Embodiment
Device 10 of the present invention comprises a memory 12.Memory 12 comprises the sealed pressure vessel 14 that has predetermined internal volume 16 and have predetermined small amount of liquid 18 (for example oil) within it.The reason of doing like this is, liquid is compared with gas, and liquid is less from the possibility that oil hydraulic cylinder spills, and compressible possibility is much smaller under pressure, thereby also just more reliable.Memory 12 has one to allow gas to enter and make internal volume 16 and memory 12 interior liquid 18 to have the suction valve 20 of pressure.Pressure gauge 22 communicates with memory 12.Pressure gauge 22 shows the pressure of "on" and "off", will be discussed below.The thin liquid flow tube 24 on the end and oil hydraulic cylinder 26 right sides 28 of two connection memories 12 is arranged, make fluid communication between the two.Pressure gauge 22 shows that visually liquid flows into the pressure of sealed pressure vessel 58 (opening) and the liquid pressure of (passs) that stops to flow, and represents that sealed pressure vessel is full.Gas with pressure is inert gas preferably.
Oil hydraulic cylinder 26 has a piston 30 that is positioned at the sealing of its band push rod 32.The second hydraulic fluid pipe 34 is connected with oil hydraulic cylinder 26 in the left side 36 of oil hydraulic cylinder.The second hydraulic fluid pipe 34 also is connected with the liquid stream connection set (for example t-shaped connector 38 this forms) in downstream, and the fluid communication in both.Push rod 32 has first geared assembly of tooth bar 40 and so at its end.Also can use other geared assemblies instead.Tooth bar 40 is taken on sprocket 42.Sprocket 42 connects fluid valve 44 (for example ball valve) and is used for the described valve 44 of opening and closing.Tooth bar 40 and sprocket 42 also can be used the motion of known allowed piston in hydraulic cylinder 30 instead and other connection sets of control valve 44.Valve 44 has liquid or air approaching side 46 and a liquid to emit side 48.The liquid that injects sealed pressure vessel 58 is annotated the liquid or the air approaching side 46 of valve 44 by liquid supply tube 50.Liquid supply tube 50 is connected with bigger fluid supply again, for example the oil car (not shown) by the pump supply fluid.Liquid or air approaching side 46 and emit side 48 and preferably each have decompressor 52 and 54 is to reduce fluid pressure fluctuation and the injection by valve 44.Flow of liquid flows out and emits side 48 through valve 44, enters t-shaped connector 38 again.As Fig. 1 clearly illustrates, adopt liquid supply hose 56 liquid to be injected the sealed pressure vessel 58 for the treatment of fluid injection.Also a pressure valve 60 can be installed on t-shaped connector 38, with the fluid pressure in the monitoring t-shaped connector 38 (thereby also monitor in the sealed pressure vessel 58 fluid pressure).Discussed below the other safety feature.A locking framework 62 preferably can be arranged, when sealed pressure vessel 58 is filled with liquid, make valve 44 remain in closed position automatically.Shown a kind of such locking framework 62 among the figure, it comprises the rotation disposition of latch arm 64 of a band locking head 66, wherein, locking head 66 is taken slidably on tooth bar 40, arrive right positions up to tooth bar 40 and just mesh, make sprocket 42 clockwise directions rotations (thereby cut-off valve 44) with this with it.As clearly illustrating among Fig. 3, on this position, locking head 64 can stay in after the tooth bar 40 and (perhaps on the locking point of tooth bar 40, show), thereby prevents that tooth bar 40 from rotating sprocket 42 again, thereby fluid valve 44 can not opened unintentionally.
The following describes device 10 operating situations.When liquid enters system from liquid or air approaching side 46, the valve 44 of flowing through, when entering liquid again and emitting side 48, pressure descends because internal diameter of the pipeline reduces that internal diameter with valve 44 reduces.
Referring to Fig. 1, liquid supply hose 56 is connected in sealed pressure vessel 58 by flexible pipe 68.For convenience's sake, liquid supply hose 56 can a liquid joint 70 that have for connection flexible pipe 68.Liquid joint 70 is preferably installed a device that prevents the liquid in the sealed pressure vessel 58 and advance the gas effusion of gas-bearing formation.Sealed pressure vessel 58 is used to deposit the preferably pressurized propulsive gas of the inert gas of nitrogen and so on of the liquid of hydraulic oil or motor-oil and so on and one deck.Along with flow of liquid enters sealed pressure vessel 58 through valve 44, t-shaped connector 38 and flexible pipe 56, the pressure of propulsive gas can strengthen owing to can hold the volume reducing of gas in the sealed pressure vessel 58.For example, sealed pressure vessel charges into the nitrogen of 20 pounds of pressure approximately per square inch in empty.When sealed pressure vessel about 80 to 90 percent was expired, perhaps the pressure of nitrogen can rise to 80 to 100 pounds approximately per square inch.This makes, and the liquid in the flexible pipe 56 has pressure in the injection process.T-shaped connector also is subjected to this pressure with the second hydraulic fluid pipe, the 34 interior liquid that are connected in oil hydraulic cylinder 26 left sides 36.As previously mentioned, the liquid of the predetermined pressure of being subjected to is arranged in memory 12, the liquid on the right side 28 of this liquid and oil hydraulic cylinder 26 links.When surpassing from memory 12 through managing 24 when entering the pressure of pressure fluid on oil hydraulic cylinder 26 right sides 28 with the suffered pressure in oil hydraulic cylinder 26 left sides of liquid in the second hydraulic fluid pipe 34, the piston 30 of sealing just moves.This moves tooth bar 40 is moved, and described tooth bar is taken on the sprocket 42 that is connected valve 44.At suitable pressures, valve 44 leaves and closes, and a kind of automatic cutting off table structure is provided, and controlling liquid flows into sealed pressure vessel 58.
In fact, the internal volume that provides for memory 12 is approximately 100 times of oil hydraulic cylinder 26 volumes, and device 10 work are just very accurate and provide cut-off valve 44 required enough moment.Device 10 at work, liquid are under the predetermined pressure situation in the sealed pressure vessel 58, piston 30 can promote steadily and promptly sliding closing valve 44 of tooth bars 40, and locking framework can prevent that valve 44 from being opened again, unless the user has a mind to make it restore.
This new invention is showed an important improvement to this specialty, because it makes the sealed pressure vessel that advances gas-bearing formation can be safely and effectively refill liquid from the high pressure liquid source of irritating into liquid tank and so on high pressure more, and cuts off liquid stream automatically when container is filled.
With regard to concrete making method and working method, be not intended to scheme with above stated specification as unique form of the present invention.In fact, for those skilled in the art, do not depart from the scope of the present invention and spirit can be made various modifications and modification is clearly.Though used specific word to be intended to general remark, meaning without limits.
