Txhua yam uas nquag siv valve xya txoj kev saib xyuas me me valve tsev kawm ntawv nug: tsev neeg feem ntau siv valve yuav daim ntawv ceeb toom

Txhua yam uas nquag siv valve xya txoj kev saib xyuas me me valve tsev kawm ntawv nug: tsev neeg feem ntau siv valve yuav daim ntawv ceeb toom Valve hauv kev tsim khoom, lub neej nyob rau hauv txhua qhov chaw ntawm lub neej yog siv heev, yog cov kav dej hauv tsev, cov kav dej hauv cov kav dej indispensable. Raws li me me raws li cov kav dej hauv tsev, loj npaum li Peb Gorges Dam, Qinshan nuclear fais fab nroj tsuag, thiab txawm tias Shenzhou series spacecraft thiab International Space Station, li qub ua lub luag haujlwm tseem ceeb hauv nruab nrab. Yog li kev siv lub valve yuav tsum tau them sai sai rau kev saib xyuas, lub valve hauv kev siv cov txheej txheem, yuav tsum nquag ua kom huv si, kev sib kis xov yuav tsum tsis tu ncua lubricated, pom qhov txhaum, yuav tsum tsis txhob siv tam sim ntawd, nrhiav kom paub qhov ua txhaum. Valve nyob rau hauv industrial ntau lawm, lub neej nyob rau hauv tag nrho cov mus taug kev ntawm lub neej yog siv heev, yog lub domestic dej pipeline, muaj kua pipeline indispensable ntaus ntawv. Raws li me me raws li cov kav dej hauv tsev, loj npaum li Peb Gorges Dam, Qinshan nuclear fais fab nroj tsuag, thiab txawm tias Shenzhou series spacecraft thiab International Space Station, li qub ua lub luag haujlwm tseem ceeb hauv nruab nrab. Yog li ntawd, lub valve yuav tsum tau xyuam xim rau kev saib xyuas, hais txog kev saib xyuas, koj puas paub yuav ua li cas tswj lub valve? Xya txoj kev kho ntawm lub valve yog raws li hauv qab no: 1, lub valve nyob rau hauv tus txheej txheem ntawm kev siv, yuav tsum nquag ntxuav, kis xov yuav tsum tsis tu ncua lubricated, pom muaj txhaum, yuav tsum tam sim ntawd tsis txhob siv, nrhiav kom paub qhov ua txhaum. 2, packing gland bolts yuav tsum tau nruj nreem sib npaug, yuav tsum tsis txhob nias rau hauv lub xeev crooked, thiaj li tsis txhob muaj kev puas tsuaj los cuam tshuam qia txav los yog ua rau to. 3. Thaum txhim kho, lub valve tuaj yeem ntsia ncaj qha rau ntawm cov yeeb nkab raws li hom kev sib txuas. GENERAL, nws tuaj yeem nruab rau hauv txhua txoj haujlwm ntawm cov raj xa dej, tab sis nws yuav tsum yooj yim rau kev khiav lag luam, ua tib zoo saib xyuas qhov ntws ntawm lub ntiaj teb valve nruab nrab yuav tsum nyob rau hauv lub longitudinal valve disc upward, nqa check valve tsuas yog yuav tsum tau. ntsia kab rov tav. 4, npauj npaim valve, pob valve, lub ntiaj teb valve, lub rooj vag valve, tsuas yog qhib los yog kaw tag nrho, tsis txhob tso cai rau kho qhov ntws, kom tsis txhob muaj qhov sib khi nto yaig, ua kom hnav. Lub rooj vag valve thiab cov xov xov ntiaj teb sab saud muaj cov cuab yeej sib khi, thiab lub log tau tig mus rau sab saum toj kom nruj nws, uas tuaj yeem tiv thaiv cov xov xwm los ntawm kev ntim khoom. 5, npauj npaim valve, pob valve, lub ntiaj teb valve, lub rooj vag valve qhib thiab kaw daim ntawv thov ntawm tes, tsis txhob siv cov levers lossis lwm yam cuab yeej, kom tsis txhob ua kom puas lub valve. Tig lub handwheel clockwise kom kaw, vice versa qhib. 6. Ua ntej kev teeb tsa, nws yuav tsum ua tib zoo xyuas lub siab ntawm lub valve, seb txoj kab uas hla raws li qhov yuav tsum tau siv, tshem tawm qhov tsis xws luag los ntawm kev thauj mus los, thiab tshem tawm cov av ntawm lub valve. 7 li qub, lub sijhawm ntev cia, yuav tsum tau kuaj xyuas tsis tu ncua, rau cov dej ntws ntawm qhov chaw ua haujlwm yuav tsum huv, av, cia thiab xaus thaum lub pob valve yuav tsum tau thaiv hauv qhov qhib, npauj npaim valve, lub rooj vag valve, lub ntiaj teb valve, check valve, qhov kawg ntawm cov channel yuav tsum tau thaiv thiab kaw, zoo zoo khaws cia nyob rau hauv tsev thiab ventilated qhov chaw qhuav, tsis txhob heap los yog nyob rau hauv qhib cua. Lub tsev kawm ntawv me me tau nug: tsev neeg feem ntau siv lub valve yuav daim ntawv ceeb toom thaum xaiv qhov muag pom lub valve, qhov chaw yuav tsum tsis muaj trachoma; Electroplating nto yuav tsum yog ib yam luster, yuav tsum xyuam xim rau seb puas muaj tev, tawg, hu nkauj, nthuav