Description
Technical field
The utility model is related to pipe technology field, specifically a kind of HDPE both arms bellows.
Background technology
HDPE double-wall corrugated pipes are, using polyvinyl resin as primary raw material, to add appropriate amount of addition agent, extruded shaping, application
More and more extensively, building, communication, agricultural are gradually applied to.With lightweight, resistance is small, compression strength is high, easy construction
The advantages of, it is the ideal material for replacing cast iron pipe and Cement Concrete pipe.Existing HDPE double-wall corrugated pipes bulk strength is poor, by crowded
Pressure-volume is easily worn and torn after being also easy to produce rupture, and the permanent use of high spot by the external world, greatly reduces service life.
HDPE double-wall corrugated pipes are usually the outer wall layer of smooth inner wall layer and outline undulate, this kind of due to reasons in structure
The ring stiffness of HDPE double-wall corrugated pipes is relatively low, and critical external compressive resistance load capacity is relatively poor, and tubing easily deforms.
Therefore, to overcome the shortcomings of that above-mentioned technology is designed a simple in construction, wearability is good, critical external compressive resistance load capacity
By force, ring stiffness is high, and pipeline is not easily broken, and can extend a kind of HDPE both arms bellows of pipeline service life, exactly inventor institute
The problem of solving.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of HDPE both arms bellows, the letter of its structure
Single, wearability is good, and critical external compressive resistance load capacity is strong, and ring stiffness is high, and pipeline is not easily broken, and can extend pipeline service life.
The utility model solves the technical scheme that its technical problem used：A kind of HDPE both arms bellows, it includes
There are inner tube, outer layer bellows, the internal layer pipe outer wall is connected with outer layer bellows, between the inner tube and outer layer bellows
Include two in hollow space and tilt one fan of formation between symmetrically arranged reinforcement, reinforcement and the outer layer bellows
Rubber layer is filled between shape face, the sector, the outer surface of the outer layer bellows is provided with wearing layer.
Further, the height of the reinforcement is 1/2nd of outer layer bellows waveform crest height.
Further, the internal layer inside pipe wall is provided with corrosion-resistant finishes.
The beneficial effects of the utility model are：
1st, the utility model is simple in construction, available for bigbore pipeline is made, between inner tube and outer layer bellows
The reinforcement that hollow space is set can strengthen the bearing capacity of pipeline, improve corrugated pipe ring rigidity, and reinforcement is inclined symmetrical
It is arranged in hollow space, stressed effect is good, intensity is high.The sector formed between the connected outer layer bellows of reinforcement
The rubber layer of interior setting is flexible, and the pressure being subject to outside energy absorption tube and in inner tube, pipeline entire compression ability is strong, pipeline
It is not easily broken, increases the service life.One layer of wearing layer is coated in the outer wall of outer layer bellows, strengthens pipeline anti-wear performance, is suitable to
Used in bad environments situation.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals：1- inner tubes；2- anti-corrosion layers；3- rubber layers；4- reinforcements；5- outer layer bellowss；6- is resistance to
Grind layer.
Embodiment
With reference to specific embodiment, the utility model is expanded on further, it should be appreciated that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values also fall within application
Appended claims limited range.
The utility model structural representation referring to Fig. 1, a kind of HDPE both arms bellows of the structure, include inner tube 1,
Outer layer bellows 5, the outer wall of inner tube 1 is connected with outer layer bellows 5, is wrapped between inner tube 1 and outer layer bellows 5 in hollow space
Two are included and have tilted symmetrically arranged reinforcement 4, the section between reinforcement 4 and outer layer bellows 5 forms a sector, fan
Rubber layer 6 is filled between shape face, the outer surface of outer layer bellows 5 is provided with wearing layer 6, and the height of reinforcement 4 is outer layer ripple
/ 2nd of the waveform crest height of line pipe 5, the inwall of inner tube 1 is provided with anti-corrosion layer 2.
The utility model is simple in construction, is made of being integrally formed, convenient for production, and pipeline various pieces connectivity is good,
It can be used for bigbore pipeline is made simultaneously.The reinforcement that hollow space between inner tube and outer layer bellows is set can strengthen
The bearing capacity of pipeline, improves corrugated pipe ring rigidity, and reinforcement is inclined is symmetricly set in hollow space, stressed effect
Good, intensity is high.The corrosion-resistant finishes that inwall is set can strengthen the corrosion resistance of inside pipe wall, strengthen pipeline transport capacity.Reinforcement
The rubber layer set in the sector that is formed between connected outer layer bellows is flexible, can absorption tube is outer and inner tube
The pressure being inside subject to, pipeline entire compression ability is strong, and pipeline is not easily broken, and is increased the service life.In the outer wall of outer layer bellows
One layer of wearing layer is coated, strengthens pipeline anti-wear performance, suitable for being used in bad environments situation.
