[Embodiment of device]

 Embodiments of the present invention will be described with reference to the accompanying drawings. The pipe distributor of the present invention is a distributor that is installed in a branch portion of a main pipe for water supply and a branch pipe, and as shown in FIG. 1, at least one main body member ( A body (1) consisting of a unit body), and a connecting portion (2) with a main pipe provided at the center of one body member constituting the body (1) or at one end of the body (1), It is mainly composed of an end cap (3) attached to the open end of the body (1) not connected to the main pipe. The end cap (3) has an air discharge port (4) for discharging the air inside the body (1), and the main body member forming the body (1) has at least one branch pipe. It is equipped with a tubular connection (spigot) (5).

The body (1) illustrated in FIG. 1 is configured by connecting five main body members in order to set the connection port (5) to 10. As shown in FIG. 2, the main body member, which is a structural unit of the body (1), has a body portion made of a pipe having a diameter similar to that of a main pipe (not shown) for water supply, and, for example, two connection members. Consists of mouth (5). The body part of the body member has one end (the left end in Fig. 2) formed thin so that the outer diameter is small and the other end (Fig. The right end of 2) is formed thin and has a large inner diameter. That is, the two body members can be replenished by inserting one end into the other end.

The number of the connection ports (5) of the above-mentioned main body member can be appropriately set according to the purpose of use. Therefore, for example, in the case of manufacturing a distributor having six connection ports (5), three body members having two connection ports (5) are connected or three connection ports (5) are connected. It suffices to connect two main body members having a mouth. That is, in the body (1), the number of connection ports (5) protruding from the body is set to a desired number, for example, 1 to 5 by adjusting the number of connected main body members as necessary. You can

The connection part (2) with the main pipe is an inlet (inlet) for introducing the water of the main pipe into the body (1), and usually, in a main body member constituting the body (1), for example, It is provided at the central portion of one main body member located at the center or at one end portion of the main body member located at one end of the body (1) as shown in FIG. The connection part (2) at the end of the body (1) illustrated in FIG. 1 is composed of parts such as a grab ring, an O-ring, and a space washer so that it can be liquid-tightly connected to the main pipe. Has been done.

The end cap (3) is, for example, formed into a shape in which a ball is roughly cut in half, and is configured such that its edge is fitted into the open end of the body (1), and the open end is sealed. To do. Such an end cap (3) is provided at both ends of the body (1) when the connecting portion (2) with the main pipe is provided in the central portion of the main body member, and also at the connecting portion with the main pipe ( When 2) is provided at one end of the body (1), it is attached to the other end of the body (1). The air outlet (4) attached to the end cap (3) has its lid normally oriented upward as shown in the figure, so that the air inside can be exhausted if necessary. .

In the pipe distributor of the present invention, the end cap (3) including the body (1) and the air discharge port (4) is respectively light weight, durability, corrosion resistance and heat retention. It is formed by injection molding a thermoplastic resin. In particular, it is preferable that the main body member forming the body (1) is integrally formed with the connection port (5) with a thermoplastic resin.

Examples of the thermoplastic resin include polyolefin resins such as polyethylene, polypropylene and polybutylene, polyolefin copolymer resins, polystyrene resins, acrylonitrile-styrene resins, acrylonitrile-styrene-butadiene resins and polyvinyl chloride resins. The polybutylene resin is particularly preferable.

In the construction of the pipe distributor of the present invention, first, an appropriate number of main body members are inserted and connected according to the number of connection ports (5) required, and the respective connecting portions are fused to form a body. Assemble (1). Then, the end cap (3) is attached if necessary. Next, after connecting the end portion of the main pipe, which is arranged in advance, to the connection portion (2), the branch pipe is connected to the connection port (5). To connect the branch pipe, insert the connecting end of the branch pipe fitted with a rubber ring as it is, or use an appropriate fusing pipe joint and heat the connecting end of the branch pipe. Workability can be further improved by wearing and connecting.

As described above, since the body (1) has a connection structure in which main body members injection-molded with a thermoplastic resin are inserted into each other and fused, the pipe distributor according to the present invention is It is lightweight, convenient to handle, and has excellent durability, corrosion resistance, and heat retention. Furthermore, there is almost no contraction or expansion due to temperature changes, and synthetic resin piping can be connected smoothly. Moreover, since the tubular connection port (5) provided in the body (1) is used for the connection of the branch pipe, the construction can be performed easily and safely. Moreover, the cost can be reduced due to the material composition and the manufacturing method. It should be noted that the present invention is not limited to the above-described embodiment, and can be implemented in various forms without departing from the gist thereof.
