Gap.The wedge-type sealer is arranged in sleeve pipe (pit shaft), and cone of the ring packing wedge under pressure along centre is descending, more wedge
It is tighter, realize sealing oil sets annular space purpose.When needed, by beating high pressure or upper lifting pipe post in sleeve pipe (pit shaft) simultaneously
Make ring packing wedge depart from centrum to fall into appearance wedge connecting tube and fail.
But in use, (in the case where no liquid is moistened, flexible gland made of rubber has powerful suction to cone
Attached effect, ring packing wedge is caused to be slided in cone).
In addition, the nylon outer barrel and flexible gland of ring packing wedge are led in use there is also situation about being disengaged from
The problem of effect should be had by causing ring packing wedge to lose.
The content of the invention
In view of this, the utility model is directed to a kind of from profit run-resistant wedge-type sealer, and thread-off proof ring-shaped sealing
Wedge, to solve above-mentioned technical problem.
What the technical solution of the utility model was realized in：
It is a kind of to be arranged with ring packing wedge from profit run-resistant wedge-type sealer, including cone, cone, at one section of cone
Outer surface, which is machined with, holds oil groove section, fills lubricating oil holding in oil groove, plays and acted on from profit, flexible made of rubber so as to eliminate
Powerful absorption affinity of the sealing shroud to cone.
Preferably, the cone length for being machined with appearance oil groove section accounts for 2/3rds of cone total length；
Preferably, the conical section for being machined with appearance oil groove section originates in the upper end of cone.
The appearance oil groove section is mainly made up of a plurality of endless groove, or is made up of a screw type helicla flute.
Ring packing wedge of the present utility model is thread-off proof ring-shaped wedged seal, and it includes flexible gland and nylon outer barrel, Buddhist nun
Imperial outer barrel is placed on flexible gland；Also include clamp ring；Clamp ring is made up of flexible rubber, the preferred fluorine rubber of material
Glue, or hydrogenation nitrile rubber；
The inner surface processing anticreep groove section on the top of the nylon outer barrel, the lock for accommodating clamp ring is used in outer Surface Machining
Collar neck；Clamp ring is then placed in clamp ring neck.
Relative to prior art, the utility model has the advantage that：
Lubricating oil is filled in the appearance oil groove of cone, plays and is acted on from profit, so as to ensure in the case where no liquid is moistened
Flexible gland made of rubber is eliminated to the powerful absorption affinity of cone, enable ring packing wedge in cone slidably；
Under the tightening force effect of clamp ring, on the one hand by the gap banding on the top of nylon outer barrel, on the other hand with nylon outer barrel
The anticreep groove collective effect on surface, anticreep groove bite flexible gland outer wall, and dual guarantee nylon outer barrel and flexible gland are not
Depart from.
Brief description of the drawings
Form a part of accompanying drawing of the present utility model to be used for providing further understanding to of the present utility model, this practicality is new
The schematic description and description of type is used to explain the utility model, does not form to improper restriction of the present utility model.
In accompanying drawing：
Fig. 1 is the state diagram of going into the well of the wedge-type sealer of earlier application；
Fig. 2 be improve after cone broken section and for show open up thereon appearance oil groove close-up schematic view.
Fig. 3 is the ring packing wedge structural representation after improving；
Fig. 4 is the structural representation of clamp ring 83, wherein, lower section is its main view, and top is the section view along axle center；
Fig. 5 is the structural representation of the nylon outer barrel after improving.
Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
The scheme of the application is on the basis of " the wedge-type sealer " disclosed by earlier application CN201510752598.4
Further improve, to save length, the structure and content of " wedge-type sealer " in earlier application do not repeat herein, and because
