Mina Ama-taboos angamashumi amabili nanhlanu okufakwa kwe-valve yezimpahla ezomile, wazi kangakanani?

I-Valve iyithuluzi elivame kakhulu emabhizinisini amakhemikhali. Kubonakala kulula ukufaka i-valve, kodwa uma ingenziwanga ngokuvumelana nobuchwepheshe obufanele, izodala izingozi zokuphepha. Namuhla, ngithanda ukwabelana ngolwazi oluthile nolwazi mayelana nokufakwa kwama-valve. I-Taboo 1 Ukuhlolwa kwengcindezi yamanzi kuzokwenziwa ngaphansi kwezinga lokushisa elibi ngesikhathi sokwakhiwa kwasebusika. Umphumela: ngenxa yokuqhwanda okusheshayo kwepayipi ngesikhathi sokuhlolwa kwe-hydrostatic, ipayipi iqhwa Izinyathelo: ukuhlolwa komfutho wamanzi kuzokwenziwa ngaphambi kokwakhiwa kwasebusika ngangokunokwenzeka, futhi amanzi azoshaywa ahlanzeke ngemva kokuhlolwa kwengcindezi, ikakhulukazi. amanzi ku-valve kufanele ahlanzwe, ngaphandle kwalokho i-valve izogqwala uma ilula, futhi iqhwa iqhwa uma inzima. Ngesikhathi sokuhlolwa kwengcindezi yamanzi ebusika, iphrojekthi izokwenziwa ngaphansi kokushisa okuhle kwangaphakathi, futhi amanzi azoshaywa ahlanzekile ngemva kokuhlolwa kwengcindezi. I-Taboo 2 Uhlelo lwamapayipi aluwashwa ngokucophelela ngaphambi kokuqedwa, futhi ukugeleza nesivinini akukwazi ukuhlangabezana nezidingo zokushaywa kwamapayipi. Isebenzisa ngisho nokuhlolwa kwamandla we-hydraulic ukukhipha amanzi esikhundleni sokuwasha. Umphumela: uma izinga lamanzi lihluleka ukuhlangabezana nezidingo zokusebenza kwesistimu yamapayipi, ingxenye yamapayipi izoncishiswa noma ivinjwe. Izinyathelo: shayela ngokugeleza okuphezulu kwejusi okuklanyelwe noma izinga lokugeleza kwamanzi elingekho ngaphansi kuka-3m / s ohlelweni. Umbala wamanzi nokukhanyela kwendawo yokuphuma kuzofanelana nalokho kokungena ngokuhlola okubonakalayo. I-Taboo 3 Amapayipi endle, amanzi emvula kanye ne-condensate azofihlwa ngaphandle kokuhlolwa kwamanzi avaliwe. Umphumela: kungase kubangele ukuvuza kwamanzi kanye nokulahlekelwa komsebenzisi. Izinyathelo: ukuhlolwa kwamanzi avaliwe kuzobhekwa futhi kwamukelwe ngokuhambisana nezimfuneko. Ukulandwa okungaphansi komhlaba, usilingi, igumbi lamapayipi kanye nezinye indle efihliwe, amanzi emvula, amapayipi e-condensate, njll. kuyoqinisekiswa ukuthi ngeke kuvuze. I-Taboo 4 Ngesikhathi sokuhlolwa kwamandla e-hydraulic kanye nokuhlolwa kokuqina kwesistimu yamapayipi, kubukwa kuphela inani lokucindezela kanye noshintsho lwezinga lamanzi, futhi ukuhlolwa kokuvuza akwanele. Umphumela: ukuvuza kwenzeka ngemva kokusebenza kwesistimu yamapayipi, okuthinta ukusetshenziswa okuvamile. Izinyathelo: lapho uhlelo lwamapayipi luhlolwa ngokuvumelana nezidingo zokuklama kanye nokucaciswa kokwakhiwa, ngaphezu kokurekhoda inani lokucindezela noma ukuguqulwa kwezinga lamanzi phakathi nesikhathi esibekiwe, kuyadingeka ukuhlola ngokucophelela ukuthi kukhona ukuvuza. I-Taboo 5 I-valve flange evamile isetshenziselwa i-butterfly valve flange. Umphumela: usayizi we-valve flange we-butterfly uhlukile kulowo we-valve flange evamile. Olunye ububanzi obungaphakathi be-flange buncane, kuyilapho i-valve disc ye-butterfly valve inkulu, okuholela ekuhlulekeni kokuvula noma ukuvuleka kanzima futhi kulimaze i-valve. Izinyathelo: ipuleti le-flange lizocutshungulwa ngokuya ngosayizi wangempela we-valve flange ye-butterfly. I-Taboo 6 Azikho izimbobo ezigodliwe kanye nezingxenye ezishunyekiwe ekwakhiweni kwesakhiwo sesakhiwo, noma ubukhulu bezimbobo ezigodliwe zincane kakhulu futhi izingxenye ezishunyekiwe azimakwa. Umphumela: ekwakhiweni kobunjiniyela obufudumele nobuhlanzekile, ukucwilisa isakhiwo sokwakha, ngisho nokusika imigoqo yensimbi egcizelelwe, kuthinta ukusebenza kokuphepha kwesakhiwo. Izinyathelo: jwayelana nemidwebo yokwakha yephrojekthi yokushisa nokuthuthwa kwendle, ubambisane ngenkuthalo nangokucophelela ekwakhiweni