I-valve yamapayipi njengengxenye ebalulekile yesistimu yenqubo. Izinga lokufakwa kwe-valve yamapayipi linquma ngokuqondile ukufezeka okuhle kwemisebenzi ehlobene yohlelo lwenqubo. Izixhumanisi zokulawula eziyinhloko zabaphathi bayo zimi kanje:
1, ukuhlolwa kwe-valve nokwamukelwa
1.1 Ukuhlolwa kokubukeka kwamavalvu: azikho izimbotshana, i-trachoma, imifantu nokugqwala emzimbeni wamavalvu; Isiqu asigobi, isenzakalo sokugqwala, intambo ye-stem ibushelelezi, icocekile ngaphandle kocingo oluphukile; Indlala ngokuzungeza okuhle, okuguquguqukayo kwesondo lesandla; Indawo yokubeka uphawu ye-Flange ngaphandle kokuklwebheka, ama-pockmark, njll.; Ukuxhumeka kwentambo kusesimweni esihle; I-welding groove efanelekayo. Inombolo yebhithi ye-valve, ingcindezi kanye neminye imingcele ihambisana nomklamo.
1.2 Ukuhlolwa kwemibhalo: Amadokhumenti ikakhulukazi ahlanganisa: ipulani yekhwalithi, ubufakazi bempahla, imidwebo eyakhiwe, amarekhodi okuhlola, amamanuwali okunakekela, izidingo zokugcinwa, kanye nesitifiketi sokuvumelana. Amavalvu angavumelani kufanele abe nemibhalo ehambisanayo yokukhululwa enemibandela kanye namapuleti okuhlonza angahambisani nebhizinisi.
2. Izidingo zokugcinwa kwe-valve nokugcinwa kwazo
Gcina i-valve yokungena kanye ne-outlet ivaliwe futhi ubeke i-desiccant, shintsha njalo ngokusho kwemiyalelo ye-desiccant. Nquma izinga lokushisa, umswakama kanye nezidingo zemvelo zokugcinwa ngokuvumelana nemibhalo yokulungisa ama-valve. Kumavalvu ensimbi engagqwali, qaphela ukukhetha izinto zokugoqa ezingezona i-halogen. Ama-valve kufanele ahlolwe futhi agcinwe njalo ngesikhathi sokugcina.
3, ukuhlolwa kwengcindezi ye-valve
Ngenxa yokuthi i-valve yenziwe igobolondo, isihlalo kanye nokuhlolwa kwengcindezi yokuvala ngaphambi kokushiya imboni, yenza kuphela ukuhlolwa kokuvala kwe-valve esizeni. Ngobubanzi nengxenye yokuqinisekisa, izinga likazwelonke le-GB50184-2011 lichaza ingxenye yokuhlolwa kwengcindezi yasensimini, izindinganiso zangaphandle azinazo izidingo. Ngokuvamile umnikazi unqunywa ngokuya ngokugadwa kwekhwalithi kanye nesipiliyoni sokusebenzisa sesiteji sokukhiqiza ama-valve, futhi ivalvu evamile idinga ukuvalwa ngo-100% ensimini.
3.1 Izidingo eziphakathi kokuhlola: indawo yokuhlola i-valve ngamanzi; Sebenzisa amazinga ahlukene ekhwalithi yamanzi ngokuya ngokuhlanzeka kohlelo; Kodwa-ke, lapho isisetshenziswa se-valve siyigesi, indawo yokuhlola ikhethwa ukusebenzisa umoya ocindezelwe ongenawo uwoyela owomile noma i-nitrogen, futhi ingathathelwa indawo umfutho wamanzi.
3.2 Ukunqunywa kokucindezela kokuhlolwa kokuvala: Izidingo zokuvala ukucindezela kokuhlolwa kwamavalvu ku-GB/T13927-2008 kanye ne-ASME B16.34 kanye ne-MSS-SP-61 ngokuyisisekelo ziyafana. I-HYDROSTATIC TEST PRESURE IYIZIKHATHI EZINGU-1.1 IZIKHATHI OKULINGANISWE ESIKALASI SOkucindezela I-VALVE EKU-100OF, NOMA UKUHLOLA OKUPHANSI NGAPHANSI KWAMA-80psi OKUNGENZEKA KUSETSHENZISWA. Lapho I-valve NAMEplate IMAKA NGOMEhluko OMKHULU WOKUCINDEZELA WOKUSEBENZA NOMA indlela YOKUSEBENZA ye-valve ayifanele ukuhlolwa komfutho wokuvalwa komfutho ophezulu, Ukucindezela kokuhlola kungenziwa ngokuvumelana nezikhathi ezingu-1.1 zomehluko omkhulu wengcindezi yokusebenza ephawulwe nge- i-valve nameplate.
