Description
Technical field
The utility model is related to a kind of extracting tool, specifically a kind of safety valve guide sleeve removal tool special belongs to
In extracting tool field.
Background technology
Valve rod moves vertically when valve rises, returns seat, avoids the safe defective valve caused by valve rod deflection.Main steaming in boiler of power plant
Vapour, reheated steam outlet temperature are high, and longtime running causes guide sleeve to be tightly combined with valve seat, is oriented in safety valve Disintegration overhaul
Set is inconvenient to dismantle.Since safety valve inner space is smaller, conventional tool cannot be placed wherein, thus generally be utilized when disintegration
The tools such as copper rod carry out rapping to guide sleeve, slowly take out guide sleeve.
However, inevitably guide sleeve can be caused to damage using this kind of method, long-term disintegrate even can bring safety valve
The consequences such as failure；In addition this method working efficiency is low, using artificial more, causes certain wasting of resources.
Invention content
To solve the above-mentioned problems, the utility model devises a kind of safety valve guide sleeve removal tool special, uses behaviour
Facilitate, improve work efficiency, while reducing the damage to guide sleeve.
The technical solution of the utility model is：
Safety valve guide sleeve removal tool special, the extracting tool include lifting plate；There are two the lifting plate is set, cut
Face is arch, and it is circular arc that one side is contacted with the guide sleeve, and arc radius is slightly less than guide sleeve internal diameter；Under the lifting plate
Portion is equipped with a protrusion, and guide sleeve lower end is held when for dismantling guide sleeve；The centre of the lifting plate is equipped with an internal thread hole, with
Width adjusting bar is threadedly coupled；
The both ends of the width adjusting bar are equipped with screw thread, meanwhile, screw thread described in both ends oppositely oriented and with the promotion
Plate neutral threaded hole matches；The centre of the width adjusting bar is cuboid, inside there is a threaded hole, is connected with enhancing screw screw thread
It connects；According to the size of safety valve, the dismantlement work of guide sleeve can be carried out by using the mode of the width adjusting bar of different length.
Further, the enhancing screw main body is helicitic texture, is matched with the width adjusting bar；Lower part is obtuse angle
Round end, when use, are placed on valve base of safety valve, avoid that valve seat is caused to damage；Top is six face cylinders, and when use is grasped with spanner
Make.
Further, the top of the lifting plate is equipped with a lifting lug.
Method for dismounting is specific as follows：
（1）Two pieces of lifting plates are threaded on width adjusting bar, are rotated inwardly, reduce two lifting plate intermediate distances, and lead to
Crossing adjustment keeps lifting plate consistent apart from width adjusting bar centre distance；
（2）Lifting plate and width adjusting bar are put into inside safety valve using lifting lug, adjustment width adjusting rod makes two pieces to carry
Lift slab protrusion is placed on guide sleeve and raises in the gap among ring, while adjusting width adjusting bar so that its centre bore is in vertical
Straight position；
（3）Enhancing screw is screwed into the centre bore of width adjusting bar, is screwed in downwards, so that enhancing screw lower part round end
It is contacted with valve seat, utilizes six face cylinder of spanner rotation enhancing screw top later, guide sleeve can smoothly be taken out.
The utility model has the advantage of：Dismounting is steady, and use is easy to operate, improves work efficiency, while greatly
Safety valve attachment is protected, the damage to guide sleeve is reduced.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Description of the drawings
Fig. 1 is safety valve guide sleeve figure；
Fig. 2 is the structural schematic diagram of the utility model embodiment extracting tool.
Specific implementation mode
The preferred embodiment of the utility model is illustrated below, it should be understood that preferred embodiment described herein
It is only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
