摘要： PURPOSE:To prevent the trouble in the revolution of a valve shaft due to the coagulation of hot wind in a chamber by connecting the chamber formed between the valve shaft and the flange of a casing to a drain discharge part through a passage formed onto the flange. CONSTITUTION:In a flow-rate control valve, a valve body 2 is rotatably arranged into a casing 3 on which a flow passage is formed from heat-resisting material. The chamber A formed between the valve shaft 22 of a valve body and the flanges 33 and 35 of a casing 3 is connected to a drain discharge part 6 through a passage formed onto the flange. Therefore, even if the hot wind containing solvents, carbon powder, etc. intrudes into the chamber A from the gap (g) formed between the valve shaft 22 and the heat-resisting members 36, 36a, 37 and 37a, said hot wind is discharged outside, passing through the valve 62 in the drain discharge part 6, and coagulation or the formation of rust in the chamber A is prevented.

摘要： PURPOSE:To correctly form a flow passage by inserting the first and the second heat-resisting members from the both sides of a valve piece arranged in a casing and fitting pressing members onto the both sides. CONSTITUTION:As for the outer cylinders 34 and 34a made of steel, the outside diameter is the cylindrical first heat-resisting member fitted onto the inside diameter of an outer cylinder 31, and the semicircular cut parts 35 and 35a into which a valve shaft 22 is inserted are formed in the upper part. The second heat-resisting members 36 and 36a in cylindrival from longer than the first heat-resisting members 34 and 34a are fitted onto the inside diameters of the first heat-resisting members 34 and 34a. The first and the second heat-resisting members are divided into two parts from the center to form symmetrical structure, and inserted onto the both sides of the valve piece 2 arranged at the center in the outer cylinder 31, and said valve piece is supported in rotatable ways. The pressing members 43 and 43a in symmetrical structure are fitted onto the outer peripheral part of the both heat-resisting members, and stop metal fittings 46 and 46a are fitted onto the outer peripheral parts of the pressing members, and welded onto the inside wall of the outer cylinder 31, and these members are integrally jointed and fixed.

摘要： PURPOSE:To correctly open and close a fluid passage by jointing a pair of supporting members made of ceramics which support the lower part of a valve body by a valve plate, the basic part of a valve shaft, and from the both sides of a supporting shaft. CONSTITUTION:The supporting members 41 and 41a made of ceramics are jointed from the both sides onto the valve shaft 22 and the supporting shaft 23 of a valve body 2 through bushes 42 and 42a, and accommodated into an outer cylinder 31, and the valve shaft 22 is projected upwardly. In this state, the second heat-resisting members 36 and 36a are inserted form the both sides, and the first heat-resisting members 34 and 34a are inserted from the both sides onto the outer periphery, and the both members are jointed integrally by the pressing members 43 and 43a and the stop metal fittings 45 and 45a. Since the valve body 2 is supported at two points, strength is increased, and a fluid passage can be correctly opened and closed, and the gap between the inside walls of the supporting members 41 and 41a and a valve plate 21 can be reduced markedly.

摘要： PROBLEM TO BE SOLVED: To secure excellent quality in cross section even in the cutting of a thick plate thickness of steel plate or the like. SOLUTION: A laser beam is irradiated on a stock to be cut and oxygen (O2 ) of an assist gas is fed to execute cutting while transferring a nozzle (laser beam condensing part 10) at a prescribed speed. When the nozzle reaches the once stopping position of cutting (B point), the laser beam is stopped (off) to irradiate with the speed of the nozzle (condensing part 10) maintained at the prescribed speed and the assist gas is continued to feed. The nozzle is stopped at a prescribed position C point after passing through B point and transferring by a prescribed distance as it is on the extension line of the locus of the cross section made by cutting. Since the irradiation of the laser beam is turned off at B point after the nozzle passes B point, the part succeeding to B point is not cut. The assist gas is stopped to feed at C point. Next, the nozzle is returned to B point and is again started cutting from B point changing the cutting condition.

摘要： PURPOSE:To repair easily, exactly and locally the inside wall of a blast furnace without requiring new installation of a manhole by inserting a repair device mounted with a spraying nozzle to a link mechanism to the inside of the furnace through the installed opening of the furnace wall and moving vertically and swiveling the nozzle. CONSTITUTION:A repair device is mounted on a lifter 14. A link mechanism 5 is retracted flat in this stage. The vertical position of the lifter 14 is so operated that a spraying nozzle 4 is brought approximately flush with the top edge of a nozzle opening 2 of a furnace wall cooling box. The lifter 14 is then moved to the furnace wall side where the nozzle 4 and supporting link 5 are inserted into the opening 2 and are forced to the prescribed position in the furnace. The link 5 is thereupon extended to set the height of the nozzle 4, i.e., the swiveling radius in the stage of swiveling for repair. A geared motor 11 is further rotated slightly to move the nozzle position in the case of directing the nozzle only to the limited local place. The spraying distance is made adequate and the spraying operation is started by opening a valve for force feeding repair material and pressurized water. The nozzle is swiveled by a motor 11.

摘要： PURPOSE:To repair the inside wall of a blast furnace while hot with a small number of operators without requiring new installation of a manhole by suspending freely vertically movably a sprayer with a swiveling nozzle to a travelling device supported to a wire rope provided between the opposed manholes in the upper part of the blast furnace. CONSTITUTION:A main wire rope 10 is extended between opposed manholes 2 in the upper part of a blast furnace. The operator pulls horizontally the wire rope by a hand winch on a working deck and attaches a travelling device 12 thereto. The operator ties further the sub-wire rope 13 of electrically driven winches 6, 7 to both sides of the device 12, moves the device 12 toward the right on the wire rope 10 and moves and stops the same until the swiveling axis of a spraying nozzle 18 aligns to the central axis of the furnace. The operator operates a lifting winch 15 to descend a sprayer 14 and stops the sprayer when the nozzle 18 arrives at the upper limit position of the wall required to be repaired. The length of the nozzle is so selected in this stage that the space between the nozzle tip and the inside wall 1 of the furnace attains a required value. A force feeder for the repair material to be sprayed and water and a device for swiveling the nozzle 18 is remotely operated to perform spraying at the uppermost level and thereafter the sprayer 14 is lowered and the same operation is repeated.
