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, side room, end cap, steel ball, spring, adapter sleeve, holder, bearing pin, support and lifting motor; Described wedge block is two, is separately positioned on the outer round surface of the upper and lower end of polished rod; Described housing is coated on the outer round surface of polished rod; Described side room is fixedly connected on the outside of polished rod center; End cap is fixedly connected with on the right side of described side room; Described steel ball is arranged in the chamber in side room; Spring is provided with between described steel ball and end cap; Described adapter sleeve is vertically set on the upper end in side room; Described holder is fixedly connected on the upper surface of adapter sleeve; Described pin slide is connected in the through hole preset in the middle of adapter sleeve and holder; Described lifting motor is fixedly connected on end cap upper surface; Support is connected with between the output shaft of described lifting motor and bearing pin.
As preferably, described spring is disk spring.
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 lifting motor, support is lifted, thus take up bearing pin, steel ball ejects under the action of the spring, 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.
