（産業上の利用分野）
本発明は、流体の入っている容器内（外）から容器外（

るためのシール継手に関する。[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a method for transferring fluid from the inside (outside) of a container containing a fluid to the outside (outside) of the container.
This invention relates to a sealing joint for leading out (in) a cable to (inside) without leaking fluid.

る。(Prior technology) Connect the cable from inside (outside) the container containing the fluid to outside the container (
Various methods have been used to introduce (in) the fluid into the interior.One of the methods is to use a seal joint having a structure as shown in FIGS. 3 and 4.

て、容器内側Ｂ（外側Ｃ）から容器外側Ｃ（内側Ｂ）へ
導出（入）される。In this method, first, from the inside B (outside C) of the container to the outside C of the container.
The cable 4 is led out (into the inside B) through the main body 5 of the seal joint, and the washer 6, sealing material 1, and presser metal fitting 2 are assembled into the main body 5 with the cable 4 passed through,
When the cap nut 3 with the cable 4 passed through the cable passage hole 8 is engaged with the male screw 5-1 cut on the outside of the main body 5 and tightened, the end A of the presser metal fitting 2 and the inside of the cap nut 3 are connected. Contact. As the cap nut 3 is roughly tightened, the presser metal fitting 2 will crush the sealing material 1 between it and the washer metal fitting 6. When the cap nut is finally tightened to the specified torque value, the cable 4 will be sealed. , is led out (entered) from the container inside B (outside C) to the container outside C (inside B).

によって押え金具２の回転を止めることとする。Now, here, a moment is applied to the holding fitting 2 at the end A due to the friction between the cap nut 3 and the holding fitting 2 as the cap nut 3 rotates, and a shearing force is applied to the cable 4 at the boundary between the holding fitting 2 and the sealing material 1. , and in some cases may even break. To avoid this, key 7
The rotation of the presser metal fitting 2 is stopped by.

まうことかあった。However, depending on the type of sealing material 1, the tightening torque of the cap nut 3 may be quite large.
A large shearing force will be applied to the key 7 and the keyway. At this time, if the key 7 or the keyway is damaged during the first use due to multiple uses, the presser metal fitting 2 may be rotated due to an incomplete rotation stop, and the presser metal fitting 2 may be rotated as described above.
The cable 4 could be damaged by shearing at the boundary between the sealing material 1 and the sealing material 1.

る。(Problems to be Solved by the Invention) The present invention suppresses the sealing material without applying a moment to the holding fitting when tightening the cap bolt so that shearing force is not applied to the cable at the boundary between the holding fitting and the sealing material. The purpose is to provide a sealing joint that can be used.

Furthermore, the cable passes through a slit cut into the fi66 that engages with the cap nut 660 of the main body, and is inserted into the container (
It is characterized by being derived (in) from (outside).

挿通するケーブルに剪断力が働かない。(Function) Since the top of the push rod that presses the sealing material makes point contact with the rotation center of the inner surface of the cap nut, the rotation of the cap nut is not transmitted to the sealing material, the sealing material does not rotate, and the cable that passes through the inside of the sealing material. No shearing force is applied to the

いる。It is led out (into) the outside (inside) of the main body 11 from 1l-1b. The presser metal fitting 10 is held down as the cap nut 9 is tightened via a push rod 12 that makes dot point contact (section D) at the rotation center of the inner surface of the cap nut 9, which is a cap nut, and the sealing material 1 is crushed between it and the washer 6. The cap nut 9 is finally tightened to a specified torque and the cable 4 is sealed.
ここで、押し俸４とキャップナツト９の内面とは、上述
の如くキャップナツト９のほぼ回転中心で接触している
ため、キャップナツト９の回転によっても押し棒４には
ほとんどモーメントがかからず、よって押え金具１０も
ねじられることなくシール材を圧迫することができる。Here, since the push rod 4 and the inner surface of the cap nut 9 are in contact almost at the center of rotation of the cap nut 9 as described above, almost no moment is applied to the push rod 4 even when the cap nut 9 rotates. Therefore, the presser metal fitting 10 can also press the sealing material without being twisted.
なお、押し棒４と押え金具１０は組立て上の都合等によ
って予め接合あるいは一体成型しておいても全く同等な
効果が得られる。It should be noted that the same effect can be obtained even if the push rod 4 and the presser metal fitting 10 are joined or integrally molded in advance for convenience of assembly.
