Ukuqubuka komlilo bekulokhu kubeka engcupheni enkulu empilweni yomuntu kanye nempahla. Amasu nemishini yokucisha umlilo ibalulekile ekulawuleni nasekucimeni imililo ngokushesha. Ingxenye ebalulekile yanoma yiluphi uhlelo lokucisha umlilo ivalvu yokuqeda umlilo. Lawa mavalvu adlala indima ebalulekile ekulawuleni ukugeleza nokucindezela kwamanzi noma ezinye izinto ezicisha umlilo ezisetshenziselwa ukucisha umlilo. Kulesi sihloko, sizohlola izinhlobo ezahlukene zama-valve okulwa nomlilo kanye nezinhloso zawo.
1. Ivalve yesangos: Lawa ma-valve avame ukusetshenziswa kuma-fire hydrants kanye nezinhlelo zephampu yomlilo. Baziwa ngekhono labo lokulawula ukugeleza komfutho ophezulu, okubenza balungele ukuvala ukunikezwa kwamanzi ngesikhathi sezimo eziphuthumayo. Ama-valve amasango angakwazi ukuphatha umthamo omkhulu wamanzi, okuvumela izicishamlilo ukuba zibhekane nemililo emikhulu ngendlela efanele.
2. Amavalvu Ovemvane: Lawa mavalvu angasindi futhi ahlukahlukene kakhulu. Zivame ukusetshenziswa ezinhlelweni zokucisha umlilo ezidinga ukuvulwa nokuvala ngezikhathi ezithile. Ngenxa yokwakheka kwawo okuhlangene, amavalvu ovemvane kulula ukuwafaka nokusebenza. Banikeza amandla okuvala ngokushesha, ukunciphisa ukulahlekelwa kwamanzi nokunciphisa umonakalo ongase ube khona.
3. Ama-Ball Valves: Ama-valve ebhola asetshenziswa kakhulu ezinhlelweni zokufafaza umlilo kanye nezinhlelo ze-standpipe. Ahlanganisa ibhola elinembobo phakathi, elilawula ukugeleza kwamanzi noma amanye ama-agent. Amavalvu ebhola ahlinzeka ngokulawula okuhle kakhulu kokugeleza futhi eza ngobukhulu obuhlukahlukene nezinto zokwakha, okuvumela ukwenziwa ngokwezifiso okusekelwe ezidingweni ezithile zokulwa nomlilo.
4. Amavalufu Wokuhlola: Amavalvu okuhlola aqinisekisa ukuthi ukugeleza kwamanzi noma izicindezeli zomlilo kuhamba ohlangothini olulodwa kuphela. Bavimbela ukubuyela emuva, ukugcina amanzi njalo ohlelweni lokulwa nomlilo. Lawa ma-valve abalulekile ekuvimbeleni ukungcoliswa kwamanzi kanye nokuqinisekisa ukusebenza kahle komsebenzi wokulwa nomlilo.
5. Amavalvu Okunciphisa Ingcindezi: Njengoba igama liphakamisa, ama-valve okunciphisa ingcindezi asetshenziselwa ukulawula nokugcina ingcindezi oyifunayo ngaphakathi kwesistimu yokucisha umlilo. Baqinisekisa ukuthi izinciphisi zamanzi noma zomlilo zilethwa ngengcindezi efanele ukuze kucishwe umlilo ngempumelelo. Lawa ma-valve adlala indima ebalulekile ekuvimbeleni ukulimala kwemishini yokucisha umlilo ngenxa yengcindezi eyeqile.
Ukuqonda izinhlobo ezahlukene zamavalvu okulwa nomlilo kubalulekile ekuklameni nasekusebenziseni izinhlelo ezisebenzayo zokucisha umlilo. Uhlobo ngalunye lwe-valve lufeza injongo ethile futhi ludlala indima ekuqinisekiseni impumelelo yemisebenzi yokucisha umlilo. Ngokukhetha i-valve efanelekile nokuqonda ukusebenza kwayo, izicishamlilo kanye nabasebenzi bokuphepha komlilo bangaqinisekisa ukusatshalaliswa kwamanzi okuphumelelayo, izikhathi zokuphendula ngokushesha, kanye nokucisha umlilo okuphumelelayo.
