Ua ntej, cov tub ntxhais valve yuav tsum yog kev sib xyaw ua ke ntawm siab - ntom ceramic thiab tooj liab valve lub cev. Tsis txhob cia li saib cov lus thov tshaj tawm; tshawb xyuas cov ntawv ceeb toom rau qhov qhib thiab kaw lub neej ntev thiab ua haujlwm rau thermal shock. Cov ntsiab lus tseem ceeb no txiav txim siab seb koj puas yuav sawv los ntawm kev xau thaum nruab nrab hmo ntuj rau tsib xyoos tom ntej.
Qhov thib ob, tag nrho cov khoom zais zais yuav tsum txhawb kev saib xyuas yam tsis muaj kev rhuav tshem cov phab ntsa. Ua tib zoo saib xyuas seb qhov sib tov puas tuaj yeem rub tawm tag nrho, seb lub hau npog puas muaj qhov sib nqus nrawm-tso tawm mechanism, thiab seb lub qhov hluav taws xob puas muaj kev tiv thaiv - tig qhov chaw zawj. Cov ntsiab lus no txiav txim siab seb tus nqi kho puas yog ob peb puas lossis ntau txhiab daus las.
Thib peb, kev paub txog dej ntws yuav tsum tiv taus kev sim txhua hnub. Piv txwv li, lub taub hau da dej puas muaj tus kheej - ntxuav silicone nozzle? Cov da dej saum taub hau puas muaj cua txhaj tshuaj? Puas yog lub tes da dej txhawb nqa ntau-lub kaum sab xis? Txawm hais tias qhov zoo nkauj zoo nkauj npaum li cas, yog tias cov dej ntws hnyav, lub dav hlau dej tawg, lossis qhov hloov pauv yog clunky, nws yog txhua yam rau kev ua yeeb yam.
