Description

Anti-twisting, high pressure resistant flexible pipe

Technical field

This utility model relates to plastic flexible pipe field, is specifically related to anti-twisting, high pressure resistant flexible pipe.

Background technology

The flexible pipe that PVC garden sprinkle and furniture clean in the market, be all with inner tube, outer tube and inner tube with Clip one layer of fiber between outer tube and strengthen the frame mode of net.Net strengthened by middle fiber, has multiple in the market Different structure mode, a kind of is traditional wound web line structure mode；One is one layer of straight burr of crocheting or twill cellular fibers The frame mode of net；Another kind of by winding and crocheting combination.Existing wound web line structure is not well positioned to meet PVC The requirement of strength of flexible pipe.

The first traditional winding net mode, as it is shown in figure 1, include internal layer body 1, outer layer body 3, single 1 (a).Simply being wrapped on interior tube body surface by single, netting twine is loose and simple intersection, and infall does not forms node, therefore When winding pipe, product easily causes folding point and distortion, has influence on liquid conveying, causes the shortcomings such as winding inconvenience simultaneously.

The second straight burr or twill cellular fibers net, as shown in Figure 2 and Figure 3, be through cloche, by crocheting Mode is formed.Wherein Fig. 2 is straight burr crocheting net hose construction schematic diagram, including internal layer body 1, outer layer body 3 and straight burr honeybee Nest net 1(b).Fig. 3 is twill crocheting net hose construction schematic diagram, including internal layer body 1, outer layer body 3 and twill honeycomb Shape fiber net 1(c).The netting twine of this net forms node at infall, makes net form an overall structure, although to improve The distortion power of flexible pipe, but can elongate owing to being formed after net grid is under pressure, easily make the tube swelling deformation of PVC garden, Cause garden pipe to bear internal pressure capability to decline, have influence on PVC garden pipe service life.

The third uses the former to combine, as shown in Figure 4, Figure 5.Wherein Fig. 4 is traditional wound netting twine and straight burr crocheting net Combine hose construction schematic diagram, including internal layer body 1, middle level body 2, outer layer body 3, single 1(a) and straight burr cellular Fiber net 1(b).Fig. 5 is that traditional wound netting twine combines with twill crocheting net hose construction schematic diagram, including internal layer body 1, middle level body 2, outer layer body 3, single 1(a) and twill cellular fibers net 1(c).Although improve PVC garden pipe Bear intrinsic pressure, but the anti-twisting ability of flexible pipe can be reduced, make PVC hose when actually used, it has not been convenient to operation, especially long distance From tortuous circuit.
