Ukuhlaziywa kokuphepha kwemboni ye-petrochemical encike kuma-valve eglobhu ensimbi ajwayelekile aseMelika

Embonini ye-petrochemical, ukuphepha kuwukucatshangelwa okuyinhloko kokuklama nokusebenza. Amavalvu eglobhu ensimbi ajwayelekile aseMelika akhiwe yi-American National Standard (ANSI) kanye ne-American Petroleum Institute (API) abe yimikhiqizo ekhethwayo embonini ngenxa yezimpawu zabo ezinhle kakhulu zokuphepha. Lesi sihloko sizohlola ukusetshenziswa kwalawa ma-valve embonini ye-petrochemical kanye nokuhlaziywa kokuphepha kwawo.

Isizinda sohlelo lokusebenza

Uketshezi olubandakanyeka embonini ye-petrochemical ngokuvamile lunezici ezinjengokuvutha, ukuqhuma, kanye nokugqwala okuqinile. Ngakho-ke, kuyadingeka ukuthi ama-valve ezinhlelweni zamapayipi kufanele abe nokuthembeka okuphezulu nokuqina. Amavalvu eglobhu ensimbi asetshenziswa kabanzi ezindaweni zokuhluza, izitshalo zamakhemikhali, izizinda zikawoyela, nakwezinye izindawo ukuze kulawulwe ukugeleza kwemithombo yezindaba efana nowoyela ongahluziwe, igesi yemvelo nezinto zamakhemikhali.

Izici zokuphepha

1. Impahla namandla: Ngokwemithetho ye-ASTM, izinto ezisetshenziselwa ama-valve eglobhu ensimbi ajwayelekile aseMelika angakwazi ukumelana nezimo zokusebenza ngokwedlulele ezifana nezinga lokushisa eliphezulu, ukucindezela okukhulu, nokugqwala okuqinile, okuqinisekisa ubuqotho nokuzinza kwe-valve ngaphansi kwezimo ezinzima.
2. Ukusebenza kokuvala: I-valve iklanywe ngendlela yokuvala enhle ukuze kuqinisekiswe umphumela omuhle wokuvala esimweni esivaliwe, ukuvimbela ngokuphumelelayo ukuvuza kwemidiya eyingozi futhi kunciphise ingozi yomlilo nokuqhuma.
3. Idizayini yokuvikela umlilo: Amanye ama-valve ajwayelekile aseMelika e-cast cast steel globe aklanywe ngezakhiwo zokuphepha komlilo ngokuvumelana nezindinganiso ze-API 607, ezingagcina ikhono lokuvala isikhathi esithile ngisho nasezindaweni zomlilo ezishisa kakhulu, zinikeze isikhathi esibalulekile sokuphuma okuphephile esimweni esiphuthumayo. izimo.
4. Ukuvikela i-Blowout: Ngemithombo yegesi enomfutho ophezulu, i-valve ifakwe isivimbeli sokuphuma ukuze kugwenywe izingozi zokuphepha ezibangelwa isiqu se-valve siphushwa indawo ephakathi nendawo phakathi nokukhuphuka kwengcindezi ngokushesha.
5. Ukunakekelwa okufanele: Idizayini yamavalvu eglobhu ensimbi ajwayelekile aseMelika kulula ukuyihlola nokuyinakekela, isiza ukuhlonza izinkinga ezingaba khona ngesikhathi kanye nokuzilungisa, kunciphise ukuvela kwezingozi.

Ukuhlolwa kokusebenza kokuphepha

1. Ukuhlolwa kokucindezela: Phakathi nenqubo yokukhiqiza, i-valve ngayinye ibhekana nokuhlolwa kwengcindezi eqinile ukuze kuqinisekiswe umfutho wayo omkhulu wokusebenza nokuqinisekisa ukuthi ayisebenzi kabi ngenxa yokweqa ububanzi bengcindezi ekusetshenzisweni kwangempela.
2. Ukuhlola ukuvuza: Yenza ukuhlolwa okuqinile kokuvuza ku-valve ukuze uqinisekise ukuthi ukusebenza kwayo kokuvala kuhlangabezana nezidingo eziqinile zamazinga okuvuza ezinhlelweni zezimboni.
3. Ukuhlola ukumelana nomlilo: Ngokuhlola okujwayelekile kokumelana nomlilo, kuqinisekisa ukuthi ivalvu ingakwazi ukugcina ukusebenza kwayo noma isimo esivaliwe isikhathi esithile uma kuba nomlilo, inikeze amathuba okusingatha izimo eziphuthumayo.
4. Ukuphathwa komjikelezo wokuphila: Ngokuhlola impilo yesevisi nokugcinwa ngezikhathi ezithile kwamavalvu, izingozi zokuphepha ezingaba khona zingabikezelwa futhi zigwenywe, ngaleyo ndlela kuqinisekiswe ukusebenza okuphephile kwesikhathi eside.

Kafushane, embonini ye-petrochemical, ama-valve eglobhu ensimbi ajwayelekile aseMelika asephenduke ingxenye ebalulekile ekuqinisekiseni ukuphepha kwemboni ngenxa yomklamo wawo oqinile ojwayelekile, ukusebenza okuhle kakhulu kokuvala, kanye nomlilo okhethekile kanye nemisebenzi yokuvikela. Ngokulungiswa nokuphathwa okuvamile, lawa ma-valve awagcini nje ngokuhlinzeka ngokwethembeka ekulawuleni inqubo, kodwa futhi anikeze iziqinisekiso eziqinile zokuphepha kokukhiqiza kanye nabasebenzi kuyo yonke imboni. Ngokuthuthuka kobuchwepheshe, ukusebenza kokuphepha kwalawa mavalvu kuzothuthukiswa ngokuzayo ukuze kuhlangatshezwane nesidingo esikhulayo sokuphepha kwezimboni.
