継手部分における漏洩流体拡散防止構造。 The valve side flange and the pipe side flange, whose outer end surfaces abut each other via the flange sealing member, are fastened with a flange bolt without a head and a cap nut screwed onto both ends thereof, and each cap nut is tightened. and a radially divided seal retaining ring having a first seal member sandwiched between the opposing surfaces of the flange and the flange, and having a seal retaining portion and an engaging protrusion protrudingly formed on the inner circumferential portion;
While the engaging protrusion is engaged with the inner end surface of the valve side flange to prevent axial movement toward the tube side flange, and the axial end is closed by the seal holding section between the outer peripheral surfaces of both flanges. With the annular space formed, the second seal member was fitted and held on the outer periphery of both flanges, and the second seal member loaded into the annular space was positioned on the fluid transport pipe side and tightenably fastened to the seal holding ring. A leakage fluid diffusion prevention structure at a flange joint portion between a valve and fluid transport, characterized in that a radially divided seal pressing ring is pressed in the direction of the seal holding portion.
