Description
Technical field
The utility model relates to pipeline valves to dismount maintenance tool technical field, refer specifically to a kind of oil and gas pipeline valve
Door extracting tool.
Background technique
Valve is the important accessory of oil-gas pipeline, for controlling and adjusting rate-of flow in pipeline.Since valve is often grasped
Make, sealing and adjustment effect fail often, need replacing pipeline valve.In valve disassembly and in the process, due to two of valve
Flange is connected with gasket with the flange of pipeline by steel ring, during prolonged use, steel ring and the same method of gasket
Orchid is completely embedded, and valve does not take not come out, if directly being pulled open by force with lifting appliance, easily cause flange sealing surface and gasket by
Damage；In the new valve installation of replacement, since the flange of pipeline two sides has been fixed, the interval very little of mountable valve, steel ring
With gasket is more difficult puts in, misoperation is likely to cause gasket damage, steel ring scratch and personnel and squeezes wound.Therefore,
The existing technology needs to be improved and developed.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of structurally reasonable, reduction dimension is provided
The labor intensity for repairing personnel prevents the oil and gas pipeline valve extracting tool of personal injury.
To achieve the goals above, the utility model uses following technical scheme：
A kind of oil and gas pipeline valve extracting tool described in the utility model, including telescopic rod, the two of telescopic rod
End is equipped with expanding nut and expansion screw, and expansion screw is equipped with expansion fixture；The expansion fixture include location nut,
Inner splint, adjusting nut, external splint and fixture nut, expansion screw sequentially pass through location nut, inner splint one end pilot hole,
Adjusting nut, the pilot hole of external splint one end and fixture nut.
According to above scheme, several levelling pads are equipped between the adjusting nut and external splint.
According to above scheme, the other end of the inner splint is equipped with limitation screw hole, the other end of external splint be equipped with
The opposite through-hole of screw hole is limited, and is equipped with the bolt connecting with limitation screw hole in through-hole.
The utility model has the beneficial effect that：The utility model is structurally reasonable, is fixed by the expansion fixture at telescopic rod both ends
The flange at valve both ends, inner splint and external splint one end are fixed on expansion screw, inner splint and external splint other end chucking method
Orchid is simultaneously bolted, and then rotating extensible arm is strutted by the opposed helical displacement between expanding nut and expansion screw
Two flanges reduce maintenance difficulties and avoid personal injury to provide the space of the dismounting maintenance of enough valves.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
In figure：
1, telescopic rod；2, location nut；11, expanding nut；12, expansion screw；21, inner splint；22, adjusting nut；23,
External splint；24, fixture nut；25, screw hole is limited；26, through-hole.
Specific embodiment
The technical solution of the utility model is illustrated with embodiment with reference to the accompanying drawing.
As shown in Figure 1, a kind of oil and gas pipeline valve extracting tool described in the utility model, including telescopic rod 1,
The both ends of telescopic rod 1 are equipped with expanding nut 11 and expansion screw 12, and expansion screw 12 is equipped with expansion fixture；The expansion
Fixture includes location nut 2, inner splint 21, adjusting nut 22, external splint 23 and fixture nut 24, and expansion screw 12 sequentially passes through
Location nut 2, the pilot hole of 21 one end of inner splint, adjusting nut 22, the pilot hole of 23 one end of external splint and fixture nut 24；Institute
It states and is equipped with several levelling pads between adjusting nut 22 and external splint 23, the other end of the inner splint 21 is equipped with limitation screw hole
25, the other end of external splint 23 is equipped with the through-hole 26 opposite with limitation screw hole 25, and is equipped in through-hole 26 and limitation screw hole
The bolt of 25 connections；The telescopic rod 1 is made by seamless steel pipe, and expanding nut 11 is welded to cooperate expansion screw 12 in both ends, is stretched
The expanding nut 11 at 1 both ends of contracting bar and the hand of thread spiral of expansion screw 12 are on the contrary, to which telescopic rod 1 makes both ends in rotation
Expansion fixture composition synchronize and extend out or the effect of synchronous；Described two inner splints 12 are first according to valve two sides flange plate
Spacing determine relative position, and, right latter two inner splint 12 other end insertion two fixed by location nut 2 and adjusting nut 22
Between a flange plate, then installing external splint 23 makes its other end cooperation inner splint 12 clamp flange plate, is adjusted by levelling pad
Through-hole 26, flange plate fixation hole and limitation screw hole 25 are passed through with bolt after curb pins plate spacing, makes to expand fixture and flange plate is solid
Fixed connection changes the spacing between two expansion fixtures and flange plate eventually by the rotation of telescopic rod 1, reserves sufficient space
In order to which the dismounting of valve is safeguarded；Medium in natural gas line should be first laid down before above-mentioned dismounting process, through detection no pressure and
Toxic and harmful gas, the bolt of dismantling connection flange stay a bolt not tear open, as the insurance of firm valve, prevent valve prominent
So fall.
The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range
The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
