Description
Technical field:
The utility model relates to petroleum technology field, is specifically related to the anti-top spray device of a kind of oil well.
Background technology:
At present, having in bar oil recovery process, the polished rod fracture accident at sucker rod top is occurring sometimes.Oil pumper installation foundation is lower, bottom polished rod eye clamping plate from packing box distance compared with little and dead space is large, polished rod broken end will fall into below packing box, deep well pump plunger is sat dead in pump barrel, oil well stops production and well head is in runaway condition, in a large amount of oil wells, oil gas and collector and delivery pipe converge the gas mixture that flows back into and will from well head jet flow out, cause ample resources to waste and large area environment pollution, and the gas mixture of taking measures to prevent oil gas and collector and delivery pipe in oil well from converging in time and flowing back into is from well head jet flow.
Utility model content:
In order to solve the problem, the utility model provides a kind of technical scheme: the anti-top spray device of a kind of oil well, main body is: polished rod, and its innovative point is: also comprise housing, wedge block, end cap, shutoff room, push rod, pushing hands, bearing pin, steel ball, side cover, valve chamber, spool, handle and bearing pin; Be provided with cavity in described housing, described housing is coated on the external surface of polished rod; Described wedge block is fixedly connected on the upper end external surface of polished rod; Described end cap is fixedly connected on the upper surface of housing; Described shutoff room is fixedly connected on housing; Rolling chamber and sliding cavity is provided with in described shutoff room; The rolling chamber of described shutoff room communicates with the cavity of housing; Be provided with steel ball in described rolling chamber, be provided with push rod in described sliding cavity, on described push rod, global formation has pushing hands; Described push rod is provided with through hole, vertical sliding motion is gone back in described shutoff room and is connected with bearing pin; Described valve chamber is fixedly connected on housing in the mode being parallel to horizontal plane; Described spool is slidably connected in the chamber of valve chamber; Described spool is fixedly connected with bearing pin; Described bearing pin is fixedly connected with jug; Described side cover is fixedly connected on the left side of valve chamber.
As preferably, described pushing hands and handle are provided with anti-slip veins.
As preferably, described wedge block is inverted trapezoidal shape.
The beneficial effects of the utility model: its reasonable in design, modern design is unique, simple to operate, easy to use, when inoperative, block steel ball by bearing pin, when leakage, by pull-out handle, bearing pin falls, steel ball enters cavity, intercepts loop, can also press handle, spool is advanced polished rod, and intercept loop, such design both can ensure enough pressure, and these parts are very easily purchased, without the need to special processing, reduce the cost.
