"Ukukhethwa Kwamavalvu Ase-American Standard Cast Steel Globe: Imihlahlandlela Yezicaciso, Izilinganiso Zengcindezi, Nezinto Zokusebenza"

I-valve yeglobu yensimbi ejwayelekile yaseMelika iyi-valve yezimboni evame ukusetshenziswa, esetshenziswa kabanzi emikhakheni efana ne-petroleum, amakhemikhali, nokwelashwa kwamanzi. Kubalulekile ukukhetha ivalvu yeglobu yensimbi esezingeni elijwayelekile yaseMelika ukuze kuqinisekiswe ukusebenza okuphephile kwemishini kanye nokwenza kahle inqubo yokukhiqiza. Lesi sihloko sizokwethula imingcele ebalulekile okufanele uyinake lapho ukhetha amavalvu eglobhu ensimbi ajwayelekile aseMelika, okuhlanganisa imininingwane, izilinganiso zokucindezela, nezinto zokwakha, ukukusiza wenze ukukhetha okuhlakaniphile.

1. Ukukhetha imininingwane

1. Idayamitha encane: Ububanzi obujwayelekile bamavalvu embulunga yensimbi esakazwa yaseMelika kufanele ifane nobubanzi bohlelo lwamapayipi. Khetha ukucaciswa kwe-valve efanele ngokusekelwe ezidingweni zangempela.
2. ingcindezi yamagama: ukucindezela okuzisholo kubhekisela ekucindezelweni okuphezulu i-valve engakwazi ukumelana nayo ngaphansi kwezimo ezivamile zokusebenza. Lapho ukhetha ama-valve eglobhu ensimbi ajwayelekile aseMelika, kufanele kuqinisekiswe ukuthi ukucindezela okuzisholo kwevalvu kukhulu noma kulingana nokucindezela okuphezulu kokusebenza kwesistimu yamapayipi.
3. Indlela yokuxhuma: Izindlela zokuxhuma zamavalvu eglobhu ensimbi ajwayelekile aseMelika ahlanganisa uxhumo oluluchungechunge, uxhumano lwe-flange, njll. Khetha indlela yokuxhumana efanele ngokusekelwe ezidingweni zangempela.

2. Ukukhetha izinga lokucindezela

Isilinganiso sokucindezela samavalvu eglobhu ensimbi ajwayelekile yaseMelika ngokuvamile sihlukaniswa ngamaleveli amane: ukucindezela okuphansi, ukucindezela okuphakathi, ukucindezela okuphezulu, nokucindezela okuphezulu kakhulu. Lapho ukhetha, izinga lokucindezela elifanele kufanele likhethwe ngokusekelwe ezimweni zangempela zokusebenza.

1. Isilinganiso sokucindezela okuphansi: sifanele izimo lapho ingcindezi emaphakathi ingaphansi noma ilingana no-1.6MPa.
2. Isilinganiso sokucindezela okumaphakathi: sifanele izimo lapho ingcindezi emaphakathi ingaphezu kuka-1.6 MPa futhi ingaphansi noma ilingana no-10.0 MPa.
3. Izinga lokucindezela okuphezulu: lifanele izimo lapho ingcindezi emaphakathi ingaphezu kuka-10.0MPa futhi ingaphansi noma ilingana no-42.0MPa.
4. I-Ultra high pressure level: ifanele izimo lapho ingcindezi emaphakathi ingaphezu kuka-42.0MPa.

3, Ukukhetha impahla

Izinto ezisetshenziswayo zamavalvu eglobhu ensimbi ajwayelekile aseMelika anomthelela omkhulu ekumelaneni nokugqwala kwawo, ukumelana nezinga lokushisa namandla. Khetha izinto ezifanele zamavalvu, njengensimbi ye-carbon, insimbi engagqwali, ingxubevange, njll., ngokusekelwe ezimpahleni zendlela yokudlulisa.

1. I-Carbon steel material: ifanele izimo zokusebenza ezijwayelekile lapho okuphakathi kungamanzi, umusi, uwoyela, njll.
2. Izinto zensimbi engagqwali: zilungele izimo zokusebenza ezinoketshezi olubolayo, amagesi, njll., futhi inokumelana nokugqwala okuhle.
3. I-alloy material: ifanele izimo zokusebenza ezikhethekile ezifana nokushisa okuphezulu, ukucindezela okuphezulu, nokugqwala, okunamandla aphezulu kanye nokumelana nokugqwala.

Isifinyezo:

Ukukhetha ivalvu yeglobu yensimbi esezingeni elijwayelekile yaseMelika kudinga ukucatshangelwa okugcwele kwamapharamitha abalulekile njengokucaciswa, amazinga okucindezela, nezinto zokwakha. Kubunjiniyela obusebenzayo, ukucaciswa kwamavalvu, amazinga okucindezela, nezinto zokwakha kukhethwa ngokunengqondo ngokusekelwe ezidingweni nezici ezimaphakathi zezinhlelo zamapayipi ukuqinisekisa ukusebenza okuphephile, okuzinzile, nokusebenza kahle kwamavalvu. Uma kunezidingo ezikhethekile, ama-valve eglobhu ensimbi ajwayelekile aseMelika anezakhiwo ezikhethekile angenziwa ngokwezifiso ukuze ahlangabezane nezidingo zezimo ezithile zokusebenza.
