Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a cleaning tool for scrubbing the inner surface of a fluid conduit.
related. Although this cleaning tool is described below in connection with metal and wood pipes, pipes used in pipes, oil equipment, and chemical equipment may also be physically cleaned by this cleaning tool.

-3 Concrete pipes can also be processed.

Water mains are particularly susceptible to problems in areas where the water contains large concentrations of ferrous and ferric salts; the iron content of these salts is often visible in water samples as flocculated sludge. . This metal tends to adhere to the surfaces of the tubes in the mesh arrangement and ultimately prevents the valves within the tubes from closing completely.

In one known method this is a rigid shaft.

A bell-shaped cleaning tool consisting of a pair of steel disks and a rubber washer tightened between the two disks is used to hydraulically clean the pipe.
Removed by pecking each part in turn. This cleaning tool is unreliable in its use.

This can result in blockages in portions that are not part of the pipeline network or in small obstructions such as protruding main cocks or gate valves.

All pipe sections must be drained prior to cleaning operations.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning tool that allows the plow to pass through parts and obstacles. Rounding The cleaning device for scrubbing the inner surface of a fluid conducting tube provided by the present invention has at least two disks of elastic material, preferably parallel to each other, suitable for being force-fitted into the tube; In this, the discs are connected to each other by elastic supports, and the discs can be passed together in such a way that no mechanical interference occurs between the edges of the discs when the cleaning tool passes over the area. The number of 0 disks that are separated from each other when achieved is #i3.4゜5.4,
7. mouth, 9.1G, 11.12 or more, but depending on the heading, 5 or 6 yen 1
The O-disc, in which N is desirable for operation, can be made thinner towards the circumference to assist the OII head during its passage. It has been found that when the disc has a single radial slit, the entire cleaning tool flexes during use (an unnecessary fluid pressure drop may occur in the case of a circular cut). ), the slits can be arranged straight with respect to each other in the axial direction, but instead of 0, successive slits can be arranged at 90 degrees with each other, and this is because the passage of liquid is prevented by such alternate disks. desirable.

Advantageously, the cleaning implement is molded in one piece or is molded as a double article and then divided. The disks are molded in a parallel shape to allow for easy opening and closing of the mold, but this relationship is not essential and the disks may be interchangeable to the extent that they do not interfere with the cleaning tool's performance when bent. can be located in a plane that makes an angle to The hardness of the rubber arm may be about 90.

Embodiments of the present invention will be described below with reference to the drawings.

The cleaning tool shown has a nominal rating of 1501119t! It is used for the main part of the hole and consists of a single rubber molding having a length of 525 mm and a shaft 2 of diameter isw. This has 5 01 disks 4 and the diameter of the 4 disks is 15511 m. Each disk is thinner from the axis to the circumference, υ, its thickness is 10 days or less in mm and 1511j in B), and this structure improves the deformation properties. Each disk is spaced 801 mm apart from each other, measured from 1 km flat to the flat surface. A semi-backward slit 6 extends in the north-south direction from the horse to the shaft in each disc.

In another embodiment used for a 4 inch (approximately 100 IllB) diameter water main, the shaft is 2iSQtll long and 35
-〇m-. This K has a disk with a diameter of 104 days and is cut into 4 thin layers. Each disc is thinner than 1k toward the periphery as shown in the diagram.
E% Takasamu is 2 cranes, B is 77 villages, and it is 4210 square meters apart from the neighboring disk-sha flat picture.

In No. 1, the disc 4 does not change in thickness, but has a cross-shaped glue. A multi-stranded wire cable 1o serves as an axis, and the discs 4 are separated by a collar 12. All of these are loosely held together by a pair of O bronze collars 14 to allow sufficient flexing.

When attempting to clean a pipe, such as a water main, the procedure is as follows. In the street to be cleaned, the pipe is
meters and at the closed end it is disconnected 5 meters from another valve. All domestic water pipes are isolated and pipe 75081
part is removed.

The cleaning tool is inserted into the tube so that it fits snugly into the tube (preferably the cleaning tool is tapered), and the tubes are reconnected by a gibault fitting. 9.A flexible hose can be connected to the receiving end to avoid any inherent damage caused by water.Then the valve is opened (approximately 4 turns depending on the head) and the water and/or air is pumped into the tube. Push the cleaning tool forward. Cleaning - Once the tool exits the open end, the IK mains are cleaned and then the tubes are reconnected and chlorinated before use again.

It has been found that the embodiment described above provides a good scraping effect in a single pass, and is capable of deflecting along bends in the pipe and passing through the valve! passes through obstacles in the lead pipe,
It has many advantages in that it resists undesirable honeycombing that would otherwise cause cleaning tools to adhere to the tube.

Although the cleaning tool has been described for use on water mains, it can obviously also be used in chemical plants, petrochemical equipment, gas lines, etc.
