DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a water treatment apparatus having a butterfly valve according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 to 4 show a water treatment apparatus having a butterfly valve according to an embodiment of the present invention.

The butterfly valve 300 according to the preferred embodiment of the present invention,

A water treatment apparatus for a water supply pipe for supplying purified water from a water purification plant to a home,

A pipe body (100) having flanges (110) formed at both ends thereof;

A connecting pipe (200) having flanges (210) formed at both ends thereof;

A butterfly valve 300 secured by a coupling hole 310 for coupling the pipe body 100 and flanges 110 and 210 formed on the connection pipe 200;

An inspection port 122 having an inlet formed integrally with one side of the pipe body 100;

A cover 140 coupled to the pipe body 100 to open and close the charging port; And

And a scale filter (400) mounted inside the pipe body (100) through the inlet port to prevent scale and corrosion inside the water pipe.

Referring to FIG. 1, the pipe body 100 has a space in which the scale filter 400 is installed. The pipe body 100 is generally pipe-shaped and has flanges 110 formed at both ends thereof in the longitudinal direction.

Here, an electrostatic generating coating layer (not shown) is formed on the whole or a part of the inner wall of the pipe body 100 to maintain the surface roughness of the inner wall of the pipe body 100 at a high level so that the fluid rubs against the inner wall of the pipe body 100, And can be configured to continuously generate static electricity by the generation coating layer.

For reference, the electrostatic generating coating layer may be formed by a metal body of a pipe body 100 and a Teflon coating or a ceramic coating layer formed on the entire inner or outer surface of the pipe body 100.

The Teflon coating layer continuously generates static electricity with negative polarity in the fluid due to friction with the fluid, thereby activating the bonding with zinc ions in the water to spherical tissues to prevent corrosion. The Teflon coating layer is preferably formed to a thickness of about 0.8 to 1.0 mm by heat treatment at 400 ° C for 4 hours.

In this way, the static electricity generated by the friction with the fluid in the Teflon coating layer generates an electron flow, thereby preventing iron ions and the like in the water from reacting with oxygen ions, which is a cause of corrosion, to prevent and suppress corrosion.

The ceramic coating layer is preferably applied when the pipe body 100 is made of a metal such as zinc or aluminum and the ceramic coating layer is coated on a part of the surface to form static electricity together with the zinc ions As shown in FIG.

Also, it is preferable that the ceramic coating is made of alumina or silicon oxide as a main material, and the surface of the pipe body 100 is sanded to form fine irregularities before coating, thereby increasing the adhesive strength of the coating.

The ceramic coating is roughly divided into one coating, which is a first coating of ceramic paint, and two coatings, which is a transparent coating after a first coating. In the present embodiment, it is advantageous to generate a large amount of static electricity due to the friction with the fluid, because the two coating layers having a surface roughness superior to the one coating specification are advantageous.

The flange 110 formed at one end of the pipe body 100 is connected to the tap water pipe and the flange 110 formed at the other end is connected to one side of the butterfly valve 300, One side of the connecting pipe 200 is brought into contact with the other side of the connecting pipe 200.

A flange 210 is also formed at both ends of the connection pipe 200. A flange 110 formed at the other end of the pipe body 100 and a flange 210 formed at one end of the connection pipe 200 are fastened by a coupling hole 310. Between the flanges 110 and 210, The fly valve 300 is fixed.

That is, as shown in FIG. 2, the connection pipe 200, the butterfly valve 300, and the pipe body 100 are connected in this order from the left. A gasket 500 may be provided between the pipe body 100 and the butterfly valve 300 to prevent the fluid flowing in the pipe from flowing out. Between the connection pipe 200 and the butterfly valve 300, A gasket 500 may be provided for the same purpose.

In the circumference (diameter direction) of the pipe body 100, an inspection port 122 having a charging port is integrally formed. The inspection port 122 is a portion for mounting the scale filter 400 inside the pipe body 100, and a flange may be formed at an upper end thereof.

A cleaning polly pig (not shown) is installed in the water pipe through the inlet of the inspection port 122 and is transported as fluid pressure in the water pipe to clean and remove scales and water stains adhering to the inside of the water pipe. (Which may be formed of a polyurethane material having high elasticity so as to be elastically compressed and restored, for example).

A cover 140, which can open and close the inlet, is coupled to the upper portion of the inspection port 122 so as to detach the scale filter 400.

The cover 140 is formed with a flange (not shown) of a shape corresponding to a flange (not shown) formed at the inspection hole 122, and can be fixed by fastening means such as a bolt.

