Dab tsi yog PTFE Lined Street Valve
PTFE Lined Kab Npauj Npaim Valve Muaj Peev Xwm FluoroploraTheej (FEP) lossis PolyperfLuororoethylene Propylene (FEP) nyob rau sab hauv phab ntsa thiab kev sib khi ntawm lub cev. Nws cov qauv tseem ceeb nta polytetrafluoroethylene (PTFE) lossis disc, cais tawm ntawm nruab nrab ntawm cov hlau sib xyaw thiab ua tiav corrosion tsis kam.
Lub valve no nta ib lub disc uas tig ncig nws axis, nrog kev sib hloov lub kaum sab xis ntawm 0℃mus rau 90 degree. Nws muaj qhov tsis tshua pom tsis kam thiab kev ua yeeb yam zoo tshaj plaws. Nws tuaj yeem hloov kho rau cov neeg txawj ntse nrog cov neeg muaj hluav taws xob lossis cov kev tswj hwm kev txhawb nqa rau viscous lossis party. Cov khoom muaj nyob rau hauv Center-Foob thiab ntau hom ntawm eccentric raws cov qauv sib khi. Lawv tau ua raws li cov qauv xws li GB / T 12238 thiab ua haujlwm nyob rau qhov kub thiab txias los ntawm -20℃rau 160 degree. Lub PTFE hauv ob sab phli tiv dhau kev tawm tswv yim zoo heev xws li muaj cov sulfuric acid thiab hydrochloric acid, tswj kev ruaj khov txawm tias muaj mob hnyav.
Nws yog dav siv ua lub raj xa dej tawm thiab ntws tswj hwm, muab cov nqi sib txuas ua haujlwm tau zoo rau cov kua hlau stainless thiab haum rau kev siv nrog cov ntshav ua kom haum.
Dab tsi yog epdm npauj npaim valve
EPDM Npauj Npaim Valve yog hais txog npauj npaim valve ua los ntawm Epdm roj hmab raws li cov khoom sealing. Cov khoom siv no muaj zoo corrosion tsis kam, kev laus tsis kam thiab elasticity tsis zoo thiab kev pabcuam lub neej ntawm npauj npaim valve.
Dab tsi yog EPDM Npauj Npaim Valve thiab PTFE Npauj Npaim Valve?
| Nta | EPDM Foob Npauj Npaim Valve | PTFE Foob Npauj Npaim Valve |
|---|---|---|
| Qhov ntsuas kub ntau | -40 Degree -120 Qib (Lub Sij Hawm Ntev) | -20 Degree -180 Qib (luv luv-lub sijhawm ntev nce 200 degree) |
| Tshuaj Kuj | Resistant rau cov kua qaub tsis muaj zog, alkalis, ozone, thiab yooj yim corroded los ntawm Ketone cov kuab tshuaj | Tiv taus cov kua qaub muaj zog, alkalis qub, thiab cov kuab tshuaj organic (suav nrog Aquara Regia) |
| Kev txhuam cev coefficient | Nruab nrab (pub rau ntawm Elastic Deformation sealing) | Tsawg heev (0.04), txo qhov qhib thiab kaw lub zog torque |
| Cov Khoom Siv Neeg Kho Tshuab | Siab elasticity, yooj yim kom rov qab nyob rau hauv lub siab | Siab tawv, yooj yim rau nkag mus rau hauv nyob rau hauv kev ntxhov siab ntev |
