Abstract
The utility model relates to a liquid/gas energy storage device used in a hydraulic or pneumatic system which comprises a hydraulic/pneumatic cylinder, a piston, and a piston rod. The utility model is characterized in that: a pressure spring is arranged between the piston in the hydraulic/pneumatic cylinder and the top cover of the hydraulic/pneumatic cylinder, the piston rod penetrates through the pressure spring and extends out of the top cover, a position detecting device is arranged on the extending end of the piston rod, and a liquid/gas inlet/outlet is arranged on the lower part relative to the extending end of the piston rod. As the device adopts the pressure spring as an energy storage element, liquid and gas can not mix up. Simultaneously, as the position detecting device is arranged on the piston rod, the utility model can be used separately or in multiple joints according to requirements of various digital control hydraulic/pneumatic systems. The utility model which has the advantages of easy manufacture, high price performance ratio, easy maintenance and use, high sensitivity, safety and reliability, and long service life can be widely used in various hydraulic/pneumatic systems of digital control devices.
Description
Technical field
The utility model relates to a kind of liquid/gas energy storage device that uses in hydraulic pressure or pressure system.
Background technique
Accumulator is one of very important device in hydraulic pressure or pressure system, it can absorb the impact of liquid/gas system effectively, the flow in the replenishment system fast simultaneously, play energy storage, cushion and reduce the effect of system installed capacity, therefore, accumulator has obtained to use widely in the liquid/gas system.
Accumulator at present commonly used has gas-liquid direct contact type, piston type and bladder etc.Gas in the gas-liquid direct contact type accumulator is sneaked in the pipeline easily in a large number, causes system's concussion and less employing; Piston accumulator is used and is also pursued minimizing because problems such as design, selection are easy to cause leakage after the hermetic unit wearing and tearing.The present comparatively bladder accumulator of extensive use, although this accumulator has more advantage, but leather bag exists problems such as weak point in working life, after leather bag breaks, becoming gas-liquid directly contacts, gas can enter in the pipeline in a large number, cause liquid (gas) system failure, make its liquid (gas) system can't proper functioning, after breaking, leather bag is difficult to again find, when cisco unity malfunction appears in system, could find the fault point up to whole liquid (gas), liquid (gas) body that enters liquid (gas) system be discharged very trouble.In addition, these present several accumulators are to carry out interface with numerical control system.
The model utility content
The liquid/gas energy storage device that the utility model provides adopts spring as energy-storage travelling wave tube, has overcome the problem of system's shakiness that gas-liquid mixed caused, and simultaneously solenoid valve and position detecting device has been installed on energy storage device, can adapt to the requirement in the numerical control device.
The technical solution of the utility model is: a kind of liquid/gas energy storage device, comprise liquid/gas cylinder pressure, piston, piston rod, it is characterized in that between piston in the liquid/gas cylinder pressure and the liquid/gas cylinder pressure top cover stage clip being installed, piston rod passes stage clip and stretches out top cover, at the piston rod external part position detecting device is installed, has into/fluid/gas port in the bottom relative with the external part of piston rod.
The position detecting device of installing on the external part of above-mentioned piston rod can be position limit switch or optoelectronic switch or hall device.
Above-mentioned position detecting device is formed by being installed in two position detecting devices in piston rod external part upper and lower.
Above-mentionedly advancing/can connect more than one this liquid/gas energy storage device by solenoid valve on fluid/gas port.
Characteristics of the present utility model are, owing to adopt spring as energy-storage travelling wave tube, so there be not mixing between liquid and the gas, position detecting device has been installed on piston rod simultaneously, so just can be according to the independent use of needs or the multi-joint use of all kinds of numerical controls, liquid/gas system.This device have make simple, performance and price is stronger, maintenance is easy, the advantage of easy to use, highly sensitive, safe and reliable, long service life, can be widely used in the middle of the liquid/gas system of all kinds of numerical control devices.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, between piston 2 in liquid/gas cylinder pressure 9 and liquid/gas cylinder pressure 9 top covers stage clip 4 is installed, piston rod 3 passes stage clip 4 and stretches out top cover, position detecting device 6 is installed on the external part of piston rod 3, this position detecting device 6 can be position limit switch or optoelectronic switch or hall device, has into/fluid/gas port 1 in the bottom relative with the external part of piston rod 3.
This liquid/gas energy storage device is with after the liquid/gas system is connected, and high pressure liquid/gas enters in the liquid/gas cylinder pressure 9 from feed liquor/gas port 1, overcomes the reaction force of stage clip 4, makes piston 2 move up.The bottom of the external part of piston rod 3 is equipped with position detecting device 6, this position detecting device 6 can be position limit switch or optoelectronic switch or hall device, after position detecting device 6 moves with piston rod 3, with regard to the enable position detection device, send an electrical signal by position detecting device to the solenoid valve 8 that is installed on feed liquor/gas port 1, solenoid valve is opened, high pressure liquid/gas enters second liquid/gas energy storage device from the pipeline 7 that links to each other with feed liquor/gas port 1, when two piston rods 3 move all move to the extreme higher position after, when just the stored energy of liquid/gas energy storage device is maximum, position detecting device starts, send an electrical signal to solenoid valve 8, make closed electromagnetic valve.When the liquid/gas system needs energy storage device to release energy, control section by system sends signal to solenoid valve, solenoid valve is opened, stored energy is discharged by feed liquor/gas port 1, provide the energy of moment to system,, promptly discharge high pressure up to zero-pressure from the liquid/gas energy storage device when the piston of liquid/gas energy storage device is moved to zero point, thereby finished a work cycle, waited for next instruction.The utility model can be connected with system by liquid/gas energy storage device independently, also can connect several according to the needs of system.The utility model is suitable for pursuing of numerical control device, the super smart equipment feeding system of numerical control slow (discharge high pressure from the energy storage machine and solve rib garden precision problem up to zero-pressure), static pressure axle, dynamic and hydrostatic hang-up, liquid systems such as (gas).
