Description
Technical field
The utility model relates to a kind of tunable center washing pipes in drilling equipment, especially oil drilling.
Background technique
During wellbore construction, tap is one of essential equipment in drilling equipment, and washing pipe assembly is again
One of critical component of tap is tap rotation and non rotatable engaging portion, is composed for multi-part, needs multipart
High-precision cooperation needs to seal with one heart up and down in washing pipe rotary course to guarantee that channel is unblocked, but due to the problem in structure,
Automatic aligning problem is not can solve, washing pipe machining accuracy is high again, also occurs the phenomenon that decentraction in an assembling process unavoidably, influences
The service life of product, and in drilling process, it since tap is used continuously for a long time, wears, occurs between washing pipe and sealing element
Gap leads to seal failure, and water tap washing pipe assembly will appear drilling fluid leakage, and rig floor security context and downhole safety are by shadow
It rings, it has to it stops working and replaces washing pipe assembly, but it is extremely inconvenient to replace condition, and is eminence hanging operation, neither just
Just, and dangerous, therefore, the improvement and innovation on washing pipe are imperative.
Utility model content
For above situation, for the defect for overcoming the prior art, the purpose of the utility model is to provide a kind of tunable center
Washing pipe, can effectively solving existing washing pipe, to be unable to automatic aligning, drilling fluid leakage, service life short, replaces inconvenient problem.
The technical solution that the utility model solves is, including union, aligning washing pipe and sealing ring, and the union is hollow circle
Cylinder, center bore inner wall is in step-like, and internal screw thread is arranged at center bore inner wall top, and union outer wall is evenly equipped with several convex blocks on periphery,
Aligning washing pipe is that top is cylindrical in step-like clear opening, step plane patch in the step and union of aligning washing pipe upper end lower part
It is combined, union circle center can swing the concentricity of adjustment aligning washing pipe and tap, union and the decentraction of aligning washing pipe
Swing, the upper surface of aligning washing pipe is provided with annular seal groove, and annular seal groove is provided with sealing ring, aligning washing pipe lower end pass through by
The centre bore of nonyl, the internal screw thread through union are fixed on tap together with the external screw thread spinning on tap, by aligning washing pipe
On.
The utility model structure is simple, and novel and unique is easy to install and use, and using effect is good, extends making for washing pipe assembly
It with the service life, economizes on resources, improves the safety of drill body operation, economic and social benefit is significant.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the structure of the utility model.
Specific embodiment
It elaborates below in conjunction with attached drawing and particular condition in use to specific embodiment of the present utility model.
As shown in Figure 1, a kind of tunable center washing pipe of the utility model, including union 1, aligning washing pipe 3 and sealing ring 2, institute
Stating union 1 is hollow cylinder, and for 5 inner wall of centre bore in step-like, 5 upper inside wall of centre bore has internal screw thread 1-1,1 outer wall of union
Several convex blocks 6 are evenly equipped on periphery, aligning washing pipe 3 is that top is cylindrical in step-like clear opening, 3 upper end lower part of aligning washing pipe
Step 3-4 fit together with step plane in union 1,1 circle center of union can swing adjustment aligning washing pipe 3 and tap
Concentricity, union（1）With aligning washing pipe（3）Decentraction is swung, and the upper surface of aligning washing pipe 3 is provided with annular seal groove 3-6, ring
Shape seal groove 3-6 is provided with sealing ring 2, and 3 lower end of aligning washing pipe passes through the centre bore 5 of union 1, the internal screw thread 1-1 through union 1 with
Aligning washing pipe 3 is fixed on tap by the external screw thread spinning on tap together.
In order to guarantee using effect and easy to use,
The sealing ring 2 is ring-shaped rubber sealing element.
The convex block is 6, is tightened or is dismantled for hammer tool.
The bore of the centre bore 5 of the union 1 is greater than the bore of the clear opening 3-5 of aligning washing pipe 3.
The bore of the centre bore 5 of the union 1 is greater than the outer diameter of the step 3-1 on the top of aligning washing pipe 3, the step on top
The outer diameter of 3-1 is greater than the internal orifice dimension of the lower step of union 1.
There is annular groove 1-2 on the inner wall of union 1 at the upper plane of 1 lower step of union.
The upper surface clear opening 3-5 of the aligning washing pipe 3 is in the first tapered plane 3-2 dodged outward, and lower end surface is in sudden strain of a muscle outward
The second tapered plane 3-3.
When the utility model is specifically used, aligning washing pipe is installed in washing pipe assembly, is installed with tap corresponding position,
Aligning washing pipe lower end passes through the centre bore of union, and the step on the top of aligning washing pipe is placed in the platform of union center bore inner wall lower part
On rank, the step on the top of aligning washing pipe and have annular space between union inner wall, constitute aligning washing pipe in union can
Aligning structure can have suitable eccentric adjustment, aligning washing pipe lower end outer round body convenient for aligning washing pipe in union in centre bore
For a smooth disc, for sealing with sealed packing, aligning washing pipe center can be concentric with tap main body, union and aligning washing pipe
Decentraction is swung, and guarantees sealing ring dynamic sealing during rotation, realizes the quiet of aligning washing pipe upper surface and faucet body
State sealing guarantees the normal use of washing pipe assembly in use.
In conclusion having obtained the guarantee of dynamic sealing since adjustable washing pipe lower end is concentric circles connection, upper end is adjustable
Plane static seal, is also guaranteed, and has preferable sealing effect, extends the service life of washing pipe assembly, preferable to solve
Previous washing pipe assembly service life short phenomenon improves the safety of rig floor operation, easy to install and use, using effect
It is good, extend the service life of washing pipe assembly, economize on resources, improve the safety of drill body operation, economic and social benefit is significant.
