See Fig. 7 and Fig. 9 again, operating-controlling mechanism 90 comprises handle 91, minor axis 92, pin 93, first rotating disk 94 and the second rotating disk 96.Minor axis 92 is arranged on the bottom of handle 91, and the two ends, left and right of minor axis 92 are located in the axis hole of axis hole neutralization the 3rd bearing block 85 of the second bearing block 84 of frame 8 respectively.Pin 93 be located at the middle part of handle 91 and about it two terminations protruding respectively.First rotating disk 94 arranges the circular arc groove 95 that fan-shaped angle is 90 ° the position of 9 o'clock to 12 o'clock.Second rotating disk 96 arranges the circular arc groove 97 that fan-shaped angle is 90 ° the position of 12 o'clock to 3 o'clock.The width of these two circular arc grooves 95,97 is identical and radius of curvature is identical.First rotating disk 94 is co-axially mounted on cock axle 5100 right end of the first triple valve 50 also near the second bearing block 84.Second rotating disk 96 is co-axially mounted on the cock axle 7100 left end head of the second triple valve 70 also near the 3rd bearing block 85.On handle 91, the left end head of pin 93 is inserted in the circular arc groove 95 of the first rotating disk 94, and the right end of this pin 93 is inserted in the circular arc groove 97 of the second rotating disk 96.
When handle 91 is erect, be in the first state W1, please refer to Figure 10: the pin 93 on handle 91 is in the position of 12, in the first triple valve 500 wind spring reseting torque effect under its cock axle 5100 drive the front end of the first rotating disk 94 circular arc groove 95 to withstand the left end head of pin 93, in the second triple valve 700 wind spring reseting torque effect under the rear end of circular arc groove 97 of the second rotating disk 96 withstand the right end of pin 93.Now, the first triple valve 50 cock axle 5100 is in the first state, and the passage 5400 of cock 5300 makes public port 5800 be communicated with the first port 5210; Namely the entrance 31 of electrodynamic pump 3 is communicated with the efferent duct 41 of helitank 4.The cock axle 7100 of the second triple valve 700 is in the first state, and the passage 7400 of cock 7300 makes public port 7800 be communicated with the first port 7210; Namely the outlet 32 of electrodynamic pump 3 is communicated with woven hose 2.The present embodiment is in normal operation state.Now, once start electrodynamic pump 3, the one-component extinguishing chemical in helitank 4 outwards will be sprayed from shower nozzle 1 by efferent duct 41, electrodynamic pump 3, woven hose 2, can reach the effectiveness of fire extinguishing.Close electrodynamic pump 3, the one-component extinguishing chemical in helitank 4 stops outwards spraying from shower nozzle 1.
As the second state W2 that handle 91 stretches out from the first state W1 counter-clockwise swing 90 ° erect with being up to the standard backward, please refer to the Figure 11: the first rotating disk 94 and keep motionless, the left end head of pin 93 slides backward 90 ° clockwise along the first rotating disk 94 circular arc groove 95; And the right end of pin 93 pushes the rear end counter-clockwise swing 90 ° of the circular arc groove 97 of the second rotating disk 96, the pin 93 on handle 91 arrives the position of 9.Namely the second rotating disk 96 is with cock axle 7100 counter-clockwise swing 90 ° of the second triple valve 700, and the wind spring be located in the second triple valve 700 is rolled tightly.Now, the cock axle 5100 of the first triple valve 500 is still in the first state, and public port 5800 is communicated with the first port 5210; The entrance 31 of electrodynamic pump 3 is communicated with the efferent duct 41 of helitank 4.The cock axle 7100 of the second triple valve 700 turns over 90 ° counterclockwise and is in the second state, and public port 7800 is communicated with the second port 7220; The outlet 32 of electrodynamic pump 3 is communicated with the input pipe 42 of helitank 4.The present embodiment is in extinguishing chemical conveying loop detected state.Now, once start electrodynamic pump 3, the input pipe 42 by efferent duct 41, electrodynamic pump 3, helitank 4 is returned helitank 4 by the one-component extinguishing chemical in helitank 4.If arrange transparent observation window on the input pipe 42 of helitank 4, observe the flowing of one-component extinguishing chemical, just illustrate from helitank 4, the extinguishing chemical conveying loop through electrodynamic pump 3 is unimpeded.In the process that extinguishing chemical conveying loop detects, one-component extinguishing chemical is got back in helitank 4 through extinguishing chemical conveying loop, can not consume.
Make handle 91 from the second state W2 counter-clockwise swing 90 °, get back to pin 93 at the first state W1 of 12; On handle 91, the termination, two, left and right of pin 93 slide rearwardly to the rear end of these two circular arc grooves 95,97 respectively along the circular arc groove 95 of the first rotating disk 94 and the circular arc groove 97 of the second rotating disk 96.The restoring force of the wind spring in the second triple valve 700 makes the cock axle 7100 of the second triple valve 700 continue to rotate clockwise 90 ° with the second rotating disk 96, because the right end of pin 93 is motionless, the right end of pin 93 is withstood in the rear end of the circular arc groove 97 of final second rotating disk 96.The present embodiment gets back to conventional sense again.
When handle 91 is from the first state W1 clockwise oscillation 90 ° of third state W3 stretched out forward with being up to the standard erect, please refer to the Figure 12: the second rotating disk 96 and keep motionless, the right end of pin 93 along circular arc groove 97 forward slip of the second rotating disk 96, until reach the front end of this circular arc groove 97.The left end head of pin 93 pushes the right-hand member clockwise oscillation 90 ° of the first rotating disk 94 circular arc groove 95, and the pin 93 on handle 91 is in the position of 3.Thus the wind spring in the first triple valve 500 is rolled tightly.Now, the cock axle 5100 of the first triple valve 500 turns over 90 ° clockwise and is in the second state, and public port 5800 is communicated with the second port 5220.The entrance 3 of electrodynamic pump 3 is communicated with the outlet pipe 61 of Experimental Water Tank 6.The cock axle 7100 of the second triple valve 700 is in the first state, and public port 7800 is communicated with the first port 7210.The outlet 32 of electrodynamic pump 3 is communicated with woven hose 2, and the present embodiment is in spray loop detected state.Now, once start electrodynamic pump 3, the clear water in Experimental Water Tank 6 outwards will be sprayed from spray head 1 by efferent duct 61, electrodynamic pump 3, woven hose 2.And one-component extinguishing chemical can not be consumed.
Make handle 91 from third state W3 counter-clockwise swing 90 °, get back to pin 93 at the first state W1 of 12; The termination, two, left and right of the pin 93 on handle 91 slide rearwardly to the rear end of these two circular arc grooves 95,97 respectively along the circular arc groove 95 of the first rotating disk 94 and the circular arc groove 97 of the second rotating disk 96.The restoring force of the wind spring of the first triple valve 500 inside makes the cock axle 5100 of the first triple valve 500 continue to rotate counterclockwise 90 ° with the first rotating disk 94, because the left end head of pin 93 is motionless, the left end head of pin 93 is withstood in the front end of the circular arc groove 95 of final first rotating disk 94.The present embodiment gets back to conventional sense again.
Because user can only operate the first triple valve 500 and the second triple valve 700 by the handle 91 of operating-controlling mechanism 90.There will not be the problem of aberrant state while of the first triple valve 500 and the second triple valve 700, so the maloperation of operator can be prevented, cause the water in Experimental Water Tank 6 to enter helitank 4.
