Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the sample tubular construction that has oblique wound of the present utility model.
As shown in Figure 2, the sample tubular construction that has oblique wound of the present utility model, this sample pipe 1 structure includes on the inside surface and outside surface of distance sample tube end certain distance, be carved with parallel wound 5 parallel and the vertical wound 2 vertical with sample pipe bus with sample pipe bus, the inside and outside surface of described sample pipe is provided with oblique wound, tiltedly hinder and include dextrorotation and tiltedly hinder 3 and left-handed oblique wound 4, tiltedly the angle of inclination of hindering is 11 °, 22 °, 45 °, 67 ° a kind of.Described oblique wound be shaped as a U-lag, the U-lag length direction is curved.
Be provided with left-handed oblique wound 3 and dextrorotation at the outside surface of described sample pipe and tiltedly hinder 4 each one, be provided with left-handed oblique wound 3 and dextrorotation at the inside surface of described sample pipe and tiltedly hinder 4 each one.
On the longitudinal direction of described sample pipe, described oblique wound and tiltedly hinder between at a distance of 〉=200mm.
The oblique wound that described sample pipe internal surface is provided with and the distance≤1500mm of sample pipe pipe end.
On sample pipe longitudinal direction, tiltedly hinder with tiltedly hinder between be greater than certain distance apart, big usually and equal 200mm.Each oblique wound is not placed on the blind area of sample pipe, i.e. pipe end arrow A place is except vertical wound and the parallel wound.At the sample tube outer surface, left-handed oblique wound 3 and dextrorotation are tiltedly hindered 4 and are respectively established one; At the sample pipe internal surface, left-handed oblique wound 3 and dextrorotation are tiltedly hindered 4 and are respectively established one, internal injury and pipe end, the i.e. distance≤1500mm of tube head or pipe tail.
