Described high pressure cylinder barrel 8 is separately positioned on the end of front cover 3, rear end cover 4, is furnished with tetra-one-way valves 9 of two one-way valve 9(and is divided into one-way valve 9-1,9-2,9-3,9-4 on each high pressure cylinder barrel 8).
Described pilot valve 11 is integrated in respectively in front cover 3, rear end cover 4, and its Main Function is the gas path on-off of control integration valve 5, and it is in normally off.Wherein, pilot valve 11 labels in front cover 3 are 11-1; Pilot valve 11 labels in rear end cover 4 are 11-2.
Described integrated valve 5 is provided with suction port A1, relief opening A2, working hole B1, working hole B2, controls mouthful C1 and controls a mouthful C2.The gas circuit I in the interior formation of the working hole B1 on described integrated valve 5 and front cover 3 one air-flow turnover low pressure cylinder barrel 1 left chamber; Working hole B2 on integrated valve 5 is by the gas circuit II in the interior formation of air pipe 7, flow guiding head 6 and rear end cover 4 one air-flow turnover low pressure cylinder barrel 1 right chamber.The control mouth C2 of the control mouth C1 of described integrated valve 5, front cover 3, integrated valve 5 forms control gas circuit I, and the pilot valve 11 in front cover 3 is positioned on this control gas circuit I; The control mouth C1 of described integrated valve 5 and rear end cover 4 form controls gas circuit II, and the pilot valve 11 in rear end cover 4 is positioned at controls gas circuit II.
Further, be provided with M chamber and N chamber in described integrated valve 5, this M chamber and a control mouthful C1 communicate, and N chamber and a control mouthful C2 communicate.
The working principle of integrated valve type gas drive liquid suction booster of the present invention is as follows: propellant enters the left chamber of low pressure cylinder barrel 1 through integrated valve 5, promote charged piston 2, charged piston 2 drives plunger 10 to move right, liquid enters the left chamber of high pressure cylinder barrel 8 through one-way valve 9-1, liquid in the right chamber of high pressure cylinder barrel 8 is through one-way valve 9-3 ramming system, and one-way valve 9-2, one-way valve 9-4 are airtight under pressure; Gas in the right chamber of low pressure cylinder barrel 1 is discharged through integrated valve 5.When charged piston 2 right laterals are during to end of travel, piston end surface promotes the spool of pilot valve 11-2, integrated valve 5 commutations.Now, propellant enters the right chamber of low pressure cylinder barrel 1 through integrated valve 5, piston driving plunger 10 moves right, by the liquid in the left chamber of high pressure cylinder barrel 8 through one-way valve 9-2 ramming system, liquid enters the right chamber of high pressure cylinder barrel 8 through one-way valve 9-4, one-way valve 9-1, one-way valve 9-3 are airtight under pressure; Gas in the left chamber of low pressure cylinder barrel 1 is discharged through integrated valve 5.When charged piston 2 left lateral are during to end of travel, piston end surface promotes the spool of pilot valve 11-1, and integrated valve 5 commutates again.When the hydraulic action on acting on plunger 10 balances each other with the gas pressure power on charged piston 2 of acting on, charged piston 2 will stop motion; When the pressure drop of hydraulic system is during to certain value, while having lost state of equilibrium, charged piston 2 is setting in motion again.
The motion mode of each air flow direction and spool 52 when suction booster work is below described.Propellant enters N chamber through the suction port A1 of integrated valve 5, when integrated valve 5 is during in working position, gas in N chamber flows into gas circuit I by the hole by valve pocket 53, by gas circuit I, flowed into the left chamber of low pressure cylinder barrel 1, promote charged piston 2 right laterals, gas in the right chamber of low pressure cylinder barrel 1 flows into integrated valve 5 through gas circuit II, finally by the relief opening A2 on valve body, is discharged.When charged piston 2 right laterals are during to end of travel, charged piston 2 end faces promote the pilot valve 11-2 in rear end cover 4, M chamber in integrated valve 5 is communicated with atmosphere through controlling gas circuit II, and the spool 52 of integrated valve 52 moves to working position under atmospheric pressure effect, thus change airflow direction.Propellant still enters N chamber by the suction port A1 on valve body 51, when spool 52 is during in working position 2, gas flows into gas circuit II by another hole, road by valve pocket 53, by gas circuit II, flowed into again the right chamber of low pressure cylinder barrel 1, promote charged piston 2 left lateral, gas in the left chamber of low pressure cylinder barrel 1 flows into integrated valve 5 through gas circuit I, then the relief opening A2 on valve body discharges.When the end face of driven plunger 5 leaves pilot valve 11-2, the spring force on pilot valve 11-2 promotes pilot valve 11-2 thereupon and resets, and disconnects and controls gas circuit II.When charged piston 2 left lateral are during to end of travel, charged piston 2 end faces promote the interior pilot valve 11-1 of front cover 3, M chamber in integrated valve 5 is communicated with N chamber through controlling gas circuit I, because 52 liang of end sections of spool have area difference, spool 52 will be under differential pressure action mobile switching gas circuit.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
