Abstract
The invention relates to a steam flow plastic corrugated pipe, which belongs to the technical field of fluid conveying pipelines. A hose comprises a body which is formed by spirally winding a base strip with a corrugated section; spiral supporting ribs are lined in the body; the corrugated shape has three wave crests and two wave troughs; the outer surface of the third wave crest in the previous circle of three wave crests of two adjacent circles of the wound base strip is hermetically attached to the inner surface of the first wave crest in a next circle of three wave crests, and the inner surface of the third wave crest of the previous circle is matched and attached with the outer contours of the sections of the spiral supporting ribs; and a silica gel pipe penetrates through envelope inner holes of the spiral sporting ribs. The plastic body is effectively prevented from being softened and ruptured due to over high temperature, and meanwhile has a heat insulation effect, the heat dissipation of the body is obstructed, and the loss in a heat energy transfer process is obviously reduced. The steam flow plastic corrugated pipe has good strength and ideal bending flexibility, and softening rupture and aging fracture can be avoided.
Description
Technical field
The present invention relates to a kind of bellows, especially a kind of logical steam plastic film capicitor belongs to the fluid delivery pipeline technical field.
Background technique
Understand according to the claimant, the body of existing plastic flexible pipe is corrugated PVC base bar self coiled coil by the cross section and consists of, and its typical structure can be 200910173470.7 Chinese patent application document referring to application.
When this bellows during for delivery of steam, is wherein passed the silicone tube of logical steam.Because the convex place between the pvc pipe body two adjacent rings spiral grooves can directly contact with silicone tube, therefore be easy to break because excess Temperature softens, not breaking even soften in bending part when especially using, can be because of the aging bending phenomenon of rupture that occur yet.
In addition, the pvc pipe body has also caused easy heat radiation with direct contact of silicone tube, is unfavorable for heat preservation energy-saving.
Summary of the invention
The object of the invention is to: for the shortcoming that above-mentioned prior art exists, propose a kind of logical steam plastic film capicitor that breaks and bend fracture of can effectively avoiding softening.
In order to reach above purpose, logical steam plastic film capicitor of the present invention comprises by the cross section and is the body that corrugated basic bar self coiled coil consists of, and is lined with the spiral support muscle in the described body; Described corrugated have three crests and two troughs; The internal surface sealing of the primary peak in the 3rd crest outer surface in three crests of the last circle of the basic bar two adjacent rings of described coiling and three crests of a rear circle is fitted, and the applying that matches of the cross section gabarit of the internal surface of described last circle the 3rd crest and described spiral support muscle; Pass silicone tube in the envelope endoporus of described spiral support muscle.
As a result, form double-head inner thread in the body, the cylindrical of spiral support muscle is supported in one of double-head inner thread.The present invention compares with existing technology, and during the flexible pipe bending, body is outwards heaved, and forms compressible nargin, and therefore easily bending can not produce fracture phenomena because of tension.When steam tube inside was inserted with the silicone tube that logical steam uses, silicone tube did not directly contact with body, can play heat-blocking action, and the screw thread supporting rib contacts with the silicone tube interval to convex simultaneously, has further brought into play effect of heat insulation.
It is that described spiral support muscle is made of metal-cored outsourcing plastic surface layer that the present invention further improves.Like this can be when flexible bending, avoid silicone tube and Metal Phase mutual friction and damage, effectively protect silicone tube, have simultaneously further heat-blocking action.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is Fig. 1 embodiment's A-A sectional view.
Fig. 3 is the B place broken section enlarged view of Fig. 2.
Embodiment
Embodiment one
The logical steam plastic film capicitor of the present embodiment comprises by the cross section being the body 1 that corrugated PVC base bar self coiled coil consists of as shown in Figure 1, 2, 3, is lined with spiral support muscle 2 in this body 1.Spiral support muscle 2 is made of metal-cored 2-1 outsourcing plastic surface layer 2-2.Corrugated have three crest 1-1,1-2,1-3 and two troughs---the first trough 1-4, the second a trough 1-5.The first trough 1-4 among two trough 1-4, the 1-5 forms the acute angle the lowest point, and the second trough 1-5 forms the circular arc the lowest point.Coil the 3rd crest 1-3 outer surface in three crests of last circle of basic bar two adjacent rings and the internal surface of the primary peak 1-1 ' in three crests of a rear circle and fit by the hot melt adhesive sealing, and the applying that matches of the cross section gabarit of the internal surface of last circle the 3rd crest 1-3 and spiral support muscle 2.Body 1 interior formation double-head inner thread, the cylindrical of spiral support muscle 2 is supported in one of double-head inner thread.Pass silicone tube 3 in the envelope endoporus of spiral support muscle 2.
Because the envelope internal diameter of spiral support muscle is less than the minimum diameter of hose body, therefore after penetrating silicone tube in the flexible pipe, the PVC plastic tube body no longer directly contacts with silicone tube, thereby effectively avoided plastic tube body to break because excess Temperature softens, has simultaneously effect of heat insulation, intercept the heat radiation of body, significantly reduced the loss in the heat transfer process.And the rational interval of spiral support muscle is supported in the body crest, therefore makes bellows both have good intensity, has again desirable crooked pliability; Especially, the septal branch support structure of supporting rib and the reasonable setting of trough shape, so that when body is crooked, crest without supporting rib will be towards external expansion, therefore trough that can its both sides of connection also produces the trend of extending out, can not contact silicone tube because inside contracting, thereby guarantee to be subjected in the curved situation, have and avoid softening break, wear out fracture and heat insulation remarkable advantage.
In addition to the implementation, the present invention can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
