The specific embodiment
As shown in Figure 1; A kind of gas roof pressure of the utility model fire water supply equipment; Comprise electric-control system, jack unit, stable-pressure device, auto-pneumatic cylinder 3, air-stopping valve 14, collection assembling device; Said jack unit comprises High-Pressure Compressor 9, gas cylinder group 7, roof pressure valve 11, and said High-Pressure Compressor 9 links to each other with gas cylinder group 7 through pressure duct 8, and said gas cylinder group 7 links to each other with roof pressure valve 11; Said stable-pressure device links to each other with roof pressure valve 11, and said roof pressure valve 11 links to each other with auto-pneumatic cylinder 3 through roof pressure pipeline 4; Said auto-pneumatic cylinder 3 is provided with magnetic sheet content gauge 1, and said magnetic sheet content gauge 1 is provided with three liquid level contacts, is followed successively by voltage stabilizing water contact 19, replacing water contact 20, protection water contact 21 from top to bottom; Said auto-pneumatic cylinder 3 lower ends link to each other with air-stopping valve 14 through pipeline; Be connected with the collection assembling device on said auto-pneumatic cylinder 3 and the pipeline that air-stopping valve 14 is connected; Said collection assembling device is that some small pumps 17 are formed in parallel, and the pipeline of said small pump 17 parallel connections is provided with pressure transmitter 16; Said air-stopping valve 14 links to each other with roof pressure valve 11 through low pressure gas circuit 13, and said air-stopping valve 14 other ends are connected with flap valve 15 through pipeline, and said flap valve 15 is connected with fire_fighting pipe network 18; Said electric-control system is the switch board 5 of running whole system, and said switch board 5 links to each other with the various piece of said gas roof pressure fire water supply equipment through holding wire 6.
