Abstract

The utility model discloses a woven wire extended-play net which uses a twill structure with a micro clearance (21) among the woofs (2). The longitudinal density of the extended-play net is much bigger than the latitudinal density, namely the product of the wire diameter of the longitude (1) and the total number of the longitude (1) is equal to or one to two times bigger than the net width. The woven wire extended-play net of the utility model can both satisfy the demand of the density value and can improve the whole fastness of the net surface.

Description

Metal wire knitted fine groove net

Technical field:

The utility model relates to a kind of woven wire cloth, especially a kind of metal wire knitted fine groove net that is used for the liquids and gases purification filtering.

Background technology:

In wire braid, the same tram of every organizine (or tram) (or organizine) is interweaved once, just forms an intertwined point.Only intersect and the variation of generation intersection as warp, tram, then this intersection point is called interlacing point.Do not have when repeating when the ordering that interweaves in certain section of warp-wise or broadwise intertwined point and interlacing point, this section promptly constitutes a tissue circulation, counts interweaving in tissue circulation and the tissue sum of counting is called and organizes period.Common metal silk braid is divided into square hole net and fine groove net, and the mesh of square hole net is square, and thread count is identical; The fine groove net is folded net or seat shape net again, generally through rare filling density, does not have the gap between the tram, and liquid or gas are by the slit pressure filtration through place, tram intertwined point.The fine groove net has plain weave structure and two kinds of structures of twill structure.In plain cloth, just mutually intersect every one through tram and to change once, in a tissue circulation, organizing period is 2 forever, counts and interweaves because of tissue and count equally, the whole fastness of fabric is strong.But do not produce floating long line, the mutual extrusion contact-making surface of line is little, so the density value of fabric is low, its filtering degree is just low.In twills, organize period forever greater than 2, and count, produce floating long line greater than interweaving, the mutual extrusion contact-making surface of line is big, so the density value height of fabric, the filtering degree height is counted under the identical condition interweaving, organize period big more, floating long line is long more, and density is big more, and the whole fastness of fabric is just poor more.In sum, plain weave thing and bias fabric, there are inverse relation in its density and whole fastness.In addition, the fine groove net adopts plain weave or twill weave, owing to do not have the gap between the tram, adjacent tram tightly sticks together, and parallel can force warp to have a certain amount of elongation to extend during braiding, and wire side tension force is affected, and has reduced whole fastness.

Summary of the invention:

The purpose of this utility model is to provide a kind of metal wire knitted fine groove net, can satisfy the requirement of density value, can improve the whole fastness of wire side again.

For this reason, the utility model changes the fine groove pattern at the characteristics of common fine groove net filling density, adopts two kinds of concrete technical schemes:

First kind of scheme: metal wire knitted fine groove net belongs to the fine groove pattern, and promptly net adopts twill structure, and slight clearance is arranged between parallel.

As a kind of improvement, the parallel gap satisfies condition

, wherein δ is a gap value, and d is parallel line footpath, and unit is a millimeter, and m is the radical of parallel in the broadwise per inch length, and 26＜dm＜50.8, m＞1.

Second kind of scheme: metal wire knitted fine groove net belongs to reverse fine groove pattern, and promptly the warp-wise density of net is much larger than latitudinal density, and promptly the product of warp line footpath and the total radical of warp is equal to or greater than wide 1～2 times of net.

First kind of technical scheme, because the utility model adopts twill structure, can guarantee that net has higher density, simultaneously owing to leave the gap of trace between the parallel, form space fine groove net, warp is not stretched by parallel during braiding, makes wire side tension force unaffected, has correspondingly improved the whole fastness of wire side.Realize both satisfying high intensity values, improved the whole fastness of wire side again.

Second kind of technical scheme, the product of warp line footpath and the total radical of warp are equal to or greater than wide 1～2 times of net, form rare through crammed, make net have oppositely overflowing property, become reverse fine groove net, under the prerequisite that guarantees density value, the longitudinal pulling force and the intensity of wire side significantly improve.

Fig. 1 is a kind of embodiment schematic diagram of the utility model.

Fig. 2 is the schematic diagram of the another kind of embodiment of the utility model.

Fig. 3 is a wire netting left view shown in Figure 2.

The specific embodiment:

Embodiment 1: as shown in Figure 1, the utility model metal wire knitted fine groove net is made up of warp 1 and parallel 2, and net adopts twill structure, and organizing period is 4, warp, parallel are comparatively speaking, warp 1 is rare, and parallel 2 is close, and the gap is bigger between promptly adjacent two warps 1, mutual extrusion between adjacent two parallels 2, gap 21 is less, and the floating long line 22 of parallel 2 formation, so the density value of net is higher.Owing to leave slight clearance 21 between the parallel 2, overcome gapless shortcoming between the common fine groove net parallel 2 simultaneously, warp 1 is not stretched by parallel 2 during braiding, and parallel 2 interweaves back and forth around warp 1, and wire side tension force and whole fastness are also increased.Gap value between the parallel 2 will suit, and gap 21 is excessive or too small, and whole fastness of wire side and tension force are affected.Parallel 2 gaps preferably satisfy condition

Embodiment 2: Fig. 2, Figure 3 shows that the fine groove net that weaves with the plain weave mode, it organizes period is 2, and the spacing of being separated by between the parallel 2 is bigger, and warp 1 tightly is close together each other, its warp-wise density value height, the product of warp 1 line footpath and warp 1 total radical is equal to or greater than nets wide 1～2 times.

Claims
