Double sealed anti air rod pump is a rod pump with anti air lock and anti sand jamming functions. It is based on the rod pump and adds a ring valve device. The ring valve is fitted on the valve stem with a small gap. The frictional force generated between the up and down movement of the valve stem and the ring valve helps the ring valve to open and close quickly. When the pump trips downwards, the annular valve bears the load of the liquid column in the oil pipe, so that the floating valve does not bear the liquid injection load and can quickly open, reducing hydraulic shock, preventing air lock, improving pump efficiency, and extending pump service life. In addition, the annular valve can also block sand particles from falling into the pump barrel, preventing sand from jamming the plunger. The sealing mechanism of the pump adopts a new form of soft and hard sealing combination, which includes both metal sealing and cup sealing, thus improving the reliability of the pump's sealing (fixing and sealing) inside the oil pipe. This pump has a wide range of applications and strong adaptability, and can be well used in high gas oil wells with an oil to gas ratio of less than 420 m3/ton, as well as in low angle wells and sand wells.
