Abstract

PURPOSE:To provide a piping joint whereby man-hour and part cost are reduced and water leakage is prevented. CONSTITUTION:In a piping joint provided with a flange 3 of which surface is perpendicular to the axial direction of a pipe 2 at one end of the main (pipe) 2, the other end of the pipe 2 is bent at right angle relative to the axial direction to form an elbow part 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe joint for connecting a faucet fitting such as a faucet and a water supply pipe.

[0002]

2. Description of the Related Art Conventionally, as a pipe joint, there is a so-called flange joint as disclosed in, for example, Japanese Utility Model Laid-Open No. 167294/1985.

In this type of piping joint, a flange for attaching to a wall surface is provided at one end of the pipe.

[0004]

By the way, the water supply pipe of a house or the like is often a so-called start-up pipe. In this case, the other end of the pipe joint and the water supply pipe are used. And are connected by a separate elbow pipe. Therefore, the number of man-hours at the construction site and the cost of parts have increased. In addition, there is a problem that water leakage may occur from a connecting portion between the pipe joint and the elbow pipe.

The present invention was created in view of the above problems, and it is an object of the present invention to provide a pipe joint which reduces the number of working steps and prevents water leakage.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a pipe joint having, at one end of a pipe, a flange whose flange surface is a surface orthogonal to the axial direction of the pipe. In the second aspect, the other end of the pipe is bent substantially at a right angle from the axial direction to form an elbow portion.

[0007]

According to the pipe joint of the present invention, the one end portion provided with the flange and the other end portion on the opposite side are bent at substantially right angles from the axial direction of the pipe to form the elbow portion.
When the axial direction of the pipe to be connected such as the water supply pipe is orthogonal to the axial direction of the pipe joint, it is not necessary to connect with a separate elbow pipe, and the number of man-hours for piping work and the cost of parts can be reduced. . Further, since the elbow portion is integrated with the pipe joint, there is no risk of water leakage from the pipe joint itself.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a pipe joint according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a pipe joint, which is provided at one end of a main portion 2 of a pipe with a flange 3 whose flange surface is a surface orthogonal to the axial direction of the main portion 2 (see the alternate long and short dash line). ing. The flange 3 is provided with a mounting hole 4 for mounting on a wall surface or the like. An elbow portion 5 that is bent substantially at a right angle from the axial direction is integrally formed with the main portion 2 at an end portion on the side opposite to the flange 3. A female thread is formed on the inner peripheral surface of the flange 3 side and the inner peripheral surface of the elbow portion 5 with a predetermined length. The pipe joint 1 is entirely made of stainless steel in order to improve water resistance and chemical resistance.

With such a structure, when the water supply pipe 6 as the pipe to be connected has an axial direction orthogonal to the axial direction of the main portion 2, it is not necessary to make a connection by a separate elbow pipe. It is possible to reduce the man-hours of work and the cost of parts. Moreover, since the elbow portion 5 is integrated with the pipe joint 1, there is no risk of water leakage from the pipe joint 1 itself.

In this embodiment, a stainless steel product is shown, but the gist of the present invention is that the elbow portion is formed integrally with the pipe body by bending the pipe at a substantially right angle from the axial direction. Of course, other light alloys or vinyl chloride may be used. In addition, it is of course possible to change the thread form required for piping to a male thread or the like.

[0012]

As described above, according to the pipe joint of the present invention, the one end portion on which the flange is provided and the other end portion on the opposite side are formed substantially at right angles to the axial direction of the pipe. Since it is bent to form the elbow part, if the axial direction of the pipe to be connected such as the water supply pipe is orthogonal to the axial direction of the pipe joint, it is not necessary to connect with a separate elbow pipe and It is possible to reduce the cost of parts. Further, since the elbow portion is integrated with the pipe joint, there is no risk of water leakage from the pipe joint itself.
