Definitions
- the present invention relates to a connection structure of a resin pipe.
- Patent Document 1 Japanese Patent Laid-Open No. 9 126374 (see FIG. 5)
- an object of the present invention is to provide a connection structure of a resin pipe in which a fluid does not leak from between a metal noise and a resin pipe press-fitted into the metal noise for a long period of time.
- the resin pipe connection structure according to the present invention forms at least two enlarged diameter portions with a space in the end region of the metal pipe, and a seal groove in the circumferential groove with the enlarged diameter portions as a circumferential groove.
- a grease tube is press-fitted to a position exceeding the deepened diameter portion of the two enlarged diameter portions constituting the circumferential groove.
- a back ring may be accommodated together with the seal ring in the circumferential groove.
- the enlarged diameter portion of the metal pipe may be formed by a bulge carriage or a spool carriage.
- the insertion end of the resin tube that is press-fitted to the back side of the diameter-enlarged portion constituting the circumferential groove. You may provide an enlarged diameter part that will serve as a stagger.
- a diameter-enlarged portion may be provided on the back side of the diameter-enlarged portion constituting the circumferential groove to increase the strength against the removal of the resin pipe having a metal pipe force.
- the force fluid between the metal noise and the resin pipe press-fitted into the metal noise does not leak for a long period of time.
- FIG. 1 is a half sectional view of a structure for connecting a resin pipe to a metal pipe according to Embodiment 1 of the present invention.
- FIG. 2 is a cross-sectional view showing a state in which a seal ring and a back ring are fitted in a circumferential groove formed in the metal noise.
- FIG. 3 is a half sectional view of a connection structure of a resin pipe to a metal pipe similar to that in Example 1.
- FIG. 4 is a half sectional view of a structure for connecting a resin pipe to a metal pipe according to Embodiment 2 of the present invention.
- FIG. 5 is a half sectional view of a connection structure of a resin pipe to a metal pipe similar to that in Example 2.
- FIG. 1 is a semi-sectional view of a connection structure of a resin pipe 2 to a metal pipe 1 according to Embodiment 1 of the present invention.
- FIG. 2 shows a seal ring SR and a back in a circumferential groove 12 formed in the metal pipe 1. A cross-sectional view with the ring BR fitted is shown.
- this metal pipe 1 has two enlarged diameter portions 10 at a constant interval near the tip. 11 is formed (formed by bulging or spooling), and the portion between the enlarged diameter portions 10 and 11 is a circumferential groove 12 into which a seal ring SR (mainly O-ring) is fitted. As shown in FIG. 2, a back ring BR may be fitted into the circumferential groove 12 together with the seal ring SR.
- a seal ring SR mainly O-ring
- the enlarged diameter portion 10 is formed into a shape that gradually increases in diameter from the front end toward the back side and then rapidly decreases in diameter as shown in FIG. .
- the enlarged diameter portion 11 is formed into a shape that rapidly expands and then rapidly decreases in diameter as shown in Fig. 1.
- the outermost diameters of the enlarged diameter portions 10 and 11 are substantially the same, and the height thereof is set slightly smaller than the outer diameter of the seal ring SR.
- the resin pipe 2 has a single-layer or multi-layer structure made of, for example, nylon resin or a fluorine-based material, and is gradually pressed into the metal pipe 1 while being expanded in diameter. It is as an inner diameter. Therefore, when the resin tube 2 is press-fitted into the metal pipe 1, a pressure contact force acts between the metal Neuve 1 and the resin tube 2.
- the seal ring 12 is made of a fluorine-based material or the like.
- the metal pipe 1 is attached in such a manner that it is press-fitted into the hole 90 provided in the fixed wall 9 as shown in FIG. 3, and the resin pipe 2 is pressed into the metal pipe 1 portion protruding from the fixed wall 9. Speak as a person.
- the metal pipe 1 has enlarged diameter portions 10 and 11, and is the same as the enlarged diameter portion 11 with a certain distance behind the enlarged diameter portion 11.
- An enlarged diameter portion 13 having a shape is formed.
- the metal pipe 1 is press-fitted or loosely fitted into the hole 90 until the back side surface of the enlarged diameter portion 13 comes into contact with the outer surface of the fixed wall 9.
- the configuration of the resin tube 2 is the same as that described above.
- the press-fitting of the resin tube 2 into the metal pipe 1 is performed until the tip of the resin tube 2 comes into contact with the front side wall surface of the enlarged diameter portion 13.
- FIG. 4 shows a half cross-sectional view of the connection structure of the resin tube 2 to the metal pipe 1 according to Embodiment 2 of the present invention.
- the metal pipe 1 in the second embodiment has the enlarged diameter portions 10 and 11 of the first embodiment, and further increases the strength against the detachment of the resin pipe 2 from the metal pipe 1.
- an enlarged diameter part having a cross-sectional mountain shape (a shape that gradually increases in diameter toward the inner side and then gradually decreases in diameter) on the inner side. 14 is provided.
- the metal pipe 1 is replaced with an enlarged diameter portion 14 having a mountain-shaped cross section, and as shown in FIG. In this case as well, the strength against detachment of the resin tube 2 from the metal pipe 1 increases in the same manner.
- an enlarged diameter portion functioning as a stagger at the insertion end of the resin tube 2 can be formed on the back side of the enlarged diameter portions 14, 15.
