Under the action of the 4th resetting apparatus 4-2, that is, pressure spring, the 4th sealed end 4-7 is to the 4th close gas vent of valve chamber 4-8 One end compress, will be sealed between the 4th valve chamber 4-8 and gas vent, push piston 11 to 10 side of snifting valve in piston rod 1 To when movement, after being moved to certain position, the structures such as baffle are provided on piston rod 1, with reset terminal 4-1 far from the 4th sliding bar The side of 4-4 offsets, and drives reset terminal 4-1 and entire 4th spool mobile to 12 direction of inlet chamber, so that the 4th is close Sealing end 4-7 is separated with the 4th valve chamber 4-8, and gas vent is opened, and then the gas in inlet chamber 12 is discharged by gas vent.

It can be seen from the above, the utility model integrates the whole work process of snifting valve 10 are as follows:

Under original state, inlet chamber 12 and jet chamber 7 are vacuum state, and piston 11 is located at middle part, starting driving dress It postpones, piston rod 1 is mobile to 13 direction of intake valve with piston 11, offsets with the first valve rod 13-1, intake valve 13 is opened, will Gas is transported in inlet chamber 12, and communicating valve 5, snifting valve 10 are in off state at this time, and snifting valve 10 is opening state；Work as work After stopper rod 1 is with the movement in place of piston 11, reverse movement, after piston 11 is separated with the first valve rod 13-1, intake valve 13 is closed； When piston 11 continues mobile to 10 direction of snifting valve, inner wall of the second valve rod 5-6 in jet chamber 7 with jet chamber 7 offsets, In During piston 11 is mobile, the second valve rod 5-6 drives the second spool mobile, and communicating valve 5 is opened, and the gas in inlet chamber 12 is logical It crosses communicating valve 5 to enter in jet chamber 7, at this point, intake valve 13, snifting valve 10 are in off state；When piston rod 1 is moved to Position, starts after being moved backward, and the second spool closes communicating valve 5 in the second resetting apparatus 5-2, is further continued for mobile piston 11, Piston 11 drives third valve rod mobile, and snifting valve 10 is opened, and realization sprays the gas in jet chamber 7 from nozzle 8.

The utility model additionally provides a kind of gas ejecting system, as shown in figure 11 comprising the integrated jet of any of the above-described Valve 17.

In the present invention, gas ejecting system includes driving motor 14, transmission mechanism 16, body frame 15 and integrated snifting valve 17, driving motor 14, transmission mechanism 16 and integrated snifting valve 17 are arranged on body frame 15, and driving motor 14 passes through transmission mechanism 16 connect with the piston rod 1 of integrated snifting valve 17, and piston rod 1 is driven to move reciprocatingly.

Integrated snifting valve and gas ejecting system provided by the utility model, are arranged gas in target aircraft, and the gas is logical It crosses intake valve 13 and enters inlet chamber 12, then jet chamber 7 is entered by communicating valve 5, sprayed eventually by snifting valve 10, this When, the gas of ejection charge can damage existing for the surface to target aircraft, that is, destroy its charge balance, realize removal The function of target aircraft surface charge ensure that the normal operation of target aircraft；Its amount of injection is by intake valve 13, connection After 10 3 secondary control of valve 5 and snifting valve, spray volume is smaller, so that use is more long in the case where space is loaded with less gas Time increases the normal working hours of target aircraft.

Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new The range of each embodiment technical solution of type.

In addition, it will be appreciated by those of skill in the art that although some embodiments in this include institute in other embodiments Including certain features rather than other feature, but the combination of the feature of different embodiment means to be in the utility model Within the scope of and form different embodiments.For example, embodiment claimed is appointed in claims above Meaning one of can in any combination mode come using.The information disclosed in the background technology section is intended only to deepen to this The understanding of the general background technology of utility model, and be not construed as recognizing or implying in any form that information composition has been The prior art known in those skilled in the art.
