Description
Technical field
The technical field of pipeline connection that the utility model belongs in oilfield operation, specially a kind of union nut dismounting is pulled
Hand.
Background technology
In oilfield operation, union is a kind of standarized component of conventional pipeline connection.It has sealed reliable, pressure-bearing
Ability is high, general interchangeability is good, can motionless pipeline and by two pipes dismount easy access the advantages of.By being made in oilfield operation
Union is chronically at field, and bears after high pressure Korrosionsmedium, therefore a period of time use, the screw thread meeting of union nut
There is the phenomenon such as corrosion, stuck, at this moment when overhauling pipeline dismounting union nut, it may appear that dismounting is difficult can not even to dismantle
Situation, can only make repeated attempts when generally occurring within this phenomenon by manpower, and labor intensity is big, and dangerous.
The tightening torque of conventional union nut hammers the wing of nut to apply mainly by operating personnel with more than 5kg hammers
Plus.And in practical operation, because the wing of nut is too small, hammering of the operating personnel to the wing maximized can not be converted into nut
Torque so that getting half the result with twice the effort, increase the labor intensity of operating personnel.Or operating personnel operating space is narrow and small, hammer
Activity space it is inadequate, it is impossible to apply bigger hammer force.Even some accurate pressure sensors are directly installed on wing spiral shell
Female inside is simultaneously compressed, and is closely hammered and is easily damaged sensor.
The content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency there is provided a kind of union nut wrench for dismounting, is directly sleeved on oil
In the union nut of field equipment manifold, mitigate manipulation strength.
To realize above-mentioned technical purpose, the scheme that the utility model is provided is：A kind of union nut wrench for dismounting, it is described by
Nonyl nut is wing nut, including driving end, hammering seat and handle, and the driving end is the loop configuration with opening, spanner
The groove that uniform multiple wing structures with union nut match in the inner ring of head, the outer shroud of driving end is provided with raised handle
Both sides in shape structure positioned at spanner direction of rotation, are respectively equipped with hammering seat, the handle is connected with shape structure by shape structure.
Moreover, the groove in the driving end inner ring has 1 ~ 6.
Moreover, the hammering seat by screw be installed on driving end in shape structure, or, it is described hammer seat and be welded in pull
At hand in shape structure, or, the hammering seat and driving end is an entirety shape structure.
Moreover, the handle is rod-like structure, it is inserted directly into handle hole of the driving end shape structure, or, it is with pulling
Shape structure is threadedly coupled at hand, or, it is anchored on driving end in shape structure by screw.
The beneficial effects of the utility model are：In the union nut that oil field equipment manifold can be directly sleeved on, it can both increase
Plus moment of torsion, mitigate the labor intensity of operating personnel, lift disassembly efficiency, can be installed again in small space by handle, more
Avoid closely by mistake hammering precision pressure sensor cause economic loss.

Embodiment
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
The present embodiment provides a kind of union nut wrench for dismounting, and the union nut 1 is wing nut, as shown in Figure 1.By
Nonyl nut wrench for dismounting includes driving end 6, hammering seat 10 and handle 11, as shown in Fig. 2 the driving end 6 is with opening 12
Loop configuration, the groove 7 that uniform multiple structures of the wing 4 with union nut 1 match in the inner ring of driving end 6, driving end 6
Outer shroud provided with raised shape structure 9, the both sides that spanner direction of rotation is located in shape structure 9 are respectively equipped with hammering seat
10, the handle 11 is connected with shape structure 9.
The circumference upper shed 12 of driving end 6, is easy to reach on pipeline, during operation as shown in Figure 3 and Figure 4, on driving end 6
Opening 12 is horizontally through male pipe 3, and driving end 6 is moved horizontally along the axis of male pipe 3 to union nut 1, until groove 7 and union
The wing 4 of nut 1 mutually agrees with, and the groove end face 8 on driving end 6 sticks nut end face 5, and completion driving end 6 is stung with union nut 1
Close.
The groove 7 being consistent with the planform of the wing 4 of nut is processed on driving end 6, groove 7 can directly block nut
The wing 4.
Hammering seat 10 is installed on driving end 6, with the hammering of hammer striking wrench first 6 seat 10, can play pound it is tight or loosen by
The effect of nonyl nut 1.
Handle 11 can be installed on driving end 6 additional, when that can not hammer, moment of torsion, profit can be applied with the handle 11 of suitable length
With the rotary spanner of handle 11 first 6 to turn nut, completion is tightened or unscrews union nut 1.
Further, the groove 7 in the inner ring of driving end 6 has 1 ~ 6.
Further, the hammering seat 10 by screw be installed on driving end 6 in shape structure 9, or, the hammering seat
10 be welded in driving end 6 in shape structure 9, or, the hammering seat 10 is an entirety shape structure 9 with driving end 6.
Further, the handle 11 is rod-like structure, and it is inserted directly into handle hole of the driving end 6 shape structure 9,
Or, it is threadedly coupled shape structure 9 with driving end 6, or, it is anchored on driving end 6 in shape structure 9 by screw.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvement or deformation can also be made, these improve or
Deformation also should be regarded as protection domain of the present utility model.
