SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model aims at providing a ventilation system for gas cylinder safety cabinet that ventilation effect is good, possesses automatic alarm and detects the function.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a ventilation system for gas cylinder safety cabinet, including setting up the gas cylinder cabinet in the fume chamber, and set up in the fume chamber, the relief pressure valve of being connected with the gas cylinder cabinet, including gas cylinder in the gas cylinder cabinet, and the pressure relief device who meets with gas cylinder, and the solenoid valve that meets with pressure relief device, and the flow monitoring table that meets with the solenoid valve, still be equipped with gas leakage alarm device in the gas cylinder cabinet, gas leakage alarm device has connect the alarm, the gas cylinder cabinet is last to be opened there is the vent, the relief pressure valve is connected with the flow monitoring table.
Preferably, the pressure reducing device comprises a gas bottle pressure reducing valve and a parameter table assembled on the gas bottle pressure reducing valve.
Furthermore, more than one gas bottle is arranged and is respectively connected to the pressure reducing device.
Preferably, the pressure reducing device is a detachable base plate arranged in the fume hood, more than one gas bottle pressure reducing valves arranged on the base plate and a parameter table matched with the gas bottle pressure reducing valves one by one.
Furthermore, be equipped with the flabellum in the vent, alarm and the interior flabellum of vent adopt electric connection.
Furthermore, the pressure reducing valve is provided with more than one pressure reducing valve and is respectively connected with the flow monitoring meter.
Preferably, the gas leakage alarm device is provided with more than one gas leakage alarm device and is respectively connected to the alarm devices.
Preferably, the alarm is a buzzer alarm.
The utility model has the advantages that:
through the design that adopts the gas cylinder cabinet, the pressure relief device who meets with the gas cylinder in the gas cylinder cabinet, solenoid valve and flow carry out gaseous flow monitoring, when gas flow surpassed the threshold value of settlement, the solenoid valve is closed, and start alarm and the intraoral flabellum of vent, exhaust and close the valve, on the other hand when the condition of leaking appears in the gas cylinder, gas leakage alarm device detects after gaseous, feedback to alarm start-up alarm, the alarm is after starting the alarm, feedback simultaneously to the intraoral flabellum of vent and exhaust the operation and close the valve.
