Abstract
The utility model provides a new gas helix pumping and discharging pipeline, which is provided with a pipe body and a ring flange. The pipe body is fitted and connected with the ring flange, which is formed by using one edge of a cold-rolled steel coil to occlude and ring joint the corresponding edge in helix and element rests generated by occlude and ring joint the cold-rolled steel coil all protrude forward to the external diameter of the pipe body. The utility model is characterized in that: one edge of the cold-rolled steel coil coils as a U shape which ring joints with the other U shape coiled by the other edge to form the element rests. The technical proposal has the advantages that: the occlude area for U-shaped coils occluded is larger than that fro arc coils occluded, thus capability of bearing larger tensile force, which, therefore, enables the gas helix pumping and discharging pipeline have higher intensity.
Description
Affiliated technical field
The utility model relates to a kind of architecture advances to spiral gas extraction pipeline.
Background technique
Spiral gas extraction pipeline is widely used in fields such as air-conditioning, fire damp extraction, the existing spiral duct of being made by cold-rolled steel coils has overcome shortcomings such as original inorganic glass-fiber reinforced plastic poor toughness, fragility are big, yielding, damp suction surface halide accumulation, poor water resistance, and shortcoming such as seamless steel pipe weight is big, installation difficulty is high, poor water resistance, corrosion-resistant, wall unevenness are even, and the polyvinyl chloride pipe is easily aging under moist, hot environment, under the northern cold cold environment pipe shaft easily break, shortcoming such as poor fire.
As shown in Figure 1, existing spiral gas extraction pipeline has body 1 and flange plate 2, and body 1 and flange plate 2 cooperate and connect.Body 1 is formed to enclose to connect with its corresponding sides spiral interlock on one side by cold-rolled steel coils 10, and occlusion structure is seen Fig. 2.Cold-rolled steel coils 10 spiral interlocks are enclosed and are connect the convex tendon 11 that is produced and all protrude to body 1 external diameter.
Occlusion structure as shown in Figure 2, the circular arc type interlock that the circular arc type that one side turnup of cold-rolled steel coils 10 becomes becomes with its another side turnup and become convex tendon 11.Convex tendon 11 outward appearances are illustrated in figure 3 as arc.
Because spiral gas extraction pipeline application is at special dimensions such as air-conditioning, fire damp extractions, require very high to its tightness, interlock place of the spiral duct of said structure is the mutual interlock of circular arc type flange, be subjected at spiral duct under the situations such as impact, stretching, extruding, interlock place may be stressed excessive and break away from, phenomenon of rupture.
Summary of the invention
The utility model provides novel spiral gas extraction pipeline, and its purpose solves the shortcoming that prior art exists, and provides a kind of intensity higher pipeline.
The technological scheme that its technical problem that solves the utility model adopts is:
Novel spiral gas extraction pipeline, have body and flange plate, body and flange plate cooperate and connect, body is formed to enclose to connect with its corresponding sides spiral interlock on one side by cold-rolled steel coils, the interlock of cold-rolled steel coils spiral is enclosed and is connect the convex tendon that produced and all protrude to the body external diameter, it is characterized in that: the U type interlock that the U type that one side turnup of cold-rolled steel coils becomes becomes with its another side turnup and become convex tendon.
The usefulness of technique scheme is: the mutual interlock occlusal surface of U type turnup is bigger than the occlusal surface area of the mutual interlock of existing circular arc type turnup, thereby can bear bigger pulling force, and spiral duct so intensity are higher.

Embodiment
As shown in Figure 4, spiral gas extraction pipeline of the present utility model has body 1 and flange plate 2, and body 1 and flange plate 2 cooperate and connect.Body 1 is formed to enclose to connect with its corresponding sides spiral interlock on one side by cold-rolled steel coils 10, and occlusion structure is seen Fig. 5.Cold-rolled steel coils 10 spiral interlocks are enclosed and are connect the convex tendon 11 that is produced and all protrude to body 1 external diameter.
Occlusion structure as shown in Figure 5, the U type interlock that the U type that one side turnup of cold-rolled steel coils 10 becomes becomes with its another side turnup and become convex tendon 11.Convex tendon 11 outward appearances are illustrated in figure 6 as quadrilateral.
