Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

One side of valve body 7 has suction port P and relief opening R1, the R2 that communicates with valve pocket respectively, and the opposite side of valve body 7 is provided with gas delivery port A, K.As shown in Figure 1, 2, 3.

Gas control covers and copper sheathing 13 is installed in 16 cross through hole and is with the moving iron core 18 of boring spring 15 and having rubber cushion 14 with the end, and moving iron core 18 is slided with copper sheathing 13 and joined installation.Gas control covers the hand lever 3 that the band seal ring is installed in the 16 upper end through holes, locks hand lever 3 with locating stud 23, and hand lever 3 lower ends are semicolumn jaggy.Pressing plate 2 is screwed on gas control lid 16, and coil 1 is enclosed within on the moving iron core 18.

Forward and backward

lid

17,12 is screwed on the front and rear end of valve body 7, is provided with piston 5 in protecgulum 17, and piston 5 is provided with y-shaped ring 4.Be provided with spring 11 between bonnet 12 and the valve rod 9 end blind holes.

Seal ring is combination shape seal ring 10, by inserting spacer 8 location between 6 combination shape seal rings 10 and adjacent two O-ring seals 10, places in the valve body 7 to cooperate with valve rod 9, and by valve body cover plate 6 location.As shown in Figure 1.

It is the bilateral ring of band muscle, through hole that spacer 8 becomes periphery by plastic production, and flange is arranged on the both ends of the surface.

Ring groove on O RunddichtringO 10 both ends of the surface cooperates with the flange of spacer 8 both ends of the surface centre.

Valve body horizontal stroke, straight air flue 24,25 communicate with valve pocket and suction port P, and the protecgulum horizontal stroke that is provided with protecgulum 17, directly

air flue

22,21 communicates.Valve body horizontal stroke, straight air flue 24,25 and gas delivery port A, K be not in same plane.Shown in Fig. 4,5.

Gas enters valve body 7 from suction port P, flow to protecgulum horizontal stroke,

straight air flue

22,21 by valve body horizontal stroke, straight air flue 24,25, meanwhile, coil 1 energising attracts moving iron core 18 compression cone springs 15 to move in copper sheathing 13, and open the pilot head 19 that gas control covers 16 places, at this moment gas enters valve body 7 from the pore 20 on the protecgulum 17, and promotion piston 5 drive valve rods 9 move right, at this moment enter valve body 7 from suction port P, give the workpiece air feed through gas delivery port A again, gas delivery port K mouth is blocked, and gas can't flow out, and discharges gas through relief opening R2 simultaneously.As shown in Figure 5.

When the powered-down coil does not have electricity, moving iron core 18 is resetted by volute spring 15 and seals the pilot head 19 that gas control covers 16 places, and spring 11 drive valve rods 9 reset simultaneously, and at this moment gas delivery port A closes, give the workpiece air feed by gas delivery port K, discharge gas through relief opening R1 simultaneously.Unnecessary gas in the protecgulum 17 is discharged from netted gas port 26.

The solenoid valve at this moment available manually-operable of not working when not having electricity, manual rod 3 revolved turn 90 degrees, hand lever 3 is thrown off locating stud 23, the semicolumn of its lower end backs down moving iron core 18 compression cone springs 15 moves iron core 18 direction in copper sheathing 13, at this moment gas just enters protecgulum 17 and promotes piston 5 drive valve rods 9 from pore 20 and moves right, concrete working procedure is same as described above, no longer repeats.
