Stop valve

18 and 24 has corresponding structure.Therefore, first stop valve 18 is corresponding with second stop valve 24 to have the first film 51 and second film 52 equally, the latter define the valve chamber 62 of valve housing 66 and with respect to this shell by supporting as this spring 71 of helical spring.First and

second films

51,52 connect by picture tappet 58 this stiffeners.

Also have corresponding structure in second stop valve 24, that is to say, the supporting element 120 of second film 56 or plate-like just supports by spring 72 with respect to this bottom with respect to valve housing 68.The

spring

71,72 of

stop valve

18,24 is effect so in this regard, makes

stop valve

18,24 make great efforts changing-over to fastening position (Fig. 1), that is to say, makes pipeline or manages 10 or 14 sealings.

In order to operate suction rifle 12, be provided with control valve 22, it has the release 20 that is connected with valve tappet 122 as the button formation, and control valve 22 can switch by valve tappet.Valve tappet 122 supports like this by spring 124, makes control valve 22 make great efforts to switch to fastening position.

From managing 14 introduction pipes 78, the inside is provided with one way valve 125.Pipeline 78 leads to first interface 126 of control valve 22 on the one hand by branch road 81, lead to second interface 127 of control valve 50 on the other hand.

In addition, from control valve 20 introduction pipes 76, it leads to pipeline 70 by one way valve 74, and the latter is connected on the one hand with by the shell 66 of first stop valve 18 and the valve chamber 62 of second film, 52 qualifications, leads to first interface 72 of control valve 50 on the other hand.In addition, the pipeline 76 of drawing from control valve 22 feeds in first interface 80 of release control valve 34.

Be distributed in first interface 72 and the pipeline between the valve chamber 62 70 of control valve 50 and so also have valve chamber 62 to blow by the opening 94 in nozzle 92 in the pipeline 70 and control valve 50 shells 95.The valve chamber 64 of second stop valve 24 correspondingly also can be by nozzle 96 air-supplies.Same method also is applicable to can be by the valve chamber 82 of nozzle 98 air-supplies as the bypass valve 46 of diaphragm valve formation.

Control valve 50 has two valve discs 73,75, by them under the situation that depends on control valve 50 valve tappets 77 positions, on the one hand first and second interfaces 72,127 seals mutually, just valve disc 75 sealings be close to respective valve seat and therefore opening 94 pass through under first interface 72 and the situation that pipeline 70 is connected.On the other hand, on the position that control valve 50 is opened, valve disc 73 is close on another valve seat, thus opening 94 with respect to the blocking-up of first interface 72, but first and second interfaces 71,127 connect.On this open position of control valve 50, the valve chamber 62 of stop valve 18 applies low pressure.

Release control valve 34 is connected with the valve chamber 82 of bypass valve 46 by the pipeline 128 on its second interface 84.

Do not connecting under the situation of suction rifle 16 (Fig. 1), diaphragm valve, just first and

second suction valves

18,24 and bypass valve 46 are closed.If suction rifle 16 is connected (Fig. 2) by Kamlock-hookup mechanism 12 with the collection container of want emptying, tappet 32 is moved to the left in this diagram so, thereby release control valve 34 is opened (Fig. 2), and just first and

second interfaces

80,84 connect.Control valve 50 switches simultaneously, just opens, and that is to say that first and second interfaces 72,126 connect equally.Therefore, by pipeline 78, branch road 81 and control valve 50 by opening, second and

first interface

127,72 just, low pressure enters valve chamber 62, opens stop valve 18 and the first film 51 on-tubes 14 thus thus.Simultaneously, therefore opening 94 also also has valve disc 73 blocking-up of pipeline 70 by control valve 50 with respect to first interface 72.

If now to control valve 22 pressurizations, just make to form between its interface 126,131 and connect, the vacuum that is in so in the suction tube 14 continues to enter the valve chamber 82 of bypass valve 46 by pipeline 78, control valve 22, pipeline 76, release control valve 34, thus this valve open.

By opening bypass valve 46, the low pressure that is in the suction tube 14 continues to enter the valve chamber 64 of second stop valve 24 by

interface channel

42,44, thus this valve open.

If aspiration procedure finishes, pass through release button 20 closed control valves 22 so, thereby thus in situation lower valve chamber 82 air-supplies of depending on nozzle 98 cross sections, and therefore bypass valve 46 cuts out over time, second stop valve 24 is closed then by nozzle 96 air-supplies thus.If hookup mechanism 12 is thrown off suction rifle 16, release control valve 34 is closed so.Only the air port arm 104 of inner part 28 is pulled out from exterior part 26 fully with suction channel 14 in low pressure disconnect after, control valve 50 just cuts out.By the consequent time-delay of closing of stop valve 18, can reliably aspirate the residual liquid that is in hookup mechanism 12 zones, thus the danger that can not occur polluting.

If vehicles side does not have stop valve 24, the exterior part 26 of hookup mechanism 12 does not have annular lip 38 so, thereby tappet 32 can not move when connecting suction rifle 16.But, can come pumping liquid by suction rifle 16 with replacing; Because connect the interface 126,131 of control valve 22 by action button 20, thereby by

pipeline

78,76 and one way valve 74 and can enter the valve chamber 62 of stop valve 18 then equally by pipeline 70 low pressure, thereby stop valve 18 is opened and is discharged suction channel 14 thus.
