Abstract
The invention discloses a valve seat assembly tool of a turbine, which comprises a sleeve middle disc. An inner lifting core penetrates through the sleeve middle disc, the lower end of the inner lifting core is hinged with two opposite retractable claws, a horizontal sliding groove is arranged in each retractable claw, and the lower end of the sleeve middle disc is inserted in the horizontal sliding grooves through pin rolls. A bolt and a nut are fixed on the sleeve middle disc, and the upper end of the bolt penetrates through an upper press plate and is fastened through the nut. The valve seat assembly tool can be generally used for valve seats with inner diameters with small differences, the horizontal position of cushion blocks is adjusted, and the valve seats with different inner diameters are assembled. Clamping is convenient, rapid and east to operate, after the bolt, the nut and the upper press plate are directly disassembled from the top portion, users only need push and pull the inner lifting core to achieve dismounting work between the tool and the valve seat, so that the valve seat is installed and dismounted, the users do not need to stretch into the bottom of the valve seat to dismount the tool, and work efficiency is improved.
Description
Technical field
The present invention relates to a kind of fitter's tools, especially a kind of steam turbine seat assembling tool for valve.
Background technology
In steam turbine valve seat fitting process, valve seat is positioned at valve casing inside, distant apart from valve casing collar extension.Yet some valve seats time do not possess hoisting screw hole in assembling, and that valve seat itself need to carry out with dry ice or liquid nitrogen is cooling, so just causes valve seat cannot directly to contact with hand in assembling, thereby causes certain difficulty to assembling.And valve seat originally can only operate from upper surface in the process of assembling, lower surface is inner in valve casing, distant apart from the distance that valve casing is suitable for reading, and because the internal diameter of valve seat own is less, cannot to valve seat base section, carry out the operations such as degree of tightness of bolt and nut etc., this just requires certain instrument to assist the assembling of valve seat.
Steam turbine plant adopts both sides clamping plate 8 more in assembling valve seat at present, the method that lift by crane after connecting with bolt centre, as shown in Figure 1.This seat assembling tool for valve does not have secondary operation, and this instrument can only assemble with valve seat before valve seat assembling.Because valve seat 9 can only operate from the upper side itself, once just defining valve seat 9, this when assembling, has assembled, after instrument is disassembled, just cannot operate in valve casing inside, thereby cannot again revise valve seat 9.When needs remove while ressembling valve seat, just produced difficulty.
Summary of the invention
The object of the invention is for overcoming above-mentioned the deficiencies in the prior art, a kind of steam turbine seat assembling tool for valve is provided, this fitter's tools commonality is good, simple in structure, clamping, convenient disassembly, fast easy to operate, can implementation tool and valve seat between disassemble and assemble work, both can install valve seat, can dismantle valve seat again, do not need to stretch into valve seat bottom and remove dismantling devices, work efficiency is high.
For achieving the above object, the present invention adopts following technical proposals:
A kind of steam turbine seat assembling tool for valve, comprise sleeve telophragma, in described sleeve telophragma, be penetrated with in one and carry core, the lower end of inside carrying core is hinged with two relative extendible and retractable dog, in extendible and retractable dog, be provided with horizontal concrete chute, sleeve telophragma lower end is inserted in horizontal concrete chute by bearing pin; On sleeve telophragma, be fixed with bolt and nut, top board is passed in bolt upper end, and passes through fastening nuts.
On described extendible and retractable dog, establish and be also provided with cushion block.
The longitudinal cross-section of described sleeve telophragma is inverted T-shape.
Cushion block of the present invention is fixed on extendible and retractable dog; Extendible and retractable dog inner side with in to carry core hinged; Relative sliding with bearing pin form between extendible and retractable dog centre portion and sleeve telophragma is connected.During assembling valve seat, take off top board and bolt and nut, valve seat is placed in above supporting tool, carry core and push away downwards in inciting somebody to action, extendible and retractable dog is inwardly contracted to (at least little than valve seat bore) on certain diameter like this.This instrument is put into behind valve seat endoporus the inside, carries core and upwards carry in upwards mentioning, extendible and retractable dog, in open configuration, catches valve seat bottom, and valve seat upper surface is put the top board bolt and nut of screwing on, thereby will between valve seat and fitter's tools, be fixed.When needs are dismantled, on the contrary operation.
The invention has the beneficial effects as follows, for valve seat bore difference little can be general, adjust the level attitude of cushion block, can assemble the valve seat of different inner diameters.Convenient mounting and clamping is fast easy to operate, when screw-nut and top board are from top directly removes, only need to carry core in push-and-pull and get final product the disassemble and assemble work between implementation tool and valve seat, both can install valve seat, can dismantle valve seat again, do not need to stretch into valve seat bottom and remove dismantling devices, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is prior art structural representation;
Fig. 2 is structural representation of the present invention;
1. extendible and retractable dog wherein, 2. cushion block, 3. bearing pin, 4. sleeve telophragma, 5. top board, 6. bolt and nut, carries core in 7., 8. clamping plate, 9. valve seat, 10. horizontal concrete chute.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 2, steam turbine seat assembling tool for valve, comprise sleeve telophragma 4, in described sleeve telophragma 4, be penetrated with and in one, carry core 7, the lower end of inside carrying core 7 is hinged with two relative extendible and retractable dog 1, in extendible and retractable dog 1, be provided with horizontal concrete chute 10, sleeve telophragma 4 lower ends are inserted in horizontal concrete chute 10 by bearing pin 3; On sleeve telophragma 4, be fixed with bolt and nut 6, top board 5 is passed in bolt upper end, and passes through fastening nuts.
On extendible and retractable dog 1, establish and be also provided with cushion block 2, cushion block 2 plays location and supporting role.
The longitudinal cross-section of sleeve telophragma 4 is inverted T-shape.
Cushion block 2 of the present invention is fixed on extendible and retractable dog 1; Extendible and retractable dog 2 inner sides with in to carry core 7 hinged; Relative sliding with bearing pin 3 forms between extendible and retractable dog 1 centre portion and sleeve telophragma 4 is connected.During assembling valve seat, take off top board 5 and bolt and nut 6, valve seat 9 is placed in above supporting tool, carry core 7 and push away downwards in inciting somebody to action, extendible and retractable dog 1 is inwardly contracted to (at least little than valve seat 9 internal diameters) on certain diameter like this.This instrument is put into behind valve seat 9 endoporus the insides, carries core 7 and upwards carry in upwards mentioning, extendible and retractable dog 1, in open configuration, catches valve seat 9 bottoms, and valve seat 9 upper surfaces are put top board 5 bolt and nut 6 of screwing on, thereby will between valve seat 9 and fitter's tools, be fixed.When needs are dismantled, on the contrary operation.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