3.3 Ukuhlolwa kwemiphumela yokuhlolwa: Incazelo yokuhlola yokuvala ivalvu idinga kuphela ukuhlola ukuthi kuhlale isikhathi esifushane kakhulu, futhi asikho isidingo esikhethekile sokuvala isivivinyo isikhathi esingekho ngaphansi kwemizuzu emi-5 ekusebenzeni kwangempela. I-valve evalwe ngezinto eziguquguqukayo ngeke ibe nokuvuza okubonakalayo futhi akukho kwehla kwengcindezi yegeji yokucindezela phakathi nesikhathi sokubamba ingcindezi. EZINXENYENI ZOKUDIYIKA IVAVVU EVUMELA UKUVUZA, I-USSS INGASE IKALA NGOKUQONDILE UKUVUZA NGESIKHATHI SESIKHATHI SESIKHATHI SESIKHATHI NOMA ISEBENZISE INANI LAMABHHUBHU NOMA AMADHOSHA AMANZI NJENGOBA KUCHAZWE KUHLOKO LWE-MSS-SP-61. Ukuvuza KUhlobene nobubanzi obujwayelekile be-valve. Imfuneko yokuvuza yezinga likazwelonke iyafana naleyo yezinga laseMelika.
I-1 2 ngaphakathi kwe-valve yepayipi likawoyela negesi ukuvuza isizathu nokwahlulela kudlala indawo encishisiwe ekusebenzeni kwe-valve kumapayipi kawoyela negesi, isiqondiso sokugeleza kokusabalalisa okuphakathi, indima ebalulekile ekulawuleni ingcindezi, i-valve * * ukukhiqizwa komthelela ovamile Izinkinga zokuphepha ukuvuza, ukuvuza kwe-valve ngaphandle kwamacala amabili ngokulandelana kwawo ukuvuza kwe-valve (ukuvuza) nokuvuza kwangaphakathi (ukuvuza). Uma ingatholakali futhi kubhekwana nayo ngesikhathi, kuzoba nezingozi ezinkulu zokuphepha, ezingase zithinte ukuphepha kokukhiqizwa kokuthutha uwoyela negesi nokusebenza kanye nokugcinwa nokulungiswa kwemishini. Lapho i-valve ivuza, ungalalela indawo yesehlakalo, uhlole ukuthi kukhona ukuvuza kwemidiya okusobala nokunye okutholwe enembile, kodwa futhi ungasebenzisa igesi evuthayo.
I-valve idlala indima ebalulekile ekusebenzeni kwamapayipi kawoyela negesi, njengokunqamula okuphakathi, ukusabalalisa isiqondiso sokugeleza kwe-medium, ukulawula ingcindezi nokunye. Inkinga evamile ethinta ukuphepha kwe-valve ukuvuza. Izimo ezimbili zokuvuza kwe-valve ukuvuza kwangaphandle kwe-valve (okubizwa ngokuthi ukuvuza kwangaphandle) kanye nokuvuza kwangaphakathi (okubizwa ngokuthi ukuvuza kwangaphakathi). Uma ingatholakali futhi kubhekwana nayo ngesikhathi, kuzoba nezingozi ezinkulu zokuphepha, ezingase zithinte ukuphepha kokukhiqizwa kokuthutha uwoyela negesi nokusebenza kanye nokugcinwa nokulungiswa kwemishini. Lapho i-valve ivuza, ungalalela umsindo ngaso leso sikhathi, uhlole ukuthi kukhona yini ukuvuza okusobala kwemidiya nokunye okutholwe ngokunembile, kodwa futhi ungasebenzisa umtshina wegesi ovuthayo noma ithuluzi lokubona ukuvuza ukuze lihlolwe futhi libonwe. Ngemuva kokuvuza kwe-valve, ukucasha okujwayelekile kunamandla, akutholakali ngesikhathi, kulula ukwenzeka ukugcwala kwengcindezi, ukungcoliswa kukawoyela nezinye izingozi zokukhiqiza ukuphepha, njengokuvela kwe-inter-string yemidiya ehlukene, uphahla lwethangi lokugcina uwoyela, imishini ephansi yomfula ayikwazi zilungisiwe, njll., imiphumela mibi.
