(57) Abstract Objective The Simultaneous Peripheral Operation On-Line which forms the internal pairotsuto valve the Inlaying equipmentImprovement of endurance of the seal part between the holes is assured. Constitution In peripheral face of both destals of Simultaneous Peripheral Operation On-Line 17 installation channel 25 to be done husband Various lap facilities, on rim side of each installation channel 25, the guide cylinderThe inner skin of 7 it fits, being superior to the slidability of teflon resin and the likeWhen is the seal ring 26 which consists of the material is stuck Inlaying, thatOn inner circumference side of that seal ring 26, nitrile rubberAnd so on is superior in springiness the ring 27 for batsukuatsupu which Inlaying arrivalThe re te it is. Depending on the thing Simultaneous Peripheral Operation On-Line 17 sleeve frequentlySeal ring 26 wears the amount where the ring for batsukuatsupuBeing supplied by bullet enlarging power of 27, Simultaneous Peripheral Operation On-Line 17 and guide cylinder 7Seal Characteristic between the wa is connection is guaranteed in long term.
