Abstract
The utility model relates to an oil pumping well W flow type deep well pump fixed valve uniflow valve, which solves the problems that an existing uniflow valve can generate sand deposition and wax deposition easily, and well-flushing is not complete in the production process, the oil pumping well W flow type deep well pump fixed valve uniflow valve comprises a valve cover and a valve ball seat, wherein a valve ball is installed on the valve ball seat, the valve ball seat is installed on an oil inlet pore passage, a circulating cavity is arranged between the valve cover and the valve ball seat, corners on four walls of the circulating cavity are in circular arc shapes, the inner wall is smooth, and a spiral shaped screwed-in type oil inlet pore passage is connected with a bellmouthing type oil inlet guiding inlet. The utility model adopts the structure, changes straight-through type liquid supply of an existing old type uniform valve into rotating liquid supply, the liquid is rotated inwards for forming W-ring shaped water flow, the leakage caused by untight valve ball seat due to sand deposition and wax deposition can be greatly lowered, the oil pumping efficiency of an oil pumping well can be improved, the oil well yield can be increased, the energy can be saved, and the consumption can be lowered.
Description
Technical field
The utility model relates to a kind of pumping well deep-well pump standing valve one-way valve.
Background technique
At present, existing pumping well deep-well pump adopts straight-through type to go into the liquid mode with the standing valve one-way valve, annular space between valve cover and the valve ball seat is made coarse, the inwall turning is a right angle type, the blocking phenomenon that the long-pending sand of easy in process of production appearance, wax deposition cause, thereby cause well-flushing not thorough, influence well-flushing efficient.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provides a kind of long-pending sand, wax deposition phenomenon, pumping well W streaming deep-well pump standing valve one-way valve that well-flushing is thorough, efficient is high effectively avoided; Goal of the invention of the present utility model is achieved through the following technical solutions: a kind of pumping well W streaming deep-well pump standing valve one-way valve, comprise the valve cover, the valve ball seat, valve ball is installed on the valve ball seat, the valve ball seat is installed on the oil-feed duct, be the circulation chamber between valve cover and the valve ball seat, valve cover top is provided with liquid outlet opening, liquid outlet opening communicates with the circulation chamber, the oil-feed duct is connected with horn mouth formula oil-feed introducing port, valve cover and horn mouth formula oil-feed introducing port are respectively with last, following pipe wire snapping hoop connects, it is characterized in that: wall turning, described circulation chamber is circular-arc, inner wall smooth, and the oil-feed duct is helical screw-in oil-feed duct.
The beneficial effects of the utility model: the utility model adopts said structure, before liquid passes through valve ball, at first enter helical screw-in oil-feed duct, to enter liquid utilizes inscribe to revolve and go into, revolve to circumscribed, the straight-through type feed liquor of old-fashioned one-way valve in the past changed into be rotated into liquid, when liquid enters in the circulation chamber, because the circulation cavity wall is smooth, the wall turning is circular-arc, reduce the sand wax deposit, liquid in rotation and go into to form the W annular water flow, reduced sand significantly, the valve ball seat that wax deposit brought is not closed completely and the leakage that produces, improve pumping well oil pumping pump efficiency, increase oil well output, energy-saving and cost-reducing, when using the utility model to the pumping well hot clean-up well, when carwash improved discharge capacity and temperature, the oil well pump feed liquor speeded up, when the high speed flushing fluid passes through helical screw-in oil-feed duct, the rotational speed of liquid is accelerated, and scouring force strengthens, and has and takes husky function, improve hot clean-up well efficient, prolong pumping well operation pump detection period, reduce well maintenance workover eration expense, reduce cost of crude oil production.