Isizathu sokuvuza kwangaphakathi kwe-valve
1.1 Inkinga yomkhawulo wokushintsha
Isizathu esibaluleke kakhulu esiholela ekuvuzeni kwe-valve ukuthi ukulungiswa komkhawulo wokushintsha akukho endaweni. ISINYATHELO sokuqala ESOKUNIKA ukuvuza kwe-valve ukuhlola ukuthi i-valve switch isendaweni yini, ikakhulukazi ukubona ukuthi ivalvu ingavaleka ngokugcwele yini endaweni yayo. Ama-valve amaningi ebhola asendaweni egcwele, izingxenye zokuvala ibhola kanye nomzimba we-valve zidinga kuphela ukwehluka ngamadigri angu-2 ~ 3, kuzodala ukuvuza kwe-medium. Ngenxa yokuthi i-valve yepulaki inciphise ububanzi, ngakho izingxenye zokuvala ezijwayelekile kanye nomehluko womzimba we-valve we-10-15 degrees kuzodala ukuvuza kwangaphakathi. Ngokuvamile kubangela ukuthi umkhawulo wokushintshwa kwe-valve ungekho endaweni ikakhulukazi okubangelwa izimo ezilandelayo:
(1) Ivalvu ifakwa efekthri noma ngesikhathi sokuthuthwa nokulayisha nokuthulula, okuholela ekuxhumekeni kwesiqu se-valve kanye nokuhlanganiswa komkhono we-valve I-engeli yokuchezuka okuholela ekuphambukeni komkhawulo okuholela ekuvuzeni kwangaphakathi;
(2) ukuhlanganisa i-valve ye-valve yesethi yamabhulokhi, kanye nokugqitshwa ngenxa yesiqu eside, njengoba ukukhula kokusetshenziswa kwesikhathi, ukugqwala kwesiqu se-valve nokunye ukungcola kungene esimweni esiphansi sesethi, ube phakathi kwesiqu se-valve kanye nesethi ye-valve amabhlogo anqwabelene okunye ukungcola okunjengothuli, isihlabathi, ukugqwala, upende, okwakhiwa ku-valve evala ivalvu ayikwazi ukufakwa endaweni yokuvuza;
(3) I-actuator engazange inakekelwe isikhathi eside, ngenxa yokuwohloka kwamafutha asebhokisini legiya abe amabhulokhi aqinile, ukugqwala okunqwabelanayo, amabhawodi axegayo kanye nezinye izizathu, kuzodala ukuchezuka komkhawulo futhi kubangele i-valve ngaphakathi. ukuvuza;
(4) ivalvu ene-actuator isethwe indawo egcwele yokuvala isithuthuke kakhulu, kuvalvu empeleni ayivalwanga ngokugcwele ukuze kumiswe isenzo, okuholela emngceleni ongalungile futhi kubangele ukuvuza kwangaphakathi;
(5) Ivalvu ikhishwa ngokungafanele, futhi ukungcola kunqwabelana egumbini levalvu, okuholela ekutheni ivalvu ingakwazi ukuvalwa ngokuphelele endaweni futhi kubangele ukuvuza kwangaphakathi;
(6) Ngesikhathi sokusebenza, ukungcola ku-tube kungena phakathi komzimba we-valve kanye nezingxenye zokuvala, okuholela ekutheni i-valve ayikwazi ukuvalwa ngokugcwele endaweni.
1.2 Ukungcola kukhona kuvalvu
Enye imbangela yokuvuza kwe-valve njalo ukuba khona kokungcola ku-valve. Lokhu kungcola kungase kube isihlabathi, amatshe, ukugqwala, i-welding slag, njll, kodwa futhi kungase kube amathuluzi, izinduku zokushisela, izinduku zezinkuni, imikhiqizo yepulasitiki nezinye izinto ezifanayo ezitholakala endaweni yokwakha. Lezi zinkinga zibangelwa kakhulu yizizathu ezilandelayo:
(1) Ngemva kokuhlolwa kwe-hydraulic komkhiqizi wamavalvu, amanzi asenhlanhleni awakhishwa, noma amanzi awomisiwe, avimbela ukubola, amafutha okugcoba nezinye izindlela zokuzivikela, okuholela ekugqwaleni kwangaphakathi kwevalvu futhi kubangele ukuvuza kwangaphakathi;
(2) Indawo yokwakha ayivikelekile kahle nhlangothi zombili zevalvu ngaphambi kokufakwa kwesivalo, okuholela ekutheni kube nenhlabathi, imvula, amatshe nokunye ukungcola emseleni ophakathi kwesivalo sesihlalo se-valve kanye nomzimba wevalvu, isihlalo “O ” indandatho noma i-spring groove, okuholela ekuvuzeni kwangaphakathi.
(3) Ngesikhathi senqubo yokwakha, ukusebenza akuhambisani nemithetho, futhi imininingwane yokwakha ayinakwa. Amathuluzi abasebenzi, ama-electrode okushisela nezinye izinto ezisetshenziswa endaweni yokwakha zingena kuvalvu, okubangela ukuvuza kwangaphakathi kwe-valve.
(4) ngokuvamile isenzo sokunqwabelana kwevalvu, udaka noma ukungcola endaweni yokuvala, ukwakha umcamelo oqinile noma ukunqwabelana kwe-valve yesango kuningi kakhulu, akukwazi ukuvalwa endaweni, okuholela ekuvuzeni kwangaphakathi.
(5) Ngaphambi nangemuva kokufakwa kwevalvu, igrisi efanelekile ayijovwa ngesikhathi, futhi ukungcola kungena emgodini phakathi kwesivalo sesihlalo sevalvu, indandatho ethi “O” yesihlalo sevalvu noma i-spring groove. , okuholela ekuvuzeni kwangaphakathi.
(6) Ukugqokwa kwengulube akunakekelwa ngaphambi nangemuva, okuholela ekunqwabeleni kokungcola noma ukungena emseleni ngemva kwesihlalo, okuholela ekuvaleni kahle.
(4) Ivalvu evalwe ngamafutha okuvalwa ayinezelwa ngesikhathi, okuholela esilinganisweni esinganele samafutha okuvala ukuze akhe ukuvuza kwangaphakathi.
