1. Pib los ntawm kev ntxuav cov xov uas siv cov hlau txhuam los yog cov ntaub pua plag kom tshem tawm cov av, cov khib nyiab, lossis cov ntaub nplaum qub.
2. Pib wrapping daim kab xev nyob ib ncig ntawm cov txiv neej threads nyob rau hauv lub opposite kev taw qhia ntawm lub nruj kev txiav txim (clockwise rau txoj cai-tes threads).
3. Tuav qhov kawg ntawm daim kab xev tiv thaiv cov xov thiab pib qhwv hauv ib qho kev sib tw, ua kom nws nruj tab sis tsis nruj heev.
4. qhwv daim kab xev tsawg kawg peb zaug nyob ib ncig ntawm tus txiv neej threads, npog txhua qhov chaw sib npaug.
5. Tshem tawm daim kab xev los ntawm yob thiab nias qhov kawg tiv thaiv cov xov kom ruaj ntseg rau hauv qhov chaw.
6. Sib dhos cov xov txuas los ntawm kev sib txuas ntawm cov hlua khi rau ntawm cov yeeb nkab taped kom nruj, kom tsis txhob overtighten thiab puas lub foob.
Kev ua tau zoo ntawm cov yeeb nkab xov kab xev:
Cov yeeb nkab xov kab xev feem ntau ua tau zoo los tiv thaiv cov xau thaum siv kom raug. Nws tsim ib tug txhim khu kev qha foob ntawm cov threaded nto, txo txoj kev pheej hmoo ntawm to heev. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov yeeb nkab xov kab xev tsis yog ib qho kev kho-txhua qhov kev daws teeb meem thiab nws cov txiaj ntsig yog nyob ntawm ntau yam, xws li qhov zoo ntawm daim kab xev, xov zoo, thiab daim ntawv thov kom raug.
Nws yog ib qho tsim nyog hais tias cov yeeb nkab xov kab xev yog qhov zoo tshaj plaws rau kev sib khi dej thiab cua sib txuas thiab tsis pom zoo siv rau qee yam tshuaj lossis roj. Nyob rau hauv cov ntaub ntawv no, tej yam sealants los yog tshwj xeeb threads yuav tsum tau kom muaj ib tug zoo sealant.
Alternatives rau Tube Thread Tape:
Txawm hais tias cov yeeb nkab xov kab xev yog cov tshuaj siv dav, muaj lwm txoj hauv kev los tsim cov ntsaws ruaj ruaj. Qee cov kev xaiv uas muaj xws li:
1. Yeeb Nkab Dope: Cov yeeb nkab dope yog cov khoom siv zoo li cov yeeb nkab uas yog siv rau cov yeeb nkab xov kom ua tiav qhov kev sib txuas ruaj ntseg thiab tsis muaj dej xau. Nws yog tshwj xeeb tshaj yog pab tau nyob rau hauv high-pressure daim ntaub ntawv thiab qhov chaw uas tsis kam mus rau cov tshuaj thiab huab cua kub yuav tsum tau.
2. O-Rings: O-rings yog cov khoom siv sib khi ua los ntawm roj hmab lossis elastomers. Lawv yog siv nyob rau hauv kev sib txuas nrog threaded kev twb kev txuas los muab ib tug txhim khu kev qha foob tiv thaiv to. O-rings feem ntau yog siv hauv cov kav dej xws li cov faucets thiab cov taub hau da dej.
3. Thread Sealants: Thread sealants yog cov kua sib xyaw ua kua uas siv rau cov kev sib txuas ntawm threaded los sau qhov khoob thiab tiv thaiv kom tsis txhob xau. Cov sealants no tuaj nyob rau hauv ntau yam formulations, xws li anaerobic, daim kab xev, thiab muab tshuaj txhuam. Lawv haum rau ntau hom kev siv thiab tuaj yeem muab cov khoom sib khi zoo heev.
Nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev cai tshwj xeeb ntawm kev siv cov kav dej thaum xaiv lwm txoj hauv kev rau cov yeeb nkab xov kab xev. Cov yam ntxwv xws li kub, siab, thiab tshuaj lom neeg sib xyaw yuav tsum raug coj mus rau hauv tus account.
