Abstract

The utility model relates to energy storage equipment, in particular to an energy accumulator for an oil pumping unit. The technical scheme is that the energy accumulator mainly comprises a protective cap, a screw rod, a steel bottle, an air bag, a switch valve, a protection cork and a deflation plug; the air bag is fixed in the steel bottle; the screw rod is connected to the opening of the air bag; the protective cap is arranged at the top of the steel bottle; the switch valve is fixed at an opening at the bottom of the steel bottle through the protection cork; and the deflation plug is arranged on one side of the bottom of the steel bottle. The energy accumulator has the benefits that the screw rod replaces a valve rod, so that the waste caused owing to the fact that the air bag is replaced when the valve rod is damaged can be eliminated; the deflation plug at the bottom can ensure excellent leak tightness, so that the possibility of leakage can be minimized; and the cost is reduced, and the working efficiency is improved.

Description

The used for oil extractor accumulator
Technical field:
The utility model relates to a kind of energy storage system, particularly a kind of used for oil extractor accumulator.
Background technique:
In the field produces, be that switch wellhead blowout preventor group, hydraulic operated valve provide oil sources through accumulator, accumulator commonly used at present needs in time to change inner balloon because valve rod often damages, and causes the waste of air bag, has increased cost of production, has reduced working efficiency.
Summary of the invention:
The purpose of the utility model is exactly the above-mentioned defective that exists to existing technology, and a kind of used for oil extractor accumulator is provided.
Its technological scheme is: mainly be made up of helmet, screw rod, steel cylinder, air bag, switch valve, protective plug, expanding plug; The internal fixation air bag of steel cylinder; Air bag opening place connecting screw rod; The top of steel cylinder is provided with helmet, and the bottom opening of steel cylinder is through protective plug floatless switch valve, and bottom one side of steel cylinder is provided with expanding plug.
The beneficial effect of the utility model is: replace valve rod through using screw rod; Eliminated because of valve rod damages and changed the waste that air bag causes, the bottom is provided with expanding plug can provide good sealing, makes the possibility of leakage reduce to minimum; Reduce cost, increase work efficiency.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: helmet 1, screw rod 2, steel cylinder 3, air bag 4, switch valve 5, protective plug 6, expanding plug 7.
Embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of helmet 1, screw rod 2, steel cylinder 3, air bag 4, switch valve 5, protective plug 6, expanding plug 7; The internal fixation air bag 4 of steel cylinder 3; Air bag 4 opening connecting screw rods 2; The top of steel cylinder 3 is provided with helmet 1, and the bottom opening of steel cylinder 3 is through protective plug 6 floatless switch valves 5, and bottom one side of steel cylinder 3 is provided with expanding plug 7.
During use, through electric oil pump pressure oil is imported in the steel cylinder, the oil mass in the steel cylinder increases gradually, and oil pressure raises; The hydraulic oil extruding gasbag is compressed the nitrogen in the air bag, and pressure raises, when reaching certain pressure; The operation four-way turns to preventer, and the nitrogen expansion in the air bag is extruded oil, and when pressure was reduced to certain pressure, supplementary pressure was oily in steel cylinder again; Through using screw rod to replace valve rod, to have eliminated because of valve rod damages and changed the waste that air bag causes, the bottom is provided with expanding plug can provide good sealing; Make the possibility of leakage reduce to minimum, reduce cost, increase work efficiency.
