When using as 5/2 valve type, this valve body can be installed in the cylinder pressure 100, the 3rd 13 side that is provided with observing window 131 (as Fig. 2) of

valve body body

10,70 groups of base plates are gone into second of body 10 when closely connected, 5/2 valve type of base plate 70 fourth faces 74 indicates to be seen to look by observing window 131 and learns, the through hole 77 of this base plate 70, corresponding respectively two gateways 101 of establishing that connect of through hole 78 to cylinder pressure 100,102 (as Fig. 9 A, Figure 14), when one one of them gateway 101 for this cylinder pressure 100 is the air inlet state, 102 need in another gateway are exhaust condition, and are installed with one in the 5th 15 of this body 10 and can open, close the solenoid valve 80 of this first through hole 811.

As shown in figure 14, be applied to the air pressure driving device, not start of solenoid valve 80, two elastomers 64 support outer slide 60 towards these diaphragm 30 directions, make the two outer supported terminal parts 31 that are pressed against two diaphragms 30 to post 62 respectively of this outer slide 60, with the 3rd hole 24 and the 4th hole 25 of sealing this body 10, and second hole 23 of this body 10 and the 5th hole 26 are compressed, to form open state, by these first conduit, 27 air inlets, be circulated to this diaphragm 30 inside through the 5th hole 26, be circulated to second penetration hole 22, led to second slotted eye 712 of base plate 70, and by the side gateway 102 of through hole 77 with this cylinder pressure 10 of high pressure air injection, and this cylinder pressure 100 brings out inlet 101 in addition and is exhaust, promptly the through hole 78 of this base plate 70 is scavenging action, and gas is through first penetration hole 21 of base plate 70 the 3rd slotted eye 713 through this body 10, and through this diaphragm 30 of relative position, pass to second conduit 28 toward second hole 23 and discharge, provide this cylinder pressure 100 1 end air inlets to reach, the effect of one end exhaust.

As Figure 13, when switching this cylinder pressure 100, oppositely advance by need, during exhaust, these solenoid valve 80 starts are risen valve rod 82, first through hole 811 is opened, the pressurized gas of first conduit 27 are sent into second through hole 812 by first through hole 811, first hole 20, and by through hole 55 air inlets of interior slide 50 to outer slide 60 grooves 61 (as Figure 11), with the groove 61 that continues air inlet slide 60 in this outside and 50 of slides in this, utilize the pressure of pressurized gas, should be outer slide 60 with should in slide 50 both shore out, make this outer slide 60 outer moving, and compress two elastomers 64, and the 3rd hole 24 and the 4th hole 25 of this body 10 are open state altogether, and should move towards these location piece 40 directions by interior slide 50, to compress two diaphragms 30, make two diaphragms, 30 relative supported terminal parts 31 be closed in second hole 23 and the 5th hole 26 of this body 10, be closed state, 27 air inlets of first conduit are through the 3rd hole 24, through this relative diaphragm 30, be communicated to this first penetration hole 21, enter to base plate 70 the 3rd slotted eye 713, form the air inlet state and be communicated with cylinder pressure 100 gateways 101 by through hole 78, and these cylinder pressure 100 gateways 102 that these base plate 70 through holes 77 connect are exhaust condition, through hole 77 exhausts are through base plate 70 second slotted eyes 712, body 10 second penetration holes 22, can be with gas this diaphragm 30 along relative position, flow to the 4th hole 25, and through 29 discharges of the 3rd conduit, and form complete advancing, exhaust flow path.

As shown in figure 16, when as the use of 3/2 valve type, only need be with behind base plate 70 rotations 180 degree, 10 second of base plate 70 closely connected bodies 12 o'clock, the 3/2 valve type that base plate 70 is the 3rd 73 indicates just can be seen to look by observing window 131 and learns, two elastomers 64 should support towards these diaphragm 30 directions by outer slide 60, make two outer 62 supported terminal parts 31 that are pressed against two diaphragms 30 respectively that prop up of this outer slide 60, with the 3rd hole 24 and the 4th hole 25 of sealing this body 10, and second hole of this body 10 and the 5th hole 26 are compressed, to form open state,, be circulated to this diaphragm 30 inside through the 5th hole 26 by these first conduit, 27 air inlets, to be circulated to this second penetration hole 22, second penetration hole 22 passes to base plate 70 the 4th slotted eye 714, because of the 4th slotted eye 714 is the blind hole position, so air inlet stops.Cylinder pressure 100 inside are provided with the involution of spring 103 as piston 104, air inlet when gateway 101 stops, 104 involutions of spring 103 push piston, make gateway 101 form exhaust, exhaust is via base plate 70 through holes 77, second slotted eye 712, past body 10 first penetration holes 21 are through this diaphragm 30 of relative position, and 23 lead to second conduit 28 along this second hole, second conduit 28 is access to the gateway 102 of cylinder pressure 10 again, gas can be partially recycled, to guarantee to suck not clean gas of outside, erode to spring, and on the other hand, second conduit 28 also is provided with the through hole 281 that is communicated to second 12, this through hole 281 is sealed by base plate 70 when 5/2 valve type, but the 3rd slotted eye 713 of the base plate 70 that when 3/2 valve type, can align.Gas also can be discharged outward by the 3rd slotted eye 713 and through hole 78, uses thereby make cylinder pressure 100 can do exhaust when no air inlet.

As shown in figure 15, after this cylinder pressure exhaust, when need switching the reverse air inlet of this cylinder pressure, this solenoid valve 80 can control first through hole 811 and second through hole 812 is on state, at this moment, as interior slide 50 of being somebody's turn to do of above-mentioned switching valve position and 60 actions of outer slide, be open state with the 3rd hole 24 and the 4th hole 25 with this body 10, and should move towards these location piece 40 directions by interior slide 50, to compress two diaphragms 30, make two diaphragms, 30 relative supported terminal parts 31 be closed in second hole 23 and the 5th hole 26 of this body 10, and after valve position is switched, the 3rd hole 24 and the 4th hole 25 of this body 10 are open state, and second hole 23 of this body 10 and the 5th hole 26 are closed state, 27 air inlets of body 10 first conduits are through the 3rd hole 24 and be communicated to first penetration hole 21 through this relative diaphragm 30 and be air inlet and do the time spent, pressurized gas are by first penetration hole 21, base plate 70 second slotted eyes 712 flow to base plate 70 through holes 77, and be communicated to cylinder pressure 100 gateways 101 because of base plate 70 through holes 77, pressurized gas are able to driven plunger 104 pressure spring 103 simultaneously, make spring 103 side pressure cylinders 100 gateways 102 form exhaust, exhaust is through second conduit 28, through hole 281 and toward base plate 70 the 3rd slotted eye 713, through hole 78 exhausts, and form complete advancing, exhaust flow path.
