Lub valve txuas ntxiv tswj hwm thiab ua tiav cov cai tau muab ua haujlwm tsis pub dhau lub sijhawm ua haujlwm raug hu ua qhov muaj nuj nqis yog hu ua tsis muaj kev ywj pheej. Thaum kev ua yeeb yam ntawm lub valve puas lawm, nws yuav yog kev ua tsis zoo yuav tshwm sim.
1. Cov thawv ntim khoom noj
Nov yog lub ntsiab ntawm kev khiav, khiav, dripping, thiab to, thiab nws feem ntau pom hauv cov chaw ua haujlwm.
Cov laj thawj rau lub to frowing lub thawv yog raws li hauv qab no:
Cov khoom siv tsis tau sib xws nrog kev corrosiveness, kub thiab siab ntawm qhov nruab nrab ua haujlwm;
②Thaum txoj kev tsis yog lawm, tshwj xeeb tshaj yog thaum lub pob ntim tag nrho yog muab tso rau hauv ib tug kauv, nws yog feem ntau yuav ua rau to taub;
③hle qhov tseeb lossis saum npoo ntawm lub valve qia yog tsis txaus, lossis muaj ovality, lossis muaj cov nicks;
④THE valve valve tau pitted, lossis xeb vim tsis muaj kev tiv thaiv hauv cov huab cua qhib;
⑤the valve lub kav yog khoov;
⑥THE Packing tau siv ntev ntev thiab muaj hnub nyoog;
Kev ua haujlwm siab heev dhau lawm.
Cov txheej txheem los tshem tawm cov touge yog:
① Kev xaiv yog ntawm Fillers;
②fill nyob rau hauv txoj kev tseeb;
③ Yog tias lub valve qia tsis tsim nyog, nws yuav tsum tau kho lossis hloov chaw, thiab qhov tseem ceeb tshaj plaws, nws yuav tsum ncav cuag ▽ 8 lossis siab dua, thiab tsis muaj lwm yam tsis xws;
Siv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv, thiab cov uas tau xeb yuav tsum tau hloov;
⑤bending ntawm lub valve qia yuav tsum ncaj qha lossis hloov tshiab;
⑥⑥ter Cov ntaub pua ntim tau siv rau qee lub sijhawm, nws yuav tsum tau hloov;
Kev ua haujlwm yuav tsum ruaj khov, qhib maj mam thiab kaw qeeb kom tiv thaiv kev kub sai lossis ntsuas kub.
2. Txhaum ntawm kev kaw ntu
Feem ntau, cov to frowage ntawm lub thawv stuffing yog hu ua kev xau sab nraud, thiab ntu kaw yog hu ua kev xau sab hauv todle. Kev xau ntawm kev kaw, hauv lub valve, tsis yooj yim nrhiav.
Qhov xau xau tuaj yeem muab faib ua ob pawg: ib qho yog qhov xau ntawm cov hauv paus ntawm lub hauv paus ntawm lub nplhaib sealing.
Cov ua rau xau to yog:
①THTHE SEALING DE DEG TSIS ZOO KAWG AV;
②Tus nplhaib sib khi tsis nruj nrog lub rooj zaum hauv lub rooj thiab lub rooj valve;
③THTHTHE PUAS ntawm lub valve disc thiab lub valve kav tsis yog ruaj;
Ruam valve yog khoov thiab sib ntswg, kom cov sab saud thiab qis dua tsis yog chaw;
⑤creepose nrawm dhau lawm, qhov chaw nyob sib khi tsis muaj kev sib cuag lossis tau ntev lawm;
Kev xaiv tsis raug cai, tsis tuaj yeem tiv taus txoj kev xeb ntawm nruab nrab;
⑦ Siv lub ntiaj teb valve thiab lub rooj vag valve raws li kev tswj hwm valve. Lub suab nrov sib khi tsis tuaj yeem tiv thaiv cov yaig ntawm cov hluav taws xob nrawm;
⑧some media yuav maj mam txias tom qab lub valve raug kaw, kom cov saws saum npoo yuav tshwm sim, thiab yaig tseem tshwm sim, thiab kev yaig kuj tshwm sim;
Kev sib txuas tau sib txuas yog siv los ntawm qee qhov chaw sib khi thiab lub rooj zaum valve thiab yooj yim los tsim cov pa taws sib txawv thiab corrode xoob;
⑩THEHE STROUNTLY TAS NRHO RAU LUB EMBEDING NTAWM IMREEDING SISTIVITIES xws li vuam slag, xeb, lossis cov tshuab hluav taws xob hauv cov txheej txheem tsim khoom uas poob thiab thaiv lub valve core.
