の孔は溝７に複数個設けてもよい。 A connecting tube 2 is attached to the lower end of a flask-like instrument 1. A rubbing part 3 is formed at the lower part of the connecting pipe 2. A gas inlet 4 and a gas outlet 5 are formed to penetrate the wall of the connecting pipe 2 at a position above the rubbing portion 3 . Connecting pipe 2
A flow path 6 is formed concentrically with the connecting pipe 2 inside. The wall of the flow path 6 is integrated with the wall of the connecting pipe 2 at a position above the gas inlet 4 and the gas outlet 5. At least one groove 7 is provided on the outer peripheral surface of the rubbing portion 3 over the entire circumference. There are no particular restrictions on the width and depth of the groove 7, but usually the width is 0.5 to 5 mm and the depth is 0.1 to 5 mm.
It is 1mm. This groove is located on the outer circumferential surface of the rubbing part.
It is also possible to provide more than one book. At least one hole 8 is provided through the groove 7 . It is desirable that the diameter of the hole 8 is approximately equal to the width of the groove 7. A plurality of holes may be provided in the groove 7.

本考案の器具１は、第２図に示すように、擦り
合わせ部３の外形とほぼ一致する雌型の擦り合わ
せ部９を有する器具にはめこんで使用される。(Function) As shown in FIG. 2, the device 1 of the present invention is used by being fitted into a device having a female-shaped rubbing portion 9 that substantially matches the external shape of the rubbing portion 3.

に防止することができる。 An inert gas such as nitrogen gas or argon gas is supplied from the gas inlet 4 under slight pressure, for example 2 kg/
It is introduced under pressure of less than cm 2 and is discharged from the gas outlet 5. The introduced inert gas is supplied to the groove 7 via the hole 8. For this reason, the rubbing portion 3
Foreign matter such as air entering through the small gaps in the grooves 7 and 9 is blocked by the inert gas filling the grooves 7 and
You can't go deeper inside. Therefore, it is possible to effectively prevent foreign matter from being mixed into the fluid flowing through the flow path 6.
