Description of drawings
Fig. 1 is a pipeline connecting figure of the present utility model
The specific embodiment
A kind of low pressure that is used for is controlled the jack unit that discharges Compressed Gas automatically, comprise auto-pneumatic cylinder 14 and switch board 16, the input that it is characterized in that pneumatic ball valve 2 is connected with gas cylinder group 17, the output of pneumatic ball valve 2 is connected with auto-pneumatic cylinder 14, the control end of pneumatic ball valve 2 is provided with magnetic slide valve 15, gas cylinder group 17 is connected by the input of pipeline with magnetic slide valve 15, the output of magnetic slide valve 15 is connected with the control end of pneumatic ball valve 2, and the control end of magnetic slide valve 15 is connected with switch board 16 by control line.Gas cylinder group 17 is connected with the input of the 3rd ball valve 3, and the output of the 3rd ball valve 3 is connected with the input of pneumatic ball valve 2, and the output of pneumatic ball valve 2 is connected with the input of first ball valve 1, and the output of first ball valve 1 is connected with auto-pneumatic cylinder 14 by tracheae 13.Gas cylinder group 17 also is connected with the input of the 4th ball valve 4 by safety valve 5, and the output of the 4th ball valve 4 also is connected with auto-pneumatic cylinder 14 by tracheae 13.Gas cylinder group 17 is connected with the input of the 5th ball valve 7, and the output of the 5th ball valve 7 is connected with an end of rubber tracheae 12 by pressure-reducing valve 6, and the other end of rubber tracheae 12 is connected with the input of magnetic slide valve 15.The output of the 5th ball valve 7 also is connected with electro connecting pressure gauge 10 by gauge valve 9, also be provided with magnetic valve 8 between the 5th ball valve 7 and the gauge valve 9, the input of magnetic valve 8 is connected with the 5th ball valve 7, the output of magnetic valve 8 is connected with extraneous, and the control end of the control end of magnetic valve 8 and electro connecting pressure gauge 10 all is connected with switch board 16 by control line.One end of tracheae 13 is connected with auto-pneumatic cylinder 14, and the other end of tracheae 13 is provided with the 6th ball valve 11, is used for manual exhaust and simulation fire-fighting signal.
As shown in the figure, under duty at ordinary times, the high pressure compressed gas that discharges from gas cylinder group 17 is through the pressure-reducing valve group fire-fighting work pressure state that reduces pressure, and enters originally to install pipes.Because the magnetic slide valve 15 of configuration is all cutting out under the duty at ordinary times on the 4th ball valve 4, pneumatic ball valve 2 and the pneumatic ball valve 2, so Compressed Gas can not enter auto-pneumatic cylinder by this device.
When the condition of a fire occurring, the emergent fire fighting water work switch board of gas roof pressure receives the fire-fighting signal, magnetic slide valve 15 on the switch board control pneumatic ball valve 2 is opened, enter the cylinder of pneumatic ball valve 2 through the logical rubber tracheae 12 of pressure-reducing valve 6 post-decompression Compressed Gas, the promotion pneumatic ball valve is opened, Compressed Gas enters auto-pneumatic cylinder through air inlet pipe 13, the fire demand water in the auto-pneumatic cylinder is ejected the fire-fighting of meeting an urgent need.
When being the maintenance pneumatic ball valve, first ball valve 1, the 3rd ball valve 3 and the 4th ball valve 4 use;
Under duty at ordinary times, the pressure of the ducted Compressed Gas of whole jack unit is fire-fighting work pressure, and the pressure that driving pneumatic ball valve 2 is opened is 0.4MPa, therefore when fire-fighting work pressure is higher than 0.4MPa, just need pressure-reducing valve 6 the 0.4MPa that reduces pressure of the compression pressure in the jack unit;
The 5th ball valve 7 is to use when keeping in repair pressure-reducing valve 6, magnetic valve 8 with replacing rubber tracheae 12;
10 usefulness when gauge valve 9 is maintenance and replacing electro connecting pressure gauge;
The 6th ball valve 11 is to be used for manual exhaust and simulation fire-fighting signal;
When the pressure in originally installing pipes reached the upper pressure limit that electro connecting pressure gauge 10 sets, magnetic valve 8 was opened and is carried out that pressure release and safety valve 8 prevent jointly that gas cylinder pressure-reducing valve group may lose efficacy and hypertonia in causing originally installing pipes, the starting double protection.
