Kev ua tau zoo thiab daim ntawv thov teb ntawm PTFE lined li qub

Teflon lined valve yog lub valve uas siv polytetrafluoroethylene (PTFE, tseem hu ua Teflon) ua cov khoom sib khi, thiab tau siv dav hauv ntau lub teb vim nws qhov kev ua tau zoo tshwj xeeb. Daim ntawv no yuav qhia txog qhov ua tau zoo thiab daim ntawv thov ntawm plaub-fluorine lined valve.
Ua ntej, qhov ua tau zoo ntawm PTFE li qub
1. Kev tiv thaiv corrosion zoo heev: lub sealing nto ntawm lub teflon valve yog ua los ntawm polytetrafluoroethylene cov khoom, uas muaj cov tshuaj lom neeg ruaj khov thiab muaj peev xwm tiv taus corrosion ntawm cov tshuaj lom neeg feem ntau, nrog rau cov kua qaub muaj zog, alkali, cov kuab tshuaj organic, thiab lwm yam, yog li nws ua tau zoo. zoo nyob rau hauv lub tshav pob ntawm corrosive media tsheb thauj mus los.

2. Tsawg coefficient ntawm kev sib txhuam: PTFE muaj qhov coefficient tsawg heev ntawm kev sib txhuam (0.05-0.1), uas ua rau PTFE valve tuaj yeem ua tiav kev txav mus los thaum qhib thiab kaw, txo cov kev khiav hauj lwm torque thiab txo cov khoom siv zog.

3. Kev tiv thaiv viscosity: polytetrafluoroethylene muaj cov viscosity zoo, uas tuaj yeem tiv thaiv cov khoom los ntawm kev sib khi ntawm qhov chaw sib khi thiab txo cov haujlwm ua haujlwm ntawm lub valve.

4. Kub adaptability: cov khoom sealing ntawm PTFE lined valve tuaj yeem ua haujlwm nyob rau hauv thaj tsam ntawm -200 ° C mus rau 260 ° C rau lub sijhawm ntev, thiab tuaj yeem tiv taus qhov kub thiab txias hauv lub sijhawm luv luv, uas ua rau PTFE lined valve tuaj yeem ua tau. siv rau ntau qhov kub thiab txias.

5. Kev nyab xeeb kev ua tau zoo: Vim tias plaub-fluorine lined valve siv cov khoom tsis yog xim hlau ua lub sealing nto, nws yuav tsis tsim cov khoom tsis zoo txawm tias nyob rau hauv huab cua txias xws li kub thiab kub siab, yog li nws muaj kev ruaj ntseg zoo.

Thib ob, daim ntawv thov teb ntawm lined PTFE li qub
1. Kev lag luam tshuaj: PTFE lined li qub tau siv dav hauv kev lag luam tshuaj, tshwj xeeb tshaj yog nyob rau hauv corrosive media, muaj zog acid thiab alkali ib puag ncig, PTFE lined li qub tuaj yeem ua kom muaj kev nyab xeeb ntawm cov khoom siv thiab txo cov nqi tu.

2. Petroleum kev lag luam: Hauv kev lag luam roj av, PTFE lined li qub feem ntau siv los thauj cov roj, roj av thiab lwm yam xov xwm, thiab nws cov corrosion kuj zoo heev thiab sealing kev ua tau zoo ua rau PTFE lined li qub yog qhov nyiam valve hauv kev lag luam roj av.

3. Kev lag luam kws tshuaj: Kev lag luam kws tshuaj muaj cov kev xav tau siab rau kev huv thiab kev nyab xeeb ntawm cov khoom siv, thiab cov tetrafluorolined valve tsuas yog ua tau raws li cov kev cai no, yog li nws tau siv dav hauv kev lag luam tshuaj.
4. Kev lag luam hauv hluav taws xob: Daim ntawv thov ntawm PTFE lined li qub hauv kev lag luam hluav taws xob feem ntau cuam tshuam txog kev sib kis thiab tswj cov roj purity siab thiab kua, thiab nws cov kev ua tau zoo tuaj yeem ua kom ruaj khov ntawm cov khoom siv hluav taws xob.

6. Kev lag luam khoom noj khoom haus: Vim muaj cov khoom zoo los tiv thaiv viscosity thiab tiv thaiv corrosion ntawm PTFE lined li qub, lawv kuj tau siv dav hauv kev lag luam khoom noj khoom haus, xws li kev ua tau zoo heev hauv kev xa tawm high-viscosity media xws li syrup thiab kua txiv hmab txiv ntoo.

Hauv cov ntsiab lus, PTFE lined li qub tau siv dav hauv ntau lub teb los ntawm kev tsim txiaj ntawm lawv cov txiaj ntsig zoo. Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov teb ntawm PTFE lined li qub yuav nthuav dav ntxiv rau yav tom ntej.
