Hauv tsab xov xwm no, peb yuav tham txog vim li cas nws tseem ceeb heev rau kev siv cov tshev valve hauv kev tiv thaiv hluav taws.
Ua ntej, kos li qub ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas kev ncaj ncees ntawm koj cov dej. Hauv cov txheej txheem tiv thaiv hluav taws, kos li qub kom ntseeg tau tias cov dej ntws hauv ib qho kev taw qhia, feem ntau yog los ntawm cov dej tseem ceeb mus rau cov khoom siv tiv thaiv hluav taws. Qhov no ib-txoj kev ntws yog qhov tseem ceeb los xyuas kom meej tias cov dej mus txog nws qhov chaw xav tau sai sai thaum muaj hluav taws kub. Yog tsis muaj daim tshev valve, dej tuaj yeem thim rov qab, ua rau poob ntawm cov dej siab thiab tej zaum yuav ua rau lub cev tiv thaiv hluav taws tsis ua haujlwm.
Lwm qhov laj thawj uas siv cov tshev valve hauv kev tua hluav taws yog tiv thaiv kev sib kis. Cov li qub no pab tswj kev ua kom huv ntawm koj cov dej los ntawm kev tiv thaiv ib qho kev rov qab uas tuaj yeem qhia txog cov khoom txawv teb chaws lossis cov kab mob hauv lub cev. Cov dej paug paug tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov twj tua hluav taws, cov neeg tua hluav taws thiab lwm yam khoom siv tua hluav taws. Los ntawm kev siv cov tshev valve, peb tuaj yeem ua kom ntseeg tau tias cov dej huv huv thiab tsis muaj kab mob.
Tsis tas li ntawd, kos li qub ua rau muaj kev cia siab tag nrho thiab kev ua haujlwm ntawm kev tiv thaiv hluav taws. Lawv pab txo qis kev pheej hmoo ntawm kev puas tsuaj ntawm lub twj tso kua mis thiab tswj cov dej kom tsis tu ncua los ntawm kev tiv thaiv cov dej rov qab. Los ntawm kev tswj xyuas cov dej ntws zoo ib yam, cov khoom siv hluav taws xob txhawb kev ua haujlwm kom zoo ntawm cov tshuab hluav taws xob, hose reels, hydrants thiab lwm yam khoom siv tiv thaiv hluav taws. Qhov no ua kom ntseeg tau tias cov khoom siv no yeej ib txwm npaj txhij los ua tam sim ntawd thaum muaj hluav taws kub, tiv thaiv kev sib tsoo thiab khoom puas tsuaj.
Hauv cov ntsiab lus, kev siv cov tshev valve hauv kev tiv thaiv hluav taws yog qhov tseem ceeb rau ntau yam laj thawj.