kwesakhiwo sokugcina izimbobo nezingxenye ezishumekiwe ngokuya ngezidingo zokufakwa kwamapayipi nezisekelo nama-hangers, futhi ubheke izidingo zokuklama kanye nemininingwane yokwakha ukuze uthole imininingwane. I-Taboo 7 Ngesikhathi sokushiselwa kwepayipi, ngemva kokuhlangana kwezinqe, ijoyinti elinyakazayo lepayipi alikho emugqeni omaphakathi, alikho igebe elisele ekuhlanganyeleni kwezinqe, akukho mgodi usikwa ipayipi eliwugqinsi, futhi ububanzi nokuphakama kwepayipi akuhlangani izidingo zemininingwane yokwakha. Umphumela: uma ipayipi ingekho emgqeni ofanayo ophakathi nendawo, izothinta ngokuqondile ikhwalithi ye-welding kanye nekhwalithi yokubukeka. Asikho igebe eliyoshiywa ekuhlanganyeleni kwezinqe, akukho groove okufanele isikwe ipayipi eliwugqinsi lodonga, futhi lapho ububanzi nokuphakama kwe-weld kungahlangabezani nezidingo, ukushisela akukwazi ukuhlangabezana nezidingo zamandla. Izilinganiso: ngemva kokuhlangana kwezinqe zepayipi elishiselwe, ipayipi ngeke inyakaze futhi ibe emgqeni ophakathi; i-butt joint izonikezwa imvume; umbhobho owugqinsi wodonga uyoklanywa. Ngaphezu kwalokho, ububanzi nobude be-weld buzoshiswa ngokuhambisana nokucaciswa. Taboo 8 Ipayipi ligqitshwa ngokuqondile enhlabathini eqandisiwe kanye nomhlabathi oxegekile ongalungiswanga, futhi ukuhlukana nendawo yezinqe zamapayipi akulungile, ngisho noma kuyisimo sezitini ezomile. Umphumela: ipayipi liyalimala ngesikhathi sokucinana kokugcwalisa ngenxa yokwesekwa okungazinzile, okuholela ekusebenzeni kabusha nokulungiswa. Izinyathelo: ipayipi ngeke lingcwatshwe emhlabathini oyiqhwa kanye nomhlabathi oxekethile ongalungiswanga. Ibanga eliphakathi kwezinqenqema lizohlangabezana nezidingo zezichasiselo zokwakha, futhi iphedi elisekelayo lizoqina, ikakhulukazi endaweni okusebenzela kuyo amapayipi, okungeke kube namandla okugunda. Izisekelo zezitini zizokwakhiwa ngodaka lukasimende ukuze kuqinisekiswe ubuqotho nokuqina. I-Taboo 9 Impahla ye-bolt yokunweba yokulungisa ukusekelwa kwepayipi impofu, ububanzi bembobo yokufaka ibholidi yokunweba bukhulu kakhulu noma i-bolt yokwandisa ifakwe odongeni lwezitini noma ngisho nodonga olukhanyayo. Umphumela: ukwesekwa kwepayipi kukhululekile, ipayipi likhubazekile noma liwa. Izinyathelo: imikhiqizo efanelekile kufanele ikhethwe amabhawodi wokunweba. Uma kunesidingo, amasampula azothathwa ukuze ahlolwe futhi ahlolwe. Idayamitha yembobo yokufaka amabhawodi wokunweba akufanele ibe mkhulu kuno-2mm wobubanzi bangaphandle bamabhawodi wokunweba. Amabhawodi okunweba azosetshenziswa ezakhiweni zikakhonkolo. I-Taboo 10 Amandla epuleti le-flange ne-gasket yokuxhunywa kwepayipi akwanele, futhi ibhawodi lokuxhuma lifushane noma ububanzi buncane. Iphedi yerabha izosetshenziselwa ipayipi lokushisa, iphedi enezingqimba ezimbili noma i-bevel pad izosetshenziselwa ipayipi lamanzi abandayo, futhi iphedi ye-flange izophumela epayipini. Umphumela: uxhumano lwe-flange aluqinile, ngisho nokulimala, futhi ukuvuza kwenzeka. Lapho i-gasket ye-flange iphumela epayipini, izokwandisa ukumelana nokugeleza. Izinyathelo: ipuleti le-flange kanye ne-gasket esetshenziselwa ipayipi kufanele ihlangabezane nezidingo zokucindezela kokusebenza komklamo wepayipi. Iphedi ye-asbestos yerabha izosetshenziselwa i-flange gasket yokufudumeza kanye namapayipi okuhambisa amanzi ashisayo; i-rubber pad izosetshenziselwa i-flange gasket yamanzi kanye namapayipi okukhipha amanzi. I-gasket ye-flange ngeke iphumele embhobho, futhi umbuthano wangaphandle uzofaneleka emgodini we-bolt we-flange. Awekho iphedi ethambekele noma amaphedi amaningana azobekwa phakathi kwe-flange. Ububanzi bebhawodi elixhuma i-flange buzoba ngaphansi kuka-2mm kunobubanzi bembobo ye-flange, futhi ubude bentongomane ephumayo yenduku yebhawodi buzoba ngu-1/2 wogqinsi lwamantongomane.
