The action of the balanced hoisting type solenoid valve 10 of above-mentioned formation then, is described.
At first, shown in the double dot dash line in the enlarged view of Fig. 1 (a), not under the state of the coil 33a of electromagnetic portion 31 energising, movable core 35 iron core under poor (elastic force pressure) acts on the spring force between the spring 23 with valve with spring 36 quilt towards valve body 12 application of forces.The end face of first side of movable core 35 and support 12d butt.Poppet valve 41 is pressed in the valve body 12 by movable core 35, and spool 44 just sits on second valve seat 19.
Under this non-power status, the pressure of the positive pressure air at supplying mouth 13 places affacts on spool 44 and the sealed member assembly department 43b.At this moment, because spool 44 is configured to identical size with the compression area of sealed member assembly department 43b, so the pressure that affacts on spool 44 and the sealed member assembly department 43b cancels each other out.In addition, the pressure (barometric pressure) at delivery outlet 14 and exhaust port 15 places affacts on second S2 of pressure chamber from connectivity slot 42d between the axial region 42a of the second valve opening 12c through the support 12d and first valve rod 42.The first communication channel 42c of the pressure of second S2 of pressure chamber through first valve rod 42, and the second communication channel 43c of second valve rod 43 affact on first S1 of pressure chamber, first S1 of pressure chamber is in identical pressure with second S2 of pressure chamber.
Guarantee the sealing between first S1 of pressure chamber and the supplying mouth 13 (stream) through sealed member 45, prevent that the positive pressure air of first S1 of pressure chamber from leaking to supplying mouth 13.Therefore, poppet valve 41 bears identical power simultaneously and is maintained at state of equilibrium from its both sides.Therefore, 41 of poppet valves lean on iron core to sit on second valve seat 19 with the spring force difference of spring 23 with spring 36 and valve.In addition, the sealing between supplying mouth 13 and the delivery outlet 14 is guaranteed, can not export to delivery outlet 14 to the positive pressure air that supplying mouth 13 is supplied with.
When coil 33a was energized, movable core 35 was attracted to secured core 37.This attraction force surpasses the spring force of iron core with spring 36, when movable core 35 is adsorbed to 37 last times of secured core, poppet valve 41 valve with the elastic force pressure effect of spring 23 under quilt pushed towards electromagnetic portion 31.Like this, shown in Fig. 1 (a), spool 44 leaves from second valve seat 19, and just sits on first valve seat 18, and the stream of positive pressure air is switched.Its result supplies with positive pressure air from supplying mouth 13 to delivery outlet 14, supplies with positive pressure air from delivery outlet 14 to Pneumatic actuator.
At this moment, the pressure of the positive pressure air at supplying mouth 13 places affacts on spool 44 and the sealed member assembly department 43b.Because it is identical that the compression area of spool 44 and sealed member assembly department 43b is set to, cancel out each other with the pressure on the sealed member assembly department 43b so affact spool 44.In addition, the pressure at exhaust port 15 places affacts on second S2 of pressure chamber from connectivity slot 42d between the axial region 42a of the second valve opening 12c through the support 12d and first valve rod 42.The pressure of second S2 of pressure chamber affacts on first S1 of pressure chamber through first communication channel 42c of first valve rod 42 and the second communication channel 43c of second valve rod 43, and first S of pressure chamber 1 becomes identical pressure with second S2 of pressure chamber.At this moment, guarantee the sealing between first S1 of pressure chamber and the supplying mouth 13, leak to supplying mouth 13 with the positive pressure air that prevents first S1 of pressure chamber through sealed member 45.Thus, 41 of poppet valves lean on valve just to sit on first valve seat 18 with the spring force of spring 23, to guarantee the sealing between delivery outlet 14 and the exhaust port 15.
