JPH0648233Y2 - Three-way adjustment fitting for pipe - Google Patents

Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a steel pipe, a cast iron pipe, and a short pipe joint for a cast steel pipe, which are provided with an inner lining or a inner coating for transporting fluids such as seawater and chemical liquids. Relates to an adjustment joint that can be expanded and contracted in all three directions.

[0002]

2. Description of the Related Art Conventionally, in the case of a pipe which is required to be lined or coated on the inner surface of a pipe of this type, when a branch pipe is provided from the pipe, a three-way joint including a branch pipe portion can be aligned on site. It is known that the three-way mate joint is manufactured by manufacturing (hereinafter, referred to as a three-way mate joint) and the inner surface of the three-way mate joint is lined or coated.

[0003]

[Problems to be Solved by the Invention] According to the prior art, the three-way mating joint is a pipe joint manufactured by actual fitting at the site, but if the actual fitting is wrong or temporary piping is completely fixed. Therefore, if the pipe is tightened with U-shaped bolts and nuts, the dimensions will be different from the measured values at the time of actual matching, and it may be necessary to fine-tune the three-way fitting by flame processing such as welding. In this case, there is a problem in that the lining or coating on the inner surface of the three-way joint is burned out by flame working.

The present invention has been made in view of the above problems of the prior art, and an object thereof is a flame capable of absorbing a dimensional error caused by completely fixing the pipe. It is an object of the present invention to provide a three-way adjusting joint for a pipe that does not require any processing.

[0005]

In order to achieve the above object, a three-way adjusting joint for a pipe according to the present invention comprises a T-shaped T-piece having a branch pipe, a straight pipe or a curved pipe at one end. It has a connecting flange and a flanged short tube having a threaded end on the other end, a threaded socket screwed into the threaded portion of the flanged short tube, and an O-ring.
The lining and the inner surface of the flanged short pipe are lined or coated.

[0006]

[Function] The short pipe with flange and screwed socket are T
Since the rotation of the piece is facilitated and the direction of the branch pipe is selected to be an arbitrary angle with respect to the straight pipe over the entire circumference, it also has a margin for absorbing the T piece into the flanged short pipe. The dimensional error of the flanged short pipe gap can be absorbed.

[0007]

EXAMPLES Examples will be described with reference to the drawings.

In FIG. 1, a T-piece 1 having a polylining on its inner surface is inserted into a screw-in socket 8.

An O-ring 6 is mounted on the outer circumference of the T-piece 1 and inside the screw-in socket 8.

The T-piece 1 is inserted into the side of the short tube 2 with a flange on the side opposite to the flange where the threading 4 is applied.

The direction of the branch pipe of the T piece 1 is adjusted, and the screwed socket 8 is fastened to the flanged short pipe 2.

Similarly, the branch pipe is also inserted or inserted into the screwed socket 9, the O-ring 7 and the flanged short pipe 3 to adjust the length of the flanged short pipe 3 and then the screwed socket 9
Is fastened to the flanged short pipe 3.

[0013]

Since the present invention is constructed as described above, it has the following effects. Since the distance between the flanges at both ends can be adjusted by adjusting the wrap length of the T-piece 1 inserted into the flanged short pipes 2 and 3, the T-piece 1 and the flanged short pipe can be preliminarily formed on the inner surface of the pipe. If the lining is applied, the pipe having the branch pipe can be joined without damaging the inner surface lining.
