Preferably, described suction chamber is provided with the gas access, and described exhaust chamber is provided with gas outlet, and described gas switches the chamber and is provided with gas inlet-outlet.
Preferably, the described suction chamber and first sealed chamber are positioned at valve body lower portion, and the described exhaust chamber and second sealed chamber are positioned at valve body top.
Further, described gas access is an exhaust gas entrance, and described gas outlet is clean gas outlet, and described gas inlet-outlet is waste gas outlet and clean gas inlet simultaneously.
Further, the cavity cross section of described first sealed chamber is up-small and down-big, and the cavity cross section of described second sealed chamber is up big and down small.
Further, also comprise a final controlling element, described final controlling element is connected the valve rod upper end.
Hermetic seal formula poppet valve of the present utility model by sealed chamber is set, and is provided with the pressurized gas interface on sealed chamber, form a circle air curtain by the high-pressure blast that blows into sealed chamber from this interface, stop internal gas outwards to be revealed, can reach efficient sealed effect, reduce leak-down rate.

Fig. 3 is the structural representation when general who has surrendered's first passage seals under the valve plate.
Embodiment
Below in conjunction with accompanying drawing scheme of the present utility model is further specified.
As shown in Figure 1, hermetic seal formula poppet valve of the present utility model is long housing structure, promote vertically and arrange, comprise valve rod 12, valve body, be connected the final controlling element 13 of valve rod 12 upper ends, be connected the valve plate 11 of valve rod 12 lower ends, valve body is provided with suction chamber 1 and exhaust chamber 5, suction chamber 1 is provided with gas access 6, exhaust chamber 5 is provided with gas outlet 10, comprise that also the gas of being located between suction chamber 1 and the exhaust chamber 5 switches chamber 3, gas switches chamber 3 and is provided with gas inlet-outlet 8, valve plate 11 is positioned at gas and switches chamber 3, be provided with first passage 14 between suction chamber 1 and the gas switching chamber 3, be provided with second channel 15 between exhaust chamber 5 and the gas switching chamber 3, also be provided with first sealed chamber 2 and second sealed chamber 4 on the valve body, first sealed chamber 2 is positioned at around the first passage 14, second sealed chamber 4 is positioned at around the second channel 15, the suction chamber 1 and first sealed chamber 2 are positioned at valve body lower portion, the exhaust chamber 5 and second sealed chamber 4 are positioned at valve body top, first sealed chamber 2 is arranged on around the first passage 14, second sealed chamber 4 is arranged on around the second channel 15, the cavity cross section of first sealed chamber 2 is up-small and down-big, the cavity cross section of second sealed chamber 4 is up big and down small, promptly first sealed chamber 2 is less near the cavity cross section that gas switches chamber 3, second sealed chamber 4 is also less near the cavity cross section that gas switches chamber 3, to guarantee better hermetic seal effect.First sealed chamber 2 is provided with the first pressurized gas interface 7, second sealed chamber 4 is provided with the second pressurized gas interface 9, wherein valve plate 11 moves up and down, and is used for gas being switched second channel 15 sealings between first passage 14 between chamber 3 and the suction chamber 1, gas switching chamber 3 and the exhaust chamber 5 or opening.
In Fig. 1, gas access 6 is an exhaust gas entrance, and gas outlet 10 is clean gas outlet, and gas inlet-outlet 8 is waste gas outlet and clean gas inlet simultaneously.
Working principle of the present utility model is as follows: promote when final controlling element 13 drives valve rod 12, when making valve plate 11 rise to second channel 15, with these second channel 15 sealings, this moment, waste gas entered into suction chamber 1 by exhaust gas entrance 6, meanwhile, be blown into pressurized gas by the second pressurized gas interface 9, enter into second sealed chamber 4, form a circle hermetic seal at second channel 15 places, stop waste gas to be revealed to second sealed chamber 4, cause all waste gases to pass first passage 14 and gas switching chamber 3, all discharge by waste gas outlet 8.In like manner, when driving valve rod 12, final controlling element 13 descends, when making valve plate 11 fall to first passage 14, these first passage 14 sealings, clean gas enters into gas by clean gas inlet 8 and switches chamber 3, meanwhile, be blown into pressurized gas, enter into first sealed chamber 2 by the first pressurized gas interface 7, form a circle hermetic seal at first passage 14 places, stop clean gas to be revealed, cause all clean gas to pass second channel 15 and exhaust chamber 5, all discharge by clean gas outlet 10 to first sealed chamber 2.Wherein may command periodically enters first or second sealed chamber by this two interface from the high-pressure blast that the first pressurized gas interface and the second pressurized gas interface enter, and control valve plate 11 move up and down at gas with switching indoor 3 intercycles, first passage 14 or second channel 15 are sealed or are opened.
