Mos Foob Npauj Npaim Valve
Txoj Cai Ua Haujlwm Ntawm Npauj Npaim Valve
Npauj npaim valve yog lub valve uas qhib thiab kaw los ntawm kev tig lub valve qia thaum tsav lub disc kom tig. Nyob rau hauv lub cylindrical channel ntawm npauj npaim valve lub cev, lub disc-zoo li tus npauj npaim phaj rotates nyob ib ncig ntawm lub axis, feem ntau rotating lub disc 90 degree rau ntws tswj. , thaum lub disc ncav cuag 90 degree, lub valve yog nyob rau hauv ib tug tag nrho qhib lub xeev. Nyob rau tib lub sijhawm, lub kaum sab xis ntawm lub disc tuaj yeem hloov kho qhov nruab nrab ntws. Nws yog feem ntau ntsia rau hauv txoj kab uas hla ntawm cov yeeb nkab. Npauj npaim valve thiab lub valve qia lawv tus kheej tsis muaj peev xwm kaw tau. Yuav kom kho tus nqi ntws tau zoo, yuav tsum muaj tus cab iav reducer. Lub npauj npaim valve nruab nrog cov cab iav reducer tsis tsuas yog ua rau npauj npaim valve nws tus kheej-xauv, tab sis kuj hloov pauv kev ua haujlwm ntawm npauj npaim valve thiab tswj qhov nruab nrab txaus tus nqi ntau dua.
Pre-installation Instructions Rau Wafer Npauj Npaim Valve
1. Ua ntej kev teeb tsa thiab kev ua haujlwm, siv cov tshuaj tsuag cua kom tshem tawm cov khoom txawv teb chaws ntawm cov kav dej, thiab ntxuav cov kav dej nrog dej huv.
2. Ua tib zoo xyuas seb qhov kev siv lub valve puas yog raws li nws qhov kev ua tau zoo; (kub, siab)
3. Tshawb xyuas seb puas muaj cov khib nyiab hauv lub valve channel thiab sealing nto, thiab tshem tawm lawv raws sijhawm;
4. Lub valve yuav tsum tau muab ntsia tam sim tom qab unpacking, thiab thov tsis txhob loosen tej fastening screws los yog ceev ntawm lub valve ntawm yuav;
5. Wafer-hom npauj npaim li qub yuav tsum siv tshwj xeeb npauj npaim valve flanges.
6. Cov hluav taws xob npauj npaim valve tuaj yeem ntsia tau rau ntawm cov kav dej ntawm txhua lub kaum sab xis. Rau qhov yooj yim ntawm kev txij nkawm, nws raug pom zoo kom tsis txhob nruab nws upside down.
7. Thaum txhim kho tus npauj npaim valve flange, koj yuav tsum xyuas kom meej tias lub flange nto thiab cov roj hmab sealing zoo sib xws, cov ntsia hlau tau nruj sib npaug, thiab lub sealing nto yuav tsum haum tag nrho; Yog hais tias cov screws raug nruj tsis sib npaug, cov roj hmab bulges yuav tshwm sim los thaiv cov npauj npaim phaj, los yog saum lub phaj npauj npaim. Kev tuav lub phaj npauj npaim ua rau cov pa tawm ntawm lub valve qia.
Cov lus qhia rau kev siv Damper Valve
1. Nyob rau hauv lub smelting tej yam kev mob nrog kub siab thiab loj plua plav cov ntsiab lus, tus tsim ntawm lub qhov cua npauj npaim valve yuav txais yuav ib tug ca inclined phaj qauv. Muaj qhov sib txawv ntawm tus npauj npaim phaj thiab lub valve lub cev ntawm cov qauv no. Tus nqi sib txawv nyob ntawm lub valve caliber thiab txheej txheem. Cov xwm txheej ntawm kev siv yog txiav txim siab, thiab feem ntau tswj tau nyob rau hauv 0.5% ntawm nws cov channel cheeb tsam, uas tuaj yeem ua tau raws li kev teeb tsa ntawm lub qhov cua npauj npaim li qub, kub hloov pauv hauv kev ua haujlwm, thiab cov txheej txheem melting yuav tsum tau ua.
2. Nyob rau hauv cov kua qaub-ua hauj lwm tej yam kev mob siab kub thiab tsis tshua muaj plua plav cov ntsiab lus, lub qhov cua npauj npaim valve tuaj yeem tsim nrog cov qauv phaj ntsug. Lub sealing nto ntawm cov qauv no yog ib qho yooj yim rau txheej txheem, thiab sealing nto qhov sib txawv tus nqi yog tswj nyob rau hauv 0.2% ntawm cov channel cheeb tsam. Qhov tseeb qhov tseeb ntawm lub cev valve thiab npauj npaim phaj foob khub tuaj yeem ua tau raws li cov qauv tsim los ntawm kev ua haujlwm txhua yam.
3. Rau kev ua haujlwm nrog qhov kub thiab txias, tsis tshua muaj siab thiab nruj sealing yuav tsum tau, lub qhov cua npauj npaim valve yog tsim los txais yuav ib tug lever-hom planar qauv. Lub sealing khub configuration thiab npauj npaim phaj khiav trajectory tuaj yeem ua tau raws li cov txheej txheem ntawm cov khoom siv hauv cov yeeb nkab nrog kev ua haujlwm siab sealing.
Cov lus qhia ua ntej kev teeb tsa ntawm Wafer Npauj Npaim Valve
Ua ntej kev teeb tsa thiab kev ua haujlwm, siv cov tshuaj tsuag cua kom tshem tawm cov khoom txawv teb chaws ntawm cov kav dej, thiab ntxuav cov kav dej nrog dej huv.
Ua tib zoo xyuas seb qhov kev siv lub valve puas ua raws li nws cov kev ua tau zoo; (kub, siab)
Xyuas seb puas muaj cov khib nyiab hauv lub valve channel thiab sealing nto, thiab tshem tawm lawv raws sijhawm;
Lub valve yuav tsum tau nruab tam sim ntawd tom qab unpacking, thiab tsis txhob loosen tej fastening screws los yog ceev ntawm lub valve ntawm yuav;
Wafer npauj npaim li qub yuav tsum siv tshwj xeeb npauj npaim valve flanges.
Lub tshuab hluav taws xob npauj npaim valve tuaj yeem ntsia tau rau ntawm cov kav dej ntawm txhua lub kaum sab xis. Rau qhov yooj yim ntawm kev txij nkawm, nws raug pom zoo kom tsis txhob nruab nws upside down.
Thaum txhim kho tus npauj npaim valve flange, koj yuav tsum xyuas kom meej tias lub flange nto thiab cov roj hmab sealing zoo sib xws, cov ntsia hlau tau nruj tusyees, thiab lub sealing nto yuav tsum haum tag nrho; Yog tias cov ntsia hlau tau nruj tsis sib npaug, cov roj hmab protrusions yuav tshwm sim los thaiv lub phaj npauj npaim, lossis tiv thaiv lub phaj npauj npaim. Lub phaj ua kom cov pa tawm ntawm lub valve qia.
