The centralizer is an oil production tool used in oilfield pumping machine wells, and is a new type of product that can improve the pumping efficiency of the pump; It adopts the automatic opening and closing structure of the sliding valve, connected to the sucker rod, when the sucker rod travels down, the slide valve goes up to open the oil passage on the righting body, and when the sucker rod travels up, the slide valve goes down to close the oil passage on the righting body. Therefore, by lifting the liquid column in sections, the load of the sucker rod and the pump load are reduced in sections, the pump leakage is reduced, the elastic elongation deformation of the sucker rod is reduced, and the stroke loss is reduced, so as to improve the effective stroke of the pumping pump, increase the liquid filling capacity of the pump barrel, and improve the pump efficiency.
