Abstract

PURPOSE:To provide a resin header enabling easy connection of connecting pipes different in diameter and in number. CONSTITUTION:The takeoff end connection 2 of a resin header with plural takeoff end connections 2 protrusively provided being opened in a longitudinal row at the side part of a body has end connections of different bores connected thereto. A large bore pipe end connection 21 is provided on the root side, and a small bore pipe end connection 22 is provided on the end part side. The end part inlet of the small bore pipe end connection 22 is sealed with a cover 5. At the time of connecting a pipe to the large bore pipe end connection 21, the small bore pipe end connection 22 is cut off to connect the pipe, and at the time of connecting a pipe to the small bore pipe end connection 22, the cover 5 is cut off to connect the pipe.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin header which is connected to a resin pipe by adhesion, fusion or the like.

[0002]

2. Description of the Related Art Conventionally, when a plurality of resin pipes having different diameters are connected to the outlet connection ports of the header, a plurality of resin pipes are connected in advance to the outlet connection ports opened in a plurality of columns. A plurality of resin pipes were taken out from the header and connected using a header in which the diameters were arranged according to the diameters of. That is, a header having the same diameter as the diameter of the taken-out resin pipe was required.

Further, when there is no take-out connection port corresponding to the diameter of the connecting resin pipe, a joint such as a different diameter socket which can be connected to each other is used for connection between the take-out connecting port of the header and the connecting pipe.

[0004]

The above-mentioned conventional header requires various headers having extraction connection ports corresponding to the diameter and number of pipes to be piped according to the construction site and construction conditions, and therefore many types of headers are required. Also, the work of connecting using joints was complicated. The present invention solves the above-mentioned problems and provides a resin header to which connecting pipes having different diameters can be easily connected.

[0005]

SUMMARY OF THE INVENTION The gist of the present invention is a resin header in which a plurality of lead-out connection ports are provided in a protruding manner in tandem on a side portion of a main body having a connection port on at least one end side. The take-out connection port has two connection ports having different diameters connected to each other, and has a connection port for a large-diameter pipe on the original side and a connection port for a small-diameter pipe on its end side, and the end of the connection port for a small-diameter pipe. The inlet is sealed with a lid. When connecting to the large diameter pipe connecting port, the small side pipe connecting port on the end side is cut off and connected, and when connecting to the small diameter pipe connecting port, the lid is cut off. It is a resin header characterized by being connected by.

[0006]

Since the present invention has the above-described structure, when connecting the small diameter pipe to the extraction connection port of the header, the lid of the end inlet can be removed to connect to the small diameter pipe connection port. When connecting to a large-diameter pipe, the connection port for a small-diameter pipe on the end portion side can be cut off to form a connection port for a large-diameter pipe. Therefore, connecting pipes having different diameters can be arbitrarily connected to the plurality of extraction connection ports.

Further, even if the number of connecting pipes is smaller than the number of connecting ports for taking out the header and there is a connecting port for which piping is not provided, there is no problem because the end portion of the connecting port has a lid. Furthermore, it is possible to easily cope with the case where an additional pipe is taken out after the piping work. Therefore, it is not necessary to care about the type of header when installing piping, and no extra joint is required. As a result, the construction period can be shortened and additional piping can be easily performed after the completion of piping work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a resin pipe header 1 showing an embodiment of the present invention. The main body 1 is provided with a connection port 2 at one end, and three side pipe connection ports 20 are provided on the side of the main body. The take-out connection port 20 is formed by connecting a large-diameter pipe connection port 21 on the base side and a small-diameter pipe connection port 22 on the end side thereof. In the figure, the heating wire 3 is provided on the inner peripheral surface of each of the connection ports 21, 22. Is buried. At the time of connection, the heating wire 3 is energized so as to be fused with the resin pipe 4 inserted in any one of the connection ports.

Further, a lid 5 is provided at the end of the small-diameter pipe connection port, and 6 and 7 are grooves provided to facilitate cutting. When connecting to the small diameter pipe 41, the lid 5 is inserted from the groove 7.
Is cut and connected to the connection port 22 for the small diameter pipe, and the large diameter pipe 4
When connecting with 2, it is cut from the groove 6 and connected to the connection port for large diameter pipe. Further, this connecting means may connect the connection port and the pipe by adhesion with an adhesive, or may use another fusion splicing joint 6 as shown in FIG. 2 to connect at the outer peripheral surface of the extraction connection port 20. .

[0010]

As described above, according to the header of the present invention, an outlet that matches the diameter of the connecting pipe can be arbitrarily obtained, which simplifies the pipe construction and eliminates the need to have many header types. The period is shortened. In addition, it is easy to add additional extraction pipes after the completion of piping work.
