Abstract
The utility model relates to an operating device with pressure in an oil field and an oil well, in particular to a twin-stage self-adaption flashboard blowout preventer. The device is characterized in that four flashboard bodies are installed inside a cross body, main hydraulic cylinders are arranged on two sides of the cross body, an adjusting mechanism is connected with the main hydraulic cylinder through a bolt, the adjusting mechanism comprises a double wedge and a small hydraulic cylinder, the main hydraulic cylinder is provided with a pressure balancing mechanism, the distance between the upper flashboard body and the lower flashboard body is larger than the coupling length of an oil pipe, replaceable oil scrapping plates are arranged on the lower portion of the flashboard bodies, a spring adjusting mechanism is arranged inside the adjusting mechanism, and the spring adjusting mechanism controls the flashboard bodies through a guide rod and a piston rod and enables the oil scrapping plates and the oil pipe to be closely contacted. The device is small in occupied space, convenient and flexible to operate, and has an oil scraping function. The device overcomes the defects of being big in the occupied space and inconvenient to operate, and installing an additional oil scrapping machine of the blowout preventer in the prior art.
Description
Technical field:
The utility model relates to a kind of oilfield operation device under pressure, particularly a kind of twin-stage self adaptation ram preventer.
Background technology:
At present, during Operating Pressure, will use at least two half envelope preventer could derive box cupling, the blowout preventer set volume is large, highly high, operation inconvenience, blowout preventer set function singleness simultaneously, do not possess the functional oil of scraping, in order to wipe the crude oil on oil-pipe external wall off, need to increase in addition one to two group of oil wiper.
The utility model content:
The technical problems to be solved in the utility model is to provide a kind of twin-stage self adaptation ram preventer, and this device has realized that volume is little, flexible to operation, has the functional oil of scraping.Overcome existing blowout preventer set volume large, operation is inconvenient, needs to install in addition the deficiency of oil wiper simultaneously.
Technical solution adopted in the utility model is: a kind of twin-stage self adaptation ram preventer comprises the big four body; Four flashboard bodies are housed in the big four body, big four body both sides are equipped with main fluid cylinder, governor motion is connected with main fluid cylinder by bolt, governor motion comprises dual-wedge and small liquid jar, be designed with pressure balance mechanism on main fluid cylinder, distance between upper and lower two flashboard bodies is greater than tubing coupling length, flashboard body bottom is designed with interchangeable oil scraping plate, the spring governor motion is installed in governor motion, and the spring governor motion is controlled the flashboard body by guide rod and piston rod and is made oil scraping plate and oil pipe close contact.
The beneficial effects of the utility model are: the utility model is owing to having adopted the mode that four flashboard bodies are housed in the big four body, thereby has the effect that volume is little, flexible to operation; Be designed with the mode of interchangeable oil scraping plate owing to having adopted in flashboard body bottom, thereby there is the functional oil of scraping, do not need to install in addition oil wiper.
The accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing is structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of twin-stage self adaptation ram preventer, comprise big four body 2; Four flashboard bodies 1 are housed in big four body 2, big four body 2 both sides are equipped with main fluid cylinder 3, governor motion 4 is connected with main fluid cylinder 3 by bolt, governor motion 4 comprises dual-wedge and small liquid jar, be designed with pressure balance mechanism 5 on main fluid cylinder 3, distance between upper and lower two flashboard bodies 1 is greater than tubing coupling length, flashboard body 1 bottom is designed with interchangeable oil scraping plate, the spring governor motion is installed in governor motion 4, and the spring governor motion is controlled flashboard body 1 by guide rod and piston rod and is made oil scraping plate and oil pipe close contact.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model not is limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
