摘要： PROBLEM TO BE SOLVED: To reduce wearing of a heat insulating material in the periphery of a stud bolt hole caused by vibration so as to reduce the creation of gaps caused by falling or drooping of the heat insulating material by loading a pressing plate member composed of a belt-like seat plate part for pressing a divided heat insulating material and a shelf part for avoiding the displacement of the heat insulating material in the circumferential direction. SOLUTION: By pressing a divided heat insulating material 6 with a seat plate part 9a and preventing its displacement in the circumferential direction with a shelf part 9b, the expansion of the bolt hole of the divided heat insulating material caused by vibration or thermal expansion is prevented, falling of, among the divided heat insulating material portions, the divided heat insulating material portion in the side face part of a sleeve most easily affected by gravity or drooping of the divided heat insulating material from a stud bolt is reduced and the creation of gap between the heat insulating material portions or between the heat insulating material and a flange is reduced.

摘要： PURPOSE: To provide a flexible joint in which a deteriorating condition of a film body can be detected with the lapse of time. CONSTITUTION: A flexible joint is constructed by integrating a cloth type member 11, which is woven of carbon fiber thread 11a having conductivity in the expansion direction of the flexible joint and glass fiber thread 11b, with a film body 10, which is made of PTFE film, by means of thermal fusion. The flexible joint is connected to ducts 12 via flange parts 10a, 11c formed in both ends of the flexible joint. In this way, the cloth type member 11 functions as a reinforcing member for the flexible joint, while a deteriorating condition of the film body 10 can be detected with the lapse of time by measuring electric resistance generated when the fiber in the cloth type member is gradually cut off.

摘要： PURPOSE:To improve cushionability, compession recovery and stress resistance relaxing performance of a cord-shaped gland packing which is manufactured by braiding using a knitting yarn, formed of a flexible expansion graphite tape and a reinforcing knitting bag unit consisting of fiber material. CONSTITUTION:A flexible expansion graphite tape 1 is coated with a knitting bag unit 2 of metal wire by a bag knitting machine, and this graphite tape- contained knitting bag unit A1 is folded in a width direction by a folding machine, comprising a male piece 3 and a female piece 4, and formed into knitting yarn A2, to constitute a cord-shaped gland packing 5 by braiding using this knitting yarn A2. In this way, since the knitting yarn A2 is formed into a sandwich structure, by integrally connecting the graphite tape and the knitting bag unit 2 through folding action, and also rich in elasticity further into a uniform fine knitting yarn, a packing braided by this knitting yarn obtains an effect of increasing cushionability, compression recovery and further stress resistance relaxing performance or the like.

摘要： PURPOSE:To provide molded packing which utilizes a characteristic of flexible graphite to the fullest, and is good in storability to a stuffing box in addition to takeout workability by a packing tool after use, plus excellent in fittability and sealability under low clamping pressure. CONSTITUTION:A flexible graphitic tape 1 of more than 6mm in width and a knitted bag body 2 consisting of a fiber material covered on the tape 1 both are extended in the longitudinal direction, whereby this knitted bag body is gathered thin, and the graphitic tape is plastically deformed into curl form in the cross direction, while a strip material being made up of projecting the cross direction both edge partsto serration from stitches of the knitted bag body is set down to a molded blank, rolling this blank into a forming die, and compressed and molded into molded packing 7. Since flexibility, compressibility and shaft-fittability are all good enough and reinforced with the knitted bag body, stowability to a stuffing box and takeout workability by a packing tool after use are all also good enough.

摘要： PURPOSE:To improve the braiding performance, shaft seal performance, and safety by allowing the mixture consisting of hydrocarbon group polymer, siloxane group polymer, mineral oil, and minute graphite powder to exist in distribution in the gap of the fibers of carbon fiber bundles of a braided packing and between the surface and the fiber bundles. CONSTITUTION:Carbon fibers are S-twisted in 100T/m, and a 2-ply yarn is obtained by Z-twisting two pieces of S-twisted bodies in 100T/m. Said yarn is impregnated by 25-35% with the mixed impregnant consisting of graphite, hydrocarbon group compounds, siloxane group polymer having at least a viscos ity of 100,000 c.p., mineral oil, and solvent. Then, a braided article 1 is constitut ed by interlocking-braiding each yarn in 32 points with a gear ratio of upper 34 and lower 48, weight of 500g, and a die of 9.5 square by an ordinary knitting braiding machine. Said braided article 1 is impregnated by 20-30% with the impregnant consisting of four parts graphite, two parts hydrocarbon group polymer, siloxane group polymer, five parts mineral oil, and solvent. The, roller process is applied, and then the braided packing having a density of 1.0g/cm and a dimension of 9.5mm can be obtained.

摘要： PROBLEM TO BE SOLVED: To reduce breakage and detachment of heat insulating materials in a flexible joint apparatus for use at high temperature. SOLUTION: A flexible joint apparatus 1 is formed so that: flanges 3a, 3b which are fixed to duct sleeves 2a, 2b separated in their communication are connected to each other by cylindrical film bodies 4 capable of extending and contracting; and heat insulating materials 6 are inserted into stud bolts 5a, 5b stuck on the duct sleeves 2a, 2b. Lengths (f) of openings between the duct sleeves 2a, 2b are not less than 75% of the lengths (e) between the stud bolts 5a, 5b. Accordingly, a first layer of the heat insulating materials 6 can bend gently to prevent a second layer of the heat resistant materials 6 from being strongly pressed down.
