Abstract

The utility model relates to a filling valve of a pressure transmitting oil well pump, which comprises an outer pipe, a valve bank, an inner sealing body and an outer sealing body. The lower part of the valve bank is connected with the inner sealing body; the lower part of the outer pipe is the outer sealing body; the lower part of an upper joint is connected with the upper part of the outer pipe; the upper part of the valve bank is connected with a suspension joint which is hung on the outer pipe; and a releasing sleeve is arranged above the suspension joint. The upper part of the suspension joint is milled into a strip. The suspension joint has an outer circular conical surface. The cylindrical surface or the circular conical surface of the inner sealing body and the cylindrical bore or the circular conical bore of the outer sealing body are designed to interference fit. No parts are needed to be added to the pump. A specification is applicable to all oil well pumps; the mating is simple; the design of a flow passage is not limited; the flow passage can be increased; a valve ball is big and the utility model can not fail; therefore, when applied to the oil well needing to be filled with liquid, the utility model has large use range and reliable work.

Description

Oil intake valve of oil well pump capable of transferring pressure
One, technical field
The utility model 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 technique
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.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 utility model provides a kind of oil intake valve of oil well pump capable of transferring pressure, is used for injecting in well the pumping well of liquid.
The purpose of this utility model has been achieved in that outer tube, valve group, interior seal, external sealed body, valve group bottom connects with interior seal, the outer tube bottom is the external sealed body, the upper connection bottom connects with outer tube top, 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 cylndrical surface of interior seal or conical surface and external sealed body are designed to interference fit.
The beneficial effects of the utility model are: do not need to drop in pump 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, using scope was big when the utility model was used for injecting the oil well of liquid in well, reliable operation.
Four, description of drawings
Accompanying drawing 1 is the utility model embodiment general structure half sectional view.
Accompanying drawing 2 is outline drawings of part 3 in the accompanying drawing 1.
Five, embodiment
Following elder generation is described further embodiment of the present utility model in conjunction with the accompanying drawings.
Form by upper connection 1, suspension joint 3, outer tube 4, valve group 5, interior seal 6, external sealed body 7, outer tube 4 bottoms are external sealed bodies 7, outer tube 4 can be an one-piece parts with external sealed body 7, also can be integral by two scyewed joint, embodiment of the present utility model is that outer tube 4 bottoms connect with external sealed body 7 tops, valve group 5 bottoms connect with interior seal 6, upper connection 1 bottom connects with outer tube 4 tops, upper 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 upper 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, as shown in Figure 2.Suspension joint 3 has outer conical surface 10, and angle is between 15 °-40 °.The cylndrical surface of interior seal 6 or conical surface 8 are designed to interference fit with the cylindrical hole or the conical bore 9 of external sealed 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 sealed body 7 does not contact, owing between the bar body that mill out on suspension joint 3 tops the slit is arranged, so be up and down that runner is unimpeded, can inject liquid down to pump, make the tool work under the pump, after finishing to oil well pump bottom injection hydraulic work, be lowered to oil pump plunger assembly, when bumping pump, the rod weight on plunger piston assembly 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, makes interior receipts of each bar body of suspension joint, break away from suspension with outer tube 4, discharge cover 2, suspension joint 3, valve group 5, interior seal 6 is to the whereabouts, interior seal 6, in the cylindrical hole or conical bore 9 that external sealed body 7 contact, rod weight are pressed into external sealed body 7 with the cylndrical surface or the conical surface 8 of interior seal 6, make it be assembled into one, the interference fit joint fitting surface plays fixing and seal action.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.
