1, Txheej txheem cej luam ntawm fluorine lined npauj npaim li qub
PTFE lined npauj npaim valve txais yuav PTFE kab npauj npaim phaj nrog lub ntsej muag kheej kheej. Lub valve yog ib qho yooj yim rau kev khiav lag luam, muaj kev sib khi nruj, thiab lub neej ua haujlwm ntev ntev; Nws tuaj yeem siv rau kev txiav tawm sai sai lossis kho qhov ntws. Haum rau lub sijhawm uas xav tau kev sib khi txhim khu kev qha thiab kev hloov kho zoo. Lub valve lub cev tau txais ib hom kev sib cais, thiab kev sib khi ntawm ob qho kawg ntawm lub valve ncej yog tswj los ntawm kev ntxiv cov roj hmab fluorine rau lub hauv paus rotating nto ntawm tus npauj npaim phaj thiab lub rooj zaum valve; Xyuas kom meej tias lub valve ncej tsis tuaj yeem cuam tshuam nrog cov kua nruab nrab hauv cov kab noj hniav. Dav haum rau kev thauj mus los ntawm cov kua thiab roj (xws li vapors) nyob rau hauv ntau hom kev lag luam kav, thiab siv rau hauv cov xov xwm corrosive hnyav xws li sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine gas, muaj zog alkali, thiab lwm yam corrosive media.
2, Cov yam ntxwv ntawm cov fluorine lined npauj npaim li qub
1. Cov qauv tsim yog tshiab, tsim nyog, thiab muaj cov qauv tshwj xeeb, nrog lub teeb yuag thiab ceev ceev qhib thiab kaw.
2. tuaj yeem ntsia tau rau hauv txhua txoj haujlwm, yooj yim rau kev saib xyuas.
3. Lub sealing caij tuaj yeem hloov tau, thiab kev ua haujlwm sealing yog txhim khu kev qha, ua tiav xoom xau hauv ob qho tib si cov lus qhia.
4. Me me ua haujlwm torque, ua haujlwm yooj yim, txuag zog thiab agile.
5. Cov khoom siv sealing muaj cov yam ntxwv xws li kev laus ua haujlwm, kev tiv thaiv corrosion, thiab lub neej ua haujlwm ntev.
