Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of well mouth of oil well anti-oil leakage device.
In figure, 1. female thread, 2. well head pedestal, 3. topping up rubber ring, 4. abrasive rubber set, 5. rubber slab
B, 6. rubber slab A, 7. topping up rubber ring cover plate, 8. cover spring, 9. well head capping, the most smooth rod aperture.
Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
This utility model provides a kind of well mouth of oil well anti-oil leakage device, as it is shown in figure 1, include tubulose
Well head pedestal 2, well head pedestal 2 inner surface is coaxially connected with annulus, in well head pedestal 2 below annulus
Surface configuration has female thread 1, and in well head pedestal 2, annulus upper section is provided with topping up rubber ring 3, fills
Topping up rubber ring cover plate 7, cover spring 8 and well head capping 9, well it is connected with in turn on liquid rubber ring 3
Being provided with light rod aperture 10 in mouth capping 9, well head capping 9 is connected with well head pedestal 2, topping up rubber ring 3
It is embedded in the abrasive rubber set 4 of the tubulose combined, the internal diameter of abrasive rubber set 4 and the external diameter of polished rod
Identical, abrasive rubber set 4 includes the rubber slab A6 of rectangle and the rubber slab B5 of rectangle, rubber slab A6
It is arranged at intervals with groove A and projection A, two relative for rubber slab B5 sides on two relative sides
On be arranged at intervals with groove B and projection B, groove A and projection A and lay respectively at projection B and groove B
In；
Well head capping 9 is threaded connection with well head pedestal 2；
Rubber slab A6 and the length of rubber slab B5, width and thickness are the most equal；
Gap is arranged at the bottom of groove A and the top of projection B, the top of projection A and the bottom of groove B
There is gap.
The operation principle of this utility model a kind of well mouth of oil well anti-oil leakage device is: by female thread 1 by well
Mouth pedestal 2 is connected with oil pipe, and polished rod sequentially passes through out the light well head capping 9 bottom well head pedestal 2
Rod aperture 10, well head capping 9 is by being compressed cover spring 8, and cover spring 8 is by active force effect
In topping up rubber ring cover plate 7, topping up rubber ring cover plate 7 applies active force, topping up to topping up rubber ring 3
Well head pedestal 2 upper inside surface and abrasive rubber will be overlapped the outer surface of 4 by liquid in rubber ring 3 respectively
Applying active force, abrasive rubber set 4 is under the active force of topping up rubber ring 3, by abrasive rubber set 4
Polished rod be clamped；When the polished rod of attachment crude oil runs up, when overlapping 4 by abrasive rubber, wear-resisting
The crude oil adhered on polished rod, under the active force of topping up rubber ring 3, is scraped in oil return pipe by rubber sleeve 4；When
When well head exists the situation of eccentric wear, abrasive rubber will be overlapped 4 a direction and apply active force, topping up by polished rod
Rubber ring 3 is by arriving to the pressure of abrasive rubber ring 4, and in topping up rubber ring 3 ring, pressure increases, logical
Crossing liquid transfer in topping up rubber ring 3 ring, topping up rubber ring 3 will overlap 4 equidirectionals to abrasive rubber to be executed
Add same purpose power, all the time by active force fixing for abrasive rubber set 4 applying；When abrasive rubber set 4 exists
Under the friction for a long time of polished rod, produce abrasion, under the pressure of topping up rubber ring 3, the end of groove A
The gap at the top of portion and projection B reduces, and the gap of the top of projection A and the bottom of groove B reduces,
Make abrasive rubber set 4 all the time polished rod be kept certain active force, reach the crude oil that will be attached on polished rod
Scrape in oil return pipe.
A kind of well mouth of oil well anti-oil leakage device of the present utility model by arranging topping up rubber ring 3, topping up rubber
