Detailed description of the invention
Fig. 1, Fig. 2, in embodiment shown in Fig. 3, a kind of prosthetic device for repairing control valve stand base, including stationary positioned structure, rotary shaft 21, repair cutter 40, motor 30 and speed change gear 20, rotary shaft 21 one end activity connects after passing stationary positioned structure reparation cutter 40, the rotary shaft other end is fixedly connected in the speed change rotary shaft of speed change gear 20, it is fixedly connected on regulation valve body to be repaired with the stationary positioned structure place end face repairing cutter, repair the blade of cutter towards control valve stand base to be repaired, together with stationary positioned structure other end is fixedly connected with speed change gear, motor is together with speed change gear drive connection.Stationary positioned structure includes stationary positioned pedestal 10 and adpting flange 11, and stationary positioned pedestal 10 is fixed together with speed change gear 20, and adpting flange 11 is fixedly connected on stationary positioned pedestal, and regulation valve body to be repaired is fixedly connected on adpting flange 11.Repairing cutter 40 and include that cutting edge 41, cutting edge fix seat 42 and fixing bolt, cutting edge is fixed seat 42 and is fixedly connected in rotary shaft 21, and cutting edge 41 is fixedly connected on cutting edge by fixing bolt and fixes seat 42 front end.Fixing bolt includes that cutting edge fixes bolt 43 and cutting edge is fixed seat and fixed bolt 44, cutting edge is fixed bolt 43 and cutting edge is fixedly connected on cutting edge is fixed seat front end, and cutting edge is fixed seat 42 and fixed seat by cutting edge and fix bolt 44 and be fixedly connected in rotary shaft 21.Cutting edge 41 highlights installation and is connected to cutting edge and fixes on side, seat 42 front end, and blade is towards control valve stand base to be repaired.Speed change gear 20 is provided with feed regulating lever 50, adjusts the regulation repairing Tool advance amount that feed regulating lever 50 realizes.Feed regulating lever is connected with speed change rotary shaft.Stationary positioned pedestal 10 has step-like ring-type fixed base frame, and adpting flange 11 is fixedly connected on the step body end of less external diameter.Cutting edge is fixed seat and is provided with cutting edge installation passage 44 radially and axial cutting edge installation secured adjusted screwed hole 45, and cutting edge cutter hub is fixed on cutting edge and installs on passage 44.Cutting edge is fixed and is had installation Orientation observation hole 46 on seat 42, and more convenient observation cutting edge fixes that the peace and quiet between seat 42 with rotary shaft 21 are fixing is connected effect.Cutting edge has rotary shaft and installs passage 47 in fixing seat 42 axle center, rotary shaft is installed passage 47 and had the step-like installation passage of size difference in internal diameters, improves and installs stationary positioned effect.
The cutting edge regulation valve to be repaired repairing cutter grinds, and the edge of a knife is narrower, and cutting edge regulates length according to control valve stand size, and is fixed on cutting edge and fixes on seat.Provide more suitable service kit, the regulation valve of seat bottom portion blow loss can be repaired, make the valve seat base of blow loss, particularly when by serious blow loss, can effectively return to original diameter and the degree of depth, and reach flatness and the fineness of requirement.Additionally can directly operate without at Overhaul site otherwise cut off valve and overhaul, maintenance workload and repair time can be greatly reduced.After reparation as regulation valve first wife, after running after a while, all leak, eliminate valve seat because of a large amount of stove water leakage after blow loss.
As a example by repairing #5 stove second trace Desuperheating water regulating valve (model C OPES-VULCAN), calculating the produced benefit of current transformation: 1. allow the valve almost scrapped return to first wife the same, the Desuperheating water regulating valve U.S. copes that my company uses needs 100,000.2. can process at the scene with rotary cut device rotary-cut, valve need not be cut off, save manpower, saved for 10 man-hours, about 800 yuan.After valve seat blow loss, the leakage of a large amount of stove water, necessarily causes reheater outlet temperature to reduce, economy reduction, with leakage rate 5 tons per hour, calculates as a example by gross coal consumption rate 300g/kWh, and economize on coal 1.998g/kW.h, economizes on coal 1.998 × 215000 × 4500 × 10 every year-6=1933 tons of standard coals, annual saving fund 1933 × 600=1159800 is first.
Although the most more employing the terms such as stationary positioned structure, rotary shaft, reparation cutter, motor and speed change gear；But it is not precluded from using the probability of other term.Use these terms to be only used to more easily to describe and explain the essence of the present invention；It is all contrary with spirit of the present invention for being construed as any additional restriction.
