Technical field
The utility model relates to fire-fighting equipment technical fields, and in particular to be a kind of fire-fighting network management with exhaust structure System.
Background technique
Existing fire system includes fire cistern and fire-fighting region, and connection fire cistern leads to the fire-fighting in fire-fighting region Pipeline is equipped with pumping equipment on fire protection pipeline.Such as electric-drive fire pump and diesel powered fire pump.Diesel powered fire pump is electronic Fire pump provides emergency water supply in the case where failing, and guarantees to play its emergency function when fire occurs, ensures the people's with this Property and personal safety, therefore the safety and reliability of equipment is particularly important.Diesel powered fire pump is typically mounted at extinguishing pipe Lead to fire-fighting region on road, non-return valve is generally all installed in the water outlet of usual diesel powered fire pump, and non-return valve main function is It prevents the high hydraulic pressure in fire protection pipeline from flowing back to industrial fire pond by fire pump, is generally also equipped with multiple pipes on fire protection pipeline Road valve.
However, fire protection pipeline is easily mixed into air, the water outlet of diesel powered fire pump is caused to spray inability or operational failure.Study carefully Its reason deposits main following two aspect: the ring flange of pipeline valve and sealing for tubing joints be not close on one side fire protection pipeline, when When diesel powered fire pump works, it is easy sucking air.Finally, it hoards in the pump chamber of diesel powered fire pump.On the other hand, due to Non-return flap service wear and aging, lead on non-return flap that valve flange plate is not tight with tube body, cause the high hydraulic pressure of water fire protection pipeline Industrial fire pond is flowed back to by fire pump.When high pressure water is retracted toward fire protection pipeline low pressure water in fire protection pipeline, bubble can be generated, It for a long time can be in the pump chamber of electric-drive fire pump and diesel powered fire pump lining product air.
In consideration of it, inventor furthers investigate, there is this case generation then.
Utility model content
The fire-fighting network management system with exhaust structure that the purpose of this utility model is to provide a kind of, can be effectively by fire-fighting Pump in gas discharge, guarantee fire pump can normal pumping work, convenient for effectively fire extinguishing, reduce property loss.
In order to achieve the above objectives, the solution of the utility model is:
A kind of fire-fighting network management system with exhaust structure, including fire cistern and fire-fighting region, and connection fire water Lead to the fire protection pipeline in fire-fighting region in pond, and fire pump is equipped on the fire protection pipeline, and the fire protection pipeline includes the first branch Pipeline and second branch pipeline, the fire pump include the first fire pump and the second fire pump, and first fire pump is installed on On the first branch pipeline, second fire pump is installed on the second branch pipeline, the first branch pipeline and The second branch pipeline respectively leads to the corresponding fire-fighting region, and first fire pump and the second fire pump respectively include Ontology is pumped, is respectively equipped with the chamber that draws water on the pump ontology, structure identical first is separately installed on the pump ontology automatically Exhaust apparatus and the second automatic exhaust device, the inlet end of first automatic exhaust device are connected to the pumping of first fire pump The top of water chamber, the inlet end of second automatic exhaust device are connected to the top of the chamber that draws water of second fire pump.
Preferably, first automatic exhaust device includes exhaust nozzle, sphere, upper cover, lower case, and the lower case has Cavity for accommodating the sphere and bouncing in the lower case for the sphere, the sphere are located in the cavity, The upper cover is sealed through screw locking in the lower case and by the recess of the cavity, has gas vent on the upper lid, The exhaust nozzle is removably mounted on the gas vent, and the cavity bottom is provided with inside and outside the connection lower case Channel, the diameter of the sphere not less than the passway in the channel bore, through paper washer between the upper cover and lower case Piece sealing.
Preferably, on the first branch pipeline between first fire pump and the corresponding fire-fighting region Part be laid with for on the second branch pipeline between second fire pump and the corresponding fire-fighting region Part connection the first connecting tube.
Preferably, the fire protection pipeline further includes third bypass line, and gas supply dress is equipped in the third bypass line It sets, the third bypass line and feeder ventilation connect, and the feeder is located in the third bypass line Part between the fire-fighting region is connected with two second connecting tubes, and two second connecting tubes are respectively with described first Part and the second branch pipeline in bypass line between first fire pump and the corresponding fire-fighting region The upper part between second fire pump and the corresponding fire-fighting region is connected, in two second connecting tubes It is respectively mounted first pipe valve.
