Description
Technical field
The present invention relates to a kind of bellows more particularly to a kind of outer muscle enhancing bellowss of internal-rib.
Background technology
Bellows has the housing of the cylinder-shaped thin wall wrinkle of multiple transverse waves.Bellows is generally by PP, PA or PE material
Material is made, and has elasticity, displacement or bending can be generated under pressure, axial force, cross force or Moment.It had been bent
Cheng Zhong due to the housing that bellows is the cylinder-shaped thin wall wrinkle with multiple transverse waves, can be bent to any direction.By
In the non-directional flexural property of bellows, it is made to be widely used in the line of Building wood and mechanical equipment.In addition, in
Bellows is also used as hollow reinforced rib in the production of the outer ripple plastic winding structure wall pipe of empty reinforcing rib, it is main former
It because can be arbitrarily to the characteristic of bending using bellows.
It is that the fluids such as various liquid or gas carry out the important of conveying connection since bellows has the characteristic of arbitrary bending
One of pipeline is widely used in the various occasions such as dish cleaning machine, air conditioner, bathhouse, water heater, Medical Devices
Water supply, draining, blowdown, exhaust, ventilation etc., in application bellows, it is desirable that bellows has good intensity, and installation side
Just.
Wherein, in the construction of municipal blow-off line, for reduction effluent seepage, protect underground water source and soil not contaminated,
Large-bore plastics drainpipe is promoted the use of in large quantities.It is small that buried gravity flow drainage pipeline generally bears internal pressure, need to mainly improve anti-
Soil epipolar restriction.This just needs the ring stiffness on the one hand improving tubing, on the other hand by increasing the combination of tubing and soil
Area strengthens the compactness of backfill to improve pipeclay collective effect, to improve tubing crushing resistance.Steel band currently on the market increases
Strength polyethylene (PE) helical bellows, polyethylene plastic steel wound drain pipe, Double-flat wall steel plastic drainpipe, hard polyvinyl chloride (PVC-
U) steel plastic composite wound pipe etc. is all the ring stiffness for enhancing tubing by way of composite steel band.But the technology of steel plastic compount also has
To be improved, the problems such as the poor corrosion resistance of steel, making steel modeling class multiple tube, there are still one when for conveying corrosive sewage
Fixed security-hidden trouble.
Heavy caliber pure plastic pipe mainly has polyethylene or corrugated dual-wall hard PVC pipe, hard polyvinyl chloride reinforcement at present
Pipe, reinforced polypropylene (FRPP) molding pipe, polyethylene winding structure wall pipe A types, polyethylene winding structure wall pipe Type B.Respectively
The axial part section structure of kind tube material and tube wall is respectively as shown in a, b, c, d and e of Fig. 1.
Currently for this problem, Chinese patent CN101907211A discloses a kind of outer ripple plastic of internal-rib enhancing and twines
Around structure-wall pipe material and its manufacturing method, as shown in Fig. 2, including spiral shell cylindrical surface tubing ontology and spiral surrounding on the outside of tube body
Rotation is surround, and spiral surrounding includes an enhancing internal-rib perpendicular to tube wall, the internal-rib by spiral surrounding be divided into two it is arranged side by side
Hollow cavity.It the advantage is that：The solid projection at the top of outer ripple and its wave crest that its structure type has, improves tubing appearance
Area, using when the pipeclay collective effect that is formed be superior to polyethylene winding structure wall pipe A type pipes and (be commonly called as hollow wall
Pipe).Since its structural walls height is big so that pipeclay collective effect also run well by more common double-wall corrugated pipe and winding ripple.
Internal-rib disclosed in heavy caliber pure plastic pipe and Chinese patent from the above-mentioned prior art, which enhances outer ripple plastic, to be twined
Around structure-wall pipe material it can be seen that, currently for the pure plastic film capicitor of heavy caliber main improved though always all around pipe
It is designed in the shape of spiral surrounding on body, volume, it is preferable to obtain by changing the volume and shape of spiral surrounding
Ring stiffness, and then heavy caliber pure plastic pipe is made to be hardly damaged in construction and installation, using effect is more preferable, longer life expectancy.
But in actual use, the use environment of heavy caliber pure plastic pipe often becomes increasingly complex, for example, by using buried
The heavy-caliber plastic pipe of formula installation not only needs the pipe outer surface product for improving its own to improve pipeclay style of work effect, also needs
Improve the situation of resistance to compression, antidetonation and artificial destruction.
It can be seen that the shape to its spiral surrounding, body are confined to the improvement of bellows in currently available technology
Improvement in product causes the limitation of industry development, makes bellows in the performances such as resistance to compression, anti-deformation and pipeclay effect
Raising is restricted.
