While water is kept cut off at the water hole in the distributing main by the core insertion shaft, the saddle snap tap to be replaced is replaced with the replacement saddle snap tap, then the core insertion shaft is removed. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water faucet exchanging method for exchanging an existing saddle water faucet with a new saddle water faucet due to the addition or deterioration of the water faucet, and a saddle used therefor. It relates to a diversion switch.

[0002]

2. Description of the Related Art Conventionally, when replacing a saddle water faucet, each part of the existing water faucet is closed, the water diversion branch pipe is removed, and a new water faucet is attached in the vicinity of the existing water faucet. In addition, it was based on the so-called burying method in which a new water passage was newly perforated.

However, in this method, since the existing water diversion branch pipe is used and the new water diversion hole is provided in the vicinity of the existing water diversion hole, a crack may occur between the old and new holes, and It included the problem that the pipe became weak in strength.

Therefore, as a countermeasure for this problem,
Insert a long rod-shaped water stop with a packer that can be expanded and contracted at the tip into the main water diversion hole through the upright hole of the existing water faucet, expand the packer and block the main water diversion hole Temporary stop After watering,
The practice of replacing diversion taps has come into play.

[0005]

However, in this method, a special water-stopper equipped with a packer capable of expanding and contracting at the tip is prepared only for the temporary water stoppage of the existing water diversion hole, and a complicated procedure is required. After temporarily stopping water at the old and new water taps,
Since the water diversion holes of the new water faucet will have to be expanded again, there is a problem that double labor is required.

Also, two types of equipment are available: a special water shut-off tool for only temporary water stoppage of the existing water diversion hole, and a perforation maintenance equipment for maintenance of expansion of the diversion hole of the new water faucet. There is a lot of waste in terms of work space and the technical aspects of the workers as well.

[0007]

DISCLOSURE OF THE INVENTION The present invention is to solve the above-mentioned problems, and replaces and separates the water faucet at once by using a device and a procedure which also serve as a perforator, a water stopper and a core mounting machine. The water hole can be expanded and maintained.

[0008] That is, by inserting an exchange machine in which a perforation drill is set from the upright insertion hole of the saddle water faucet to be exchanged, the water distribution main is perforated to renew the water passage hole, and further the core is attached to the exchange machine. Set the insertion shaft, install a close contact core in the renewal hole, and replace the saddle water faucet to be replaced with the saddle water faucet to be replaced while maintaining the water supply state of the water distribution main water passage hole by the core insertion shaft. After exchanging,
Remove the core insertion shaft.

The exchange has a shaft mechanism for holding a tip jig such as a drill and a core insertion fitting in a replaceable manner, and an exterior having a drainage structure for operating a water passage formed inside the shaft mechanism by surrounding the shaft mechanism. The mechanism is configured to be detachable, an adapter for fitting to the upper end of the water faucet is provided at the lower end of the exterior mechanism, and is structured to be fitted to the top of the saddle water faucet with the cap removed.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical cross-sectional view showing the setting state of the saddle water faucet in a state where the ball valve is opened. The water distribution main A is wrapped by the upper wrapping body 6 and the lower wrapping body 61 of the saddle, and the bolt nut 62 is attached. The main body 1 of the water faucet, which is fastened by the above-mentioned structure and is configured on the upper part of the upper holder 6, is attached to the water distribution main A.

The saddle water faucet has a connection opening 3 with a water supply branch pipe and a ball valve operating mechanism 4 on the side of the main body 1, and a device insertion hole 11 in the vertical direction through the ball valve 5 in the upper part, and a central portion. Further, the ball valve storage portion 12 for accommodating the ball valve 5 by engaging with the operation mechanism 4 and the lower part thereof is an upper wrapping body 6 mounted on the water distribution main A.

The upper wrapping body 6 of the saddle is attached to the outer periphery of the lower portion of the body 1 of the saddle water faucet, and the water faucet body 1 is attached to the upper surface of the water distribution main A by means of this and a gasket 14, and the bolt nut The main body 1 of the water distribution faucet is attached and fixed to the water distribution main A by fastening the lower holding body 61 with the 62.

The upper end is covered with a cap 13 and the lower end is joined to a water passage hole B formed in the water distribution main A through an upper wrapping body 6. Therefore, the cap 13 is removed and the ball valve 5
When the valve is opened, the device insertion hole 11, the water passage 51 of the ball valve 5 and the water passage B of the water distribution main A are communicated with each other, and the water of the water distribution main A is blown up as it is.

In replacing the water faucet, first, as shown in FIG. 3, the ball valve 5 of the existing water faucet C is closed to stop the water from the water distribution main A, and the tip jig of the shaft 71 is attached. The exchanging machine 7 in which the boring drill a having a larger nominal diameter than the existing water passage B is fitted to the joining mechanism 72 is fitted to the top of the water faucet with the cap 13 removed by the adapter 73.

