Abstract
The utility model provides a ground one-way valve of an oil well. The ground one-way valve comprises an upper joint, a valve core, a valve seat, a centralizing seat, a valve body and a lower joint, wherein the valve seat is mounted in the valve body, and limited via a circular bead in the valve body; the centralizing seat with an oil inlet channel thereon is mounted below the valve body; the lower joint is arranged below the centralizing seat, with upper end propped to the centralizing seat; the valve seat is pressed by the centralizing seat; the upper part of the lower joint is connected with the valve body by screw threads; the valve core is placed in the valve body, and placed on a valve port at the upper end of the valve seat; a lower centralizing rod of the valve core passes through the centralizing seat; the lower part of the upper joint is connected with the upper part of the valve body by screw threads, and provided with an oil outlet channel; an upper centralizing rod of the valve core passes through the lower part of the upper joint; the valve core is uprightly shifted without inclining because of the centralizing mechanism; the valve core is easy to restore, and has long service life; the extracted liquid cannot be overflowed; the production of the oil well cannot be influenced; the oil well has long production period, great oil output, and obvious economic benefit.
Description
Technical field
The utility model is the equipment that oil field pumping well is used, and is a kind of oil well ground one-way valve.
Background technique
In oilfield, when oil well stopped well for some reason, in the interior extraction liquid of oil pipe can flow backwards Hui Jing on the oil well pump, when pipeline rupture on the oil well pump was missed, the extraction liquid on the oil well pump in the oil pipe also can flow backwards in the Hui Jing.Extraction liquid can flow backwards, and causes production loss on the one hand, also can cause the ground damage layer on the other hand, therefore; Need be at pumping well floor mounted one-way valve, the one-way valve that uses is at present installed as level, the difficulty that resets, working life is short; Need often maintenance, influence oil well production, produce economic loss.
Summary of the invention
The purpose of the utility model is a kind of oil well of design ground one-way valve, makes its long service life, does not influence oil well production.
The purpose of the utility model is achieved in that and comprises upper connection, spool, valve seat, sets upright seat, valve body, lower contact that valve seat is installed in the valve body, and is spacing by the valve inner shoulder; Be to set upright seat under the valve body, setting upright has oil inlet passage on the seat, and setting upright under the seat is lower contact; The lower contact upper-end surface is withstood and is set upright seat, sets upright seat and pushes down valve seat, and lower contact top is threaded with valve body; Lay spool in the valve body, valve core case drops on the valve port of valve seat upper end, and righting rod passes and sets upright seat under the spool; The upper connection bottom is threaded with valve body top, and oil discharge passage is arranged at the upper connection bottom, and righting rod passes the upper connection bottom on the spool.
Suit Returnning spring on the righting rod on the spool, the upper connection lower end surface is withstood in the Returnning spring upper end, and return spring holder is on the spool land face.
The beneficial effect of the utility model is: spool vertically moves, and righting mechanism is arranged, and spool can be not crooked, and spool resets easily; Long service life, extraction liquid can not flow backwards, and does not influence oil well production; The oil well production cycle is long, and oil output is many, has remarkable economic efficiency.
Description of drawings
Fig. 1 is the utility model embodiment's a erection drawing.
Embodiment
Below in conjunction with Fig. 1 the utility model embodiment is described.
Can be known that by figure the embodiment of the utility model comprises upper connection 1, spool 3, valve seat 4, sets upright seat 5, valve body 6, lower contact 7, valve seat 4 is installed in the valve body 6; Valve seat 4 is spacing by valve body 6 inner circular bead, under the valve body 6 is to set upright seat 5, and setting upright on the seat 5 has oil inlet passage; Setting upright under the seat 5 is lower contact 7, and lower contact 7 upper-end surfaces are withstood and set upright seat 5, sets upright seat 5 and pushes down valve seat 4; Lower contact 7 tops are threaded with valve body 6, lay spool 3 in the valve body 6, and spool 3 is located on the valve seat 4 upper end valve ports; 3 times righting rods of spool pass sets upright seat 5; Upper connection 1 bottom is threaded with valve body 6 tops, and oil discharge passage 8 is arranged at upper connection 1 bottom, and righting rod passes upper connection 1 bottom on the spool 3.The further measure of the utility model is a suit Returnning spring 2 on the righting rod on the spool 3, and upper connection 1 lower end surface is withstood in Returnning spring 2 upper ends, and 2 of Returnning springs are used in helping spool 3 to reset on spool 3 circular bead surfaces.
The utility model is installed on the oil well flow line, and the fluid of extraction moves up from lower contact, backs down spool 3 through setting upright the oil inlet passage of seat on 5, flows out to metering station from the bottom oil discharge passage 8 of upper connection 1.
