Connect raised intermeshing, it is described in be fixedly connected with the outer middle side part of projection there are multiple positioning rotation stop grooves, it is described it is outer be fixedly connected it is convex
Playing middle part has positioning rotation stop hole, and the positioning rotation stop hole is corresponding with positioning rotation stop groove, is connected inside the positioning rotation stop hole
Rotation stop screw thread is positioned, the positioning rotation stop screw thread is intermeshed with positioning rotation stop hole, the positioning rotation stop screw thread insertion positioning stops
In turn trough, connection sealing gasket mounting groove on the outside of the positioning rotation stop hole, the sealing gasket mounting groove inside connection sealing gasket is described
On the inside of sealing gasket on the outside of connection positioning rotation stop screw thread.
The upper oil recovery post lower left side has a upper oil recovery column sealing groove, it is described in be fixedly connected convex upper portion have it is outer solid
Determine oil recovery post in connection inner seal ring inside raised seals groove, the outer fixed lobe seal groove, the inner seal ring insertion close
In sealing groove.
It is described outer to be fixedly connected under there is interior fixed lobe seal groove, the lower oil recovery post upper right to have for raised bottom
Fixed lobe is close in connection exterior seal ring inside oil recovery column sealing groove, the lower oil recovery column sealing groove, the exterior seal ring insertion
In sealing groove.
Beneficial effect：
In positioning rotation stop hole, positioning rotation stop groove, position under the mutual cooperation effect of rotation stop screw thread so that be connected through a screw thread
It is outer be fixedly connected it is raised will not be relatively rotated with the interior projection that is fixedly connected, structure more stablize, while in external reinforcing
In the presence of set, inside it is fixedly connected with projection and is fixed support with being fixedly connected outside outside the junction of projection, further increase
The stability of oil recovery post connection, reliable and stable on lower oil recovery post month, and in the common with cooperation of inner seal ring and exterior seal ring
Under so that the joint gap between lower oil recovery post and upper oil recovery post is sealed, be effectively prevented be by leaking,
It is rational in infrastructure, good sealing effect.
Brief description of the drawings
Fig. 1 is novel oilfield flow string structural representation described in the utility model.
Fig. 2 is Fig. 1 described in the utility model partial enlargement figure structure schematic representation.
Embodiment
The utility model is described in further detail below according to drawings and examples：
A kind of novel oilfield flow string, including lower oil recovery post 1, it is interior be fixedly connected with projection 2, it is positioning rotation stop screw thread 8, outer close
