Abstract
A new type check valve for polymer injecting pump consists of a plunger piston, a valve-core working cylinder, a valve-core correcting sleeve, a valve-core correcting column, a valve core and a core base. The check valve features that the taper valve core of the original integral structure of check valve and the correcting column is changed to two-body structure of sphere valve core and the correcting column, a sphere valve-core correcting base with an inner conical surface is arranged at the lower part of the sphere valve-core correcting column; the sphere valve core seats on the originally conical sealed valve base, the inner conical surface of the correcting base weighs on the sphere valve core, the correcting column is hitched in the valve-core correcting sleeve, a same spiral spring is hitched between the correcting sleeve and the correcting base.
Description
One, technical field
The utility model relates to the novel one-way valve of using on a kind of polymer-injecting pump (plunger pump) of polymer-injecting pump.
Two, background technique
Development late stage has been arrived in the oil field at present, in order to improve the oil field ultimate recovery, some oil field begins polymer injection for a long time and recovers the oil, in annotating collecting process, polymer-injecting pump (plunger pump) is a key equipment, and the fine or not key of polymer-injecting pump work is an one-way valve, used polymer-injecting pump one-way valve, its spool is a taper valve core, and its valve seat is a conical valve seat.Combination seal by both conical surfaces, its sealing anchor ring is fixed, requirement is linear sealing, in fact owing to the problem of machining accuracy, great majority all are face seal, for spool, its work is to pump, impurity particle is maximum to its impact, corrosion in the polymer, and its sealing anchor ring is given soon and destroyed, and reduces the pump efficiency of polymer-injecting pump.
Three, summary of the invention
The purpose of this utility model provides the novel one-way valve of a kind of polymer-injecting pump, and the seal spool anchor ring that solves above-mentioned prior art existence is fixed, and is very fast by the impact of the impurity particle in the polymers, the bad problem that causes sealability reduction, the reduction of polymer-injecting pump pump efficiency of corrosion.
The technical solution of the utility model realizes in the following manner:
The utility model is set upright post, spool and valve core case by plunger, spool working barrel, spool supporting positive cover, spool and is formed, it is characterized in that with the taper valve core of former one-way valve and set upright two body structures that the post integrative-structure changes spherical valve core into and sets upright post that spherical valve core is set upright the spherical valve core that the post bottom is provided with a band inner conical face and set upright seat; Spherical valve core is sitting on the former cone seal valve seat, and the inner conical surface of setting upright seat is pressed on the spherical valve core, sets upright column sleeve in the spool supporting positive cover, supporting positive cover with set upright between the seat with overlapping a helical spring.
The utility model compared with the prior art, has the unfixed advantage of seal spool line, its potted line is whole spheroid, rotatablely moving and change with ball, and and linear sealing has really been accomplished in the sealing between the sealing seat, improve sealed precision, prolonged the working life of one-way valve, improved the pump efficiency of polymer-injecting pump.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model
1-plunger 2-spool working barrel 3-spool is set upright a 4-spherical valve core 5-valve seat 6-bolt 7-spool and is set upright post 8-helical spring 9-spool supporting positive cover among the figure
Five, embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is set upright seat 3, spherical valve core 4, valve seat 5, bolt 6, spool by plunger 1, spool working barrel 2, spool and is set upright post 7, helical spring 8 and spool supporting positive cover 9 and forms, it is characterized in that changing the taper valve core of former one-way valve and the integrative-structure of setting upright post into two body structures that spherical valve core 4 and spherical valve core are set upright post 7; Spherical valve core is set upright the spherical valve core that post 7 bottoms are provided with a band inner conical face and is set upright seat 3, sets upright post 7 with spherical valve core and is made as one; Spherical valve core 4 is sitting on the former cone seal valve seat 5, the inner conical surface that spherical valve core is set upright seat is pressed on the spherical valve core, spherical valve core is set upright post 7 and is enclosed within the spool supporting positive cover 9, is connected with bolt 6 between the supporting positive cover and setting upright between the seat with helical spring 8 of cover, valve seat 5 and spool working barrel 2.Piston rod is connected with plunger 1.Piston rod drives plunger, the to-and-fro motion in plunger case of spool working barrel, when moving backward, feed liquor in the plunger case, when travelling forward, liquid in the plunger case is opened spherical valve core, set upright tube and plunger cavity discharge from spool, spherical valve core is opened with the to-and-fro motion of plunger and is closed, and polymer is annotated in the oil-feed well stratum.
