The specific embodiment
Embodiment one:
Referring to Fig. 2 (arrow among the figure is represented the flow direction of press water), automatic water sprinkler systme of the present invention, a fire extinguishing water supply installation (not showing among the figure) is arranged, this water supply installation output is connected with the pipe network main pipeline, series connection water control valve 3 in the described pipe network main pipeline 100, this water control valve water outlet one side connects a plurality of open type sprinkler heads 5 by pipe network pipeline, a cover overflow valve 4 in parallel at least on the pipe network main pipeline between described water control valve and the open type sprinkler head.
Open type sprinkler head described in the present embodiment is the head water shower nozzle, the opening pressure value P of head water shower nozzle
kClosing presure value P greater than overflow valve
g
Under the non-normal working situation (because of pipe network water pressure fluctuation or water control valve operate miss), water control valve in the system of the present invention is unexpected to be opened, having press water in the pipe network main pipeline of water control valve water outlet one side flows into, owing to be improper unlatching, hydraulic pressure is lower in the pipe network main pipeline, and its hydraulic pressure value is lower than the closing presure value P of overflow valve
g, at this moment, all head water shower nozzles still are in closed condition, and the water that enters in the pipe network main pipeline can only be gone out from described overflow valve earial drainage, can not spray from the head water shower nozzle, thus the purpose of realization preventing from mistake in jetting.
Admire down normal nozzleman, the water control valve in the system of the present invention is normally opened, and hydraulic pressure value is greater than the closing presure value P of overflow valve in the pipe network main pipeline of water control valve water outlet one side
g, described overflow valve cuts out; At this moment, hydraulic pressure value is higher than the opening pressure value P of head water shower nozzle in the pipe network main pipeline
k, all head water shower nozzles are opened, and realize normal automatic sprinkling fire-extinguishing.
Referring to Fig. 3 (arrow among the figure is represented the flow direction of press water), overflow valve of the present invention is a kind of pressure-control valve, when the hydraulic pressure of its inlet end does not reach its closing presure value P
gThe time, overflow valve is an opening, press water can be gone out by the water outlet end earial drainage of overflow valve; When the hydraulic pressure of its inlet end meets or exceeds its closing presure value P
gThe time, overflow valve is a closed condition, water can not pass through overflow valve.Described overflow valve is made up of nut 101, sealing plate 102, spring 103, ring-type valve seat 104, valve body 105, valve rod 106, fairlead 107, valve gap 108.The lower port of overflow valve is an inlet end, inserts the pipe network main pipeline by pipeline, and the upper port of overflow valve is a water outlet end, is used for earial drainage.Valve body is cylindrical, valve body middle part screw thread is fixed a ring-type valve seat, valve body top screw thread is fixed a valve gap, in this valve gap fairlead is installed, this fairlead is provided with a plurality of water holes, stem lower portion is installed the sealing plate with ring-type valve seat coupling, valve rod middle part pocketed springs, and valve rod top is installed in the fairlead.The operation principle of overflow valve is: when the hydraulic pressure value of valve inleting water mouth end does not reach its closing presure value P
gThe time, rely on this hydraulic pressure sealing plate upwards can be passed, open valve inleting water mouth end, still, sealing plate can not move to the annular valve seat and put, and press water will be by the ring-type valve seat, and the water hole on the fairlead of flowing through flows out from the overflow valve water outlet end then.When valve inleting water mouth end hydraulic pressure reaches closing presure value P
gThe time, press water is upwards passed sealing plate, moves to the annular valve seat and puts, and with airtight the combining of ring-type valve seat, at this moment, press water can not pass through the ring-type valve seat, and overflow valve cuts out.
Referring to Fig. 4 (arrow among the figure is represented the flow direction of press water), the used head water shower nozzle of present embodiment is with pressure-type control valve and sprinkler head design all-in-one-piece structure.The head water shower nozzle is to be made of spring 201, valve rod 202, nozzle housing 203, swirler assembly 204, owing to be conventional products, is not described in detail.When its import hydraulic pressure did not reach its opening pressure value, shower nozzle was a closed condition, and when its import hydraulic pressure met or exceeded its opening pressure value, shower nozzle was an opening.
Head water shower nozzle of the present invention can also adopt other version except the version that Fig. 4 shows, for example can be to adopt obstruction or blocking cap to get lodged in the spout place or the nozzle place of each sprinkler head, pressure reaches and stops up behind the certain value or blocking cap comes off, obstruction or blocking cap use as a kind of control valve (or open valve), reach the purpose of level pressure water spray; Also can be to set up a pressure-control valve on common open type sprinkler head, after the import water pressure of each sprinkler head reached the pressure-control valve value, pressure-control valve be opened, and realized the purpose of level pressure water spray
Embodiment two:
Referring to Fig. 5, automatic water sprinkler systme of the present invention, a fire extinguishing water supply installation (not showing among the figure) is arranged, this fire extinguishing water supply installation output is connected with the pipe network main pipeline, series connection water control valve 6 in the described pipe network main pipeline 100, this water control valve water outlet one side connects a plurality of open type sprinkler heads 9 by pipe network pipeline, and the control valve 8 of connecting on the pipe network main pipeline between water control valve and the open type sprinkler head, described overflow valve 7 are connected in parallel on the pipe network main pipeline between described water control valve and the control valve.
Overflow valve in the present embodiment is identical with overflow valve among the embodiment one, and referring to Fig. 6, the control valve of present embodiment is a pressure-control valve, and control valve is made of spring 301, valve rod 302, fairlead 303, valve body 304, valve gap 305, valve plate 306.The lower port of control valve is an inlet end, and its upper port is a water outlet end.It is cylindric that valve body is, and valve body top screw thread is fixed a valve gap, and fairlead is installed in the valve gap, this fairlead is provided with a plurality of water holes, and valve rod top is installed in the fairlead, and stem lower portion is installed valve plate, valve rod middle part pocketed springs, this valve plate combine with the valve body lower end mouth and constitute a valve.
Control valve in the present embodiment is the break-make that the size of the pressure of utilization fire extinguishing water is controlled the pipe network main pipeline.When its import hydraulic pressure does not reach its opening pressure value P
kThe time, control valve is a closed condition, water can not flow out by control valve; When control valve import hydraulic pressure meets or exceeds its opening pressure value P
kThe time, control valve is an opening, water can flow out by valve body.Its course of work is that anhydrous when the control valve inlet end, when perhaps hydraulic pressure was not enough, under the elastic force effect of spring, valve plate was closed inlet end, can prevent that effectively sealing passes through from control valve.The fire extinguishing water supply installation formally starts, and control valve inlet end pressure raises, and after the pressure of fire extinguishing water is enough to overcome the elastic force of spring, valve plate will move up, and control valve is opened, and fire extinguishing water flows out by valve body.
In the present embodiment, the opening pressure value P of described control valve
kClosing presure value P greater than overflow valve
