Abstract

A method for cleaning pipes in a building by reciprocating a spring wire having a wire brush is provided to remove scales and rust in the pipe. A method for cleaning pipes in a building by reciprocating a spring wire(10) having a wire brush(4) includes the steps of: interposing a Y shaped joint between gate valves(1,2), and inserting the wire spring into the Y shaped joint; linking the wire brush to the spring wire; and reciprocating the wire brush through the pipe by winding and unwinding the wire spring wound around motor reels(5,6).

Description

A cleaning method of piping system in building by reciprocating movement of wire brush connected at spring wire}

Figure 1. Installs Y-shaped connector ③ between two dividing sides installed in the supply direction at the end of water pipe system in the building's indoor water pipe system, penetrates the spring wire 용 for customs, and connects the wire brush ④ for customs to the spring wire. It then represents a tubing customs system, in which the electrically driven wire winding reel ⑥ connected to both ends of the wire is alternately operated to cause the brush to reciprocate in the piping.

Figure 2. Is a spring wire and hot water injection system used to pass customs spring wire between piping conduits.

Open the plug of Y type connector ③, inject spring wire, and connect wire brush ④ when the wire comes out of Y type connector on discharge side.

Figure 3. Represents a method of connecting the spring wire and the wire brush by using a connecting ring, and the brush is floatingly connected rotatably during the reciprocating motion.

Economically removes rust and scale of indoor waterway pipes in buildings, restoring the water supply function of the pipes, reducing energy and improving water quality.

[Technical field to which the pipe belongs and its prior art]

Techniques for removing rust and scale of water piping in buildings include the following types of technologies, each of which has the following characteristics:

1. Magnetic field application

The magnetic field formed by the permanent magnet or the electromagnet is used to suppress the formation of scale in the pipe. It is easy to apply but the customs performance is weak.

2. Electromagnetic Field Application

DC power is used to supply electrons to water to reduce scale formation and rust. Compared to the high price, the function is similar to the magnetic field method.

3. Cathodic anticorrosion method

Supply the electrons to the pipe by using DC power and insert the electrode inside the pipe to supply the anticorrosive current. The anticorrosive function is excellent due to the stabilization of iron, but the anticorrosive distance is short.

4. Ultrasonic Method

Ultrasonic waves are applied to the running water to remove the adhered scale and the rust layer. It is effective for straight systems, but lacks in complex piping.

5. Metal ion supply method

By inserting a galvanic cell in the pipe, the cathode part dissolves and serves to drop off the existing scale when flowing into the metal ion. The electrons generated at this time are supplied to the pipe to help reduce rust.

6. How to make small particles of water

Well, it is a customs method using the principle of having a dissolving ability when water passes at high pressure through a passage of alternating anode disks. The performance is low compared to the high price.

7. Physical Customs by Pig Pass

Pig is passed through the tube at high pressure to remove scale and rust.

High pressures occur at small apertures.

8. Sand blasting method

It is a technology that allows high-pressure air to pass through as sand. The installation is complex and partial damage to the piping can occur.

9. Chemical cleaning

Acid is used to dissolve the rust and scale inside the pipe.

Environmental pollution occurs.

1. The customs process is simple and quick.

2. It is environmentally friendly.

3. The customs effect is excellent

4. Safe

5. It is economical

The present invention developed to achieve the above object consists of the following three steps.

Step 1: The part where the spring wire 관통 passes between the dividing side ① and the dividing side ② of the pipe

Figure 1. Insert Y-type fittings ③ before and after the dividing valve and inject the spring wire under pressure to penetrate it.

(When using the spring wire injector of Figure 2.

Step 2: connect the customs wire brush ④ to the spring wire

Step 3: Winding and unwinding the motor reel ⑤ and motor reel ⑥ alternately, customizing the customs wire brush ④ by reciprocating movement inside the pipe

(In customs, intermittently open the distillation valve so that the dropped scale is discharged.)

As described above, the present invention enables customs to be economically performed in a short time by inserting and reciprocating the customs brush between the dividing sides.

Compared with the existing customs process, the customs effect is faster and the customs time is shorter.

In addition, the present invention can be used as a supplementary pipe repair and painting in addition to customs purposes.

Claims (1)

Y type fitting for penetrating spring wire is installed in the pipe between the dividing side of the building indoor pipe and penetrates the wire by using a spring wire injector, and connects the wire brush to the spring wire to reciprocate.
