Testing apparatus of high-pressure water mist system

Abstract

The invention discloses a testing apparatus of a high-pressure water mist system. The testing apparatus comprises a high-pressure water mist pump set, the high-pressure water mist pump set is connected with the high-pressure water mist system, the water outlet end of the high-pressure water mist pump set communicates with a water inlet side high-pressure ball valve in a valve box through a water inlet pipe, the water inlet side high-pressure ball valve sequentially communicates with a high-pressure electric ball valve and a water outlet side high-pressure ball valve, the water outlet side high-pressure ball valve is connected with a test high-pressure water mist spraying head for testing through a water outlet pipe, a control box is arranged in the valve box, and the high-pressure electricball valve is in circuit connection into the control box. The running condition of the high-pressure water mist system can be tested at any time conveniently, the fireproof risk caused by equipment failures can be reduced, stability and application of the high-pressure water mist system can be improved, an operation department can conveniently repair or replace equipment accessories in time, andit is ensured that the high-pressure water mist system can be normally started under the fire condition.

Description

technical field [0001] The invention belongs to the field of rail transit security, and in particular relates to a test device for a high-pressure fine water mist system. Background technique [0002] In recent years, with the construction of a large number of urban rail transit projects, the safety of the subway has been paid more and more attention. The current subway disaster prevention and relief means and technologies are relatively limited and cannot meet the actual needs of subway safety. As the electrical equipment room most likely to cause fire in the subway, most rail transit in China is still protected by heptafluoropropane (FM200) or inert gas (IG541) gas fire extinguishing system. However, the gas fire extinguishing agent is expensive and easy to leak, and the construction investment and operation costs are high. More importantly, the efficiency of the gas fire extinguishing system is very low, and the misspray of the system may easily cause casualties, so the ...
