Embodiment：Water inlet pipe 1, foam to be provided with control cabinet former as shown in Figure 1, the foam-water in the present embodiment is sprayed
This three main conduit lines of liquid pipe 2, foam mixing liquid outlet pipe 3, wherein water inlet pipe 1 and foam dope pipe 2 respectively with foams mix
Liquid outlet pipe 3 is connected, and the connectivity part of three is provided with foam proportioner 6, and the water and foam that water inlet pipe 1 is supplied are former
The foam dope that liquid pipe 2 is supplied mixes at foam proportioner 6 then to be supplied from the outlet of foam mixing liquid outlet pipe 3
Go out, so as to complete the output of foam-water spraying.
As shown in Figure 1, deluge valve 5 is provided with water inlet pipe 1, by controlling the keying of deluge valve 5 to can control water inlet pipe 1
Working status, that is, enable or cut off intake tunnel.Deluge valve 5 has ante-chamber 14 and back cavity 15, in usually servo condition, rain
Leaching valve 5 is closed, and pressurising power water in the ante-chamber 14 of deluge valve 5, back cavity 15 are blank state at this time.Deluge valve 5 is easy
Leakage failure occurs is its internal diaphragm damage, so as to cause leak, i.e., the pressure water in ante-chamber 14 enters back cavity 15
Among.In order to detect the generation of this water leakage fault, immersion type is installed at the immersion type sensor installation position 16 in back cavity 15
Sensor, the immersion type sensor are connected with the leakage alarm 13 as warning device, and leakage alarm 13 is fixedly mounted
Outside the valve body of deluge valve 5.When pressure water enters back cavity 15, based on liquid conduction principle, immersion type sensor is detectable
To pressure water entrance and be converted into dry contact output signal send to leakage alarm 13, so as to fulfill the alarm of leak.
