Description
Technical field
The utility model is related to the technical field of oil-pumping well head equipment, and in particular to a kind of anti-pollution full work(of portable blowout prevention
Can oil-pumping well head equipment.
Background technology
In the market substantially using the oil pumping polish rod blowout prevention rubber valve of simple function, this valve function is single.Mesh
The packing box through type space sealing part short life that preceding in the market is used, ordinary life is not easy to more at three months or so, not only
Change, and there is no automatic blowout-prevention function；The oil-pumping well head equipment of in the market is very common, and security performance is poor, once occur
Sealing part abrasion or disconnected take off of oil pumping polish rod just easily cause the accidents such as leakage to occur, and can not only cause larger economic waste,
Environmental pollution is more importantly caused, and is difficult to repairing environment, state's laws laws and regulations requirement is not met.
The content of the invention
The purpose of this utility model is：Overcoming the deficiencies in the prior art, there is provided a kind of anti-pollution full work(of portable blowout prevention
Energy oil-pumping well head equipment, by the chute of truncated cone-shaped structure and the sealing shroud matched with chute, when the inner wall abrasion of sealing shroud
After consumption, screwed by thread bush B, so that sleeve pipe B drives cannula C is pushed into sealing shroud, so that the internal diameter of sealing shroud is received
Tightly, so as to still be able to ensure the sealing function of sealing shroud, the service life of sealing shroud is extended；Due to sealing ring B effect, when
When sealing shroud weares and teares, oil can not spray from sleeve pipe B top, so as to will not be polluted to the environment of mouth of pumped oil well；
Due to sealing ring B effect, when sealing shroud weares and teares, oil can not spray from sleeve pipe B top, then be entered by through hole A
Enter in annular chamber, when the oil liquid level in annular chamber reaches through hole B height, oil is overflowed by through hole B, so that oil
Spilling, and the oil pressure reduction after the larger annular chamber in space can be oriented, is easy to collect, further prevents oil pumping
The environment of well head is polluted；, it is necessary to be changed to sealing shroud when sealing is set to operating limit, thread bush B is revolved
Pine, the part in sleeve pipe B and cannula C and sleeve pipe B is removed from oil pumping polish rod, it is downward to its that sealing shroud loses cannula C
Active force after, popped up under helical spring A active force, consequently facilitating operative employee will use the sealing shroud of the limit
