Taw qhia
Xov kab xev, tseem hu ua tuber' daim kab xev lossis Teflon daim kab xev, yog ib hom kab xev uas tau siv dav hauv cov kav dej thiab lwm yam lag luam. Daim kab xev no, ua los ntawm ib hom polymer hu ua polytetrafluoroethylene (PTFE), yog siv los kaw cov pob qij txha thiab tiv thaiv kom tsis txhob xau. Nyob rau hauv tsab xov xwm no, peb yuav delve tob rau hauv dab tsi xov daim kab xev siv rau, nws txawv hom, yuav ua li cas siv nws, thiab ib co lus qhia los pab koj kom tau ntau tshaj ntawm nws.
Dab tsi yog xov kab xev siv rau?
Xov kab xev feem ntau yog siv rau kev sib khi threaded pob qij txha hauv cov kav dej, HVAC (cua sov, qhov cua, thiab cua txias), thiab lwm yam lag luam. Thaum ob lub kav dej los yog fittings raug ntsia ua ke, feem ntau muaj qhov sib txawv me me ntawm lawv. Qhov sib txawv no tuaj yeem ua rau xau yog tias nws tsis raug kaw kom zoo, ua rau muaj teeb meem loj.
Xov kab xev yog siv rau cov txiv neej threads ntawm ib tug haum los yog yeeb nkab ua ntej nws yog screwed rau hauv cov poj niam threads ntawm lwm yam. Thaum ob tug tau nruj, daim kab xev compresses nruab nrab ntawm cov xov los ua ib qho kev ua kom huv si wayertight foob, tiv thaiv kom tsis txhob muaj tshwm sim los ntawm kev tshwm sim.

- Oxygen-Approved Thread Tape: Hom kab xev no tshwj xeeb tsim los siv rau hauv cov pa oxygen lossis lwm yam roj. Nws yog tsim los ntawm PTFE, tab sis nws yog tshwj xeeb yog kho los tiv thaiv combustion thiab txo qhov kev pheej hmoo ntawm kev kis kab mob.
- Nickel-Coated Thread Tape: Daim kab xev no muaj txheej txheej ntawm nickel txheej uas muab ntxiv zog thiab tiv thaiv corrosion. Nws yog ib qho kev xaiv zoo rau kev siv nyob rau hauv ib puag ncig corrosive heev, xws li dej ntsev.
Yuav Siv Xov Tooj Li Cas
Kev siv xov kab xev yog qhov yooj yim, tab sis muaj ob peb kauj ruam tseem ceeb uas koj yuav tsum tau ua raws li txhawm rau xyuas kom muaj lub foob zoo.
1. Pib los ntawm kev xaiv hom kab xev rau koj daim ntawv thov. Xav txog cov ntsiab lus ntawm cov yeeb nkab, qhov kub thiab txias ntawm qhov system, thiab lwm yam uas yuav cuam tshuam rau kev ua haujlwm ntawm daim kab xev.
2. Ntxuav cov xov ntawm ob qho tib si txiv neej thiab poj niam cov khoom nrog ib tug hlau txhuam los yog ntawv xuab zeb. Qhov no yuav xyuas kom meej tias daim kab xev ua kom zoo thiab yuav tiv thaiv kom tsis txhob muaj cov khib nyiab cuam tshuam nrog lub foob.
3. Tuav qhov kawg ntawm daim kab xev tiv thaiv cov txiv neej threads thiab qhwv nws ncig ntawm cov xov nyob rau hauv ib tug clockwise kev taw qhia. Nco ntsoov tias daim kab xev overlaps nws tus kheej los ntawm ib nrab ntawm nws qhov dav. Nws yog ib qho tseem ceeb kom tsis txhob qhwv daim kab xev nruj heev.
4. Thaum cov xov tau ntim rau hauv daim kab xev, siv koj cov ntiv tes los nias daim kab xev rau hauv qhov chaw thiab xyuas kom meej tias nws tau ua tiav tag nrho. Txiav ib daim kab xev ntau dhau nrog ib nkawm txiab los yog riam ntse.
5. Screw tus txiv neej tivthaiv rau hauv cov poj niam tivthaiv, xyuas kom meej tias ob leeg nruj nruj. Daim kab xev yuav compress nruab nrab ntawm threads los ua ib tug watertight seal.
Tswv yim rau siv xov kab xev
Nov yog qee cov lus qhia uas tuaj yeem pab koj kom tau txais txiaj ntsig zoo tshaj plaws ntawm cov xov paj:
- Siv daim kab xev kom raug. Daim kab xev me me tuaj yeem ua rau cov xau, thaum daim kab xev ntau dhau tuaj yeem cuam tshuam nrog cov xov thiab tiv thaiv kom raug foob.
- Siv txoj cai tuab ntawm daim kab xev. Thicker daim kab xev yog tsim rau kev thov ntau dua, thaum daim ntaub nyias nyias yog yooj yim rau kev ua hauj lwm nrog thiab ntau nqi-zoo.
- Siv hom kab xev rau koj daim ntawv thov. Xav txog cov ntsiab lus ntawm cov yeeb nkab, qhov kub thiab txias ntawm qhov system, thiab lwm yam uas yuav cuam tshuam rau kev ua haujlwm ntawm daim kab xev.
- Tsis txhob nruj ntawm cov khoom. Qhov no tuaj yeem ua rau daim kab xev deform los yog tsim kua muag, ua rau xau.
- Tshawb xyuas cov dej xau tom qab kev teeb tsa. Txawm tias nrog daim kab xev, cov xau tseem tuaj yeem tshwm sim. Kuaj lub kaw lus rau kev xau ua ntej siv nws.
