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, and is distant apart from the valve casing collar extension.Yet the valve seat that has does not possess the lifting screw hole when assembling, and valve seat itself need cool off with dry ice or liquid nitrogen, so just causes valve seat in assembling, cannot directly to contact with hand, thereby assembling is caused certain difficulty.And valve seat originally can only be operated from upper surface in the process of assembling; Lower surface is in valve casing inside; Distance apart from valve casing is suitable for reading is distant; And, can't carry out the operations such as degree of tightness of bolt and nut etc. to the valve seat base section because the internal diameter of valve seat own is less, this just requires certain instrument that the assembling of valve seat is assisted.
Steam turbine plant adopts both sides clamping plate 8 more in the assembling valve seat at present, and the method for lifting by crane behind the middle bolt together is as shown in Figure 1.This seat assembling tool for valve does not have secondary operation property, and this instrument can only assemble with valve seat before the valve seat assembling.Because valve seat 9 is operated the side from it itself, this just defines valve seat 9 assembling in a single day when assembling and accomplishes, and instrument is disassembled the back just can't operate in valve casing inside, thereby can't revise once more valve seat 9.When needs remove when ressembling valve seat, just produced difficulty.
Summary of the invention
The objective of the invention is provides a kind of steam turbine seat assembling tool for valve for overcoming the deficiency of above-mentioned prior art, and this fitter's tools commonality is good; Simple in structure, clamping, convenient disassembly, fast easy to operate; But the disassemble and assemble work between implementation tool and the valve seat both can be installed valve seat, can dismantle valve seat again; Need not stretch into the valve seat bottom and remove dismantling devices, high efficiency.
For realizing above-mentioned purpose, the present invention adopts following technical proposals:
A kind of steam turbine seat assembling tool for valve; Comprise the sleeve telophragma, be penetrated with in one in the said sleeve telophragma and carry core, in carry core the lower end be hinged with two relative extendible and retractable dog; Be provided with horizontal concrete chute in the extendible and retractable dog, sleeve telophragma lower end is inserted in the horizontal concrete chute through bearing pin; Be fixed with bolt and nut on the sleeve telophragma, top board is passed in the bolt upper end, and fastening through nut.
Establish on the said extendible and retractable dog and also be provided with cushion block.
The longitudinal cross-section of said sleeve telophragma is inverted T-shape.
Cushion block of the present invention is fixed on the extendible and retractable dog; Extendible and retractable dog inboard with in to carry core hinged; Slide relative with the bearing pin form between extendible and retractable dog centre portion and the sleeve telophragma is connected.During the assembling valve seat, take off top board and bolt and nut, valve seat is placed above the supporting tool, carry core in inciting somebody to action and push away downwards, extendible and retractable dog inwardly is contracted to (littler than valve seat bore at least) on the certain diameter like this.After this instrument is put into valve seat endoporus the inside, carries core in upwards mentioning and upwards carry, extendible and retractable dog is in open configuration, catches the valve seat bottom, and the valve seat upper surface is put the top board bolt and nut of screwing on, thereby with fixing between valve seat and the fitter's tools.When needs are dismantled, otherwise operation gets final product.
The invention has the beneficial effects as follows, for the valve seat bore difference little can be general, the adjustment cushion block level attitude, can the valve seat of different inner diameters be assembled.Convenient mounting and clamping is fast easy to operate; After screw-nut and top board directly remove from the top; Only need to carry in the push-and-pull core and get final product the disassemble and assemble work between implementation tool and the valve seat, both can install, can dismantle valve seat again valve seat; Need not stretch into the valve seat bottom and remove dismantling devices, increase work efficiency.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
As shown in Figure 2; The steam turbine seat assembling tool for valve; Comprise sleeve telophragma 4, be penetrated with in the said sleeve telophragma 4 and carry core 7 in one, in carry core 7 the lower end be hinged with two relative extendible and retractable dog 1; Be provided with horizontal concrete chute 10 in the extendible and retractable dog 1, sleeve telophragma 4 lower ends are inserted in the horizontal concrete chute 10 through bearing pin 3; Be fixed with bolt and nut 6 on the sleeve telophragma 4, top board 5 is passed in the bolt upper end, and fastening through nut.
Establish on the extendible and retractable dog 1 and also be 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.
Though the above-mentioned accompanying drawing specific embodiments of the invention that combines is described; But be not restriction to protection domain of the present 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 need not pay various modifications that creative work can make or distortion still in protection scope of the present invention.