Cov kev ntsuas tiv thaiv yog:
①before siv, koj yuav tsum ua tib zoo ntsuas lub siab thiab xau, thiab pom cov to suab ntawm lub nplhaib sib khi, thiab tom qab ntawd siv nws tom qab kev kho mob;
②it yog qhov tsim nyog los tshawb xyuas ua ntej seb puas muaj ntau seem ntawm ntau seem ntawm lub valve muaj kev mob zoo. Tsis txhob siv lub valve uas lub valve qia yog khoov los yog sib ntswg lossis lub valve disc thiab lub valve qia tsis txuas ruaj ntseg;
③thethe lub valve yuav tsum raug kaw kom ruaj, tsis yog sib ceg. Yog tias koj pom tias qhov kev sib tiv tauj ntawm cov chaw sib khi tsis zoo lossis muaj kev cuam tshuam rau nws kom tau txais cov khib nyiab kom zoo, thiab tom qab kaw kom zoo;
④whath xaiv lub pob valve, tsis tsuas yog corrosion tsis kam ntawm lub cev valve, tab sis kuj tseem cov corrosion tsis kam ntawm qhov chaw kaw yuav tsum tau txiav txim siab;
⑤ Raws li cov qauv kev tsim qauv ntawm lub valve thiab siv tau, cov khoom siv uas yuav tsum tau kho cov kev ntws yuav tsum siv lub valve regulating;
⑥for qhov teeb meem no yog qhov txias txias thiab qhov kub kub tau loj tom qab kaw lub valve, lub valve yuav tsum kaw kom nruj me ntsis tom qab txias;
⑦whad lub rooj valve, lub nplhaib valve thiab cov nplhaib sib txuas nrog cov xov, PTFE daim kab xev tuaj yeem siv los ua cov xov ntawm cov xov, kom tsis muaj qhov sib txawv;
Kev lim dej yuav tsum tau ntxiv rau pem hauv ntej ntawm lub valve rau lub valve uas yuav poob rau kev impurities.
3. Valve qia nyom tsis ua hauj lwm
Cov laj thawj rau lub valve kav li li txhawb tsis ua tiav yog:
Txoj xov no puas ntsoog vim muaj kev ua haujlwm ntau dhau;
② Tsis muaj lubrication lossis roj nplua nyeem tsis ua hauj lwm;
③THE VALVAL STAL yog khoov thiab sib ntswg;
④THTHTHE TAM SIM NO TSIS TAWM;
Qhov haum kom ua siab ntev yog tsis muaj tseeb, thiab kev tom yog nruj heev;
Ruam valve txiv ntoo yog inclined;
Kev xaiv tsis zoo, piv txwv li, lub valve qia thiab lub valve kav qia yog ua los ntawm tib cov khoom, uas yog qhov yooj yim rau tom;
Xov tau corroded los ntawm nruab nrab (hais txog lub valve nrog lub maub lub valve lossis lub valve nrog qia txiv ntoo rau hauv qab);
ETHLHTHTHTHY XAV TXOG-AIRVE AV Tsis muaj kev tiv thaiv, thiab lub pob valve tab yog them nrog hmoov av thiab xuab zeb, lossis xeb los ntawm cov nag, lwg, te thiab daus.
