Kev teeb tsa kev sib txuas lus huv hauv chav tsev lossis tsev tsev inevitably entails kev yuav khoom ntawm cov kav dej tshiab. Yog hais tias tus tswv ntawm qhov chaw nyob yuav tso siab rau kev ua haujlwm rau ntiav cov kws tshaj lij, nws yuav tsis tau nkag siab txog qhov tsis sib xws thiab cov yam ntxwv. Hauv qhov no, kev yuav khoom ntawm cov khoom yuav raug tswj los ntawm cov kws tshaj lij. Txawm li cas los xij, txhawm rau txhim kho nrog koj tus kheej txhais tes lossis tswj kev ua haujlwm ntawm cov kws ua haujlwm koom nrog, koj yuav tsum ua tib zoo kawm txog cov kev xaiv ua tau. Muaj ntau hom khoom, txhua tus muaj lub hom phiaj sib txawv.
cov kav dej yog dab tsi?
Nov yog ib qho ntawm cov kav dej loj. Cov kav dej thiab cov kav dej phwj yog tsim los ntawm cov khoom sib txawv. Muaj ntau hom ntawm lawv:
- steel;
- cam khwb cia hlau;
- tooj;
- metal-yas;
- YPVC;
- los ntawm lwm cov polymers.
Khoom siv los ntawmuas cov yeeb nkab yog tsim los txiav txim qhov chaw ntawm kev siv, txij li cov khoom muaj cov khoom tsim nyog, cov yam ntxwv, qhov zoo thiab qhov tsis zoo.
Cov kav dej hlau yog suav tias yog ib qho ntawm cov neeg ntseeg siab tshaj plaws thiab pheej yig. Cov qauv hlau muaj qhov tsim nyog lub zog, ruaj khov tiv taus siab thiab kub surges. Nws yog ib qho yooj yim mus nrhiav tau qhov tsim nyog fittings, kev sib txuas thiab lwm yam ntxiv rau cov ntaub ntawv zoo li no. Yog tias cov kav dej steel raug teeb tsa kom raug, ces kev sib txuas lus yuav kav ntev txog 50 xyoo. Feem ntau, steel yog siv nyob rau hauv lub installation ntawm risers thiab rhuab phuam rails. Ntxiv nrog rau qhov zoo tsis txaus ntseeg, steel muaj ntau qhov tsis zoo:
- corrosion tsim;
- nplai tso rau ntawm phab ntsa sab hauv;
- condensation sab nraum;
- kim thiab nyuaj installation.
Cov kav hlau cam tsis raug xeb, tiv taus qhov kub thiab txias hloov, tsis txhob cia cov nplais rau hauv daim ntawv thiab muaj zog heev. Lub sijhawm ua haujlwm ntawm cov dej cam khwb cia hlau yog mus txog ntau pua xyoo.
Cov kav dej tooj liab yog qhov kev xaiv kim thiab txhim khu kev qha rau kev sib txuas cov kav dej. Cov hlau muaj tus nqi siab, tab sis nws ruaj khov, tsis xeb, thiab tshuaj tua kab mob dej. Tsis tas li ntawd, cov kav dej tooj liab tsis tuaj yeem muab zais, tab sis hloov mus rau hauv kev kho kom zoo nkauj sab hauv tiag tiag. Nrog rau qhov décor, chav dej yuav saib lub teeb, stylish thiab ruaj khov.
Cov kav dej ua los ntawm cov polymers muaj zog zoo li cov kav hlau, lawv yog lub teeb yuag, yooj yim rau solder, yog li kev thauj mus los thiab kev teeb tsayuav tsis ntaus tus neeg siv khoom hauv hnab ris. Lawv tuaj yeem siv ob qho tib si sab hauv thiab sab nraum lub tsev. Vim lub elasticity, lawv tiv taus lub caij ntuj no frosts.
Cov ntaub ntawv ntim rau cov kav dej ua haujlwm
txhawm rau kom lub raj xa dej ua haujlwm yam tsis muaj qhov xau, nws yog ib qho tsim nyog yuav tsum siv cov ntaub ntawv sib khi ruaj khov thiab ruaj khov. Yog tsis muaj lawv, txawm tias kim tshaj plaws thiab high-tech qauv yuav tsis muaj peev xwm ua haujlwm ib txwm. Txhua yam ntawm cov ntaub ntawv sealing yog tsim los tiv thaiv kev sib tshuam ntawm cov kav dej. Cov ntsaws ruaj ruaj siv rau mounting sau cov micro-voids ntawm sab hauv thiab sab nraud ntawm qhov chaw thiab yog li tiv thaiv kev nkag mus ntawm dej. Lub ntsiab lus yooj yim tshaj plaws ntawm cov kav dej yog cov pob qij txha.
Muaj cov kav dej nrog cov xov tshwj xeeb uas tsis tas yuav tsum tau siv cov khoom siv sib khi. Nyob rau hauv catalogs ntawm loj kev tsim kho tsev loj thiab khw muag khoom tshwj xeeb muaj xws li kev xaiv. Thaum txuas ob qhov hlau, ib qho kev ruaj ntseg seam yog tsim vim lub cev qhuav dej ntawm threaded coil. Txawm li cas los xij, hauv qhov no nws yuav tsis tuaj yeem disassemble thiab sib sau ua ke yog tias tsim nyog, yog li cov kav dej no tsis tshua siv.
Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws
Cov no yog cov khoom uas txuas cov kav dej ntawm qhov khoov, khoov, ceg lossis qhov sib txawv ntawm cov khoom sib txuas. Cam khwb cia hlau threaded fittings - cov khoom siv kav dej ntau tshaj plaws, lawv yog siv rau cov kav dej ua los ntawm cov cam khwb cia hlau lossis hlau. Nrogntawm sab hauv, cov ntsiab lus yog threaded, ua tsaug uas lawv raug mob.
Adhesive fittings yog tsau nrog kua polymer. Nrog lawv pab, kev teeb tsa tau ua tiav sai li sai tau, thiab kev sib txuas yog nruj.
Kev ntsuas tus kheej ntawm tus kheej yog ib qho kev tsim kho tshiab. Lawv yog cov mechanically complex, haum rau cov kav dej tooj liab, thiab lawv tus kheej ua los ntawm tooj liab.
Hlau-yas fittings yog npaj tshwj xeeb rau cov kav dej polymer.
Hatches, kho dua
Raws li txoj cai, kev sib txuas lus kav dej nyob hauv chav dej thiab chav dej. Hauv qee lub tsev lawv nyob hauv qhov chaw pom tseeb. Qhov kev daws teeb meem no ua rau kev saib xyuas yooj yim heev, tab sis sab hauv zoo li unaesthetic. Cov khoom siv kav dej thiab cov ntaub ntawv tuaj yeem muab zais tom qab phab ntsa thiab cov thawv ntim qhuav, tab sis qhov no, yuav tsum muab cov kaus mom tshwj xeeb lossis kho dua tshiab.
Tools
Yuav ua haujlwm kav dej, tus tswv yuav tsum muaj cov cuab yeej siv nrog nws. Feem ntau ntawm lawv tuaj yeem siv rau lwm hom kev tsim kho thiab kho cov haujlwm. Cov npe ntawm cov cuab yeej uas yuav tsum tau muaj xws li cov ntsia hlau ntsia hlau, cov cuab yeej hluav taws xob, cov ntaub ntawv, cov wrenches, ncig pom, pliers.
