置。[Claims for Utility Model Registration] 1. Gas-permeable and corrosion-resistant porous tube 5
is placed in a vacuum chamber 9, and a degassing device is configured to degas dissolved gas in a liquid flowing through the porous tube 5, in which a connecting portion is provided on both the inlet side and the outlet side of the porous tube 5. A deaerator characterized in that the degassing device is integrally penetrated through the vacuum chamber 9 and taken out to the outside, and the penetrating portion 10 is hermetically sealed by a sealing tool 11. 2. The sealing device 11 includes a cylindrical sealing device main body 19 having an insertion hole 22 for inserting the porous tube 5, and a porous tube 5 inserted into the inner wall surface at the axial end of the sealing device main body 19. The sealing tool main body 19 includes an elastically deformable sealing body 20 that is fitted into a sealing part 23 provided between the outer peripheral surfaces of 2. The degassing device according to claim 1, wherein the degassing device is inserted into the through-hole 10 of the vacuum chamber 9 and hermetically sealed. 3. The sealing body 20 is composed of a cylindrical piece with thin walls at both ends in the axial direction, and when the sealing body 20 is fitted into the sealing part 23 by the pressing member 21, both ends are elastically deformed in the radial direction. Item 2 Deaerator.
