Kev Piav Qhia Luv:

Lubpeb lub eccentric npauj npaim valve— tseem hu ua triple offset butterfly valve — yog lub valve npauj npaim hlau uas muaj kev ua haujlwm siab uas tsim los rau kev siv siab, kub siab, thiab zaus siab uas cov valve mos mos ib txwm siv tsis tau. Peb qhov geometric offsets tshem tawm txhua qhov kev sib txhuam ntawm disc thiab lub rooj zaum thaum qhib thiab kaw, ua rau lub rooj zaum tsis hnav ib lub voj voog. Lub rooj zaum yog qhov tseem ceeb rau lub cev valve, coated nrog cov ntaub ntawv tiv thaiv kev hnav thiab lub kaum sab xis zoo tshaj plaws, thaum ntau txheej mos lossis hlau-rau-hlau sealing nplhaib tau tsau rau ntawm lub disc — muab kev tiv thaiv zoo dua rau thermal shock, siab siab, thiab corrosion. Tsim rau API 609, ntsej muag-rau-ntsej muag ANSI B16.10, siab-kub ib ASME B16.34. Qhov ntsuas siab ANSI Chav Kawm 150/300/600/900. Qhov loj me ntau yam DN50–DN1500 (2″–60″). Cov ntaub ntawv lub cev suav nrog carbon hlau, stainless hlau, Monel, thiab Hastelloy. Cov kev xaiv rooj zaum: ntau txheej mos mos foob lossis hlau-rau-hlau. Nortech yog lub tuam txhab tsim khoom thiab muag khoom ntawm triple eccentric butterfly valve hauv Suav teb.

Triple Eccentric Butterfly Valve — Kev Qhia Ua Ntej

Lub Triple Eccentric Butterfly Valve yog dab tsi?

Lubpeb lub eccentric npauj npaim valve— tseem hu ua triple offset butterfly valve — yog lub valve ua haujlwm siab uas tsim los rau kev siv siab, kub, thiab zaus siab. Txawm hais tias cov valve roj hmab concentric muaj kev ntseeg siab thiab tus nqi tsim nyog rau kev pabcuam dav dav, lawv tsis haum rau cov xwm txheej hnyav xws li kub siab lossis kev ua haujlwm siab heev. Cov valve npauj npaim ib txwm muaj uas ruaj khov daws tau qee qhov kev txwv no, tab sis lawv qhov kev ua haujlwm sealing hauv qab cov xwm txheej nyuaj tau ua rau muaj kev txhawj xeeb yav dhau los. Lub valve npauj npaim triple eccentric tau tsim tshwj xeeb los kov yeej cov kev txwv no.

Lub rooj zaum yog ib feem tseem ceeb ntawm lub cev valve, nrog rau lub kaum sab xis zoo tshaj plaws thiab cov txheej tiv thaiv kev hnav uas haum rau ntau lab lub voj voog ua haujlwm. Kev tsim kho hlau tsis xeb muab kev tiv thaiv xeb, thiab cov ntaub ntawv kub siab muaj rau cov chaw kub hnyav. Cov nplhaib sib khi mos mos ntau txheej lossis cov nplhaib sib khi hlau tawv tau kho rau ntawm lub disc, ua rau lub valve tiv taus kev poob siab thermal, siab siab, thiab xeb ntau dua li cov npauj npaim li qub.

Tsis muaj qhov xau dej los ntawm lub nplhaib sib khi ua los ntawm cov hlau tsis xeb uas tau teeb tsa rau ntawm lub disc. Lub geometry peb sab eccentric tshwj xeeb ua rau lub kaum sab xis tig tsis muaj kev sib txhuam - tshem tawm txhua qhov kev sib cuag ntawm lub rooj zaum thiab lub nplhaib sib khi thoob plaws 90 ° stroke. Qhov no txo qhov kev ua haujlwm torque, ua rau lub actuator me dua thiab pheej yig dua.

Thaum kaw, lub tshuab kis tau lub zog nce ntxiv kom muab kev sib khi nruj thiab them rov qab. Lub tshuab no tib lub sijhawm txhim kho kev ua haujlwm ntawm kev sib khi thiab ntev lub neej kev pabcuam ntawm lub valve.

Tus qauv tsim triple offset

1

Lub qhov valve nyob tom qab lub disc centerline, uas ua rau lub nplhaib sealing kaw tag nrho rau ntawm lub rooj zaum valve yam tsis muaj kev cuam tshuam.
2

Qhov nruab nrab ntawm lub qhov valve yog offset los ntawm ob qho tib si lub yeeb nkab nruab nrab thiab lub qhov valve nruab nrab, tshem tawm kev cuam tshuam thaum qhib thiab kaw.
3

Lub axis ntawm lub rooj zaum hloov ntawm qhov chaw nruab nrab ntawm lub qhov valve, tshem tawm kev sib txhuam thoob plaws hauv qhov stroke tag nrho thiab ua tiav kev sib khi sib npaug thoob plaws lub rooj zaum.
