Lub pneumatic flanged npauj npaim valve belongs rau ib hom pneumatic npauj npaim valve. Nws lub cev valve nta flanges ntawm ob qho kawg. Cov flanges no yog fastened rau yeeb nkab flanges siv bolts. Qhov no tsim endows nws nrog zoo sealing kev ua tau zoo thiab siab siab - bearing muaj peev xwm. Raws li qhov tshwm sim, nws pom cov ntawv thov dav dav hauv cov kav dej muaj qhov nruab nrab - rau - siab siab, cov kav dej loj loj, lossis cov kev cai nruj nruj tam sim no.
Cov yam ntxwv tseem ceeb
Flange Connection: Lub cev valve muaj cov qauv flanges (xws li GB, ANSI, DIN, thiab lwm yam) ntawm ob qhov kawg. Nws txuas nrog cov yeeb nkab flanges los ntawm bolts, thiab sealing gaskets (rubber, hlau qhov txhab gaskets) xyuas kom nruj ntawm lub interface. Qhov zoo: Nws yog haum rau siab - siab (PN16–PN40) thiab loj - txoj kab uas hla (DN50–DN2000) xwm txheej. Nws yog resistant rau vibration thiab loosening, thiab yog ib qho yooj yim rau disassemble thiab tswj.
Pneumatic Actuator: Nws yog nruab nrog ib qho - ua yeeb yam (caij nplooj ntoos hlav rov qab) lossis ob - ua yeeb yam (ob - txoj kev pneumatic tswj) lub tog raj kheej, uas muaj qhov tso zis ntau zog thiab tuaj yeem tsav lub phaj valve kom tig ntawm 0℃mus rau 90℃. Qhov chaw ntse (xws li nrog IP67 tiv thaiv qib) tuaj yeem xaiv tau teeb tsa, txhawb nqa 4-20mA cov cim lossis kev sib txuas lus hauv tsheb npav (PROFIBUS, HART) kom ua tiav qhov kev qhib qhib.
Sealing Design
Mos Sealing: Lub rooj zaum valve yog ua los ntawm EPDM lossis NBR roj hmab, uas haum rau qhov qub - kub (-20 ~ 120 degree) thiab tsis-corrosive media (dej, huab cua, roj). Qhov dej ntws mus txog qib VI (zero to).
Hard Sealing: Nws siv stainless hlau + graphite surfacing lossis hlau - rau - hlau sealing, uas tuaj yeem tiv taus qhov kub thiab txias (tsawg dua lossis sib npaug li 425 degree), kev kub siab thiab cov khoom siv (xws li cov pa, plua plav).
Cim npe nrov: npaum pneumatic flanged npauj npaim valve yog kua dej tswj, Tuam Tshoj, lwm tus neeg, manufacturers, hoobkas, customized, yuav, nqe, kev muag, Tshuag, dawb qauv
