Extended coverage sprinkler head hais txog lub taub hau sprinkler nrog ib qho chaw tiv thaiv tshwj xeeb loj dua li lub taub hau sprinkler, hu ua EC sprinkler taub hau (cov ntawv luv rau kev txuas ntxiv). Nws muaj cov qauv zoo ib yam li lub taub hau lub taub hau, thiab qhov sib txawv tseem ceeb yog nyob rau hauv cov duab ntawm cov plhaw phaj EC nozzles feem ntau yog siv nyob rau hauv lub teeb-kev pheej hmoo thiab nruab nrab-kev pheej hmoo qhov chaw, thiab lawv qhov siab tshaj plaws kev pab them nqi yog hais txog 5m × 7m. Qhov chaw tiv thaiv ntawm lub nozzle yog 37.2m2, thaum lub siab tshaj plaws tiv thaiv cheeb tsam ntawm tus qauv nozzle tsuas yog 20m2. Nws tuaj yeem pom tau tias qhov kev xaiv raug thiab siv EC Nozzles tuaj yeem txo cov nqi hluav taws xob zoo.

3. Cov chaw uas muaj ib qho ntawm cov kev cai hauv qab no yuav tsum tau txais cov txheej txheem ua ntej:
1. Thaum lub kaw lus nyob rau hauv quasi-ua hauj lwm lub xeev, nws yog nruj me ntsis txwv tsis pub kom xau dej los ntawm lub raj xa dej;
2. Nws yog nruj me ntsis txwv tsis pub tshuaj tsuag lub kaw lus yuam kev;
3. Hloov lub tshuab ziab khaub ncaws.
4. Nyob rau hauv qhov chaw uas cov tshuaj tsuag dej yuav tsum tau nres nyob rau hauv lub sij hawm tom qab tua hluav taws, ib tug pre-action system nrog rov qhib thiab kaw yuav tsum tau saws.
5. Lub tshuab hluav taws xob yuav tsum tau siv rau hauv qhov chaw uas muaj ib qho ntawm cov xwm txheej hauv qab no: 1.
