Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soft hose piping construction method used for circulating a fluid (air, liquid, etc.).

[0002]

2. Description of the Related Art As is well known, in a piping structure in which a curved portion is formed in a soft hose, the curved portion is deformed or bent and fluid flow becomes poor. Therefore, usually, a wire-containing hose in which wires are attached in a spiral shape is used to prevent the curved portion from being deformed or bent. However, the wire-containing hose is liable to leak fluid at the connection portion of the hose, and requires complicated and advanced construction techniques to prevent the leakage, resulting in poor workability. In addition, prices are relatively high.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described . The soft hose piping construction method of the present invention is realized, for example, in a piping structure having a curved portion such as a liquid filter. That is, since the piping structure of this liquid filter has an overflow path between the treated water outlet of the liquid filter and the treated water tank, a soft hose made of synthetic resin (for example, nylon) having a flexible piping material is used. Hose) is used. Then, in order to avoid the overflow path, a predetermined curved portion is formed on the soft hose to form a piping structure that bypasses the overflow path.

According to the soft hose piping construction method of the present invention, in the piping structure, first, from the treated water outlet,
Cutting the soft hose required before the treated water tank to a predetermined length. Then, a commercially available coil spring having an outer diameter that can be freely inserted into and removed from the soft hose is set to a predetermined length ( front
Cut to length) corresponding to the serial curved portion, fitting the coil spring to a position of forming the curved portion of the flexible hose. Next, as a means for preventing the coil spring from moving inside the soft hose, the coil spring is fixed from the outside of the soft hose with, for example, a tightening band. When fixing this,
From the outside of the soft hose to the clamping vanes.
Each one with one of the coil springs
Location, for example the central part, from the outside of the flexible hose
Secure with attached band. Thereafter, the soft hose to form a predetermined curved portion, the溢路piping to bypass the, respectively connected with a tightening band both ends to the inlet of the treated water outlet and the treated water tank.

[0008] As described above, the pipe construction method of the soft hose of the present invention, using inexpensive the soft hose with a marketable, when forming the bending portion to the soft hose, before
Serial fitted commercial of the coil spring to bend, the <br/> the coil spring is subjected to a means for preventing the movement in the soft hose, deformation and bending preventing the flow of fluid to the curved portion Can be reliably prevented. Further, since the wire does not enter the connecting portion unlike the conventional case, fluid does not leak from the connecting portion. Further, according to the present invention, it is possible to form a curved portion that does not cause inconvenience due to deformation or bending, and it is possible to realize a compact piping structure. Furthermore, since in combination with the soft hose with commercial of the coil spring are marketable inexpensive and good workability,
The piping structure is extremely efficient.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is an explanatory view schematically showing a piping structure in which a liquid filter according to the present invention and a processing liquid tank are connected by a soft hose.

In FIG. 1, obstacles 5, 6, 7 such as other components are interposed between the outlet 2 of the liquid filter 1 and the inlet 4 of the treatment liquid tank 3. Accordingly, the liquid filter 1 and the processing liquid tank flexible made of a synthetic resin 3 and piping materials for connecting the flexible hose 8 (e.g., nylon hose) with, the respective obstacle 5,6,7 In order to avoid it, the pipe structure has a predetermined curved portion 9.

The soft hose piping construction method of the present invention is
In the piping structure, first, the outlet 2 of the liquid filter 1
From cutting the soft hose 8 required to the inlet 4 of the processing liquid tank 3 to a predetermined length. That is, it is cut into a length necessary and sufficient for forming the curved portion 9. Then, in the commercial coil spring 10 having a Hamada' freely outside diameter in the soft hose 8 is cut into a predetermined length (length corresponding to the bending portion 9), the soft hose 8 the coil spring 10 It is fitted to the position where the curved portion 9 is formed. Next, as a means for preventing the coil spring 10 from moving in the soft hose 8, for example, the tightening bands 11 and 11 are used to soften the soft hose 8.
Both ends of the coil spring 10 are fixed from the outside. Thereafter, predetermined the said flexible hose 8 the bending portion 9
The formed (see FIG. 1), the piping to bypass the respective obstacle 5,6,7, respectively inserted into both ends to the inlet 4 of the fluid filter 1 of the outlet 2 and the processing liquid tank 3, The flexible hose 8 is fastened from the outside using a fastening band (not shown) to complete the piping.

Next, another embodiment for preventing the movement of the coil spring 10 will be described. In the embodiment of FIG. 1, the both ends of the coil spring 10 shown for the case of fixing by using the fastening band 11, 11 has been described, the invention is not limited thereto, the coil One position of the spring 10, for example, the curved portion 9
Also the central portion of only be fixed by the fastening bands 11,
It is suitable depending on the implementation.

[0013] As described above, according to the pipe construction method of the soft hose of the present invention, using inexpensive the soft hose 8 are marketable, when forming the bending portion 9 in the soft hose 8, wherein fitted commercial said coil spring 10 of the bending portion 9, since the coil spring 10 is fixed by the fastening bands 11 from moving inside the soft hose 8, the coil spring the soft hose 8 to the inside 10 can form the bending portion 9 which is interposed, it is possible to prevent the deformation and bending preventing flow of fluid. Further, since the wire does not enter the connecting portion unlike the conventional case, liquid does not leak from the connecting portion.
And you can surely pipe with simple construction work,
The workability is good and the piping structure is extremely efficient. Furthermore, since in combination with the carp <br/> le spring 10 of the commercial and the soft hose 8 are marketable, inexpensive, and simple piping structure.

[0014]

According to the present invention, when a curved portion is formed on a soft hose, it is possible to prevent the curved portion from being deformed or bent. Further, it is possible to realize an extremely efficient piping structure, which is less expensive than the conventional wire-containing hose and has no leakage from the connecting portion. Furthermore, since a curved portion that does not cause inconvenience due to deformation or bending can be formed, it is possible to realize a compact piping structure.
