Abstract
The invention relates to a communicated oil inlet valve for an oil-well pump, which consists of a pressure lever, a valve cover, an oil inlet valve ball, an oil inlet valve seat, a mandril and a valve seat joint, wherein the pressure lever is arranged on the upper part of the valve cover; the oil inlet valve ball and the oil inlet valve seat are arranged inside the valve cover; the oil inlet valve ball is positioned under the pressure lever; the mandril is arranged inside the valve seat joint; the mandril passes through the oil inlet valve seat; the upper end of the mandril is positioned under the oil inlet valve ball; the lower part of the valve cover is provided with a sieve tube the upper end face of which supports the lower end face of the mandril; a contact position of an external cylindrical surface of the pressure lever and the valve cover adopts interference fit; the large-diameter position of the mandril is provided with a plurality of upright holes which are crossed with the small-diameter position of the mandril; and the upper end of the mandril is positioned inside the oil inlet valve seat, and the mandril separates the oil inlet valve ball from the oil inlet valve seat and drives the upper part and the lower part of the oil inlet valve seat to be communicated. The communicated oil inlet valve for the oil-well pump can transmit the hydraulic pressure to the lower side of the oil-well pump and can seal a hydraulic packer on the lower part of the oil-well pump, thereby being capable of putting down the hydraulic packer with the pump. When the oil inlet valve is used on an oil field where the hydraulic packer is put down, the operating procedure can be reduced; the operating time can be shortened; and the operating cost can be saved.
Description
One, technical field
The present invention is the oil production equipment of oil field oil recovery usefulness, is the parts on the oil well pump, particularly a kind of unite oil well pump oil valve.
Two, background technique
The oil well pump kind that use in the oil field is more, but the deficiency that all has certain aspect, can not reach certain specific (special) requirements, when needs band pump is realized the hydraulic type packer set, oil well pump commonly used is because under the obstruct of oiling valve, can not in oil pipe on the pump, under pump, inject liquid in the oil pipe, so hydraulic packer can not the seat envelope.As the patent No.: 98208542.7 long-plunger self-releasing type oil well pumps, after long-plunger tripped out pump barrel, the liquid on the pump in the oil pipe can only flow in the sleeve pipe from pump, can not inflow pump under, can not be used in well, injecting the oil well of liquid.Therefore, the oil well of following hydraulic packer all is to adopt first lower packet seat envelope, trips out a tube sealing post then, is lowered to the flow string of band oil well pump again.This method operation is many, and the activity duration is long, the expense height.
Three, summary of the invention
The objective of the invention is to design a kind of unite oil well pump oil valve, during hydraulic packer seat envelope, hydraulic pressure can be reached on the packet under the oil well pump, reduce flow chart, shorten the activity duration, save operating cost.
The object of the present invention is achieved like this: be made up of depression bar, valve bonnet, oil-feed valve ball, oil-feed valve seat, push rod, valve base joint, depression bar is installed in valve bonnet top, oil-feed valve ball, oil-feed valve seat are installed in the valve bonnet, the oil-feed valve ball is under the depression bar, push rod is installed in the valve base joint, push rod passes the oil-feed valve seat, and the push rod upper end is under the oiling valve ball.
Screen casing is installed in the valve bonnet bottom, and the push rod lower end surface is withstood in the screen casing upper-end surface.
Depression bar external cylindrical surface and valve bonnet contact position are interference fit.
Depression bar large-diameter portion position is provided with a plurality of perpendicular shapes hole.
Push rod large-diameter portion position is provided with a plurality of perpendicular shapes hole, and also intersect with push rod path position in perpendicular shape hole.
The invention has the beneficial effects as follows: the push rod upper end is in the oiling valve seat, the oil-feed valve ball is pushed up from the oil-feed valve seat, make oil-feed valve seat UNICOM up and down, hydraulic pressure can be reached under the oil well pump, can make the hydraulic packer seat envelope of oil well pump bottom, therefore, can be with hydraulic packer under the pump, on the oil well of following hydraulic packer, use the present invention, can reduce flow chart, shorten the activity duration, save operating cost.
Four, description of drawings
Accompanying drawing is the erection drawing of the embodiment of the invention.
Five, embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described.
Form by depression bar 1, valve bonnet 2, oil-feed valve ball 3, oil-feed valve seat 4, push rod 5, valve base joint 6, screen casing 7, depression bar 1 is installed in valve bonnet 2 tops, oil-feed valve ball 3, oil-feed valve seat 4 are installed in the valve bonnet 2, oil-feed valve ball 3 is under the depression bar 1, push rod 5 is installed in the valve base joint 6, push rod 5 passes oil-feed valve seat 4, and push rod 5 upper ends are under the oiling valve ball 3.
Screen casing 7 is installed in valve bonnet 2 bottoms, and push rod 5 lower end surfaces are withstood in screen casing 7 upper-end surfaces.
Depression bar 1 external cylindrical surface and valve bonnet 2 contact position are interference fit.
Depression bar 1 large-diameter portion position is provided with a plurality of perpendicular shapes hole.
Push rod 5 large-diameter portion positions are provided with a plurality of perpendicular shapes hole, and also intersect with push rod 5 path positions in perpendicular shape hole.
The present invention is installed under the oil well pump pump barrel, and behind the Hydraulic power tools G.I.H, making oil-feed valve seat 4 is up and down UNICOM, hydraulic pressure can be reached under the oil well pump, makes the Hydraulic power tools action of oil well pump bottom, or injects liquid to the oil well pump bottom.After finishing to oil well pump bottom injection hydraulic work, be lowered to oil pump plunger assembly, when bumping pump, the plunger piston assembly lower end contacts with depression bar 1, the rod weight on plunger piston assembly top is pressed on depression bar, oil-feed valve ball 3, the push rod 5, cuts off push rod 5 lower disk, and the part of oil-feed valve ball 3 and push rod 5 falls, oil-feed valve ball 3 can be located on the oil-feed valve seat 4, the oil well pump work of can normally pumping.Screen casing 7 bottoms are provided with blocking apparatus, and the part of push rod 5 can not fall in the well, can together propose ground with tubing string.
