Summary of the invention
The utility model is accomplished in order to solve deficiency of the prior art; The purpose of the utility model provides can automatically regulating cabin internal pressure, and the existence cabin of the band S. A. differential pressure adjusting device of can also be manually under the situation that self-checking device lost efficacy the cabin internal pressure being regulated.
The existence cabin of the band S. A. differential pressure adjusting device of the utility model; Comprise cabin body and the dividing plate that is positioned at the cabin body; Said dividing plate is divided into leak free transition module and fully enclosed master cabin with the cabin body; Be provided with the pressure test device that detects external boundary, cabin and said main cabin internal pressure differences in the said main cabin, automatic decompression device and manual pressure relief device are set on the said dividing plate, said automatic decompression device is connected said transition module and is provided with check valve with the extraneous wall that contacts with said pressure test device.
The existence cabin of the band S. A. differential pressure adjusting device of the utility model can also be:
Be provided with alarm device in the said pressure test device.
Said pressure test device is provided with cabin internal pressure detector tube and pressure detection pipe out of my cabin, and internal pressure detector tube end, said cabin is arranged in the said main cabin, said pipe of pressure detection out of my cabin and air communication out of my cabin.
Said automatic decompression device is the pulsed automatic decompression valve.
Said manual pressure relief device comprises ball valve.
The existence cabin of the band S. A. differential pressure adjusting device of the utility model; It comprises cabin body and the dividing plate that is positioned at the cabin body; Said dividing plate is divided into leak free transition module and fully enclosed master cabin with the cabin body; Be provided with the pressure test device that detects external boundary, cabin and said main cabin internal pressure differences in the said main cabin, automatic decompression device and manual pressure relief device are set on the said dividing plate, said automatic decompression device is connected said transition module and is provided with check valve with the extraneous wall that contacts with said pressure test device.Like this; In terms of existing technologies since automatic decompression device can according to value preset in the pressure test device and actual measurement to the unlatching of pressure differential value or close automatic decompression device; Guarantee the suitable pressure reduction of the inside and outside maintenance in cabin, and after automatic decompression device damaged, can operate manual pressure relief device carried out manual pressure release; Alleviated personnel's pressure in the cabin, monitored pressure test device always without it.

The specific embodiment
Fig. 1 below in conjunction with accompanying drawing does further explain to the existence cabin of the band S. A. differential pressure adjusting device of the utility model.
The existence cabin of the band S. A. differential pressure adjusting device of the utility model; Please refer to Fig. 1; Comprise cabin body 1 and the dividing plate 2 that is positioned at cabin body 1; Said dividing plate 2 is divided into leak free transition module 3 and fully enclosed master cabin 4 with cabin body 1; Be provided with the pressure test device 5 that detects cabin body 1 external world and said main cabin 4 internal pressure differences in the said main cabin 4, automatic decompression device 6 and manual pressure relief device 7 are set on the said dividing plate 2, said automatic decompression device 6 is connected said transition module 3 and is provided with check valve 8 with the extraneous wall that contacts with said pressure test device 5.Like this; In terms of existing technologies since automatic decompression device 6 can according to values preset in the pressure test device 5 and actual measurement to the unlatching of pressure differential value or close automatic decompression device 6; Guarantee the suitable pressure reduction of the inside and outside maintenance in cabin, and after automatic decompression device 6 damaged, can operate manual pressure relief device 7 carried out manual pressure release; Alleviated personnel's pressure in the cabin, monitored pressure test device 5 always without it.
The existence cabin of the band S. A. differential pressure adjusting device of the utility model please refer to Fig. 1, specifically can be to be provided with alarm device in the said pressure test device 5.Like this when the inside and outside pressure in cabin reaches predetermined critical value; Be automatic decompression device 6 off positions this moment; Can sound alarm and flash Warning light of alarm device, prompting cabin external and internal pressure difference is in critical conditions, need close or open or turn down or open big manually pressure relief device 7; Regulate the inside and outside difference of pressure in cabin within preset range, guarantee the personnel's in survival capsule or the existence cabin safety.
The existence cabin of the band S. A. differential pressure adjusting device of the utility model; Please refer to Fig. 1; Can also be to be provided with cabin internal pressure detector tube and pressure detection pipe out of my cabin on the said pressure test device 5 on the basis of technique scheme; Internal pressure detector tube end, said cabin is arranged in the said main cabin 4, said pipe of pressure detection out of my cabin and air communication out of my cabin.Like this, the difference of pressure inside and outside the cabin that can guarantee to measure is more accurate, can not cause unnecessary harm.
