Abstract
The utility model belongs to an oil well mouth sealer, in particular to a polished rod protecting wear-resistant blowout control well mouth sealing device capable of preventing a polished rod from being worn and preventing a well mouth from blowing oil. The polished rod protecting wear-resistant blowout control well mouth sealing device consists of a polished rod protective cover, a connecting base, a nut, a ball head box, a primary packing, a dual-adjustment sleeve, a sealing box, a secondary packing, a polished rod sealing part, a connecting sleeve and a fixing square clamp, and is characterized in that the polished rod protective cover is plated with chrome, the connecting sleeve is arranged at the upper end of the polished rod protective cover, the polished rod sealing part is arranged inside the connecting sleeve, the upper end of the connecting sleeve is connected with the fixing square clamp, the polished rod moves up and down to drive the fixing square clamp during production of a pumping well, the fixing square clamp drives the connecting sleeve and the polished rod sheath to move, the polished rod protective cover is plated with chrome, then the polished rod protective cover has high smoothness and can be worn with the primary packing and the secondary packing for a long time, and when the polished rod is broken and loosened, the polished rod sealing part in the connecting sleeve is sealed with the polished rod to prevent spraying oil. The polished rod protecting wear-resistant blowout control well mouth sealing device has the advantages of simple structure, easy operation, fine wear-resistant and blowout control effect, safety, environmental protection and capacity of reducing labor intensity.
Description
Technical field
The utility model belongs to the well mouth of oil well sealer, can prevent that especially a kind of polished rod of the anti-well head oil spout of polished rod wearing and tearing from protecting wear-resistant Blowout prevention wellhead sealing device.
Background technology
At present, what each elephant well mouth of oil well sealer of China adopted is the wellhead sealing device that does not have the polished rod sheath entirely, this wellhead sealing device does not reach the effect of wear-resisting blowout prevention, rise at polished rod under the situation of thorn, the leakage of oil of wellhead sealing device serious wear, in case the disconnected wellhead sealing device oil spout contaminated environment of taking off of polished rod strengthens labour intensity.
Summary of the invention
In order to overcome the problems referred to above; the utility model provides a kind of polished rod to protect wear-resistant Blowout prevention wellhead sealing device; this polished rod is protected wear-resistant Blowout prevention wellhead sealing device; in one-level packing secondary packing, the polished rod sheath is housed; the polished rod sheath has chromium plating outward; there is adapter sleeve the upper end of polished rod sheath; polished rod seal spare is arranged in the adapter sleeve; the upper end of adapter sleeve and fixing square card connection, polished rod moved up and down and drives fixing side card when pumpingh well was produced, and be dynamically connected cover and polished rod sheath of fixing square cassette tape moves; the polished rod sheath has chromium plating highly polished; lasting with the wearing and tearing of one-level packing secondary packing, polished rod breaks when taking off, and prevents oil spout by polished rod seal spare in the adapter sleeve and polished rod seal.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of polished rod protects wear-resistant Blowout prevention wellhead sealing device by the polished rod sheath; Connection Block; nut; the bulb box; the one-level packing; two regulating sleeves; seal box; the secondary packing; polished rod seal spare; adapter sleeve; fixing side card is formed; its special character is: the polished rod sheath has chromium plating outward; there is adapter sleeve the upper end of polished rod sheath; polished rod seal spare is arranged in the adapter sleeve; the upper end of adapter sleeve and fixing square card connection; polished rod moved up and down and drives fixing side card when pumpingh well was produced; be dynamically connected cover and polished rod sheath of fixing square cassette tape moves; the polished rod sheath has chromium plating highly polished; lasting with the wearing and tearing of one-level packing secondary packing; polished rod breaks when taking off, and prevents oil spout by polished rod seal spare in the adapter sleeve and polished rod seal.
The beneficial effects of the utility model are: simple in structure, easy to operate, wear-resisting blowout prevention is effective, and safety and environmental protection reduces labour intensity.
