Abstract
The utility model relates to an energy saving device for the oil pumping, and the utility model belongs to the petroleum extraction machinery. A disjointing device 1 is connected with an oil pumping rod 2 through threads. An upper connector is connected with an outer pipe 8 through the threads. A connection body 9 is connected with the other end of the outer pipe through the threads. A lower connecter 12 is connected with the connection body through the threads. The inner part of the pressing cap 11 is connected with the oil pumping rod 2 glidingly. The outer side of the pressing cap 11 is connected with the connection body through the threads. A rubber ring 10 is positioned between the pressing cap and the connection body. The rubber ring 10 is connected with the oil pumping rod glidingly, and a connection pipe 7 is connected with the connection body 9 through the threads. A valve cover 4 is connected with the connection pipe through the threads. A valve seat 6 is positioned between the valve cover and the connection pipe. A valve ball 5 is positioned on the inner part of the valve cover. The utility model has the advantages that the utility model has novel structure, and a group of valves are increased in the oil pipe on the upper side of the oil pumping pump. When the oil pumping rod is lifted to pump the oil, the utility model can save labor and the utility model can be easy.
Description
Technical field
The utility model belongs to petroleum production machinery.
Background technique
At present, when oil well pump is pumped in the down-hole, work as piston stroking upward, the oil in the stratum is extracted in the pump, make descent of piston again, the oil in the pump is entered in the oil pipe through travelling valve.The shortcoming of this structure is, when oil pumping, piston move up and down relatively effort, the merit of consumption is many.
Summary of the invention
The utility model provides a kind of oil pumping economizer, to solve the problem of oil well pump oil pumping effort.The technological scheme that the utility model is taked is: disjointed device 1 is threaded with sucker rod 2, upper connection 3 is threaded with outer tube 8, this outer tube the other end is threaded with connecting body 9, lower contact 12 is threaded with this connecting body, pressure cap 11 inside are slidingly connected with sucker rod 2, the outside is threaded with this connecting body, glue ring 10 is between this pressure cap and connecting body, be slidingly connected with sucker rod, connecting tube 7 is threaded with connecting body 9, valve cover 4 is threaded with this connecting tube, and valve seat 6 is between this valve cover and connecting tube, and valve ball 5 is positioned at the valve cover.During use, when on carry sucker rod, the piston that drives the oil well pump that this sucker rod lower end connects moves upward, oil enters lower contact, enters in the connecting tube jack-up valve ball through the hole of connecting body, the hole of oil on the valve cover entered in the outer tube, move up through upper connection again.
Advantage of the present utility model is: novel structure, in the oil pipe of oil well pump top, increase by one group of valve, when sucker rod drive oil well pump piston is moved downward, oil in the oil pipe is blocked by valve ball, and do not move down with piston, in the oil pipe of the rear portion of piston, can form a vacuum section like this, when at this moment upwards proposing the sucker rod oil pumping, can be more laborsaving and easy.