tawm hauv qab, tev, dub me ntsis thiab pom tseeb pitting tsis xws luag; Cov tshuaj tsuag saum npoo yuav tsum zoo, du thiab sib xws, tsis muaj qhov tsis xws luag xws li ntws dai thiab nthuav tawm hauv qab. Civil li qub feem ntau yog siv los ntawm cov tsev neeg zoo tib yam nyob rau hauv daim ntawv ntawm lub rooj vag li qub, pob li qub, daim duab peb sab li qub, thiab lwm yam, feem ntau yog ua los ntawm hlau los yog tooj liab. Vim tias cov khoom siv zoo ntawm cov tooj liab alloy, nws muaj qhov zoo ntawm qhov tsis yooj yim rau xeb thiab muaj zog corrosion kuj, yog li cov tooj liab valve tau maj mam hloov cov hlau valve Thaum yuav khoom ntawm qhov muag tshuaj xyuas valve, qhov saum npoo yuav tsum tsis muaj trachoma; Electroplating nto yuav tsum yog ib yam luster, yuav tsum xyuam xim rau seb puas muaj tev, tawg, hu nkauj, nthuav tawm hauv qab, tev, dub me ntsis thiab pom tseeb pitting tsis xws luag; Cov tshuaj tsuag saum npoo yuav tsum zoo, du thiab sib xws, tsis muaj teeb meem xws li ntws dai thiab nthuav tawm hauv qab. Civil li qub feem ntau yog siv los ntawm cov tsev neeg zoo tib yam nyob rau hauv daim ntawv ntawm lub rooj vag li qub, pob li qub, daim duab peb sab li qub, thiab lwm yam, feem ntau yog ua los ntawm hlau los yog tooj liab. Vim tias cov khoom siv zoo ntawm tooj liab alloy, nws muaj qhov zoo ntawm qhov tsis yooj yim rau xeb thiab muaj zog corrosion kuj, yog li cov tooj liab valve tau maj mam hloov cov hlau valve. Daim duab peb sab valve nto yog qhov pib siv electroplating, nws lub luag haujlwm tsis yog tsuas yog tswj cov dej ntws nruab nrab, tab sis kuj ua lub luag haujlwm zoo nkauj. Daim duab peb sab valve feem ntau txuas nrog cov kav dej thiab cov dej nkag hose rau cov dej nozzle, cov dej hauv chav dej, thiab tseem txuas nrog cov kav dej thiab cov dej nkag hose rau cov dej rhaub dej. Lub rooj vag li qub yog siv los txuas cov kav dej thiab cov ntsuas dej. Pob valve rau piping thiab dej rhaub kev sib txuas. Vim tias lub pob valve qhib thiab kaw yog yooj yim dua li lub rooj vag valve, feem ntau ntawm cov kav dej thiab cov ntsuas dej txuas nrog lub pob li qub. Kev yuav khoom ntawm pej xeem valve: Ntau hom pej xeem li qub yuav tsum raug xaiv raws li qhov sib txawv ntawm cov neeg siv khoom: 1. Kev soj ntsuam lub valve thaum yuav khoom, thiab qhov chaw yuav tsum tsis muaj trachoma; Electroplating nto yuav tsum yog ib yam luster, yuav tsum xyuam xim rau seb puas muaj tev, tawg, hu nkauj, nthuav tawm hauv qab, tev, dub me ntsis thiab pom tseeb pitting tsis xws luag; Cov tshuaj tsuag saum npoo yuav tsum zoo, du thiab sib xws, tsis muaj qhov tsis xws luag xws li ntws dai thiab nthuav tawm hauv qab. Cov teeb meem no yuav cuam tshuam ncaj qha rau lub neej kev pab cuam ntawm lub valve. 2. Cov yeeb nkab xov ntawm lub valve yog txuas nrog cov kav dej, qhov pom tseeb tsis xws luag xws li concave cim, cov hniav tawg tau pom nyob rau saum npoo ntawm cov xov thaum xaiv thiab yuav, tshwj xeeb tshaj yog cov uas yuav tsum tau ceeb toom yog cov ntsia hlau ntawm cov yeeb nkab xov thiab cov khoom sib txuas kaw. ntev ntev yuav cuam tshuam qhov kev ntseeg ntawm kev sib khi, qhov ntev ntawm cov yeeb nkab xov yuav tsum tau pom thaum xaiv thiab yuav. General DN15 lub tog raj kheej yeeb nkab xov ntev ntev li ntawm 10mm. 3. Lub rooj vag li qub thiab pob li qub feem ntau yog cim nrog lub siab nominal ntawm lub valve lub cev lossis kov, uas tuaj yeem xaiv raws li lawv tus kheej xav tau. 4. Thaum hloov lub rooj vag valve lossis pob valve, xyuas kom meej tias nws cov qauv ntev yog qhov tseeb kom nws tsis tuaj yeem ntsia tom qab yuav khoom. 5. Daim duab peb sab valve yeeb nkab xov muaj ob hom xov sab hauv thiab sab nraud xov, raws li qhov yuav tsum tau xaiv; Daim ntawv ceeb toom dab tsi txawm tias yog daim duab peb sab VALVE uas muaj ib feem ZINC ALLOY los ua hauv khw tam sim no, lub valve no tus nqi xav qis dua li cov khoom siv dav dav, tab sis yooj yim corrosion thiab ua rau tawg. Yuav tsum nyob rau hauv kom deb li deb tau raws li qhov tsim nyog cov khoom siv hauv tsev khw, SUPERMARKET xaiv thiab yuav, cov khoom zoo li no tuaj yeem paub ntau ntxiv.
