Description
Technical field：
The utility model is related to a kind of extracting tool, more particularly to a kind of boiler blocks up the itself dismounting special tool of valve
Tool.
Background technology：
At present, it is necessary to repeatedly be dismounted to stifled valve when the boiler in thermal power plant carries out the water pressure test；Enter every time
The row water pressure test then takes out flow guide sleeve, it is necessary to first remove the itself on stifled valve from stifled valve, and by closure plate and support plate
Load etc. internals in stifled valve, it is necessary to remove the internals such as closure plate and support plate and installation water conservancy diversion inside stifled valve after the completion of the water pressure test
Also need to again remove itself from stifled valve during set；There are multiple stifled valves, the required number of times dismounted on every boiler
More, the weight of each itself has more than 200 kilograms, and has self sealss packing ring to be inserted into the surrounding in itself；At present, it is right
Itself is removed using guide chain is connected on the suspension ring of itself center, then draws high lifting, and copper is used during drawing high
Rod or sledgehammer constantly shake itself to keep itself level；But more than use remove mode and there is following ask
Topic：1st, it is necessary to which multiple staff coordinate, while percussion dynamics of the staff to itself, frequency in demolishing process
And draw high power and be difficult to reach perfect cooperation, itself is stuck on stifled valve easily there is inclination, it is impossible to smoothly to remove,
Need repeatedly to can be only achieved dismounting purpose, waste time and energy；2nd, while staff is entered using copper rod or sledgehammer to itself
Row is tapped, and certain work risk is added for staff.
Utility model content：
The purpose of this utility model is to provide a kind of simple in construction, time saving and energy saving, remove convenient boiler block up valve from
Seal tool special for dismounting.
The utility model is implemented by following technical scheme：A kind of boiler blocks up the itself tool special for dismounting of valve, and it is wrapped
Supporting plate is included, bar hole is offered in the supporting plate, is slided in the bar hole very heavy provided with two Split type hydraulics
The fixed sliding block in top；Fixed in each Split type hydraulic jack on sliding block bottom surface and be fixed with a piston rod straight down
The Split type hydraulic jack of stretching；Two Split type hydraulic jack with it is double go out hydraulic hand-pump be connected by pipeline；
Activity grafting in the bar hole between sliding block, which is fixed, in two Split type hydraulic jack is provided with two threaded rods,
Nut is bolted with the threaded rod above the supporting plate.
Advantage of the present utility model：1st, threaded rod is screwed in the screwed hole of itself, operates Split type hydraulic thousand
Jin top, and observe bar formula level meter, it is ensured that itself can be removed from level on stifled valve, it is to avoid itself occurs
Situation about being stuck on stifled valve is tilted, smoothly itself is removed, it is multiple without removing, it is time saving and energy saving；2nd, in demolishing process,
Coordinate without several staff, reduce cost of labor；3rd, itself is tapped without using copper rod or sledgehammer,
It ensure that the work safety of staff；4th, it is simple in construction, it is easy to operate.
Brief description of the drawings：
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is Fig. 1 top view.
Fig. 3 is Fig. 1 sectional view.
Fig. 4 is use schematic diagram of the present utility model.
Supporting plate 1, bar hole 2, Split type hydraulic jack fixes sliding block 3, Split type hydraulic jack 4, piston rod
4.1, it is double go out hydraulic hand-pump 4.2, threaded rod 5, nut 6, block up valve 7, itself 8, screwed hole 8.1.
Embodiment：
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of boiler blocks up the itself tool special for dismounting of valve, and it includes supporting plate 1, in branch
Bar hole 2 is offered on fagging 1, is slided in bar hole 2 and fixes sliding block 3, Ke Yitong provided with two Split type hydraulic jack
Two Split type hydraulic jack of slip are crossed to fix sliding block 3 and then adjust the distance between two Split type hydraulic jack 4；
Each Split type hydraulic jack fixes be fixed with that a piston rod 4.1 stretches out straight down on the bottom surface of sliding block 3 split type
Hydraulic jack 4；Two Split type hydraulic jack 4 with it is double go out hydraulic hand-pump 4.2 be connected by pipeline；Two split type liquid
Pressing jack to fix activity grafting in the bar hole 2 between sliding block 3, can activity tune in bar hole 2 provided with two threaded rods 5
Save the spacing of two threaded rods 5；Nut 6 is bolted with the threaded rod 5 of the top of supporting plate 1.
Operation instruction：As shown in figure 4, adjustment two threaded rods 5 spacing, make two threaded rods 5 respectively with stifled valve 7
Two relative screwed holes 8.1 are aligned on the center line of itself 8, by the precession screwed hole 8.1 of threaded rod 5；Again by sliding
Split type hydraulic jack fixes sliding block 3 to adjust the spacing of two Split type hydraulic jack 4, makes two Split type hydraulics thousand
Jin top 4 is individually positioned in above the housing of the stifled valve 7 in the outside of itself 8；Two nuts 6 are rotated, make two nuts 6 and support
The surface of plate 1 is brought into close contact；Then operation pair goes out hydraulic hand-pump 4.2, makes two jack-up supporting plates 1 of Split type hydraulic jack 4
Height it is identical, and then the height for being raised above two threaded rods 5 is identical, it is ensured that itself 8 can be vertically from stifled valve 7
Split out, it is to avoid the run-off the straight in demolishing process of itself 8 is stuck in stifled valve 7, it is impossible to smooth to take out；Simultaneously without making
Tapped with instruments such as copper rod or sledgehammers, it is ensured that the security of staff.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modifications, equivalent substitutions and improvements made etc. should be included in the utility model
Protection domain within.
