Cov khoom haum hloov tau-ntsuas qhov kev txiav txim siab valf08-00

Lub rooj vag valve ntawm nyem refrem refers refers valve uas kaw (rooj vag) thiab txav mus los raws cov channel nruab nrab. Lub rooj vag valve yog siv rau kev txiav tawm hauv cov raj xa dej. Rooj vag valve yog dav dav siv rooj vag valve. Nws feem ntau yog siv rau cov khoom txiav tawm nrog DNTCation cov cuab yeej nrog DNE EBUE, qee zaum, cov rooj vag yog siv rau cov khoom txiav me me. Rooj vag li qub muaj cov txiaj ntsig hauv qab no: ① cov kua dej me me. Outing quab yuam yuav tsum tau qhib thiab kaw qhov ncaj-ua yeeb yam nyem valve yog me me. (3) Cov kev taw qhia ntawm cov khoom tsis txwv. (4) Thaum qhib qhov chaw nyob sib khi tsis muaj qhov txawv txav ntawm cov haujlwm ua haujlwm tshaj li kev txiav-tawm valve. Daim duab yog qhov yooj yim heev thiab cov txheej txheem forging yog qhov zoo. Rooj vag li qub kuj muaj qee qhov shortcomings: ① Qhov txheeb ze qhov siab thiab cov qib qhib yog qhov loj. Qhov chaw sab hauv tsev yuav tsum muaj rau kev sib dhos yog qhov loj. ② Thaum qhib thiab kaw kev ua haujlwm, muaj kev sib txhuam ntawm cov chaw sib khi, uas yooj yim ua rau kev sib txhuam. ③ Rooj Vag cov li qub yog muaj ob qhov chaw sib khi, uas nyuaj rau kev tsim khoom, txheej txheem, zom. Rooj vag li qub tuaj yeem muab faib ua: (1) Parallel Rooj Vag Qhov Chaw: Cov chaw sib khi tau sib txuas rau txoj kab ntsug, uas yog qhov chaw sib khi tau sib npaug. Hauv Parallel Rooj vag li qub, tus qauv nrog wrust weet yog qhov muaj heev, uas yog, nws muaj ob lub rooj sib dhos ntawm ob lub rooj vag. Lub rooj vag rooj valve no haum rau rooj vag li qub nrog me me uas hla (DN40-300mm) hauv qhov hluav taws xob tsawg. Kuj tseem muaj lub yees duab caij nplooj ntoos hlav nruab nrab ntawm ob lub rams, thiab lub caij nplooj ntoo hlav torsion tuaj yeem ua rau lub zog ua ntej siv zog, uas tau txais kev sib khi ntawm lub tshuab hluav taws xob valomagnetic. (2) npoo rooj vag valve: cov khoom sib khi ntawm cov ces kaum, uas yog, ob lub rooj sib khi khi ib lub rooj vag valve. Lub oblique saib cov ces kaum ntawm cov chaw sib khi yog feem ntau 2 52 ', 5, 5, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, thiab lwm yam rau lub kaum sab xis yog qhov kub ntawm cov khoom. Feem ntau, qhov kub siab dua yog, qhov loj dua qhov kev pom lub kaum ntse ntse yuav tsum tau txo qhov tshwm sim ntawm kev sib tw ntawm kev hloov pauv.
