I amashumi amabini anesihlanu taboos yofakelo iimpahla ezomileyo ivalve, wazi kangakanani?

I-valve sesona sixhobo sixhaphakileyo kumashishini ekhemikhali. Kubonakala kulula ukufaka i-valve, kodwa ukuba ayiqhutywa ngokwetheknoloji efanelekileyo, iya kubangela izingozi zokhuseleko. Namhlanje, ndingathanda ukwabelana ngamava kunye nolwazi malunga nokufakelwa kwevalvu. I-Taboo 1 Uvavanyo loxinzelelo lwamanzi luya kwenziwa phantsi kobushushu obungalunganga ngexesha lokwakhiwa kwasebusika. Umphumo: ngenxa yokukhenkceza ngokukhawuleza kumbhobho ngexesha lovavanyo lwe-hydrostatic, umbhobho unqanyuliwe Amanyathelo: uvavanyo loxinzelelo lwamanzi luya kwenziwa ngaphambi kokwakhiwa kwebusika ngokusemandleni, kwaye amanzi aya kuqhunyiswa acoceke emva kovavanyo loxinzelelo, ngakumbi. amanzi akwivalvu kufuneka acocwe, kungenjalo ivalve iya kuhlwa xa ilula, kwaye ikhenkceke ukuqhekeka ukuba inzima. Ngethuba lovavanyo loxinzelelo lwamanzi ebusika, iprojekthi iya kuqhutywa phantsi kweqondo lokushisa elihle langaphakathi, kwaye amanzi aya kuqhunyiswa acoceke emva kovavanyo loxinzelelo. Taboo 2 Isixokelelwano sombhobho asihlanjwa ngononophelo phambi kokuba sigqitywe, kwaye ukuhamba nesantya asinako ukuhlangabezana neemfuno zokugungxulwa kwemibhobho. Ide isebenzise uvavanyo lwamandla okwenziwa ngoxinzelelo lwendalo ukukhupha amanzi endaweni yokugungxulwa. Umphumo: ukuba umgangatho wamanzi uyasilela ukuhlangabezana neemfuno zokusebenza kwenkqubo yombhobho, icandelo lombhobho liya kuncitshiswa okanye livalwe. Imilinganiselo: gungxula ngowona mpompozo uphezulu wejusi oyiliweyo okanye isantya sokuhamba kwamanzi esingekho ngaphantsi kwe-3m/s kwisixokelelwano. Umbala wamanzi kunye nokungafihli kokuphuma kuya kuhambelana naleyo yokungena ngokuhlola okubonakalayo. Taboo 3 Ugutyulo lwamanzi amdaka, amanzi emvula kunye nemibhobho econdelekileyo iya kufihlwa ngaphandle kovavanyo lwamanzi avaliweyo. Isiphumo: kunokubangela ukuvuza kwamanzi kunye nelahleko yomsebenzisi. Imilinganiselo: uvavanyo lwamanzi oluvaliweyo luya kujongwa kwaye lwamkelwe ngokungqongqo kunye neenkcukacha. Ulwandlalo olungaphantsi komhlaba, isilingi, igumbi lombhobho kunye nolunye ugutyulo olufihliweyo, amanzi emvula, imibhobho econdekileyo, njl.njl. ziya kuqinisekiswa ukuba azivuzi. I-Taboo yesi-4 Ngexesha lovavanyo lwamandla e-hydraulic kunye novavanyo lokuqina kwenkqubo yombhobho, kuphela ixabiso loxinzelelo kunye noshintsho lwezinga lamanzi lubonwa, kwaye ukuhlolwa kokuvuza akwanele. Isiphumo: ukuvuza kwenzeka emva kokusebenza kwenkqubo yombhobho, echaphazela ukusetyenziswa okuqhelekileyo. Imilinganiselo: xa inkqubo yepayipi ivavanywa ngokweemfuno zokuyila kunye neenkcukacha zokwakha, ngaphezu kokurekhoda ixabiso loxinzelelo okanye utshintsho lwamanzi ngexesha elichaziweyo, kuyimfuneko ukujonga ngokucophelela ukuba kukho ukuvuza. I-Taboo 5 I-valve flange eqhelekileyo isetyenziswa kwiflange yevalve yebhabhathane. Isiphumo: ubungakanani beflange yevalve yebhabhathane yahlukile kuleyo yeflange yevalvu eqhelekileyo. Enye i-diameter yangaphakathi ye-flange incinci, ngelixa i-disc yevalve yevalve ye-butterfly inkulu, nto leyo ebangela ukusilela ukuvula okanye ukuvulwa kanzima kwaye konakalise ivalve. Imilinganiselo: ipleyiti yeflange iya kucutshungulwa ngokobungakanani beflange yevalve yebhabhathane. I-Taboo 6 Akukho mingxuma egciniweyo kunye neengxenye ezifakwe ekwakhiweni kwesakhiwo sokwakha, okanye ubungakanani beemingxuma ezigciniweyo zincinci kwaye iindawo ezidibeneyo aziphawulwanga. Umphumo: ekwakhiweni kobunjineli obufudumele kunye nococeko, ukutshiza isakhiwo sokwakha, nokusika imivalo yensimbi egxininisiweyo, kuchaphazela ukusebenza kokhuseleko lwesakhiwo. Amanyathelo: ukuqhelana nemizobo yokwakha yeprojekthi yokufudumeza kunye nococeko, ngenkuthalo nangokucokisekileyo ukusebenzisana