Embodiment
As shown in Figure 1, the utility model is by electric proportional pressure valve 1, selector valve 2, actuator chamber left end cap 3, actuator chamber right end cap 4, drive cylinder body 5, left side pilot valve 6, right pilot valve 7, driven plunger 8, charged piston 9, piston brace rod 10, supercharging cylinder body 11, booster cavity end cap 12, cooling cylinder sleeve 13, breather check valve 14, exhaust check valve 15, muffler 16, bearing pneumostome 17, air inlet pressure sensor 18, back pressure transducer 19 and controller 20 are formed, electric proportional pressure valve 1 is installed in, on the actuator chamber right end cap, selector valve 2 is installed in and drives in the right end cap 4, by the no bar side of driven plunger 8 with bar side collision left side pilot valve 6 and right pilot valve 7 are arranged, to the venting of removing heat by catharsis of selector valve 2 spool two ends, the automatic switchover of control selector valve 2; Left side pilot valve 6 and right pilot valve 7 lay respectively in actuator chamber left end cap 3 and the actuator chamber right end cap 4, actuator chamber is made up of actuator chamber left end cap 3 and actuator chamber right end cap 4, driving cylinder body 5 and driven plunger 8, booster cavity is made up of supercharging cylinder body 11, booster cavity end cap 12 and charged piston 9, and piston brace rod 10 passes actuator chamber right end cap 4 driven plunger 8 and charged piston 9 are linked together; Breather check valve 14 and exhaust check valve 15 are embedded in the booster cavity end cap 12.Cooling cylinder sleeve 13 is installed in supercharging cylinder body 11 peripheries, bearing pneumostome 17 is installed on the actuator chamber right end cap 4, baffler 16 is fixed on the cooling cylinder sleeve 13, and controller 20 is installed on the actuator chamber right end cap 4, and air inlet pressure sensor 18 and back pressure transducer 19 are installed on the intake and exhaust pipeline.
As shown in Figure 2, the utility model can be a manual tune, and manual tune reduction valve in the process of supercharging is heightened the pressure of the gas of supplying with actuator chamber gradually.
The utility model working procedure is: just logical going up when driving source of the gas, and selector valve 1 at first is positioned at position, a left side under the promotion of propellant, and propellant enters the driving rodless cavity through the P of selector valve 2 mouth and A mouth, promotes driven plunger 8 and carries out compression stroke.In this trip process, drive the interior gas of rod chamber and be discharged in the cooling cylinder sleeve 13 through the B of selector valve 2 mouth and R mouth, gases are discharged through exhaust check valve 15 under the compression of charged piston 9 in the supercharging cylinder body 11.When moving to the compression stroke end, driven plunger 8 touches right pilot valve 7, makes the ventilation of selector valve 2 big piston sides, and selector valve 2 commutations are to right.Propellant enters the driving rod chamber through the P of selector valve 2 mouth and B mouth, the beginning suction stroke, and low-pressure gas is in breather check valve 14 enters supercharging cylinder body 11.In the suction stroke process, drive the interior gas of rodless cavity and be discharged to cooling cylinder sleeve 13, after baffler 16 is discharged into atmosphere through the A of selector valve 2 mouth and R mouth.When piston ran to the suction stroke end, driven plunger 8 touched left pilot valve 6, and selector valve 2 big piston end gases are released, and selector valve 2 switches to position, a left side once more, realized the continuous working in reciprocating mode of pressurized machine.
In the continuous reciprocal pressurization of gas booster, the pressure of gas is gathered before and after 19 pairs of superchargings of air inlet pressure sensor 18 and back pressure transducer, and with the data transmission that collects to controller 20; 20 pairs of barometric informations that receive of controller are handled, and send control signal to electric proportional pressure valve 1 afterwards, the aperture of regulating and controlling valve.Electric proportional pressure valve 1 is installed in actuator chamber right end cap 4 propellant air supply opening places.In the load of supercharging initial stage hour, supply with the propellant of the less pressure of pressurized machine, along with the rising of exhaust pressure, increase the pressure of propellant gradually, thereby realized reducing the purpose of pressurized machine propellant air consumption.
