Include the tool bit, hold handle and measuring mechanism, have the blade in the tool bit, be equipped with the wing bolt on the tool bit, this wing bolt runs through the tool bit locks the blade, hold the micrometric screw who has spring and measuring mechanism in the handle, the micrometric screw front end is equipped with the copper cap, the measuring mechanism includes the fixed sleeving, and the fixed sleeving is connected with the microdrum, and the fixed sleeving is fixed on holding the handle through locking screw. The utility model is suitable for a height measurement of any traditional vapor seal, the adjustment that is applicable to any traditional vapor seal is simultaneously repaiied and is scraped, and the suitability is stronger, and it is more convenient to use, repaiies that to scrape the precision higher, once repaiies to scrape just can meet the demands completely.
Description
Technical field
The utility model relates to a kind of adjustment and repaiies the instrument scraping turbine steam seal, is specifically related to a kind of packing and quantitatively repaiies curette.
Background technology
Steam turbine is the power core parts of whole power plant, and the collision between the dynamic and static parts of steam turbine, must leave suitable gap.The existence in these gaps certainly leads to again leakage vapour makes efficiency reduce, in order to solve this contradiction, and the gap location mounting sealing device between steam turbine sound parts, i.e. packing.Because before and after cylinder internal, dividing plate and the moving vane both sides of band degree of reaction also exist pressure reduction, and must keep certain gap between corresponding each dynamic and static part, this has just caused certain steam to spill or air bleeds in cylinder.In order to reduce leakage, just in these corresponding positions, packing is installed.
The effect of packing is exactly reduce leakage, and therefore labyrinth clearance is the smaller the better, and cause security incident to there is not sound friction, ensure that labyrinth clearance is enough large again, in order to solve this contradiction, gap regudation of steam sealing is to just right most important.The adjustment of labyrinth clearance in the past adopts the instrument such as slide measure or depth gauge rule to measure, because measuring surface is less or shakiness held up by survey tool, measurement data is not accurate enough, very large on the adjustment impact of labyrinth clearance, the survey tool that therefore on-the-spot needs are more accurately more accurate.Packing repair the scene of scraping generally adopt file, scraper even electric tool carry out repairing scraping, because the difference of gimmick or qualification, often cause gap regudation of steam sealing again and again or gap regudation of steam sealing is excessive exceeds standard, gap regudation of steam sealing is extremely wasted time and energy, it is on-the-spot that in the urgent need to one, everybody can operate, and the instrument that accuracy is high.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of packing quantitatively to repair curette, integrates and measures and repair the specific purpose tool scraping packing.
For achieving the above object, the technical solution adopted in the utility model is: packing quantitatively repaiies curette, and comprise cutter head, hold handle and measuring mechanism, have blade in cutter head, described cutter head is provided with wing bolt, and this wing bolt runs through cutter head by insert retention; Describedly hold in handle the micrometric screw having spring and measuring mechanism; Copper cap is equipped with in micrometric screw front end; Described measuring mechanism comprises fixed sleeving, and fixed sleeving is connected with microdrum, and fixed sleeving is fixed on by lock-screw and holds on handle.
Described blade front end is triangular in shape.
Described blade rear end is provided with jump ring.
Described measuring mechanism also comprises device for measuring force, and device for measuring force is connected with microdrum.
The beneficial effects of the utility model are: the utility model is applicable to the elevation carrection of any traditional packing, and the adjustment being simultaneously applicable to any traditional packing is repaiied and scraped, and applicability is stronger, uses more convenient, repair that to scrape precision higher, once repair to scrape just can meet the demands completely.

Reference numeral: 1 blade, 2 cutter heads, 3 wing bolts, 4 hold handle, 5 lock-screws, 6 fixed sleevings, 7 microdrums, 8 device for measuring force, 9 springs, 10 jump rings, 11 bronze medal caps, 12 micrometric screws, 13 measuring mechanisms.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, packing quantitatively repaiies curette, and comprise cutter head A2, hold handle 4 and measuring mechanism 13, have blade A1 in cutter head A2, blade A1 front end is triangular in shape, can not rotate; Just scrape, counter scrape can, there is no directionality, not by the restriction of packing size and position, without potential safety hazard.Described cutter head A2 is provided with wing bolt 3, and this wing bolt 3 runs through cutter head A2 locks blade A1; Describedly hold the micrometric screw 12 having spring 9 and measuring mechanism 13 in handle 4; Copper cap 11 is equipped with in micrometric screw 12 front end; protection micrometric screw 12; blade A1 rear end is provided with jump ring 10; for limit spring 9; measuring mechanism 13 comprises fixed sleeving 6, and fixed sleeving 6 is connected with microdrum 7, and fixed sleeving 6 is fixed on by lock-screw 5 to be held on handle 4; measuring mechanism 13 also comprises device for measuring force 8, and device for measuring force 8 is connected with microdrum 7.
Packing is quantitatively repaiied curette and is used as survey tool: adopt platform, by platform, clean out between packing and gland sealing gear, unclamp wing bolt 3 and lock-screw 5, the microdrum 7 that turns clockwise makes blade A1 move forward, left hand is pushed down and is held handle, the right hand slowly rotates thorn wheel, reading is checked after blade A1 is contacted with the working face of platform, then microdrum 7 is rotated counterclockwise, blade A1 is made to be retracted in cutter head A2, then cutter head A2 is ridden on gland sealing gear, turn clockwise microdrum 7, blade A1 is contacted with gland sealing gear, screw lock-screw 5, then reading is read, the difference of two numbers is exactly the discrepancy in elevation of gland sealing gear.
For increasing applicability widely, blade B1 and cutter head B2 has Multiple Type for changing, as shown in Figure 4, Figure 5, blade use blunt can reconditioning be sharp reuses.
Repair when scraping packing; first measure the height of gland sealing gear; unclamp lock-screw 5; then turn clockwise microdrum 7; rotate blade 1 simultaneously can move forward, adjustment amount is sealing tooth scraping amount, fastening wing bolt 3; for preventing damaging differential calculus ruler; be rotated counterclockwise microdrum 7, rotate more than 5mm, microdrum is separated with blade; protection microdrum; hold and hold handle 4 after band gloves, carry out returning something for repairs scraping facing to gland sealing gear with blade 1, till blade 1 is repaiied and can't be scraped gland sealing gear; repetition measurement gland sealing gear height, now repaiies the amount of scraping and just meets the demands.
