材は容易にパイプ要素から取り外される。The present invention discloses a swivel fitting and a fitting assembly that can be used as a fitting. This reduces the number of seal leak paths in the entire piping system, reduces the number of deformations of the required pipe elements, increases the effectiveness of the individual pipe elements and reduces the price of the required pipe elements. Each of the pair of pipe retaining members has a lumen for receiving one of the pair of pipe elements. A pair of retaining members are attached to their respective pipe elements via a mounting material such as a mounting ring. The ends of the two pipe elements are abutted by the two holding members being screwed together by pipes and drawn together.
That is, the two holding members are screwed together while maintaining the two pipe elements at a predetermined distance from the two holding members. Then, by rotating one holding member with respect to the other, both pipe elements are pressed so that their ends are pressed against each other. The retaining member can be easily removed from the pipe element by removing the mounting member.

さい。Each pipe element has a central bore extending along its length, and each element has a recess adjacent the central bore. The first element of the pipe element includes a substantially smooth inner surface that defines the outer boundary of the recess. When joining pipe elements, a torus seal is fitted in the two recesses,
The seal extends along a portion of the length of the two pipes adjacent each end of the pipe element. That is, the seal extends across the seam of the pipe elements to prevent leakage at the joint between the pipe elements. The toroidal seal includes an outer portion having a plurality of streaks which press against the smooth inner surface of the recess of the first pipe element. The seal is pushed into the smooth recess, causing the streak of the seal to press against the surface of the first pipe element so that when separating the two pipe elements, the seal remains in the recess,
This prevents the seal from falling off or being lost. The outer diameter of the torus seal and its streaks is slightly larger than the diameter of the smooth recess so that the outer portion of the streak is pressed tightly against the inner surface defining the outer boundary of the recess. When a pair of threaded nuts are used as the retaining members, the pipe elements to be joined can be of the same shape, thereby reducing the number of profile elements to be manufactured. The cross-sectional shape of the pipe element of the present invention is small compared to unions and similar devices in conventional fittings.

Is fed to fix the member (12) to the pipe element (10), and the stopper (19) is put back into the hole cavity (20). The stopper (24) is removed from the hole cavity (25), and the plurality of mounting materials (17) are fed into the grooves (18c, 18d) through the hole cavity (25) to move the member (13) to the pipe element (11). Fix it. Stopper (2
4) is returned into the hole cavity (25) and the mounting material (17) is kept in place. A seal member is placed in a portion of the recess (30) adjacent to the central hole cavity (31) of the pipe element (10). The pipe element (10, 11) is arranged by aligning the central hole cavity (31) of the pipe element (10) with the central hole cavity (32) of the pipe element (11).
The member (12) is rotated with respect to the member (13), and the member (1
The threaded portion (12b) of 2) meshes with the threaded portion (13b) of the member (13) to draw the pipe elements (10, 11) toward the position shown in FIG. A portion of the seal member (26) enters the recess (36) adjacent the central bore (32) to provide a fluid tight seal between the elements (10, 11). Since the groove (18c) is formed wider than the groove (18d), the tip ends of the screws of the holding members (12, 13) can be screwed to each other first. After thus partially engaging both holding members with each other, one holding member (12)
Is rotated with respect to the other holding member (13) to bring the pipe elements (10, 11) into contact with each other to make them water resistant.

When it is desired to separate the pipe element (11) from the member (12d)
Is rotated with respect to the member (13) to separate the members (12d, 13) as shown in FIG. When the member (12d) is further rotated with respect to the member (13), the shoulder (37) of the groove (18e) is pressed against the mounting material (17a), and the shoulder (38) of the groove (18c) is mounted on the mounting material (17b). Then, the pipe element (10) is moved away from the pipe element (11) as shown in FIG. With a slight separation of the elements (10,11), the threaded parts (12b, 13b)
The pressure within the bore (31, 32) is released while the elements are still in engagement, preventing the elements (10, 11) from jumping apart. When the holding member (12d) is further rotated, the pipe elements (10, 11) are separated as shown in FIG.
部材（12,13）の回転によるパイプ要素（10,11）の強制
分離は要素（10,11）が固着し合うことを防ぎ、パイプ
ライン系統のシール交換又は解装を便にする。The forced separation of the pipe elements (10,11) by the rotation of the members (12,13) prevents the elements (10,11) from sticking together and makes the replacement or disassembly of the pipeline system convenient.

再連結する。The improved seal (26a) used in the joint device (9, 9a) is the seventh
It is disclosed in an enlarged view of the figure. The streaked outer portion (26b) of the seal (26a) is pressed against the substantially smooth inner surface of the recess (30) to seal the seal (26a) when separating the pipe elements (10,11). Fix to (10).
This eliminates the risk of the seal (26a) falling off and being lost when the holding members (12d, 13) are separated. When the pipe elements (10, 11) are clamped as shown in FIG. 3, the right-hand part of the seal (26a) (FIG. 3, FIG. 7) is placed in the recess (30) and the seal ( The left-hand part of 26a) is placed in the recess (36). Since the mounting material (17) is clamped in the grooves (18a to 18d), there are no parts to be separated when the members (12, 13) are separated. When the seal (26a) needs to be replaced, the member (12d) is rotated relative to the member (13) until the members (12d, 13) separate. The part with the streak (26b) has the surface of the depression (30) (30
Insert the seal (26a) into the central hole cavity (31) until it comes off from b).
To pull in the axial direction. Push the new seal (26a) into the recess (30) and insert the holding member (12d) into the holding member (1
Rotate against 3) to reconnect the pipe element to the fluid tight position.

b）からはがすことが多少ながら難しい。Since a plurality of lines (40) (Fig. 8) are formed on the seal (26a), they are inclined toward the central groove (41) and the lines (40) are formed on the surface (30b) of the recess (30). ), Helping seal (26a) move into recess (30) (FIG. 7). Seal (26a) is hollow (3
When tilting from right to left in 0), this tilt causes the radial outer tips to be pressed more firmly against the surface. The diameter D1 of the seal (26a) is slightly smaller than the diameter D2 of the recess (30) (.001-.005 ″, 0.02
5 ~ 0.127mm) Large, with a seal (26
a) be tightly fitted. The lines (40) can be helical screws of the type used for bolts, or they can be concentrically formed. The advantages of spiral screws are
It can be formed using conventional thread cutting dies of the type used for large bolts. The threading die is also
The outer tip (42) of the seal (26a) can be inexpensively and accurately made to have a predetermined diameter value. The advantage of a seal with concentric stripes is the removal of the seal:
The replacement is easier than the spiral screw. When the seal is pulled for disengagement, the concentric, lined seal is approximately toward the central axis of the recess (30). On the other hand, in the case of a spiral screw, it may receive resistance away from the central axis of the depression (30), and the surface of the depression (30) (36
It is a little difficult to remove from b).

A streak seal is attached to one of the pipe elements to prevent the seal from falling out when separating the pair of pipe elements. The other element is also attached to this pipe element so that the loose parts do not fall out or get lost.
