Once the oil pipe is lowered into the well, other operations such as oil well washing, oil pipe steam injection, and oil pipe water injection cannot be realized. . The function is single, when other operations are carried out through the oil pipe, the pipe string needs to be re-lifted, which increases the operating cost, delays the production time, and reduces the production time of the pumping unit)

实用新型内容:Utility model content:

本实用新型的目的在于提供一种多用途抽油泵固定阀。采用分体式结构,固定阀总承与泵筒分离,采取下入泵筒后投入固定阀总承的方式,即使是在泵筒下入油井内的情况下,也可以实施通过油管进行洗压井、注汽和注水等作业,减少了作业成本,争取了生产时间,提高了抽油机的生产效率。The purpose of the utility model is to provide a fixed valve for multi-purpose oil well pump. The split structure is adopted, the fixed valve assembly is separated from the pump barrel, and the fixed valve assembly is put into the pump barrel after being lowered. Even when the pump barrel is lowered into the oil well, it is also possible to perform well washing and well pressure through the tubing , steam injection and water injection, etc., which reduces the operating cost, wins the production time, and improves the production efficiency of the pumping unit.

本实用新型是这样实现的,此种多用途抽油泵固定阀由上接头(1)、下接头(9)、固定阀总承构成,固定阀总承包括内套(2)、弹簧(3)、卡块(4)、固定钉(5)、凡尔球(6)、球座(7)、压帽(8),上接头(1)与下接头(9)连接,其内有内套(2),在内套(2)外环形槽上有弹簧(3)连接卡块(4),并有固定钉(5)固定,在内套(2)内有凡尔球(6)座在球座(7)上并有压帽(8)固定,内套(2)的外台阶和下接头(9)的内台阶实现固定阀总承向下限位,卡块(4)在上接头(1)的环形槽内实现固定阀总承上限位,内套(2)的外台阶以下光滑外表面和下接头(9)的光滑内表面过盈配合实现密封。The utility model is realized in this way. The fixed valve of this multipurpose oil well pump is composed of an upper joint (1), a lower joint (9), and a fixed valve assembly. The fixed valve assembly includes an inner sleeve (2), a spring (3) , block (4), fixing nail (5), ball (6), ball seat (7), pressure cap (8), the upper joint (1) is connected with the lower joint (9), and there is an inner sleeve inside (2), there is a spring (3) connected to the block (4) on the outer annular groove of the inner sleeve (2), and it is fixed by a fixing nail (5), and there is a ball (6) seat in the inner sleeve (2) The ball seat (7) is fixed with a pressure cap (8), the outer step of the inner sleeve (2) and the inner step of the lower joint (9) realize the lower limit of the fixed valve assembly, and the clamping block (4) is on the upper joint The upper limit of the fixed valve assembly is realized in the annular groove of (1), and the smooth outer surface below the outer step of the inner sleeve (2) and the smooth inner surface of the lower joint (9) have an interference fit to realize sealing.

工作时,上接头和下接头连接在一起并连接在抽油泵泵筒下端。固定阀总承在下泵筒时不下入井内。这样,泵筒下完之后,整个油管柱内外是连通的,可实现通过油管作业的功能,如注蒸汽、注水、洗压井和冲砂等。当需要抽油泵采油生产时,在油管内将固定阀总承投放井内,同时下抽油泵活塞,在固定阀总承本身重量和抽油泵活塞压力的作用下,固定阀总承进入下接头和上接头组成的圆柱形空腔内,通过内套的外台阶和下接头的内台阶实现固定阀总承向下限位,通过卡块在弹簧弹力的作用下弹出,进入上接头的环形槽内实现固定阀总承上限位,通过内套的外台阶以下经特殊处理的光滑外表面和下接头经特殊处理的光滑内表面过盈配合实现密封,从而实现正常生产。When working, the upper joint and the lower joint are connected together and connected to the lower end of the pump barrel of the oil well pump. The fixed valve assembly does not go down into the well when the pump barrel is lowered. In this way, after the pump barrel is lowered, the inside and outside of the entire tubing string are connected, and the functions of operating through the tubing can be realized, such as steam injection, water injection, washing and killing, and sand washing. When the oil pump is needed for oil production, the fixed valve assembly is put into the well in the oil pipe, and the piston of the oil well pump is lowered at the same time. In the cylindrical cavity formed by the joint, the lower limit of the fixed valve assembly is realized through the outer step of the inner sleeve and the inner step of the lower joint, and the clamping block is ejected under the action of the spring force and enters the annular groove of the upper joint to realize the fixation The upper limit of the valve assembly is sealed through the interference fit between the specially treated smooth outer surface below the outer step of the inner sleeve and the specially treated smooth inner surface of the lower joint, so as to realize normal production.
