Abstract
The utility model relates to a sealing device of a pumping well, in particular to a wellhead seal applicable to a pumping well. The sealing device of the pumping well comprises a gland 1, an oil pumping polish rod 2, a press sleeve 3, an upper sealing gasket 4, a sealing stuffing box 5, a wellhead 6, a lower sealing gasket 7, sealing stuffing 8, a handle 9 and the like. The sealing device of the pumping well has the advantages that as the upper portion of an inner cavity of the sealing stuffing box is cylindrical while the lower portion of the inner cavity is in the shape of an inclined side plane, after being compacted, owing to elasticity and mobility of sealing stuffing particles or sealing stuffing strips, the sealing stuffing is pushed by the inclined side plane so as to automatically move towards the oil pumping polish rod to be aligned to the center, and eccentric wear is prevented. After the sealing stuffing is worn and used up, only adding of the sealing stuffing is required, and accordingly waste of the sealing stuffing is avoided.
Description
