Abstract
The utility model discloses a steam turbine main steam valve eccentric measure, relating to an instrument measuring the eccentric hole of the main steam valve of a steam turbine. The utility model solves the problem of the low size precision of an eccentric pin connecting with the main steam valve and a bracket. The lower end of a measuring cylinder (7) is connected with a measuring block (12); the lower end of the first screw stem (8) is arranged within the measuring block (12); the upper terminal of the first screw stem (8) is connected with the lower end of the first joint (3); the upper end of the first joint (3) is connected with the first extension bar (1) through the first shaft housing (2); the second shaft housing (5) is arranged at the upper part of the first screw stem (8); a cylinder pin (4) is arranged on the second shaft housing (5); an insequent measuring block (11) is arranged within the measuring cylinder (7) on the upper part of the measuring block (12); the inclined plane of the insequent measuring block (11) is contacted with the second screw stem (10); the lower end of the second screw stem (10) passes a textile board (6) and is arranged within the measuring cylinder (7); the upper end of the second screw stem (10) is connected with the second extension pole (9) through a second joint (15) and a third shaft housing (14). The utility model is simple and practical and can reach a precision within plus or minus 0.05 when eccentric hole is measured.
Description
Technical field
The utility model relates to a kind of instrument of measuring eccentric orfice.
Background technology
The stop valve assembly is one of most critical, most important parts in the modern steam turbine, to the safe operation of steam turbine, plays a part last pipe protection defence line.That is to say, play the effect of urgent blocking-up admission when needed, and when steam turbine starts, control the rotating speed of steam turbine.Stop valve is fixed on the support by eccentric pin, and the cooperation of eccentric pin is directly connected to the security of stop valve operation.Be connected for eccentric pin between stop valve and support.The eccentric pin size is to measure in two parts assembling back to provide.Its dimensional accuracy is difficult to reach ± 0.05 with interior requirement.
The utility model content
The purpose of this utility model is the not high problem of eccentric pin dimensional accuracy that connects stop valve and support for solving, and provides a kind of Steam Turbine's Main Vaper Valve eccentric measurer.
The utility model is by first extension bar 1, first axle sleeve 2, first joint 3, straight pin 4, second axle sleeve 5, pressing plate 6, measure cylinder 7, first screw rod 8, second extension bar 9, second screw rod 10, oblique survey piece 11, survey piece 12, screw 13, the 3rd axle sleeve 14 and second joint 15 are formed, pressing plate 6 is connected with the upper end of measuring cylinder 7 by screw 13, the lower end of measuring cylinder 7 is connected with survey piece 12, pressing plate 6 is passed in the upper end of first screw rod 8, the lower end of first screw rod 8 is contained in to be surveyed in the piece 12, the upper end of first screw rod 8 is connected with the lower end of first joint 3, the upper end of first joint 3 is connected with first extension bar 1 by first axle sleeve 2, second axle sleeve 5 is equipped with on the top of first screw rod 8, on second axle sleeve 5 straight pin 4 is housed, oblique survey piece 11 is contained in the measurement cylinder 7 of surveying piece 12 tops, the inclined-plane of oblique survey piece 11 contacts with second screw rod 10, the lower end of second screw rod 10 is passed pressing plate 6 and is contained in the measurement cylinder 7, and the upper end of second screw rod 10 is connected with second extension bar 9 with the 3rd axle sleeve 14 by second joint 15.
The utlity model has following beneficial effect: be connected with eccentric pin between stop valve and support, the eccentric pin size is to provide at stop valve and support assembling back measurement, its dimensional accuracy reached ± 0.05 in, precision is higher, adopt the utility model can measure eccentric pin two distance of center circle from, and then the size of definite eccentric pin, simple and practical.
