Abstract
A sand-bury-preventing oil well pump oil inlet valve comprises a pump cylinder connector, a connection cylinder, a valve cover, a valve ball, a valve seat, an oil inlet pipe and a tail pipe connector. An oil outlet groove is arranged in the valve cover, the valve ball and the valve seat are arranged in the valve cover, the valve ball is arranged in a valve seat hole, the upper portion of the oil inlet pipe is connected with the valve cover, the upper end face of the oil inlet pipe abuts against the lower end face of the valve seat, the lower portion of the oil inlet pipe is connected with internal threads of the upper portion of the tail pipe connector, and the lower portion of the pump cylinder connector is connected with the upper portion of the connection cylinder. The lower portion of the connection cylinder is connected with external threads of the upper portion of the tail pipe connector, and a sand storage annular space is formed between the inner diameter of the connection cylinder and the outer diameter of the oil inlet pipe. After sand sinks into the sand storage annular space between the oil inlet pipe and the connection cylinder, the oil inlet valve can not be buried by the sand, an oil inlet channel is unblocked all the time, an oil well is long in production period and can not stop producing, operation of pump starting, pump replacing and pump removing does not need to be carried out frequently, and the sand-bury-preventing oil well pump oil inlet valve has great economical benefits.
Description
Technical field
The utility model belongs to the oil field pumping unit, is the matching parts on the oil well pump, and particularly a kind of sand control buries oil-well pump oil inlet valve.
Background technique
There is not the space between the present oil-well pump oil inlet valve and the piston of oil well pump, when oiling valve top deposits a small amount of sand or foreign material, will bury oiling valve, stop up oil discharge passage, causing can not oil extraction, oil well is stopped production, must will be on the down-hole oil well pump of km and trip out to change to be lowered to again behind the pump oil well is resumed production, thereby cause great through the mistake of damaging due to crushing.
Summary of the invention
The purpose of this utility model is that a kind of sand control of design buries oil-well pump oil inlet valve, and it is not buried by sand, prolongs the oil well production cycle, avoids economic loss.
The purpose of this utility model is achieved in that and comprises pump barrel joint, connecting cylinder, valve bonnet, valve ball, valve seat, oil inlet pipe, tail tube joint, the oil groove of going out is arranged on the valve bonnet, valve ball, valve seat are installed in the valve bonnet, the valve ball seat is on valve seat orifice, oil inlet pipe top is connected with valve bonnet, the lower end surface of valve seat is withstood in the oil inlet pipe upper-end surface, the oil inlet pipe bottom is connected with the internal thread on tail tube joint top, pump barrel joint bottom is connected with connecting cylinder top, the connecting cylinder bottom is connected with the outside thread on tail tube joint top, and the external diameter difference of the internal diameter of connecting cylinder and oil inlet pipe forms storage sand annular space.
The beneficial effects of the utility model are: after sand sank to storage sand annular space between oil inlet pipe and the connecting cylinder, oiling valve can not buried by sand, and oil inlet passage is unimpeded all the time, the oil well production phase is long, do not stop production, do not need frequently to rise pump and change pump operation under the pump, have remarkable economic efficiency.
Description of drawings
Accompanying drawing is the utility model embodiment erection drawing.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As shown in the figure, embodiment of the present utility model is comprised pump barrel joint 1, connecting cylinder 2, valve bonnet 3, valve ball 4, valve seat 5, oil inlet pipe 6, tail tube joint 8, on the valve bonnet 3 oil groove of going out is arranged, valve ball 4, valve seat 5 is installed in the valve bonnet 3,4 of valve balls are on valve seat 5 holes, oil inlet pipe 6 tops are connected with valve bonnet 3, the lower end surface that valve seat 5 is withstood in oil inlet pipe 6 upper-end surfaces, the upper-end surface of valve seat 5 is pressed on the circular bead surface of valve bonnet 3, make and keep sealing between valve seat 5 and the valve bonnet, oil inlet pipe 6 bottoms are connected with the internal thread on tail tube joint 8 tops, pump barrel joint 1 bottom is connected with connecting cylinder 2 tops, and connecting cylinder 2 bottoms are connected with the outside thread on tail tube joint 8 tops, and the external diameter difference of the internal diameter of connecting cylinder 2 and oil inlet pipe 6 forms storage sand annular space 7, sand that deposits and foreign material just fall in this cavity, and sand can not bury valve bonnet and go out oil groove.
The outside thread on pump barrel joint 1 top is connected with pump barrel, and the outside thread of tail tube joint 8 bottoms is generally 2
7/
8The TBG tubing round thread is connected with tail pipe under the pump.
