Abstract

One kind being able to achieve pressure adjustable, variable volume, the plunger and spring assembly loading type hydraulic accumulator of gas-liquid isolation.It is by intake valve, air outlet valve, range sensor, inflatable chamber, plunger upper plate, spring, plunger lower plate, oil-filled chamber, oil outlet, shell composition.The accumulator utilizes range sensor, the cooperating of intake valve and air outlet valve, can volume to oil-filled chamber and oil liquid pressure carry out control variation, when the accumulator, which only does buffering, to be used, guarantee that plunger upper plate and housing upper surface distance are certain by range sensor output signal, the combined energy-accumulation device becomes spring accumul ator at this time, a but adjustable volume function more than traditional spring accumul ator, the accumulator can adjust the volume change of oil-filled chamber in time, so that entire combined energy-accumulation device work is more flexible, realize gas-liquid isolation, and structure is simple, equipment compatibility is good.

Description

A kind of plunger and spring assembly loading type hydraulic accumulator
Technical field
The utility model relates to a kind of hydraulic pressure auxiliary elements, are especially able to achieve gas-liquid isolation, a kind of plunger of variable volume With spring assembly loading type hydraulic accumulator.
Background technique
Currently, traditional accumulator can be divided into three categories: gravitational load formula (Weight type), bullet according to the difference of way of energy storage Spring loading type (spring) and gas loaded type.Weighted accumulator pressure is constant, and volume is big, heavy and low-response;Spring adds Load formula accumulator structure is simple, is quick on the draw, but capacity is small and fixed, is suitble in the case where low-pressure system cycle frequency is low Accumulation of energy and buffering use;Airloaded accumulator gas is easily mixed into oil, influences hydraulic system stationarity.These three hydraulic storages Energy device cuts both ways, and cannot realize pressure adjustable, variable volume, the technical indicator of gas-liquid isolation simultaneously.
Utility model content
It is controllable in order to overcome existing hydraulic accumulator that cannot meet oil liquid pressure simultaneously, volume variation is adjustable and gas-liquid every From requirement, the utility model provides a kind of plunger and spring assembly loading type hydraulic accumulator, which adds with spring assembly Load formula hydraulic accumulator is able to achieve the target of controllable pressure and oil pocket volume.
The technical scheme adopted by the utility model to solve the technical problem is as follows: by intake valve, air outlet valve, Distance-sensing Device, inflatable chamber, plunger upper plate, spring, plunger lower plate, oil-filled chamber, oil outlet, shell is constituted, it is characterized in that: range sensor, Intake valve and air outlet valve are successively fixed on case top from left to right, and plunger upper plate and plunger lower plate are connected by spring, Inside housings and slidably, plunger upper plate and housing upper surface form inflatable chamber, plunger lower plate and housing lower surface shape for installation At oil-filled chamber, oil outlet is provided in housing bottom.When needing accumulator to store oil liquid, oil liquid enters oil-filled chamber by oil outlet, At this time since the pressure of oil liquid acts on, the volume of inflatable chamber is caused to become so that plunger upper plate, spring and plunger lower plate move up Small, internal gas is discharged by air outlet valve.When needing that oil liquid is discharged, inert gas enters inflatable chamber by intake valve, goes out at this time Air valve is closed so that inflatable chamber volume increases, and plunger upper plate, spring and plunger lower plate move down, and oil-filled chamber inner fluid is by fuel-displaced Mouth discharge.When the accumulator only needs to buffer in use, being adjusted by intake valve air inlet and being gone out by range sensor output signal The volume of air valve exhaust guarantees that plunger upper plate and housing upper surface distance are certain, and the combined energy-accumulation device becomes spring storage at this time Can device, low-pressure system accumulation of energy and buffering in the case where cycle frequency is low can be met and used, but it is than traditional spring accumul ator More adjustable volume functions, the volume which can adjust in time oil-filled chamber by the output signal of range sensor become Change, so that the work of entire combined energy-accumulation device is more flexible, and plunger upper plate, spring, plunger lower plate makes inflatable chamber and oil-filled Chamber isolation realizes gas-liquid isolation, and oil liquid is not oxidizable, when needing to pressurize to fluid pressure in oil-filled chamber, inlet open, Air outlet valve is closed, and inflatable chamber volume can be made constantly to become larger, fluid pressure becomes larger in oil-filled chamber.
The utility model has the beneficial effects that using range sensor, the cooperating of intake valve and air outlet valve can be to filling The volume and oil liquid pressure of oil pocket carry out control variation, due to accumulator structure feature, and gas-liquid can be made to be isolated, and structure letter Single, equipment compatibility is good.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the cross-sectional view of the utility model.
In figure, 1. intake valves, 2. air outlet valves, 3. range sensors, 4. inflatable chambers, 5. plunger upper plates, 6. springs, 7. plungers Lower plate, 8. oil-filled chambers, 9. oil outlets, 10. shells
Specific embodiment
In the various figures, range sensor, intake valve and air outlet valve are successively fixed on case top, plunger upper plate from left to right It is connected with plunger lower plate by spring, inside housings and slidably, plunger upper plate and housing upper surface formation are filled for installation Air cavity, plunger lower plate and housing lower surface form oil-filled chamber, are provided with oil outlet in housing bottom.
When needing accumulator to store oil liquid, oil liquid enters oil-filled chamber (8) by oil outlet (9), at this time due to the pressure of oil liquid Power effect, causes the volume of inflatable chamber (4) to become smaller so that plunger upper plate (5), spring (6) and plunger lower plate (7) move up, Internal gas is discharged by air outlet valve (2).When needing that oil liquid is discharged, inert gas enters inflatable chamber (4) by intake valve (1), this When air outlet valve (2) close so that inflatable chamber (4) volume increases, plunger upper plate (5), spring (6) and plunger lower plate (7) are to moving down Dynamic, oil-filled chamber (8) inner fluid is discharged by oil outlet (9).When the accumulator only needs to buffer in use, by range sensor (3) output signal adjusts the volume being vented by intake valve (1) air inlet and air outlet valve (2), guarantees plunger upper plate (5) and shell (10) Upper surface distance is certain, and the combined energy-accumulation device becomes spring accumul ator at this time, and it is low in cycle frequency can to meet low-pressure system In the case of accumulation of energy and buffering use, but its adjustable volume function more than traditional spring accumul ator, the accumulator can pass through The output signal of range sensor (3) adjusts the volume change of oil-filled chamber (8) in time, so that entire combined energy-accumulation device work is more Flexibly, and plunger upper plate (5), spring (6), plunger lower plate (7) are isolated inflatable chamber (4) and oil-filled chamber (8), realize gas Liquid isolation, oil liquid is not oxidizable, and when needing to pressurize to oil-filled chamber (8) interior fluid pressure, intake valve (1) is opened, air outlet valve (2) It closes, inflatable chamber (4) volume can be made constantly to become larger, oil-filled chamber (8) interior fluid pressure becomes larger.
