Abstract
A sealing ring for sealing an oil pumping pipe and a coupling is characterized in that trapezoidal grooves are processed on two ends of the sealing ring respectively, and a groove is processed insidethe sealing ring. When in use of the utility model, the end surface of a ceramic-lined composite oil pipe is extruded into the groove on both sides of the sealing ring to enable the sealing ring to reach the state of slight deformation, and the groove inside the sealing ring is extruded proximately to the state of a plane, thereby achieving the sealing effect.
Description
Technical field
The utility model belongs to production gas technology field, oil field, relates to a kind of seal ring of corrosion-resistant, high temperature resistant, favorable sealing property.
Background technique
The thread seal performance at oil pick-up tube and box cupling place is the important element that influences in the gas production process, and tubing coupling is the important structure part that is used to connect oil pick-up tube in the gas production machinery.At present, most of gas wells use 13Cr oil pipe and box cupling to be tightly connected, and manufacture cost is than higher, though the performance of ceramic liner composite oil pipe and cost all are suitable for the poor sealing performance at the box cupling place than 13Cr oil pipe.
The model utility content
The purpose of this utility model provides a kind of seal ring that is used for corrosion-resistant, high temperature resistant, the favorable sealing property of oil pick-up tube and box cupling place sealing usefulness.
For achieving the above object, the utility model provides the seal ring of a kind of oil pick-up tube and box cupling place sealing usefulness, and it is characterized in that: the seal ring two ends are processed with trapezoidal groove, are processed with groove in the seal ring.
When the utility model used, the ceramic liner composite oil pipe end face was clamp-oned in the groove at seal ring two ends, makes seal ring reach the slight deformation state, the seal ring inner groovy is squeezed the hither plane state, thereby reach sealing effect.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, nitrile rubber elastic sealing ring two ends are processed with trapezoidal groove 1, inside is processed with groove 2, the ceramic liner composite oil pipe end face is clamp-oned in the groove at nitrile rubber elastic sealing ring two ends, make nitrile rubber elastic sealing ring amount of deformation between 1.5-2.5mm, nitrile rubber squeezes the hither plane state with the elastic sealing ring inner groovy, thereby reaches sealing effect, and seal ring corrosion resistance and resistance to high temperature that the nitrile rubber material is made are good.
Claims (1)
1, the seal ring of a kind of oil pick-up tube and box cupling place sealing usefulness, it is characterized in that: the seal ring two ends are processed with trapezoidal groove, are processed with groove in the seal ring.
