Problems solved by technology

Therefore, it is difficult for ordinary operators to easily join the resin tubes.
[0005] In addition, due to long-term use, the above-mentioned mountain-shaped raised portion 105 will cause buckling deterioration over time, and as a result, there is a problem that the pipe material 104 is likely to fall out of the joint.

Embodiment 1

[0047] figure 2 A schematic sectional view showing the constitution of the resin pipe joint assembly according to the first embodiment of the present invention. The resin pipe joint assembly of this embodiment is as described above, and the specific configuration of the connection portion between the joint bodies 2 and 3 and the pipe assembly 6 will be described below.

[0048] The joint bodies 2, 3 are formed into a tubular structure having a flow channel 9, and sockets 7a, 7b are formed at one end thereof. The inner ring receiving portions 7 e , 7 f of the sockets 7 a , 7 b are parts for receiving the inner ring portions 6 b , 6 c of the pipe assembly 6 . The inner ring receiving portions 7e, 7f are formed by enlarging one end of the flow passage 9 of the socket 7a, 7b to have an inner diameter slightly larger than the outer diameter of the inner ring portions 6b, 6c. On the inner ring accommodating portions 7e, 7f, the depth (depth) thereof is set to be slightly shorter ...

Embodiment 2

[0056] image 3 A schematic cross-sectional view illustrating the configuration of a second embodiment of the resin pipe joint assembly according to the present invention is shown. The overall structure of the resin pipe joint assembly 1 of this embodiment is substantially the same as that of the resin pipe joint assembly 1 of the first embodiment described above, so in image 3 , the pair has the same characteristics as in Figure 1, figure 2 Structural elements with the same function are marked with the same symbols, and their detailed descriptions are omitted.

[0057] image 3 The embodiment shown in Figure 1, figure 2 The embodiment shown differs in that the tube portion 6a passes completely through the inner ring portion 21 and is integrally formed therewith. By employing this structure, the structure of the inner ring portion 21 before thermal bonding can be simplified.

[0058] On the other hand, the inner diameter of the inside of the joint body 22 is processed ...

Embodiment 3

[0063] Figure 4A schematic cross-sectional view showing the configuration of a third embodiment of the resin pipe joint assembly according to the present invention. The overall structure of the resin pipe joint assembly 1 of this embodiment is substantially the same as that of the resin pipe joint assembly 1 of the first embodiment described above, so in Figure 4 , the pair has the same characteristics as in Figure 1, figure 2 Structural elements with the same function are marked with the same symbols, and their detailed descriptions are omitted.

[0064] Figure 4 The embodiment shown in Figure 1, figure 2 The difference of the illustrated embodiment is that the inner ring part 31 is integrated with the inner side of the tube part 6a by thermal bonding, and as a result, the inner diameter of the flow channel 32 of the inner ring part 31 is the same as the inner diameter of the flow channel 12 of the tube part 6a. The inner diameter is different.

Abstract

A resin pipe joint is provided so that a general worker can easily connect a resin pipe without using a special tool. The resin pipe joint unit includes synthetic resin joint bodies, a synthetic resin pipe unit, and junk rings. The synthetic resin joint bodies have tubular sockets at one end portion thereof. The synthetic resin pipe unit has predetermined diameter and length, and inner ring portions are integrally formed in at least one end of a pipe portion in the synthetic resin pipe unit. The junk rings are screwed on the sockets of the joint bodies. In the resin pipe joint unit, the pipe unit is connected to the joint bodies by pressing end faces of the inner ring portions toward the side of the joint bodies respectively, when the junk rings are screwed on the sockets of the joint bodies.

Description

technical field [0001] The present invention relates to a resin pipe joint assembly used for piping of ultrapure water, chemical liquid, etc. used in manufacturing processes such as semiconductor manufacturing, pharmaceutical manufacturing, food processing, and chemical industry. Background technique [0002] As a conventional resin pipe joint, a joint disclosed in Japanese Patent No. 2949576 (page 3, FIG. 1 ) is known. The resin fittings such as Figure 5 shown. This resin pipe joint includes a joint body 100 , an inner ring 103 and a pressure roller 102 . The inner ring 103 is formed with a raised portion 105 having a mountain-shaped cross section and a cylindrical convex portion 107 . Then, the mountain-shaped raised portion 105 formed on the inner ring 103 is pressed into the one end portion 106 of the pipe material 104 , and this portion is inserted into the joint body 100 . Thus, by inserting the cylindrical protrusion 107 into the annular groove 108 , the pressing ...