When the ball valve 5 is opened after the exchange 7 is fitted,
The insertion hole 11, the water passage 51, and the water passage B communicate with each other to form a drill a
By rotating and lowering, for example, the existing water faucet water passage B having a nominal diameter of 20 mm can be expanded to a nominal diameter of 25 mm.

When the drill a is rotated and lowered, the water stop plug 81 provided on the exterior mechanism 8 of the exchange is opened, and the cutting debris generated by the enlarged diameter perforation is blown up by the water pressure of the water distribution main A and stopped. Allow it to drain through faucet 81. Due to this diameter-expanding perforation, the existing water distribution hole B of the existing water faucet is renewed to a nominal diameter of 25 mm, and rust bumps and the like are also eliminated.

When the diameter-expanding perforation is completed, the water stopper 81 is closed, the ball valve 5 of the existing water faucet C is closed, the exchanger 7 is temporarily removed, and the tip jig fitting mechanism 72 of the shaft 71 is closed. The drill a fitted to the above is replaced with the sticking core insertion rod b, the fitting core d is fitted on the tip thereof, and the exchanger 7 is fitted again to the top of the water dip.

Therefore, when the ball valve 5 is opened and the core insertion rod b is lowered until the core expanding structure 1b projects into the water distribution main A, the contact core d is renewed by the lower end flange portion thereof. It is locked to the inner edge of the water hole 1B and the sticking core d remains there and projects.

At the stage where the close contact core d is locked to the inner edge of the renewal water passage hole 1B, the lower end of the core expanding structure portion 1b formed by tapering the core insertion rod b has the renewed water passage of the close contact core d. By raising the core expanding structure 1b until it reaches the inner edge locking portion, the core expanding structure part 1b passes through the inside of the close contact core d to expand the diameter of the core and adhere to the inner edge of the renewal water passage hole 1B. The renewal water passage hole 1B is stopped by the 1b and the contact core d.

In this state, at the upper end of the exchange 7, the collar 82 for inserting the shaft 71 into the exterior mechanism 8 is removed, the exterior mechanism 8 is removed from the shaft 71, and the shaft 71 for stopping the renewal water passage hole 1B is removed. As shown in FIG. 5, the existing water distribution tap C is removed from the water distribution main A, leaving the water distribution main A, and a new water distribution tap D is attached to the removed portion via the gasket 14.

After installing the new water faucet D, the exterior mechanism 8 of the exchange 7 is attached to the shaft 71 and fastened with the collar 82,
The shaft 71 is raised to a position above the ball valve 5 of the new water faucet D, the ball valve 5 is closed, and the exchanger 7 is removed from the new water faucet D.

After removing the exchanger 7, the cap 13 is fitted to the new water faucet D, the water supply branch pipe is connected to the connection opening 3, the ball valve 5 is opened, and the existing water faucet C and the new water diversion are connected. The exchange with the stopper D is completed.

Next, the structure, elevating mechanism and operation of the exchange 7 will be described. The exterior mechanism 8 of the exchange 7 has an outer cylinder 83 and an inner cylinder.
It consists of 84, and the outer circumference of the inner cylinder 84 is a male screw 86 and the outer cylinder 83.
Internal threads 87 are engraved on the inner circumference of the bar handle.
The outer cylinder 83 is moved up and down along the outer circumference of the inner cylinder 84 by the rotation of 85.

When piercing the water distribution main A, the shaft 71 is inserted into the outer cylinder 83 through the inner cylinder 84,
A wrench hooking portion 74 on the top of the 71 is projected from the top of the outer cylinder 83 and fastened with a collar 82, fixed at the top with the outer cylinder 83, and a drill a is fitted to the shaft 71 by a fitting mechanism 72.

The exchange 7 fitted with the drill a is cap 13
When the bar handle 85 is rotated by fitting it to the top of the water faucet, the shaft 71 rotates with the outer cylinder 83 and the inner cylinder 84 is fixed to the top of the water faucet by the adapter 73. , Female screw corresponding to the turning direction of the bar handle 85
87 moves the male screw 86 forward and backward to move the shaft 71 up and down.

The shaft 71 is lowered and stopped until the drill a reaches the upper surface of the water distribution main A, and a ratchet handle is attached to the wrench hook 74 to directly rotate and lower the shaft 71 to the upper surface of the water distribution main A. It is configured to perforate.
Even if the tip jig is other than a drill, the operation is the same because it is basically moved up and down.

Since the present invention is configured as described above, it is possible to sequentially perform water stoppage, perforation, and water faucet exchange by using the exchanger 7, and avoid relatively large-scale construction such as water cutoff in the downstream of water distribution. The existing faucet can be easily removed and replaced with a new faucet with a saddle.
