Preferably, piston column is pressed in magnetic ring component through fill-in pad and forms spool in the valve core housing.
Preferably, the center hole in the valve gap is equipped with the spool overcoat, and spool is inserted in the spool overcoat, and can in the spool overcoat, move up and down.
Preferably, cover and magnet ring cover in the outside of spool overcoat is with; Interior cover is pressed in magnetic ring component in the magnet ring cover through screw thread, and the magnet ring cover can slide up and down outside the spool overcoat.
Preferably, the middle and upper part of interior cover is equipped with memory alloy spring, and the top of memory alloy spring withstands on the internal upper part of valve bonnet.
Preferably, the outer top of spool overcoat is equipped with depression bar, is with stage clip on the depression bar, and the circular hole at cover top was connected with the adjusting nut of valve bonnet in depression bar passed.The circular hole on the valve bonnet is passed on interior cover top, and the outside of interior cover is with the temperature memory alloy.
Preferably, magnetic ring component, magnetic column assembly are formed by connecting the magnet same polarity more than two, separate with the magnetic gap sheet between the magnet.
The beneficial effect of the utility model is: when outer power has been realized the automatic on-off of spraying system of fire fighting; The detachable shower valve opening/closing mechanism of changing under the user mode; The automatic fire control shower valve has the enforced opening function, the user mode of convenient inspection shower valve.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Accompanying drawing 2 is valve bonnet external views of automatic fire control shower valve;
Among the figure, 1 valve body, 2 piston packings, 3 valve gaps, 4 magnetic ring component, 5 magnet ring covers, 6 memory alloy springs; 7 valve pockets, 8 adjusting nuts, 9 interior covers, 10 magnetic column assemblies, 11 spool overcoats, 12 valve core housings; 13 piston columns, 14 tapped holes, 15 flutings, depression bar 16, stage clip 17, Returnning spring 18; The fire water flow path direction is seen arrow among the figure.
Embodiment
Accompanying drawing 1 is the principle assumption diagram of present embodiment.
A kind of automatic fire control shower valve with enforced opening and detachable dual functions comprises valve body 1, valve gap 3, valve bonnet 7 and is arranged on the shower valve opening/closing mechanism in the described valve bonnet 7 that valve gap 3 is fixedly mounted on the valve body 1; The shower valve opening/closing mechanism is dismountable to be arranged on the valve gap 3; The shower valve opening/closing mechanism comprises magnetic ring component 4, magnet ring cover 5, memory alloy spring 6, Returnning spring 18, magnetic column assembly 10 and piston column 13, it is characterized in that, on the said valve bonnet 7 opening is set; The bottom fluting 15 of said opening; Magnet ring cover 5 exposes on valve bonnet 7 parts tapped hole 14 is set, and screw screws in the said tapped hole, last poppet-valve cover 7; The fluting 15 of valve bonnet 7 is stuck on the screw, and this moment, the fire-fighting spraying valve was forced unlatching.Said piston column 13 is pressed in magnetic column assembly 10 through fill-in pad forms spool in the valve core housing 12.Center hole in the described valve gap is equipped with spool overcoat 11, and spool is inserted in the spool overcoat 11, and can in spool overcoat 11, move up and down.Cover 9 and magnet ring cover 5 in the outside of said spool overcoat 11 is with; Interior cover 9 is pressed in magnetic ring component 10 in the magnet ring cover 5 through screw thread, and magnet ring cover 5 can slide up and down outside spool overcoat 11.The middle and upper part of cover 9 is equipped with memory alloy spring in said, and the top of memory alloy spring withstands on the internal upper part of valve bonnet 7; The outer top of described spool overcoat 11 is equipped with depression bar, is with stage clip on the depression bar, and the circular hole at cover top was connected with adjusting nut 80 on the valve bonnet 7 in depression bar passed.The circular hole on the valve bonnet 7 is passed on interior cover 9 tops, and the outside of interior cover (9) is with the temperature memory alloy.Magnetic ring component 4, magnetic column assembly 10 are formed by connecting the magnet same polarity more than two, separate with the magnetic gap sheet between the magnet.
The structural principle of the utility model is like this work: when not having the condition of a fire to take place at ordinary times at the scene, promptly ambient temperature just often because memory alloy spring 6 is in relaxation state.Memory is closed 6 and is detected ambient temperature and raise suddenly in valve, and when surpassing memory alloy 6 deformation setting values, memory alloy 6 expansion deformation; The mechanical thrust that produces promotes valve pocket 7, and valve pocket 7 moves up, the pulling depression bar; Cover 9 moved up in depression bar drove, and interior cover 9 drives magnetic ring component 4 and moves up, magnetic ring component 4 through the magnetic column assembly 10 in the magnetic strap movable valve plug overcoat 11, promptly drive spool and move up; When spool moves up; Piston column 13 in the spool is moved upward, force seal ring 2 to leave the relief hole on the piston diaphragm, the hydraulic pressure of piston diaphragm top is released; The hydraulic pressure of water intake backs down the piston diaphragm, be valve open in the valve body 1, and the fire-fighting medium is through water outlet, spray through spraying head again.
When the site environment temperature drops to the deformation temperature value of memory alloy 6 when following gradually, memory alloy 6 shrinks rapidly and returns to original remember condition, because stage clip 17 is in confined state; Cover 9, reset spring postpone to discharge after a period of time in forcing, and Returnning spring 18 is under the promotion of the elastic restoring force that discharges, and the magnetic ring component 4 in forcing in the cover 9 moves down; Through the magnetic column assembly in the magnetic strap movable valve plug overcoat 11, promptly drive spool and move down, when spool moved down, the piston column 13 in the spool moved downward; Force the relief hole on the seal ring 2 shutoff upper piston diaphragms; Under the effect of import hydraulic pressure, the piston diaphragm blocks water outlet in the valve, valve closing rapidly; Because the retarding action of stage clip 17; The defective that valve is closed immediately when having avoided memory alloy to shrink has postponed spray time, has improved the spray effect.The degrees of expansion that can regulate memory alloy through the nut of regulating on the depression bar, thus set the unlatching temperature of valve.
When needs enforced opening automatic fire control shower valve, last poppet-valve cover 7 is stuck in the fluting of valve bonnet 7 on the screw, and this moment, the fire-fighting spraying valve was forced unlatching.
Above embodiment's purpose is to explain the utility model, and the protection domain of unrestricted the utility model, all application that come by the utility model simple change all drop in the protection domain of the utility model.
