Description
technical field:
The utility model relates to oil equipment technical field, is specifically related to a kind of economic benefits and social benefits blowout-prevention wellhead sealing device.
background technology:
At present, the wellhead polish rod sealing device overwhelming majority of oil extraction in oil field onsite application is rubber packing, not anti-bias, not wear-resisting, service life of equipment is short, also need frequent maintenance, and when oil pumping polish rod ruptures, cause crude oil outer spray in a large number, both have impact on oil yield, there is contaminated environment, existing blowout hookup is all generally utilize spring to be that spray-proof ball uses, when utilizing spring, the frictional force of spray-proof ball and polished rod can be made to become large, spray-proof ball and polished rod can be made to produce huge wearing and tearing, long-term wearing and tearing can make the effect of blowout prevention greatly reduce, in order to solve the problems of the technologies described above, a kind of new technical scheme of special proposition.
utility model content:
The purpose of this utility model is the weak point existed to overcome above-mentioned prior art, and provides a kind of economic benefits and social benefits blowout-prevention wellhead sealing device, and it is easy to use, simple to operate, be easy to large-scale promotion application.
The technical solution adopted in the utility model is: a kind of economic benefits and social benefits blowout-prevention wellhead sealing device, comprise tuningout lower body, backing plate, large gland and packing body, tuningout lower body inside is provided with backing plate, tuningout lower body inside is provided with spray-proof ball, contact with tuningout upper body on the right side of tuningout lower body, tuningout upper body and large gland are threaded connection, inside, tuningout upper body is provided with rubber parts, rubber parts contacts with gland, tuningout upper body and packing body are threaded connection, safetied pin is provided with on the left of packing body, on the right side of packing body, inside is provided with packing gland, packing body right-hand member and anti-sprinkler body are threaded connection, anti-sprinkler body inside is provided with iron core, iron core outer cover has nylon outer shell, nylon outer shell contacts with spray-proof ball gland and spray-proof ball gland and anti-sprinkler body are threaded connection, anti-sprinkler body inside is provided with strong magnet and strong magnet is corresponding with the position of nylon outer shell, strong magnet contacts with magnet gland, magnet gland and anti-sprinkler body are threaded connection, anti-sprinkler body right-hand member and little gland are threaded connection.
The quantity of described safetied pin is no less than two.
The beneficial effects of the utility model are: in the process used, oil pumping polish rod is placed into anti-sprinkler body inner, when oil pumping polish rod ruptures, spray-proof ball can due to the effect of liquid punching press, spray-proof ball is flushed on rubber parts, blocked, crude oil can not be sprayed, the iron core being simultaneously positioned at top can be drawn onto on strong magnet due to the effect of strong magnet, and is blocked by anti-sprinkler body, utilizes strong magnet to attract iron core simultaneously, avoid spring directly to contact, avoid direct wearing and tearing, its expense is reduced greatly, brings great convenience to user.