nokwakhiwa kwesakhiwo sokwakha ukugcina imingxuma kunye neenxalenye ezifakwe ngokweemfuno zofakelo lwemibhobho kunye nezixhaso kunye nokuxhoma, kwaye ubhekiselele iimfuno zoyilo kunye neenkcukacha zokwakha ngeenkcukacha. Taboo 7 Ngexesha lokuwelda kombhobho, emva kokudityaniswa kwempundu, indawo egxadazayo yombhobho ayikho kumgca osembindini, akukho sikhewu sishiywe kwilungu lempundu, akukho groove isikiweyo kumbhobho oshinyeneyo wodonga, kwaye ububanzi nokuphakama kweweld akuhlangani iimfuno zemigaqo yokwakha. Umphumo: ukuba umbhobho awukho kumgca weziko elifanayo, uya kuchaphazela ngokuthe ngqo umgangatho we-welding kunye nomgangatho wokubonakala. Akukho msantsa uya kushiyelwa kwi-butt joint, akukho groove iya kusikwa kumbhobho ongqindilili wodonga, kwaye xa ububanzi kunye nokuphakama kwe-weld kungahlangabezani neemfuno, i-welding ayikwazi ukuhlangabezana neemfuno zamandla. Imilinganiselo: emva kokubambisana kwe-butt yombhobho odibeneyo, umbhobho awuyi kugungqa kwaye ube kumgca ophakathi; i-butt joint iya kunikwa imvume; umbhobho oshinyeneyo wodonga uya kugqutywa. Ukongeza, ububanzi kunye nobude be-weld buya kuxutywa ngokuhambelana nenkcazo. Taboo 8 Lo mbhobho ungcwatywa ngokuthe ngqo kumhlaba onomkhenkce nakumhlaba ongacocwanga, kwaye isithuba kunye nendawo ezimi kuyo imibhobho ayifanelekanga, nokuba kukwimo yezitena ezomileyo. Umphumo: umbhobho wonakaliswe kwinkqubo yokuxinwa kwe-backfill ngenxa yenkxaso engazinzanga, okubangelwa ukulungiswa kwakhona kunye nokulungiswa. Imilinganiselo: umbhobho awusayi kungcwatywa kumhlaba onomkhenkce nakumhlaba ongacocwanga. Umgama ophakathi kweebhuthi uya kuhlangabezana neemfuno zemigaqo yolwakhiwo, kwaye i-pad exhasayo iya kuqiniswa, ngakumbi kujongano lombhobho, ongayi kuthwala amandla okucheba. Iintsinjana zezitena ziya kwakhiwa ngodaka lwesamente ukuqinisekisa imfezeko nokuqina. I-Taboo 9 Izinto eziphathekayo zebholidi yokwandisa ukulungiswa kwenkxaso yombhobho ihlwempuzekile, ububanzi bomngxuma wokufaka i-bolt yokwandisa bukhulu kakhulu okanye i-bolt yokwandisa ifakwe eludongeni lwezitena okanye kwindonga yokukhanya. Umphumo: inkxaso yombhobho ikhululekile, umbhobho ukhubazekile okanye ude uwele. Imilinganiselo: iimveliso ezifanelekileyo kufuneka zikhethwe kwiibholithi zokwandisa. Ukuba kuyimfuneko, iisampulu ziya kuthathwa ukuze zihlolwe kwaye zihlolwe. Ububanzi bomngxuma wokufaka iibholithi zokwandiswa abuyi kuba nkulu kune-2mm yobubanzi obungaphandle beebholiti zokwandiswa. Iibholithi zokwandiswa ziya kufakwa kwizakhiwo eziphathekayo. I-Taboo ye-10 Amandla e-flange plate kunye ne-gasket yokudibanisa umbhobho akwanele, kwaye ibholithi yokudibanisa imfutshane okanye ububanzi buncinci. Iphedi yerabha iya kusetyenziselwa umbhobho wobushushu, ipadi enomaleko kabini okanye ipad yebevel iya kusetyenziselwa umbhobho wamanzi abandayo, kunye neflange ipad iya kuphumela ngaphandle kumbhobho. Isiphumo: uxhulumaniso lwe-flange aluqinanga, kwaye lonakaliswe, kwaye ukuvuza kwenzeka. Xa i-gasket ye-flange iphuma kumbhobho, iya kwandisa ukuchasana nokuhamba. Imilinganiselo: ipleyiti yeflange kunye negasket esetyenziselwa umbhobho kufuneka ihlangabezane neemfuno zoxinzelelo olusebenzayo loyilo lombhobho. Irabha ye-asbestos pad iya kusetyenziselwa i-flange gasket yokufudumeza kunye nemibhobho yokubonelela ngamanzi ashushu; Iphedi yerabha iya kusetyenziselwa i-flange gasket yonikezelo lwamanzi kunye nemibhobho yokuhambisa amanzi. I-gasket ye-flange ayiyi kuphuma kumbhobho, kwaye isangqa sangaphandle siya kufaneleka kwi-bolt hole ye-flange. Akukho pad ethotyiweyo okanye iipads ezininzi ziya kubekwa embindini weflange. Ububanzi bebholiti edibanisa i-flange iya kuba ngaphantsi kwe-2mm kune-diameter ye-flange ye-flange, kwaye ubude be-nut ephumayo yentonga ye-bolt iya kuba yi-1 / 2 ye-nut ubukhulu.
