Lub flanged npauj npaim valve yog ib hom npauj npaim valve ntsia rau hauv cov kav dej ntawm flanged kev sib txuas. Nws lub luag haujlwm tseem ceeb yog tswj qhov nruab nrab ntws los yog ua tiav kaw -tawm los ntawm kev tig lub disc (0℃-90℃). Nws yog dav siv nyob rau hauv cov khoom siv dej / cov kav dej thiab cov kav dej roj rau kev lag luam xws li cov chaw kho dej, cov chaw tsim hluav taws xob, tshuaj, khoom noj, thiab tshuaj.
Cov yam ntxwv zoo
Txoj kev sib txuas
Lub cev lub cev tuaj nrog flanges ntawm ob qho kawg, ncaj qha rau cov kav dej flanges rau kev txhim khu kev ruaj ntseg thiab kev txhim kho yooj yim, tshwj xeeb tshaj yog tsim rau siab - siab thiab loj - daim ntaub ntawv txoj kab uas hla.
Piv nrog rau wafer- hom npauj npaim li qub, flanged versions tsis vam khom flange compression, muab kev ruaj ntseg dua sealing thiab ywj siab disassembly rau kev kho.
Valve Lub Cev Tsim
Tsim los ntawm casting los yog forging los xyuas kom meej lub zog txaus thiab rigidity los tiv thaiv pipeline nruab nrab siab.
Streamlined internal kab noj hniav tsim minimizes kua kuj thiab turbulence, txhim khu kev txaus txaus thiab txo lub zog noj.
Disc Structure
Lub disc yog ib lub voj voog lossis elliptical nyias phaj uas tig ib ncig ntawm nws axis los tswj qhov nruab nrab ntws.
Cov ntaub ntawv muaj xws li stainless hlau, tooj liab, nylon, roj hmab -coated, los yog PTFE, xaiv raws li kev ua haujlwm.
High- qauv tsim kawg siv ob lossis peb npaug ntawm cov qauv eccentric kom tshem tawm kev sib txhuam, txuas ntxiv lub neej kev pabcuam, thiab hloov mus rau qhov xwm txheej hnyav (piv txwv li, ultra- kub / siab).
Hom sealing
Soft Seal
Khoom siv: Nitrile roj hmab (NBR), EPDM, fluororubber.
Nta: Kev sib khi zoo heev tab sis tsis tshua muaj qhov kub thiab txias (tsawg dua lossis sib npaug li 65 degree), haum rau qis - kub / qis- cov ntawv thov siab (dej, roj, roj).
Daim ntawv thov: Dej / dej ntws, HVAC, zaub mov / tshuaj lag luam.
Hard Foob
Khoom siv: Stainless hlau los yog cobalt-raws li nyuaj alloy welded rau lub rooj / disc sealing nto.
Nta: High-kub tsis kam (tsawg dua lossis sib npaug li 550 degree), siab -siab (txog PN25+), lub neej ntev, tab sis me ntsis qis dua sealing piv rau cov ntsaws ruaj ruaj.
Daim ntawv thov: Hnyav tej yam kev mob nyob rau hauv tshuaj, roj, thiab chav pipelines.
Composite Foob
Qauv: Laminated hlau los xij (piv txwv li, hloov tau graphite + stainless hlau).
Nta: Muab qhov zoo ntawm cov ntsaws ruaj ruaj thiab mos, yoog rau siab - kub, siab - siab, thiab corrosive media.
Daim ntawv thov: Cua sov, roj, roj, thiab kua qaub/alkali pipelines.
Txoj Cai Ua Haujlwm
Qhib/Closing Control
Lub disc tig 0℃-90℃nyob ib ncig ntawm lub qia kom tso cai los yog thaiv qhov nruab nrab ntws.
Thaum qhib tag nrho, lub disc thickness yog qhov tsuas yog tsis kam, kom ntseeg tau tias tsawg kawg nkaus siab poob thiab zoo heev khiav tswj.
Sealing Mechanism
Soft Seal: Lub nplhaib foob elastically deforms nyob rau hauv nruab nrab siab kom kaw tawm tsam lub disc.
Hard Foob: Ob chav / triple eccentric tsim cais lub rooj zaum thiab disc thaum lub sijhawm ua haujlwm kom tshem tawm kev sib txhuam thiab ua tiav xoom xau.
Daim ntawv thov Scenario
Cov xwm txheej
Dej / fais fab nroj tsuag: Tswj dej ntws thiab tiv thaiv kom tsis txhob ntws.
Kev lag luam tshuaj: Tswj qhov sib piv ntawm corrosive media.
Khoom noj / Pharmaceutical: Ua kom muaj purity nruab nrab thiab tsis txhob kis kab mob.
Cov xwm txheej tshwj xeeb
High-Tsub/High-Pressure: Cov kav dej hauv cov roj / metallurgy.
Corrosive Media: Acid/alkali pipelines los yog seawater systems (siv corrosion{0}}cov ntaub ntawv tiv taus zoo li stainless hlau los yog PTFE-lined).
Bidirectional Sealing: Pump discharge check li qub los tiv thaiv rov qab.
