Description
Technical field
A kind of structure of the anti-thread gluing of screw thread is the utility model is related to, belongs to the anti-thread gluing technical field of screw thread.
Background technology
The connector of oil field well instrument is threadedly coupled with connecting tube generally use, its connection screw thread generally is stainless steel
Material, since downhole temperature, pressure are all higher, easily occurs Thread-sticking after being used for multiple times at dismounting position.At present, in existing skill
The measure of anti-thread gluing is commonly used in art has the processing of thread surface tufftride, connection screw thread to work as instrument by the way of different hardness etc.
Device length and weight increase to a certain extent when, its Thread-sticking phenomenon is still unavoidable from.Therefore the existing anti-thread gluing of screw thread
Mode or not ideal enough.
Utility model content
The purpose of this utility model is that, there is provided a kind of structure of the anti-thread gluing of screw thread, to solve Thread-sticking, pressure-resistant at the same time
And strength problem, so that overcome the deficiencies in the prior art.
What the technical solution of the utility model was realized in：
A kind of anti-loop fastener structures of screw thread of the utility model, including connector and connecting tube, connector are cylindrical from outside to inside
It is equipped with external screw thread, locating slot and seal groove successively, the external screw thread on connector is threadedly coupled with copper nut, the positioning on connector
Groove is connected with the positioning step on copper nut, is equipped with O-ring in the seal groove on connector, copper nut is equipped with outer spiral shell
Line, the internal thread connection on the external screw thread and connecting tube on copper nut.
In aforementioned structure, the connector and connecting tube are stainless steelwork.
In aforementioned structure, the copper nut is copper alloy product.
By adopting the above-described technical solution, the utility model is compared with prior art, the utility model is in easy thread gluing
Increase wear-resisting swivel nut between threaded connection；Swivel nut endoporus is machined with internal thread, and external screw thread is machined with external cylindrical surface；Swivel nut and company
External screw thread connects on connector, and locking using anaerobic adhesive；Swivel nut external screw thread is connected with connecting tube internal thread, is frequent disassembling part
Position；Swivel nut material is the materials such as high intensity, wear-resisting such as copper alloy.The utility model is suitable for the threaded connection of autoclave appts,
Suitable for the threaded connection of other downhole tools.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：1- connectors, 2-O shapes circle, 3- copper nuts, 4- connecting tubes.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but not as new to this practicality
Any restrictions of type.
The utility model is according to constructed by a kind of method of following anti-thread gluings of screw thread, as shown in Figure 1：This method is
Increase copper nut in one end that connector is connected with connecting tube, external screw thread, the internal thread of copper nut and company are machined with copper nut
The stainless steel external screw thread connection of connector one end, the external screw thread of copper nut are connected with the stainless steel internal thread of connecting tube one end, pass through
The internal thread connection of external screw thread and connecting tube on copper nut；Solves the thread gluing, the pressure-resistant during threaded connection of two stainless steels at the same time
And strength problem.Copper nut is using the Cu alloy material processing that intensity is higher, hardness is softer.Connector is equipped with locating slot, copper
Nut is equipped with positioning step, and positioning step is connected with locating slot, to eliminate influence of the thread pitch to concentricity.Copper spiral shell
When mother is connected with connector, appropriate bonding agent is applied in thread surface, both are bonded as one.Bonding agent uses anaerobic adhesive.Even
Connector is equipped with seal groove, and O-ring is equipped with seal groove.
A kind of structure of the anti-thread gluing of screw thread of the utility model formed according to the above method, as shown in Figure 1：The structure bag
Include connector 1 and connecting tube 4, connector 1 is cylindrical to be equipped with external screw thread, locating slot and seal groove successively from outside to inside, on connector 1
External screw thread be threadedly coupled with copper nut 3, the positioning step on the locating slot on connector 1 and copper nut 3 is connected, connection
Be equipped with O-ring 2 in seal groove on first 1, copper nut 3 is equipped with external screw thread, on the external screw thread and connecting tube 4 on copper nut 3
Internal thread connects.Connector 1 and connecting tube 4 are stainless steelwork.Copper nut 3 is copper alloy product.
Embodiment
As shown in Figure 1, connector 1 and the outer tube that connecting tube 4 is autoclave appts, both are connected this example equipment therefor by screw thread
Connect.Copper nut 3 has positioning step can be with using the processing of copper alloy equal strength is higher, hardness is softer wear-resistant material on copper nut 3
Positioning step coordinates on connector 1, to eliminate influence of the thread pitch to concentricity.Copper nut 3 is connected with connector 1 using screw thread
Connect, apply the bonding agents such as appropriate anaerobic adhesive in thread surface during connection, fixed both with this.Dismount connector 1 and connecting tube 4
When, pervious stainless steel is converted into stainless steel and copper friction with stainless steel friction, reduce the probability of Thread-sticking.
