Description
Technical field
The invention belongs to field of hydraulic equipment, particularly a kind of self-action booster for hydraulic tool.
Background technology
Bearing installation, frock clamp, explosion test etc. are mainly used in the pressure booster used at present, generally uses pumping plant to provide first class pressure, carrying out frequently commutation using outside reversal valve makes internal pressurization cylinder move back and forth so as to reach supercharging output.But find there is following point in actual use.
1st, outside reversal valve commutation is too fast, and front end high cavity easily weares and teares and high-pressure chamber pressure does not reach design standard, easily makes to be heated up by charging fluid.
2nd, outside reversal valve commutated slowly, front end high chamber pressure discharge after can not continuous oil supply, cause hydraulic tool resilience or can not work, associated safety problem can be caused when serious.
3rd, high-voltage output end needs reversal valve pressure release outside bypass pressure release or application overpressure resistant, so not only makes outside reversal valve short life, and cost is high, bulky.
4th, because current booster operation principle is the commutation of external electrical magnet valve, pressurized cylinder internal reset is made by hydraulic power source, so being that hydraulic power source can not be other media by charging fluid.
5th, because current booster operation principle is unidirectional reciprocal fuel feeding, it can be only applied to the less occasion of flow-rate ratio.
The content of the invention
The mesh of the present invention is essentially consisted in, a kind of self-action booster can carry out internal automatic reverse, releasing pressure automatically using hydraulic pressure input source, ensure the complete supercharging output of each chamber oil, mechanical efficiency is high, pressurized cylinder is preferably minimized with supercharging cavity abrasion probability, realizes a kind of device that pressure is smoothly exported, it is overall succinct durable, it is reliable and stable, compact, service efficiency is higher and can be used in the occasion of big flow.
In order to achieve the above object, it is integrated by the hydraulic circuit that supercharging cavity, pressurized cylinder, check valve, hydraulic control one-way valve, pilot operated directional control valve are constituted inside a kind of self-action booster of patent of the present invention；Wherein, pressurized cylinder is provided with booster cavity body, supercharging cavity two ends connect two check valves as by the import and export of charging fluid respectively, two pairs of oil circuits are opened in the middle of supercharging cavity and charged piston intermediate annular groove matches, make one end and oil inlet or the oil return opening UNICOM of pilot operated directional control valve respectively by these two pair oil circuit by annular groove when pressurized cylinder is moved back and forth, so that pilot operated directional control valve automatic reverse, pilot operated directional control valve is in diverse location to the two commutation one of oil-feed of cavity another oil returns, pressurized cylinder is moved back and forth again, realize that automatic reverse is pressurized.
A kind of self-action booster of the present invention, supercharging cavity two ends are connected by check valve with outside by charging fluid source, can be inputted the fluid media (medium)s different from pressure source and are pressurized, fluid input source is in parallel with hydraulic power source during same media.
Advantages of the present invention is as follows：Realize that automatic reciprocating realize is pressurized after hydraulic power source input, integral pressure is steady, improved efficiency is obvious so that reciprocal time is reduced, improve the overall work life-span, and charging fluid and hydraulic power source can be different medium, it can apply to chemical industry or other special industries, it is overall compact to be easy to encapsulation and be completely suitable for using under adverse circumstances.
Brief description of the drawings
Shown in Fig. 1, structural representation of the invention, as shown in the figure：Pilot operated directional control valve 1, output one-way valve 2 inputs check valve 3, and hydraulic control one-way valve 4, plenum body 5 inputs check valve 6, output one-way valve 7.Correlation mark is as follows：Hydraulic pressure input port P, oil return inlet T, super-pressure delivery outlet H, charging fluid import P0, pilot operated directional control valve input port P1, pilot operated directional control valve delivery outlet T1, T2, pilot operated directional control valve delivery outlet A, B, pressurized cylinder V, it is pressurized cavity V0, V1, commutate cavity V2, V3, annular groove O, connector C1, C2, D1, D2, Z1, Z2.
Embodiment
As shown in Fig. 1, a kind of self-action booster of the present invention uses global design, wherein hydraulic power source enters input port P connection pilot operated directional control valves input port P1, pilot operated directional control valve delivery outlet T1, T2 connects delivery outlet T respectively, pilot operated directional control valve delivery outlet A, B connects V2 respectively, the connector Z1 at V3 commutation cavitys two ends, Z2, wherein there is annular groove O in the middle of internal pressurization cylinder, when pressurized cylinder is moved back and forth respectively with C1, C2 or D1, D2 is connected, it is pressurized cavity V1 two ends respectively connecting fluid input check valve 3, 6 and output one-way valve 2, 7, charging fluid enters after supercharging cavity V1 from P0 mouthfuls from super-pressure delivery outlet H outputs.
The course of work：When system has hydraulic power source input port P, pilot operated directional control valve 1 is entered by input port P1, the commutation of the valve of liquid controlled reversing 1 is promoted to make input port P1 and delivery outlet A UNICOMs simultaneously, input port Z1 of the hydraulic power source from pilot operated directional control valve delivery outlet A into plenum body 5 is pressurized supercharging cavity V1 to commutation cavity V2 topping ups, exported from check valve 7 to super-pressure delivery outlet H, pressurized cylinder V is promoted cavity V3 is flowed out to delivery outlet T2 oil returns through the delivery outlet B of pilot operated directional control valve 1 by connector Z2 simultaneously, charging fluid is input to the topping up in supercharging cavity V0 of check valve 3 from import P0 simultaneously, when annular groove O in the middle of pressurized cylinder is moved at connector D1/D2, hydraulic power source flows into connector D2 by connector D1 makes the both sides pressure balance of pilot operated directional control valve 1 and return.
Further, hydraulic power source import P hydraulic pressure with delivery outlet B UNICOMs and promotes pressurized cylinder commutation chamber V2 is output to delivery outlet T1 oil returns by the connector A of connector Z1 to pilot operated directional control valve 1 by the input port P1 of pilot operated directional control valve 1 by the connector Z2 commutation chamber V3 for entering plenum body 5, booster cavity V1 is output to super-pressure delivery outlet H by check valve 2 simultaneously, other end input port P0 fluids enter supercharging cavity V0 by check valve 6 and carry out topping up, in the middle of pressurized cylinder when changing at annular groove O to connector C1/C2, the end pressure of pilot operated directional control valve 1 one flows out connector C1 oil returns and pressure release by connector C2, the one end for making pilot operated directional control valve 1 connect hydraulic power source P, which is under pressure, is commutated, and so on.
Further, when super-pressure delivery outlet H needs pressure release, feeding hydraulic power source opening hydraulic control one-way valve 4 to oil return inlet T makes it be discharged from charging fluid import P0.
It is intensification factor according to the difference of the sectional area of ratio calculating commutation cavity and the sectional area of booster cavity, then than the sectional area of upper booster cavity when needing different intensification factors.
A kind of each element of self-action booster of the invention can be connected with highly integrated without pipeline, can be used without leakage, efficient operation so as to stable for a long time under rugged environment.
