Description
Technical field：
The utility model belongs to technical field of oil extraction equipment, and in particular to a kind of airlock-resistant oil pump.
Background technology：
With the increase of oil field development time, the energy on stratum is constantly consumed, and makes the effect by natural energy crude oil extraction
Fruit is worse and worse, it has to manually increases stratum energy and carrys out crude oil extraction, wherein traditional nitrogen injection, carbon dioxide injection and in recent years
Thick oil filling air catalytic oxidation oil recovery technique to develop is more satisfactory so that its range of application is got in oil recovery effect of field application
Come bigger.But it is more and more obvious that its negative interaction is also showed, especially with continuing to increase for gas injection (vapour) amount so that gas (vapour)
Body affects increasing to the pumping efficiency of oil well pump, the phenomenon of gas lock often occurs in oil pumping process, due to gas in pump barrel
The presence of body, causes in down stroke, and the travelling valve of oil well pump bottom can produce the phenomenon of Time Delay Opening, has had a strong impact on oil pumping
The operating efficiency of pump.Further, since the fluid amount of oil well pump output is very big so that in bottom dead centre and top dead-centre in oil pumping pump work
During conversion, the shock loading acted on sucker rod is larger so that sucker rod is easier disconnected de-.So as to so that in crude oil production
Maintenance work amount increase, then unit crude oil cost improve constantly.So, it is very necessary to design a kind of airlock-resistant oil pump
's.
Utility model content：
The utility model makes up and improves above-mentioned the deficiencies in the prior art part, there is provided a kind of simple structure, design
Rationally, a kind of airlock-resistant oil pump that is safe and reliable, improving efficiency, reduces cost, be prevented from gas lock, can promote on a large scale
With use.
The technical solution adopted in the utility model is：A kind of airlock-resistant oil pump, including upper pump barrel, lower pump barrel and long-plunger,
Long-plunger is provided with cylindrical cavity, and cylindrical cavity top is fixed with pressure-reducing valve, and pressure-reducing valve includes that disk valve body and decompression rubber seal are blocked up, disk
Valve body is provided with seal plug pilot hole, exhaust ring cavity and steam vent, and decompression rubber seal is stifled to be located in seal plug pilot hole, exhaust
Six catch of circumference uniform distribution are provided with ring cavity；The long-plunger on described steam vent top is provided with gas port, gas port top
Cushion chamber is provided with, uniform four exhaust inclined hole is provided with around cushion chamber；Cylindrical cavity wall below the pressure-reducing valve is provided with
Four air inlet inclined holes of cloth.
The seal disc on the described stifled top of decompression rubber seal is located in the exhaust ring cavity below catch.
Described exhaust inclined hole and air inlet inclined hole be it is downward-sloping, and angle of inclination be 45 degree.
The position of cylindrical cavity is in the pump chamber of upper pump barrel on described long-plunger.
The beneficial effects of the utility model：Simple structure, it is reasonable in design, it is safe and reliable, improve efficiency, reduces cost, energy
Enough prevent gas lock, it is easy to promote on a large scale and use.When long-plunger is repeatedly completed upper and lower stroke, air pressure will be by pump chamber
Edge up height, and when upstroke is pumped, if air pressure is too high in pump chamber, decompression rubber seal is stifled then to move up, and gas passes through
Space and steam vent between seal plug pilot hole, exhaust ring cavity, catch is entered in wireway, then is discharged by being vented inclined tube, real
Now reduce pressure；If air pressure is too low in pump chamber, rubber seal of reducing pressure is blocked up on the end wall for then moving down and abutting in exhaust ring cavity, is played
The effect of sealing.
Description of the drawings：
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of pressure-reducing valve in the utility model.
Fig. 3 is the design attitude schematic diagram of pressure-reducing valve in the utility model.
Specific embodiment：
Reference picture is respectively schemed, a kind of airlock-resistant oil pump, including upper pump barrel 9, lower pump barrel 10 and long-plunger 2, and long-plunger 2 is provided with
Cylindrical cavity 6, the top of cylindrical cavity 6 is fixed with pressure-reducing valve 1, and pressure-reducing valve 1 includes disk valve body 102 and decompression rubber seal stifled 105, disc valve
Body 102 is provided with seal plug pilot hole 106, exhaust ring cavity 101 and steam vent 104, and decompression rubber seal stifled 105 is located at seal plug
In pilot hole 106, it is vented in ring cavity 101 and is provided with six catch 103 of circumference uniform distribution；The long column on the described top of steam vent 104
Plug 2 is provided with gas port 3, and the top of gas port 3 is provided with cushion chamber 4, and uniform four exhaust inclined hole 5 is provided with around cushion chamber 4；
The wall of cylindrical cavity 6 of the lower section of the pressure-reducing valve 1 is provided with uniform four air inlet inclined hole 7；Stifled 105 tops of described decompression rubber seal
