Sdv valve (kaw lub valve)
Kev piav qhia
Lub sdv valve (kaw qhov hluav taws xob) yog lub valve nrog v-puab qhib ntawm ib sab ntawm ib nrab-pob lig. Los ntawm kev kho qhov qhib ntawm lub lig, cov ntoo khaub lig-ntu ntawm cov ntws nruab nrab tau hloov pauv los kho cov ntws. Nws kuj tseem siv tau rau hloov tswj kom paub qhov qhib lossis kaw ntawm cov raj xa dej. Nws muaj kev tu tus kheej, tuaj yeem ua tiav qhov kev nyab xeeb me me hauv ntau yam qhib me me, haum rau fiber ntau, haum rau fiber ntau, cov lus zoo, slurry media.
Qhov qhib thiab kaw ib feem ntawm V-hom pob pob valve yog ib tug kheej nrog cov ciav hlau ncig, thiab ob lub hemispheres tau txuas los ntawm lub qhov rooj thiab tig mus ua tiav lub hom phiaj ntawm kev qhib thiab kaw.
Nws yog dav siv nyob rau hauv lub tshuab tsis siv neeg ntawm roj av, kev lag luam tshuaj thiab lwm yam.

✧ Cov yam ntxwv ntawm SDV valve (kaw lub valve) (v chaw nres nkoj)
1. Cov kua dej tsis kam yog me, cov ntws mefficient loj, cov kho tau yooj yim yog qhov siab. Nws tuaj yeem ncav cuag: 100: 1, uas loj dua li cov sib piv kho ntawm ncaj ib leeg-rooj kev tswj hwm valve, ob-rooj kev tswj hwm valve thiab lub tes tsho tswj valve. Nws cov yam ntxwv ntws yog feem pua sib npaug.
2. Txhim Kho Txiaj Ntsig. Cov to freakage qib ntawm cov hlau nyuaj tsim qauv yog chav kawm IV ntawm GB / T4213 "Pneumatic tswj Valve". Qhov qib qis ntawm cov qauv foob muag mos yog V lossis chav VI ntawm GB / T4213. Rau cov qauv sib zog, cov pob tub ntxhais sib khi ua saum npoo yuav ua tau los ntawm cov roj ntsha tawv nqaij, txau cov khoom siv ntawm lub neej ntawm lub valve core corne.
3. Qhib thiab kaw sai sai. V-hom pob valve yog qhov qhib lub valve, los ntawm kev qhib kaw tag nrho 90 °, nruab nrog ntawm Piston Pneumatic Actuator tuaj yeem siv rau kev txiav ceev. Tom qab kev txhim kho hluav taws xob valve txoj hauj lwm, nws tuaj yeem hloov kho raws li cov teeb liab analog 4-20mA piv.
4. Kev thaiv kev ua tau zoo. Cov kab surps 1/4 hemispherical cov duab nrog cov qauv rooj zaum uas tsis muaj rooj tshuam. Thaum muaj cov khoom muaj nyob hauv nruab nrab, cov kab ke thaiv yuav tsis tshwm sim zoo li o-hom pob li qub. Tsis muaj qhov sib txawv ntawm lub pob V-puab thiab lub rooj zaum, tshwj xeeb yog tsim nyog rau kev tswj hwm ntawm kev ncua thiab khoom muaj fiber ntau lossis cov khoom me me. Ib qho ntxiv, muaj V-puab lub pob li qub nrog cov kab thoob ntiaj teb, uas yog qhov tsim nyog txo qhov kev cuam tshuam ntawm lub pob ntawm lub pob ntawm cov tub ntxhais siab thaum lub siab sib txawv yog ua. Nws tau txais ib lub rooj sib khi ib zaug lossis ob chav rooj sib khi qauv. Lub pob V-puab lub pob valve nrog ob lub rooj sib khi yog feem ntau siv rau cov kev cai nrawm, thiab nruab nrab nrog cov khoom siv tuaj yeem ua rau muaj kev phom sij ntawm clogging lub kab noj hniav nruab nrab.
5. V-hom pob valve yog tus qauv pob ruaj khov, lub rooj zaum tau thauj nrog lub caij nplooj ntoo hlav, thiab nws tuaj yeem txav mus raws txoj kev ntws. Tuaj yeem cia li them nyiaj rau cov kab kev hnav, ntev ntev lub neej pabcuam. Lub caij nplooj ntoo hlav muaj hexagonal caij nplooj ntoos hlav, yoj caij nplooj ntoos hlav, disc caij nplooj ntoos hlav, cylindrical compressure hlav thiab lwm yam. Thaum nruab nrab muaj impurities me me, nws yog ib qho tsim nyog los ntxiv cov nplhaib sib khi rau lub caij nplooj ntoo hlav los tiv thaiv nws ntawm impurities. Rau ob chav lub rooj sib khi thoob ntiaj teb spool v-pob li qub, lub pob ntab daim tawv.
6. Thaum muaj hluav taws thiab tawm tsam cov qauv hluav taws xob zoo li qub, cov muab tub lim rau ntawm cov khoom siv nyuaj, thiab cov khoom siv hluav taws xob kub, thiab lub valve qia muaj lub xub pwg sib khi. Nqa cov tshuab hluav taws xob daws tau ntsuas nruab nrab ntawm lub cev valve, qia thiab kheej. Ua raws li GB / T26479 Cov qauv hluav taws-resistant thiab GB / T12237 antisticatic yuav tsum muaj.
7. Cov qauv siv ntau yog yog cov xoom eccentric. Cov tsiaj ntawv hauv lub cev tuaj yeem tso tawm cov zaub sai sai tawm sai sai thaum nws qhib, txo cov kev coj ntawm lub nplhaib sib khi thiab txuas ntxiv lub neej pabcuam. Thaum kaw, lub zog eccentric tuaj yeem tsim los txhim kho cov nyhuv seading.
8. Lub tsheb tsav ntawm V-hom pob pob valve muaj hom, cab iav cov iav kis, pneumatic, hluav taws xob hydraulic thiab lwm yam tsav tsheb.
9. Hom pob valve kev txuas txuas tau muaj kev sib txuas Flange thiab clamp spool, ob tog sealing qauv thiab xov txuas vuam, taub qab li lwm txoj kev sib txuas.
10.Qhia pob Valve tseem muaj v-puab pob cov qauv qauv. Zoo hnav tsis kam, tab sis kuj cov kua qaub thiab alkali corrosion tsis kam, ntau haum rau kev tswj ntawm cov xov xwm granular. Cov tshuaj lom lub pob fluorine muaj lub pob V-puab, uas yog siv rau kev tswj hwm thiab tswj kua qaub thiab alkali corrosive. Daim ntawv thov ntau ntawm V-Hom Pob Pob Valve yog ntau dua thiab muaj ntau yam ntxiv.
✧ Kev pab cuam tomqua tom qab muag
Kev pab cuam tom qab muag ntawm SDV valve (kaw qhov chaw nres nkoj (v chaw nres nkoj) yog ib qho tseem ceeb heev, vim tias tsuas yog ua raws sijhawm thiab kev ua haujlwm ntev thiab ruaj khov. Cov hauv qab no yog cov kev pabcuam muag tom qab muag ntawm qee cov pob ntoo ntab:
