[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, when measuring the pressure or the like of a fluid pipe (a), a T-shaped pipe joint (b) is connected to the fluid pipe (a), and the T-shaped pipe joint is connected. A pressure gauge (e) or the like was connected to the female screw (d) of the branch pipe (c) of (b) by screw connection.

Alternatively, as shown in FIG. 6, a through hole (f) is formed in the fluid pipe (a), and a short pipe (g) with a connection portion is welded (h) to the through hole (h) to connect the fluid pipe (b). A not-shown pressure gauge or the like is connected to the connection section (i) with female threads of the short pipe (g).

Alternatively, as shown in FIG. 7, a short pipe with a screw hole (ル) is welded (ヲ) to one connecting portion of a T-shaped pipe joint (ヌ) to form a screw hole in the short pipe (ル). A pressure gauge (not shown) is connected to (W), and a pipe (not shown) is connected to another connection portion of the T-shaped pipe joint (N).

[0005]

However, regardless of the conventional T-shaped pipe joint (b), short pipe with connecting part (g), or short pipe with screw hole (lu), Only one device such as a pressure gauge can be connected. For example, when trying to connect various devices such as a thermometer and a sampling valve in addition to a pressure gauge, a plurality of T-shaped fittings (b) etc. It had to be provided, and the construction was troublesome and costly.

The present invention has been made in view of such problems in conventional pipe joints and the like, and has as its object to solve the above problems and connect a plurality of various devices. It is an object of the present invention to provide a pipe joint provided with a connection part to various devices that can perform the connection.

[0007]

In order to achieve the above object, a pipe joint having a connection portion with various devices according to the present invention can be connected to various devices such as a pressure gauge, a thermometer and a sampling valve. A pipe joint provided with a plurality of parts, wherein a plurality of connection parts with various devices are provided.

[0008] The material of the pipe joint of the present invention may be any of those conventionally used as the material of the pipe joint, and is not particularly limited.
Hard vinyl chloride resins, synthetic resins such as polyethylene and polypropylene, and metals such as ordinary steel, stainless steel, cast iron, aluminum, gunmetal and brass can be used.

[Operation] In the pipe joint according to the present invention having a connection portion with various devices, a plurality of connection portions with various devices are provided, so that a plurality of various devices can be connected. .

[0010]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an example of a pipe joint having a connection portion with various devices according to the present invention, and FIG. 2 is a cross-sectional view taken along line II-II in FIG.

In FIGS. 1 and 2, reference numeral 1 denotes a pipe joint provided with a connection portion to various devices, and connection portions 11, 11 for connection to piping are provided at both ends of the pipe joint 1. Numerals 12 and 12 denote connecting portions for connecting to two kinds of devices provided in a branched manner in a conduit between the connecting portions 11 and 11, and female screws 12 are provided in the connecting portions 12 and 12.
1 is provided.

In the pipe joint 1 shown in FIGS. 1 and 2, the connecting parts 12 and 12 for connecting two various devices are provided, so that in use, for example, a thermometer as well as a pressure gauge can be connected. .

FIGS. 3 and 4 are front views showing another example of a pipe joint provided with a connection portion to various devices according to the present invention, and FIG.
FIG. 4 is a sectional view taken along line IV-IV of FIG. In the pipe joint 1a shown in FIGS. 3 and 4, the pipes between the connecting parts 11a, 11a are vertically connected in a branching manner to the connecting parts 12a, 1
2a, 12a and an oblique connection portion 13 are provided, and each connection portion 12a, 13 is provided with a female screw 121a, 131. The oblique connection part 13 is opened on the slope 14.

In the pipe joint 1a shown in FIGS. 3 and 4, the pipes between the connecting portions 11a, 11a are vertically connected in a branching manner to the connecting portions 12a, 12a, 12a and three oblique connecting portions 13 with various devices. Are provided, so that in use, for example, four various devices such as a pressure gauge can be connected.

Although the embodiment of the present invention has been described with reference to the drawings, the configuration of the present invention is not limited to the illustrated embodiment, and a design change within the scope of the present invention may be made. Included in the range.

For example, instead of connecting parts for butt connection, such as connecting parts 11 and 11a for pipe joints 1 and 1a shown in the drawing, they may be used as receiving ports, flanges, and screw joints. May be used as a connection part.
