Kos rau lub sijhawm hloov chaw thiab cov lus nug
Thaum twg los hloov lub ntsuas ntsuas valve?
Kev Pabcuam Lub Neej thiab Kev Tshuaj Ntsuam Xyuas Ib Yam
Ib txwm pab lub neej: High - Zoo saib cov neeg tsim tau 5-10 xyoo tab sis yuav tsum tau ntsuas raws li kev ua haujlwm.
Cov kev pabcuam luv luv lub neej nyob rau hauv cov chaw muaj kev kub ntxhov, kev tshuaj ntsuam xyuas ntau yam muaj cov neeg sawv cev hauv cov neeg sawv cev, pom zoo txhua 3 rau xyoo thiab hloov yog tias tsim nyog. Piv txwv, chav ua noj xyuas cov chav ua noj tej zaum yuav xav tau hloov ntau dua yog tias lawv raug roj thiab haus luam yeeb ntev.
Kev ua phem rau degradation: Yog tias kev sib khi uas tsis zoo (piv txwv li, eg, jamming), corrosion kuj, thiab lwm yam, yuav tsum tau hloov nyob rau lub sijhawm.
Yuam kev ua txhaum
BackFlow: Qhov rov qab los ntawm chav ua noj ntxhiab lossis roj yuav tshwm sim los ntawm tus kos valve tsis ua haujlwm.
Qhov kev puas tsuaj tseem ceeb: tawg valve lub cev, disc distortion lossis laus foob (piv txwv li cov roj hmab tsis tawv thiab tawg).
Cov nqi kho ntau dhau: Yog tias cov nqi kho tau zoo rau lossis tshaj tus nqi ntawm lub valve tshiab, hloov ncaj qha hloov pauv tau.
Kev Hloov Pauv Hluav Taws Xob Hauv Cov Teeb Meem Tshwj Xeeb
Kev hloov kho cov kab ke: Thaum cov piping yog hloov kho lossis khoom siv hloov, kos valve yuav tsum tau hloov nyob rau tib lub sijhawm kom paub tseeb tias kev sib raug zoo.
Kev Nyab Xeeb Kev Nyab Xeeb: Roj Pipeline xyuas cov dej xau yuav ua rau tawg, yuav tsum tau hloov tam sim ntawd.
Ii. Cov Lus Nug thiab Cov Ntsiab Lus
Tawv Cov Teeb Meem
Vim li cas: Kev laus foob, tsis tsim nyog disc / lub rooj nruab nrog, tawg valve lub cev.
Kev daws teeb meem:
Hloov cov ntsaws ruaj ruaj (piv txwv li, cov roj hmab rings, graphite gaskets) los xyuas kom meej cov qauv sib xws.
Grind disc thiab lub rooj zaum sib khi los kho cov khawb lossis deformations.
Kos lub cev lub cev ncaj ncees thiab hloov cov li qub.
Qhib / Kaw
Cov laj thawj: Cov kab thaiv hnyav, valve discormation, lossis hnav cov lus qhia kev tsheb nqaj hlau.
Kev daws teeb meem:
Tshem tawm valve thiab tshem tawm sab hauv av (piv txwv li vuam slag, xeb).
Yog lossis hloov deformed disc thiab kho cov lus qhia lub tes tsho.
Thov lube (roj) kom txav chaw (piv txwv li qia).
Suab ntau dhau
Cov laj thawj: ntau tshaj xov xwm ntws, kev xaiv valve tsis zoo, lossis teeb meem kev teeb tsa.
Kev daws teeb meem:
Txhim kho cov raj xa hluav taws xob tsim los txo cov kev ntws (piv txwv li nce cov kab uas hla).
RefsSess valve tus qauv thiab hloov lub xov tooj valve haum rau kev ua haujlwm (piv txwv li lub qhov txhab ntsiag to. Txheeb xyuas cov kev taw qhia ntawm kev teeb tsa tau sib xws nrog cov kev taw qhia ntawm nruab nrab thiab tsis txhob thim kev teeb tsa.
Valve tsis hauj lwm (tsis tuaj yeem kaw / qhib)
Vim li cas: caij nplooj ntoos hlav lov, disc thiab tog misalignment, lossis nruab nrab siab kev txawv txav.
Kev daws: Hloov lub caij nplooj ntoo hlav lossis disc los kho lub rooj zaum ntsuas lub rooj sib co.
Kuaj xyuas yog tias nce nce toj siab tshaj lub valve tus nqi rated (PN). Nruab qhib lub valve valve yog tias tsim nyog.
Rau ntsug khees xyuas li qub, nco ntsoov cov xov xwm ntws yog `` hauv qab rau saum ''.
Kev co thiab dej rauj
Vim li cas: Pulsating Flow (piv txwv li nyob ze cov twj tso dej) lossis chav kaw hluav taws xob.
Kev daws: Nyob deb ntawm daim lev twj tso kua mis (pom zoo kom deb dua lossis sib npaug rau 5 zaug strawb strawb) thiab zam kev teeb tsa ze rau lub qhov cub li qub.
Ib lub rauj rab phom tshem tawm cov roj av tau txhim kho hauv cov kav dej loj loj (khiav ntau dua lossis sib npaug rau 200).
Xaiv kaw qhov ntsuas ntsuas kom qeeb kom txo tau kev cuam tshuam kaw.
III. Txij Nkawm Lus Taw Qhia
Niaj Hnub Tu
Cov chav ua noj / Chav Dej Kuaj Xyuas Li Qub: Tshem tawm thiab ntxuav txhua 1-2 lub hlis, siv cov txhuam muag muag kom tshem cov roj lossis hmoov av.
Kev Tshawb Fawb Kev Lag Luam Valve: Sab Hauv Kev Tawm Tawm Tau Raug Tshem Tawm thiab Polished txhua 1-2 xyoos.