Txoj kev tiv thaiv:
① Ua kom zoo saib xyuas lub sijhawm, tsis txhob yuam kev thaum kaw, tsis txhob ncav cuag qhov nruab nrab ntawm qhov nruab nrab ntawm kev thawb lub pob hluav taws xob los ntawm kev cuam tshuam rau kev cuam tshuam;
②CHIK Lubrication puas nquag thiab ua kom lub xeev lubrication qub;
Tsis txhob qhib thiab kaw lub pob valve nrog tus qib ntev. Cov neeg ua haujlwm uas tau yoog raws li siv qib luv yuav tsum tswj hwm tus nqi tiv thaiv nrog lub pob zeb ncaj qha txuas nrog lub pob zeb ncaj qha txuas nrog lub pob zeb ncaj qha rau kev sib txuas thiab lub zog valve);
④④prove zoo ntawm kev ua lossis kho kom tau raws li cov kev cai tshwj xeeb;
Cov ntaub ntawv yuav tsum tau tiv taus corrosion thiab hloov kho kom txias thiab lwm yam kev ua haujlwm;
⑥THE KAB KHW KHWV YUAV TSUM TSIS TXHOB UA RAU COV KHOOM ZOO LI CAS AS VALVE LUJ;
⑦ Thaum siv cov yas raws li lub valve cov txiv ntseej, lub zog yuav tsum tau kuaj xyuas, tsis yog qhov teeb meem me me, tab sis kuj yog lub zog, yog tias lub zog tsis txaus, tsis txhob siv nws;
⑧THE VALVER HLUB tiv thaiv yuav tsum tau muab ntxiv rau qhov qhib cua valve;
Feem ntau qhib lub valve, tig mus rau tes mus rau lub valve qia los ntawm xeb.
4. Lwm yam
Gasket tokage:
Qhov laj thawj tseem ceeb yog tias nws tsis tiv taus corrosion thiab tsis yoog rau kev ua haujlwm kub thiab siab; Thiab qhov ntsuas kub hloov ntawm qhov ntsuas kub kub.
Siv Gaskets tsim rau cov kev ua haujlwm. Tshawb xyuas seb cov roj av gasket haum rau cov li qub tshiab. Yog tias nws tsis haum, nws yuav tsum tau hloov. Rau cov ntsuas kub siab, ua kom nruj lub bolts dua thaum siv.
Nrib pleb valve lub cev:
Feem ntau tshwm sim los ntawm khov. Thaum huab cua txias, lub valve yuav tsum muaj kev rwb thaiv tsev thermal thiab kev ntsuas kub. Txwv tsis pub, cov dej hauv lub valve thiab txuas txoj kev txuas rau tom qab tsim (yog tias muaj qhov ntsaws rau hauv qab ntawm lub valve, cov ntsaws yuav qhib tau).
Puas Handwheel:
Tshwm sim los ntawm kev cuam tshuam lossis kev ua haujlwm ntawm kev ua haujlwm ntev. Nws tuaj yeem zam tau ntev li ntev tau yog tus neeg teb xov tooj thiab lwm tus neeg muaj kev txhawj xeeb ua tib zoo mloog.
Cov pob zeb ntim tau tawg:
Tsis ncaj ncees thaum compressing ntim, lossis cov caj pas tsis zoo (feem ntau cam khwb cia hlau). Hlob cov packing, tig lub ntsia hlau symmetrically, thiab tsis skew. Thaum tsim khoom, tsis tsuas yog yuav tsum them sai sai rau cov chaw loj thiab tseem ceeb, tab sis tseem tseem yuav them sai sai rau qhov chaw theem nrab xws li nws yuav cuam tshuam rau kev siv.
Kev sib txuas ntawm lub valve qia thiab lub valve phaj tsis:
Lub rooj vag valve admts kev sib txuas ntawm lub taub hau sib txuas ntawm lub rooj sib dhos ntawm lub rooj vag yog qee zaum tsis ua tiav, yog li lub taub hau sib dhos ntawm lub valve qia ntoo sai. Feem ntau yog los ntawm kev tsim khoom ntiag tug los daws. Txawm li cas los xij, tus neeg siv kuj tuaj yeem ua kom lub z-puab zawj kom nws muaj qee lub smoothness.
Lub rooj vag ntawm ob chav rooj vag valve tsis tuaj yeem nias lub hau npog kom nruj:
Lub nro ntawm ob lub rooj vag yog tsim los ntawm cov nqaj saum toj kawg nkaus. Rau qee lub rooj vag li qub, wedge sab saum toj yog cov khoom siv tsis zoo (qis-qib cam khwb cia hlau), thiab yuav hnav lossis tawg sai sai tom qab siv. Lub wedge sab saum toj yog ib daim me me, thiab cov khoom siv tsis ntau. Tus neeg siv tuaj yeem ua rau nws nrog cov hlau hlau thiab hloov cov thawj hlau cam khwb cia.
