winding has semicircular arc-shaped, described stiffening rib is between the described reinforced pipe of adjacent turn, and the diameter of described stiffening rib is 1/6-1/8 of described reinforced pipe diameter.
In the utility model, the wall thickness of described metallic hose is 1/4 of described polyethylene pipe wall thickness.
In the utility model, the diameter of described metallic hose is 1/15 of described pipe diameter.
In the utility model, the section tubular wall of described polyethylene pipe bottom and described body welding one, and the length of this section tubular wall is 1/6 of described polyethylene pipe cross-sectional periphery length.
Owing to have employed above technological scheme, the utility model has following beneficial effect:
Reduce costs, metallic hose existing cost ratio polyethylene raw material are low by 2/3, and greatly reducing winding structure pipe formula for raw stock cost, is be wound around the development trend strengthening structured wall popes in the future.
Enhance product performance: while reducing costs, product performance (ring stiffness) are improved.Table 1
| Title | Specification | Ring stiffness (KN) | Weight (KG) |
| Carat pipe | 500 | 6.5 | 95 |
| Reinforced by Metal carat pipe | 500 | 8.2 | 95 |
Through detecting, under the weight of equivalents, product performance obtain providing more than 15%.Metal strength is greater than 450MPA, plastic strength 25MPA.
Product ring stiffness is high, can be wound around bilayer or multilayer.Can according to customer requirement, the highest 16KN-20KN that produces is a kind of novel product that current domestic drainage pipe product performance are the highest.
Production technology is simple, reduces when conveying produced by original PP pipe and has phenomenon of rupture, improve conforming product rate, reduce costs.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, a kind of metallic hose is wound around and strengthens carat pipe, comprise in body 1(Fig. 1 the sidewall sections that body 1 is only shown), the outer surface spiral winding of described body 1 has reinforced pipe 2, described reinforced pipe 2 is made up of two-layer, internal layer is metallic hose 3, skin is polyethylene pipe 4, the outer wall welding one of described polyethylene pipe 4 and described body 1, described metallic hose 3 is attached on the inwall of described polyethylene pipe 4, described metallic hose 3 is metal bellows, and the wall thickness of described metallic hose 3 is 1/3-1/5 of described polyethylene tube wall 4 thickness, the diameter of described metallic hose 3 is 1/10-1/20 of described body 1 diameter, the outer surface of described body 1 is gone back the stiffening rib 5 that spiral winding has semicircular arc-shaped, described stiffening rib 5 is between the described reinforced pipe 2 of adjacent turn, and the diameter of described stiffening rib 5 is 1/6-1/8 of described reinforced pipe 2 diameter.
Inventor finds in long-term practice, the wall thickness of metallic hose 3 and the impact of the diameter of metallic hose 3 on whole carat pipe very large, if wall thickness and diameter are greater than the maximum ratio that the utility model provides, intensity increases to bottleneck, can not continue to increase too much, but cost can improve too large, if wall thickness and diameter are less than the minimum scale that the utility model provides, intensity can significantly decline.Therefore, inventor selects the wall thickness of the metallic hose 3 adopted to be 1/4 of described polyethylene tube wall 4 thickness, and the diameter of described metallic hose 3 is 1/15 of described body 1 diameter.
In the utility model, the section tubular wall of described polyethylene pipe 4 bottom and described body 1 welding one, inventor find when the length of this section tubular wall (as Fig. 1 dotted line illustrates) be as described in polyethylene pipe 4 cross-sectional periphery long 1/6, intensity is the highest.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
