Abstract
The utility model relates to an oil well adopting well top theft proof triple valve, comprising a tee, a plug, a valve ball, a ball cover, a valve base, a spring bin, a spring base and coil springs. The utility model is characterized in that one end of the tee horizontal direction is provided with a male thread or a hoop and connects the outlet of an oil extraction tree, and the other end is welded with the reducer valve base; the big diameter end is provided with the plug which is connected with the thread and the ball cover with small holes is welded on the big diameter ring shaped terrace; the small diameter end is provided with the spring bin which is connected with the thread and the valve ball sealing base is embedded on the small diameter ring shaped terrace and the valve ball is arranged between the valve ball sealing base and the spring base; one end of the tee vertical direction is connected with an oil collecting line. The utility model replaces the oil mouth cover, can prevent the oil stealing of outlaws and does not influence the normal well cleaning or well pressing.
Description
One, technical field
The utility model relates to the antitheft three-way valve of the well mouth of oil well of using in a kind of oil field.
Two, background technique
At present, the chance that oil nozzle cover on the production tree steals oil for the lawless person, the lawless person lays down the plug that oil nozzle puts, just can be easily install to crude oil on the car or put into plastic bag and transport to the crude oil place that disposes of stolen goods, change to the banknote of handle greatly, every year, tens0000 tons of crude oil were lost in the oil field herein, caused great economic loss to country.
Three, summary of the invention
The purpose of this utility model provides the antitheft three-way valve of a kind of well mouth of oil well, replaces the oil nozzle cover with this valve, solves the problem that the lawless person utilizes the oil nozzle cover to steal oil.
The technical solution of the utility model realizes in the following manner:
The utility model is by threeway, plug, valve ball, ball cover, valve seat, the spring bucket, spring seat and helical spring are formed, a horizontal end that it is characterized in that threeway is provided with male thread or clip head, be connected with the production tree outlet, the other end is welded with the reducing valve seat, an end big at diameter is provided with the plug that is threaded with it, on large diameter ring-shaped step, be welded with narrow meshed ball cover, end at minor diameter is provided with the spring bucket that is threaded with it, the all sides of spring bucket have several rectangular openings, in the spring bucket helical spring is housed, the upper end of spring is provided with spring seat, on the ring-shaped step of minor diameter, be inlaid with the valve ball sealing seat, be provided with valve ball between valve ball sealing seat and spring seat, a vertical end of threeway is connected with gathering line.
The utility model has replaced the oil nozzle cover, has both prevented that the lawless person from stealing oil, do not influence normal well-flushing or kill-job again.

Five, embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is by plug 1, valve seat 2, ball cover 3, valve ball 4, threeway 5, helical spring 6, spring seat 7 and spring bucket 8 are formed, a horizontal end that it is characterized in that threeway 5 is provided with male thread or clip head, be connected with the production tree outlet, the other end is welded with reducing valve seat 2, be provided with the plug 1 that is threaded with it at the big end of diameter, on large diameter ring-shaped step, be welded with narrow meshed ball cover 3, be provided with spring bucket 8 that is threaded with it at an end of minor diameter, the all sides of spring bucket have several rectangular openings, helical spring 6 is housed in the spring bucket, the upper end of spring is provided with spring seat 7, on the ring-shaped step of minor diameter, be inlaid with the valve ball sealing seat, be provided with valve ball 4 between valve ball sealing seat and spring seat, a vertical end of threeway is connected with gathering line.
After the utility model at first connects with production tree and gathering line when using, opening pumping unit normally pumps, oil enters gathering line, when the lawless person dismantled plug and steals oil, oil is being kept off by valve ball to be put to come out, when the lawless person wants to back down valve ball, ball cover is keeping off and pushing up not open, the lawless person can't steal oil, when the oil well well workover, well-flushing, kill-job or when taking other to increase oily measure can be unloaded plug and connect and go up the construction pipeline, can in oil pipe, buy flushing fluid or well-killing liquid with cementing truck, liquid backs down valve ball, enters threeway by all side rectangular openings of spring bucket or circular hole and enters oil pipe again, as well-flushing, flushing fluid returns ground from sleeve pipe and sleeve gate, if kill-job has been bought well-killing liquid and has been got final product, in work progress, the back pressure gate of oil pipeline is closing, strata pressure is high the spray phenomenon can not occur returning more yet, is keeping off because of valve ball is arranged, and can not reflux.
