The utility model organically combines the control of main valve and foam solution control valve, just can open main valve and foam solution control valve simultaneously by the main valve control piper, both save the automatically controlled requirement of foam solution pipeline, increased the reliability of system, also can reduce the cost of system's control circuit.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Embodiment one
The universal foam of the present embodiment control valve group that drenches with rain comprises main valve 3 and the foam solution control valve 7 that is placed in the casing 11.The entrance point of main valve 3 connects the water supply connector 1 that is connected with system water inlet pipe network by incoming signal valve 2, and the port of export connects the water out adapter 6 that is connected with the system side pipe network by foam proportioner 4 after export signal valve 5.The entrance point of foam solution control valve 7 connects the pressure foam solution through filter 10, and the port of export links to each other with foam proportioner 4 through check valve 12.Water supply connector 1 links to each other with the control chamber of main valve 3 and the control chamber of foam solution control valve 7 respectively by the main valve control piper from the side.Be serially connected with the anti-valve 3d that resets on the main valve control piper, and be provided with bypass emergency start valve 3e and bypass magnetic valve 3c.In addition, the side of foam proportioner 4 is connected with test draining bypass among Fig. 1, is serially connected with test draining valve 9 in the test draining bypass.3a is a pressure switch among Fig. 1, and 3b is the water conservancy alarm bell, the 8th, and terminal box.
This valve group is as a critical piece of foam deluge system, form complete fire extinguishing system with fire water supply equipment, foam solution supply arrangement, pipe network and end sprayer, in the building, structures and all kinds of traffic tunnel that have flammable liquid to exist, as: places such as dangerous goods store, garage, hangar, chemical plant, boiler room, cross-river tunnel, seabed tunnel.Be specially adapted to the protection and the fire extinguishing in tunnel.In addition, to the category-A fire of common material, and the fire of material such as rubber, plastics, synthetic fibers also has and well puts out effect.The configurable a plurality of universal drench valve control valve groups of one cover foam deluge system realize the fire-fighting protection of several corresponding protection zones.
Under set condition, the drench with rain main valve 3 and the foam solution control valve 7 of control valve group of universal foam is normally closed, and signal valve 2 and signal valve 5 all are in normally open, are full of press water and pressure foam solution before main valve import department and the foam solution control valve 7.When the breaking out of fire of protection zone; fire detector element feeds back to control centre with fire signal; control centre is after judging; send the fire extinguishing instruction; open the bypass solenoid valve 3c on the main valve control piper, make the pressure release of main valve barrier film control chamber, thereby open main valve; simultaneously the control chamber of foam solution control valve 7 is also because of the action pressure release of bypass solenoid valve 3c, so foam solution control valve 7 also can be opened simultaneously.The foam solution that has pressure enters foam proportioner 4 behind the main valve 3 by the foam solution control valve, forms foam mixing liquid with press water ratio in accordance with regulations by main valve, enters system pipe network, by the end sprayer ejecting extinguishing.End sprayer can be foam spray shower nozzle (forming the foam spray fire extinguishing system this moment) or foam spray shower nozzle (forming the foam spray fire extinguishing system this moment).After the main valve events, the warning water system 3b and the pressure switch 3a that are positioned at its warning pipeline all can move.Warning water system 3b sends acoustic alarm signal, and prompting Field Force system moves, and pressure switch 3a then feeds back to the pump switch board with the enabling signal of system, starts fire pump and foam pump, for system provides pressure flow and foam dope endlessly.
As after finding fire, it is malfunctioning warning system to occur, when failing to start fire extinguishing system automatically, can carry out emergency start at the scene by opening the bypass emergency start valve 3e on main valve 3 control pipers.Can make the control chamber pressure release of main valve 3 and foam solution control valve 7 equally, start foam drench valve group.
The anti-valve 3d that resets on the main valve control piper is after main valve 3 is opened, transfer closed condition to by original opening, the pressure feed of the barrier film control chamber of cut-out main valve 3 and the control chamber of foam solution control valve 7, can make whole foam drench valve group be locked in opening, cause foam drench valve group to be closed from horizontal reset to avoid accident power-off owing to magnetic valve 3c to reset.
When need drench with rain the control valve group when overhauling to universal foam, close incoming signal valve 2 and outlet signal valve 5, signal valve feeds back to control centre with shutdown signal, and prompt system is in inspecting state.When foam rainforest control valve group is debugged, but shutdown signal valve 5 is opened testing valve 10, can avoid bubble jet to be put into the protection zone.
Facts have proved that present embodiment has following remarkable advantage:
1. will drench with rain alarm valve, foam proportioner and foam solution control valve combines compactly, forms the unit of a standard modular, as the region control block of foam deluge system;
2. the control interlock of the startup of alarm valve and foam solution control valve that will drench with rain, thus realize starting water and foam control valve simultaneously by an electric enabling signal, increase the reliability of system, reduce the system electric control requirement.
