Abstract
A pressure-transmittable oil well pump filling valve comprises an outer tube, a valve set, an inner sealing body and an outer sealing body. The lower part of the valve set is coupled with the inner sealing body, the lower part of the outer tube is the outer sealing body, the lower part of an upper joint is coupled with the upper part of the outer tube, the upper part of the valve set is coupled with a suspension joint which is hung on the outer tube, and a release sleeve is positioned above the suspension joint. The upper part of the suspension joint is milled into a strip body, and the suspension joint is provided with an outer conical surface. A cylindrical surface or a conical surface of the inner sealing body is designed to be in interference fit with a cylindrical hole or a conical hole of the outer sealing body. Adding components to the pump is unnecessary, one specification can be suitable for various oil well pumps, thus the filling valve has simple assembly and unrestricted design flow passage, the flow passage can be enlarged, and a valve ball is large and can not fail. Therefore, the filling valve has wide application scope and reliable operation when the filling valve is used in an oil well which needs to be injected with liquid.
Description
One, technical field
The invention belongs to the equipment on the downhole pump of oil field, is a kind of oil intake valve of oil well pump capable of transferring pressure.
Two, background technology
Can not in oil pipe on the pump, in well, inject liquid after oil-well pump oil inlet valve commonly used is gone into the well, can not be used in well, to inject the oil well of liquid.One Chinese patent application 02254108.x throwing type oil-well pump oil inlet valve can inject liquid in well, but has two shortcomings: the one, only be applicable to big oil well pump, and if this equipment is installed on little pump, because its valve ball is little, runner is little, poor reliability; The 2nd, specification is many, and a kind of pump is directly joined a kind of specification, supporting trouble.
Three, summary of the invention
The purpose of this invention is to provide a kind of oil intake valve of oil well pump capable of transferring pressure, be used in well, to inject the pumpingh well of liquid.
The objective of the invention is to realize like this: outer tube, valve group, interior seal, external seal body are arranged; Valve group bottom connects with interior seal; The outer tube bottom is the external seal body, and the top connection bottom connects with outer tube top, and valve group top connects suspension joint; Suspension joint is suspended on the outer tube, on the suspension joint is to discharge cover.
Suspension joint top is milled and is split into the bar body, and suspension joint has outer conical surface.
The cylindrical hole or the conical bore of the face of cylinder of interior seal or taper seat and external seal body are designed to interference fit.
The invention has the beneficial effects as follows: need in pump, not drop into parts, a kind of specification can be suitable for whole oil well pumps, and supporting simple, the design runner is unrestricted, and runner can strengthen, and valve ball is big, can be not malfunctioning.Therefore, the scope of application was big when the present invention was used in well, injecting the oil well of liquid, reliable operation.
Four, description of drawings
Accompanying drawing 1 is an embodiment of the invention general structure half sectional view.
Accompanying drawing 2 is outline drawings of part 3 in the accompanying drawing 1.
Five, the specific embodiment
Combine accompanying drawing that embodiments of the invention are described further below earlier.
Form by top connection 1, suspension joint 3, outer tube 4, valve group 5, interior seal 6, external seal body 7; Outer tube 4 bottoms are external seal bodies 7; Outer tube 4 can be an one-piece parts with external seal body 7, also can be integral by two thread connection, and embodiments of the invention are that outer tube 4 bottoms connect with external seal body 7 tops; Valve group 5 bottoms connect with interior seal 6; Top connection 1 bottom connects with outer tube 4 tops, and top connection 1 can be the oil well pump pump barrel, also can be the connected component between oil well pump pump barrel and the outer tube 4.Discharge cover 2 and be in the top connection 1 (oil well pump pump barrel), valve group 5 tops connect suspension joint 3, and suspension joint 3 is suspended on the outer tube 4, on the suspension joint 3 are to discharge cover 2, and discharging cover 2 can be the oil pump plunger piston bottom, also can be an independent part.Suspension joint 3 tops are milled and are split into the bar body, shown in accompanying drawing 2.Suspension joint 3 has outer conical surface 10, and angle is between 15 °-40 °.The face of cylinder of interior seal 6 or taper seat 8 are designed to interference fit with the cylindrical hole or the conical bore 9 of external seal body 7.
Be connected in when going into the well under the oil well pump pump barrel, replace existing oil-well pump oil inlet valve, interior seal 6, external seal body 7 do not contact; Owing between the bar body that mill out on suspension joint 3 tops the slit is arranged,, can inject liquid down to pump so be up and down that runner is unimpeded; Make the tool work under the pump, after injecting the hydraulic completion, be lowered to oil pump plunger assembly to the oil well pump bottom; When bumping pump, the rod weight on assembly for plunger top is pressed in and discharges on the cover 2, and interior (circular cone) hole that discharges cover 2 contacts with the outer conical surface of suspension joint 3; Make in each bar body of suspension joint and receive, break away from the suspension with outer tube 4, discharge cover 2, suspension joint 3, valve group 5, interior seal 6 to the whereabouts; Interior seal 6,7 contacts of external seal body; In the cylindrical hole or conical bore 9 that rod weight is pressed into external seal body 7 with the face of cylinder or the taper seat 8 of interior seal 6, make it be assembled into one, the interference fit joint fitting face plays fixing and sealing function.Oil pump plunger assembly bumps the work of can normally pumping of the intact back of pump oil well pump.
Valve group 5 can connect 2 the cover, also can be a cover, determine by hole condition.
Suspension joint 3 falls after also can suspension face being cut off by rod weight.