When the water treatment apparatus is inspected, the butterfly valve 300 is closed and checked. When the water treatment apparatus is abnormally detected, the inside can be inspected and repaired through the inspection opening 122, and excellent maintenance management is possible.

The butterfly valve 300 is a valve that is coupled to the pipe through which the fluid flows, and is opened and closed as the disc 340 rotates about the center line of the disc 340. The butterfly valve 300 typically includes a valve body 320, a stem 360 coupled along the centerline of the valve body 320, a stem 360 rotated by the stem 360, A disk 340 capable of blocking the flow of fluid passing therethrough and a seat 380 that keeps airtightness between the disk 340 and the valve body 320.

3 and 6, various types of butterfly valves 300 can be applied between the connection pipe 200 and the pipe body 100 according to the present invention, and the structure of the butterfly valve 300 Are the same as those normally used, and thus a detailed description thereof will be omitted.

The scale filter 400 and the rotating scale filter 400 'described below are used for preventing scale and corrosion inside the water pipe. The scale filter 400 and the scale filter 400' are disposed inside the pipe body 100 through the inlet formed in the pipe body 100, And the cover 140 is closed after mounting the scale filters 400 and 400 '(see FIG. 4).

In addition, since the inlet port of the inspection port 122 is opened and the scale filter 400.400 'is inserted and mounted, the fluid conveyed along the water pipe is contacted while passing through the scale filters 400 and 400', thereby removing the scale in the water pipe Or inhibit or prevent the occurrence of rust and corrosion.

In the present invention, the scale filter 400 may be configured to be fixedly mounted on a pipe body in various forms, for example, and rotated, and may be formed of tourmaline, , Cryptomeric, germanium, and charcoal.

The reason for using tourmaline in the present invention is as follows.

Tourmaline is the source of the most (-) electrons generated from natural stone. The negative (-) electrons are generally excellent for interfering with the binding of the (+) anion and (-) anions in the water, or for interrupting the molecular bond, ie, hydroxyl or interfacial action. For example, the use of soap in the hands of the hand oil in the grease is the principle of the-electron activity, that is, hydroxyl function or surfactant.

When such (-) electrons are mixed in the water, scale and corrosion can be prevented, and it is very effective in decomposing and removing scale and corrosion already formed in the inner wall of the pipe, and also exhibits a function of preventing corrosion.

As described above, in the present invention, a large amount of zinc ions for inhibiting the binding of inorganic salts and dissolved oxygen is generated, and zinc ions are electrostatically charged to accelerate the bonding with the inorganic salts, thereby blocking the binding between the inorganic salts and dissolved oxygen To prevent the occurrence of corrosion, and to generate (-) electrons to interfere with the binding of positive and negative ions in the water, thereby effectively decomposing and removing scales already generated.

Referring to FIGS. 3 to 6, the fixed-type scale filter 400 may include a lower guide ring 160 on which a scale filter 400 can be mounted, in the lower portion of the pipe body 100, The lower guide ring 160 may have a through hole formed along the periphery thereof.

That is, the lower part of the scale filter 400 is brought into contact with the upper part of the lower guide ring 160. The lower guide ring 160 may be detachably attached to the pipe body 100. In this case, a groove for mounting the lower guide ring 160 may be formed in the pipe body 100 .

An upper guide ring 180 for supporting the upper portion of the scale filter 400 may be formed on the inner upper portion of the pipe body 100. The upper guide ring 180 may have a through- have.

That is, the upper portion of the scale filter 400 is brought into contact with the lower portion of the upper guide ring 180. The upper guide ring 180 may be detachably detached from the pipe body 100. In this case, a groove for mounting the upper guide ring 180 may be formed in the pipe body 100 .

The upper guide ring may be formed at a lower portion of the cover 140. The upper part of the scale filter 400 mounted on the lower guide ring 160 formed inside the pipe body 100 is fixed by the upper guide ring 180 formed at the lower part of the cover 140 coupled to the upper end of the inlet .

Referring to FIG. 7, the rotating scale filter 400 'is installed on the same axis in a direction orthogonal to the fluid flow direction inside the pipe body 100 so as to face each other, And a pair of bearing members 600 made of a synthetic resin for generating static electricity by the bearing members 600.

The rotating scale filter 400 'is configured such that the rotating shaft 410 is formed on the upper and lower portions thereof and is rotatably assembled to the bearing member 600.

Therefore, since the rotating scale filter 400 'is rotatable by the bearing member 600 in the inside of the pipe body 100 through the inlet port, the rotating scale filter 400' is rotated by the fluid supplied into the pipe body 100, So as to generate static electricity or negative ions by friction, thereby preventing scale and corrosion inside the water supply pipe.

