Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an enlarged view of the area a in fig. 1.
Detailed Description
As shown in fig. 1-2, high temperature resistant air cannon, including gas holder 1, be fixed with the intake pipe 16 rather than the intercommunication on the gas holder 1, be fixed with the neck 3 rather than the intercommunication on the gas holder 1, blast pipe 2 runs through gas holder 1 and extends to in the neck 3, blast pipe 2 and 1 fixed sealing connection of gas holder, 3 end fixing of neck have flange ring 4, fixed sealing connection has shrouding 5 on the flange ring 4, be fixed with elasticity membrane bowl 9 between flange ring 4 and the shrouding 5, elasticity membrane bowl 9 seals 2 one end of blast pipe in the neck 3, be fixed with quick discharge valve 11 on the shrouding 5, space intercommunication between quick discharge valve 11 and elasticity membrane bowl 9 and the shrouding 5.
8 left ends of mounting is fixed with sealed pad 10, and mounting 8 is through sealed pad 10 and 2 right-hand members sealing contact of blast pipe, sealed pad 10 is sealed the pad for high temperature resistant, has seted up restricted aperture 14 on the toper ring 7, and 8 right-hand member circumference equipartitions of mounting are fixed with a plurality ofly and its vertically inserted bar 13, and 5 left ends of shrouding are fixed with the sleeve pipe 12 that corresponds with inserted bar 13, and inserted bar 13 extends to in the sleeve pipe 12 and rather than sliding fit.
When the utility model is used, high-pressure gas enters the gas storage tank 1 through the gas inlet pipe 16, the high-pressure gas enters the space between the elastic membrane bowl 9 and the seal plate 5 through the flow limiting valve 14, at the moment, the air pressure in the space between the neck pipe 3, the gas storage tank 1 and the elastic membrane bowl 9 and the seal plate is equal, the elastic membrane bowl 9 seals one end of the exhaust pipe 2 in the neck pipe 3 by the force elasticity of the elastic membrane bowl 9, during the work, the quick exhaust valve 11 is opened, the gas in the space between the elastic membrane bowl 9 and the seal plate 5 is quickly exhausted, the gas in the gas storage tank 1 can not enter the space between the elastic membrane bowl 9 and the seal plate 5 in time under the flow limiting effect of the flow limiting hole 14, in the process, pressure difference can be generated in the space between the gas storage tank 1 and the elastic membrane bowl 9 and the seal plate 5, at the moment, the seal piece 8 moves to the right side under the effect of the pressure in the gas storage tank 1, the, after 2 one end of blast pipe in the neck 3 is opened, 1 air pressure energy of gas holder is changed into air jet power energy and is discharged from blast pipe 2, thereby produce powerful impact force, gas in the gas holder 1 is discharged the back, carry out the shutoff once more to blast pipe 2 after the mounting of elastic membrane bowl 9 is restoreed, along with the continuous entering into gas holder 1 of compressed air, the gas of gas holder 1 enters into the space between elastic membrane bowl 9 and shrouding 5 through restricted aperture 14 once more, make the pressure balance in the space between gas holder 1 and elastic membrane bowl 9 and the shrouding 5, prepare for next start-up. When the sealing piece 8 of the elastic membrane bowl 9 moves towards the right side, under the matching action of the inserted rod 13 and the sleeve 12, the sealing piece 8 can move towards the direction of the sealing plate 5 in parallel, so that the conical ring 7 can be deformed integrally, the phenomenon that the fatigue strength of a certain part of the sealing piece 8 is reduced and the sealing piece 8 is damaged due to long-time unilateral movement during starting can be prevented, and the service life of the elastic membrane bowl 9 is ensured.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
