Cov ntsiab lus tseem ceeb rau kev khaws cia lub valve fittings yog kev tiv thaiv noo noo, tiv thaiv xeb, tiv thaiv deformation, thiab tiv thaiv kev puas tsuaj. Lub hom phiaj yog los tiv thaiv kev ua tau zoo ntawm cov fittings thiab tiv thaiv kev laus, corrosion, deformation, thiab breakage thaum lub sij hawm cia, kom ntseeg tau ib txwm ua hauj lwm thaum lub sij hawm tom ntej installation thiab siv. Cov kev xav tau tshwj xeeb khaws cia yog raws li hauv qab no:
Cia ib puag ncig yuav tsum tau:
1. Qhov chaw yuav tsum qhuav thiab zoo -ventilated, nrog cov txheeb ze av noo tswj qis dua 60%. Tsis txhob ntub qhov chaw uas tuaj yeem ua rau cov hlau fittings rau xeb thiab sealing fittings rau hnub nyoog thiab muag muag. Qhov chaw cia khoom yuav tsum nyob deb ntawm qhov chaw dej, chav dej, thiab cov roj corrosive (xws li acidic lossis alkaline gases) kom tsis txhob ya raws thiab corrosion. Kev cia hauv qhov chaw qhib - huab cua, ntub dej, lossis plua plav yog txwv nruj. Yog tias qhib ib ntus - huab cua cia yog qhov tsim nyog, tsim nyog los nag, dej noo- pov thawj, thiab kev ntsuas plua plav (xws li npog nrog cov ntaub los nag lossis qhwv nrog cov hnab plua plav).
2. Lub ambient kub yuav tsum tsim nyog, tswj ntawm -5℃thiab 35 degree. Tsis txhob kub siab lossis qis qis uas tuaj yeem ua rau cov fittings puas. Qhov kub thiab txias tuaj yeem ua rau cov khoom sib khi (rubber, PTFE) kom muaj hnub nyoog, soften, thiab deform; Qhov kub tsis tshua muaj peev xwm ua rau cov roj hmab fittings tawg thiab hlau fittings ua nkig, cuam tshuam rau kev ua haujlwm.
3. Qhov chaw cia khoom yuav tsum huv thiab zoo, tsis muaj cov khib nyiab, roj stains, thiab corrosive impurities los tiv thaiv impurities los ntawm adhering rau ntawm qhov chaw, uas yuav ua rau xeb thiab hnav. Qhov no kuj pab txhawb nqa thiab tswj cov khoom.
