Embodiment 1

[0095] figure 1 is a perspective view of a polyethylene spiral pipe according to a first embodiment of the present invention, and figure 2 Yes figure 1 A cutaway view of a portion of the helical tubing shown. As shown in the figure, the helical tube according to the present invention includes a hard helical part 10 and a soft helical part 20 assembled with each other.

[0096] The rigid helical part 10 is made of polyethylene and extends in the shape of a helical spring, wherein the helical gaps between the turns of the helical spring have a uniform width. In a sectional view, the rigid helical member 10 includes a protruding portion 14 protruding upward with a corner and a flange 12 extending laterally from a lower end of the protruding portion 14 .

[0097] In addition, the soft spiral member 20 has a belt shape, and is made of polyethylene tarpaulin formed by coating a polyethylene woven cloth. The soft helical part 20 is arranged along the helical gap between the heli...

Embodiment 2

[0110] Figure 5 and Image 6 Respectively, they are sectional views of main parts of a spiral tube according to another embodiment of the present invention. As shown, the rigid spiral member 30 includes a protruding portion 34 that protrudes upward and has corners to form a rectangular space within the protruding portion 34 , and a flange 32 that extends laterally from a lower end of the protruding portion 34 . This structure gives the rigid helical member 30 a stronger structure, thereby preventing the opposite inner surfaces of the tube from sticking to each other and maintaining the shape of the tube even under the strong pressure of the conveying water.

[0111] In the case where the hard spiral member 30 has the above structure, as Figure 5 and Image 6 As shown, the side ends of the soft helical member 20 can be connected to the inner surface or the outer surface of the flange 32 of the hard helical member 30 . In this case, preferably, the high density polyethyle...

Embodiment 3

[0114] Figure 8 and Figure 9 Shown is a spiral pipe according to yet another embodiment of the present invention, which is used as a water supply pipe having spray holes.

[0115] That is, the soft spiral member 20 is made by coating the polyethylene woven cloth layer 23 with polyethylene coatings 21, 25, and 27, respectively having a plurality of injection holes 21a, polyethylene coating holes 25a, and polyethylene Coating hole 27a. In this case, water can be discharged or introduced into the helical tube through the gap between the weft yarn and the warp yarn of the polyethylene woven cloth layer and the spray holes 21a, 25a, and 27a formed in each polyethylene coating layer, so that this Spiral pipe can be used as water supply pipe.

[0116] Although the spiral tube according to the present invention provided by the above description is used for conveying water, the spiral pipe according to the present invention can also be used as a gas conveying pipe. In the latter ...

Abstract

Disclosed is a spiral hose which includes a hard spiral member made from polyethylene and a thin soft spiral member made from polyethylene tarpaulin, and which can be used not only as a general hose but also as a gas duct or a watering hose. The spiral hose is wound in a spiral shape to have flexibility. The spiral hose comprises: a hard member made from polyethylene, which is wound in a spiral shape with a uniform spiral gap formed between turns of the hard member, and a soft member having a shape of a band and being formed of polyethylene tarpaulin, the soft member being disposed along the spiral gap while lateral edges of the soft member are fixed to portions of the hard member, which are disposed oppositely on both sides of the spiral gap.

Description

technical field [0001] The present invention relates to a spiral pipe, in particular to a spiral pipe comprising a hard spiral part and a thin soft spiral part, wherein the hard spiral part is made of polyethylene, and the thin soft spiral part is made of polyethylene tarpaulin (polyethylene tarpaulin). tarpaulin), this spiral pipe can be used not only as a normal pipe, but also as a gas delivery pipe or a water supply pipe. Background technique [0002] Typically, spiral tubing is used for pumping and transporting liquids such as water. This is to prevent water from leaking from the entire wall of the spiral pipe, and to prevent the inner surfaces of the spiral pipe from adhering to each other due to the pressure of conveying water, and to have flexibility, compared with ordinary pipes. [0003] Commonly used spiral pipes include hard spiral parts and soft spiral parts, wherein the hard spiral parts protrude outward and withstand the water pressure in the spiral pipe, whil...