Specifically, the bearing members 600 are installed in a pair of bearing mounting grooves (not shown) formed to face the pipe body 100 and the cover 140 in the direction perpendicular to the fluid flow direction, .

The bearing member 600 may be made of a metal bearing if it is assembled while maintaining a hermetic structure with the rotating shaft 410 of the rotating scale filter 400 '. However, the bearing member 600 may be made of Teflon have.

When the bearing member 600 is made of the Teflon material, static electricity due to friction with the fluid contacting the bearing member 600 can be additionally generated while the rotatable scale filter 400 'is rotatably supported It is possible to provide advantages that can be obtained.

Therefore, the fluid can be freely rotated constantly or intermittently in a forward or reverse direction without any separate power supply or driving means by friction with the fluid supplied into the pipe body 100.

As described above, the present invention can be applied to an artificial driving means such as a driving motor (not shown) by a bearing member 600 provided in a direction orthogonal to the flow direction of the fluid inside the pipe body 100, So that it is possible to perform the forward rotation and the reverse rotation.

Accordingly, the rotating scale filter 400 'is constantly rotated or intermittently rotated in the forward and reverse directions corresponding to the flow of the fluid which changes frequently in the pipe, so that the entire outer surface of the rotating scale filter 400' It is possible to continuously generate a large amount of static electricity or negative ions.

In the above-described embodiment, the scale filters 400 and 400 'may be spherical or non-spherical, and may be made of a zinc material to emit negative ions.

The spherical shape has a circular cross section, and the non-spherical shape includes spherical shapes such as an elliptical shape and a long spherical shape, and has an outer shape that is less resistant to fluid flow, that is, a shape such as a streamline shape or a free-

When the scale filters 400 and 400 'are made of zinc, since the zinc ions are generated and discharged due to the contact of the fluid, the negative polarity remaining after being combined with the (+) polar inorganic salts contained in the fluid The dissolved oxygen in the band will not bind to other minerals.

Therefore, it is possible to prevent the corrosion of the inner wall of the pipe by preventing the bonding of (-) polarized dissolved oxygen and (+) polar inorganic salts Ca and Mg, which cause corrosion, will be.

Particularly, the rotating scale filter 400 'is rotated constantly or intermittently in the forward and reverse directions by the flow of the fluid, and the flow rate is also increased or decreased according to the increase or decrease of the speed of the fluid. So that a large amount of zinc ions can be produced.

As described above, since the scale filter 400 or 400 'according to the present invention uniformly contacts the fluid and the entire outer surface, the zinc ions are constantly generated corresponding to the flow velocity and continuously discharged in a large amount into the fluid, Dissolved oxygen can not be combined with other minerals having a positive polarity at all, so that it is possible to provide a water treatment apparatus that does not cause corrosion on the inner wall of the pipe at all.

2, the release port 322 may be formed around the valve body 320 of the butterfly valve 300. As shown in FIG. The release port 322 is provided to prevent the butterfly valve 300 from being separated from the pipe body 100 and the connection pipe 200. The butterfly valve 300 is connected to the pipe body 100, And is fixed by a coupling hole 310 coupled to the formed flanges 110 and 210.

Specifically, the binding port 310 is inserted into a through hole (not shown) formed in the flanges 110 and 210 as a fastening means such as a bolt, Thereby preventing the butterfly valve 300 from being detached. It is also possible to fix the bolts by using nuts or to fix them by forming threads in the through holes formed in the flanges 110 and 210. In addition, a plurality of the release bores 322 may be provided along the circumference of the valve body 320 as necessary.

If necessary, polyurethane lining coating of 3 to 5 mm thickness is applied to the inner surface of the valve body 320 of the butterfly valve 300, the flanges 110 and 210, can do. That is, it is possible to prevent self-corrosion (rust generation) due to polyurethane lining with corrosion resistance, abrasion resistance, impact resistance and ozone resistance, and thus to prolong the service life thereof.

In addition, due to the low coefficient of friction of the polyurethane material, the torque during operation of the disk 340 is small, so that the failure factor can be reduced. In addition, since the inside of the inspection hole 122 and the flange portion are lined with a polyurethane material, the inner surface of the inspection hole 122 is prevented from being corroded, and when the pipe is connected to the inspection hole 122, .

As described above, the water treatment apparatus provided with the butterfly valve according to the present invention provides the water treatment apparatus having the detachable butterfly valve installed in the water supply pipe, so that when the butterfly valve 300 is broken or broken Easy to repair and replace.
