Abstract
The utility model relates to an oil well pump, in particular to an oil well pump with a replaceable valve. The oil well pump with the replaceable valve comprises an outer barrel and a fixed valve ball, wherein the fixed valve ball is arranged on a fixed valve base, a fixed valve outer shell is arranged outside the fixed valve ball and the fixed valve base, the outer barrel is connected with the fixed valve outer shell through a connecting piece, a supporting frame is arranged at the top of the fixed valve outer shell, at least one replaceable valve base is arranged at the upper end of the supporting frame, a replaceable valve protection cover is arranged in the supporting frame, a groove is formed in the periphery of the bottom end of the supporting frame, and a boss which corresponds to the groove in the supporting frame is arranged in the middle of an inner cavity of the connecting piece. The oil well pump with the replaceable valve has the advantages that due to the fact that at least one replaceable valve is arranged, the problem of oil leakage due to the fact that in the prior art, a replaceable valve cannot be perfectly matched with a prior oil well pump can be solved, and the problem is further solved due to the arrangement of the replaceable valve protection cover, a replaceable kerf sieve tube and a replaceable plug in the supporting frame. The oil well pump with the replaceable valve is more reasonable in structure and better in effect.
Description
Technical field
The utility model relates to a kind of oil well pump, is the replaceable oil well pump of a kind of valve more specifically.
Background technique
When recover the oil in the oil field at present, changing the standing valve ball in the oil gas well servicing is a main job content, can't directly change at well head and change valve ball, flow string and oil well pump all could must be changed after the taking-up, therefore workload is big and cumbersome, wastes time and energy inefficiency, increase operating cost, influenced the normal effectively work of oil well.
In order to address the above problem, application number is that 201220076697.7 patent application discloses a kind of valve formula oil well pump that drags for, comprise urceolus, standing valve, standing valve is seated on the standing valve seat, standing valve and standing valve seat outside are equipped with the standing valve shell, urceolus is connected by link with the standing valve shell, it is characterized in that: described standing valve cover top portion is connected with supporting frame, the supporting frame upper end is equipped with can drag for valve seat, can drag on the valve seat to sit to have and to drag for valve ball, can drag for valve seat and be equipped with and to drag for the valve shell with dragging for the valve ball outside, can drag for the valve cover top portion and be connected to replacement head; Described supporting frame bottom periphery has groove, and there is the boss corresponding with groove on the supporting frame at link inner chamber middle part.
When this can drag for the work of valve formula oil well pump, when standing valve body cisco unity malfunction, can drag under the valve body and put into oil well pump, place the standing valve shell upper, groove corresponding matching on link inner chamber middle part boss and the supporting frame replaces operations such as standing valve normally recovers the oil.Do not need during maintenance oil pipe is proposed, reduced operation cost, shortened the activity duration, reduced cost for oil production.But above-mentioned oil well pump in use, standing valve with can drag for valve all easily by solid particle in injected water, reduce the working life that causes dragging for valve, and above-mentioned oil well pump can only be replaced a standing valve, because be interim replacing, meeting occurs dragging for valve and oil well pump can't reach perfect cooperation, defectives such as leakage of oil occur.
Summary of the invention
At above deficiency, the utility model provides a kind of more reasonable structure, the replaceable oil well pump of the valve of better effects if.
The utility model is achieved through the following technical solutions: the replaceable oil well pump of a kind of valve; comprise urceolus and the standing valve ball that is positioned at urceolus inside; the standing valve ball is arranged on the standing valve seat; standing valve ball and standing valve seat are provided with the standing valve shell outward; urceolus is connected by link with the standing valve shell; the standing valve cover top portion is provided with supporting frame; the supporting frame upper end is provided with at least one and replaces valve seat; replace valve seat and be provided with the replacement valve ball; replace valve seat and be provided with replacement valve shell outward with the replacement valve ball; be provided with in the supporting frame and replace the valve safety cover; replacing the valve safety cover is the hemisphere reticular structure; replace the valve safety cover and have the replacement cutting seam sieve tube; replace the cutting seam sieve tube bottom and be connected with the replacement plug; supporting frame bottom periphery has groove, and there is the boss corresponding with groove on the supporting frame at link inner chamber middle part, replaces the valve cover top portion and is connected to replacement head.
The said fixing valve seat has the standing valve safety cover, and described standing valve safety cover is the hemisphere reticular structure, and said fixing valve safety cover has fixedly cutting seam sieve tube, and fixedly the cutting seam sieve tube bottom is connected with fixedly plug.
Above-mentioned replacement valve seat is two, and two distances of replacing between the valve seat are 10-50cm.
More excellent, two distances of replacing between the valve seat are 25cm.
The beneficial effects of the utility model are: replace valve by at least one is set; solved and replaced the problems such as leakage of oil that valve and former oil well pump occur after can't perfect cooperation in the prior art; and replacement valve safety cover is set in supporting frame, replaces cutting seam sieve tube and replaces plug; the problems referred to above have better been solved; structure is more reasonable, better effects if.
