The specific embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is explained further details:
Embodiment 1:
As shown in Figure 1, the inlet of quick-action control valve 1-2 links to each other with the high pressure fire fighting water source.The quick-action control valve 1-2 port of export and normally open valve 1-3, pressure hydrodynamic(al) valve 1-5, blender 1-6, MJPZ stoste 1-4 and foam nozzle 1-7 form fire extinguishing system.The control mouth of quick-action control valve 1-2 and hand control valve 1-9 form on-site manual console switch system.Quick-action control valve 1-2 control mouth is formed automatically or the operated from a distance switching system with magnetic valve 1-8.
During normal armed state, quick-action control valve 1-2 is in closed condition.When fire alarm took place, as shown in Figure 2, quick-action control valve 1-2 opens had 3 kinds of modes: (1) on-the-spot emergency opening hand control valve 1-9, and quick-action control valve 1-2 control mouth is opened water flowing; (2) on-the-spot high temperature of fire or dense smoke make detector closed, magnetic valve 1-8 connections of switch on, and quick-action control valve 1-2 controls and mouthful opens water flowing; (3) the long distance control system operation is connected magnetic valve 1-8 energising, and quick-action control valve 1-2 control mouth is opened water flowing.After quick-action control valve 1-2 opens; When the fire-fighting water under high pressure flows to blender 1-6 through normally open valve 1-3; Part High-Pressure Water makes pressure hydrodynamic(al) valve 1-5 be in opening to pressure hydrodynamic(al) valve 1-5, and MJPZ liquid is by sucking-off; Flow to blender 1-6, mix the back with fire-fighting pressure water through foam nozzle 1-7 ejection fire extinguishing.
After fire alarm is removed, to close hand control valve 1-9, or make magnetic valve 1-8 outage, quick-action control valve 1-2 control mouth closes up, thereby quick-action control valve 1-2 is closed, and fire-fighting system is got back to normal armed state again.
The opening time of the special-purpose quick-action control valve of the utility model 1-2 is very short, does not almost have time-delay, has reached the function of quick startup aqueous film-forming foam extinguishing agent fire fighting; Adopt special pressure hydrodynamic(al) valve 1-5, hydraulic pressure capable of using is launched MJPZ stoste synchronously automatically, has improved reliability, has reduced the operating time.Simultaneously can pass through detector or remote monitoring, reach the requirement of automatic fire control fire extinguishing and Long-distance Control fire-fighting fire extinguishing.Adopt the multiple spot control operation, reached the purpose of being put out a fire, effectively stoped the development of the intensity of a fire in the starting stage.
Below each description of drawings the operation principle of quick-action control valve 1-2 and pressure hydrodynamic(al) valve 1-5:
Fig. 3 is the structure principle chart of quick-action control valve (1-2), and it is mainly by the first valve body 3-1, and the first spool 3-2 and first compresses compositions such as spring 3-3.When the control mouth closes up; The pressure that gets into the fire water of quick-action control valve 1-2 import passes through the upper end of the damping hole effect first spool 3-2 in the effect first spool 3-2 lower end; Because the first spool 3-2 upper portion pressurized area is greater than the compression area of bottom, the first spool 3-2 receives downward water pressure, under the elastic force of the first compression spring 3-3 acts on simultaneously; The first spool 3-2 and the first valve body 3-1 sealing surface are combined closely, and quick-action control valve 1-2 closes.
When opening the control mouth, this moment, the water pressure on the first spool 3-2 top was released, and the first spool 3-2 is under the effect of bottom upward hydraulic pressure; Overcome the downward pressure of the first compression spring 3-3; Upwards opened rapidly, quick-action control valve 1-2 opens, and fire water brake control valve 1-2 outlet is rapidly discharged.
Fig. 4 is the structure principle chart of pressure hydrodynamic(al) valve, and its main body is by the second valve body 4-1, the second spool 4-2, the second compression spring 4-3, plain cushion 4-4, cylinder body 4-5, piston 4-6, nut 4-7, compositions such as end cap 4-8.When the control water entrance did not have the press water entering, under the second compression spring 4-3 effect, the second spool 4-2 and the second valve body 4-1 were close to; Pressure hydrodynamic(al) valve 1-5 closes, and after press water got into cylinder body 4-5 bottom from the control water entrance, the piston 4-6 and the second spool 4-2 were under press water makes progress the effect of active force; Overcome the active force of the second compression spring 4-3; Move up, pressure hydrodynamic(al) valve 1-5 opens, and foam dope exports by sucking-off through pressure hydrodynamic(al) valve 1-5.1-2 closes when the quick-action control valve, and when press water was disconnected, under the effect of the second compression spring 4-3, piston 4-6 and the second spool 4-2 etc. moved down.Pressure hydrodynamic(al) valve 1-5 is returned to closed condition.
