Description
Technical field
This utility model relates to oil natural gas probing class downhole tool technical field, is specifically related to a kind of for boring
The rotation changement of well tool.
Background technology
At present, it is many that changement is mainly ground machine Application comparison, use manually more, mechanical commutation and
Circuit controls commutation.Oil-gas drilling process, the medium owing to using is mixing of water and mud, sand etc.
Compound, it is desirable to necessary wear-resisting, the erosion resistance of changement and simple in construction, presently disclosed changement is all
Requirement can not be met.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rotation reversing machine for drilling tool
Structure is in conjunction with being actually needed of oil-gas drilling industry, wear-resisting durable.
For achieving the above object, the technical scheme that this utility model is taked is:
A kind of rotation changement for drilling tool, including cylinder body, drive shaft and reversal valve, described cylinder
The external outer tube that is arranged with, and cylinder body end face contacts fixing with step surface in outer tube, cylinder body other end sets
Having top connection, top connection is threadably secured with outer tube and is connected, and is fixed with cylinder sleeve in cylinder body, sliding in cylinder sleeve
Move and be equipped with hollow piston, be connected in described driveshaft end stretches into top connection and with reversal valve, reversal valve
In rotation is assemblied in cylinder body and being connected with liner packing, drive shaft is connected with drive mechanism, described cylinder body,
Reversal valve is made by alloy material.
Described reversal valve is threadedly secured in drive shaft.
Described cylinder sleeve is threadably secured in cylinder body.
Reversal valve of the present utility model, cylinder sleeve are made up of alloy material, and it is high that it has pressure-bearing, punching wear-resisting, resistance to
Erosion property, service life is long, it is possible to meet being actually needed of oil-gas drilling industry, this device simultaneously
Simple in construction is easily changed；Drive shaft is driven by drive mechanism, can directly change drive mechanism, meets difference
Demand, easy to use.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As Figure 1-Figure 4, a kind of rotation changement for drilling tool, including cylinder body 4, drives
Moving axis 2 and reversal valve 3, be arranged with outer tube 6 outside cylinder body 4, and cylinder body 4 end face and step in outer tube 6
Face contact is fixing, and cylinder body 4 other end is provided with top connection 1, and top connection 1 is threadably secured with outer tube 6
Connecting, be fixed with cylinder sleeve 5 in cylinder body 4, in cylinder sleeve 5, slidable fit has hollow piston 7, driveshaft end
Being connected in stretching into top connection and with reversal valve, reversal valve rotates in being assemblied in cylinder body and is connected with liner packing,
Drive shaft is connected with drive mechanism, and described cylinder body, reversal valve are made by alloy material, its have wear-resisting,
Abrasion-resistance and simple in construction are easily changed.
Reversal valve 3 is threadedly secured in drive shaft 2, and cylinder sleeve 5 is threadably secured in cylinder body 4,
Convenient handling, it is simple to maintenance is changed.
When this utility model is specifically used, drive shaft 2 produces rotation under the drive of drive mechanism；Commutation
When valve 3 flows through drilling fluid, due to the change of passage, producing pressure change, reversal valve 3 upper pressure is big
In low pressure, forming higher-pressure region, top, bottom low-pressure area, when reversal valve 3 is in the drive of drive shaft 2
Lower when rotating, the upper and lower cavity of reversal valve lower channel and cylinder sleeve 5 interlocks UNICOM, it is achieved cylinder body upper and lower cavity
Pressure is changed back and forth, drives hollow piston 7 to move back and forth with this.
Claims (3)
