Tsis siv neeg kaw
Lub valve feem ntau yog ntsia rau hauv cov yeeb nkab ntawm UST. Thaum lub tank nce mus txog qib uas tau txiav txim siab ua ntej (feem ntau nyob ib puag ncig 90-95%), lub valve cia li kaw, nres qhov ntws ntawm cov roj los yog kua rau hauv lub tank kom tsis txhob ntws tawm.
Tiv Thaiv Kev Txhaum Cai thiab Kev Tiv Thaiv Ib puag ncig

Txhim khu kev nyab xeeb
Overfilling tuaj yeem tsim teeb meem kev nyab xeeb, suav nrog kev pheej hmoo ntawm hluav taws, yog tias muaj cov kua hluav taws xob cuam tshuam. Lub valve pab tswj kev nyab xeeb los ntawm kev ua kom tsis muaj kua ntau dhau ntawm lub tank.
Cov txheej txheem no yog ib feem tseem ceeb ntawm UST kev nyab xeeb thiab kev ua raws li ib puag ncig, txo qhov kev pheej hmoo ntawm cov khoom kim heev thiab kev puas tsuaj ib puag ncig.
