Abstract

PURPOSE:To make solution through the solder-welding, when incapable of screwing in a pipe coupling itself, by forming an arcuate part at the center so as to permit the high jump over a pipe in crossing and by forming one end to a male-shaped part and the other to a female-shaped part. CONSTITUTION:As for the piping on the flat surface part of a floor, etc., an arcuate part 3 is formed at the center so as to jump (cross over) a crossing pipe 2, and one end is formed to a male-shaped part 4, and the other end is formed into a female-shaped part 5. Further, the pope 2 is fitted to the used purpose by forming both the end parts made of copper to a pipe coupling having a equal or different diameter. Accordingly, since the arcuate part 3 is formed at the center and is not formed into a screwin type, the necessity of turning the pipe coupling is obviated, and further, two kinds of pipes can be laid, keeping the regular equal interval. Accordingly, piping can be carried out, jumping the pipe which crosses in a reasonable manner in the equal interval, and the piping work can be facilitated through the solder welding.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to two types of pipes, such as water and hot water, water and water, which are arranged in parallel as much as possible, to be placed near indoor or outdoor walls or around foundations, especially on a flat surface such as a floor. In some cases, there is inevitably a situation where both pipes must intersect. The present invention relates to a jump type pipe joint that is used by jumping across pipes that intersect at such a time.

However, neither of the above-mentioned pipe fittings in the prior art has solved the problem when the piping systems intersect, and bypasses, elbows, nipples, elbows, nipples. , Elbow, nipple,
Due to the combination of elbows, the pipes are bent so as to straddle the intersecting pipes.
In kitchens, the distance between the tap of water and hot water is about 15 cm to 20 c
However, it becomes impossible to arrange them in parallel while maintaining this interval. If this is forcedly piped, there is a problem that a load is applied to the joint and water leakage occurs.

In addition, in the case of piping using a copper pipe, it has been a general rule that pipes are formed so as not to form a rising portion because air accumulation occurs. However, this hinders the piping work.

In view of these circumstances, the present invention forms an arcuate portion in the central portion so as to straddle intersecting pipes, and does not thread both ends, and the male and female fitting is performed to fit them. An object of the present invention is to provide a jump type pipe joint in which the connection is secured by soldering the parts.

In particular, since an arcuate portion is formed in the central portion so as to jump the intersecting pipes of the present invention, when both ends are screw holes, the intersecting pipes cause the pipe joint itself to be formed. In solving the problem of being unable to rotate and screw in by soldering, the pipe end was not threaded. In addition, in order to eliminate air accumulation, the top of the arc-shaped part formed in the center of the jump type pipe joint is dented to form a protruding part in the pipe and crush the air to create a large air mass. It was made not to be made.

[0007]

The present invention adopts the following technical means in order to solve the above problems. In the invention according to claim 1, in the case of piping on a flat portion such as a floor, an arcuate portion is formed in the center so that the intersecting pipes can be jumped, and one end is a male part and the other end is a female part. We adopted a technical means called a jump type pipe joint made of copper and having the same diameter at both ends.

According to the second aspect of the invention, in the case of piping on a flat surface such as a floor, an arcuate portion is formed in the center so that intersecting pipes can be jumped, one end is a male part and the other end is a female part. We adopted a technical means called a jump type pipe joint, which was made of copper and had different diameters at both ends.

According to the third aspect of the present invention, in the case of piping on a flat portion such as a floor, an arcuate portion is formed at the center so that the intersecting pipes can be jumped, and both ends are male portions. , We adopted a technical means called a jump type pipe joint in which both ends of the female part made of copper have the same diameter.

In a fourth aspect of the invention, in the case of piping on a flat portion such as a floor, an arcuate portion is formed in the center so that intersecting pipes can be jumped, and both ends are male portions or female portions. We adopted a technical means called a jump type pipe joint, which was made of copper and had different diameters at both ends.

According to the fifth aspect of the invention, in the case of piping on a flat portion such as a floor, an arcuate portion is formed in the center so that the intersecting pipes can be jumped, and the arcuate portion is parallel to the longitudinal direction of the arcuate portion. 2. The protrusion is formed on the inner wall of the pipe by denting the top portion into a substantially V-shaped vertical cross section.
The technical means of jump type pipe joint described in item 2, 3 or 4 was adopted.

[0012]

As a result of adopting the above technical means, the present invention forms an arcuate portion in the center so that the intersecting pipes can be jumped, and since it is not a screw type, it is not necessary to rotate the pipe joint, and Two types of pipes can be installed while maintaining regular intervals. Further, the top of the central arcuate portion is dented to form a protrusion in the pipe to eliminate the air trap.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. First, one example of a conventional technique will be described with reference to FIG. As described in the section of the problem to be solved by the above-mentioned invention, the elbow 6, the nipple 7, the elbow 6, the nipple 7, the elbow 6, the nipple 7, the elbow 6 and the four right-angle elbows, and the three nipples are U-shaped. Under the present circumstances, the pipes (floor rolling pipes) are arranged so that the intersecting pipes 2 can be jumped.

On the other hand, in the case of using the jump type pipe joint of the present invention, as can be understood from the one shown in FIG. A jump type pipe joint made of copper with an arcuate part 3 formed in the center so that it can jump (crossover), one end being a male part 4 and the other end being a female part 5, both ends having the same diameter.

In the case of piping on a flat surface such as a floor, an arcuate portion 3 is formed in the center so that the intersecting pipes 2 can be jumped, one end being a male part 4 and the other end being a female part 5. Jump type pipe joint made of copper with different diameters at both ends.

In the case of piping on a flat surface such as a floor, an arcuate portion 3 is formed in the center so that the intersecting pipes 2 can be jumped, and both ends are formed as male parts 4 or female parts 5. Jump type pipe joint made of copper and having the same diameter at both ends.

In the case of piping on a flat surface such as a floor, an arcuate portion 3 is formed at the center so that the intersecting pipes 2 can be jumped, and both ends are formed as male parts 4 or female parts 5. If each jump type pipe joint made of copper and having different diameters at both ends is adopted, it is possible to form pipes at regular intervals at regular intervals. Further, the jump type pipe joint does not need to be screwed in because a pipe to be welded is inserted into a male or female hole which can be soldered instead of a screw hole. Therefore, the disadvantage that the intersecting pipes 2 interfere and the pipe joint cannot rotate is eliminated.

Further, in the intersecting pipes 2 laid on a flat surface such as a floor, in the case of the present invention, air is introduced at the rising portion of the arc-shaped portion 3 for jumping which must be avoided in piping using a copper pipe. It accumulates and causes air accumulation. In order to eliminate this, as can be understood from those shown in FIGS. 3 and 4, the top of the arc-shaped portion 3 is parallel to the longitudinal direction of the jump type pipe joint in which the arc-shaped portion 3 is formed in the center. Is pressed and indented to form a protrusion 8 as an obstacle in the pipe, and the fluid collides with the protrusion 8 to crush the air and prevent air accumulation.

[0019]

As a result of adopting the above configuration, the present invention provides
The following effects can be obtained. (1) A pipe that intersects at equal intervals can be jumped without difficulty. (2) If they intersect with each other, if the screw-in type is used, the pipe joint cannot rotate, which makes the work very difficult. By solving this problem, the piping work was simplified by soldering. Therefore, the working time is shortened. (3) By forming a protrusion parallel to the longitudinal direction inside the jump type pipe joint having an arcuate portion at the center,
The air can collide with the projecting portion and be crushed so that air is not accumulated.
