Embodiment Construction

[0033] The present case will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as Figure 4 Shown is the release control system of a dry powder fire extinguishing equipment involved in this case. Herein, the dry powder fire extinguishing equipment with the fire extinguishing release control device mentioned in the background art will be described in detail.

[0035] Dry chemical fire extinguishing equipment with extinguishing release controls such as Figure 1-3 As shown, it includes a system startup bottle 1, a high-pressure gas storage bottle 2, a release control device 3 and a dry powder storage tank 4. The high-pressure gas cylinder 2 is connected to the dry powder storage tank 4 through the gas collecting pipe 51 . The release control device 3 is connected between the system startup bottle 1 and the high-pressure gas storage bottle 2 .

[0036] release control device 3 such as figure 2 As shown...

Abstract

The invention discloses a release control system of dry powder fire extinguishing equipment, which includes a parallel system start module, a release start module and a release control module; the system start module has a parallel first relay and a system start bottle solenoid valve, and a system start bottle The normally open switch of the first relay is connected in series on the branch where the solenoid valve is located; the release start module includes an electric contact pressure unit, a dry powder release solenoid valve and a second relay, the dry powder release solenoid valve and the second relay are connected in parallel, and the electric contact pressure unit It is connected in parallel with the moving contact of the second relay, and the two parallel branches are connected in series; the release control module has a pressure switch, a normally open solenoid valve and a normally closed solenoid valve, and the normally open solenoid valve and the normally closed solenoid valve are connected in parallel Then connect it in series with the pressure switch. The invention achieves precise control and keeps the release pressure of the dry powder storage tank constant, the dry powder is sprayed evenly, and the fire extinguishing effect is improved.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing equipment, in particular to a release control system of dry powder fire extinguishing equipment. Background technique [0002] The existing dry powder fire extinguishing system mainly includes a dry powder tank, a high-pressure nitrogen bottle and a nitrogen starter bottle. The nitrogen starter bottle starts the high-pressure nitrogen bottle, the high-pressure nitrogen bottle is opened, and the high-pressure gas is filled into the dry powder tank through the gas collecting pipe to realize Extinguishing agent is released and sprayed out. The air pressure control in the dry powder tank during work is very critical. Too high air pressure will cause safety hazards such as tank explosion. At present, to solve this problem, the protective measures taken are to install relevant explosion-proof mechanism on the dry powder tank. When the pressure in the dry powder tank is detected to be too hig...
