Abstract
The utility model relates to an oil well sealing device, and particularly relates to wellhead seal of a pumping well. The oil well sealing device comprises a gland 1, a pressing sleeve 2, an oil pumping polish rod 3, a seal volume 4, an elastic sleeve 5, a handle 6, a seal box 7, and a wellhead 8 and the like. The oil well sealing device has the advantages that due to the fact that the seal volume is in the sheet shape, the seal volume can tightly cover the oil pumping polish rod under push of the elastic sleeve. Because the elastic sleeve has certain elasticity, the seal volume can automatically move to the oil pumping polish rod and aim at the center. Therefore, good sealing effect is achieved.
Description
Technical field
The utility model relates to a kind of oil well sealing device, especially is applicable to the wellhead sealing of pumpingh well.
Background technology
The well mouth sealing device of present employed pumpingh well, the inner chamber of general sealed stuffing box is cylindrical, airtight and watertight padding is round sheet, because airtight and watertight padding can not be to the oil pumping polish rod automatic centering, so cause leakage of oil behind the airtight and watertight padding eccentric wear, and airtight and watertight padding need integral replacing, cause the waste of material.
Summary of the invention
The purpose of this utility model is to design and a kind ofly can makes airtight and watertight padding to the oil pumping polish rod automatic centering, and airtight and watertight padding is drum, changes easily the oil well sealing device of airtight and watertight padding.
The utility model comprises gland 1, gland 2, oil pumping polish rod 3, sealing volume 4, resilient sleeve 5, handle 6, seal box 7 and well head 8 etc.There is circular hole at the center of gland 1, so that oil pumping polish rod 3 passes through, there is screw thread the inboard of gland 1, and there is handle 6 in the outside, and handle 6 is used for tightening gland 1.Gland 2 is cylindrical, and there is circular hole at its center, so that oil pumping polish rod 3 passes through, cylindrical boss is arranged at its top, so that gland 2 is from the inner chamber taking-up of seal box 7.The outside of seal box 7 is cylindrical, outer upper has screw thread, match with the inside thread of gland 1, the inner chamber of seal box 7 is cylindrical, there is circular hole in the bottom centre of inner chamber, so that oil pumping polish rod 3 passes through, the lower inside of seal box 7 has screw thread, there is screw thread in the outside, upper end of well head 8, matches with the inside thread of seal box 7.The inner chamber of seal box 7 is equipped with resilient sleeve 5, and resilient sleeve 5 is tubulose, and sealing volume 4 is equipped with in resilient sleeve 5 inboards, and sealing volume 4 be sheet, and an end of sealing volume 4 be dull and stereotyped, and the flat board of sealing volume 4 is installed in the top of resilient sleeve 5, rolls up play about in the of 4 to prevent from sealing.
This oil well sealing device, first seal box 7 is installed on the well head 8 in use, then sealing volume 4 is installed between resilient sleeve 5 and the oil pumping polish rod 3, to seal again pack into the inner chamber of seal box 7 of volume 4 and resilient sleeve 5, with pack into the inner chamber top of seal box 7 of gland 2, at last gland 1 is contained on the seal box 7, with handle 6 gland 1 is tightened, just can use.
The utility model has the advantage of this oil well sealing device, because the sealing volume is sheet, under the pushing of resilient sleeve, can closely encase oil pumping polish rod, because resilient sleeve has certain elasticity, the sealing volume can move centring from the trend oil pumping polish rod, plays good sealing function.
